Accounts Receivable Securitization. On December 5, 2014, certain direct and indirect wholly owned subsidiaries of our Intermediate Partnership entered into a $100.0 million accounts receivable securitization facility ("Securitization Facility"). Under the Securitization Facility, certain subsidiaries sell trade receivables on an ongoing basis to our Intermediate Partnership, which then sells the trade receivables to AROP Funding, LLC ("AROP Funding"), a wholly owned bankruptcy-remote special purpose subsidiary of our Intermediate Partnership, which in turn borrows on a revolving basis up to $100.0 million secured by the trade receivables. After the sale, Alliance Coal, as servicer of the assets, collects the receivables on behalf of AROP Funding. The Securitization Facility bears interest based on a Eurodollar Rate. It was renewed in January 2019 and matures in January 2020. At June 30, 2019, we had $75.0 million outstanding balance under the Securitization Facility.
Cavalier Credit Agreement. On October 6, 2015, Cavalier Minerals (see Note 9 – Variable Interest Entities) entered into a credit agreement (the "Cavalier Credit Agreement") with Mineral Lending, LLC ("Mineral Lending") for a $100.0 million line of credit (the "Cavalier Credit Facility"). The commitment under the Cavalier Credit Facility is reduced by any distributions received from Cavalier Minerals' investment in AllDale II. As of June 30, 2019, the commitment under the Cavalier Credit Facility was $67.5 million. Mineral Lending is an entity owned by (a) Alliance Resource Holdings II, Inc. ("ARH II"), an entity owned by Joseph W. Craft III, the Chairman, President and Executive Officer of MGP ("Mr. Craft") and Kathleen S. Craft, (b) an entity owned by an individual who is an officer and director of ARH II and (c) charitable foundations established by Mr. Craft and Kathleen S. Craft. There is no commitment fee under the facility. Mineral Lending's obligation to make the line of credit available terminates no later than October 6, 2019. Borrowings under the Cavalier Credit Facility bear interest at a one month LIBOR rate plus 6% with interest payable quarterly, and mature on September 30, 2024, at which time all amounts then outstanding are required to be repaid. The Cavalier Credit Agreement requires repayment of the principal balance beginning in 2018, in quarterly payments of an amount equal to the greater of $1.3 million initially, escalated to $2.5 million after two years, or fifty percent of Cavalier Minerals' excess cash flow. To secure payment of the facility, Cavalier Minerals pledged all of its partnership interests, owned or later acquired, in AllDale I & II. Cavalier Minerals may prepay the Cavalier Credit Facility at any time in whole or in part subject to terms and conditions described in the Cavalier Credit Agreement. As of June 30, 2019, Cavalier Minerals had not drawn on the Cavalier Credit Facility.
Equipment Financing. On May 17, 2019, the Intermediate Partnership entered into an equipment financing arrangement accounted for as debt, wherein the Intermediate Partnership received $10.0 million in exchange for conveying its interest in certain equipment owned by an indirect wholly-owned subsidiary of the Intermediate Partnership and entering into a master lease agreement for that equipment (the “Equipment Financing”). The Equipment Financing contains customary terms and events of default and provides for thirty-six monthly payments with an implicit interest rate of 6.25%, maturing on May 1, 2022. Upon maturity, the equipment will revert back to the Intermediate Partnership.
Other. We also have an agreement with a bank to provide additional letters of credit in an amount of $5.0 million to maintain surety bonds to secure certain asset retirement obligations and our obligations for workers' compensation benefits. At June 30, 2019, we had $5.0 million in letters of credit outstanding under this agreement.
