Interest rate description   At the Company’s election, borrowings under the 2020 Credit Agreement bear interest at either: (1) a base rate plus a margin of 0.00% to 0.75%, based on certain financial tests, or (2) United States dollar LIBOR (0.10% at December 31, 2021) plus 1.00% to 1.75%, based on certain financial tests. The base rate is determined by the greater of (a) the prime commercial lending rate announced by Bank of Montreal from time to time (3.25% at December 31, 2021), (b) the federal funds effective rate, plus 1/2 of 1.00%, (c) the daily one month LIBOR rate, plus 1.00%, or (d) 0.00%. The interest rate in effect at December 31, 2021 was 1.10%. A commitment fee is payable on the average daily unused amount of the 2020 Revolving Credit Facility, which ranges from 0.10% to 0.25%, based on certain financial tests. The fee was 0.10% of the unused amount as of December 31, 2021. Fees for letters of credit issued under the 2020 Revolving Credit Facility range from 0.75% to 1.75% of the respective face amounts of outstanding letters of credit, depending on the nature of the letter of credit, and are computed based on certain financial tests.
