The Solar Facility includes a financial covenant requiring the attainment of a minimum trailing net revenue amount beginning on December 31, 2020. The Company and lenders executed the Solar Amendment in December 2020 that reduced the minimum trailing net revenue covenant requirement amounts beginning on December 31, 2020 to allow the Company to maintain compliance with the covenant as of December 31, 2020. As of September 30, 2021, the Company is in compliance with the financial covenant and is projected to be in compliance with the reduced minimum revenue covenant amounts going forward.
As of September 30, 2021, the Company is in compliance with all covenants in the Solar Facility.
The Solar Facility includes a financial covenant requiring the attainment of a minimum trailing net revenue amount. Based upon the Company’s projected revenues for the remainder of 2021, the Company believes that it is probable that this minimum revenue covenant will not be achieved. The Company is in discussions with the lenders for a potential covenant waiver or amendment, however, no formal agreement has been executed. The Solar Facility also includes subjective acceleration clauses which permit the lenders to accelerate the maturity date under certain circumstances, including, but not limited to, material adverse effects on a Company’s financial status or otherwise. In accordance with FASB ASC 470 as the Solar Facility contains subjective acceleration clauses and the assessment that it is probable that the revenue covenant will not be met as of December 31, 2021, the outstanding principal under the Solar Facility is classified as a current liability in the accompanying balance sheet as of September 30, 2021.
