|Income Tax Disclosure [Abstract]|
As of June 30, 2018 and December 31, 2017, the Company’s liability for gross unrecognized tax benefits totaled $1.2 million and $1.1 million, respectively (excluding interest and penalties). The Company had no accrued interest and penalties relating to unrecognized tax benefits at June 30, 2018 and had $1,400 of accrued interest and penalties relating to unrecognized tax benefits on a gross basis at December 31, 2017. The change in the liability for gross unrecognized tax benefits reflects an increase in reserves established for federal and state research and development credits. Additionally, the Company continues to analyze the different aspects of the Tax Cuts and Jobs Act of 2017 which could potentially affect the provisional estimates that were recorded at December 31, 2017. During the six months ended June 30, 2018, there were no changes made to the provisional amounts recognized in 2017. The Company does not currently expect significant changes in the amount of unrecognized tax benefits during the next twelve months.
