Income Taxes	9 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income TaxesOur effective income tax rate is 0% for the three and nine months ended September 30, 2020 and 2019. Total income tax differs from the amounts computed by applying the statutory income tax rate to loss before income tax primarily as a result of our valuation allowance. We assessed whether we had any significant uncertain tax positions taken in a filed tax return, planned to be taken in a future tax return or claim, or otherwise subject to interpretation and determined there were none not more likely than not to be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position, or prospectively approved when such approval may be sought in advance. Accordingly, we recorded no reserve for uncertain tax positions. Should a provision for any interest or penalties relative to unrecognized tax benefits be necessary, it is our policy to accrue for such in our income tax accounts. There were no such accruals as of September 30, 2020 and December 31, 2019 and we do not expect a significant change in gross unrecognized tax benefits in the next twelve months. Our tax years after 2011 remain subject to examination by the Internal Revenue Service and by the taxing authorities in the states and territories in which we operate. We conduct operations in the U.S. territories of Puerto Rico, Guam and the Commonwealth of the Northern Mariana Islands. As a result, our income tax expense includes the effects of taxes incurred in such jurisdictions where the tax code for the respective jurisdiction may have separate tax-reporting requirements. Jurisdiction-specific income taxes, in aggregate, do not adjust our effective income tax rate of 0%. In March 2020, the U.S. enacted the Coronavirus Aid, Relief, and Economic Security Act ("CARES Act"), featuring significant tax provisions and relief measures to assist individuals and businesses impacted by the economic effects of the COVID-19 pandemic. Relief measures intended to aid businesses in employee retention include payroll tax relief and a refundable tax credit for employers who retain employees during the COVID-19 pandemic. In addition, among other things, the CARES Act establishes (a) a five-year carryback of net operating losses generated in 2018, 2019 and 2020, (b) a temporary suspension of the 80% limitation on the use of net operating losses in 2018, 2019 and 2020 and (c) an increase to the adjusted taxable income limitation from 30% to 50% for business interest deductions under Section 163(j) of the U.S. Internal Revenue Code of 1986, as amended, for 2019 and 2020. We have historically maintained, and continue to maintain, a full valuation allowance against deferred tax assets. Due to our aggregate amount of net operating losses, we cannot utilize the carryback or limitation suspension provisions pertaining to the usage of net operating losses. However, the increase to the adjusted taxable income limitation for business interest deductions resulted in a decrease to our deferred tax assets for unused business interest deductions and an offsetting increase to our net operating loss carryforward. The CARES Act does not have any impact on our valuation allowance.
