We must pay a commitment fee of 0.20% to 0.35% per annum on the average daily unused portion of the aggregate unused revolving commitments under the Credit Agreement. We must also pay fees as specified in the Fee Letter (as defined in the Credit Agreement) and with respect to any letters of credit issued under the Credit Agreement.
The Credit Agreement contains usual and customary negative covenants for agreements of this type, including, but not limited to, restrictions on our ability to, subject to certain exceptions, create, incur or assume indebtedness; create, incur, assume or suffer to exist liens; make certain investments; allow our subsidiaries to merge or consolidate with another entity; make certain asset dispositions; pay certain dividends or other distributions to shareholders; enter into transactions with affiliates; enter into sale leaseback transactions; and exceed the limits on annual capital expenditures. The Credit Agreement also requires us to satisfy certain financial covenants, including a minimum interest coverage ratio of 3.00 to 1.00. At March 31, 2024, our interest coverage ratio was 4.87 to 1.00. The Credit Agreement also requires us to maintain a consolidated total leverage ratio not to exceed 4.00 to 1.00 (which was increased as of July 1, 2023 from 3.50 to 1.00 in connection with the acquisition of MSA). As of March 31, 2024, our consolidated total leverage ratio was 1.98 to 1.00.
The Credit Agreement includes customary events of default, including, among other things, payment default, covenant default, breach of representation or warranty, bankruptcy, cross-default, material ERISA events, material money judgments, and failure to maintain subsidiary guarantees. If an event of default occurs, the Agent will be entitled to take various actions, including the acceleration of amounts due under the Credit Agreement, termination of the credit facility, and all other actions permitted to be taken by a secured creditor.
Other Debt
With the consummation of the MSA acquisition, the Company assumed a Fond du Lac County and Fond du Lac Economic Development Corporation term note (Fond du Lac Term Note). The Fond du Lac Term Note is secured by a security agreement, payable in annual installments of $500 plus interest at 2.00% and is due in full in December 2028. The balance outstanding as of March 31, 2024 was $2,735, with the short-term and long-term balance of $500 and $1,875, respectively, recorded in other current liabilities and other long-term liabilities in the Condensed Consolidated Balance Sheets.
Capital Requirements and Sources of Liquidity
During the three months ended March 31, 2024 and 2023, our capital expenditures were $2,775 and $2,408 respectively. The increase of $367 was driven by continued investments in technology and automation. Capital expenditures for the full year 2024 are expected to be between $15,000 and $20,000.
We have historically relied upon cash available through credit facilities, in addition to cash from operations, to finance our working capital requirements and to support our growth. At March 31, 2024, we had immediate availability of $110,183 through our revolving credit facility and the availability of incremental facilities to the greater of $100,000 and 125% of the Company’s twelve month trailing Consolidated EBITDA through an accordion feature under our Credit Agreement, subject to the covenants under the Credit Agreement. We regularly monitor potential capital sources, including equity and debt financings, in an effort to meet our planned capital expenditures and liquidity requirements. Our future success will be highly dependent on our ability to access outside sources of capital. We will continue to have access to the availability currently provided under the Credit Agreement as long as we remain compliant with the financial covenants. Based on our estimates at this time, we expect to be in compliance with these financial covenants through 2024 and the foreseeable future.
We believe that our operating cash flow and available borrowings under the Credit Agreement are sufficient to fund our operations for 2024 and beyond. However, future cash flows are subject to a number of variables, and additional capital expenditures will be required to conduct our operations. There can be no assurance that operations and other capital resources will provide cash in sufficient amounts to maintain planned or future levels of capital expenditures. In the event we make one or more acquisitions and the amount of capital required is greater than the amount we have available for acquisitions at that time, we could be required to reduce the expected level of capital expenditures and/or seek additional capital. If we seek additional capital, we may do so through borrowings under the Credit Agreement, joint ventures, asset sales, offerings of debt or equity securities or other means. We cannot guarantee that this additional capital will be available on acceptable terms or at all. If we are unable to obtain the funds we need, we may not be able to complete acquisitions that may be favorable to us or finance the capital expenditures necessary to conduct our operations.
