In the first quarter 2022, we acquired assets for $30 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 first quarter 2022 and the two following quarters. Thereafter, the covenant will decrease to 5.0 to 1.
