Credit Agreement, covenant terms |
|
|
The Credit Facility contains financial covenants that require us to maintain a Leverage Ratio of consolidated indebtedness to consolidated EBITDA of no more than 3 times for the most recently ended 12-month period (EBITDA is defined as earnings before interest, taxes, depreciation and amortization) and an Interest Coverage Ratio of consolidated EBITDA to interest expense of at least 5 times for the most recently ended 12-month period.
|
|
|
|
Credit Agreement, covenant compliance |
|
|
At March 31, 2016 we were in compliance with these covenants as our Leverage Ratio was 2.1 times and our Interest Coverage Ratio was 11.9 times.
