Interest rate description |  | At the Company’s election, borrowings under the 2023 Revolving Credit Facility bear interest at either: (1) a base rate plus a margin of 0.125% to 0.875%, depending on the Company’s Leverage Ratio (as such term is defined in the 2023 Credit Agreement), or (2) a rate equal to the secured overnight financing rate as administered by the Federal Reserve Bank of New York for the applicable tenor plus 0.10% (“Adjusted Term SOFR”) plus a margin of 1.125% to 1.875%, depending on the Company’s Leverage Ratio. The base rate is determined by the greater of: (a) the prime commercial lending rate announced by Bank of Montreal from time to time, (b) the federal funds effective rate, plus 1/2 of 1.00%, (c) Adjusted Term SOFR for a one-month tenor, plus 1.00%, or (d) 0.00%. |
