Debt

Senior Notes. As of June 30, 2021, we are below the EBITDA-to-interest coverage ratio covenant requirement of our senior notes indenture necessary to incur additional debt, and, therefore, while not an event of default, we will be unable to incur additional debt while we remain below the required covenant level.  

Credit Facility. As of June 30, 2021, we have $12 million of available capacity under the revolver portion of our credit facility. Due to the failure to satisfy the senior notes indenture covenant requirement noted above, we currently are restricted from incurring additional debt.
