to 1.10:1.00, then the LIBOR Rate plus 2.00%; (B) if a Base Rate Loan, at a per annum rate equal to the Base Rate plus the Base Rate Margin of 1.25% per annum until the March 31, 2021 financial statements were delivered and thereafter (i) if the Fixed Charge Coverage Ratio is less than 1.10:1.00, then the Base Rate of 1.25% or (ii) if the Fixed Charge Coverage Ratio is greater than or equal to 1.10:1.00, then the Base Rate plus 1.00%. The Credit Agreement contains a LIBOR floor of 0.25% so that if the LIBOR Rate is below 0.25%, then the LIBOR Rate will be deemed to be equal to 0.25% for purposes of the Credit Agreement.
The Company is required to pay a monthly Unused Line Fee on the average daily unused portion of the 2020 Revolving Credit Facility, at a per annum rate equal to 0.25%.
Pursuant to Amendment No. 1 to Credit Agreement dated July 12, 2021 (the “Amendment”), between Tessco and Wells, Wells agreed to a 25 basis point reduction in certain otherwise applicable rates and fees over an agreed period, as set forth in the Amendment. The Amendment also included certain changes related to the transition away from the use of LIBOR as a rate option, and is expected to simplify day-to-day management of the 2020 Revolving Credit Facility. It is anticipated that, so long as no event of default occurs, the interest rate applicable to borrowings under the 2020 Revolving Credit Facility will be lower than it otherwise would have been, going forward, until the end of the agreed period. On September 26, 2021, the interest rate applicable to borrowings under the secured 2020 Revolving Credit Facility was 2.09%, which includes the 25 basis point reduction included in the Amendment as discussed above.
Following an Event of Default, the Lenders’ may at their option increase the applicable per annum rate to a rate equal to 2 percentage points above the otherwise applicable rate and with certain events of default, such increase is automatic. In addition, the 25 basis point reduction, insofar as then otherwise available under the Amendment, will terminate, and at the written election of the Agent or the Required Lenders at any time while an Event of Default exists, the Company will no longer have the option to request that revolving loans be based on the LIBOR Rate.
The Credit Agreement contains 1 financial covenant, a Fixed Charge Coverage Ratio, which is tested only if Excess Availability (generally, borrowing availability less the aggregate of trade payables and book overdrafts, each in excess of historical amounts) is less than the greater of (a) 16.7% of the maximum amount of the Credit Facility (at closing, $12,525,000) and (b) $12,500,000. In addition, the Credit Agreement contains provisions that could limit our ability to engage in specified transactions or activities, including (but not limited to) investments and acquisitions, sales of assets, payment of dividends, issuance of additional debt and other matters.
Borrowings under the 2020 Revolving Credit Facility were initially used to pay all indebtedness outstanding under the previously existing credit facility among the Company and certain subsidiaries, the lenders party thereto and Truist Bank (successor by merger to SunTrust Bank), as administrative agent, and may be used for working capital and other general corporate purposes, and as further provided in, and subject to the applicable terms of, the Credit Agreement. As of September 26, 2021, borrowings under the secured 2020 Revolving Credit Facility totaled $45.7 million and, therefore, the Company had $29.3 million available for borrowing as of September 26, 2021, subject to the Borrowing Base limitation and compliance with the other applicable terms referenced above.
The Company is required to make certain prepayments under the 2020 Revolving Credit Facility under certain circumstances, including from net cash proceeds from certain asset dispositions in excess of certain thresholds.
