Income Tax Disclosure [Abstract]  

The Company's income tax provision (benefit) for interim periods is determined using an estimate of the Company's annual effective tax rate, adjusted for discrete items, if any, that are taken into account in the relevant period.
The Company's income tax provision was zero for both the three and six months ended June 30, 2019 and 2018.
In assessing the realizability of deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which temporary differences become deductible.

The Company recorded a valuation allowance against its deferred tax assets as of June 30, 2019 as management does not believe that it is more likely than not that the deferred tax assets will be realized.

At December 31, 2018, the Company reported a total liability for unrecognized tax benefits of $0.7 million. The Company does not anticipate any significant increases or decreases to the balance of unrecognized tax benefits during the next 12 months.
