Line of credit facility covenant terms					In August 2020, the Company entered into an amendment to the MidCap Credit Facility, pursuant to which the parties agreed that no breach of the minimum Afrezza net revenue covenant for any trailing twelve-month reporting period between July 31, 2020 and November 30, 2020 will be deemed to occur if the Company delivers satisfactory evidence that it had unrestricted cash of at least $40.0 million. Without this amendment, the Company would have been in violation of the minimum Afrezza net revenue covenant as of September 30, 2020. After the November 30, 2020 reporting period, the amendment will expire and a breach of the minimum Afrezza net revenue covenant is probable. The Company intends to amend the MidCap Credit Facility to address this probable covenant violation; however, such amendment, if completed, would occur after the date of this report.
