Leases | 8. Leases ​ Leases as a Lessee: ​ The Company entered into a noncancelable contract with a third party to obtain office space that commenced on September 1, 2010. The contract was amended on October 25, 2016 to extend the contract through September 30, 2024. As of December 31, 2022, the Company’s right-of-use asset was $0.7 million, which is included in prepaid and other assets on the consolidated balance sheet as of December 31, 2022. ​ The Company has an option to extend the terms of its office space lease with one 5-year extension option. As of December 31, 2022, the exercise of the extension option was not reasonably certain. Therefore, the extension option is not recognized as part of the Company’s right-of-use asset and lease liability. ​ A discount rate equal to the Company’s incremental borrowing rate was applied to the future monthly contractual lease payments remaining as of December 31, 2022 to compute the lease liability. The incremental borrowing rate is the rate equal to the closest borrowing under the BofA Revolver at the time of the Company’s adoption of ASU 2016-02. ​

​ Leases as a Lessor: ​ The Company is a lessor of commercial real estate with operations that include the leasing of office and industrial properties. Many of the leases with customers contain options to extend leases at a fair market rate and may also include options to terminate leases. The Company considers several inputs when evaluating the amount it expects to derive from its leased assets at the end of the lease terms, such as the remaining useful life, expected market conditions, fair value of lease payments, expected fair values of underlying assets, and expected deployment of the underlying assets. The Company’s strategy to address its risk for the residual value in its commercial real estate is to re-lease the commercial space. ​ The Company has elected to apply the practical expedient to not separate non-lease components from the related lease component of real estate leases. This combined component is primarily comprised of fixed lease payments, early termination fees, common area maintenance cost reimbursements, and parking lease payments. The Company applies ASC 842-Leases to the combined lease and non-lease components. ​ For the year ended December 31, 2022, 2021 and 2020, the Company recognized the following amounts of income relating to lease payments: ​
