Pay vs Performance Disclosure |  |  |
Pay vs Performance Disclosure, Table | Pay Versus Performance ​ The following table and footnotes summarize the total compensation we paid to our named executive officers (our “NEOs”), compensation “actually paid” to our NEOs (calculated in accordance with SEC rules), the cumulative total shareholder return of the Company and our net income for the past three fiscal years. None of our NEOs is employed by us. Tremont, a subsidiary of RMR, provides, or arranges with RMR to provide, services that otherwise would be provided by employees and either RMR or Tremont employs and compensates our NEOs directly and in their sole discretion in connection with their services rendered to Tremont, RMR, to us and other companies to which RMR or Tremont provide management services. For information regarding the compensation paid by us to Tremont and RMR, please see the below “Certain Related Person Transactions” section. We do not pay our NEOs salaries or bonuses or provide other cash compensation or employee benefits. We provide equity incentive compensation to our NEOs pursuant to the terms of our 2021 Equity Plan.

​ * The cumulative total shareholder return (“TSR”) for 2021 is based on the period from January 5, 2021 through December 31, 2021, and the three year cumulative TSR for 2023 is based on the period from January 5, 2021 through December 31, 2023. On January 5, 2021, we ceased to be a registered investment company under the Investment Company Act of 1940 (the “1940 Act”), as amended. Since that deregistration, we fully implemented the change in our business mandate that our shareholders had approved in April 2020 to focus primarily on originating and investing in first mortgage whole loans secured by middle market and transitional CRE. Accordingly, we have not included the time period prior to that deregistration in the calculation of TSR. ​ (1) The following table summarizes the applicable deductions and additions for the PEO in the calculation of Compensation Actually Paid to the PEO. ​ PEO Compensation Actually Paid
