Summit Midstream Partners, LP announced impairment charges for the fourth quarter ended December 31, 2020. For the quarter, the company reported that net income for the quarter was primarily driven by approximately $124 million of gain on the early extinguishment of debt from the Partnership's open market repurchase of its senior unsecured notes and the consensual debt discharge and restructuring of a subsidiaries' $155.2 million term loan ("GP Term Loan Restructuring"), partially offset by an approximate $5 million asset impairment charge for an $8 million sale of compressor equipment completed in January 2021.
