We lease our real estate properties to customers under agreements that are classified primarily as operating leases. We recognize the total minimum lease payments provided for under the leases on a straight-line basis over the lease term. Our weighted average lease term remaining was 55 months based on square feet for all leases in effect at December 31, 2022.

The following table summarizes the minimum lease payments due from our customers on leases for space in our operating properties, prestabilized and under development properties, other real estate investments and assets held for sale or contribution at December 31, 2022 (in thousands):


2023	$	4,404,367
2024		4,221,731
2025		3,800,708
2026		3,231,191
2027		2,578,599
Thereafter		9,452,245

These amounts do not reflect future rental revenue from the renewal or replacement of existing leases and exclude reimbursements of operating expenses along with rental increases that are not fixed.

We had approximately 135 and 120 land and office space leases in which we were the lessee at December 31, 2022 and 2021, respectively, which primarily qualify as operating leases with remaining lease terms of 1 to 87 years at December 31, 2022. Our lease liabilities were $638.8 million and $448.4 million at December 31, 2022 and 2021, respectively.

The following table summarizes the fixed, future minimum rental payments, excluding variable costs, for leases that had commenced at December 31, 2022, with amounts discounted at lease commencement by our incremental borrowing rates to calculate the lease liabilities of our leases (in thousands):


2023	$	62,061
2024		71,709
2025		56,349
2026		47,443
2027		39,642
Thereafter		1,144,025
Total undiscounted rental payments		1,421,229
Less imputed interest		782,418
Total lease liabilities	$	638,811

The weighted average remaining lease term for these leases was 31 and 28 years at December 31, 2022 and 2021, respectively. We do not include renewal options in the lease term for calculating the lease liability unless we are reasonably certain we will exercise the option or the lessor has the sole ability to exercise the option. The weighted average discount rate was 3.4% and 3.2% at December 31, 2022 and 2021, respectively. We assigned a collateralized interest rate to each lease based on the term of the lease and the currency in which the lease was denominated.
