The Company has a revolving Credit Agreement with Bank of America and four other lenders which provides for a line of credit of up to $100.0 million, including a $35.0 million letter of credit subfacility, and a $35.0 million swingline subfacility. The facility contains customary terms and conditions, including restrictions on indebtedness, dividend payments, business combinations and other related items. The revolving credit facility includes a full and unconditional guarantee by the Company's 100 percent owned domestic subsidiaries whose assets equal substantially all of the consolidated assets of the Company and its subsidiaries.

During the second quarter of 2022, the Company entered into Amendment No. 6 to Credit Agreement (the “Amendment”). This Amendment (1) extends the termination date for revolving loans from July 26, 2023 to June 22, 2027, (2) replaces LIBOR with the Term SOFR as an interest rate option in connection with revolving loan borrowings and reduces the applicable rate margins by approximately 25.0 basis points at each pricing level, (3) introduces a 1.00% per annum floor for Base Rate borrowings, and (4) permits the issuance of letters of credit in currencies other than U.S. dollars.

The Credit Agreement has three financial covenants when RPC’s trailing four quarter EBITDA (as calculated under the Credit Agreement) is equal to or greater than $50.0 million: (i) the consolidated leverage ratio cannot exceed 2.50:1.00 and (ii) the debt service coverage ratio must be equal to or greater than 2.00:1.00; otherwise, the minimum tangible net worth must be greater than or equal to $400.0 million.

Revolving loans under the amended revolving credit facility bear interest at one of the following two rates at the Company’s election:

In addition, the Company pays an annual fee ranging from 0.20% to 0.30%, based on a quarterly consolidated leverage ratio calculation, on the unused portion of the credit facility.

The Company has incurred total loan origination fees and other debt related costs associated with this revolving credit facility in the aggregate of approximately $3.7 million. These costs are being amortized to interest expense over the remaining term of the loan, and the remaining unamortized balance of $400 thousand at June 30, 2022 is classified as part of non-current Other assets.

As of June 30, 2022, RPC had no outstanding borrowings under the revolving credit facility, and letters of credit outstanding relating to self-insurance programs and contract bids totaled $16.3 million; therefore, a total of $83.7 million of the facility was available. Interest incurred, which includes facility fees on the unused portion of the revolving credit facility and the amortization of loan costs, and interest paid on the credit facility were as follows for the periods indicated:
