The Company enters into leases in the normal course of business primarily for its banking facilities and branches. The Company’s operating leases have varying maturity dates through year end 2042, some of which include renewal or termination options to extend the lease. In addition, the Company leases or subleases real estate to third parties. The Company includes lease extension and termination options in the lease term if, after considering relevant economic factors, it is reasonably certain the Company will exercise the option. In addition, the Company has elected to account for any non-lease components in its real estate leases as part of the associated lease component. The Company has also elected not to recognize leases with original lease terms of 12 months or less (short-term leases) on the Company’s balance sheet.

Leases are classified at the lease commencement date. Lease expense for operating leases and short-term leases is recognized on a straight-line basis over the lease term. Right-of-use assets represent our right to use an underlying asset for the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Right-of-use assets and lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term.

The following table summarizes the amount and balance sheet line item for our operating lease right-of-use asset and liability as of September 30, 2021:


	Balance Sheet Line Item	September 30, 2021
Operating lease right-of-use asset	Accrued interest receivable and other assets	$	11,580
Operating lease liability	Accrued interest payable and other liabilities		13,744

The Company uses its incremental borrowing rate at lease commencement to calculate the present value of lease payments when the rate implicit in a lease is not known. The Company’s incremental borrowing rate is based on the FHLB regular advance rate, adjusted for the lease term and other factors. At September 30, 2021, the weighted-average discount rate of operating leases was 0.85% and the weighted average remaining life of operating leases was 6.0 years.

The future minimum lease payments for operating leases, subsequent to September 30, 2021, as recorded on the balance sheet, are summarized as follows:


	Operating Lease Commitments
2021	$	1,515
2022		3,618
2023		2,412
2024		2,194
2025		1,505
Thereafter		3,108
