Letters of credit outstanding (in US dollars)			$ 130,900,000	$ 71,300,000
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) 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”) (5.34% at June 30, 2023) plus a margin of 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 (8.25% at June 30, 2023), (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%. The interest rates in effect at June 30, 2023 and December 31, 2022 were 6.34% and 5.73%, respectively. 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 June 30, 2023 and December 31, 2022. 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.
