Credit agreement, covenant description | the Credit Agreement contains two: namely, borrowers are required to maintain a Total Leverage (“TL”) Ratio of no more than 3.5-to-1, during the first three years, stepping down to 3.25-to-1 for periods subsequent to September 30, 2024, and a Fixed Charge Coverage Ratio ("FCCR") of at least 1.25-to-1. In addition, to the extent that it completes acquisitions totaling $15 million or more in any 90-day period, AMVAC may step-up the TL Ratio by 0.5-to-1, not to exceed 4.00-to-1, for the next three full consecutive quarters. |

Senior secured credit facility, maturity date | Aug. 05, 2026 |
Credit agreement, variable rate description | Under the Credit Agreement, revolving loans bear interest at a variable rate based, at borrower’s election with proper notice, on either (i) LIBOR plus the “Applicable Margin” which is based upon the Total Leverage (“TL”) Ratio (“LIBOR Revolver Loan”) or (ii) the greater of (x) the Prime Rate, (y) the Federal Funds Rate plus 0.5%, and (z) the Daily One-Month LIBOR Rate plus 1.00%, plus, in the case of (x), (y) or (z) the Applicable Margin (“Adjusted Base Rate Revolver Loan”). The Company and the Lenders entered into an amendment to the Credit Agreement, effective March 9, 2023, whereby LIBOR was replaced by SOFR with a credit spread adjustment of 10.0 bps for all SOFR periods. The revolving loans now bear interest at a variable rate based at our election with proper notice, on either (i) SOFR plus 0.1% per annum and the “Applicable Margin” or (ii) the greater of (x) the Prime Rate, (y) the Federal Funds Rate plus 0.5%, and (z) the Daily One-Month SOFR Rate plus 1.10%, plus, in the case of (x), (y) or (z), the Applicable Margin (“Adjusted Base Rate Revolver Loan”). Interest payments for SOFR Revolver Loans are payable on the last day of each interest period (either one-, three- or six- months, as selected by the Company) |
