Other officers of RMR, including Ms. Clark and certain of our officers, serve as managing trustees, or officers of certain of these companies. In addition, officers of RMR and RMR Inc. serve as our officers and officers of other companies to which RMR or its subsidiaries provide management services. As of December 31, 2024, ABP Trust and Adam D. Portnoy owned 9.8% of our outstanding common shares. AlerisLife. Until March 20, 2023, we were AlerisLife's largest stockholder, owning approximately 31.9% of AlerisLife's outstanding common shares, and ABP Acquisition LLC, or ABP Acquisition, a subsidiary of ABP Trust, together with ABP Trust, owned approximately 6.1% of AlerisLife's outstanding common shares. Five Star is an operating division of AlerisLife. Five Star manages certain of the senior living communities we own pursuant to the Master Management Agreement. RMR provides management services to both us and AlerisLife. AlerisLife participates in our property insurance program for the senior living communities AlerisLife owns. The premiums AlerisLife pays for this coverage are allocated pursuant to a formula based on the profiles of the properties included in the program. See Note 6 for further information regarding our relationships, agreements and transactions with AlerisLife (including Five Star) and Note 2 for further information regarding our investment in AlerisLife. On February 2, 2023, AlerisLife entered into an Agreement and Plan of Merger, or the ALR Merger Agreement, with certain subsidiaries of ABP Trust, pursuant to which ABP Trust acquired all of the publicly held outstanding AlerisLife common shares at a price of $1.31 per share, or the Tender Offer Price, by tender offer. In connection with the ALR Merger Agreement, on February 2, 2023, we agreed to tender all the AlerisLife common shares that we and our subsidiary then owned into the tender offer at the Tender Offer Price, subject to the right, but not the obligation, to purchase, on or before December 31, 2023, AlerisLife common shares at the Tender Offer Price, and otherwise pursuant to a stockholders agreement to be entered into at the time of any such purchase. On December 20, 2023, we and ABP Trust extended our right to purchase AlerisLife common shares until March 31, 2024. On February 16, 2024, we exercised this purchase right and acquired, together with our applicable TRS, approximately 34.0% of the then outstanding AlerisLife common shares from ABP Trust at the Tender Offer Price, for a total purchase price of $15,459, including transaction related costs, and we, our applicable TRS, ABP Trust and AlerisLife entered into a stockholders agreement. Following this acquisition, ABP Trust owns the remaining approximate 66.0% of AlerisLife. In connection with AlerisLife's sale of its Ageility branded business to a subsidiary of Fox Rehabilitation on June 17, 2024, we approved Five Star's sublease to a subsidiary of Fox Rehabilitation of space at certain of our senior living communities, which is used to provide certain outpatient rehabilitation and wellness services. On February 14, 2025, AlerisLife paid an aggregate cash dividend of $50,000 to its stockholders. Our pro rata share of this cash dividend was $17,000. See Note 6 for further information regarding our relationships, agreements and transactions with AlerisLife (including Five Star) and Note 2 for further information regarding our investment in AlerisLife. Our Manager, RMR. We have two agreements with RMR to provide management services to us: (1) a business management agreement, which relates to our business generally; and (2) a property management agreement, which relates to the property level operations of many of our properties, including our medical office and life science properties, and major renovation or repositioning activities at our senior living communities that we may request RMR to manage from time to time. See Note 7 for further information regarding our management agreements with RMR. Our Joint Ventures. In connection with our entering into the LSMD JV in January 2022, we paid mortgage escrow amounts and closing costs that were payable by that joint venture. The remaining costs totaled $4,056 as of December 31, 2024 and are included in other assets, net, in our consolidated balance sheet. RMR provides management services to each of the Seaport JV and the LSMD JV. See Note 7 for further information regarding those management agreements with RMR. Leases with RMR. We lease office space to RMR in certain of our properties for RMR's property management offices. We recognized rental income from RMR for leased office space of $460, $196 and $303 for the years ended December 31, 2024, 2023 and 2022, respectively. Our office space leases with RMR are terminable by RMR if our management agreements with RMR are terminated. Share Awards to RMR Employees. As described in Note 5, we award shares to our officers and other employees of RMR annually. Generally, one fifth of these awards vest on the award date and one fifth vests on each of the next four anniversaries of the award dates. In certain instances, we may accelerate the vesting of an award, such as in connection with the award holder's retirement as an officer of us or an officer or employee of RMR. These awards to RMR employees are in addition to the share awards to our Managing Trustees, as Trustee compensation, and the fees we paid to RMR. See Note 5 for information regarding our share awards and activity as well as certain share purchases we made in connection with share award recipients satisfying tax withholding obligation on vesting share awards.
