Debt Instrument, Covenant Description | Among other things, these covenants include maintaining a ratio of indebtedness to adjusted EBITDA (EBITDA, as defined in our $2.5 Billion Credit Agreement, adjusted for all noncash charges and increased for projected EBITDA from certain lender-approved capital expansion projects) of no more than 5.0 to 1 at September 30, 2019. If we consummate one or more acquisitions in which the aggregate purchase is $25 million or more, the allowable ratio of indebtedness to adjusted EBITDA will increase to 5.5 to 1 for the quarter in which the acquisition is completed and the two following quarters. Thereafter, the covenant will decrease to 5.0 to 1. At September 30, 2019, we had no borrowings outstanding, our ratio of indebtedness to adjusted EBITDA was 3.8 to 1, and we were in compliance with all covenants under our $2.5 Billion Credit Agreement. |
