DEBT	NOTE 4—DEBT Revolving Credit Facility and Term Loan—On November 2, 2018, we entered into a Credit and Security Agreement (as amended, the “Revolving Credit Facility”) with KeyBank National Association (“KeyBank”). The Revolving Credit Facility was amended on February 20, 2020 and consists of a $10.0 million term loan (the “Term Loan”) and up to $30.0 million revolving line of credit, including $3.0 million letter of credit availability. All personal property assets, including, but not limited to accounts receivable, coal inventory and certain mining equipment are pledged to secure the Revolving Credit Facility. The Revolving Credit Facility has a maturity date of December 31, 2023 and bears interest based on LIBOR + 2.0% or Base Rate + 1.5%. Base Rate is the highest of (i) KeyBank’s prime rate, (ii) Federal Funds Effective Rate + 0.5%, or (iii) LIBOR + 2.0%.

The Term Loan is secured under a Master Security Agreement with a pledge of certain underground and surface mining equipment, bears interest at LIBOR + 5.15% and is required to be repaid in monthly installments of $278 thousand including accrued interest. The outstanding principal balance of the Term Loan was $8.3 million at June 30, 2020. The Revolving Credit Facility contains usual and customary covenants including limitations on liens, additional indebtedness, investments, restricted payments, asset sales, mergers, affiliate transactions and other customary limitations, as well as financial covenants. As of June 30, 2020, we were in compliance with all debt covenants. Equipment Financing Loan—On April 16, 2020, we entered into an equipment loan with Key Equipment Finance, a division of KeyBank, as lender, in the principal amount of approximately $4.7 million for the financing of existing underground and surface equipment (the “Equipment Financing Loan”). The loan bears interest at 7.45% per annum and is payable in 36 monthly installments of $147 thousand. There is a 3% premium for prepayment of the loan within the first 12 months. This premium declines by 1% during each successive 12-month period. The outstanding principal balance of the Equipment Financing Loan was $4.5 million at June 30, 2020.
