Leases

12 Months Ended

Dec. 31, 2022

We are a lessor of medical office and life science properties, senior living communities and other healthcare related properties. Our leases provide our tenants with the contractual right to use and economically benefit from all of the premises demised under the leases; therefore, we have determined to evaluate our leases as lease arrangements.

Our leases provide for base rent payments and, in addition, may include variable payments. Rental income from operating leases, including any 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. Some of our leases have options to extend or terminate the lease exercisable at the option of our tenants, which are considered when determining the lease term.

We increased rental income to record revenue on a straight line basis by $8,916, $5,846 and $6,069 for the years ended December 31, 2022, 2021 and 2020, respectively. Rents receivable, excluding receivables related to our properties classified as held for sale, if any, include $76,363 and $82,131 of straight line rent receivables at December 31, 2022 and 2021, respectively, and are included in other assets, net in our consolidated balance sheets.

We do not include in our measurement of our lease receivables certain variable payments, including 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 $47,669, $74,860 and $77,599 for the years ended December 31, 2022, 2021 and 2020, respectively, of which tenant reimbursements totaled $44,470, $72,690 and $75,378, respectively.

The following table presents our operating lease maturity analysis, excluding lease payments from properties classified as held for sale, if any, as of December 31, 2022:

Right of Use Asset and Lease Liability. For leases where we are the lessee, we recognized a right of use asset and a lease liability equal to the present value of the minimum lease payments with rental payments being applied to the lease liability and the right of use asset being amortized over the term of the lease. The values of the right of use assets and related liabilities representing our future obligation under the respective lease arrangements for which we are the lessee were $26,508 and $26,889, respectively, as of December 31, 2022, and $4,153 and $4,352, respectively, as of December 31, 2021. The right of use assets and related lease liabilities are included within other assets, net and other liabilities, respectively, within our consolidated balance sheets. In addition, we lease equipment at certain of our managed senior living communities. These leases are short term in nature, are cancelable with no fee or do not result in an annual expense in excess of our capitalization policy and, as a result, are not recorded on our consolidated balance sheets.
