Line of credit facility, covenant terms |  |  |  |  | The Credit Agreement includes the following financial condition covenants that we are required to satisfy: (i) maintain a minimum liquidity limit of $125 million for each quarter; (ii) maintain a 3.75 times leverage ratio; and (iii) maintain a 1.5 times interest coverage ratio. The leverage and interest coverage ratios will be triggered when we achieve $50 million in adjusted EBITDA over a trailing twelve months, or upon our election if we have achieved positive adjusted EBITDA over a trailing twelve months. Once the leverage and interest coverage ratios are triggered the minimum liquidity limit will not have a minimum limit. Minimum liquidity includes unrestricted cash plus the undrawn balance of the revolving credit facility. The minimum liquidity covenant was the only financial condition covenant we had to satisfy as of the period ended December 31, 2021 |  |  |  |
