(1The discount rates are specific for individual leases primarily based on the lease term. The range of discount rates used to calculate the present value of the operating lease payments is 0.94% to 6.42% and for finance lease payments is 1.14% to 6.21%. The weighted average discount rate was derived from estimated incremental borrowing rates based on our credit quality, as we did not have any borrowings at the balance sheet date with comparable terms to our lease agreements. At December 31, 2023, the weighted average discount rate for operating leases is 3.66% and the weighted average remaining lease term is 23.1 years. At December 31, 2023, the weighted average discount rate for finance leases is 3.47% and the weighted average remaining lease term is 22.6 years.
