Credit Lines

Devon has a $3.0 billion Senior Credit Facility. As of June 30, 2018, Devon had $51 million in outstanding letters of credit under the Senior Credit Facility. There were no outstanding borrowings under the Senior Credit Facility at June 30, 2018. The Senior Credit Facility contains only one material financial covenant. This covenant requires Devon’s ratio of total funded debt to total capitalization, as defined in the credit agreement, to be no greater than 65%. Under the terms of the credit agreement, total capitalization is adjusted to add back noncash financial write-downs such as impairments. As of June 30, 2018, Devon was in compliance with this covenant with a debt-to-capitalization ratio of 26.1%.
