2027 Senior Notes

On October 16, 2019, the Partnership completed an offering (the “Notes Offering”) of $500.0 million in aggregate principal amount of its 5.375% Senior Notes due 2027 (the “Notes”). The Partnership received net proceeds of approximately $490.0 million from the Notes Offering. The Partnership loaned the gross proceeds to the Operating Company. The Operating Company used the proceeds from the Notes Offering to pay down borrowings under its revolving credit facility. During the second quarter of 2020, the Partnership repurchased $14.1 million of the outstanding principal of the Notes at a cash price ranging from 97.5% to 98.5% of the aggregate principal amount, which resulted in an immaterial gain on extinguishment of debt. As of June 30, 2020, the remaining outstanding principal amount of Notes totaled $485.9 million and will mature on November 1, 2027.

The Operating Company’s Revolving Credit Facility

On July 20, 2018, the Partnership, as guarantor, entered into an amended and restated credit agreement with the Operating Company, as borrower, Wells Fargo National Bank (“Wells Fargo”), as administrative agent, and the other lenders. The credit agreement, as amended to date, provides for a revolving credit facility in the maximum credit amount of $2.0 billion and a borrowing base based on the Operating Company’s oil and natural gas reserves and other factors. The Partnership’s borrowing base was reduced from $775.0 million to $580.0 million during the scheduled semi-annual redetermination in the second quarter of 2020. The borrowing base is scheduled to be re-determined semi-annually in May and November. In addition, the Operating Company and Wells Fargo each may request up to three interim redeterminations of the borrowing base during any 12-month period. As of June 30, 2020, there was $426.5 million available for future borrowings under the Operating Company’s revolving credit facility. During the three and six months ended June 30, 2020, the weighted average interest rates on the Operating Company’s revolving credit facility were 2.41% and 2.82%, respectively. The revolving credit facility will mature on November 1, 2022.

As of June 30, 2020, the Operating Company was in compliance with the financial maintenance covenants under its credit agreement.
