•our previously existing master leases with Five Star for all of our senior living communities that Five Star leased, as well as our previously existing management agreements and pooling agreements with Five Star for our senior living communities that Five Star managed, were terminated and replaced with new management agreements and a related omnibus agreement, which agreements were subsequently replaced in June 2021, as described below;

•as consideration for these share issuances, we provided Five Star with $75,000 of additional consideration by assuming certain of Five Star's working capital liabilities and making cash payments to Five Star, resulting in a gain on lease termination of $22,896 for the year ended December 31, 2020 in our consolidated statements of comprehensive income (loss); and

•pursuant to a guaranty agreement dated as of January 1, 2020 and amended and restated on June 9, 2021, made by AlerisLife in favor of our applicable subsidiaries, AlerisLife has guaranteed the payment and performance of each of its applicable subsidiary's obligations under our applicable management agreements with Five Star.

•that Five Star agreed to cooperate with us in transitioning 108 of our senior living communities with approximately 7,500 living units to other third party managers without our payment of any termination fee to Five Star;

•that we no longer have the right to sell up to an additional $682,000 of senior living communities currently managed by Five Star and terminate Five Star's management of those communities without our payment of a fee to Five Star upon sale;

•that Five Star is continuing to manage 119 of the 120 of our senior living communities that were included as part of the management arrangements (the management for one active adult community was terminated by mutual agreement effective October 31, 2022), and that the skilled nursing units in all of our continuing care retirement communities that Five Star is continuing to manage, which then included approximately 1,500 living units, were closed and are being evaluated and repositioned;

•that beginning in 2025, we will have the right to terminate up to 10% of the senior living communities that Five Star is continuing to manage, based on total revenues per year for failure to meet 80% of a target earnings before interest, taxes, depreciation and amortization, or EBITDA, for the applicable period;

•that the incentive fee that Five Star may earn in any calendar year for the senior living communities that Five Star is continuing to manage is no longer subject to a cap and that any senior living communities that are undergoing a major renovation or repositioning are excluded from the calculation of the incentive fee;

Pursuant to these changes, we and Five Star entered into an amended and restated master management agreement, or the Master Management Agreement, for the senior living communities that Five Star is continuing to manage. These agreements replaced our prior master leases and management and pooling agreements with Five Star. In addition, AlerisLife

delivered to us a related amended and restated guaranty agreement pursuant to which AlerisLife is continuing to guarantee the payment and performance of its subsidiaries' obligations under the applicable management agreements.

Pursuant to the Master Management Agreement, Five Star receives a management fee equal to 5% of the gross revenues realized at the applicable senior living communities plus reimbursement for its direct costs and expenses related to such communities. Commencing with the calendar year 2021, Five Star may receive an annual incentive fee equal to 15% of the amount by which the annual EBITDA of all communities on a combined basis exceeds the target EBITDA for all communities on a combined basis for such calendar year. The target EBITDA for those communities on a combined basis is increased annually based on the greater of the annual increase of the consumer price index, or CPI, or 2%, plus 6% of any capital investments funded at the managed communities on a combined basis in excess of the target capital investment. Unless otherwise agreed, the target capital investment increases annually based on the greater of the annual increase of CPI or 2%. Any senior living communities that are undergoing a major renovation or repositioning are excluded from the calculation of the incentive fee.

The Master Management Agreement expires in 2036, subject to Five Star's right to extend for two consecutive five year terms if Five Star achieves certain performance targets for the combined managed communities portfolio, unless earlier terminated. Pursuant to the Master Management Agreement, beginning in 2025, we have the right to terminate up to 10% of the senior living communities that Five Star is continuing to manage, based on total revenues per year for failure to meet 80% of a target EBITDA for the applicable period.

In 2021, we completed the transition of 107 of the 108 senior living communities, containing 7,340 living units, from Five Star to other third party managers. The remaining senior living community was closed in February 2022 and we are assessing opportunities to redevelop that property. We continue to lease our senior living communities that have been transitioned to other managers to our TRSs. We incurred costs related to retention and other transition costs for these communities. We recorded $2,096 and $17,363 for the years ended December 31, 2022 and 2021, respectively, of these costs to acquisition and certain other transaction related costs in our consolidated statements of comprehensive income (loss).

Our Senior Living Communities Managed by Five Star. Five Star managed 119, 120 and 235 of our senior living communities as of December 31, 2022, 2021 and 2020, respectively. We lease our senior living communities that are managed by Five Star to our TRSs, and Five Star manages these communities pursuant to long term management agreements. Effective October 31, 2022, Five Star ceased managing an active adult community we own located in Plano, TX, and RMR assumed management of that community pursuant to our property management agreement with RMR. We paid Five Star a termination fee of $350 in connection with the termination of Five Star's management of this community. As described above, pursuant to the Transaction Agreement, effective January 1, 2020, we replaced our long term management and pooling agreements with Five Star with new management agreements and a related omnibus agreement, which agreements were subsequently replaced in June 2021 with the Master Management Agreement, the terms of which are described above.

We incurred management fees payable to Five Star of $37,037, $47,479 and $62,880 for the years ended December 31, 2022, 2021 and 2020, respectively. For the years ended December 31, 2022, 2021 and 2020, $33,737, $43,864 and $60,413, respectively, of the total management fees were expensed to property operating expenses in our consolidated statements of comprehensive income (loss) and $3,300, $3,615 and $2,467, respectively, were capitalized in our consolidated balance sheets. The amounts capitalized are being depreciated over the estimated useful lives of the related capital assets.

In addition to providing management services to us, Five Star also provides certain other services to residents at some of the senior living communities it manages for us, such as rehabilitation services. At senior living communities Five Star manages for us where Five Star provides rehabilitation services on an outpatient basis, the residents, third party payers or government programs pay Five Star for those rehabilitation services. At senior living communities Five Star manages for us where Five Star provides both inpatient and outpatient rehabilitation services, we generally pay Five Star for those rehabilitation services and charges for these services are included in amounts charged to residents, third party payers or government programs. We incurred fees of $6,289, $11,233 and $25,687 for the years ended December 31, 2022, 2021 and 2020, respectively, with respect to rehabilitation services Five Star provided at our senior living communities that are payable by us. These amounts are included in property operating expenses in our consolidated statements of comprehensive income (loss).

As a result of routine monitoring protocols that are a part of Five Star's compliance program activities related to Medicare billing, Five Star discovered potentially inadequate documentation at one of our senior living communities that Five Star manages. This monitoring was not initiated in response to any specific complaint or allegation but rather was of the type that Five Star periodically undertakes to test its compliance with applicable Medicare billing rules. We and Five Star voluntarily disclosed this matter to the United States Department of Health and Human Services, Office of the Inspector General, or the

OIG, pursuant to the OIG's Provider Self-Disclosure Protocol. In January 2021, we and Five Star settled this matter with the OIG and we agreed to pay approximately $5,763 in exchange for a customary release, but we and Five Star did not admit any liability. We paid that amount to the OIG in January 2021. Five Star refunded to us $115 of management fees it previously received relating to the Medicare payments we refunded to the OIG. With respect to this settlement amount, we accrued a revenue reserve of $3,842 at December 31, 2020 for historical Medicare payments we received and agreed to repay to the OIG and we recorded expenses of $1,921 for the year ended December 31, 2020 for OIG-imposed penalties.

Since January 1, 2020, we sold certain senior living communities that were then managed by Five Star. We and Five Star terminated our management agreements for these senior living communities in connection with these sales. See Note 3 for further information regarding these sales.

Our Senior Living Communities Managed by Other Third Party Managers. As of December 31, 2022 and 2021, respectively, our other third party managers managed 111 and 107 of our senior living communities. The terms of the management agreements with the other third party managers are generally as follows: the other third party managers will receive a management fee equal to 5% to 6% of the gross revenues realized at the applicable senior living communities plus reimbursement for direct costs and expenses related to such communities. These agreements generally also provide for the other third party managers to earn a minimum base fee for a portion of the term of the agreement. Additionally, the other third party managers have the ability to earn incentive fees equal to 15% to 25% of the amount by which EBITDA of the applicable communities exceeds the target EBITDA for the applicable communities. The other third party managers can also earn a construction supervision fee ranging between 3% and 5% of construction costs.

The initial terms of the management agreements with the other third party managers are generally five years, subject to automatic extensions of successive terms of two years each unless earlier terminated or timely notice of nonrenewal is delivered. The management agreements with the other third party managers also generally provide us with the right to terminate the management agreements for communities that do not earn 70% to 80% of the target EBITDA for such communities, after an agreed upon stabilized period.

We incurred management fees payable to our other third party managers of $20,739 and $6,239 for the years ended December 31, 2022 and 2021, respectively. These amounts are included in property operating expenses in our consolidated financial statements.
