We adopted the lease standard ASC 842 on January 1, 2019 and applied it to leases that were in place on the effective date as both a lessor and lessee. Our results for reporting periods beginning January 1, 2019 are presented under the ASC 842 lease standard. We adopted ASC 842 effective January 1, 2019 under the modified retrospective approach and elected the optional transition method to apply the provisions of ASC 842 as of the adoption date, rather than the earliest period presented. We elected to apply certain adoption related practical expedients for all leases that commenced prior to the election date. This practical expedient allowed us to not separate expenses reimbursed by our customers (“tenant reimbursements”) from the associated rental revenue if certain criteria were met.

We lease most of our operating properties to customers under agreements that are typically classified as operating leases (as noted below, two of our leases are accounted for as financing arrangements effective on December 31, 2021). We recognize the total minimum lease payments provided for under the operating leases on a straight-line basis over the lease term. Generally, under the terms of our leases, the majority of our rental expenses, including common area maintenance, real estate taxes and insurance, are recovered from our customers. We record amounts reimbursed by customers in the period that the applicable expenses are incurred, which is generally ratably throughout the term of the lease. We have elected the package of practical expedients that allows lessors to not separate lease and non-lease components by class of underlying asset. This practical expedient allowed us to not separate expenses reimbursed by our customers (“tenant reimbursements”) from the associated rental revenue if certain criteria were met. We assessed these criteria and concluded that the timing and pattern of transfer for rental revenue and the associated tenant reimbursements are the same, and for the leases that qualify as operating leases, we accounted for and presented rental revenue and tenant reimbursements as a single component under Lease revenue in our consolidated statements of income for the three and nine months ended September 30, 2022 and 2021.

On December 31, 2021, as a result of the asset purchase and sale transaction with UHS, as amended during the first quarter of 2022, the real estate assets of two wholly-owned subsidiaries of UHS were transferred to us (Aiken and Canyon Creek). As discussed in Note 2, these assets are accounted for as financing arrangements and our consolidated balance sheets at September 30, 2022 and December 31, 2021 reflect financing receivables related to this transaction amounting to $83.7 million and $82.4 million, respectively. Pursuant to the leases, as amended during the first quarter of 2022, the aggregate annual rental during 2022 on the acquired properties, which is payable to us on a monthly basis, amounts to approximately $5.7 million ($3.9 million related to Aiken and $1.8 million related to Canyon Creek). The portion of these lease payments that will be included in our consolidated statements of income, and reflected as interest income on financing leases, is expected to be approximately $5.5 million during the full year of 2022. Lease revenue will not be impacted by the lease payments received related to these two properties.

The components of the “Lease revenue – UHS facilities” and “Lease revenue – Non-related parties” captions for the three and nine month periods ended September 30, 2022 and 2021 are disaggregated below (in thousands). Base rents are primarily stated rent amounts provided for under the leases that are recognized on a straight-line basis over the term of the lease. Bonus rents and tenant reimbursements represent amounts where tenants are contractually obligated to pay an amount that is variable in nature.

(a.) Includes bonus rental on McAllen Medical Center, a UHS acute care hospital facility of $727 and $2,048 for the three and nine-month periods ended September 30, 2022, respectively, and includes bonus rental on three UHS acute care hospital facilities of $1,828 and $5,171 for the three and nine-month periods ended September 30, 2021, respectively. Please see disclosure above surrounding the December 31, 2021 asset purchase and sale transaction with UHS.

As previously disclosed, the lease on the specialty hospital located in Chicago, Illinois, expired on December 31, 2021 and the facility is currently vacant. During the three and nine-month periods ended September 30, 2021, we earned $390,000 and $1.2 million, respectively, of lease revenue in connection with this property. The operating expenses incurred by us in connection with this facility during the three and nine-month periods ended September 30, 2022 were $240,000 and $1.1 million, respectively. Prior to 2022, the former tenant was responsible for the operating expenses on this facility. Pursuant to the terms of the lease that expired in December, 2021, we earned approximately $1.6 million of lease revenue during the 2021 full year.

The leases on two specialty hospital facilities, located in Evansville, Indiana, and Corpus Christi, Texas, expired on May 31, 2019 and June 1, 2019, respectively. The hospital located in Evansville, Indiana, has remained vacant since September 30, 2019 and the hospital located in Corpus Christi, Texas, has remained vacant since June 1, 2019.

We estimate that the aggregate operating expenses for the three vacant specialty facilities, including the facility located in Chicago, Illinois, as well as the facilities located in Evansville, Indiana, and Corpus Christi, Texas, will approximate $900,000 during the remaining three months of 2022. Future operating expenses related to these facilities will be incurred by us during the time they remain owned and vacant. We continue to market these specialty facilities to potential interested parties. However, should these properties continue to remain vacant for an extended period of time, or should we incur substantial renovation or demolition costs to make the properties suitable for other operators/tenants/buyers, our future results of operations could be materially unfavorably impacted.

We are the lessee with various third parties, including subsidiaries of UHS, in connection with ground leases for land at fourteen of our consolidated properties. Our right-of-use land assets represent our right to use the land for the lease term and our lease liabilities represent our obligation to make lease payments arising from the leases. Right-of-use assets and lease liabilities were recognized upon adoption of Topic 842 based on the present value of lease payments over the lease term. We utilized our estimated incremental borrowing rate, which was derived from information available as of January 1, 2019, in determining the present value of lease payments. A right-of-use asset and lease liability are not recognized for leases with an initial term of 12 months or less, as these short-term leases are accounted for similarly to previous guidance for operating leases. We do not currently have any ground leases with an initial term of 12 months or less. As of September 30, 2022, our condensed consolidated balance sheet includes right-of-use land assets of approximately $11.5 million and ground lease liabilities of approximately $11.5 million. There were no newly leased assets for which a right-of-use asset was recorded in exchange for a new lease liability during the three and nine months ended September 30, 2022.
