The Company leases railcars, real estate, and certain equipment under operating and, to a lesser extent, finance lease arrangements. As of and for the twelve months ended August 31, 2023, 2022, and 2021, finance leases were not a material component of the Company's lease portfolio. The Company’s real estate and equipment leases have remaining lease terms ranging from less than one year to 75 years, with some including options to extend up to 8 years. The Company recognizes a lease liability and corresponding right-of-use (ROU) asset based on the present value of lease payments. To determine the present value of lease payments, as most of its leases do not provide a readily determinable implicit rate, the Company’s incremental borrowing rate is used to discount the lease payments based on information available at the lease commencement date. The Company gives consideration to its recent debt issuances as well as publicly available data for instruments with similar characteristics when estimating its incremental borrowing rate.
