Accounting Policies [Abstract]
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amount of revenues and expenses during the reporting period. Actual results could differ from those estimated.

ASU 2016-13 replaces the incurred loss impairment methodology under previous GAAP by requiring entities to measure credit losses of certain financial assets, including trade receivables, utilizing a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates.

Restricted Cash	Restricted Cash We maintain restricted cash bank accounts, which are subject to restrictions due to Bankruptcy Court order, to settle certain professional fees incurred upon or prior to our emergence from bankruptcy. See Note 2. We classify such restricted cash accounts in current assets if the restrictions are expected to expire or otherwise be resolved within one year or if such funds are considered to offset current liabilities. At June 30, 2020, our restricted cash was considered to be current and was recorded in “Restricted cash” in our unaudited Condensed Consolidated Balance Sheets. See Note 7.
