​ Loans receivable held for sale—In December 2022, the Company began marketing a non-performing loan for sale and classified the loan in “Loans receivable held for sale” on the Company’s consolidated balance sheet. Prior to its transfer to loans receivable held for sale, the Company recorded a provision for loan losses of $23.8 million on the loan based on the Company’s intent to sell the loan based on a bid received from a third-party. The loan is recorded on the Company’s consolidated balance sheet at the estimated sales price of $37.7 million. In March 2021, the Company acquired land and simultaneously structured and entered into with the seller a Ground Lease on which a multi-family project will be constructed. The Company funded $16.1 million at closing and the Ground Lease documents provided for future funding obligations to the Ground Lease tenant of approximately $11.9 million of deferred purchase price and $52.0 million of leasehold improvement allowance upon achievement of certain milestones. At closing, the Company entered into an agreement with SAFE pursuant to which, subject to certain conditions being met, SAFE would acquire the ground lessor entity from the Company. The Company determined that the transaction did not qualify as a sale leaseback transaction and recorded the Ground Lease in “Loans receivable held for sale” on the Company’s consolidated balance sheet. Subsequent to closing, the Company funded approximately $6.0 million of the deferred purchase price to the Ground Lease tenant. The Company sold the ground lessor entity (and SAFE assumed all future funding obligations to the Ground Lease tenant) to SAFE in September 2021 for $22.1 million and recorded no gain or loss on the sale. In June 2021, the Company acquired a parcel of land for $42.0 million and simultaneously entered into a Ground Lease (refer to Note 5). The Company also concurrently entered into an agreement pursuant to which SAFE would acquire the Ground Lease from the Company. The Ground Lease was entered into with the seller of the land and did not qualify for sale leaseback accounting, and as such, was accounted for as a financing transaction and $42.0 million was recorded in “Loans receivable held for sale” on the Company’s consolidated balance sheet at the time of acquisition. In January 2022, the Company sold its loan receivable held for sale to the Ground Lease Plus Fund (refer to Note 8).
