ORGANIZATION [Abstract]
ORGANIZATION	NOTE 1 - ORGANIZATION Omega Healthcare Investors, Inc. (“Parent”), is a Maryland corporation that, together with its consolidated subsidiaries (collectively, “Omega”, the “Company”, “we”, “our”, “us”) invests in healthcare-related real estate properties located in the United States (“U.S.”) and the United Kingdom (“U.K.”). Our core business is to provide financing and capital to the long-term healthcare industry with a particular focus on skilled nursing facilities (“SNFs”), assisted living facilities (“ALFs”), and to a lesser extent, independent living facilities (“ILFs”), rehabilitation and acute care facilities (“specialty facilities”) and medical office buildings (“MOBs”). Our core portfolio consists of our long-term “triple-net” leases and real estate loans with healthcare operating companies and affiliates (collectively, our “operators”). In addition to our core investments, we make loans to operators and/or their principals. From time to time, we also acquire equity interests in joint ventures or entities that support the long-term healthcare industry and our operators. Omega has elected to be taxed as a real estate investment trust (“REIT”) for federal income tax purposes and is structured as an umbrella partnership REIT (“UPREIT”) under which all of Omega's assets are owned directly or indirectly by, and all of Omega's operations are conducted directly or indirectly through, its operating partnership subsidiary, OHI Healthcare Properties Limited Partnership (collectively with subsidiaries, “Omega OP”). Omega has exclusive control over Omega OP’s day-to-day management pursuant to the partnership agreement governing Omega OP. As of December 31, 2022, Parent owned approximately 97% of the issued and outstanding units of partnership interest in Omega OP (“Omega OP Units”), and other investors owned approximately 3% of the outstanding Omega OP Units.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Accounting Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Consolidation Omega’s consolidated financial statements include the accounts of (i) Parent, (ii) all direct and indirect wholly-owned subsidiaries of Omega, including Omega OP, (iii) other entities in which Omega or Omega OP has a majority voting interest and control and (iv) variable interest entities (“VIEs”) of which Omega is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation, and Omega’s net earnings are reduced by the portion of net earnings attributable to noncontrolling interests. GAAP requires us to identify entities for which control is achieved through means other than voting rights and to determine which business enterprise, if any, is the primary beneficiary of VIEs. A VIE is broadly defined as an entity with one or more of the following characteristics: (a) the total equity investment at risk is insufficient to finance the entity’s activities without additional subordinated financial support; (b) as a group, the holders of the equity investment at risk lack (i) the ability to make decisions about the entity’s activities through voting or similar rights, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity; or (c) the equity investors have voting rights that are not proportional to their economic interests, and substantially all of the entity’s activities either involve, or are conducted on behalf of, an investor that has disproportionately few voting rights. We may change our original assessment of a VIE upon subsequent events such as the modification of contractual arrangements that affects the characteristics or adequacy of the entity’s equity investments at risk and the disposition of all or a portion of an interest held by the primary beneficiary. Our variable interests in VIEs may be in the form of equity ownership, leases, guarantees and/or loans with our operators. We analyze our agreements and investments to determine whether our operators or unconsolidated joint ventures are VIEs and, if so, whether we are the primary beneficiary. We consolidate a VIE when we determine that we are its primary beneficiary. We identify the primary beneficiary of a VIE as the enterprise that has both: (i) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance; and (ii) the obligation to absorb losses or the right to receive benefits of the VIE that could be significant to the entity. Factors considered in determining whether we are the primary beneficiary of an entity include: (i) our voting rights, if any; (ii) our involvement in day-to-day capital and operating decisions; (iii) our risk and reward sharing; (iv) the financial condition of the operator or joint venture and (iv) our representation on the VIE’s board of directors. We perform this analysis on an ongoing basis. As of December 31, 2022, we have one joint venture that is a consolidated VIE as we have concluded that we are the primary beneficiary through our equity investment in the entity. We also have consolidated VIEs related to the Exchange Accommodation Titleholders (“EATs”) discussed in Note 3 – Real Estate Asset Acquisitions and Development. As of December 31, 2021, we did not have any VIEs that we consolidated. Revenue Recognition Rental Income Rental income from operating leases is recognized on a straight-line basis, inclusive of fixed annual escalators and lease inducements, over the lease term when we have determined that the collectibility of substantially all of the lease payments is probable. Certain of our operating leases contain provisions for an increase based on the change in pre-determined formulas from year to year (e.g., increases in the Consumer Price Index). We do not include in our measurement of our lease receivables these variable increases until the specific events that trigger the variable payments have occurred. Our leased real estate properties are leased under provisions of single or master leases with initial terms typically ranging from 5 to 15 years. Some of our leases have options to extend, terminate or purchase the facilities, which are considered when determining the lease term. We assess the probability of collecting substantially all payments due under our leases on several factors, including, among other things, payment history, the financial strength of the lessee and any guarantors, as applicable, historical operations and operating trends, current and future economic conditions, and expectations of performance (which includes known substantial doubt about an operator’s ability to continue as a going concern). If our evaluation of these factors indicates it is probable that we will be unable to collect substantially all rents, we recognize a charge to rental income to write off straight-line rent receivables and limit our rental income to the lesser of lease income on a straight-line basis plus variable rents when they become accruable or cash collected. Provisions for uncollectible lease payments are recognized as a direct reduction to rental income. If we change our conclusion regarding the probability of collecting rent payments required by a lessee, we may recognize an adjustment to rental income in the period we make a change to our prior conclusion, potentially resulting in increased volatility of rental income. Under the terms of our leases, the lessee is responsible for all maintenance, repairs, taxes and insurance on the leased properties. Certain of our operating leases require the operators to reimburse us for property taxes and other expenditures that are not considered components of the lease and therefore no consideration is allocated to them as they do not result in the transfer of a good or service to the operators. We have determined that all of our leases qualify for the practical expedient, under Accounting Standards Codification (“ASC”) 842, Leases (“Topic 842”), to not separate the lease and non-lease components because (i) the lease components are operating leases and (ii) the timing and pattern of recognition of the non-lease components are the same as the lease components. Certain operators are obligated to pay directly their obligations under their leases for real estate taxes, insurance and certain other expenses. These obligations, which have been assumed by the tenants under the terms of their respective leases, are not reflected in our consolidated financial statements. To the extent any tenant responsible for these obligations under their respective lease defaults on its lease or if it is deemed probable that the tenant will fail to pay for such costs, we would record a liability for such obligation. We have elected to exclude sales and other similar taxes from the measurement of lease revenue and expense. Loan Interest Income Interest income is recognized as earned over the term of the related real estate and non-real estate loans receivable. Interest income is recorded on an accrual basis to the extent that such amounts are expected to be collected using the effective interest method. In applying the effective interest method, the effective yield on a loan is determined based on its contractual payment terms, adjusted for prepayment terms. Direct Financing Lease Income As of December 31, 2022, we have one lease for a facility that is classified as a direct financing lease. For leases accounted for as direct financing leases, we record the present value of the future minimum lease payments (utilizing a constant interest rate over the term of the lease agreement) as a receivable and record interest income based on the contractual terms of the lease agreement. Costs related to originating direct financing leases are deferred and amortized on a straight-line basis as a reduction to income from direct financing leases over the term of the direct financing leases. Real Estate Sales We recognize gains on the disposition of real estate when the recognition criteria have been met, generally at the time the risks and rewards and title have transferred, and we no longer have substantial continuing involvement with the real estate sold. Gains on the sale of real estate are recognized pursuant to provisions under Accounting Standards Codification (“ASC”) 610-20, Gains and Losses from the Derecognition of Nonfinancial Assets. Under ASC 610-20, we determine whether the transaction is a sale to a customer or non-customer. As a REIT, we do not sell real estate within the ordinary course of our business and therefore, expect that our sale transactions will not be contracts with customers. ASC 610-20 refers to the revenue recognition principles under ASC 606, Revenue from Contracts with Customers. Under ASC 610-20, if we determine we do not have a controlling financial interest in the entity that holds the asset and the arrangement meets the criteria to be accounted for as a contract, we will dispose of the asset and recognize a gain or loss on the sale of the real estate when control of the underlying asset transfers to the buyer. If we determine a sale has not occurred under ASC 610-20, we continue to record the asset on the Consolidated Balance Sheets and related depreciation expense on the Consolidated Statements of Operations. Fair Value Measurement The Company measures and discloses the fair value of nonfinancial and financial assets and liabilities utilizing a hierarchy of valuation techniques based on whether the inputs to a fair value measurement are considered to be observable or unobservable in a marketplace. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. This hierarchy requires the use of observable market data when available. These inputs have created the following fair value hierarchy: ● Level 1 - quoted prices for identical instruments in active markets; ● Level 2 - quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and ● Level 3 - fair value measurements derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. The Company measures fair value using a set of standardized procedures that are outlined herein for all assets and liabilities which are required to be measured at fair value. When available, the Company utilizes quoted market prices from an independent third-party source to determine fair value and classifies such items in Level 1. In some instances where a market price is available, but the instrument is in an inactive or over-the-counter market, the Company consistently applies the dealer (market maker) pricing estimate and classifies such items in Level 2. If quoted market prices or inputs are not available, fair value measurements are based upon valuation models that utilize current market or independently sourced market inputs, such as interest rates, option volatilities, credit spreads and/or market capitalization rates. Items valued using such internally-generated valuation techniques are classified according to the lowest level input that is significant to the fair value measurement. As a result, these items could be classified in either Level 2 or Level 3 even though there may be some significant inputs that are readily observable. Internal fair value models and techniques used by the Company include discounted cash flow and Monte Carlo valuation models. Risks and Uncertainties including COVID-19 The Company is subject to certain risks and uncertainties affecting the healthcare industry, including those stemming from the novel coronavirus (“COVID-19”) global pandemic, which has disproportionately impacted the senior care sector, as well as those stemming from healthcare legislation and changing regulation by federal, state and local governments. Additionally, we are subject to risks and uncertainties as a result of changes affecting operators of nursing home facilities due to the actions of governmental agencies and insurers to limit the rising cost of healthcare services. Real Estate Acquisitions Upon acquisition of real estate properties, we evaluate the acquisition to determine if it is a business combination or an asset acquisition. Our real estate acquisitions are generally accounted for as asset acquisitions as substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If the acquisition is determined to be an asset acquisition, the Company records the purchase price and other related costs incurred to the acquired tangible assets and identified intangible assets and liabilities on a relative fair value basis. In addition, costs incurred for asset acquisitions including transaction costs, are capitalized. If the acquisition is determined to be a business combination, we record the purchase of properties to net tangible and identified intangible assets acquired and liabilities assumed at fair value. Goodwill is measured as the excess of the fair value of the consideration transferred over the fair value of the identifiable net assets. Transaction costs are expensed as incurred as part of a business combination. In making estimates of fair value for purposes of recording asset acquisitions and business combinations, we utilize a number of sources, including independent appraisals that may be obtained in connection with the acquisition or financing of the respective property and other market data. The Company determines the fair value of acquired assets and liabilities as follows: ● Land is determined based on third-party appraisals which typically include market comparables. ● Buildings and site improvements acquired are valued using a combination of discounted cash flow projections that assume certain future revenues and costs and consider capitalization and discount rates using current market conditions as well as the residual approach. ● Furniture and fixtures are determined based on third-party appraisals which typically utilize a replacement cost approach. ● Mortgages and other investments are valued using a discounted cash flow analysis, using interest rates being offered for similar loans to borrowers with similar credit ratings. ● Investments in joint ventures are valued based on the fair value of the joint ventures’ assets and liabilities. Differences, if any, between the Company’s basis and the joint venture’s basis are generally amortized over the lives of the related assets and liabilities, and such amortization is included in the Company’s share of earnings (losses) of the joint venture. ● Intangible assets and liabilities acquired are valued using a combination of discounted cash flow projections as well as other valuation techniques based on current market conditions for the intangible asset or liability being acquired. When evaluating below market leases we consider extension options controlled by the lessee in our evaluation. ● Other assets acquired and liabilities assumed are typically valued at stated amounts, which approximate fair value on the date of the acquisition. ● Assumed debt balances are valued by discounting the remaining contractual cash flows using a current market rate of interest. ● Noncontrolling interests are valued using a stock price on the acquisition date. Real Estate Properties Real estate properties are carried at initial recorded value less accumulated depreciation. The costs of significant improvements, renovations and replacements, including interest are capitalized. Our interest expense reflected in the Consolidated Statements of Operations has been reduced by the amounts capitalized. For the years ended December 31, 2022, 2021 and 2020, we capitalized $3.2 million, $1.5 million and $10.0 million, respectively, of interest to our projects under development. In addition, we capitalize leasehold improvements when certain criteria are met, including when we supervise construction and will own the improvement. Expenditures for maintenance and repairs are expensed as they are incurred. Depreciation is computed on a straight-line basis over the estimated useful lives ranging from 20 to 40 years for buildings, eight three Management evaluates our real estate properties for impairment indicators at each reporting period, including the evaluation of our assets’ useful lives. The judgment regarding the existence of impairment indicators is based on factors such as, but not limited to, market conditions, operator performance including the current payment status of contractual obligations and expectations of the ability to meet future contractual obligations, legal structure, as well as our intent with respect to holding or disposing of the asset. If indicators of impairment are present, management evaluates the carrying value of the related real estate investments in relation to management’s estimate of future undiscounted cash flows of the underlying facilities. The estimated future undiscounted cash flows are generally based on the related lease which relates to one or more properties and may include cash flows from the eventual disposition of the asset. In some instances, there may be various potential outcomes for a real estate investment and its potential future cash flows. In these instances, the undiscounted future cash flows used to assess the recoverability of the assets are probability-weighted based on management’s best estimates as of the date of evaluation. Impairment losses related to long-lived assets are recognized when expected future undiscounted cash flows based on our intended use of the property are determined to be less than the carrying values of the assets. An adjustment is made to the net carrying value of the real estate investments for the excess of carrying value over fair value. The fair value of the real estate investment is determined based on current market conditions and considers matters such as rental rates and occupancies for comparable properties, recent sales data for comparable properties, and, where applicable, contracts or the results of negotiations with purchasers or prospective purchasers. Additionally, our evaluation of fair value may consider valuing the property as a nursing home or other healthcare facility as well as alternative uses. All impairments are taken as a period cost at that time, and depreciation is adjusted going forward to reflect the new value assigned to the asset. Management’s impairment evaluation process, and when applicable, impairment calculations involve estimation of the future cash flows from management’s intended use of the property as well as the fair value of the property. Changes in the facts and circumstances that drive management’s assumptions may result in an impairment to our assets in a future period that could be material to our results of operations. Assets Held for Sale We consider properties to be assets held for sale when (1) management commits to a plan to sell the property; (2) it is unlikely that the disposal plan will be significantly modified or discontinued; (3) the property is available for immediate sale in its present condition; (4) actions required to complete the sale of the property have been initiated; (5) sale of the property is probable and we expect the completed sale will occur within one year; and (6) the property is actively being marketed for sale at a price that is reasonable given our estimate of current market value. Upon designation of a property as an asset held for sale, we record the property’s value at the lower of its carrying value or its estimated fair value, less estimated costs to sell, and we cease depreciation. Lessee Accounting Omega leases real estate (corporate headquarters and certain other facilities), office equipment and is party to certain ground leases on our owned facilities. We determine if an arrangement is or contains a lease at inception. Leases are classified as either finance or operating at inception of the lease. Short-term leases, defined as leases with an initial term of 12 months or less that do not contain a purchase option, are not recorded on the balance sheet. Lease expense for short-term leases is recognized on a straight-line basis over the lease term. As of December 31, 2022 and 2021, all of the leases where we are the lessee were classified as operating leases. We have leases that contain both lease and non-lease components and have elected, as an accounting policy, to not separate lease components and non-lease components. Operating and finance lease right-of-use ("ROU") assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Our ROU assets and lease liabilities are included in other assets and accrued expenses and other liabilities, respectively, on our Consolidated Balance Sheets. The lease liability is calculated as the present value of the remaining minimum rental payments for existing leases using either the rate implicit in the lease or, if none exists, the Company's incremental borrowing rate, as the discount rate. Certain leases have options to extend, terminate or purchase the asset and have been considered in our analysis of the lease term and the measurement of the ROU assets and lease liabilities. On a quarterly basis, we record our lease liabilities at the present value of the future lease payments using the discount rate determined at lease commencement. Rental expense from operating leases is generally recognized on a straight-line basis over the lease term. Lease expense derived from our operating leases is recorded in general and administrative in our Consolidated Statements of Operations. We do not include in our measurement of our lease liability certain variable payments, including changes in an index until the specific events that trigger the variable payments have occurred. We record on a straight-line basis rental income and ground lease expense for those assets we lease and are reimbursed by our operators and/or are paid for directly by our operators. In-Place Leases In-place lease assets and liabilities result when we assume a lease as part of an asset acquisition or business combination. The fair value of in-place leases consists of the following components, as applicable (1) the estimated cost to replace the leases and (2) the above or below market cash flow of the leases, determined by comparing the projected cash flows of the leases in place at the time of acquisition to projected cash flows of comparable market-rate leases. Above market leases, net of accumulated amortization, are included in other assets on our Consolidated Balance Sheets. Below market leases, net of accumulated amortization, are included in accrued expenses and other liabilities on our Consolidated Balance Sheets. The net amortization related to the above and below market leases is included in our Consolidated Statements of Operations as an adjustment to rental income over the estimated remaining term of the underlying leases. Should a tenant terminate the lease, the unamortized portion of the lease intangible is recognized immediately as an adjustment to rental income. Allowance for Credit Losses The allowance for credit losses reflects our current estimate of the potential credit losses on our real estate loans, non-real estate loans, and our investment in direct financing leases and is recorded as a valuation account as a direct offset against these financial instruments on our Consolidated Balance Sheets. Expected credit losses inherent in non-cancelable unfunded loan commitments are accounted for as separate liabilities included in accrued expenses and other liabilities on the Consolidated Balance Sheets. The Company has elected to not measure an allowance for credit losses on accrued interest receivables related to all of its real estate loans and non-real estate loans because we write off uncollectible accrued interest receivable in a timely manner pursuant to our non-accrual policy, described below. Changes to the allowance for credit losses on loans resulting from quarterly evaluations are recorded through provision for credit losses on the Consolidated Statements of Operations. We assess the creditworthiness of our borrowers on a quarterly basis. For purposes of determining our allowance for credit loss, we pool financial assets that have similar risk characteristics. We aggregate our financial assets by financial instrument type (i.e. real estate loan, non-real estate loan, etc.) and by our internal risk rating. Our internal credit ratings consider several factors including the collateral and/or security, the performance of borrowers underlying facilities, if applicable, available credit support (e.g., guarantees), borrowings with third parties, and other ancillary business ventures and real estate operations of the borrower. Our internal ratings range between 1 and 7. An internal rating of 1 reflects the lowest likelihood of loss and a 7 reflects the highest likelihood of loss. The characteristics associated with each risk rating is as follows: ● Risk Rating 1 through 3 – Instruments with minimal to marginally acceptable risk. ● Risk Rating 4 - Instruments with potential weaknesses identified (Special mention). ● Risk Rating 5 - Instruments with well-defined weaknesses that may result in possible losses (Substandard). ● Risk Rating 6 – Instruments that are unlikely to be repaid in full and will probably result in losses (Doubtful). ● Risk Rating 7 – Instrument that will not be repaid in full and losses will occur (Loss). Periodically, the Company may identify an individual loan for impairment. A loan is considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due as scheduled according to the contractual terms of the loan agreements. Our assessment of collectibility considers several factors, including, among other things, payment history, the financial strength of the borrower and any guarantors, historical operations and operating trends, current and future economic conditions, expectations of performance (which includes known substantial doubt about an operator’s ability to continue as a going concern) and the fair value of the underlying collateral of the agreement, a Level 3 measurement, if any. Consistent with this definition, all loans on non-accrual status may be deemed impaired. To the extent circumstances improve and the risk of collectibility is diminished, we will return these loans to full accrual status. When we identify a loan impairment, the loan is written down to the present value of the expected future cash flows or to the fair value of the underlying collateral. Financial instruments are charged off against the allowance for credit losses when collectibility is determined to be permanently impaired. We account for impaired loans using (a) the cost-recovery method, and/or (b) the cash basis method. We generally utilize the cost-recovery method for impaired loans for which impairment reserves were recorded. Under the cost-recovery method, we apply cash received against the outstanding loan balance prior to recording interest income. Under the cash basis method, we apply cash received to principal or interest income based on the terms of the agreement. Investments in Unconsolidated Joint Ventures We account for our investments in unconsolidated joint ventures using the equity method of accounting as we exercise significant influence, but do not control the entities. Under the equity method of accounting, the net equity investments of the Company are reflected in the accompanying Consolidated Balance Sheets and the Company’s share of net income and comprehensive income from the joint ventures are included in the accompanying Consolidated Statements of Operations and Consolidated Statements of Comprehensive Income, respectively. On a periodic basis, management assesses whether there are any indicators that the value of the Company’s investments in the unconsolidated joint ventures may be other-than-temporarily-impaired. An investment is impaired only if management’s estimate of the value of the investment is less than the carrying value of the investment, and such a decline in value is deemed to be other than-temporary. To the extent impairment has occurred, the loss is measured as the excess of the carrying amount of the investment over the estimated fair value of the investment. The estimated fair value of the investment is determined using a discounted cash flow model which is a Level 3 valuation. We consider a number of assumptions that are subject to economic and market uncertainties including, among others, rental rates, operating costs, capitalization rates, holding periods and discount rates. No impairment losses on our investments in unconsolidated joint ventures were recognized for the last three fiscal years. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and highly liquid investments with a maturity date of three months or less when purchased. These investments are stated at cost, which approximates fair value. The majority of our cash, cash equivalents and restricted cash are held at major commercial banks. Certain cash account balances exceed FDIC insurance limits of $250,000 per account and, as a result, there is a concentration of credit risk related to amounts in excess of the insurance limits. We regularly monitor the financial stability of these financial institutions and believe that we are not exposed to any significant credit risk in cash, cash equivalents or restricted cash. Restricted Cash Restricted cash consists primarily of liquidity deposits escrowed for tenant obligations required by us pursuant to certain contractual terms and other deposits required by the U.S. Department of Housing and Urban Development (“HUD”) in connection with our mortgage borrowings guaranteed by HUD. Deposits We obtain liquidity deposits and other deposits, security deposits and letters of credit from certain operators pursuant to our lease and mortgage agreements. These generally represent the rental and/or mortgage interest for periods ranging from three The liquidity deposits and other deposits, security deposits and the letters of credit may be used in the event of lease and/or loan defaults, subject to applicable limitations under bankruptcy law with respect to operators filing under Chapter 11 of the U.S. Bankruptcy Code. Liquidity deposits and other deposits are recorded as restricted cash on our Consolidated Balance Sheets with the offset recorded as a liability in accrued expenses and other liabilities on our Consolidated Balance Sheets. Security deposits related to cash received from the operators are primarily recorded in cash and cash equivalents on our Consolidated Balance Sheets with a corresponding offset in accrued expenses and other liabilities on our Consolidated Balance Sheets. Additional security for rental and loan interest revenue from operators is provided by covenants regarding minimum working capital and net worth, liens on accounts receivable and other operating assets of the operators, provisions for cross-default, provisions for cross-collateralization and by corporate or personal guarantees. Goodwill Impairment We test goodwill for potential impairment at least annually in the fourth quarter, or more frequently if an event or other circumstance indicates that we may not be able to recover the carrying amount of the net assets of the reporting unit. In evaluating goodwill for impairment, we may assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If we bypass the qualitative assessment, or if we conclude that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then we p

REAL ESTATE ASSET ACQUISITIONS AND DEVELOPMENTTS	NOTE 3 – REAL ESTATE ASSET ACQUISITIONS AND DEVELOPMENT 2022 Acquisitions The following table summarizes the significant asset acquisitions that occurred in 2022: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Number of ​ ​ ​ Total Real Estate ​ Initial ​ ​ Facilities ​ Assets Acquired Annual ​ Period ​ SNF ALF ​ Country/State ​ (in millions) ​ Cash Yield (1) ​ Q1 — 1 U.K. ​ $ 8.7 (2) 8.0 % Q1 ​ — 1 ​ U.K. ​ ​ 5.0 ​ 8.0 % Q1 ​ — 27 ​ U.K. ​ ​ 86.6 (2) 8.0 % Q1 ​ 1 — ​ MD ​ ​ 8.2 (3) 9.5 % Q3 ​ — 4 ​ U.K. ​ ​ 28.2 ​ 8.0 % Q4 ​ 6 1 ​ PA, NC ​ ​ 88.5 (4) 9.0 % Total 7 34 ​ $ 225.2 ​ ​ (1) Initial annual cash yield reflects the initial annual contractual cash rent divided by the purchase price. (2) The total consideration paid for the one -facility U.K. acquisition and the 27 -facility U.K. acquisition was $8.2 million and $100.0 million, respectively . In connection with these acquisitions, we allocated $0.5 million of the purchase consideration to a deferred tax liability related to the one -facility U.K. acquisition, and $13.4 million to a deferred tax asset related to the 27 -facility U.K. acquisition. See Note 17 – Taxes for additional information. (3) Total consideration for the one -facility Maryland acquisition was paid on December 30, 2021, but the closing of the acquisition did not occur until January 1, 2022. (4) During the fourth quarter of 2022, we acquired seven facilities using a reverse like-kind exchange structure pursuant to Section 1031 of the Code (a “reverse 1031 exchange”). As of December 31, 2022, we had completed the reverse 1031 exchange for three of the acquired facilities and the remaining four acquired facilities remained in the possession of the EATs. The EATs were classified as VIEs as they do not have sufficient equity investment at risk to permit the entity to finance its activities. The Company consolidated the EATs because it had the ability to control the activities that most significantly impacted the economic performance of the EATs and was, therefore, the primary beneficiary of the EATs. The properties held by the EATs were reflected as real estate with a carrying value of $55.2 million as of December 31, 2022. The EATs also held cash of $23.9 million as of December 31, 2022. 2021 Acquisitions and Other The following table summarizes the significant asset acquisitions that occurred in 2021: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Number of ​ ​ ​ Total Real Estate ​ Initial ​ ​ Facilities ​ Assets Acquired (1) Annual ​ Period ​ SNF ALF Specialty ​ Country/State ​ (in millions) ​ Cash Yield (2) ​ Q1 — 17 7 AZ, CA, FL, IL, NJ, OR, PA, TN, TX, VA, WA ​ $ 511.3 ​ 8.43 % Q1 ​ 6 — — ​ FL ​ ​ 83.1 ​ 9.25 % Q3 ​ — 2 — ​ U.K. ​ ​ 9.6 ​ 7.89 % Total 6 19 7 ​ $ 604.0 ​ ​ (1) Excludes $10.6 million of land acquisitions, $58.6 million of non-cash acquisitions of facilities previously subject to mortgage loans with Omega in which principal amounts under the loan agreements were reduced or settled in exchange for title to the facilities (See Note 7 – Real Estate Loans Receivable), and $1.2 million of transaction costs incurred related to the non-cash acquisitions. (2) Initial annual cash yield reflects the initial annual contractual cash rent divided by the purchase price. On January 20, 2021, we acquired 24 senior living facilities from Healthpeak Properties, Inc. for $511.3 million. The acquisition involved the assumption of an in-place master lease with Brookdale Senior Living Inc. We recognized approximately $45.0 million of rental income for the year ended December 31, 2021 under this master lease, which includes 24 facilities representing 2,552 operating units. 2020 Acquisitions The following table summarizes the significant transactions that occurred in 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Number of ​ ​ ​ Total Real Estate ​ ​ Initial ​ ​ Facilities ​ Assets Acquired Annual ​ Period ​ SNF ALF ​ Country/State ​ (in millions) ​ ​ Cash Yield (1) ​ Q1 — 2 U.K ​ $ 12.1 ​ 8.00 % Q1 1 — IN ​ 7.0 ​ 9.50 % Q2 1 — OH ​ 6.9 ​ 9.50 % Q4 ​ 6 1 VA ​ 78.4 ​ 9.50 % Total 8 3 ​ $ 104.4 ​ ​ (1) Initial annual cash yield reflects the initial annual contractual cash rent divided by the purchase price. ​ Construction in progress and capital expenditure investments We invested $64.4 million, $140.0 million and $106.2 million, respectively under our construction in progress and capital improvement programs during the years ended December 31, 2022, 2021 and 2020. In the second quarter of 2021, we placed a $41.1 million construction project for a new build ALF in New Jersey into service and began recognizing revenue associated with this project in the third quarter of 2021. The lease for this facility provides for an annual cash yield of 7% of the amount funded in the first year following the completion of construction increasing to 8% in year two with 2.5% annual escalators thereafter. During the third quarter of 2021, we purchased a real estate property located in Washington, D.C. (not reflected in the table above) for approximately $68.0 million and plan to redevelop the property into a 174 bed ALF. Concurrent with the acquisition, we entered into a single facility lease for this property with Maplewood Senior Living (along with affiliates, “Maplewood”) through August 31, 2045. For accounting purposes, the lease will commence upon the substantial completion of construction of the ALF, which is currently expected to be in 2025. The lease provides for the accrual of financing costs at a rate of 5% per annum during the construction phase. The lease provides for an annual cash yield of 6% in the first year following the completion of construction, increasing to 7% in year two and 8% in year three with 2.5% annual escalators thereafter. We are committed to a maximum funding of $177.7 million for the redevelopment of the real estate property, subject to ordinary development related cost changes (see Note 20 - Commitments and Contingencies) .

ASSETS HELD FOR SALE, DISPOSITIONS AND IMPAIRMENTS [Abstract]
ASSETS HELD FOR SALE, DISPOSITIONS AND IMPAIRMENTS	NOTE 4 – ASSETS HELD FOR SALE, DISPOSITIONS AND IMPAIRMENTS We periodically sell facilities to reduce our concentration in certain operators, geographies and non-strategic assets or due to the exercise of a tenant purchase option. The following is a summary of our assets held for sale: ​ ​ ​ ​ ​ ​ ​ December 31, ​ December 31, ​ 2022 2021 Number of facilities held for sale ​ 2 ​ ​ 28 Amount of assets held for sale (in thousands) $ 9,456 ​ $ 203,025 ​ In the fourth quarter of 2022, we reclassified 13 facilities with aggregate net book values of $58.1 million, from assets held for sale to assets held for use within the applicable line items in real estate assets – net. Of the $58.1 million reclassified net of $20.8 million of accumulated depreciation, $67.5 million relates to buildings, $2.8 million relates to land and $8.6 relates to furniture and equipment. We originally reclassified these facilities as held for sale in the fourth quarter of 2021, but we no longer believe these facilities qualify as assets held for sale. We recorded a $3.2 million cumulative catch-up adjustment to depreciation and amortization expense related to these facilities concurrent with the reclassification in the fourth quarter of 2022. One of the two facilities that were classified as held for sale as of December 31, 2022 was subsequently sold during the first quarter of 2023 for gross cash proceeds of $19.5 million. Asset Sales 2022 Activity During the year ended December 31, 2022, we sold 66 facilities subject to operating leases for approximately $759.0 million in net cash proceeds, recognizing a net gain of approximately $360.0 million. Our 2022 sales were primarily driven by restructuring transactions and negotiations related to our lease agreements with the following operators: Gulf Coast Health Care LLC (together with certain affiliates “Gulf Coast”), Guardian Healthcare (“Guardian”) and Agemo Holdings, LLC (“Agemo”). In addition, during the fourth quarter of 2022, we sold 11 facilities previously leased to and operated by LaVie which did not meet the contract criteria to be recognized under ASC 610-20, further discussed below, and as such are not included in the amounts above. In the first quarter of 2022, we sold 22 facilities that were previously leased and operated by Gulf Coast. The net cash proceeds from the sale, including related costs accrued for as of the end of the fourth quarter, were $304.9 million, and we recognized a net gain of $114.5 million. The agreement includes an earnout clause pursuant to which the buyer is obligated to pay an additional $18.7 million to Omega if certain financial metrics are achieved at the facilities in the three years following the sale. As we have determined it is not probable that we will receive any additional funds, we have not recorded any income related to the earnout clause. During the first and second quarter of 2022, we sold nine total facilities that were leased to Guardian for $39.5 million in net proceeds, which resulted in a net gain of $13.7 million. In the third and fourth quarter of 2022, we sold 22 facilities that were previously leased to Agemo for $358.7 million in net proceeds, which resulted in a net gain of $218.9 million. In December 2022, in connection with restructuring negotiations with LaVie, we sold 11 facilities to a third party previously leased to LaVie for a sales price of $129.8 million. Omega provided $104.8 million in senior seller financing, collateralized by first lien mortgages on the 11 facilities, to fund a portion of the purchase price. The senior note has a December 29, 2027 maturity date and bears interest at 8% with required monthly interest payments (due in arrears beginning February 1, 2023), with no principal payments due until the maturity date. The remaining consideration received under the purchase agreement is the assumption of a $25.0 million liability by the buyer from Omega. The 11-facility sale does not meet the contract criteria to be recognized under ASC 610-20 and we will continue to account for these facilities on our Consolidated Balance Sheets and depreciate the facilities until the recognition requirements under ASC 610-20 are met. A contract liability was recorded and related expense of $25.0 million was recognized on our Consolidated Balance Sheets within accrued expenses and other liabilities and Consolidated Statements of Operations within acquisition, merger and transition costs, respectively. The liability will be relieved once the sale is recognized. The loan receivable associated with the seller financing will not be recorded on our Consolidated Balance Sheets until the sale is recognized, and any cash interest received will be deferred and recorded as a contract liability within accrued expenses and other liabilities on our Consolidated Balance Sheets. 2021 Activity During the year ended December 31, 2021, we sold 48 facilities for approximately $318.5 million in net cash proceeds, recognizing a net gain of approximately $161.6 million. 2020 Activity During the year ended December 31, 2020, we sold 43 facilities for approximately $180.9 million in net cash proceeds, recognizing a net gain of approximately $19.1 million. Real Estate Impairments 2022 Activity During the year ended December 31, 2022, we recorded impairments of approximately $38.5 million on 22 facilities. Of the $38.5 million, $3.5 million related to two facilities that were classified as held for sale (and subsequently sold) for which the carrying values exceeded the estimated fair values less costs to sell, and $35.0 million related to 20 held-for-use facilities for which the carrying value exceeded the fair value, of which $17.2 million relates to 12 facilities leased to and operated by LaVie that are expected to be impacted by the on-going restructuring negotiations. $10.0 million of the 2022 impairments recorded on four held-for-use facilities relate to the 2.0% Operator discussed in Note 5 – Contractual Receivables and Other Receivables and Lease Inducements. 2021 Activity During the year ended December 31, 2021, we recorded impairments of approximately $44.7 million on 14 facilities which were sold or classified as held for sale for which the carrying values exceeded the estimated fair values less costs to sell. 2020 Activity During the year ended December 31, 2020, we recorded impairments of approximately $76.0 million on 25 facilities. Our impairments were offset by approximately $3.5 million of insurance proceeds received related to a facility that was previously destroyed and impaired. Of the $76.0 million, $41.5 million related to 14 facilities which were sold or classified as held for sale for which the carrying values exceeded the estimated fair values less costs to sell, and $34.5 million related to 11 held-for-use facilities for which it was determined that the carrying value exceeded the fair value. The $34.5 million relates to facilities subject to a lease with Daybreak Ventures, LLC (“Daybreak”) (see Note 5 – Contractual Receivables and Other Receivables and Lease Inducements), which were planned for resale or transitioned to another existing operator and it was determined that the new cash flows were not sufficient to support the carrying value of the facility.

CONTRACTUAL RECEIVABLES AND OTHER RECEIVABLES AND LEASE INDUCEMENTS [Abstract]
CONTRACTUAL RECEIVABLES AND OTHER RECEIVABLES AND LEASE INDUCEMENTS	NOTE 5 – CONTRACTUAL RECEIVABLES AND OTHER RECEIVABLES AND LEASE INDUCEMENTS Contractual receivables relate to the amounts currently owed to us under the terms of our lease and loan agreements. Effective yield interest receivables relate to the difference between the interest income recognized on an effective yield basis over the term of the loan agreement and the interest currently due to us according to the contractual agreement. Straight-line rent receivables relate to the difference between the rental revenue recognized on a straight-line basis and the amounts currently due to us according to the contractual agreement. Lease inducements result from value provided by us to the lessee, at the inception, modification or renewal of the lease, and are amortized as a reduction of rental income over the non-cancellable lease term. A summary of our net receivables by type is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ December 31, ​ ​ 2022 2021 ​ ​ (in thousands) ​ Contractual receivables – net ​ $ 8,228 ​ $ 11,259 ​ ​ ​ ​ ​ ​ ​ ​ ​ Effective yield interest receivables ​ $ 5,696 ​ $ 9,590 ​ Straight-line rent receivables ​ 166,061 ​ 148,455 ​ Lease inducements ​ 6,041 ​ 93,770 ​ Other receivables and lease inducements ​ $ 177,798 ​ $ 251,815 ​ ​ Cash basis operators and straight-line receivable write-offs We review our collectibility assumptions related to our operator leases on an ongoing basis. During the years ended December 31, 2022, 2021 and 2020, we placed nine, six and four additional operators on a cash basis of revenue recognition, respectively, as collection of substantially all contractual lease payments due from them was no longer deemed probable. In connection with placing these operators on a cash basis, we recognized $119.8 million, $36.0 million and $129.5 million in total straight-line accounts receivable and lease inducement write-offs through rental income during the years ended December 31, 2022, 2021 and 2020, respectively. As of December 31, 2022, we had 20 operators on a cash basis for revenue recognition, which represent 36.5%, 39.2% and 41.5% of our total revenues (excluding the impact of write-offs) for the years ended December 31, 2022, 2021 and 2020, respectively. As of December 31, 2021, we had 14 operators on a cash basis for revenue recognition, which represent 18.6% and 22.7% of our total revenues (excluding the impact of write-offs) for the years ended December 31, 2021 and 2020, respectively. During the years ended December 31, 2022, 2021 and 2020, we also wrote-off $3.2 million, $1.3 million and $3.6 million of straight-line rent receivable balances through rental income as a result of transitioning facilities between existing operators. Operator updates Agemo Agemo was formed in May 2018 by Signature Healthcare, LLC, as part of an out-of-court restructuring agreement, to be the holding company of their leases and loans with Omega. As part of that restructuring agreement, we agreed to, among other things, allow for the deferral of $6.3 million of rent per annum for a 3-year period (the “Agemo Rent Deferral”). We placed Agemo on a cash basis of revenue recognition during the third quarter of 2020 as we received information regarding substantial doubt of their ability to continue as a going concern. As a result, we wrote-off approximately $13.4 million of contractual rent receivables and $61.9 million of straight-line rent receivables and lease inducements. Agemo continued to make their rental and interest payments to us until July 2021. After July 2021, Agemo made one month of contractual rent and interest payments for the remainder of fiscal year 2021. During the third and fourth quarters of 2021, we recorded $8.7 million of revenue by collecting rental and interest payments and we recorded $8.5 million of revenue by drawing on a letter of credit and through application of collateral held by Omega. On September 30, 2021, the Company entered into a forbearance agreement related to Agemo’s defaults under its lease and loan agreements (the “Agemo Forbearance Agreement”), which was amended to extend the forbearance period through January 2022 and the lease agreement was amended to extend the Agemo Rent Deferral through January 2022. Agemo continued to not pay contractual rent and interest due under its lease and loan agreements during the year ended December 31, 2022. No rental income was recorded related to Agemo during the year ended December 31, 2022. Additionally, no interest income was recognized during the year ended December 31, 2022 on the two loans with Agemo because these loans are on non-accrual status and we are utilizing the cost recovery method, under which any payments, if received, are applied against the principal amount. See Note 8 – Non-real Estate Loans Receivable for additional details on our loans with Agemo. For the years ended December 31, 2021 and 2020, Agemo generated approximately 3.9% and 5.6%, respectively, of our total revenues (excluding the impact of write-offs). The Agemo Forbearance Agreement has been amended multiple times throughout 2022 and the most recent 2022 amendment on December 30, 2022 extended the forbearance period through January 31, 2023 In the first quarter of 2023, Omega and Agemo entered into a restructuring agreement, an amended and restated master lease and a replacement loan agreement for two replacement loans. As part of the restructuring agreement and related agreements, Omega agreed to, among other things: ● Forgive and release Agemo from previously written off past due rent and interest obligations related to certain periods prior to the 2018 Restructuring and from August 2021 through January 2023, with contractual rent under the lease agreement and contractual interest under the loan agreements scheduled to resume on April 1, 2023; ● reduce monthly contractual base rent from $4.8 million to $1.9 million following the sales of the 22 facilities, previously leased and operated by Agemo, that occurred in the third and fourth quarters of 2022 (See Note 4 – Assets Held For Sale, Dispositions and Impairments); ● extend the initial Agemo lease term from December 31, 2030 , to December 31, 2036 with three consecutive tenant 10-year extension options; and ● refinance and restructure the $25.0 million secured working capital loan (the “Agemo WC Loan”), the $32.0 million term loan (the “Agemo Term Loan”) and the aggregate deferred rent balance of $25.2 million into two replacement loans to Agemo that mature on December 31, 2036, with aggregate principal of $82.2 million and an annual interest rate of 5.71% . Guardian Guardian did not make rent and interest payments under its lease and mortgage loan agreements during the fourth quarter of 2021. As a result of Guardian’s non-payment of contractual rent and the anticipated restructuring of its agreements, in the fourth quarter of 2021, we placed Guardian on a cash basis of revenue recognition and wrote-off approximately $14.0 million of straight-line rent receivables and lease inducements through rental income. In the fourth quarter of 2021, we began negotiations to restructure Guardian’s lease and loan agreements. In connection with the restructuring negotiations, on December 30, 2021, we acquired 2 facilities, previously subject to the Guardian mortgage loan, in consideration for a reduction of $8.7 million in the mortgage principal and added the facilities to the master lease agreement. ● Extend the lease and loan maturity dates from January 31, 2027 to December 31, 2031 and allow Guardian the option to extend the maturity date for both the lease and loan through September 30, 2034 , subject to certain conditions; ● reduce the combined rent and mortgage interest to an aggregate $24.0 million per year as of July 1, 2022 ( $15.0 million in rent and $9.0 million in interest) with annual escalators of 2.25% beginning in January 2023; and ● allow Guardian to retrospectively defer $18.0 million of aggregate contractual rent and interest that it failed to pay from October 2021 through March 2022 (consisting of $12.2 million of deferred rent and $5.8 million of deferred interest), with repayment required beginning after September 30, 2024, based on certain financial metrics, and in full by December 31, 2031, or the earlier termination of the lease for any reason. Following the execution of the restructuring agreement, Guardian resumed paying contractual rent and interest during the second quarter of 2022 and continued such payments in the third and fourth quarters of 2022, in accordance with the restructuring terms. For the year ended December 31, 2022, we recorded rental income of $11.3 million for the contractual rent payments that were received. Additionally, as discussed further in Note 7 – Real Estate Loans Receivable, no mortgage interest income has been recognized on the Guardian mortgage loan during the year ended December 31, 2022, as we are accounting for this loan under the cost recovery method. Revenue from Guardian represents approximately 1.1%, 2.5% and 3.5% of our total revenues (excluding the impact of straight-line write-offs) for the years ended December 31, 2022, 2021 and 2020, respectively. As of December 31, 2022, we have $7.4 million of letters of credit from Guardian as collateral. LaVie In the fourth quarter of 2022, Omega began the process of restructuring our portfolio with LaVie, which primarily consists of two master lease agreements and two term loan agreements. On December 30, 2022, we sold 11 facilities previously subject to one of the two leases agreements with LaVie. See further discussion on the sale and the accounting treatment in Note 4 -Assets Held For Sale, Dispositions and Impairments. Concurrent with the sale, we also amended the lease agreement impacted by the sale and our loan agreements with LaVie. The amendments to the loan agreements are discussed in Note 8 – Non-Real Estate Loans. With the lease amendment and other related documents, Omega and LaVie agreed to, among other terms: ​ ● Remove the 11 sold facilities from the lease agreement and reduce monthly contractual rent due under all agreements from $8.3 million to $7.3 million; ● provide Omega the ability to enact a one-time rent reset on one of the lease agreements, if LaVie’s coverage exceeds a threshold, after February 1, 2027; and ● require Omega to pay LaVie a $35.0 million termination fee in connection with transitioning the 11 facilities sold in the fourth quarter and the additional facilities sold in the restructure ( $25.0 million was assumed by the third-party buyer of the 11 facilities). The restructuring discussions are still ongoing and subject to change, but we anticipate additional restructuring activity related to this operator in 2023. As a result of the restructuring activities during 2022 and future expected restructuring activities, during the fourth quarter of 2022, we placed LaVie on a cash basis of revenue recognition and wrote-off approximately $58.0 million of straight-line rent receivables and lease inducements. Revenue from LaVie represents approximately 11.1%, 9.5% and 9.4% of our total revenues (excluding the impact of straight-line write-offs) for the years ended December 31, 2022, 2021 and 2020, respectively. In the first quarter of 2023, as part of the restructuring, we have agreed to a partial rent deferral in the first four months of 2023. In doing so, we agreed to allow LaVie to defer up to $10.0 million of contractual rent from January 2023 through April 2023 under one of our lease agreements for 32 facilities. Omega is in discussions to allow LaVie to defer up to $9.1 million of contractual rent from January 2023 through April 2023 under another lease agreement for 41 facilities. In January 2023, as a result, LaVie deferred the full contractual payment of $2.5 million under the 32-facility lease and paid $2.5 million of the $4.7 million of contractual rent due under the 41-facility lease. Maplewood During the year ended December 31, 2020, we received a one-time rent payment of approximately $55.4 million from Maplewood, in conjunction with the restructuring of its master lease and loans with Omega (see Note 8 – Non-real Estate Loans Receivable). This payment was accounted for as an adjustment to straight-line rent receivables and was being amortized over the remaining term of the master lease prior to Maplewood being placed on a cash basis of revenue recognition in the fourth quarter of 2022. During the fourth quarter of 2022, Omega began discussions with Maplewood to restructure their portfolio, which includes a lease agreement and $250.5 million revolving credit facility. During the fourth quarter of 2022, we placed Maplewood on a cash basis of revenue recognition and wrote-off approximately $29.3 million of straight-line rent receivables and lease inducements. Revenue from Maplewood represents approximately 8.9%, 7.9% and 5.3% of our total revenues (excluding the impact of straight-line write-offs) for the years ended December 31, 2022, 2021 and 2020, respectively. In the first quarter of 2023, we agreed to a formal restructuring agreement, master lease amendments and loan amendments with Maplewood. As part of the restructuring agreement and related agreements, Omega agreed to, among other things: ● Extend the maturity date of the master lease from December 2033 to December 2037 with two consecutive 5-year tenant extension options; ● fix contractual rent at $69.3 million per annum (December 2022 rent annualized) and defer the 2.5% annual escalators under our lease agreement through December 31, 2025, with mandatory repayments to be made subject to certain metrics and due in full by the maturity date; ● fund $22.5 million of capital expenditures through December 31, 2025; ● extend the maturity date of the secured revolving credit facility from June 2030 to June 2035 with one borrower 2-year extension option; ● increase the capacity of the secured revolving credit facility from $250.5 million to $320.0 million, inclusive of payment-in-kind (“PIK”) interest applied to principal ; ● convert the 7% per annum cash interest due on the secured revolving credit facility to all PIK interest in 2023, 1% cash interest and 6% PIK interest in 2024, 4% cash interest and 3% PIK interest in 2025 and through the maturity date; and ● reduce Maplewood’s share of any future potential sales proceeds (in excess of our gross investment) by the unpaid deferred rent balance and the $22.5 million of capital expenditures. Gulf Coast During the second quarter of 2021, Gulf Coast stopped paying contractual rent under its master lease agreement because of on-going liquidity issues. Gulf Coast operated 24 facilities subject to a master lease with Omega and represented approximately 3.3% and 2.8% of Omega’s total revenues (excluding the impact of write-offs) for the years ended December 31, 2021 and 2020, respectively. As a result of Gulf Coast’s default under its master lease agreement, in August 2021, we exercised our right to accelerate the full amount of rent due under Gulf Coast’s master lease agreement. On October 14, 2021, Gulf Coast commenced voluntary cases under Chapter 11 of the U.S. Bankruptcy Code in the U.S. Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”). As described in Gulf Coast’s filings with the Bankruptcy Court, we entered into a Restructuring Support Agreement (the “Support Agreement”) that forms the basis for Gulf Coast’s restructuring and liquidation. The Support Agreement established a timeline for the implementation of Gulf Coast’s restructuring and liquidation, including the transition of management of the operations of the facilities to a third-party operator. As part of the Support Agreement, we committed to provide up to $25 million of senior secured debtor-in-possession (“DIP”) financing to Gulf Coast, which is discussed in further detail in Note 8 – Non-real Estate Loans Receivable. In November 2021, Gulf Coast entered into management and operations transfer agreements (“MOTAs”) with a new manager (“New Manager”), pursuant to which the management of 23 of the 24 facilities subject to the master lease with Omega were performed by New Manager during an interim period until the license for the facilities subject to the MOTAs could be obtained by a new operator (“New Operator”). During the interim period, no rent was being paid by Gulf Coast, and we have provided a $20 million working capital loan to New Manager, discussed in further detail in Note 8 – Non-real Estate Loans Receivable. The Bankruptcy Court approved the MOTAs on November 24, 2021 and the operations were transitioned effective December 1, 2021. On June 27, 2022, the Bankruptcy Court entered its order confirming Gulf Coast’s bankruptcy plan which provided for, among other things, an allowed claim of $49.0 million in relation to the accelerated rent due under Gulf Coast’s master lease agreement. Payment of the allowed claim has been redirected, with Omega’s approval, under the Plan to Gulf Coast’s unsecured creditors. As a result of Gulf Coast’s non-payment of contractual rent, in the second quarter of 2021, we placed Gulf Coast on a cash basis of revenue recognition and wrote-off straight-line rent receivable balances of $17.4 million through rental income. Subsequent to placing Gulf Coast on a cash basis of revenue recognition in June 2021, we recognized $24.6 million of rental income over the remaining period of 2021, based on our ability to offset any uncollected rent receivables against Gulf Coast’s security deposit and against certain debt obligations of Omega, as discussed further below. We held a security deposit of $3.3 million from Gulf Coast, which we applied against Gulf Coast’s obligations in the second and third quarters of 2021. In relation to Gulf Coast, a subsidiary of Omega (“Omega Obligor”) is the obligor on five notes due to third parties with aggregate outstanding principal of $20.0 million (collectively, the “Subordinated Debt”) that bear interest at 9% per annum with a maturity date of December 21, 2021 (see Note 14 – Borrowing Activities and Arrangements). Under the terms of the Subordinated Debt, to the extent Gulf Coast fails to pay rent when due to us under its master lease, Gulf Coast’s unpaid rent can be used to offset Omega Obligor’s obligations under the Subordinated Debt (on a quarterly basis with respect to interest and, under some circumstances, on an annual basis with respect to principal). As of December 31, 2021, we have offset $1.3 million of accrued interest and $20.0 million of principal under the Subordinated Debt against the uncollected rent under the master lease with Gulf Coast. Following the application of these offsets, Omega has no further obligations under the Subordinated Debt. See Note 20 – Commitments and Contingencies for additional discussion regarding an ongoing lawsuit related to the Subordinated Debt. As discussed in Note 4 – Assets Held For Sale, Dispositions and Impairments, we sold 22 facilities that were previously leased and operated by Gulf Coast in the first quarter of 2022. We transitioned one facility that was previously leased and operated by Gulf Coast to another operator in the second quarter of 2022. Daybreak Daybreak previously leased and operated 58 facilities from Omega. During the third quarter of 2017, we placed Daybreak on a cash basis for revenue recognition as a result of nonpayment of funds owed to us. We elected to terminate our relationship with Daybreak and we transitioned 31 Daybreak facilities to existing operators during 2020. The total annual contractual rent from the 31 transitioned facilities was approximately $12.4 million. In 2021, we transitioned 14 additional facilities to existing operators with annual contractual rent of approximately $4.0 million and sold the remaining four Daybreak facilities. The transition and sale of these facilities completed our exit from our relationship with Daybreak. Genesis Healthcare, Inc. During the year ended December 31, 2020, we wrote-off approximately $64.9 million of contractual receivables, straight-line rent receivables, and lease inducements through rental income in 2020 as a result of placing Genesis Healthcare, Inc. (“Genesis”) on a cash basis based on information the Company received from Genesis during the third quarter of 2020 regarding substantial doubt as to their ability to continue as a going concern. Genesis represents approximately 6.6%, 5.9% and 7.6%, respectively, of our total revenues (excluding the impact of write-offs) for the years ended December 31, 2022, 2021 and 2020. Genesis continued to make their rental and interest payments to us during the years ended December 31, 2022, 2021 and 2020. 3.7% Operator From January through March 2022, an operator (the “3.7% Operator”) representing 3.7%, 3.4% and 3.1% of total revenue (excluding the impact of write-offs) for the years ended December 31, 2022, 2021 and 2020, respectively, did not pay its contractual amounts due under its lease agreement. In March 2022, the lease with the 3.7% Operator was amended to allow for a short-term rent deferral for January through March 2022. The deferred rent balance accrues interest monthly at a rate of 5% per annum. The 3.7% Operator paid the contractual amount due under its lease agreement from April 2022 through December 2022. Omega holds a $1.0 million letter of credit and a $150 thousand security deposit from the 3.7% Operator as collateral under its lease agreement. The 3.7% Operator remains on a straight-line basis of revenue recognition. We have a revolving credit facility with the 3.7% Operator, that was amended in the fourth quarter of 2022 to increase the capacity to $25.0 million, that is fully drawn as of December 31, 2022. The credit facility is secured by a first lien on the accounts receivable of the 3.7% Operator. The 3.7% Operator paid contractual interest under the facility from January through December 2022. See Note 8 – Non-Real Estate Loans Receivable for additional details. 1.2% Operator In March 2022, an operator (the “1.2% Operator”), representing 1.2%, 2.1% and 2.5% of total revenue (excluding the impact of write-offs) for the years ended December 31, 2022, 2021 and 2020, respectively, did not pay its contractual amounts due under its lease agreement. In April 2022, the lease with the 1.2% Operator was amended to allow the operator to apply its $2.0 million security deposit toward payment of March 2022 rent and to allow for a short-term rent deferral for April 2022 with regular rent payments required to resume in May 2022. The 1.2% Operator paid contractual rent in May 2022, but it failed to pay the full contractual rent for June 2022 on a timely basis. We placed the 1.2% Operator on a cash basis of revenue recognition during the second quarter of 2022 and wrote-off approximately $8.3 million of straight-line rent receivables. During the third and fourth quarters of 2022, the 1.2% Operator made partial contractual rent payments totaling $4.0 million. We are in discussions to sell or release to another operator a portion of the facilities included in the 1.2% Operator’s master lease. 2.0% Operator In June 2022, an operator (the “2.0% Operator”), representing 2.0%, 2.1% and 2.2% of total revenue (excluding the impact of write-offs) for the years ended December 31, 2022, 2021 and 2020, respectively, short-paid the contractual rent amount due under its lease agreement by $0.6 million. In July 2022, we drew the full $5.4 million letter of credit that was held as collateral from the 2.0% Operator and applied $0.6 million of the proceeds to pay the unpaid portion of June 2022 rent. In the third quarter of 2022, the 2.0% Operator continued to short-pay the contractual amount due under its lease agreement. As such, we applied $3.3 million of the remaining proceeds of the letter of credit to pay the unpaid portion of July, August and September 2022 rent. We placed the 2.0% Operator on a cash basis of revenue recognition during the third quarter of 2022 and wrote-off approximately $10.5 million of straight-line rent receivables and lease inducements. In the fourth quarter of 2022, the 2.0% Operator paid $2.2 million in contractual rent and we applied the remaining $1.5 million of collateral against the remaining unpaid rent. As of February 1, 2023, we have transitioned 19 of the 23 facilities previously included in the 2.0% Operator’s master lease to other operators and are in discussions to re-lease the remaining four facilities to another operator. 0.4% Operator In June 2022, we placed an operator (the “0.4% Operator”), representing 0.4%, 0.5% and 0.6% of total revenue (excluding the impact of write-offs) for the years ended December 31, 2022, 2021 and 2020, respectively, on a cash basis of revenue recognition. The change in our evaluation of the collectibility of future rent payments due from the 0.4% Operator was a result of information received from the operator during the second quarter of 2022 regarding substantial doubt as to its ability to continue as a going concern. As a result of placing the 0.4% Operator on a cash basis, we wrote-off approximately $2.1 million of straight-line rent receivables through rental income. For the year ended December 31, 2022, the 0.4% Operator failed to pay four months of rent representing $2.0 million. 0.9% Operator In November and December 2022, an operator that was already on a cash basis of revenue recognition (the “0.9% Operator”), representing 0.9%, 1.0% and 1.0% of total revenue (excluding the impact of write-offs) for the years ended December 31, 2022, 2021 and 2020, respectively, did not pay its contractual amounts due under its lease and loan agreements. Healthcare Homes Limited In December 2022, we agreed to allow Healthcare Homes Limited (“Healthcare Homes”), a U.K. based operator representing 2.9%, 2.4% and 2.3% of total revenue (excluding the impact of write-offs) for the years ended December 31, 2022, 2021 and 2020, respectively, the ability to defer up to £6.7 million of contractual rent from January 2023 through April 2023 with regular payments required to resume in May 2023. The deferred rent balance accrues interest monthly at a rate of 8% per annum and must be fully repaid by December 31, 2024. Healthcare Homes remains current as of December 31, 2022 and is on a straight-line basis of revenue recognition. Other Operators During the year ended December 31, 2022, in addition to the operators specifically discussed above, we allowed four other operators, representing an aggregate 2.7%, 3.2% and 3.6% of total revenue (excluding the impact of write-offs) for the years ended December 31, 2022, 2021 and 2020, respectively, to apply an aggregate of $3.4 million of their security deposits to pay rent to accommodate short term liquidity issues, with regular rent payments required to resume shortly thereafter. These operators also are required to begin replenishing their security deposits in 2023. Additionally, we granted three of these operators short-term deferrals for a portion of their respective rent due during the year ended December 31, 2022. As of December 31, 2022, three of the four operators that were allowed to apply security deposits to rent are current on their respective lease obligations after taking into account rent deferrals and/or the application of security deposits. The one operator that is not current on contractual obligations is on a cash basis of revenue recognition as of December 31, 2022. Lease Inducements For the years ended December 31, 2021 and 2020, we provided fundings of $22.3 million, and $34.1 million, respectively, to our operators subject to operating leases, which were accounted for as lease inducements and will be amortized as a reduction to rental income over the remaining term of the leases. Of the $22.3 million funded in 2021, $20 million was paid to LaVie and $2.3 million was paid to four other existing operators. Of the $34.1 million funded in 2020, $23.9 million was paid to Maplewood for development and start-up related costs and the remaining $10.2 million was paid to three other operators.

Interest income on real estate loans is included within interest income on the Consolidated Statements of Operations and is summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ 2022 ​ 2021 ​ 2020 ​ (in thousands) Mortgage notes – interest income $ 74,233 ​ $ 91,661 ​ $ 89,422 Leasehold mortgages and other real estate loans – interest income ​ 36,089 ​ ​ 31,988 ​ ​ 27,867 Total real estate loans interest income $ 110,322 ​ $ 123,649 ​ $ 117,289 ​ Mortgage Notes due 2030 On June 30, 2022, Ciena Healthcare (“Ciena”) repaid $57.1 million under the $415.0 million amortizing mortgage (the “Ciena Master Mortgage”), $15.1 million under the $44.7 million mortgage and $41.5 million under four additional mortgages. Concurrent with these repayments, we released the mortgage liens on six facilities in exchange for the partial repayment and extended the maturity date of all of the Ciena mortgage notes to June 30, 2030 (with exception of two loans with an aggregate principal balance of $40.4 million with maturity dates in 2023). On September 9, 2022, Ciena repaid $35.3 million under the Ciena Master Mortgage and $9.5 million under three additional mortgages. Concurrently with these partial repayments, we released the mortgage liens on two facilities in exchange for such partial repayments. At December 31, 2022, the $506.3 million of Mortgage Notes with Ciena consisted of the following: ● $415 million Ciena Master Mortgage that matures in 2030 . The Ciena Master Mortgage note bore an initial interest rate of 9.0% per annum which increases by 0.225% per annum. In May 2020, we amended the Ciena Master Mortgage to increase the interest rate by 54 basis points from 10.13% per annum to 10.67% per annum and we sold eight SNFs and one ALF located in Michigan to Ciena for $83.5 million (as discussed below). As of December 31, 2022, the outstanding principal balance of the Ciena Master Mortgage note is $279.0 million and it is secured by 20 facilities. The interest rate on the Ciena Master Mortgage was 11.35% at December 31, 2022. ● Additional borrowings in the form of incremental facility mortgages, construction and/or improvement mortgages with maturities through 2030 (with exception to one construction mortgage with principal of $19.1 million that matures in 2023 ) with initial annual interest rates ranging between 8.5% and 10% and fixed annual escalators of 2% or 2.5% over the prior year’s interest rate, or a fixed increase of 0.225% per annum. As of December 31, 2022, the outstanding principal balance of these mortgage notes which are secured by three facilities is $94.3 million. During the second quarter of 2021, one construction mortgage, included in the mortgage notes described above, with an original maturity date of 2021 was extended to 2029 and converted into a facility mortgage. During the third quarter of 2021, we acquired a facility which was previously subject to a $13.9 million construction mortgage, also included in the notes described above, and subsequently leased the property back to Ciena. ● $44.7 million mortgage note related to five SNFs located in Michigan. The mortgage note matures on June 30, 2030 and bore an initial annual interest rate of 9.5% which increases each year by 0.225% . The interest rate on the mortgage note was 10.4% at December 31, 2022. During the second quarter of 2022, we released the mortgage lien on one facility under this mortgage loan in exchange for a $15.1 million repayment (as discussed above). As of December 31, 2022, the outstanding principal balance of this mortgage note is $28.6 million and it is secured by four SNFs. Additionally, the Company committed to fund an additional $9.6 million to Ciena if certain performance metrics are achieved by the portfolio. ● $83.5 million mortgage note related to eight SNFs and one ALF located in Michigan. These nine facilities were formerly leased to Ciena and were sold to Ciena by issuance of a first mortgage on May 1, 2020. The mortgage note matures on June 30, 2030 and bore an initial annual interest rate of 10.31% which increases each year by 2% . The interest rate on the mortgage note was 10.73% at December 31, 2022. As of December 31, 2022, the outstanding principal balance of this mortgage note is $83.1 million. ● $21.3 million mortgage note related to one SNF located in Ohio. The mortgage note had an original maturity date of March 31, 2022 and bore an initial annual interest rate of 9.5% . During the year ended December 31, 2022, we amended the mortgage note to extend the maturity date to December 31, 2023 and to increase the interest rate to 9.74% beginning April 1, 2022 and to 9.98% beginning April 1, 2023. As of December 31, 2022, the outstanding principal balance of this mortgage note is $21.3 million. The mortgage notes with Ciena are cross-defaulted and cross-collateralized with our existing master lease and other non-real estate loans with Ciena. Mortgage Note due 2031 On January 17, 2014, we entered into a $112.5 million first mortgage loan with Guardian. The loan was originally secured by seven SNFs and two ALFs located in Pennsylvania and Ohio. The mortgage is cross-defaulted and cross-collateralized with our existing master lease with the operator. In March 2018, we extended the maturity date to January 31, 2027 and provided an option to extend the maturity for a five year period through January 31, 2032 and a second option to extend the maturity through September 30, 2034. In the third quarter of 2021, we reduced the risk rating on the mortgage loan from a 4 to a 5, primarily due to the increased likelihood of a restructuring that would result in the modification of the mortgage loan terms. As discussed in Note 5 – Contractual Receivables and Other Receivables and Lease Inducements, Guardian failed to pay contractual rent and interest to us during the fourth quarter of 2021. The mortgage loan was placed on non-accrual status for interest recognition in October 2021 and is being accounted for under the cost recovery method. On December 30, 2021, we acquired two facilities, previously subject to the Guardian mortgage loan, in consideration for a reduction of $8.7 million in the mortgage principal and added the facilities to the master lease agreement. Following Guardian’s non-payment of rent and interest during the fourth quarter of 2021 and further negotiations with Guardian in the fourth quarter, we elected to further reduce the risk rating on the loan from a 5 to a 6 in the fourth quarter of 2021 and to evaluate the risk of loss on the loan on an individual basis. As the fair value of the 7 properties that collateralized the mortgage loan were estimated to be less than the remaining principal as of December 31, 2021 of $103.8 million, we reserved an additional $38.2 million through provision for credit losses in the fourth quarter of 2021. The total reserve as of December 31, 2021, related to the mortgage loan was $47.1 million and reduced the loan carrying value to the estimated fair value of the collateral of $56.7 million as of December 31, 2021. We also fully reserved approximately $1.0 million of contractual interest receivable related to the mortgage loan with Guardian in the fourth quarter of 2021. Guardian continued to not pay contractual rent and interest due under its lease and mortgage loan agreements during the first quarter of 2022. On February 15, 2022, Guardian completed the sale of three facilities subject to the Guardian mortgage loan with Omega. Concurrent with the sale, Omega agreed to release the mortgage liens on these facilities in exchange for a partial paydown of $21.7 million. In connection with the partial paydown, we recorded a $5.1 million recovery for credit losses in the first quarter of 2022 related to the Guardian mortgage loan. In the second quarter of 2022, we agreed to a formal restructuring agreement and amendments to the master lease and mortgage loan with Guardian, which among other adjustments, extended the loan maturity and allowed for the deferral of certain contractual interest as discussed in Note 5 – Contractual Receivables and Other Receivables and Lease Inducements. These amendments were treated as a loan modification. Following the execution of the restructuring agreement, Guardian resumed paying contractual rent and interest during the second quarter of 2022 and continued such payments in the third and fourth quarters of 2022, in accordance with the restructuring terms. In the third and fourth quarters of 2022, we reserved an additional $0.3 million, in aggregate, through provision for credit losses due to a decrease in the estimated fair value of the four facilities that are collateral under the mortgage. As of December 31, 2022, the amortized cost basis of the Guardian mortgage loan is $76.0 million, which represents 6.6% of the total amortized cost basis of all real estate loan receivables. The total reserve as of December 31, 2022 related to the mortgage loan was $40.8 million and reduced the loan carrying value to the estimated fair value of the collateral of $35.2 million as of December 31, 2022. As of December 31, 2022, the mortgage loan is secured by three SNFs and one ALF located in Pennsylvania. During the year ended December 31, 2022, we received $6.0 million of interest payments that were applied directly against the principal balance outstanding using the cost recovery method. Other mortgage notes outstanding As of December 31, 2022, our other mortgage notes outstanding represents 4 mortgage loans to 4 operators with liens on 11 facilities. Included below are new mortgage loans within this bucket that were entered into during the years ended December 31, 2022, and 2021. Mortgage Note due 2032 ; interest at 10.50% On July 1, 2021, we financed six SNFs in Ohio and amended an existing $6.4 million mortgage, inclusive of two Ohio SNFs, to include the six facilities in a consolidated $72.4 million mortgage for eight Ohio facilities bearing interest at an initial rate of 10.5% per annum. In conjunction with this transaction, we also acquired three Maryland facilities that were previously subject to a mortgage issued by Omega bearing interest at 13.75% per annum with a principal balance of $36.0 million that was included in other mortgage notes outstanding. The purchase price for these three facilities was equal to the remaining mortgage principal amount, and the three acquired Maryland facilities were subsequently leased back to the seller for a term expiring on December 31, 2032, assuming Omega exercises the options under the agreement. The base rent in the initial year is approximately $5.0 million and includes annual escalators of 2.5%. As of December 31, 2022, the outstanding principal balance of this mortgage note is $72.4 million. Mortgage Note due 2025 ; interest at 7.85% In connection with the MedEquities Merger on May 17, 2019, the Company acquired a first mortgage lien issued to Lakeway Realty, L.L.C, an unconsolidated joint venture discussed in Note 11 – Investments in Joint Ventures, in the original principal amount of approximately $73.0 million bearing interest at 8% per annum based on a 25-year amortization schedule and maturing on March 20, 2025. We determined the acquisition date fair value of the acquired mortgage was $69.1 million. As of December 31, 2022 and 2021, this mortgage has a carrying value of $63.8 million and $65.5 million, respectively. Other real estate loan due 2030 On July 31, 2020, we entered into a $220.5 million secured revolving credit facility with Maplewood as a part of an overall restructuring with this operator. $132.1 million of the facility was drawn at closing which was used to repay our prior secured revolving credit facilities with aggregate capacity of $65.0 million with Maplewood, as well as other lease obligations owed to us, of which approximately $55.4 million was scheduled to be repaid at termination of the master lease. Loan proceeds under the new credit facility may also be used to fund Maplewood’s working capital needs. Advances made under this facility bear interest at a fixed rate of 7% per annum and the facility matures on June 30, 2030. On June 22, 2022, we amended the secured revolving credit facility with Maplewood to increase the maximum commitment under the facility from $220.5 million to $250.5 million. Maplewood was determined to be a VIE when this loan was originated in 2020. Our balances and risk of loss associated with Maplewood are included within our disclosures in Note 10 – Variable Interest Entities. As discussed in Note 5 – Contractual Receivables and Other Receivables and Lease Inducements, we began negotiations to restructure and amend Maplewood’s lease and loan agreements during the fourth quarter of 2022. As a result of the anticipated restructuring, we placed the Maplewood revolving credit facility on non-accrual status for interest recognition during the fourth quarter of 2022 due to the anticipated restructuring of its lease and loan agreement. As of December 31, 2022, $250.5 million remains outstanding on this credit facility to Maplewood. As discussed in Note 5 – Contractual Receivables and Other Receivables and Lease Inducements, in the first quarter of 2023, Omega entered into a restructuring agreement and a loan amendment that modified the senior revolving credit facility. As part of the restructuring agreement and loan amendment, Omega agreed to extend the maturity date to June 2035, increase the capacity of the senior revolving credit facility from $250.5 million to $320.0 million, including PIK interest applied to the principal, and to convert the 7% cash interest due on the senior revolving credit facility to all PIK interest in 2023, 1% cash interest and 6% PIK interest in 2024, 4% cash interest and 3% PIK interest in 2025 and through the maturity date. Other real estate loans due 2024 Our other investment notes due in 2024 consists of two secured term loans with Genesis with initial borrowings of $48.0 million and $16.0 million at issuance. The $48.0 million term loan was issued in July 2016 (the “2016 Term Loan”), with subsequent amendments in 2018, 2019 and 2021, and currently bears interest at a fixed rate of 14% per annum, of which 9% per annum is paid-in-kind. The 2016 Term Loan was initially scheduled to mature on July 29, 2020, but through the amendments noted above, the maturity date of this loan was extended to January 1, 2024. The $16.0 million secured term loan was issued on March 6, 2018 (the “2018 Term Loan”), and amended in 2021, and bears interest at a fixed rate of 10% per annum, of which 5% per annum is paid-in-kind. The 2018 Term Loan was initially scheduled to mature on July 29, 2020, but through the amendments noted above was extended to January 1, 2024. Both the 2016 and 2018 Term Loans are on an accrual status as of December 31, 2022. Both the 2016 and 2018 Term Loans are secured by a first priority lien on and security interest in certain collateral of Genesis. As of December 31, 2022, there was approximately $78.1 million and $20.3 million outstanding on the 2016 and 2018 Term Loans, respectively. Other real estate loans due 2022 - 2025 On June 28, 2022, we entered into a $35.6 million mezzanine loan with an existing operator related to new operations undertaken by the operator. The loan bears interest at a fixed rate of 12% per annum and matures on June 30, 2025. The loan also requires quarterly principal payments of $1.0 million commencing on January 1, 2023 and additional payments contingent on the operator’s achievement of certain metrics. The loan is secured by a leasehold mortgage and a pledge of the operator’s equity interest in a joint venture. Other real estate loan due 2024 Our other investment note due in 2024 consisted of a $60.0 million mezzanine loan, with an operator, that was acquired and financed in 2016 and subsequently amended and refinanced in May 2018. The loan was amended again in 2022. As amended, the mezzanine loan bore interest at a fixed interest rate of 12% per annum and contractually matured on May 31, 2024. During the third quarter of 2022, this loan was fully repaid Other real estate loans outstanding Preferred Equity Investment in Joint Venture - $20 million On June 2, 2022, we made a $20.0 million preferred equity investment, which is treated as a loan for accounting purposes, in a new real estate joint venture that was formed to acquire an acute care hospital in New York. Omega’s preferred equity investment bears a 12% return per annum and must be mandatorily redeemed by the joint venture at the earlier of December 2027 or the occurrence of certain significant events within the joint venture. We have determined that the joint venture is a VIE, but we are not the primary beneficiary as we do not have the power to direct the activities that most significantly impact the joint venture’s economic performance. As such, this $20.0 million preferred equity investment is included in the unconsolidated VIE table presented in Note 10 – Variable Interest Entities.

NON-REAL ESTATE LOANS RECEIVABLE [Abstract]
NON-REAL ESTATE LOANS RECEIVABLE	NOTE 8 – NON-REAL ESTATE LOANS RECEIVABLE Our non-real estate loans consist of fixed and variable rate loans to operators and/or principals. These loans may be either unsecured or secured by the collateral of the borrower, which may include the working capital of the borrower. As of December 31, 2022, we had 29 loans with 15 different borrowers. ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ December 31, ​ ​ 2022 2021 ​ ​ ​ (in thousands) ​ Notes due 2024-2025; interest at 8.12% (1) ​ $ 55,791 $ 55,791 ​ Notes due 2022-2028; interest at 10.44% (1)(2) ​ ​ 55,981 ​ ​ 22,142 ​ Notes due 2036; interest at 8.13% (1) ​ ​ 32,539 ​ ​ 2,690 ​ Note due 2027; interest at 12.00% ​ ​ 39,653 ​ ​ — ​ Note due 2024; interest at 7.50% ​ ​ 47,999 ​ ​ 15,000 ​ Other notes outstanding (3) ​ 77,186 ​ 88,982 ​ Non-real estate loans receivable – gross ​ ​ 309,149 ​ ​ 184,605 ​ Allowance for credit losses on other investments ​ ​ (83,868) ​ ​ (60,421) ​ Total non-real estate loans receivable – net ​ $ 225,281 ​ $ 124,184 ​ (1) Approximate weighted average interest rate as of December 31, 2022.

(3) Other notes outstanding have a weighted average interest rate of 7.18% as of December 31, 2022 with maturity dates ranging from 2022 through 2028 (with $10.8 million maturing in 2023 ). We have two loans within other notes outstanding with aggregate principal of $9.8 million that were to mature in 2022 , but remain outstanding as of December 31, 2022. We are in negotiations to extend a $4.4 million loan to 2024 and we have fully reserved the other $5.4 million loan. ​ For the years ended December 31, 2022, 2021 and 2020, non-real estate loans generated interest income of $13.6 million, $12.7 million and $17.0 million, respectively. Interest income on non-real estate loans is included within interest income on the Consolidated Statements of Operations. Notes due 2024 - 2025 Notes due in 2024-2025 consist of a $32 million secured term loan (the “Agemo Term Loan”) and a $25.0 million secured working capital loan (the “Agemo WC Loan”) with Agemo. The Agemo Term Loan was acquired in 2016 and bears interest at 9% per annum. The Agemo Term Loan matures on December 31, 2024 and is secured by a security interest in certain collateral of Agemo. The Agemo WC Loan was issued on May 7, 2018 and bears interest at 7% per annum. The Agemo WC Loan matures on April 30, 2025 and is primarily secured by a collateral package that includes a second lien on the accounts receivable of Agemo. The proceeds of the Agemo WC Loan were used to pay operating expenses, settlement payments, fees, taxes and other costs approved by the Company. During the third quarter of 2020, we evaluated both loans for impairment upon receiving information from Agemo regarding substantial doubt of its ability to continue as a going concern. Based on our evaluation, we recorded a provision for credit loss of $22.7 million in the third quarter of 2020 to reduce the carrying value of the loans to the fair value of the underlying collateral. We also fully reserved approximately $3.8 million of contractual interest receivable related to the Agemo Term Loan in the third quarter of 2020 (see Note 9 – Allowance for Credit Losses). As discussed in Note 5 – Contractual Receivables and Other Receivables and Lease Inducements, Agemo failed to pay contractual rent and interest to us from August 2021 through October 2021 and in December 2021. In the third quarter of 2021, we recorded an additional provision for credit loss of $16.7 million related to these loans as a result of a reduction in the fair value of the underlying collateral assets. The reduction in fair value of the collateral assets was primarily driven by the application of Agemo’s $9.3 million letter of credit that supported the value of the Agemo Term Loan to Omega’s uncollected receivables and a reduction in Agemo’s working capital accessible to Omega as collateral, after considering other liens on the assets. Additionally, the loan has been placed on non-accrual status and we will use the cost recovery method and will apply any interest and fees received directly against the principal of the loan. During the year ended December 31, 2021, we received $1.2 million of interest payments which was applied against the principal. Agemo continued to not pay contractual rent and interest due under its lease and loan agreements throughout 2022. During the year ended December 31, 2022, we recorded additional provisions for credit losses of $10.8 million related to the Agemo WC Loan because of reductions in the fair value of the underlying collateral assets supporting the current carrying values. At December 31, 2022, the total carrying value of our loans outstanding with Agemo, net of allowances for credit losses, is approximately $5.9 million. As discussed in Note 5 – Contractual Receivables and Other Receivables and Lease Inducements, in the first quarter of 2023, Omega entered into a restructuring agreement and a replacement loan agreement that modified the existing Agemo loans. Under the restructuring agreement, previously written off contractual unpaid interest related to the Agemo WC Loan and the Agemo Term Loan was forgiven. The outstanding principal of the Agemo Term Loan was rolled into a $32.0 million loan (“Agemo Replacement Loan A”). The outstanding principal of the Agemo WC Loan and the aggregate rent deferred and outstanding under the Agemo lease agreement will be combined into a $50.2 million loan (“Agemo Replacement Loan B” and with Agemo Replacement Loan A, the “Agemo Replacement Loans”). The Agemo Replacement Loans bear interest at 5.71% per annum and mature on December 31, 2036. No interest payments will accrue or are required to be paid until March 1, 2023, contingent upon Agemo’s compliance with certain conditions of the restructuring agreement. After three years, Agemo is required to make principal payments on the Agemo Replacement Loans dependent on certain cash flow metrics. Notes due 2022 - 2028 Notes due 2022-2028 consists of eight loans with the same operator that are primarily short-term revolving lines of credit that are collateralized by the accounts receivable of certain operations of the operator. The most significant of the outstanding loans is a short-term $90.0 million revolving line of credit that we entered into on June 28, 2022 in connection with the $35.6 million mezzanine loan discussed in Note 7 – Real Estate Loans Receivable above. The loan proceeds were used by this operator to finance working capital requirements of new operations in a new state to the operator. The line of credit consists of two Notes due 2036 On September 1, 2021, we entered into an $8.3 million term loan with LaVie to be funded through monthly advances in the amount of $0.7 million from September 2021 through August 2022. This term loan bears interest at a fixed rate of 7% per annum (which may be paid-in-kind for the first year of the loan), matures on March 31, 2031 and requires monthly principal payments of $0.1 million commencing September 1, 2022. The loan is secured by a guarantee from LaVie’s parent entities. On March 25, 2022, we entered into a $25.0 million term loan with LaVie that bears interest at a fixed rate of 8.5% per annum and matures on March 31, 2032. This term loan requires quarterly principal payments of $1.3 million commencing January 1, 2028 and is secured by a second priority lien on the operator’s accounts receivable. During the fourth quarter of 2022, we amended these loans with LaVie to, among other terms, extend the loan maturities to November 30, 2036 to align with the lease term, and starting in January 2023, reduce the interest rates to 2%, remove the requirement to make any principal payments until the maturity dates and to convert from monthly cash interest payments to interest paid-in-kind. These amendments were treated as loan modifications. In the fourth quarter of 2022, we reduced the risk rating on these loans from a 5 to a 6, primarily due to the modifications of the loan terms. Given the modifications, we evaluated the risk of loss on these loans on an individual basis based on the fair value of the collateral. Based on our evaluation of the collateral, during the fourth quarter of 2022, we recognized provisions for credit losses of $7.5 million related to the $8.3 million term loan (to fully reserve the loan balance) and $15.8 million related to the $25.0 million term loan. Following the sale of 11 facilities in the fourth quarter of 2022, discussed in Note 4 – Assets Held for Sale, Dispositions and Impairments, the remaining accounts receivable outstanding that collateralize the $25.0 million term loan was insufficient to support the current outstanding balance, and as a result, we recorded the additional reserves to reduce the carrying value of the $25.0 million loan to the fair value of the collateral. Additionally, the loans were placed on non-accrual status and we will use the cost recovery method and will apply any interest and fees received directly against the principal of the loans. During the year ended December 31, 2022, we applied $0.4 million of interest payments received to the $25.0 million term loan principal balance outstanding and $0.1 million of interest payments received to the $8.3 million term loan principal balance outstanding. As of December 31, 2022, the amortized cost basis of these loans was $32.5 million, which represents 10.5% of the total amortized cost basis of all non-real estate loan receivables. The total reserve as of December 31, 2022 related to the LaVie loans was $25.0 million. Note due 2027 On September 1, 2022, we entered into a $40.0 million mezzanine loan with a new operator. The loan bears interest at a fixed rate of 12% per annum and matures on September 14, 2027. The loan also requires semi-annual principal payments of $1.7 million in January and July, commencing on January 1, 2023, and additional payments contingent on the occurrence of certain conditions. The loan is secured by an equity interest in subsidiaries of the operator. In February 2023, this loan was repaid. Note due 2024 On July 8, 2019, the Company entered into a $15 million unsecured revolving credit facility agreement with a principal of an operator that bears interest at a fixed rate of 7.5% per annum and originally matured on July 8, 2022. During 2022, this revolving credit facility was amended multiple times to increase the maximum principal to $48 million, extend the maturity date to December 31, 2024 and require monthly principal payments of $0.5 million beginning in July 2022, which increase to $1.0 million in January 2023, to $1.5 million in August 2023 and to $2.5 million in December 2023. No principal payment amounts were required for the months of November and December 2022. Other notes outstanding As of December 31, 2022, our other notes outstanding represents 15 loans to operators that primarily consists of term loans and working capital loans or revolving credit facilities. Many of these loans are not individually significant and the use of proceeds of these loans can vary. Included below are the significant new loans entered into during the years ended December 31, 2022, 2021 and 2020 and significant updates to any existing loans. Working Capital Loan – $20 million In November 2021, we entered into a $20.0 million working capital loan (the “$20.0 million WC loan”) with an operator that managed, on an interim basis for a 4-month period, the operations of 23 facilities formerly leased to Gulf Coast. The $20.0 million WC loan bears interest at 3% per annum. The maturity date of the $20.0 million WC loan was the earlier of (i) December 31, 2022, (ii) the date of the termination of one or more of the MOTAs, or (iii) the date that New Manager requests that the loan be terminated. Advances under the working capital loan are not required to be repaid until maturity. The $20.0 million WC loan is secured by the accounts receivables of these facilities during the interim period of operation. During the year ended December 31, 2022, we recognized provisions for credit losses of $5.2 million related to the $20.0 million WC loan, which resulted in the loan being fully reserved. Following the sale of 22 facilities, discussed in Note 4 – Assets Held for Sale, Dispositions and Impairments, the remaining accounts receivable outstanding that collateralize the loan was insufficient to support the current outstanding balance, and as a result, we recorded the additional reserves to reduce the carrying value of the loan to the fair value of the collateral. The $20.0 million WC Loan was placed on non-accrual status during the third quarter of 2022 and is being accounted for under the cost recovery method. As of December 31, 2022, the outstanding principal under this loan was $5.4 million. Gulf Coast – DIP Facility During the year ended December 31, 2022, we recorded an additional net provision for credit losses of $0.2 million related to the DIP Facility, which reflects the full reserve of additional advances of $2.2 million made under the facility during 2022 and a $2.0 million recovery for interest and fee payments received during 2022 that were applied against the outstanding principal. The DIP facility matured on August 15, 2022, which resulted in a write-off of the loan and reserve balances. Revolving Credit Facility – $25 million As discussed in Note 5 – Contractual Receivables and Other Receivables and Lease Inducements, from January through March 2022, the 3.7% Operator paid contractual interest under the credit facility but failed to pay contractual rent due under its lease agreement. In March 2022, the lease with the 3.7% Operator was amended to allow for a short-term rent deferral for January through March 2022. The 3.7% Operator paid the contractual amount due under its lease and loan agreements from April 2022 through December 2022. Promissory Notes – $20 million In the fourth quarter of 2022, the Company entered into three unsecured loans with a principal of an operator with principal amounts of $17.0 million, $2.5 million and $0.5 million. The loans bear interest at 9% and mature on September 30, 2027. All three loans require quarterly principal payments commencing on January 3, 2023. Second Spring Healthcare Investments On April 17, 2020, we provided a $17.6 million unsecured loan to a subsidiary of Second Spring Healthcare Investments (an entity in which we have an approximate 15% ownership interest, see Note 11 – Investments in Joint Ventures) bearing interest at the greater of the prime interest rate or 3-month LIBOR plus 2.75% per annum which was due on demand. This loan was repaid in 2021.

We write-off interest receivable to provision for credit losses in the period we determine the interest is no longer considered collectible. For the years ended December 31, 2021 and 2020, we wrote-off interest receivables of $1.0 million (related to the Guardian mortgage loan, see Note 7 – Real Estate Loans Receivable) and $3.8 million (related to the Agemo Term Loan, see Note 8 – Non-real Estate Loans Receivable) through the provision for credit losses. This write-off is not reflected in the roll forward of the allowance for credit losses above.

The fair value of the accounts receivable available to Omega was $5.9 million and $29.2 million as of December 31, 2022 and December 31, 2021, respectively. In determining our maximum exposure to loss from these VIEs, we considered the underlying carrying value of the real estate subject to leases with these operators and other collateral, if any, supporting our other investments, which may include accounts receivable, security deposits, letters of credit or personal guarantees, if any, as well as other liabilities recognized with respect to these operators.

(5) Borrowing is the debt of the consolidated joint venture discussed in Note 10 – Variable Interest Entities which was formed in the first quarter of 2022. The borrowing is secured by two ALFs, which are owned by the joint venture. (6) Guaranteed by Omega OP. (7) As of December 31, 2022, borrowings under Omega’s $1.45 billion senior unsecured multicurrency revolving credit facility consisted of £16.0 million British Pounds Sterling (“GBP”). The applicable interest rate on the US Dollar tranche and on the GBP borrowings under the alternative currency tranche of the credit facility were 5.58% and 4.75% as of December 31, 2022, respectively. (8) In March 2021, we used a portion of the proceeds from the 2033 Senior Notes offering to fund the tender offer to redeem $350 million of the 4.375% Senior Notes due 2023 . In connection with this transaction, we recorded approximately $30.6 million in related fees, premiums, and expenses for the year ended December 31, 2021, which were recorded as Loss on debt extinguishment in our Consolidated Statement of Operations. (9) In March 2021, we used the proceeds from this offering to pay down outstanding borrowings on the 2017 Revolving Credit Facility, repay the Sterling term loan, and fund the tender offer to purchase $350 million of the 4.375% Senior Notes due 2023 and the payment of accrued interest and related fees, premiums and expenses. (10) Omega OP is the obligor on this borrowing. (11) The interest rate swaps, that were cash flow hedges of Omega OP’s $50.0 million senior unsecured term loan facility’s (the “OP term loan”) interest payments and that effectively fixed the interest rate at 3.29% , matured on February 10, 2022 . (12) All borrowings are direct borrowings of Parent unless otherwise noted. (13) Certain of our other secured and unsecured borrowings are subject to customary affirmative and negative covenants, including financial covenants. As of December 31, 2022 and December 31, 2021, we were in compliance with all applicable covenants for our borrowings. Secured Borrowings HUD Mortgage Debt ​ On October 31, 2019, we assumed approximately $389 million in mortgage loans guaranteed by HUD. The HUD loans have maturity dates between 2046 and 2052 with fixed interest rates ranging from 2.82% per annum to 3.24% per annum. The HUD loans may be prepaid subject to an initial penalty of 10% of the remaining principal balances in the first year and the prepayment penalty decreases each subsequent year by 1% until no penalty is required. On August 26, 2020, we paid approximately $13.7 million to retire two mortgage loans guaranteed by HUD that were assumed in 2019 and had an average interest rate of 3.08% per annum with maturities in 2051 and 2052. The payoff included a $0.9 million prepayment fee which is included in loss on debt extinguishment on our Consolidated Statements of Operations. On August 31, 2022, we paid approximately $7.9 million to retire one mortgage loan guaranteed by HUD that was assumed in 2019 and had a fixed interest rate of 2.92% per annum with a maturity date in 2051. The payoff included a $0.4 million prepayment fee which is included in loss on debt extinguishment on our Consolidated Statements of Operations. Unsecured Borrowings Revolving Credit Facility On April 30, 2021, Omega entered into a credit agreement (the “2021 Omega Credit Agreement”) providing us with a new $1.45 billion senior unsecured multicurrency revolving credit facility (the “Revolving Credit Facility”), replacing our previous $1.25 billion senior unsecured 2017 multicurrency revolving credit facility (the “2017 Revolving Credit Facility”). The 2021 Omega Credit Agreement contains an accordion feature permitting us, subject to compliance with customary conditions, to increase the maximum aggregate commitments thereunder to $2.5 billion, by requesting an increase in the aggregate commitments under the Revolving Credit Facility or by adding term loan tranches. The Revolving Credit Facility bears interest at LIBOR (or in the case of loans denominated in GBP, the Sterling overnight index average reference rate plus an adjustment of 0.1193% per annum, and in the case of loans denominated in Euros, the Euro interbank offered rate, or EURIBOR) plus an applicable percentage (with a range of 95 to 185 basis points) based on our credit ratings. The Revolving Credit Facility matures on April 30, 2025, subject to Omega’s option to extend such maturity date for two six-month periods. The Revolving Credit Facility may be drawn in Euros, GBP, Canadian Dollars (collectively, “Alternative Currencies”) or USD, with a $1.15 billion tranche available in USD and a $300 million tranche available in Alternative Currencies. For purposes of the Revolving Credit Facility, references to LIBOR include the Canadian dealer offered rates for amounts offered in Canadian Dollars and any other Alternative Currency rate approved in accordance with the terms of the 2021 Omega Credit Agreement for amounts offered in any other non-LIBOR quoted currency, as applicable. The Revolving Credit Facility includes customary LIBOR replacement language, including, but not limited to, the use of rates for U.S. dollar-denominated borrowings based on the secured overnight financing rate (“SOFR”) recommended by the Alternative Reference Rates Committee, a steering committee comprised of U.S. financial market participants, as a replacement rate for LIBOR. SOFR is a broad measure of the cost of borrowing cash in the overnight U.S. Treasury repo market, and is administered by the Federal Reserve Bank of New York. We incurred $12.9 million of deferred costs in connection with the 2021 Omega Credit Agreement. OP Term Loan On April 30, 2021, Omega OP entered into a credit agreement (the “2021 Omega OP Credit Agreement”) providing it with a new $50 million senior unsecured term loan facility (the “OP Term Loan”). The OP Term Loan replaces the $50 million senior unsecured term loan obtained in 2017 (the “2017 OP Term Loan”) and the related credit agreement. The OP Term Loan bears interest at LIBOR plus an applicable percentage (with a range of 85 to 185 basis points) based on our credit ratings. The OP Term Loan includes customary LIBOR replacement language, including, but not limited to, the use of rates based on SOFR. The OP Term Loan matures on April 30, 2025, subject to Omega OP’s option to extend such maturity date for two, six-month periods. We incurred $0.4 million of deferred costs in connection with the 2021 Omega OP Credit Agreement. 2017 Omega Credit Facilities On May 25, 2017, Omega entered into a credit agreement (the “2017 Omega Credit Agreement”) for a new $1.8 billion senior unsecured revolving and term loan credit facility, consisting of a $1.25 billion senior unsecured multicurrency revolving credit facility (the “2017 Revolving Credit Facility”), a $425 million senior unsecured U.S. Dollar term loan facility (the “U.S. Term Loan”), and a £100 million senior unsecured British Pound Sterling term loan facility (the “Sterling Term Loan” and, together with the 2017 Revolving Credit Facility and the U.S. Term Loan Facility, collectively, the “2017 Omega Credit Facilities”). The 2017 Revolving Credit Facility bore interest at LIBOR plus an applicable percentage (with a range of 100 to 195 basis points) based on our ratings from Standard & Poor’s, Moody’s and/or Fitch Ratings. The U.S. Term Loan Facility and the Sterling Term Loan Facility bore interest at LIBOR plus an applicable percentage (with a range of 90 to 190 basis points) based on our ratings from Standard & Poor’s, Moody’s and/or Fitch Ratings. In 2020, we repaid the outstanding balance on our U.S. Term Loan and wrote-off $0.8 million of unamortized deferred costs to loss on debt extinguishment on our Consolidated Statements of Operations. In 2021, we repaid the outstanding balance on our 2017 Revolving Credit Facility and Sterling Term Loan using a portion of the proceeds from the 2033 Senior Notes offering and wrote-off $0.2 million of unamortized deferred costs relating to the Sterling Term Loan to loss on debt extinguishment on our Consolidated Statements of Operations. In April 2021, the 2017 Revolving Credit Facility was replaced by the Revolving Credit Facility. 2017 OP Term Loan On May 25, 2017, Omega OP entered into a credit agreement (the “2017 Omega OP Credit Agreement”) providing it with a new $100 million senior unsecured term loan facility (the “2017 OP Term Loan”). The 2017 OP Term Loan bore interest at LIBOR plus an applicable percentage (with a range of 90 to 190 basis points) based on our ratings from Standard & Poor’s, Moody’s and/or Fitch Ratings. In April 2021, the 2017 OP Term loan was replaced by the OP Term Loan. Amended 2015 Term Loan Facility On May 25, 2017, Omega entered into an amended and restated credit agreement (the “Amended 2015 Credit Agreement”), which amended and restated our previous $250 million senior unsecured term loan facility (the “Amended 2015 Term Loan Facility”). The Amended 2015 Term Loan Facility bore interest at LIBOR plus an applicable percentage (with a range of 140 to 235 basis points) based on our ratings from Standard & Poor’s, Moody’s and/or Fitch Ratings. We repaid the Amended 2015 Term Loan Facility in October 2020 with proceeds from the senior notes issuance and wrote-off $0.7 million of unamortized deferred costs to loss on debt extinguishment on our Consolidated Statements of Operations. Subordinated Debt In connection with a 2010 acquisition, we assumed five separate $4.0 million subordinated notes bearing interest at 9% per annum that mature on December 21, 2021. Interest on these notes is due quarterly with the principal balance due at maturity. As discussed in Note 5 – Contractual Receivables and Other Receivables and Lease Inducements, to the extent that the operator of the facilities (Gulf Coast) failed to pay rent when due to us under our existing master lease, we had the right to offset the amounts owed to us against the amounts we owe to the lender under the notes. As of December 31, 2021, we offset $1.3 million of accrued interest and $20.0 million of principal under the Subordinated Debt against the uncollected receivables of Gulf Coast. Following the application of these offsets, Omega believes it has no further obligations under the Subordinated Debt. See Note 20 – Commitments and Contingencies for additional discussion regarding an ongoing lawsuit related to the Subordinated Debt. General Parent and Omega OP, on a combined basis, have no material assets, liabilities or operations other than financing activities (including borrowings under the senior unsecured revolving and term loan credit facility, OP term loan and the outstanding senior notes) and their investments in non-guarantor subsidiaries. Substantially all of our assets are held by non-guarantor subsidiaries. The required principal payments, excluding the premium or discount and deferred financing costs on our secured and unsecured borrowings, for each of the five years following December 31, 2022 and the aggregate due thereafter are set forth below: ​ ​ ​ ​ ​ ​ (in thousands) 2023 $ 359,898 2024 ​ 427,723 2025 ​ 477,462 2026 ​ 608,466 2027 ​ 708,725 Thereafter ​ 2,753,591 Total ​ $ 5,335,865 ​

DERIVATIVES AND HEDGING [Abstract]
DERIVATIVES AND HEDGING	NOTE 15 – DERIVATIVES AND HEDGING Cash Flow Hedges of Interest Rate Risk We enter into interest rate swaps in order to maintain a capital structure containing targeted amounts of fixed and floating-rate debt and manage interest rate risk. Interest rate swaps designated as cash flow hedges involve the receipt of variable amounts from a counterparty in exchange for our fixed-rate payments. These interest rate swap agreements are used to hedge the variable cash flows associated with variable-rate debt. As a result of exposure to interest rate movements associated with the Amended 2015 Term Loan Facility, on December 16, 2015, we entered into various forward-starting interest rate swap arrangements, which effectively converted $250 million of our variable-rate debt based on one-month LIBOR to an aggregate fixed rate of approximately 3.80% effective December 30, 2016. The effective fixed rate achieved by the combination of the Amended 2015 Term Loan Facility and the interest rate swaps could fluctuate up by 55 basis points or down by 40 basis points based on future changes to our credit ratings. Each of these swaps had a scheduled maturity date of December 15, 2022. In October 2020, we terminated these $250.0 million of notional value interest rate swaps in connection with the repayment of the Amended 2015 Term Loan Facility and paid our swap counterparties $10.3 million which is recorded in loss on debt extinguishment on our Consolidated Statements of Operations. On March 27, 2020, we entered into five forward starting swaps totaling $400 million that are indexed to 3-month LIBOR. We designated the forward starting swaps as cash flow hedges of interest rate risk associated with interest payments on a forecasted issuance of fixed rate long-term debt, initially expected to occur within the next five years. The swaps are effective on August 1, 2023 and expire on August 1, 2033 and were issued at a weighted average fixed rate of approximately 0.8675%. In March 2021, in conjunction with the issuance of $700 million aggregate principal amount of our 3.25% Senior Notes due 2033, we discontinued hedge accounting for these five forward starting swaps. Simultaneously, we re-designated these swaps in new cash flow hedging relationships of interest rate risk associated with interest payments on another forecasted issuance of long-term debt. We are hedging our exposure to the variability in future cash flows for forecasted transactions over a maximum period of 46 months (excluding forecasted transactions related to the payment of variable interest on existing financial instruments). In addition to the forward swaps discussed above, we also assumed various interest rate swap contracts in connection with the MedEquities Merger on May 17, 2019. We designated the interest rate swap contracts as cash flow hedges of interest rate risk associated with the 2017 Omega OP Credit Agreement. The assumed interest rate swap contracts effectively converted $75 million of our 2017 Omega OP Credit Agreement to an aggregate fixed rate of approximately 3.29% through February 10, 2022. The effective fixed rate achieved by the combination of the 2017 Omega OP Credit Agreement and the interest rate swaps could fluctuate up by 55 basis points or down by 45 basis points based on future changes to our credit ratings. In October 2020, we terminated $25.0 million of notional value interest rate swaps in connection with the partial repayment and paid our swap counterparty $0.6 million which is recorded in loss on debt extinguishment on our Consolidated Statements of Operations. On February 10, 2022, the two remaining interest rate swaps with aggregate notional amounts of $50.0 million matured. These interest rate swap contracts were designated as hedges against our exposure to changes in interest payment cash flow fluctuations in the variable interest rates on the OP Term Loan. The OP Term Loan is unhedged for the period after February 10, 2022 through its maturity on April 30, 2025. Foreign Currency Forward Contracts and Debt Designated as Net Investment Hedges We use debt denominated in GBP and foreign currency forward contracts to hedge a portion of our net investments, including certain intercompany loans, in the U.K. against fluctuations in foreign exchange rates. GBP denominated borrowings under the Sterling term loan and the 2017 Revolving Credit Facility were previously used to hedge a portion of our investments in the U.K. against fluctuations in GBP against the USD. The GBP denominated borrowings under both debt instruments were deemed an effective hedge from issuance in May 2017 until the settlement of the Sterling term loan and the repayment of the GBP denominated borrowings under the 2017 Revolving Credit Facility in March 2021. Concurrent with the settlement of the GBP denominated debt, we entered into four foreign currency forwards with notional amounts totaling £174.0 million, that mature on March 8, 2024 , to hedge a portion of our net investments in the U.K., including an intercompany loan and an investment in our U.K. joint venture, effectively replacing the terminated net investment hedge. On May 17, 2022, we entered into two new foreign currency forward contracts with notional amounts totaling £76.0 million and a GBP-USD forward rate of 1.3071, each of which mature on May 21, 2029. These currency forward contracts hedge a portion of our net investments in U.K. subsidiaries, including an intercompany loan. The location and the fair value of derivative instruments designated as hedges, at the respective balance sheet dates, were as follows: ​ ​ ​ ​ ​ ​ ​ December 31, ​ December 31, ​ 2022 2021 Cash flow hedges: (in thousands) Other assets $ 92,990 ​ $ 32,849 Accrued expenses and other liabilities $ — ​ $ 96 ​ ​ ​ ​ ​ ​ Net investment hedges: ​ ​ ​ ​ ​ Other assets $ 34,977 ​ $ 6,754 ​ The fair value of the interest rate swaps and foreign currency forwards is derived from observable market data such as yield curves and foreign exchange rates and represents a Level 2 measurement on the fair value hierarchy.

The use of different market assumptions and estimation methodologies may have a material effect on the reported estimated fair value amounts. The following methods and assumptions were used in estimating fair value disclosures for financial instruments. ​ ● Real estate loans receivable: The fair value of the real estate loans receivable are estimated using a discounted cash flow analysis, using interest rates being offered for similar loans to borrowers with similar credit ratings (Level 3). ● Non-real estate loans receivable: Non-real estate loans receivable are primarily comprised of notes receivable. The fair values of notes receivable are estimated using a discounted cash flow analysis, using interest rates being offered for similar loans to borrowers with similar credit ratings (Level 3). ● Revolving credit facility, OP term loan, 2023 term loan and 2024 term loan: The carrying amount of these approximate fair value because the borrowings are interest rate adjusted. Differences between carrying value and the fair value in the table above are due to the inclusion of deferred financing costs in the carrying value. ● Senior notes: The fair value of the senior unsecured notes payable was estimated based on (Level 1) publicly available trading prices. ● HUD mortgages: The fair value of our borrowings under HUD debt agreements are estimated using an expected present value technique based on quotes obtained by HUD debt brokers (Level 2).

Taxes [Abstract]
TAXES	NOTE 17 – TAXES Omega and Omega OP, including their wholly-owned subsidiaries were organized, have operated, and intend to continue to operate in a manner that enables Omega to qualify for taxation as a REIT under Sections 856 through 860 of the Code. On a quarterly and annual basis we perform several analyses to test our compliance within the REIT taxation rules. If we fail to meet the requirements for qualification as a REIT in any tax year, we will be subject to federal income tax on our taxable income at regular corporate rates and may not be able to qualify as a REIT for the four We are also subject to federal taxation of 100% of the net income derived from the sale or other disposition of property, other than foreclosure property, that we held primarily for sale to customers in the ordinary course of a trade or business. We believe that we do not hold assets for sale to customers in the ordinary course of business and that none of the assets currently held for sale or that have been sold would be considered a prohibited transaction within the REIT taxation rules. As a REIT under the Code, we generally will not be subject to federal income taxes on the REIT taxable income that we distribute to stockholders, subject to certain exceptions. In 2022, 2021 and 2020, we distributed dividends in excess of our taxable income. We currently own stock in certain subsidiary REITs. These subsidiary entities are required to individually satisfy all of the rules for qualification as a REIT. If we fail to meet the requirements for qualification as a REIT for any of the subsidiary REITs, it may cause the Parent REIT to fail the requirements for qualification as a REIT also. We have elected to treat certain of our active subsidiaries as TRSs. Our domestic TRSs are subject to federal, state and local income taxes at the applicable corporate rates. Our foreign TRSs are subject to foreign income taxes and may be subject to current-year income inclusion relating to ownership of a controlled foreign corporation for U.S. income tax purposes. As of December 31, 2022, one of our TRSs that is subject to income taxes at the applicable corporate rates had a net operating loss (“NOL”) carry-forward of approximately $10.2 million. Our NOL carry-forward was fully reserved as of December 31, 2022, with a valuation allowance due to uncertainties regarding realization. Under current law, NOL carry-forwards generated up through December 31, 2017 may be carried forward for no more than 20 years, and NOL carry-forwards generated in taxable years ended after December 31, 2017, may be carried forward indefinitely. We do not anticipate that such changes will materially impact the computation of Omega’s taxable income, or the taxable income of any Omega entity, including our TRSs. As discussed in Note 3 – Real Estate Asset Acquisitions and Development, in connection with the acquisition of one U.K. entity in the first quarter of 2022, we acquired foreign net operating losses of $55.0 million resulting in a NOL deferred tax asset of $13.4 million. The NOLs have no expiration date and may be available to offset future taxable income. We believe these foreign NOLs are realizable under a “more likely than not” measurement and have not recorded a valuation allowance against the deferred tax asset. The following is a summary of our provision for income taxes: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended December 31, ​ 2022 2021 ​ 2020 ​ ​ (in millions) Provision for federal, state and local income taxes (1) ​ $ 1.2 ​ $ 1.4 ​ $ 1.3 Provision for foreign income taxes (2) ​ ​ 3.4 ​ ​ 2.4 ​ ​ 3.6 Total provision for income taxes (3) ​ $ 4.6 ​ $ 3.8 ​ $ 4.9 (1) For the years ended December 31, 2022, 2021 and 2020, income before income tax expense and income from unconsolidated joint ventures from domestic operations was $418.5 million, $403.9 million and $151.5 million, respectively. (2) For the years ended December 31, 2022, 2021 and 2020, income before income tax expense and income from unconsolidated joint ventures from foreign operations was $17.6 million, $12.2 million and $10.8 million, respectively. (3) The above amounts do not include gross income receipts or franchise taxes payable to certain states and municipalities.

Stockholders Equity [Abstract]
STOCKHOLDERS EQUITY	NOTE 18 – STOCKHOLDERS’ EQUITY Stock Repurchase Program On March 20, 2020, Omega’s Board of Directors authorized the repurchase of up to $200 million of its outstanding common stock from time to time over the twelve months ending March 20, 2021. Omega did no t repurchase any of its outstanding common stock under this announced program during 2020 or 2021. On January 27, 2022, the Company authorized the repurchase of up to $500 million of our outstanding common stock from time to time through March 2025. The Company is authorized to repurchase shares of its common stock in open market and privately negotiated transactions or in any other manner as determined by the Company’s management and in accordance with applicable law. The timing and amount of stock repurchases will be determined, in management’s discretion, based on a variety of factors, including but not limited to market conditions, other capital management needs and opportunities, and corporate and regulatory considerations. The Company has no obligation to repurchase any amount of its common stock, and such repurchases, if any, may be discontinued at any time. Under Maryland law, shares repurchased become authorized but unissued shares. The Company reduced the common stock at par value and to the extent the cost acquired exceeds par value, it is recorded through additional paid-in capital on our Consolidated Balance Sheets and Consolidated Statements of Equity. During the year ended December 31, 2022, the Company repurchased 5.2 million shares of our outstanding common stock at an average price of $27.32 per share, for a total repurchase cost of $142.3 million. The average price per share and repurchase cost includes the cost of commissions. At-The-Market Offering Program On September 3, 2015, we entered into separate Equity Distribution Agreements with several financial institutions to sell $500 million of shares of our common stock from time to time through an “at-the-market” (“ATM”) offering program (the “2015 ATM Program”). Sales of the shares, if any, were made by means of ordinary brokers’ transactions on the New York Stock Exchange at market prices, or as otherwise agreed with the applicable Manager. We paid each Manager compensation for sales of the shares up to 2% of the gross sales price per share for shares sold through such Manager under the applicable Equity Shelf Agreements. During the second quarter of 2021, we terminated the 2015 ATM Program and entered into a new ATM Equity Offering Sales Agreement pursuant to which shares of common stock having an aggregate gross sales price of up to $1.0 billion (the “2021 ATM Program”) may be sold from time to time (i) by Omega through several financial institutions acting as a sales agent or directly to the financial institutions as principals, or (ii) by several financial institutions acting as forward sellers on behalf of any forward purchasers pursuant to a forward sale agreement. Under the 2021 ATM Program, compensation for sales of the shares will not exceed 2% of the gross sales price per share for shares sold through each financial institution. The use of forward sales under the 2021 ATM Program generally allows Omega to lock in a price on the sale of shares of common stock when sold by the forward sellers but defer receiving the net proceeds from such sales until the shares of our common stock are issued at settlement on a later date. We did not utilize the forward provisions under the 2021 ATM Program during 2021 or 2022. The following is a summary of the shares issued under the 2021 and 2015 ATM Programs for each of the years ended December 31, 2020, 2021, and 2022 (in millions except average price per share): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Average Net Price ​ ​ ​ ​ ​ ​ Period Ended Shares issued Per Share (1) Gross Proceeds Commissions Net Proceeds December 31, 2020 4.2 $ 36.16 $ 155.1 $ 2.5 $ 152.6 December 31, 2021 4.2 ​ 36.53 ​ 155.1 ​ 3.4 ​ 151.7 December 31, 2022 — ​ — ​ — ​ — ​ — (1) Represents the average price per share after commissions. Dividend Reinvestment and Common Stock Purchase Plan We have a Dividend Reinvestment and Common Stock Purchase Plan (the “DRSPP”) that allows for the reinvestment of dividends and the optional purchase of our common stock. On March 23, 2020, we temporarily suspended the DRSPP and on December 17, 2020, we reinstated the DRSPP.

STOCK-BASED COMPENSATION

Stock-Based Compensation [Abstract]
STOCK-BASED COMPENSATION	NOTE 19 – STOCK-BASED COMPENSATION At December 31, 2022, we maintained several stock-based compensation plans as described below. For the years ended December 31, 2022, 2021 and 2020, we recognized stock-based compensation of $27.3 million, $21.4 million and $18.8 million, respectively, related to these plans. Time-Based Restricted Equity Awards Restricted stock, restricted stock units (“RSUs”) and profits interest units (“PIUs”) are subject to forfeiture if the holder’s service to us terminates prior to vesting, subject to certain exceptions for certain qualifying terminations of service or a change in control of the Company. Prior to vesting, ownership of the shares/units cannot be transferred. The restricted stock has the same dividend and voting rights as our common stock. RSUs accrue dividend equivalents but have no voting rights. PIUs accrue distributions, which are equivalent to dividend equivalents, but have no voting rights. Once vested, each RSU is settled by the issuance of one share of Omega common stock and each PIU is settled by the issuance of one Omega OP Unit, subject to certain conditions. Restricted stock and RSUs are valued at the price of our common stock on the date of grant. The PIUs are valued using a Monte Carlo model to estimate fair value. We expense the cost of these awards ratably over their vesting period. Performance-Based Restricted Equity Awards Performance-based restricted equity awards include performance restricted stock units (“PRSUs”) and PIUs. PRSUs and PIUs are subject to forfeiture if the performance requirements are not achieved or if the holder’s service to us terminates prior to vesting, subject to certain exceptions for certain qualifying terminations of employment or a change in control of the Company. PRSUs and PIUs have varying degrees of performance requirements to achieve vesting, and each PRSU and PIU award represents the right to a variable number of shares of common stock or partnership units. Each PIU once earned is convertible into one Omega OP Unit in Omega OP, subject to certain conditions. The vesting requirements are based on either the (i) total shareholder return (“TSR”) of Omega or (ii) Omega’s TSR relative to other REITs in the FTSE NAREIT Equity Health Care Index (“Relative TSR”). We expense the cost of these awards ratably over their service period. Prior to vesting and the distribution of shares or Omega OP Units, ownership of the PRSUs or PIUs cannot be transferred. Dividend equivalents on the PRSUs are accrued and paid to the extent the applicable performance requirements are met. While each PIU is unearned, the employee receives a partnership distribution equal to 10% of the quarterly approved regular periodic distributions per Omega OP Unit. Partnership distributions (which in the case of normal periodic distributions is equal to the total approved quarterly dividend on Omega’s common stock), less the 10% already paid, on the PIUs accumulate, and if the PIUs are earned, the accumulated distributions are paid.

In addition, we have a deferred stock compensation plan that allows employees and directors the ability to defer the receipt of stock awards (units). The deferred stock awards (units) participate in future dividend equivalents as well as the change in the value of the Company’s common stock. As of December 31, 2022 and 2021, the Company had 646,871 and 630,623 deferred stock units outstanding. Tax Withholding for Stock Compensation Plans Stock withheld to pay tax withholdings for equity instruments granted under stock-based payment arrangements for the years ended December 31, 2022, 2021 and 2020, was $1.1 million, $4.6 million and $4.7 million, respectively. Shares Available for Issuance for Compensation Purposes On June 8, 2018, at the Annual Meeting of Stockholders, our stockholders approved the 2018 Stock Incentive Plan (the “2018 Plan”), which amended and restated the Company’s 2013 Stock Incentive Plan (the “2013 Plan”). The 2018 Plan is a comprehensive incentive compensation plan that allows for various types of equity-based compensation, including RSUs (including PRSUs), stock awards (including restricted stock), deferred RSUs, incentive stock options, non-qualified stock options, stock appreciation rights, dividend equivalent rights, performance unit awards, certain cash-based awards (including performance-based cash awards), PIUs and other stock-based awards. The 2018 Plan increased the number of shares of common stock available for issuance under the 2013 Plan by 4.5 million. As of December 31, 2022, approximately 1.6 million shares of common stock were reserved for issuance to our employees, directors and consultants under our stock incentive plans.

COMMITMENTS AND CONTINGENCIES [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 20 – COMMITMENTS AND CONTINGENCIES Litigation Shareholder Litigation The Company and certain of its officers, C. Taylor Pickett, Robert O. Stephenson, and Daniel J. Booth Following a mediation, the plaintiffs and defendants reached an agreement in principle on a settlement of the Securities Class Action and thereafter executed a stipulation of settlement dated December 9, 2022 (“Settlement”), subject to the approval of the District Court. On December 27, 2022, the District Court granted preliminary approval of the settlement, and scheduled a hearing for April 25, 2023 on final approval of the Settlement. Pursuant to the preliminary approval order, and subject to final approval by the District Court, the Settlement payment of $30.75 million has been transmitted to an escrow account by the Company’s directors and officers insurers. The Settlement does not include any admission of wrongdoing or liability on the part of the Company or the individual defendants, and upon final approval by the Court, provides for a dismissal of, and a release of all claims against the defendants by a class of persons and/or entities who purchased or otherwise acquired Company securities from February 8, 2017 through October 31, 2017. The Company recorded a $31 million legal reserve related to the Securities Class Action in the third quarter of 2022, which is included within accrued expenses and other liabilities on the Consolidated Balance Sheets. As the Settlement proceeds are to be paid by insurance, the Company concurrently recorded a receivable for $31 million within other assets on the Consolidated Balance Sheet, and consequently there is no impact to the Consolidated Statements of Operations related to this matter. Certain derivative actions have also been brought against the officers named in the Securities Class Action, and certain current and former directors of the Company, alleging claims relating to the matters at issue in the Securities Class Action. These derivative actions are currently stayed pending certain developments in the Securities Class Action. In 2018, Stourbridge Investments LLC, a purported stockholder of the Company, filed a derivative action purportedly on behalf of the Company in the U.S. District Court for the Southern District of New York, alleging violations of Section 14(a) of the Exchange Act and state-law claims including breach of fiduciary duty. The complaint alleges, among other things, that the named defendants are responsible for the Company’s failure to disclose the financial condition of Orianna Health Systems, the alleged non-disclosures that are also the subject of the Securities Class Action described above. The plaintiff did not make a demand on the Company to bring the action prior to filing it, but rather alleges that demand would have been futile. The case has been stayed pending the entry of judgment or a voluntary dismissal with prejudice in the Securities Class Action. In 2019, purported stockholder Phillip Swan by his counsel, and stockholders Tom Bradley and Sarah Smith by their counsel, filed derivative actions in the Baltimore City Circuit Court of Maryland, purportedly on behalf of the Company, asserting claims for breach of fiduciary duty, waste of corporate assets and unjust enrichment against the named defendants. Those actions have been consolidated and stayed in the Maryland court pending completion of fact discovery in the Securities Class Action. Prior to filing suit, each of these stockholders had made demands on the Board of Directors in 2018 that the Company bring such lawsuits. After an investigation and due consideration, and in the exercise of its business judgment, the Board of Directors determined that it is not in the best interests of the Company to commence litigation against any current or former officers or directors based on the matters raised in the demands. In addition, in late 2020, Robert Wojcik, a purported shareholder of the Company, filed a derivative action in the U.S. District Court for the District of Maryland, purportedly on behalf of the Company, asserting violations of Section 14(a) of the Exchange Act, Sections 10(b) and 21D of the Exchange Act, as well as claims for breach of fiduciary duty, unjust enrichment, abuse of control, gross mismanagement, and waste of corporate assets. Wojcik also did not make a demand on the Company prior to filing suit. The case has been stayed pending the entry of judgment or a voluntary dismissal with prejudice in the Securities Class Action. Other Gulf Coast Subordinated Debt In August 2021, we filed suit in the Circuit Court for Baltimore County (the “Court”) against the holders of certain Subordinated Debt (the “Debt Holders”) associated with our Gulf Coast master lease agreement, following an assertion by the holders that our prior exercise of offset rights in connection with Gulf Coast’s non-payment of rent had resulted in defaults under the terms of the Subordinated Debt. The suit seeks a declaratory judgment to, among other items, declare that the aggregate amount of unpaid rent due from Gulf Coast under the master lease agreement exceeds all amounts which otherwise would be due and owing by an indirect subsidiary of Omega (“Omega Obligor”) under the Subordinated Debt, and that all principal and interest due and owing under the Subordinated Debt may be (and was) offset in full as of December 31, 2021. In October 2021, the defendants in the case filed a motion to dismiss for lack of personal jurisdiction. On November 3, 2022, the Court granted the noteholders’ motion to dismiss for lack of personal jurisdiction, and Omega filed a timely appeal of the ruling. While Omega believes Omega Obligor is entitled to the enforcement of the offset rights sought in the action, Omega cannot predict the outcome of the declaratory judgment action, irrespective of whether (a) it is ultimately litigated in the Court if Omega Obligor prevails in its appeal or (b) if the order granting the motion to dismiss for lack of personal jurisdiction is affirmed. On or about January 19, 2023, the Debt Holders served a lawsuit against the Omega Obligor in the Superior Court of the State of Delaware, asserting claims for (i) breach of the instruments evidencing the Subordinated Debt, (ii) declaratory judgment, and (iii) unjust enrichment, all claims that are factually based on the claims that are the subject of Omega Obligor’s suit in the Court and that are now on appeal. On February 8, 2023, Omega Obligor filed a motion to dismiss or, in the alternative, to stay this action pending the outcome of the above referenced lawsuit in Maryland. The motion is presently pending before the Delaware state court. Omega believes that the claims are baseless and is evaluating procedural and substantive legal options in connection with this recently filed suit. Lakeway Realty, L.L.C. In September 2016, MedEquities received a Civil Investigative Demand (“CID”) from the U.S. Department of Justice (“DOJ”), which indicates that it is conducting an investigation regarding alleged violations of the False Claims Act, Stark Law and Anti-Kickback Statute in connection with claims that may have been submitted to Medicare and other federal payors for services rendered to patients at Lakeway Hospital or by providers with financial relationships with Lakeway Hospital (the “Potential Claims”). As a result of the acquisition of MedEquities, the Company owns a 51% interest in an unconsolidated limited liability company that owns Lakeway Hospital, Lakeway Realty, L.L.C. The CID requested certain documents and information related to the acquisition and ownership of Lakeway Hospital through Lakeway Realty, L.L.C. The Company has learned that the DOJ is investigating, among other items, MedEquities’ conduct in connection with its investigation of financial relationships related to Lakeway Hospital, including allegations by the DOJ that these relationships violate and continue to violate the Anti-Kickback Statute and, as a result, related claims submitted to federal payors violated and continue to violate the False Claims Act. On September 29, 2020, the DOJ announced it had reached a settlement of a False Claims Act case with Lakeway Regional Medical Center wherein Lakeway Regional Medical Center agreed to pay $1.1 million for inducing certain physicians to refer patients by offering a low risk and high return investment in the form of a joint venture to purchase and then lease back the hospital to Lakeway Regional Medical Center. A MedEquities subsidiary was a party to this transaction but was not included in settlement discussions, and we understand that the settlement did not fully resolve the investigation referenced in the CID. As of November 7, 2022, Lakeway Realty, L.L.C., one of its members, MRT of Lakeway TX-ACH, LLC, and Omega (together, “Defendants”), the U.S., the State of Texas and certain named relators entered into a settlement agreement pursuant to which Defendants were released from the Potential Claims from March 2, 2015 through August 31, 2016, in exchange for Omega’s agreement to pay approximately $3.1 million. Defendants admitted no liability associated with the Potential Claims. In the second quarter of 2022, the Company recorded a $3.0 million legal reserve related to this matter, which is included in other (expense) income – net on the Consolidated Statements of Operations. The settlement was paid in the fourth quarter of 2022 and Omega has no remaining legal reserves related to this matter as of December 31, 2022. In addition to the matters above, we are subject to various other legal proceedings, claims and other actions arising out of the normal course of business. While any legal proceeding or claim has an element of uncertainty, management believes that the outcome of each lawsuit, claim or legal proceeding that is pending or threatened, or all of them combined, will not have a material adverse effect on our consolidated financial position or results of operations. Indemnification Agreements In connection with certain facility transitions, we have agreed to indemnify certain operators in certain events. As of December 31, 2022, our maximum funding commitment under these indemnification agreements was approximately $5.1 million. Claims under these indemnification agreements generally may be made within 18 months to 72 months of the transition date. These indemnification agreements were provided to certain operators in connection with facility transitions and generally would be applicable in the event that the prior operators do not perform under their transition agreements. Commitments We have committed to fund the construction of new leased and mortgaged facilities, capital improvements and other commitments. We expect the funding of these commitments to be completed over the next several years. Our remaining commitments at December 31, 2022, are outlined in the table below (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Construction and capital expenditure mortgage loan commitments $ 7,269 ​ ​ Lessor construction and capital commitments under lease agreements (1) ​ 203,655 ​ ​ Non-real estate loan commitments (2) ​ 71,353 ​ ​ Total remaining commitments (3) ​ $ 282,277 ​ ​ (1) Includes $93.3 million related to our $177.7 million commitment relating to the redevelopment of the real estate property located in Washington, D.C. discussed in Note 3 – Real Estate Asset Acquisitions and Development. (2) This amount includes $57.0 million related to the $90.0 million short-term revolving line of credit discussed in Note 8 – Non-real Estate Loans Receivable. (3) Includes finance costs .

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2022
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES [Abstract]
Accounting Estimates	Accounting Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.
Basis of Presentation and Principles of Consolidation	Consolidation Omega’s consolidated financial statements include the accounts of (i) Parent, (ii) all direct and indirect wholly-owned subsidiaries of Omega, including Omega OP, (iii) other entities in which Omega or Omega OP has a majority voting interest and control and (iv) variable interest entities (“VIEs”) of which Omega is the primary beneficiary. All intercompany transactions and balances have been eliminated in consolidation, and Omega’s net earnings are reduced by the portion of net earnings attributable to noncontrolling interests. GAAP requires us to identify entities for which control is achieved through means other than voting rights and to determine which business enterprise, if any, is the primary beneficiary of VIEs. A VIE is broadly defined as an entity with one or more of the following characteristics: (a) the total equity investment at risk is insufficient to finance the entity’s activities without additional subordinated financial support; (b) as a group, the holders of the equity investment at risk lack (i) the ability to make decisions about the entity’s activities through voting or similar rights, (ii) the obligation to absorb the expected losses of the entity, or (iii) the right to receive the expected residual returns of the entity; or (c) the equity investors have voting rights that are not proportional to their economic interests, and substantially all of the entity’s activities either involve, or are conducted on behalf of, an investor that has disproportionately few voting rights. We may change our original assessment of a VIE upon subsequent events such as the modification of contractual arrangements that affects the characteristics or adequacy of the entity’s equity investments at risk and the disposition of all or a portion of an interest held by the primary beneficiary. Our variable interests in VIEs may be in the form of equity ownership, leases, guarantees and/or loans with our operators. We analyze our agreements and investments to determine whether our operators or unconsolidated joint ventures are VIEs and, if so, whether we are the primary beneficiary. We consolidate a VIE when we determine that we are its primary beneficiary. We identify the primary beneficiary of a VIE as the enterprise that has both: (i) the power to direct the activities of the VIE that most significantly impact the entity’s economic performance; and (ii) the obligation to absorb losses or the right to receive benefits of the VIE that could be significant to the entity. Factors considered in determining whether we are the primary beneficiary of an entity include: (i) our voting rights, if any; (ii) our involvement in day-to-day capital and operating decisions; (iii) our risk and reward sharing; (iv) the financial condition of the operator or joint venture and (iv) our representation on the VIE’s board of directors. We perform this analysis on an ongoing basis. As of December 31, 2022, we have one joint venture that is a consolidated VIE as we have concluded that we are the primary beneficiary through our equity investment in the entity. We also have consolidated VIEs related to the Exchange Accommodation Titleholders (“EATs”) discussed in Note 3 – Real Estate Asset Acquisitions and Development. As of December 31, 2021, we did not have any VIEs that we consolidated.
Revenue Recognition	Revenue Recognition Rental Income Rental income from operating leases is recognized on a straight-line basis, inclusive of fixed annual escalators and lease inducements, over the lease term when we have determined that the collectibility of substantially all of the lease payments is probable. Certain of our operating leases contain provisions for an increase based on the change in pre-determined formulas from year to year (e.g., increases in the Consumer Price Index). We do not include in our measurement of our lease receivables these variable increases until the specific events that trigger the variable payments have occurred. Our leased real estate properties are leased under provisions of single or master leases with initial terms typically ranging from 5 to 15 years. Some of our leases have options to extend, terminate or purchase the facilities, which are considered when determining the lease term. We assess the probability of collecting substantially all payments due under our leases on several factors, including, among other things, payment history, the financial strength of the lessee and any guarantors, as applicable, historical operations and operating trends, current and future economic conditions, and expectations of performance (which includes known substantial doubt about an operator’s ability to continue as a going concern). If our evaluation of these factors indicates it is probable that we will be unable to collect substantially all rents, we recognize a charge to rental income to write off straight-line rent receivables and limit our rental income to the lesser of lease income on a straight-line basis plus variable rents when they become accruable or cash collected. Provisions for uncollectible lease payments are recognized as a direct reduction to rental income. If we change our conclusion regarding the probability of collecting rent payments required by a lessee, we may recognize an adjustment to rental income in the period we make a change to our prior conclusion, potentially resulting in increased volatility of rental income. Under the terms of our leases, the lessee is responsible for all maintenance, repairs, taxes and insurance on the leased properties. Certain of our operating leases require the operators to reimburse us for property taxes and other expenditures that are not considered components of the lease and therefore no consideration is allocated to them as they do not result in the transfer of a good or service to the operators. We have determined that all of our leases qualify for the practical expedient, under Accounting Standards Codification (“ASC”) 842, Leases (“Topic 842”), to not separate the lease and non-lease components because (i) the lease components are operating leases and (ii) the timing and pattern of recognition of the non-lease components are the same as the lease components. Certain operators are obligated to pay directly their obligations under their leases for real estate taxes, insurance and certain other expenses. These obligations, which have been assumed by the tenants under the terms of their respective leases, are not reflected in our consolidated financial statements. To the extent any tenant responsible for these obligations under their respective lease defaults on its lease or if it is deemed probable that the tenant will fail to pay for such costs, we would record a liability for such obligation. We have elected to exclude sales and other similar taxes from the measurement of lease revenue and expense. Loan Interest Income Interest income is recognized as earned over the term of the related real estate and non-real estate loans receivable. Interest income is recorded on an accrual basis to the extent that such amounts are expected to be collected using the effective interest method. In applying the effective interest method, the effective yield on a loan is determined based on its contractual payment terms, adjusted for prepayment terms. Direct Financing Lease Income As of December 31, 2022, we have one lease for a facility that is classified as a direct financing lease. For leases accounted for as direct financing leases, we record the present value of the future minimum lease payments (utilizing a constant interest rate over the term of the lease agreement) as a receivable and record interest income based on the contractual terms of the lease agreement. Costs related to originating direct financing leases are deferred and amortized on a straight-line basis as a reduction to income from direct financing leases over the term of the direct financing leases. Real Estate Sales We recognize gains on the disposition of real estate when the recognition criteria have been met, generally at the time the risks and rewards and title have transferred, and we no longer have substantial continuing involvement with the real estate sold. Gains on the sale of real estate are recognized pursuant to provisions under Accounting Standards Codification (“ASC”) 610-20, Gains and Losses from the Derecognition of Nonfinancial Assets. Under ASC 610-20, we determine whether the transaction is a sale to a customer or non-customer. As a REIT, we do not sell real estate within the ordinary course of our business and therefore, expect that our sale transactions will not be contracts with customers. ASC 610-20 refers to the revenue recognition principles under ASC 606, Revenue from Contracts with Customers. Under ASC 610-20, if we determine we do not have a controlling financial interest in the entity that holds the asset and the arrangement meets the criteria to be accounted for as a contract, we will dispose of the asset and recognize a gain or loss on the sale of the real estate when control of the underlying asset transfers to the buyer. If we determine a sale has not occurred under ASC 610-20, we continue to record the asset on the Consolidated Balance Sheets and related depreciation expense on the Consolidated Statements of Operations.
Fair Value Measurement	Fair Value Measurement The Company measures and discloses the fair value of nonfinancial and financial assets and liabilities utilizing a hierarchy of valuation techniques based on whether the inputs to a fair value measurement are considered to be observable or unobservable in a marketplace. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. This hierarchy requires the use of observable market data when available. These inputs have created the following fair value hierarchy: ● Level 1 - quoted prices for identical instruments in active markets; ● Level 2 - quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which significant inputs and significant value drivers are observable in active markets; and ● Level 3 - fair value measurements derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. The Company measures fair value using a set of standardized procedures that are outlined herein for all assets and liabilities which are required to be measured at fair value. When available, the Company utilizes quoted market prices from an independent third-party source to determine fair value and classifies such items in Level 1. In some instances where a market price is available, but the instrument is in an inactive or over-the-counter market, the Company consistently applies the dealer (market maker) pricing estimate and classifies such items in Level 2. If quoted market prices or inputs are not available, fair value measurements are based upon valuation models that utilize current market or independently sourced market inputs, such as interest rates, option volatilities, credit spreads and/or market capitalization rates. Items valued using such internally-generated valuation techniques are classified according to the lowest level input that is significant to the fair value measurement. As a result, these items could be classified in either Level 2 or Level 3 even though there may be some significant inputs that are readily observable. Internal fair value models and techniques used by the Company include discounted cash flow and Monte Carlo valuation models.
Risks and Uncertainties including COVID-19	Risks and Uncertainties including COVID-19 The Company is subject to certain risks and uncertainties affecting the healthcare industry, including those stemming from the novel coronavirus (“COVID-19”) global pandemic, which has disproportionately impacted the senior care sector, as well as those stemming from healthcare legislation and changing regulation by federal, state and local governments. Additionally, we are subject to risks and uncertainties as a result of changes affecting operators of nursing home facilities due to the actions of governmental agencies and insurers to limit the rising cost of healthcare services.
Real Estate Acquisitions	Real Estate Acquisitions Upon acquisition of real estate properties, we evaluate the acquisition to determine if it is a business combination or an asset acquisition. Our real estate acquisitions are generally accounted for as asset acquisitions as substantially all of the fair value of the gross assets acquired is concentrated in a single identifiable asset or group of similar identifiable assets. If the acquisition is determined to be an asset acquisition, the Company records the purchase price and other related costs incurred to the acquired tangible assets and identified intangible assets and liabilities on a relative fair value basis. In addition, costs incurred for asset acquisitions including transaction costs, are capitalized. If the acquisition is determined to be a business combination, we record the purchase of properties to net tangible and identified intangible assets acquired and liabilities assumed at fair value. Goodwill is measured as the excess of the fair value of the consideration transferred over the fair value of the identifiable net assets. Transaction costs are expensed as incurred as part of a business combination. In making estimates of fair value for purposes of recording asset acquisitions and business combinations, we utilize a number of sources, including independent appraisals that may be obtained in connection with the acquisition or financing of the respective property and other market data. The Company determines the fair value of acquired assets and liabilities as follows: ● Land is determined based on third-party appraisals which typically include market comparables. ● Buildings and site improvements acquired are valued using a combination of discounted cash flow projections that assume certain future revenues and costs and consider capitalization and discount rates using current market conditions as well as the residual approach. ● Furniture and fixtures are determined based on third-party appraisals which typically utilize a replacement cost approach. ● Mortgages and other investments are valued using a discounted cash flow analysis, using interest rates being offered for similar loans to borrowers with similar credit ratings. ● Investments in joint ventures are valued based on the fair value of the joint ventures’ assets and liabilities. Differences, if any, between the Company’s basis and the joint venture’s basis are generally amortized over the lives of the related assets and liabilities, and such amortization is included in the Company’s share of earnings (losses) of the joint venture. ● Intangible assets and liabilities acquired are valued using a combination of discounted cash flow projections as well as other valuation techniques based on current market conditions for the intangible asset or liability being acquired. When evaluating below market leases we consider extension options controlled by the lessee in our evaluation. ● Other assets acquired and liabilities assumed are typically valued at stated amounts, which approximate fair value on the date of the acquisition. ● Assumed debt balances are valued by discounting the remaining contractual cash flows using a current market rate of interest. ● Noncontrolling interests are valued using a stock price on the acquisition date.
Real Estate Properties	Real Estate Properties Real estate properties are carried at initial recorded value less accumulated depreciation. The costs of significant improvements, renovations and replacements, including interest are capitalized. Our interest expense reflected in the Consolidated Statements of Operations has been reduced by the amounts capitalized. For the years ended December 31, 2022, 2021 and 2020, we capitalized $3.2 million, $1.5 million and $10.0 million, respectively, of interest to our projects under development. In addition, we capitalize leasehold improvements when certain criteria are met, including when we supervise construction and will own the improvement. Expenditures for maintenance and repairs are expensed as they are incurred. Depreciation is computed on a straight-line basis over the estimated useful lives ranging from 20 to 40 years for buildings, eight three Management evaluates our real estate properties for impairment indicators at each reporting period, including the evaluation of our assets’ useful lives. The judgment regarding the existence of impairment indicators is based on factors such as, but not limited to, market conditions, operator performance including the current payment status of contractual obligations and expectations of the ability to meet future contractual obligations, legal structure, as well as our intent with respect to holding or disposing of the asset. If indicators of impairment are present, management evaluates the carrying value of the related real estate investments in relation to management’s estimate of future undiscounted cash flows of the underlying facilities. The estimated future undiscounted cash flows are generally based on the related lease which relates to one or more properties and may include cash flows from the eventual disposition of the asset. In some instances, there may be various potential outcomes for a real estate investment and its potential future cash flows. In these instances, the undiscounted future cash flows used to assess the recoverability of the assets are probability-weighted based on management’s best estimates as of the date of evaluation. Impairment losses related to long-lived assets are recognized when expected future undiscounted cash flows based on our intended use of the property are determined to be less than the carrying values of the assets. An adjustment is made to the net carrying value of the real estate investments for the excess of carrying value over fair value. The fair value of the real estate investment is determined based on current market conditions and considers matters such as rental rates and occupancies for comparable properties, recent sales data for comparable properties, and, where applicable, contracts or the results of negotiations with purchasers or prospective purchasers. Additionally, our evaluation of fair value may consider valuing the property as a nursing home or other healthcare facility as well as alternative uses. All impairments are taken as a period cost at that time, and depreciation is adjusted going forward to reflect the new value assigned to the asset. Management’s impairment evaluation process, and when applicable, impairment calculations involve estimation of the future cash flows from management’s intended use of the property as well as the fair value of the property. Changes in the facts and circumstances that drive management’s assumptions may result in an impairment to our assets in a future period that could be material to our results of operations.
Assets Held for Sale	Assets Held for Sale We consider properties to be assets held for sale when (1) management commits to a plan to sell the property; (2) it is unlikely that the disposal plan will be significantly modified or discontinued; (3) the property is available for immediate sale in its present condition; (4) actions required to complete the sale of the property have been initiated; (5) sale of the property is probable and we expect the completed sale will occur within one year; and (6) the property is actively being marketed for sale at a price that is reasonable given our estimate of current market value. Upon designation of a property as an asset held for sale, we record the property’s value at the lower of its carrying value or its estimated fair value, less estimated costs to sell, and we cease depreciation.
Lessee Accounting	Lessee Accounting Omega leases real estate (corporate headquarters and certain other facilities), office equipment and is party to certain ground leases on our owned facilities. We determine if an arrangement is or contains a lease at inception. Leases are classified as either finance or operating at inception of the lease. Short-term leases, defined as leases with an initial term of 12 months or less that do not contain a purchase option, are not recorded on the balance sheet. Lease expense for short-term leases is recognized on a straight-line basis over the lease term. As of December 31, 2022 and 2021, all of the leases where we are the lessee were classified as operating leases. We have leases that contain both lease and non-lease components and have elected, as an accounting policy, to not separate lease components and non-lease components. Operating and finance lease right-of-use ("ROU") assets and liabilities are recognized at the commencement date based on the present value of lease payments over the lease term. Our ROU assets and lease liabilities are included in other assets and accrued expenses and other liabilities, respectively, on our Consolidated Balance Sheets. The lease liability is calculated as the present value of the remaining minimum rental payments for existing leases using either the rate implicit in the lease or, if none exists, the Company's incremental borrowing rate, as the discount rate. Certain leases have options to extend, terminate or purchase the asset and have been considered in our analysis of the lease term and the measurement of the ROU assets and lease liabilities. On a quarterly basis, we record our lease liabilities at the present value of the future lease payments using the discount rate determined at lease commencement. Rental expense from operating leases is generally recognized on a straight-line basis over the lease term. Lease expense derived from our operating leases is recorded in general and administrative in our Consolidated Statements of Operations. We do not include in our measurement of our lease liability certain variable payments, including changes in an index until the specific events that trigger the variable payments have occurred. We record on a straight-line basis rental income and ground lease expense for those assets we lease and are reimbursed by our operators and/or are paid for directly by our operators.
In-Place Leases	In-Place Leases In-place lease assets and liabilities result when we assume a lease as part of an asset acquisition or business combination. The fair value of in-place leases consists of the following components, as applicable (1) the estimated cost to replace the leases and (2) the above or below market cash flow of the leases, determined by comparing the projected cash flows of the leases in place at the time of acquisition to projected cash flows of comparable market-rate leases. Above market leases, net of accumulated amortization, are included in other assets on our Consolidated Balance Sheets. Below market leases, net of accumulated amortization, are included in accrued expenses and other liabilities on our Consolidated Balance Sheets. The net amortization related to the above and below market leases is included in our Consolidated Statements of Operations as an adjustment to rental income over the estimated remaining term of the underlying leases. Should a tenant terminate the lease, the unamortized portion of the lease intangible is recognized immediately as an adjustment to rental income.
Allowance for Credit Losses	Allowance for Credit Losses The allowance for credit losses reflects our current estimate of the potential credit losses on our real estate loans, non-real estate loans, and our investment in direct financing leases and is recorded as a valuation account as a direct offset against these financial instruments on our Consolidated Balance Sheets. Expected credit losses inherent in non-cancelable unfunded loan commitments are accounted for as separate liabilities included in accrued expenses and other liabilities on the Consolidated Balance Sheets. The Company has elected to not measure an allowance for credit losses on accrued interest receivables related to all of its real estate loans and non-real estate loans because we write off uncollectible accrued interest receivable in a timely manner pursuant to our non-accrual policy, described below. Changes to the allowance for credit losses on loans resulting from quarterly evaluations are recorded through provision for credit losses on the Consolidated Statements of Operations. We assess the creditworthiness of our borrowers on a quarterly basis. For purposes of determining our allowance for credit loss, we pool financial assets that have similar risk characteristics. We aggregate our financial assets by financial instrument type (i.e. real estate loan, non-real estate loan, etc.) and by our internal risk rating. Our internal credit ratings consider several factors including the collateral and/or security, the performance of borrowers underlying facilities, if applicable, available credit support (e.g., guarantees), borrowings with third parties, and other ancillary business ventures and real estate operations of the borrower. Our internal ratings range between 1 and 7. An internal rating of 1 reflects the lowest likelihood of loss and a 7 reflects the highest likelihood of loss. The characteristics associated with each risk rating is as follows: ● Risk Rating 1 through 3 – Instruments with minimal to marginally acceptable risk. ● Risk Rating 4 - Instruments with potential weaknesses identified (Special mention). ● Risk Rating 5 - Instruments with well-defined weaknesses that may result in possible losses (Substandard). ● Risk Rating 6 – Instruments that are unlikely to be repaid in full and will probably result in losses (Doubtful). ● Risk Rating 7 – Instrument that will not be repaid in full and losses will occur (Loss). Periodically, the Company may identify an individual loan for impairment. A loan is considered impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due as scheduled according to the contractual terms of the loan agreements. Our assessment of collectibility considers several factors, including, among other things, payment history, the financial strength of the borrower and any guarantors, historical operations and operating trends, current and future economic conditions, expectations of performance (which includes known substantial doubt about an operator’s ability to continue as a going concern) and the fair value of the underlying collateral of the agreement, a Level 3 measurement, if any. Consistent with this definition, all loans on non-accrual status may be deemed impaired. To the extent circumstances improve and the risk of collectibility is diminished, we will return these loans to full accrual status. When we identify a loan impairment, the loan is written down to the present value of the expected future cash flows or to the fair value of the underlying collateral. Financial instruments are charged off against the allowance for credit losses when collectibility is determined to be permanently impaired. We account for impaired loans using (a) the cost-recovery method, and/or (b) the cash basis method. We generally utilize the cost-recovery method for impaired loans for which impairment reserves were recorded. Under the cost-recovery method, we apply cash received against the outstanding loan balance prior to recording interest income. Under the cash basis method, we apply cash received to principal or interest income based on the terms of the agreement.
Investments in Unconsolidated Joint Ventures	Investments in Unconsolidated Joint Ventures We account for our investments in unconsolidated joint ventures using the equity method of accounting as we exercise significant influence, but do not control the entities. Under the equity method of accounting, the net equity investments of the Company are reflected in the accompanying Consolidated Balance Sheets and the Company’s share of net income and comprehensive income from the joint ventures are included in the accompanying Consolidated Statements of Operations and Consolidated Statements of Comprehensive Income, respectively. On a periodic basis, management assesses whether there are any indicators that the value of the Company’s investments in the unconsolidated joint ventures may be other-than-temporarily-impaired. An investment is impaired only if management’s estimate of the value of the investment is less than the carrying value of the investment, and such a decline in value is deemed to be other than-temporary. To the extent impairment has occurred, the loss is measured as the excess of the carrying amount of the investment over the estimated fair value of the investment. The estimated fair value of the investment is determined using a discounted cash flow model which is a Level 3 valuation. We consider a number of assumptions that are subject to economic and market uncertainties including, among others, rental rates, operating costs, capitalization rates, holding periods and discount rates. No impairment losses on our investments in unconsolidated joint ventures were recognized for the last three fiscal years.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and highly liquid investments with a maturity date of three months or less when purchased. These investments are stated at cost, which approximates fair value. The majority of our cash, cash equivalents and restricted cash are held at major commercial banks. Certain cash account balances exceed FDIC insurance limits of $250,000 per account and, as a result, there is a concentration of credit risk related to amounts in excess of the insurance limits. We regularly monitor the financial stability of these financial institutions and believe that we are not exposed to any significant credit risk in cash, cash equivalents or restricted cash.
Restricted Cash	Restricted Cash Restricted cash consists primarily of liquidity deposits escrowed for tenant obligations required by us pursuant to certain contractual terms and other deposits required by the U.S. Department of Housing and Urban Development (“HUD”) in connection with our mortgage borrowings guaranteed by HUD.
Deposits	Deposits We obtain liquidity deposits and other deposits, security deposits and letters of credit from certain operators pursuant to our lease and mortgage agreements. These generally represent the rental and/or mortgage interest for periods ranging from three The liquidity deposits and other deposits, security deposits and the letters of credit may be used in the event of lease and/or loan defaults, subject to applicable limitations under bankruptcy law with respect to operators filing under Chapter 11 of the U.S. Bankruptcy Code. Liquidity deposits and other deposits are recorded as restricted cash on our Consolidated Balance Sheets with the offset recorded as a liability in accrued expenses and other liabilities on our Consolidated Balance Sheets. Security deposits related to cash received from the operators are primarily recorded in cash and cash equivalents on our Consolidated Balance Sheets with a corresponding offset in accrued expenses and other liabilities on our Consolidated Balance Sheets. Additional security for rental and loan interest revenue from operators is provided by covenants regarding minimum working capital and net worth, liens on accounts receivable and other operating assets of the operators, provisions for cross-default, provisions for cross-collateralization and by corporate or personal guarantees.
Goodwill Impairment	Goodwill Impairment We test goodwill for potential impairment at least annually in the fourth quarter, or more frequently if an event or other circumstance indicates that we may not be able to recover the carrying amount of the net assets of the reporting unit. In evaluating goodwill for impairment, we may assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If we bypass the qualitative assessment, or if we conclude that it is more likely than not that the fair value of a reporting unit is less than its carrying value, then we perform a quantitative impairment test by comparing the fair value of a reporting unit with its carrying amount. In evaluating goodwill for impairment, we assess qualitative factors such as a significant decline in real estate valuations, current macroeconomic conditions, state of the equity and capital markets and our overall financial and operating performance or a significant decline in the value of our market capitalization, to determine whether it is more likely than not that the fair value of our reporting unit is less than its carrying amount. Goodwill is not deductible for tax purposes. We have had no goodwill impairment charges for the last three fiscal years.
Income Taxes	Income Taxes Omega and its wholly-owned subsidiaries were organized to qualify for taxation as a REIT under Section 856 through 860 of the Internal Revenue Code (“Code”). As long as we qualify as a REIT, we will not be subject to federal income taxes on the REIT taxable income that we distributed to stockholders, subject to certain exceptions. However, with respect to certain of our subsidiaries that have elected to be treated as taxable REIT subsidiaries (“TRSs”), we record income tax expense or benefit, as those entities are subject to federal income tax similar to regular corporations. Omega OP is a pass-through entity for U.S. federal income tax purposes. We account for deferred income taxes using the asset and liability method and recognize deferred tax assets and liabilities for the expected future tax consequences of events that have been included in our financial statements or tax returns. Under this method, we determine deferred tax assets and liabilities based on the differences between the financial reporting and tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. Any increase or decrease in the deferred tax liability that results from a change in circumstances, and that causes us to change our judgment about expected future tax consequences of events, is included in the tax provision when such changes occur. Deferred income taxes also reflect the impact of operating loss and tax credit carry-forwards. A valuation allowance is provided if we believe it is more likely than not that all or some portion of the deferred tax asset will not be realized. Any increase or decrease in the valuation allowance that results from a change in circumstances, and that causes us to change our judgment about the realizability of the related deferred tax asset, is included in the tax provision when such changes occur. We are subject to certain state and local income tax, franchise taxes and foreign taxes. The expense associated with these taxes are included in income tax expense on the Consolidated Statements of Operations.
Stock-Based Compensation	Stock-Based Compensation We recognize stock-based compensation expense adjusted for estimated forfeitures to employees and directors, in general and administrative in our Consolidated Statements of Operations on a straight-line basis over the requisite service period of the awards.
Deferred Financing Costs and Original Issuance Premium and/or Discounts for Debt Issuance	Deferred Financing Costs and Original Issuance Premium and/or Discounts for Debt Issuance External costs incurred from the placement of our debt are capitalized and amortized on a straight-line basis over the terms of the related borrowings which approximates the effective interest method. Deferred financing costs related to our revolving line of credit are included in other assets on our Consolidated Balance Sheets and deferred financing costs related to our other borrowings are included as a direct deduction from the carrying amount of the related liability on our Consolidated Balance Sheets. Original issuance premium or discounts reflect the difference between the face amount of the debt issued and the cash proceeds received and are amortized on a straight-line basis over the term of the related borrowings. All premiums and discounts are recorded as an addition to or reduction from debt on our Consolidated Balance Sheets. Amortization of deferred financing costs and original issuance premiums or discounts totaled $12.9 million, $12.3 million and $10.1 million for the years ended December 31, 2022, 2021 and 2020, respectively, and are recorded in interest expense on our Consolidated Statements of Operations. When financings are terminated, unamortized deferred financing costs and unamortized premiums or discounts, as well as charges incurred for the termination, are recognized as expense or income at the time the termination is made. Gains and losses from the extinguishment of debt are presented in loss on debt extinguishment on our Consolidated Statements of Operations.
Earnings Per Share	Earnings Per Share The computation of basic earnings per share/unit (“EPS”) is computed by dividing net income available to common stockholders by the weighted-average number of shares of common stock outstanding during the relevant period. Diluted EPS is computed using the treasury stock method, which is net income divided by the total weighted-average number of common outstanding shares plus the effect of dilutive common equivalent shares during the respective period. Dilutive common shares reflect the assumed issuance of additional common shares pursuant to certain of our share-based compensation plans, including restricted stock and profit interest units, performance restricted stock and profit interest units, the assumed issuance of additional shares related to Omega OP Units held by outside investors.
Noncontrolling Interests and Redeemable Limited Partnership Unitholder Interests	Noncontrolling Interests and Redeemable Limited Partnership Unitholder Interests Noncontrolling interests is the portion of equity not attributable to the respective reporting entity. We present the portion of any equity that we do not own in consolidated entities as noncontrolling interests and classify those interests as a component of total equity, separate from total stockholders’ equity on our Consolidated Balance Sheets. We include net income attributable to the noncontrolling interests in net income in our Consolidated Statements of Operations. As our ownership of a controlled subsidiary increases or decreases, any difference between the aggregate consideration paid to acquire the noncontrolling interests and our noncontrolling interest balance is recorded as a component of equity in additional paid-in capital, so long as we maintain a controlling ownership interest. The noncontrolling interest for Omega represents the outstanding Omega OP Units held by outside investors and interests in a consolidated real estate joint venture not fully owned by Omega. Each of the Omega OP Units (other than the Omega OP Units owned by Omega) is redeemable at the election of the Omega OP Unit holder for cash equal to the then-fair market value of one share of Omega common stock, par value $0.10 per share (“Omega Common Stock”), subject to Omega’s election to exchange the Omega OP Units tendered for redemption for unregistered shares of Omega Common Stock on a one-for-one basis, subject to adjustment as set forth in Omega OP’s partnership agreement. As of December 31, 2022, Omega owns approximately 97% of the issued and outstanding Omega OP Units, and investors own approximately 3% of the outstanding Omega OP Units.
Foreign Operations	Foreign Operations The U.S. dollar (“USD”) is the functional currency for our consolidated subsidiaries operating in the U.S. The functional currency for our consolidated subsidiaries operating in the U.K. is the British Pound (“GBP”). Total revenues from our consolidated U.K. operating subsidiaries were $47.7 million, $38.1 million and $34.8 million for the years ended December 31, 2022, 2021 and 2020, respectively. Our consolidated U.K. operating subsidiaries held long-lived assets of $453.4 million and $387.2 million as of December 31, 2022 and 2021, respectively. For our consolidated subsidiaries whose functional currency is not the USD, we translate their financial statements into the USD. We translate the balance sheet accounts at the exchange rate in effect as of the financial statement date. The income statement accounts are translated using an average exchange rate for the period. Gains and losses resulting from translation are included in accumulated other comprehensive income (loss) (“AOCI”), as a separate component of equity and a proportionate amount of gain or loss is allocated to noncontrolling interests, if applicable. We and certain of our consolidated subsidiaries may have intercompany and third-party debt that is not denominated in the entity’s functional currency. When the debt is remeasured against the functional currency of the entity, a gain or loss can result. The resulting adjustment is reflected in results of operations within other expense - net, unless it is intercompany debt that is deemed to be long-term in nature in which case the adjustments are included in AOCI and a proportionate amount of gain or loss is allocated to noncontrolling interests, if applicable.
Derivative Instruments	Derivative Instruments We are exposed to, among other risks, the impact of changes in foreign currency exchange rates as a result of our investments in the U.K. and interest rate risk related to our capital structure. As a matter of policy, we do not use derivatives for trading or speculative purposes. Our risk management program is designed to manage the exposure and volatility arising from these risks, and utilizes foreign currency forward contracts, interest rate swaps and debt issued in foreign currencies to offset a portion of these risks. To qualify for hedge accounting, derivative instruments used for risk management purposes must effectively reduce the risk exposure that they are designed to hedge. We formally document all relationships between hedging instruments and hedged items, as well as our risk-management objectives and strategy for undertaking various hedge transactions. This process includes designating all derivatives that are part of a hedging relationship to specific forecasted transactions as well as recognized liabilities or assets on the Consolidated Balance Sheets. In addition, at the inception of a qualifying cash flow hedging relationship, the underlying transaction or transactions, must be, and are expected to remain, probable of occurring in accordance with the Company’s related assertions. The Company recognizes all derivative instruments, including embedded derivatives required to be bifurcated, as assets or liabilities on the Consolidated Balance Sheets at fair value which is determined using a market approach and Level 2 inputs. Changes in the fair value of derivative instruments that are not designated in hedging relationships or that do not meet the criteria of hedge accounting are recognized in the Consolidated Statements of Operations. For derivatives designated in qualifying cash flow hedging relationships, the gain or loss on the derivative is recognized in AOCI as a separate component of equity and a proportionate amount of gain or loss is allocated to noncontrolling interest, if applicable. If it is determined that a derivative instrument ceases to be highly effective as a hedge, or that it is probable the underlying forecasted transaction will not occur, the Company discontinues its cash flow hedge accounting prospectively and records the appropriate adjustment to earnings based on the current fair value of the derivative instrument. For net investment hedge accounting, upon sale or liquidation of our U.K. investment, the cumulative balance of the remeasurement value is reclassified to the Consolidated Statements of Operations.
Segments	Segments We conduct our operations and report financial results as one business segment. The presentation of financial results as one reportable segment is consistent with the way we operate our business and is consistent with the manner in which our Chief Operating Decision Maker (CODM), our Chief Executive Officer, evaluates performance and makes resource and operating decisions for the business.
Reclassification	Reclassifications Certain line items on our Consolidated Balance Sheets, Consolidated Statements of Operations and Consolidated Statements of Cash Flows have been reclassified to conform to the current period presentation. Effective for the fourth quarter of 2022, Mortgage notes receivable - net has been renamed Real estate loans receivable - net, Other investments - net has been renamed Non-real estate loans receivable - net, and certain loans have been reclassified out of Other Investments - net into Real estate loans receivable - net. Specifically, other real estate loans collateralized by second or third mortgage liens, a leasehold mortgage on, or an assignment of partnership interest in the related properties that were previously presented in Other Investments - net are now presented in Real estate loans receivable - net.

See further discussion on the held for sale reclassification in Note 4 – Assets Held for Sale.
Recent Accounting Pronouncements	Recently Adopted Accounting Pronouncements ASU – 2021 -05, Leases (Topic 842): Lessors – Certain Leases with Variable Lease Payments On July 19, 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-05. This guidance requires lessors to classify leases with variable lease payments, that do not depend on an index or rate, as an operating lease on the commencement date of the lease if specified criteria are met. The guidance is effective for fiscal years beginning after December 15, 2021, including interim periods within those fiscal years. Early adoption is permitted. We early adopted this guidance prospectively effective July 1, 2021. The adoption of the guidance did not have an impact on our consolidated financial statements. ASU – 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures On March 31, 2022, the FASB issued ASU 2022-02, which eliminates the recognition and measurement guidance for troubled debt restructurings (“TDRs”) and requires additional disclosures for certain loan modifications. ASU 2022-02 also requires entities to disclose gross write-offs of financing receivables and net investments in leases by year of origination. Omega elected to early adopt ASU 2022-02 on a prospective basis effective January 1, 2022. During 2022, we had three loan modifications with two borrowers experiencing financial difficulty pursuant to ASU 2022-02, Guardian Healthcare (“Guardian”) and LaVie Care Centers, LLC (“LaVie,” f/k/a Consulate Health Care), that require additional disclosures. The required disclosures for these loans are included in Note 5 – Contractual Receivables and Other Receivables and Lease Inducements, Note 7 – Real Estate Loans Receivable and Note 8 – Non-real Estate Loans Receivable. We have disclosed our gross write-offs of financing receivables and direct financing leases by year of origination in Note 9 – Allowance for Credit Losses. ASU – 2020-04, Financial Instruments – Reference Rate Reform (Topic 848) On March 12, 2020, the FASB issued ASU 2020-04, which contains optional practical expedients for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting for contracts, hedging relationships, and other transactions that reference the London Interbank Offered Rate (“LIBOR”). The guidance may be elected over time until December 31, 2022, as reference rate reform activities occur. In December 2022, the FASB issued ASU 2022-06, Reference Rate Reform (Topic 848): Deferral of the Sunset Date of Topic 848, which extended the practical expedients under ASU 2020-04 to December 31, 2024. The Company has several derivative instruments (See Note 15 – Derivatives and Hedging), a $1.45 billion senior unsecured multicurrency revolving credit facility, and a $50 million senior unsecured term loan facility (See Note 14 – Borrowing Arrangements) that reference LIBOR. Beginning in the first quarter of 2020, we elected to apply the hedge accounting expedients related to probability and the assessments of effectiveness for future LIBOR indexed cash flows to assume that the index upon which future hedged transactions will be based matches the index on the corresponding derivatives. Application of these expedients preserves the presentation of derivatives consistent with past presentation. Our credit facilities that reference LIBOR contain customary LIBOR replacement language, including, but not limited to, the use of rates based on the secured overnight financing rate. The Company is evaluating: (i) how the transition away from LIBOR will impact the Company, (ii) whether any additional optional expedients provided by the standards will be adopted, and (iii) the impact that adopting ASU 2020-04 will have on our consolidated financial statements. ASU – 2016-13, Financial Instruments - Credit Losses (Topic 326) In June 2016, the FASB issued ASU 2016-13, which changed the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for credit losses. The new approach requires the calculation of expected lifetime credit losses and is applied to financial assets measured at amortized cost, including loans, as well as certain off-balance sheet credit exposures such as unfunded loan commitments. The allowance for credit loss on the loans is a valuation amount that is deducted from the amortized cost basis of the loans not held at fair value to present the net amount expected to be collected over the contractual term of the loans. ASU 2016-13 specifically excludes from its scope receivables arising from operating leases accounted for under Topic 842.

(2) The total consideration paid for the one -facility U.K. acquisition and the 27 -facility U.K. acquisition was $8.2 million and $100.0 million, respectively . In connection with these acquisitions, we allocated $0.5 million of the purchase consideration to a deferred tax liability related to the one -facility U.K. acquisition, and $13.4 million to a deferred tax asset related to the 27 -facility U.K. acquisition. See Note 17 – Taxes for additional information. (3) Total consideration for the one -facility Maryland acquisition was paid on December 30, 2021, but the closing of the acquisition did not occur until January 1, 2022. (4) During the fourth quarter of 2022, we acquired seven facilities using a reverse like-kind exchange structure pursuant to Section 1031 of the Code (a “reverse 1031 exchange”). As of December 31, 2022, we had completed the reverse 1031 exchange for three of the acquired facilities and the remaining four acquired facilities remained in the possession of the EATs. The EATs were classified as VIEs as they do not have sufficient equity investment at risk to permit the entity to finance its activities. The Company consolidated the EATs because it had the ability to control the activities that most significantly impacted the economic performance of the EATs and was, therefore, the primary beneficiary of the EATs. The properties held by the EATs were reflected as real estate with a carrying value of $55.2 million as of December 31, 2022. The EATs also held cash of $23.9 million as of December 31, 2022.

This amount also reflects $4.5 million of additional allowance recorded in the second quarter of 2021 to fully impair one real estate loan receivable with a rating of 4 that was subsequently reduced to a rating of 6 in the third quarter of 2021. (2) Amount reflects the movement of $22.7 million of reserves from non-real estate loans receivable with a rating of 4 to non-real estate loans receivable with a rating of 6 as a result of a reduction of our internal credit rating from a 4 to a 6 on the Agemo Term Loan during the third quarter of 2021. Concurrent with reducing the risk rating on the Agemo Term Loan to a 6, we recorded an additional provision of $8.8 million to fully reserve the remaining carrying value of the Agemo Term Loan. See Note 8 – Non-real Estate Loans Receivable for additional information on the conditions that drove the additional Agemo Term Loan provision and rating reduction. (3) The provision includes an additional $7.9 million allowance recorded on the Agemo WC Loan during the third quarter of 2021. We also reduced the internal rating on the Agemo WC Loan from a 4 to a 5 during the third quarter of 2021.
