The Company leases commercial and industrial space to tenants primarily under non-cancelable operating leases that generally contain provisions for minimum base rents plus reimbursement for certain operating expenses. Total minimum lease payments are recognized in rental income on a straight-line basis over the term of the related lease and estimated reimbursements from tenants for real estate taxes, insurance, common area maintenance and other recoverable operating expenses are recognized in rental income in the period that the expenses are incurred.

The Company recognized $378.3 million, $314.1 million and $291.4 million of lease income related to operating lease payments for the year ended December 31, 2021, 2020 and 2019, respectively.

The Company's current leases have expirations ranging from 2022 to 2044. The following table sets forth the undiscounted cash flows for future minimum base rents to be received under operating leases as of December 31, 2021.

	As of December 31, 2021
2022	$	380,040
2023	372,142
2024	331,657
2025	289,267
2026	264,413
Thereafter	1,012,429
Total	$	2,649,948

The future minimum base rents in the table above excludes tenant reimbursements of operating expenses, amortization of adjustments for deferred rent receivables and the amortization of above/below-market lease intangibles.

Certain of the Company’s real estate are subject to ground leases. The Company’s ground leases are classified as either operating leases or financing leases based on the characteristics of each lease. As of December 31, 2021, the Company had five ground leases classified as operating and two ground leases classified as financing. Each of the Company’s ground leases were acquired as part of the acquisition of real estate and no incremental costs were incurred for such ground leases. The Company’s ground leases are non-cancelable, and contain no renewal options. The Company's Chicago office space lease has a remaining lease term of approximately four years and no option to renew.

The Company incurred operating lease costs of approximately $3.7 million for the years ended December 31, 2021 and 2020 respectively, which are included in "Property Operating Expense" in the accompanying consolidated statement of

operations. Total cash paid for amounts included in the measurement of operating lease liabilities was $1.6 million for the years ended December 31, 2021 and 2020, respectively.

The following table sets forth the weighted-average for the lease term and the discount rate as of December 31, 2021 and 2020:

	As of December 31,
Lease Term and Discount Rate	2021		2020
Weighted-average remaining lease term in years	73.7		80.1
Weighted-average discount rate (1)	4.83	%	4.98	%

(1) Because the rate implicit in each of the Company's leases was not readily determinable, the Company used an incremental borrowing rate. In determining the Company's incremental borrowing rate for each lease, the Company considered recent rates on secured borrowings, observable risk-free interest rates and credit spreads correlating to the Company's creditworthiness, the impact of collateralization and the term of each of the Company's lease agreements.

Maturities of lease liabilities as of December 31, 2021 were as follows:

	As of December 31, 2021
	Operating		Financing
2022	$	1,730	$	591
2023	1,796		355
2024	1,831		360
2025	1,783		370
2026	1,716		375
Thereafter	284,459		3,820
Total undiscounted lease payments	293,315		5,871
Less imputed interest	(246,085)		(2,205)
Total lease liabilities	$	47,230	$	3,666
