The additional amount was amortized as interest expense over the term of the Term Loan Facility. On April 1, 2021, we elected to pay in-kind the $2.8 million, interest payment due under our Term Loan, which increased our Term Loan balance accordingly. In September 2021, we amended our Term Loan Credit Agreement and elected to pay in-kind the $3.1 million October 1, 2021 interest payment which reduced the amount of the Term Loan Accordion by the PIK amount. On December 30, 2021, we amended our Term Loan Credit Agreement and elected to pay in-kind the $3.2 million January 3, 2022 interest payment which reduced the Term Loan Accordion by a corresponding amount.
Revolving ABL Credit Facility
On October 1, 2018, we entered into a $40.0 million revolving Credit Agreement (the “Revolving ABL Credit Facility”), including availability for letters of credit in an aggregate amount at any time outstanding not to exceed $7.5 million. Availability under the Revolving ABL Credit Facility is subject to a borrowing base calculated based on 85% of the net amount of our eligible accounts receivable, minus reserves. The ABL Credit Facility has a maturity date of October 1, 2023.
At our election, interest under the Revolving ABL Credit Facility is determined by reference at our option to either (i) a “base rate” equal to the higher of (a) the federal funds effective rate plus 0.05%, (b) LIBOR with an interest period of one month, plus 1.0%, and (c) the prime rate of Wells Fargo, plus in each case, an applicable base rate margin ranging from 1.0% to 1.5% based on quarterly availability, or (ii) a revolving loan rate equal to LIBOR for the applicable interest period plus an applicable LIBOR margin ranging from 2.0% to 2.5% based on quarterly availability. We also pay, on a quarterly basis, a commitment fee of 0.375% (or 0.25% at any time when revolver usage is greater than 50% of the maximum credit) per annum on the unused portion of the Revolving ABL Credit Facility commitment.
The Revolving ABL Credit Facility contains a springing fixed charge coverage ratio covenant of 1.00 to 1.00 that is tested when availability is less than 10% of the maximum credit. The Revolving ABL Credit Facility also contains other customary affirmative and negative covenants, including limitations on indebtedness, liens, fundamental changes, asset dispositions, restricted payments, investments and transactions with affiliates. The Revolving ABL Credit Facility also provides for customary events of default, including breaches of material covenants, defaults under the Term Loan Agreement or other material agreements for indebtedness, and a change of control. We are in compliance with our financial covenants as of June 30, 2022.
The obligations under the Revolving ABL Credit Facility are secured by a first priority lien on Priority Collateral, which includes all accounts receivable and deposit accounts, and a second priority lien on the Term Priority Collateral, and are unconditionally guaranteed by all of our current and future direct and indirect subsidiaries. As of June 30, 2022, the weighted-average interest rate on our borrowings was 14.59%. At June 30, 2022, the borrowing base under our Revolving ABL Credit Facility was $22.0 million, and we had $14.0 million of availability remaining of our $40.0 million commitment on that date.
On March 18, 2022, we entered into a third amendment to that certain Credit Agreement, dated as of October 1, 2018 (the “Third Amendment to the Credit Agreement”), by and among us, Sidewinder Drilling LLC (“Sidewinder”), the Lenders named therein and Wells Fargo Bank, National Association (“Wells Fargo”), as administrative agent. The Third Amendment to the Credit Agreement amends the original credit agreement, dated as of October 1, 2018 (the “Credit Agreement”) by deleting references to the “Term Loan Agreement” and related definitions and adding certain references and clauses related to our placement of $157.5 million aggregate principal amount of convertible secured PIK toggle notes due 2026 (the “Convertible Notes”), which were issued pursuant to an Indenture, dated as of March 18, 2022 (the “Indenture”), with U.S. Bank Trust Company, National Association as trustee and collateral agent.
Additionally, included in our long-term debt are finance leases. These leases generally have initial terms of 36 months and are paid monthly.
