Borrowings under the Credit Agreement bear interest at a fluctuating LIBOR (which may be adjusted for certain reserve requirements), plus 1.00% to 2.00% depending on the current Consolidated Total Leverage Ratio (as defined in the Credit Agreement). Under certain circumstances, we may not be able to pay interest based on LIBOR. If that happens, we will be required to pay interest at the Base Rate, which is the sum of (a) the higher of (i) the Prime Rate (as publicly announced by the Agent from time to time) and (ii) the Federal Funds Rate plus 0.50%, plus (b) 0.00% to 1.00%, depending on the current Total Consolidated Leverage Ratio. The Credit Agreement also includes provisions for determining a replacement rate when LIBOR is no longer available.
At March 31, 2022, the interest rate on outstanding borrowings under the Revolving Loan was 1.75%. At March 31, 2022, we had availability of $116,670 under the Revolving Loan.
We must pay a commitment fee at a rate of 0.20% 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 or incur liens, make certain investments, merge or consolidate with another entity, make certain asset dispositions, pay dividends or other distributions to shareholders, enter into transactions with affiliates, enter into sale leaseback transactions or make 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, 2022, our interest coverage ratio was 19.13 to 1.00. The Credit Agreement also requires us to maintain a consolidated total leverage ratio not to exceed 3.25 to 1.00, although such leverage ratio can be increased in connection with certain acquisitions. As of March 31, 2022, our consolidated total leverage ratio was 1.81 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.
On June 30, 2020, March 31, 2021 and March 31, 2022, the Company entered into amendments to the Credit Agreement. Please refer to Note 3 – Bank Revolving Credit Notes in the Notes to the Consolidated Financial Statements for a more detailed discussion.
Capital Requirements and Sources of Liquidity
During the three months ended March 31, 2022 and 2021, our capital expenditures were $12,979 and $5,559, respectively. The increase of $7,420 was driven by our ongoing investment in new technology and automation along with the repurposing of assets in the Company’s Hazel Park, MI facility, which is expected to continue through 2022. Capital expenditures for the full year 2022 are expected to be between $55,000 and $65,000.
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, 2022, we had immediate availability of $116,670 through our Revolving Loan and another $100,000 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 of the impact of the COVID-19 pandemic at this time, we expect to be in compliance with these financial covenants through 2022 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 2022 and beyond when taking into consideration the estimated impacts of the pandemic based on the information we have available at this time. 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
