The Company leases railcars, real estate, and certain equipment under operating and, to a lesser extent, finance lease arrangements. As of and for the three and six months ended February 28, 2023 and February 28, 2022, 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 76 years, with some including options to extend up to 15 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 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.
