In connection with the Credit Agreement, AstroNova entered into certain hedging arrangements with the Lender to manage the variable interest rate risk and currency risk associated with its payments in respect of the term loan. Under these arrangements, payments of principal and interest in respect of approximately $8.9 million of the principal of the term loan will be made in Danish Krone, and interest on such principal amount will be payable at a fixed rate of 0.67% per annum for the entire term, subject only to potential increases of 0.25% or 0.50% per annum based on the Company’s consolidated leverage ratio. The obligations of ANI ApS under these arrangements are guaranteed by the Company.
