As of June 30, 2021, the Partnership had $360.0 million of qualifying receivables under its $400.0 million accounts receivable securitization facility (“Securitization Facility”), resulting in $40.0 million availability. During the second quarter of 2021, the Partnership amended the Securitization Facility to increase the facility size from $350.0 million to $400.0 million to more closely align with our expectation for borrowing needs given current commodity prices and to extend the facility termination date to April 21, 2022.

While we consolidate the debt of the Partnership in our financial statements, we do not have the obligation to make interest payments or debt payments with respect to the debt of the Partnership.
