Income Tax Disclosure [Abstract]
Income Taxes	9. Income Taxes The Company did not record a provision or benefit for income taxes during the three months ended March 31, 2017 and 2016, respectively, as it reported losses in each period which are not more likely than not to be realized. Due to the uncertainties surrounding the realization of deferred tax assets through future taxable income, the Company has provided a full valuation allowance and, therefore, no benefit has been recognized for the net operating loss carryforwards and other deferred tax assets. At December 31, 2016, the Company had $0.6 million of unrecognized tax benefit, none of which, if recognized, would affect the effective tax rate as most of the unrecognized tax benefit is deferred tax assets currently offset by a valuation allowance. The Company has not recognized any interest and penalties related to uncertain tax positions as part of the income tax provision. A number of years may elapse before an uncertain tax position is audited and finally resolved. While it is often difficult to predict the final outcome or the timing of resolution of any particular uncertain tax position, the Company believes that its reserves for income taxes reflect the most likely outcome. The Company adjusts these reserves, as well as the related interest, in light of changing facts and circumstances. Settlement of any particular position could require the use of cash. As of March 31, 2017, changes to the Company’s uncertain tax positions in the next twelve months that are reasonably possible are not expected to have a material impact on the Company’s financial position or results of operations.
