| Credit facility covenants compliance |
|
|
|
|
|
The financial covenants require the Company to maintain a maximum leverage ratio, defined as consolidated funded debt divided by consolidated EBITDA (as set forth in the Senior Credit Facilities) for the preceding four quarters, of not more than 3.5 to 1.0. The Company may, subject to the terms of the Senior Credit Facilities, increase the covenant by 0.5 (i.e. to 4.0 to1.0) for a four consecutive fiscal quarter period following a material acquisition. As permitted under the terms of the Senior Credit Facilities, we made the election to increase the covenant to 4.0 to 1.0, effective for four consecutive quarters, beginning with the first quarter of 2016 and continuing through the fourth quarter of 2016. Compliance with this financial covenant is tested quarterly. The non-financial covenants include limitations on liens, subsidiary debt, mergers, liquidations, asset dispositions and acquisitions. As of December 31, 2016, we were in compliance with our covenants under the Senior Credit Facilities.
