In the nine months ended September 30, 2020 and in connection with the Fifth Amendment, the Company incurred issuance costs of $1.7 million, of which $0.4 million has been charged to Interest expense, net. The remainder was capitalized as unamortized debt issuance costs and is being amortized to Interest expense, net over the remaining term of the Credit Agreement.

The Company may make prepayments against the amended Senior Credit Facility, in whole or in part, without premium or penalty. The Company would be required to prepay certain outstanding amounts in the event of certain circumstances or transactions. In April 2020, with the net proceeds generated from the divestiture of the Domestic Environmental Solutions business, the Company made principal repayments of approximately $430.0 million, which excluded certain transaction costs, final working capital adjustments, or other adjustments associated with the divestiture.

As of September 30, 2020, the Company was in compliance with its Consolidated Leverage Ratio covenant, with an actual ratio of 3.75 to 1.00, which was below the allowed maximum ratio of 4.75 to 1.00 as set forth in the Fifth Amendment. On April 6, 2020, the Company completed the divestiture of the Domestic Environmental Solutions business. Therefore, effective April 6, 2020, the Consolidated Leverage Ratio decreased by 0.25 to 4.75 to 1.00 for fiscal quarters ending on or before December 31, 2021 and 4.25 to 1.00 for fiscal quarters ending on or after March 31, 2022.

Given our current leverage position, we believe that we should be able to operate within our covenant thresholds, but due to the unpredictability of the COVID-19 pandemic and situations outside our control, it is reasonably likely we could exceed this Consolidated Leverage Ratio threshold at some point in the next 12 months. This risk can be mitigated and potentially managed through appropriate spending controls, divestitures, restructuring the Company’s existing indebtedness, amending the Credit Agreement, or seeking temporary relief from the Consolidated Leverage Ratio covenant from the Company’s lenders.

A failure to comply with these covenant provisions could result in an event of default. Upon an event of default, unless waived, the lenders could elect to terminate their commitments, cease making further loans, and/or cause their loans to become due and payable in full, foreclose against the assets securing the debt under our Credit Agreement and force us and our subsidiaries into bankruptcy or liquidation.
