Debt Disclosure [Text Block]	NOTE 2 – LONG-TERM DEBT The carrying value of the Company’s Senior Secured Debt approximates fair value. The fair value of the Company’s Senior Secured Debt (Level 2) is determined based on an estimation of discounted future cash flows of the debt at rates currently quoted or offered to the Company by its lenders for similar debt instruments of comparable maturities by its lenders. In March 2020, the Company entered into an agreement that provides it the right, at its option, to extend the contractual May 25, 2021 maturity of its Senior Secured Debt of approximately $80.7 million as of March 31, 2021 until May 25, 2022. On March 24, 2021, the Company entered into an additional agreement which provides it the right, at its option, to further extend the maturity date of its Senior Secured Debt to November 25, 2022. The fee to acquire this second extension option was the adjustment of the exercise price of 362,500 warrants held by Apollo from $6.75 to $0.01 (“Warrant Modification”). The Company currently intends to exercise its first extension option to extend the maturity date to May 25, 2022. As a result of the Warrant Modification, the Company reclassified the carrying value of the warrant prior to the modification from a warrant liability in the amount of $1.3 million to additional paid-in capital. In addition, the Company recorded debt issuance costs in the amount of $1.9 million, which was the increase in fair value of the warrant at the time of the modification, with a corresponding adjustment to additional paid-in capital. The debt issuance costs will be amortized over the remaining life of the Senior Secured Debt. Prior to the Warrant Modification, the fair value of the warrant was remeasured each reporting period using an option pricing model, and the change in fair value was recorded as an adjustment to the recorded warrant liability with the unrealized gains or losses reflected in interest expense. On May 10, 2021, Apollo exercised 362,500 warrants, which allowed them to purchase 362,500 shares of common stock at $0.01 per share. As of March 31, 2021, the Company recognized a gain of $573 thousand related to the remeasurement of the warrant liability prior to the Warrant Modification.
