On January 19, 2021, we completed the first of two phases in the Priory transaction in which we funded an £800 million interim mortgage loan on an identified portfolio of Priory real estate assets in the United Kingdom. On June 25, 2021, we completed the second phase of the transaction in which we converted this mortgage loan to fee simple ownership in a portfolio of 35 select real estate assets from Priory (now owned by Waterland Private Equity Fund VII C.V. (“Waterland VII”)) in individual sale-and-leaseback

transactions. The applicable purchase price for the asset was paid by us by proportionally converting and reducing the principal balance of the interim mortgage loan we made to Waterland VII in phase one. Therefore, the net aggregate purchase price for the real estate assets we acquired from Priory was approximately £800 million, plus customary stamp duty, tax, and other transaction costs. As part of the real estate acquisition (for which some of the assets were acquired by the share purchase of real estate holding entities), we incurred deferred income tax liabilities of approximately £47.1 million.

In addition to the real estate investment, on January 19, 2021, we made a 364-day, £250 million acquisition loan to Waterland VII, in connection with the closing of Waterland VII’s acquisition of Priory.

Finally, we also acquired a 9.9% passive equity interest in the Waterland VII affiliate that indirectly owns Priory for a nominal amount.

We funded this total investment using £500 million from a new $900 million interim credit facility as described in Note 4, £350 million from our revolving facility, and the remainder from cash on-hand.

On April 16, 2021, we made a CHF 145 million investment in Swiss Medical Network, our tenant via our Infracore SA (“Infracore”) equity investment.

On January 8, 2021, we made a $335 million loan to affiliates of Steward Health Care System LLC (“Steward”), which was used to redeem a similarly sized convertible loan from Steward’s former private equity sponsor.

On January 8, 2020, we acquired a portfolio of 30 acute care hospitals located throughout the United Kingdom for approximately £1.5 billion from affiliates of BMI Healthcare, Inc. (“BMI”). In a related transaction, affiliates of Circle Health Ltd. (“Circle”) entered into definitive agreements to acquire BMI and assume its operations in the United Kingdom subject to customary regulatory conditions. As part of our acquisition, we inherited 30 existing leases with the operator that had initial fixed terms ending in 2050, with no renewal options but with annual inflation-based escalators. Once final regulatory approval was received in the 2020 second quarter, these 30 leases with Circle were amended (effective June 16, 2020) to include two five-year renewal options and improve the annual inflation-based escalators. These 30 leases are cross-defaulted and guaranteed by Circle.

On June 24, 2020, we originated a CHF 45 million secured loan to Infracore, which was paid in full on December 2, 2020.

On May 13, 2020, we formed a joint venture for the purpose of investing in the operations of international hospitals. As part of the formation, we originated a $205 million acquisition loan. We have a 49% interest in this joint venture and are accounting for our investment using the fair value option election. The joint venture simultaneously purchased from Steward the rights and existing assets related to all present and future international opportunities previously owned by Steward for strategic, regulatory, and risk management purposes.

See table below for a status summary of our current development projects (in thousands):

Property	Commitment		Costs Incurred as of June 30, 2021		Estimated Rent Commencement Date

During the 2020 second quarter, we completed construction on one general acute care facility and one inpatient rehabilitation facility, both located in Birmingham, England. We began recognizing revenue on these two properties on June 29, 2020. These facilities are being leased to Circle pursuant to a long-term lease.

During the 2020 first quarter, we completed construction and began recording rental income on a general acute care facility located in Idaho Falls, Idaho. This facility commenced rent on January 21, 2020 and is being leased to Surgery Partners, Inc. pursuant to an existing long-term lease.

During the first half of 2021, we completed the sale of five facilities and an ancillary property for approximately $25 million, resulting in a net loss on real estate of approximately $0.4 million.

During the first half of 2020, we completed the disposition of five facilities and four ancillary properties for approximately $79 million. The transactions resulted in a net loss on real estate of $1.8 million.

We acquire and develop healthcare facilities and lease the facilities to healthcare operating companies under long-term net leases (typical initial fixed terms of at least 15 years) and most include renewal options at the election of our tenants, generally in five year increments. Approximately 99% of our leases provide annual rent escalations based on increases in the Consumer Price Index (or similar index outside the U.S.) and/or fixed minimum annual rent escalations (typically at least 2.0%). Many of our domestic leases contain purchase options with pricing set at various terms but in no case less than our total investment. For five properties with a carrying value of $230 million, our leases require a residual value guarantee from the tenant. Our leases typically require the tenant to handle and bear most of the costs associated with our properties including repair/maintenance, property taxes, and insurance. We routinely inspect our properties to ensure the residual value of each of our assets is being maintained. Except for leases classified as financing leases as noted below, all of our leases are classified as operating leases.

At June 30, 2021, leases on 13 Ernest Health, Inc. (“Ernest”) facilities and five Prime Healthcare Services, Inc. (“Prime”) facilities are accounted for as direct financing leases and leases on 13 of our Prospect Medical Holdings, Inc. (“Prospect”) facilities and five of our Ernest facilities are accounted for as a financing. The components of our total investment in financing leases consisted of the following (in thousands):

	As of June 30, 2021			As of December 31, 2020
Minimum lease payments receivable	$	1,206,411		$	1,228,966
Estimated residual values		203,818			203,818
Less: Unearned income and allowance for credit loss		(943,865	)		(969,061	)
Net investment in direct financing leases		466,364			463,723
Other financing leases (net of allowance for credit loss)		1,565,817			1,547,199
Total investment in financing leases	$	2,032,181		$	2,010,922

In the first six months of 2021, we collected $1.6 million of rent previously deferred due to the COVID-19 pandemic. Pursuant to our agreements with certain tenants, we expect the remaining outstanding deferred rent balance of approximately $9.8 million as of June 30, 2021, to be paid over specified periods in the future, with interest.

As discussed in previous filings, our original real estate portfolio of approximately 60 properties leased to Adeptus Health, Inc. (“Adeptus”) has gone through significant changes starting with Adeptus filing for Chapter 11 bankruptcy in 2017. During 2020, we transitioned the remaining facilities away from Adeptus, which resulted in impairment charges including approximately $9.9 million in the first half of 2020, along with a charge to writeoff straight-line rent and other receivables, partially offset by a draw on a $9.1 million letter of credit. However, these transition measures have also provided for new tenant relationships being formed with strong credit worthy operators like Ochsner Health System, Dignity Health, UC Health, and HCA Healthcare, that are now leasing approximately 40 of these transitional facilities under long-term leases. At June 30, 2021, 13 of these transitional properties, representing less than 1% of our total assets, remain vacant, and each of these properties are in various stages of being re-leased or sold. At June 30, 2021, we believe our investment in these real estate assets are fully recoverable, but no assurances can be given that we will not have any further impairments in future periods.

As noted in previous filings, we originally leased four acute care facilities to and had a mortgage loan on a fifth property (Olympia Medical Center) with Alecto Healthcare Services LLC (“Alecto”). During the first quarter of 2020, we donated the Wheeling facility to a local municipality, resulting in a $9.1 million real estate impairment charge. In addition, we re-leased one acute care facility to West Virginia University and sold another facility in 2020. In the first quarter of 2021, Alecto completed the sale of Olympia Medical Center to the UCLA Health System. Our proceeds of approximately $51 million from this sale were used to pay off the mortgage and working capital loans in full, with the remaining proceeds used to recover certain previously reserved past due amounts. At June 30, 2021, we continue to lease one acute care facility to Alecto representing less than 0.1% of our total assets.

The following is a summary of our loans (net of allowance for credit loss) (in thousands):

	As of June 30, 2021		As of December 31, 2020
Mortgage loans	$	219,561	$	248,080
Acquisition loans		688,106		338,273
Other loans		823,740		520,095
Total	$	1,731,407	$	1,106,448

The increase in acquisition loans relates to the £250 million loan funded in connection with the Priory Group Transaction (as more fully described above in Note 3).

Other loans consist of loans to our tenants for working capital and other purposes and include our shareholder loan made to the joint venture with Primotop Holdings S.à.r.l. (“Primotop”) in the amount of €297 million. The increase in other loans is primarily related to the $335 million loan to affiliates of Steward (as more fully described above in this Note 3), partially offset by the repayment of $75 million in other loans from Prime.

Pursuant to our existing 9.9% equity interest in Steward, we received an $11 million cash distribution during the first quarter of 2021, which was accounted for as a return of capital.

Pursuant to our 4.9% stake in Aevis Victoria SA (“Aevis”), we recorded a $1.9 million favorable non-cash fair value adjustment to mark our investment in Aevis stock to market during the first six months of 2021; whereas, this was a $6.8 million unfavorable non-cash fair value adjustment for the same period of 2020.

We monitor concentration risk in several ways due to the nature of our real estate assets that are vital to the communities in which they are located and given our history of being able to replace inefficient operators of our facilities, if needed, with more effective operators:
