[1] On May 31, 2019, the Company and certain of its U.S. subsidiaries entered into a Second Amended and Restated Credit Agreement (the “2019 Credit Agreement”) with JPMorgan Chase Bank, N.A. as administrative agent, and a group of lenders. The 2019 Credit Agreement amended and restated the Company’s existing amended and restated credit agreement dated as of December 23, 2016 to, among other modifications: (i) increase the amount of the outstanding term loan (“Term Loan”) from approximately $97 million to $100 million, (ii) extend the maturity date of the outstanding Term Loan and the revolving credit facility (“Revolver”) by approximately 29 months to May 31, 2024, and (iii) decrease the applicable interest rate margins for LIBOR and base rate loans by 25 basis points. The Term Loan is payable in 19 quarterly installments of principal and interest beginning on September 29, 2019, with escalating principal payments, at the rate of 5.0% per annum for the first eight payments, and 10.0% per annum for the remaining 11 payments, with the remaining balance of $62.5 million due upon maturity. The Revolver, in the aggregate amount of $200 million, subject to seasonal reduction to an aggregate amount of $100 million for the period from January 1 through August 1, may be used for working capital and general corporate purposes, subject to certain restrictions. For each borrowing under the 2019 Credit Agreement, the Company may elect that such borrowing bear interest at an annual rate equal to either: (1) a base rate plus an applicable margin varying based on the Company’s consolidated leverage ratio, where the base rate is the highest of (a) the prime rate, (b) the New York fed bank rate plus 0.5%, and (c) a LIBOR rate plus 1%, or (2) an adjusted LIBOR rate plus an applicable margin varying based on the Company’s consolidated leverage ratio.
