Revolving Credit Agreement

On April 22, 2019, the Company entered into a second amended and restated credit agreement (the revolving credit facility). The Company's revolving credit facility is unsecured and the borrowing base is redetermined annually on April 1. In addition, either the Company or the banks may request an interim redetermination twice a year or in connection with certain acquisitions or divestitures of oil and gas properties. The Company’s borrowing base and available commitments under the revolving credit facility were $3.2 billion and $1.5 billion, respectively. The maximum revolving credit available to the Company is the lesser of the available commitments or the difference of the borrowing base less outstanding senior notes. The

Company's revolving credit facility matures in April 2024 and can be extended by one year upon the agreement of the Company and lenders holding at least 50 percent of the commitments under the revolving credit facility.

Interest rates under the revolving credit facility are based on LIBOR or ABR indications, plus a margin which ranges from 150 to 225 basis points for LIBOR loans and from 50 to 125 basis points for ABR loans when not in an Investment Grade Period (as defined in the amended and restated credit agreement) and from 112.5 to 175 basis points for LIBOR loans and from 12.5 to 75 basis points for ABR loans during an Investment Grade Period. The revolving credit facility also provides for a commitment fee on the unused available balance and is calculated at annual rates ranging from 30 to 42.5 basis points when not in an Investment Grade Period and from 12.5 to 27.5 basis points during an Investment Grade Period. The Company is currently not in an Investment Grade Period.

The revolving credit facility contains various customary covenants, which include the following (with all calculations based on definitions contained in the amended and restated credit agreement):


•	Maintenance of a minimum asset coverage ratio of 1.75 to 1.0;


•	Maintenance of a minimum annual coverage ratio of consolidated cash flow to interest expense for the trailing four quarters of 2.8 to 1.0; and


•	Maintenance of a minimum current ratio of 1.0 to 1.0.

At June 30, 2019, the Company had no borrowings outstanding under its revolving credit facility and had unused commitments of $1.5 billion.

The Company incurred $7.4 million of debt issuance costs in connection with the amended and restated credit agreement, which were capitalized and will be amortized over the term of the amended and restated agreement. The remaining unamortized costs of $3.4 million will also be amortized over the term of the amended and restated agreement in accordance with ASC 470-50, Debt Modifications and Extinguishments.
