Assisted living communities, independent living communities, memory care communities and combinations thereof are included in the assisted living property classification (collectively “ALF”).

Any reference to the number of properties or facilities, number of units, number of beds, number of operators and yield on investments in real estate are unaudited and outside the scope of our independent registered public accounting firm’s review of our consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board.

Owned Properties. Our Owned properties are leased pursuant to non-cancelable operating leases generally with an initial term of 10 to 15 years. Each lease is a triple net lease which requires the lessee to pay all taxes, insurance, maintenance and repairs, capital and non-capital expenditures and other costs necessary in the operations of the facilities. Many of the leases contain renewal options. The leases provide for fixed minimum base rent during the initial and renewal periods. The majority of our leases contain provisions for specified annual increases over the rents of the prior year that are generally computed in one of four ways depending on specific provisions of each lease:

Our leases that contain fixed annual rental escalations and/or have annual rental escalations that are contingent upon changes in the Consumer Price Index, are generally recognized on a straight-line basis over the minimum lease period. Certain leases have annual rental escalations that are contingent upon changes in the gross operating revenues of the property. This revenue is not recognized until the appropriate contingencies have been resolved.

The following table summarizes our investments in owned properties at March 31, 2021 (dollar amounts in thousands):

(2)	Includes three parcels of land held-for-use, and one behavioral health care hospital.

Future minimum base rents receivable under the remaining non-cancelable terms of operating leases excluding the effects of straight-line rent receivable, amortization of lease incentives and renewal options are as follows (in thousands):

(1)	Represents contractual cash rent, except for certain master leases which are based on estimated cash payments.

We monitor the collectability of our receivable balances, including deferred rent receivable balances, on an ongoing basis. We write-off uncollectible operator receivable balances, including straight line rent receivable balances, as a reduction to rental income in the period such balances are no longer probable of being collected. Therefore, recognition of rental income is limited to the lesser of the amount of cash collected or rental income reflected on a “straight-line” basis for those customer receivable balances deemed uncollectible. As of March 31, 2021, we have 16 operators that are being accounted for on a “cash-basis”. We wrote-off straight-line rent receivable of $758,000 and $0 for the three months ended March 31, 2021 and 2020, respectively.

We continue to take into account the current financial condition of our operators, including consideration of the impact of COVID-19, in our estimation of our uncollectible accounts and deferred rents receivable at March 31, 2021. We are closely monitoring the collectability of such rents and will adjust future estimations as appropriate as further information becomes known.

The following table summarizes components of our rental income for the three months ended March 31, 2021 and 2020 (in thousands):

Total	$	31,973		$	38,035

(1)	Decreased primarily due to reduction of rent from Senior Lifestyle and abated and deferred rent partially offset by increased rent from acquisitions and completion of development projects and contractual rent increases.

(2)

The variable rental income for the three months ended March 31, 2021, includes reimbursement of real estate taxes by our lessees of $3,538. The variable rental income for the three months ended March 31, 2020 includes contingent rental income of $60 and $4,222 related to reimbursement of real estate taxes by our lessees.

(3)	Decreased due to more leases accounted for on a cash basis and normal amortization partially offset by increases due to a 50% reduction in 2021 rent escalations for those leases accounted for on a straight-line basis.

(4)	Represents a straight-line rent receivable write-off.

Some of our lease agreements provide purchase options allowing the lessees to purchase the properties they currently lease from us. The following table summarizes information about purchase options included in our lease agreements (dollar amount in thousands):

On March 11, 2020, the World Health Organization declared the outbreak of COVID-19 as a pandemic, and on March 13, 2020, the United States declared a national emergency with regard to COVID-19. At March 31, 2021, in conjunction with the continued levels of uncertainty related to the adverse effects of COVID-19, we assessed the probability of collecting substantially all of our lease payments through maturity and concluded that we did not have sufficient information available to evaluate the impact of COVID-19 on the collectibility of our lease payments. The extent to which COVID-19 could impact our operators and the collectibility of our future lease payments will depend on the future developments including the financial impact significance, government support and subsidies and the duration of the pandemic.

In recognition of the pandemic impact affecting our operators, we have agreed to rent abatements totaling $600,000 and rent deferrals for certain operators totaling $1,144,000 during the first quarter of 2021. The $1,743,000 in rent abatements and deferrals during the three months ended March 31, 2021,

represented approximately 4% of our first quarter of 2021 contractual rent. Additionally, we reduced 2021 rent and interest escalations by 50% to support eligible operators during the continuing COVID-19 crisis. The rent and interest escalation reductions were given in the form of a rent and interest credit in recognition of operators’ increased costs due to COVID-19. We have elected to recognize the rent credits given to the eligible operators where we accrue rent on a straight-line basis over the remaining life of those respective leases. During the first quarter of 2021, we recognized a decrease of $292,000 of GAAP revenue and $1,200,000 in funds available for distribution.

(

(1)	Calculation of net (loss) gain includes cost of sales.

(2)	We recognized additional gain due to the reassessment adjustment of the holdbacks related to properties sold during 2019 and 2020, under the expected value model per ASC Topic 606, Contracts with Customers (“ASC 606”).

(3)

One of the transactions includes a holdback of $838 which is held in an interest-bearing account with an escrow holder on behalf of the buyer for potential specific losses. During 2020, we received $150 of the holdback. The remaining holdback expires in March 2022. Using the expected value model per ASC 606, we estimated and recorded the holdback value of $471 at closing.

(1)	The majority of the mortgage loans provide for annual increases in the interest rate after a certain time period increasing by 2.25%.

(2)	Some loans contain certain guarantees, provide for certain facility fees and the majority of the mortgage loans have a 30-year term.

(3)	The properties securing these mortgage loans are located in one state and are operated by one operator.

We apply ASU No. 2016-13, Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”) and the “expected loss” model to estimate our loan losses on our mortgage loans and notes receivable. In determining the expected losses on these receivables, we utilize the probability of default and discounted cash flow methods. Further, we stress-test the results to reflect the impact of unknown adverse future events including recessions.

As of March 31, 2021, the accrued interest receivable of $34,491,000 was not included in the measurement of expected credit losses on the mortgage loan receivable and notes receivable (see Note 4). We elected not to measure an allowance for expected credit losses on the related accrued interest receivable using the expected credit loss standard. Rather, we have elected to write-off accrued interest receivable by reversing interest income and/or recognizing credit loss expense as incurred. We review the collectability of the accrued interest receivable quarterly as part of our review of the mortgage loan or notes receivables including the performance of the underlying collateral. For the three months ended March 31, 2021 and 2020, the Company did not write-off any accrued interest receivable.
