Leases [Abstract]

Leases

LeasesRental income from operating leases, including payments derived by index or market-based indices, is recognized on a straight line basis over the lease term when we have determined that the collectability of substantially all of the lease payments is probable. We increased rental income by $10,830, $15,368 and $16,079 to record revenue on a straight line basis during the

years ended December 31, 2022, 2021 and 2020, respectively. Rents receivable, excluding properties classified as held for sale, include $86,305 and $82,978 of straight line rent receivables at December 31, 2022 and 2021, respectively.

We do not include in our measurement of our lease receivables certain variable payments, including payments determined by changes in the index or market-based indices after the inception of the lease, certain tenant reimbursements and other income until the specific events that trigger the variable payments have occurred. Such payments totaled $83,103, $85,107 and $75,851 for the years ended December 31, 2022, 2021 and 2020, respectively, of which tenant reimbursements totaled $78,388, $81,295 and $71,385, respectively.

The following operating lease maturity analysis presents the future contractual lease payments to be received by us through 2053 as of December 31, 2022:

Year	Amount
2023	$	393,318
2024	358,254
2025	313,267
2026	279,820
2027	248,976
Thereafter	1,393,682
Total	$	2,987,317

As of December 31, 2022, tenants representing approximately 1.5% of our total operating lease maturities had exercisable rights to terminate their leases before the stated terms of their leases expire. In 2023, 2024, 2025, 2026, 2027, 2028, 2029, 2030, 2031, 2035, 2037 and 2040, early termination rights become exercisable by other tenants who represented an additional approximately 1.3%, 2.4%, 5.6%, 1.6%, 1.6%, 5.5%, 2.1%, 1.6%, 0.3%, 3.5%, 0.4% and 1.7% of our total operating lease maturities, respectively. In certain circumstances, some leases provide the tenant with the right to terminate if the legislature or other funding authority does not appropriate the funding necessary for the tenant to meet its lease obligations; we have determined the fixed non-cancelable lease term of these leases to be the full term of the lease because we believe the occurrence of early terminations to be a remote contingency based on both our historical experience and our assessments of the likelihood of lease cancellation on a separate lease basis. As of December 31, 2022, 10 of our tenants had the right to terminate their leases if the respective legislature or other funding authority does not appropriate the funding necessary for the tenant to meet its obligation. These 10 tenants represented approximately 4.8% of our total operating lease maturities as of December 31, 2022.

Leases where we are the lessee. We had one lease where we were the lessee which expired on January 31, 2021. We subleased a portion of the space, which sublease also expired on January 31, 2021. Rent expense incurred under the lease, net of sublease revenue, was $79 and $1,749 for the years ended December 31, 2021 and 2020, respectively.
