Covenant Requirement \| Credit facility
Debt Instrument [Line Items]
Line of credit interest terms						We pay interest on revolver borrowings under the credit facility at floating rates equal to LIBOR (with a minimum floor of 15 basis points) plus a margin
Debt instrument covenant description						Additionally, total debt used in the calculation of our leverage ratio is based on a “net debt” concept, under which cash and cash equivalents in excess of $100 million are deducted from our total debt balance. During the phase-in period after exiting the covenant waiver period, instead of using the prior four calendar quarters’ results in the calculations of the required financial maintenance covenants, only results for the exit quarter and thereafter are used. In addition, for the first testing quarter after the covenant waiver period (i.e., the quarter ended September 30, 2021), the only financial covenant that was required to be satisfied was a minimum fixed charge coverage ratio of 1.0x as of the end of the quarter. For the fiscal quarters ending after the covenant waiver period (i.e., after September 30, 2021), the financial covenant requirements set forth in the credit facility before the Amendments apply, except that the maximum leverage ratio requirement will be amended to be (a) 8.50x as at the end of the first and second fiscal quarters ending after the covenant waiver period, (b) 8.0x as at the end of the third and fourth fiscal quarters ending after the covenant waiver period, (c) 7.50x as at the end of the fifth fiscal quarter ending after the covenant waiver period and (d) 7.25x at all times thereafter.
