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). In 2020, we acquired additional interest in one of our equity investments and a related asset for $27 million, which allowed us to elect an acquisition adjustment period under our $2.5 Billion Credit Agreement and, as a result, increased our leverage ratio covenant to 5.5 to 1 for the fourth quarter 2020 and the two following quarters. Thereafter, the covenant will decrease to 5.0 to 1. |
