Organization, Consolidation and Presentation Of Financial Statements [Abstract]
ORGANIZATION AND BASIS OF PRESENTATION	NOTE 1 - ORGANIZATION AND BASIS OF PRESENTATION Organization Omega Healthcare Investors, Inc. (“Omega”) was formed as a real estate investment trust (“REIT”) and incorporated in the State of Maryland on March 31, 1992. Omega 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 (“Omega OP”). Omega OP was formed as a limited partnership and organized in the State of Delaware on October 24, 2014. Unless stated otherwise or the context otherwise requires, the terms the “Company,” “we,” “our” and “us” means Omega and Omega OP, collectively. ​ The Company has one reportable segment consisting of investments 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”), and rehabilitation and acute care facilities (“specialty facilities”) and medical office buildings (“MOBs”). Our core portfolio consists of long-term leases and mortgage agreements. All of our leases are “triple-net” leases, which require the operators (we use the term “operator” to refer to our tenants and mortgagors and their affiliates who manage and/or operate our properties) to pay all property-related expenses. Our mortgage revenue derives from fixed rate mortgage loans, which are secured by first mortgage liens on the underlying real estate and personal property of the mortgagor. Our other investment income derives from fixed and variable rate loans to our operators and/or their principals to fund working capital and capital expenditures. These loans, which may be either unsecured or secured by the collateral of the borrower, are classified as other investments. ​ Omega OP is governed by the Second Amended and Restated Agreement of Limited Partnership of OHI Healthcare Properties Limited Partnership, dated as of April 1, 2015 (the “Partnership Agreement”). Omega has exclusive control over Omega OP’s day-to-day management pursuant to the Partnership Agreement. As of December 31, 2019, Omega 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. On May 17, 2019, Omega and Omega OP completed their merger with MedEquities Realty Trust, Inc. (“MedEquities”) and its subsidiary operating partnership and the general partner of its subsidiary operating partnership. Pursuant to the Agreement and Plan of Merger, as amended by the First Amendment to the Agreement and Plan of Merger, dated March 26, 2019, (the “Merger Agreement”) Omega acquired MedEquities and MedEquities was merged with and into Omega (the “Merger”) at the effective time of the Merger with Omega continuing as the surviving company. At the effective time, each outstanding share of MedEquities common stock was converted into the right to receive (i) 0.235 of a share of Omega common stock, plus cash in lieu of fractional shares, and (ii) $2.00 in cash. Pursuant to the Merger Agreement, MedEquities declared a special dividend of $0.21 per share of MedEquities common stock (the “Pre-Closing Dividend”) payable to the holders of record of MedEquities common stock as of the trading day immediately prior to the closing date of the Merger, which dividend was payable following the effective time of the Merger together with the cash consideration under the Merger Agreement. For additional information see Note 3 – Properties. Consolidation Omega’s consolidated financial statements include the accounts of (i) Omega, (ii) Omega OP, (iii) all direct and indirect wholly owned subsidiaries of Omega and (iv) other entities in which Omega or Omega OP has a majority voting interest and control. 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.

SUMMARY OF SIGNIFICANT ACCOUNTI

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	12 Months Ended

Basis of Presentation and 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. 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 The Company is subject to certain risks and uncertainties affecting the healthcare industry as a result of healthcare legislation and growing 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. Business Combinations We record the purchase of properties to net tangible and identified intangible assets acquired and liabilities assumed at fair value. Transaction costs are expensed as incurred as part of a business combination. In making estimates of fair value for purposes of recording the purchase, 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. We also consider information obtained about each property as a result of our pre-acquisition due diligence, marketing and leasing activities as well as other critical valuation metrics such as current capitalization rates and discount rates used to estimate the fair value of the tangible and intangible assets acquired (Level 3). When liabilities are assumed as part of a transaction, we consider information obtained about the liabilities and use similar valuation metrics (Level 3). In some instances when debt is assumed and an identifiable active market for similar debt is present, we use market interest rates for similar debt to estimate the fair value of the debt assumed (Level 2). The Company determines fair value 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 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. ● Goodwill represents the purchase price in excess of the fair value of assets acquired and liabilities assumed. Goodwill is not amortized. ​ Asset Acquisitions For asset acquisitions, assets acquired and liabilities assumed are recognized by allocating the cost of the acquisition, including transaction costs, to the individual assets acquired and liabilities assumed on a relative fair value basis. The fair value of the assets acquired and liabilities assumed in an asset acquisition are determined in a consistent manner with the immediately preceding “Business Combinations” section. ​ Variable Interest Entities 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 variable interest entities (“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, 2019, we have not consolidated any VIEs, as we do not have the power to direct the activities of any VIEs that most significantly impact their economic performance and we do not have the obligation to absorb losses or receive benefits of the VIEs that could be significant to the entities. Real Estate Investments and Depreciation The costs of significant improvements, renovations and replacements, including interest are capitalized. 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 charged to operations 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 Lease Accounting In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 Leases (Topic 842): Codification Improvements to Topic 842, Leases Leases (Topic 842): Targeted Improvements Leases (Topic 842): Narrow-Scope Improvements for Lessors Lessor Accounting Topic 842 requires lessors to account for leases using an approach that is substantially equivalent to the previous guidance for sales type leases, direct financing leases and operating leases. At the inception of the lease and over its term, we evaluate each lease to determine the proper lease classification. Certain of these leases provide our operators the contractual right to use and economically benefit from all of the physical space specified in the lease, therefore we have determined that they should be evaluated as lease arrangements. As a lessor, our leased real estate properties are leased under provisions of single or master leases with initial terms typically ranging from 5 to 15 years, plus renewal options. As of December 31, 2019, we have determined that all but two of our leases should be accounted for as operating leases. Two leases are accounted for as direct financing leases. Under the terms of the leases, the lessee is responsible for all maintenance, repairs, taxes and insurance on the leased properties. For leases accounted for as operating leases, we retain ownership of the asset and record depreciation expense, see “Business Combinations” and “Real Estate Investments and Depreciation” above for additional information regarding our investment in real estate leased under operating lease agreements. We also record lease revenue based on the contractual terms of the operating lease agreement which often includes annual rent escalators, see “Revenue Recognition” below for further discussion regarding the recordation of revenue on our operating leases. 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. Certain direct financing leases include annual rent escalators; see “Revenue Recognition” below for further discussion regarding the recording of interest income on our direct financing leases. As of December 31, 2019 and 2018, we have no unamortized direct costs related to originating our direct financing leases recorded on our Consolidated Balance Sheets. Lessee Accounting At the inception of the lease and over its term, we evaluate each lease to determine the proper lease classification. Certain of these leases provide us the contractual right to use and economically benefit from all of the space specified in the lease. Therefore, we have determined that they should be evaluated as lease arrangements. As a lessee, the Company is party to ground and/or facility leases which are classified as operating leases. Substantially all of our operating leases contain provisions for specified annual increases over the rents of the prior year and are generally computed in one of three methods depending on the specific provisions of each lease as follows: (i) a specific annual increase over the prior year’s rent, generally between 1.0% and 3.0%; (ii) an increase based on the change in pre-determined formulas from year to year (e.g., increases in the Consumer Price Index); or (iii) specific dollar increases over prior years. The initial terms of our ground leases range between 10 years and 100 years. Our office leases have initial terms of approximately 10 years. 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 right-of-use assets and lease liabilities. The discount rate utilized in forming the basis of our right of use assets and lease liabilities approximates our cost of debt. We have not recognized a right of use asset and/or lease liability for leases with terms of 12 months or less and without an option to purchase the underlying asset. On a monthly basis, we remeasure 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. 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. As a lessee, certain of our operating leases contain non-lease components, such as our proportionate share of common area expenses. We have determined that all of our operating leases qualify for the practical expedient 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. We apply Topic 842 to the combined component. Lease expense derived from our operating leases is recorded in general and administrative in our Consolidated Statements of Operations. In-Place Leases In-place lease assets and liabilities result when we assume a lease as part of a facility purchase 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. Real Estate Investment Impairment Management evaluates our real estate investments 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 are probability-weighted based on management’s best estimates as of the date of evaluation. Provisions for 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 consider 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 the Company’s assets in a future period that could be material to the Company’s results of operations. For the years ended December 31, 2019, 2018 and 2017, we recognized impairment on real estate properties of $45.3 million, $29.8 million and $99.1 million, respectively. Allowance for Losses on Mortgages, Other Investments and Direct Financing Leases The allowances for losses on mortgage notes receivable, other investments and direct financing leases (collectively, our “loans”) are maintained at a level believed adequate to absorb potential losses. The determination of the allowances is based on a quarterly evaluation of these loans, including general economic conditions and estimated collectability of loan payments. We evaluate the collectability of our loans receivable based on a combination of factors, including, but not limited to, delinquency status, financial strength of the borrower and guarantors and the value of the underlying collateral. If such factors indicate that there is greater risk of loan charge-offs, additional allowances or placement on non-accrual status may be required. A loan is 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. Consistent with this definition, all loans on non-accrual status may be deemed impaired. To the extent circumstances improve and the risk of collectability is diminished, we will return these loans to full accrual status. When management identifies potential loan impairment indicators, the loan is written down to the present value of the expected future cash flows. In cases where expected future cash flows are not readily determinable, the loan is written down to the fair value of the underlying collateral. We may base our valuation on a loan’s observable market price, if any, or the fair value of collateral, net of sales costs, if the repayment of the loan is expected to be provided solely by the sale of the collateral. We account for impaired loans and direct financing leases using (a) the cost-recovery method, and/or (b) the cash basis method. We generally utilize the cost-recovery method for impaired loans or direct financing leases for which impairment reserves were recorded. We utilize the cash basis method for impaired loans or direct financing leases for which no impairment reserves were recorded because the net present value of the discounted cash flows expected under the loan or direct financing lease and/or the underlying collateral supporting the loan or direct financing lease were equal to or exceeded the book value of the loans or direct financing leases. Under the cost-recovery method, we apply cash received against the outstanding loan balance or direct financing lease 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. As of December 31, 2019 and 2018, we had $5.1 million and $108.1 million, respectively, of reserves on our loans. 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. The accounting policies for the unconsolidated joint ventures are the same as those of the Company. 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 loss on our investments in unconsolidated joint ventures was recognized during the years ended December 31, 2019, 2018, or 2017. 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. 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. ​ 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. We assess the probability of collecting substantially all payments under our leases based on several factors, including, among other things, payment history of the lessee, the financial strength of the lessee and any guarantors, historical operations and operating trends and current and future economic conditions and expectations of performance. 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 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. 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. On a quarterly basis, and more frequently as appropriate, we review our contractual interest receivables, effective yield interest receivables and direct financing lease receivables to determine their collectability. The determination of collectability of these assets requires significant judgment and is affected by several factors relating to the credit quality of our operators that we regularly monitor, including (i) payment history, (ii) the age of the contractual receivables, (iii) the current economic conditions and reimbursement environment, (iv) the ability of the operator to perform under the terms of their lease and/or contractual loan agreements and (v) the value of the underlying collateral of the agreement, if any. For a loan recognized on an effective yield basis or a direct financing lease, we generally provide an allowance for effective interest or income from direct financing leases when certain conditions or indicators of adverse collectability are present. If these accounts receivable balances are subsequently deemed uncollectible, the receivable and allowance for doubtful account balance are written off. A summary of our net receivables and inducements by type is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ ​ 2019 2018 ​ ​ (in thousands) ​ Contractual receivables ​ $ 27,122 ​ $ 34,901 ​ Allowance ​ — ​ (1,075) ​ Contractual receivables – net ​ $ 27,122 ​ $ 33,826 ​ ​ ​ ​ ​ ​ ​ ​ ​ Effective yield interest receivables ​ $ 12,914 ​ $ 12,741 ​ Straight-line rent receivables ​ 275,549 ​ 251,166 ​ Lease inducements ​ 92,628 ​ 49,644 ​ Other receivables and lease inducements ​ $ 381,091 ​ $ 313,551 ​ ​ In 2019, we wrote-off approximately $11.1 million of contractual receivables, straight-line rent receivables and lease inducements to rental income, of which $9.9 million resulted from placing five operators on a cash-basis due to changes in our evaluation of the collectability of future rent payments due under the respective lease agreements. The remaining $1.2 million write-off of straight-line rent receivables to rental income resulted from transitioning a facility to another existing operator. In 2019, we paid certain operators $50.8 million which were accounted for as lease inducements that are amortized as a reduction to rental income over the remaining term of the lease. Of the $50.8 million, $15.0 million was paid to Genesis Healthcare, Inc. and $35.8 million was paid to seven other existing operators. In 2018, we paid an existing operator approximately $50 million in exchange for a reduction of such operator’s participation in an in-the-money purchase option. As a result, we recorded an approximate $28 million lease inducement that is being amortized as a reduction to rental income over the remaining term of the lease. The remaining $22 million was recorded as a reduction to our initial contingent liability. Our initial contingent liability was recorded in our merger with Aviv REIT, Inc. and included in accrued expenses and other liabilities on our Consolidated Balance Sheets. In 2018, we wrote-off approximately $11.5 million of straight-line rent receivables and contractual receivables to provision for uncollectible accounts, as a result of facility transitions and placing an operator on a cash basis. The provision for uncollectible accounts was offset by a recovery of approximately $4.8 million. In 2017, we recorded a provision for uncollectible accounts of approximately $9.3 million related to contractual and straight-line rent receivables for one of our operators and approximately $4.1 million of provision for uncollectible accounts, net of recoveries related to contractual and straight-line receivables of other operators and/or facilities that we intend to exit or transition. Goodwill Impairment We assess goodwill for potential impairment during the fourth quarter of each fiscal year, or during the year 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 on an interim basis, 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 is, a likelihood of more than 50 percent) that the fair value of the reporting unit is less than its carrying amount. On an annual basis during the fourth quarter of each fiscal year, or on an interim basis if we conclude it is more likely than not that the fair value of the reporting unit is less than its carrying value, we perform a two-step goodwill impairment test to identify potential impairment and measure the amount of impairment we will recognize, if any. The goodwill is not deductible for tax purposes. ​ In the first step of the two-step goodwill impairment test (“Step 1”), we compare the fair value of the reporting unit to its net book value, including goodwill. As the Company has only one reporting unit,

(2) The acquisition was accounted for as a business combination. The Company estimated the fair value of the real estate investments acquired on the acquisition date based on certain valuation analyses that have yet to be finalized, and accordingly, the real estate investments acquired, as detailed, are subject to adjustment once the analysis is completed which will be completed within the allowable measurement period. The other acquisitions were accounted for as asset acquisitions. (3) Acquired via a deed-in-lieu of foreclosure. ​ During 2019, we acquired one parcel of land (not reflected in the table above) for approximately $10.7 million with the intent of building a new facility for an existing operator. ​ Encore Portfolio Acquisition ​ On October 31, 2019, we completed the $757 million portfolio acquisition of 60 facilities (the “Encore Portfolio”). Consideration consisted of approximately $369 million of cash and the assumption of approximately $389 million in mortgage loans guaranteed by HUD.

In accordance with the Merger Agreement, each share of MedEquities common stock issued and outstanding immediately prior thereto was converted into the right to receive (i) 0.235 of a share of Omega common stock plus the right to receive cash in lieu of any fractional shares of Omega common stock, and (ii) an amount in cash equal to $2.00 (the “Cash Consideration”). In connection with the MedEquities Merger, we issued approximately 7.5 million shares of Omega common stock and paid approximately $63.7 million of cash consideration to former MedEquities stockholders. We borrowed approximately $350 million under our existing senior unsecured revolving credit facility to fund the cash consideration and the repayment of MedEquities’ previously outstanding debt. As a result of the MedEquities Merger, we acquired 33 facilities subject to operating leases, four mortgages, three other investments and an investment in an ​ The following table highlights the preliminary fair value of the assets acquired and liabilities assumed on May 17, 2019: ​ ​ ​ ​ ​ ​ (in thousands) Fair value of net assets acquired: ​ ​ ​ Real estate investments (3) ​ $ 421,600 Mortgage notes receivable (see Note 5) ​ 108,097 Other investments ​ 19,192 Investment in unconsolidated joint venture ​ 73,834 Cash ​ 4,067 Contractual receivables ​ 1,461 Other assets (1) (3) ​ 32,819 Total investments ​ ​ 661,070 Debt ​ ​ (285,100) Accrued expenses and other liabilities (2)(3) ​ ​ (30,421) Fair value of net assets acquired ​ $ 345,549 (1) (2) (3) With the exception of real estate investments, above market lease assets and below market lease liabilities, the fair value estimates above are final. ​ The MedEquities facilities acquired in 2019 are included in our results of operations from the date of acquisition.

(4) All of these acquisitions were accounted for as asset acquisitions. ​ During 2018, we acquired two parcels of land (not reflected in the table above) for approximately $3.5 million with the intent of building new facilities for our existing operators. During 2018, we transitioned 21 SNFs and one ALF subject to direct financing leases (not reflected in the table above) with a net carrying value of approximately $184.5 million from an existing operator to five other existing operators subject to single or master operating leases with an initial annual cash yield of approximately 9%. We recorded approximately $184.5 million of real estate investments consisting of land ($11.2 million), building and site improvements ($159.1 million) and furniture and fixtures ($14.2 million) in partial satisfaction of the direct financing leases. In connection with these transitions, we provided the new operators with working capital loans with a maximum borrowing capacity of $45.7 million, commitments to fund capital improvements up to $10.6 million and indemnities with a maximum funding of $7.4 million. Claims against these indemnities must occur within 18 months to 36 months of the transition date. These indemnities were provided to the new operators upon transition and would be utilized in the event that the prior operator does not perform under their transition agreements. As of December 31, 2019, we have not and we do not expect to fund a material amount under these indemnity agreements. 2017 Acquisitions and Other ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Number of ​ ​ ​ Total ​ ​ ​ ​ Building & Site ​ Furniture ​ Initial ​ ​ Facilities Country/ Investment (4) Land Improvements & Equipment Annual ​ Period ​ SNF ​ ALF/ILF ​ State ​ (in millions) ​ Cash Yield (2) ​ Q1 — 1 VA ​ $ 7.6 ​ $ 0.5 $ 6.8 $ 0.3 7.50 % Q2 1 — NC ​ 8.6 ​ 0.7 ​ 7.3 ​ 0.6 9.50 % Q2 — 18 UK ​ 124.2 (1) 34.1 ​ 85.1 ​ 5.0 8.50 % Q3 — 1 TX ​ 2.3 ​ 0.7 ​ 1.5 ​ 0.1 9.25 % Q3 15 — IN ​ 211.0 ​ 18.0 ​ 180.2 ​ 12.8 9.50 % Q3 9 — TX ​ 19.0 (3) 1.7 ​ 15.5 ​ 1.8 18.60 % Q4 6 — TX ​ 40.0 ​ 1.0 ​ 35.1 ​ 3.9 9.25 % Total 31 20 ​ $ 412.7 $ 56.7 $ 331.5 $ 24.5 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ (1) We recorded a non-cash deferred tax liability and acquisition costs of approximately $8.2 million and $1.2 million, respectively, in connection with this acquisition.

(3) In July 2017, we transitioned nine SNFs formerly subject to a direct financing lease to another operator. As a result of terminating the direct financing lease, we wrote down the facilities to our original cost basis and recorded an impairment on the direct financing lease of approximately $1.8 million. See Note 4 – Direct Financing Leases for additional information. (4) All of these acquisitions were accounted for as asset acquisitions. ​ During 2017, we acquired three parcels of land (not reflected in the table above) for approximately $6.7 million with the intent of building new facilities for existing operators. Asset Sales, Impairments and Other During the fourth quarter of 2019, we sold 11 facilities (three previously held for sale at September 30, 2019) for approximately $33.3 million in net cash proceeds recognizing a gain on sale of approximately $2.9 million. In addition, we recorded impairments on real estate properties of approximately $35.7 million on 17 facilities (five were subsequently reclassified to held for sale). In 2019, we sold 34 facilities (one was previously held for sale at December 31, 2018) for approximately $219.3 million in net cash proceeds recognizing a net gain of approximately $55.7 million. In addition, we recorded impairments on real estate properties of approximately $45.3 million on 23 facilities. After considering the impairments recorded and facilities sold during the year, the total net recorded investment in these properties was approximately $23.4 million as of December 31, 2019, with approximately $4.6 million related to properties classified as held for sale. Our impairments were offset by approximately $3.7 million of insurance proceeds received related to two facilities that were previously destroyed. ​ In 2018, we sold 78 facilities (22 previously held for sale at December 31, 2017) subject to operating leases for approximately $309.6 million in net proceeds recognizing a gain on sale of approximately $24.8 million. In addition, we recorded impairments on real estate properties of approximately $35.0 million on 35 facilities. Our impairments were offset by $5.2 million of insurance proceeds received related to a facility destroyed in November 2017. After considering the impairments recorded and facilities sold during the year, the total net recorded investment in these properties was approximately $14.8 million as of December 31, 2018, with approximately $1.0 million related to properties classified as held for sale. ​ Of the 78 facilities sold during 2018, we sold 12 SNFs on June 1, 2018 secured by HUD mortgages to subsidiaries of an existing operator. The Company sold the 12 SNF facilities with carrying values of approximately $62 million for approximately $78 million which consisted of $25 million of cash consideration and their assumption of approximately $53 million of our HUD mortgages. See Note 13 – Borrowing Arrangements for additional details. Simultaneously, subsidiaries of the operator assumed our HUD restricted cash accounts, deposits and escrows. The Company recorded a gain on sale of approximately $11 million after approximately $5 million of closing and other transaction related costs. In connection with this sale, we provided a principal of an existing operator an unsecured loan of approximately $39.7 million. ​ In 2017, we sold 52 facilities (14 previously held for sale at December 31, 2016) subject to operating leases for approximately $257.8 million in net proceeds recognizing a gain on sale of approximately $53.9 million. In addition, we recorded impairments on real estate properties of approximately $99.1 million on 37 facilities including approximately $2.6 million of capitalized costs associated with the termination of construction projects with two of our operators. After considering the impairments recorded and facilities sold during the year, the total net recorded investment in these properties was approximately $125.1 million as of December 31, 2017. Of the 52 facilities sold in 2017, the sale of ten of these facilities did not initially qualify for sale accounting under the full accrual method. The ten SNFs with a carrying value of approximately $23.2 million were sold to a third-party for approximately $43.3 million, resulting in a total gain of approximately $17.5 million after $2.6 million of closing costs. In connection with this sale, we provided the buyer a $10.0 million loan. We recognized a net gain of approximately $7.5 million in 2017. Upon our adoption of ASU 2014-09 on January 1, 2018, we recognized $10.0 million of deferred gain related to this sale through opening equity on January 1, 2018. The 2019, 2018 and 2017 recorded impairments were primarily the result of decisions to exit certain non-strategic facilities and/or operators. We reduced the net book value of the impaired facilities to their estimated fair values or, with respect to the facilities reclassified to held for sale, to their estimated fair value less costs to sell. To estimate the fair value of the facilities, we utilized a market approach which considered binding sale agreements (a Level 1 input) and/or non-binding offers from unrelated third parties and/or broker quotes (a Level 3 inputs).

(“Ark Holding”) by 4 West Holdings Inc. At closing, we acquired 55 SNFs and 1 ALF operated by Ark Holding and leased the facilities back to Ark Holding, now known as New Ark Investment Inc. (“New Ark” which does business as “Orianna Health Systems” and is herein referred to as “Orianna”), pursuant to four 50-year In addition to our direct financing leases with Orianna, we previously leased three facilities to Orianna under a master lease which was to expire in 2026. The remaining three facility lease was accounted for as an operating lease. Our recorded investment in the three facilities subject to this operating lease was $30.5 million as of December 31, 2018. On October 31, 2018, Orianna rejected the operating lease and as a result we transitioned these three facilities to an existing operator during the first quarter of 2019. In 2017, we sold eight facilities subject to direct financing leases with Orianna in the Northwest region and the Southeast region of the U.S. with a carrying value of approximately $36.4 million for approximately $33.3 million to unrelated third parties. These facilities were subject to direct financing leases with Orianna in the Northwest region and the Southeast region. We recorded approximately $3.3 million of impairment related to these sales. In addition, we transitioned nine SNFs, representing all of the facilities subject to another direct financing lease with Orianna in the Texas region, to an existing operator of ours pursuant to an operating lease. In connection with this transaction, we recorded the real estate properties at our original cost basis of approximately $19.0 million, eliminated our investment in the Texas region direct financing lease and recorded an impairment of approximately $1.8 million. In conjunction with this transaction, we also amended our Orianna Southeast region master lease to reduce the outstanding balance by $19.3 million. As a result of the lease amendment in 2017, we recorded an impairment on our investment in direct financing lease of approximately $20.8 million in 2017. In the third quarter of 2017, we recorded an allowance for loss on direct financing leases of $172.2 million with Orianna covering 38 facilities in the Southeast region of the U.S. The amount of the allowance was determined based on the fair value of the facilities subject to the direct financing lease. To estimate the fair value of the underlying collateral, we utilized an income approach and Level 3 inputs. Our estimate of fair value assumed annual rents ranging between $32.0 million and $38.0 million, rental yields between 9% and 10%, current and projected operating performance of the facilities, coverage ratios and bed values. In March 2018, Orianna commenced voluntary Chapter 11 proceedings in the United States Bankruptcy Court for the Northern District of Texas, Dallas Division (the “Bankruptcy Court”). As described in Orianna’s filings with the Bankruptcy Court, we entered into a Restructuring Support Agreement (“RSA”) that was expected to form the basis for Orianna’s restructuring. The RSA provided for the recommencement, in April 2018, of partial rent payments at $1.0 million per month and established a specific timeline for the implementation of Orianna’s planned restructuring. The RSA provided for the transition of 23 facilities to new operators and the potential sale of the remaining 19 facilities subject to the plan of reorganization (the “Plan”), if approved by the Bankruptcy Court. To provide liquidity to Orianna during their Chapter 11 proceedings, we entered into a senior secured superpriority debtor-in-possession (“DIP”) credit agreement with Orianna for a revolving credit and term loan DIP financing of up to $30 million, which DIP financing was approved by the Bankruptcy Court on an interim basis on March 9, 2018 and on a final basis on May 14, 2018. On July 23, 2018, we notified Orianna that it was in default under the DIP credit agreement. On July 25, 2018, we terminated the RSA with its tenant, 4 West Holdings, and the sponsor of Orianna’s Plan. During the third quarter of 2018, we transitioned 22 facilities with a net carrying value of approximately $184.5 million from Orianna to five other existing operators with annual contractual rent of approximately $16.8 million. See Note 3 – Properties. In addition, during the second half of 2018, we sold Orianna’s headquarters and one SNF with a carrying value of approximately $5.5 million to unrelated third-parties for approximately $5.5 million. ​ During the fourth quarter of 2018, the Bankruptcy Court ruled that Orianna’s Plan, if confirmed, would allow Orianna to use the value of Orianna’s remaining facilities to pay the administrative costs of Orianna’s Chapter 11 cases and to pay certain other creditor claims, with the net amount of such value being paid to us. As a result, we recorded $27.2 million in additional allowance for loss to reduce the remaining investment in the direct financing lease covering the remaining 15 facilities located in the Southeast region of the U.S. As of December 31, 2018, our net investment in the Orianna direct financing lease was approximately $120.5 million, net of an allowance of $103.2 million. On January 11, 2019, pursuant to a Bankruptcy Court order, affiliates of Orianna purchased the remaining 15 SNFs subject to the direct financing lease with Orianna for $176 million of consideration, comprised of $146 million in cash received by Orianna and a $30.0 million seller note held by the Company. The $30.0 million note bears interest at 6% per annum and matures on January 11, 2026. Interest on the unpaid principal balance is due quarterly in arrears. Commencing on January 11, 2022, quarterly principal payments are due based on a 15-year amortization schedule on the then outstanding principal balance of the loan. On the same date, Orianna repaid the DIP financing, including all related interest. ​ On January 16, 2019, the Bankruptcy Court confirmed Orianna’s Plan, creating a Distribution Trust (the “Trust”) to distribute the proceeds from Orianna’s sale of the remaining 15 SNFs, as well as the Trust’s collections of Orianna’s accounts receivable portfolio. In January 2019, we reclassified our net investment in direct financing lease of $115.8 million from the Trust to other assets on our Consolidated Balance Sheet. For the period from January 16, 2019 through December 31, 2019, we received approximately $94 million from the Trust as a partial liquidation. ​ In March 2019, we received updated information from the Trust indicating diminished collectability of the accounts receivable owed to us. As a result, we recorded an additional $7.7 million allowance. As of December 31, 2019, our remaining receivable from the Trust is approximately $14 million. As of December 31, 2019, the Trust was comprised of approximately $14 million of cash.

Mortgage Notes Receivable [Abstract]
MORTGAGE NOTES RECEIVABLE	NOTE 5 - MORTGAGE NOTES RECEIVABLE As of December 31, 2019, mortgage notes receivable relate to nine fixed rate mortgages on 53 long-term care facilities. The mortgage notes are secured by first mortgage liens on the borrowers’ underlying real estate and personal property. The mortgage notes receivable relate to facilities located in eight states, operated by seven independent healthcare operating companies. We monitor compliance with mortgages and when necessary have initiated collection, foreclosure and other proceedings with respect to certain outstanding loans. The principal amounts outstanding of mortgage notes receivable, net of allowances, were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ ​ 2019 2018 ​ ​ (in thousands) ​ Mortgage note due 2027; interest at 10.39% ​ $ 112,500 ​ $ 112,500 ​ Mortgage notes due 2029; interest at 10.08% (1) ​ 526,520 ​ 537,515 ​ Other mortgage notes outstanding (2) ​ 139,448 ​ 65,748 ​ Mortgage notes receivable, gross ​ 778,468 ​ 715,763 ​ Allowance for loss on mortgage notes receivable (3) ​ (4,905) ​ (4,905) ​ Total mortgages — net ​ $ 773,563 ​ $ 710,858 ​ (1) Approximates the weighted average interest rate on 36 facilities. Three notes totaling approximately $36.2 million are construction mortgages with maturities through 2021 . The remaining loan balance matures in 2029 . (2) Other mortgage notes outstanding have a weighted average interest rate of 9.45% per annum and maturity dates through 2028 . (3) The allowance for loss on mortgage notes receivable relates to one mortgage with an operator. The carrying value and fair value of the mortgage note receivable is approximately $1.5 million at December 31, 2019 and December 31, 2018. ​ $112.5 On January 17, 2014, we entered into a $112.5 million first mortgage loan with an existing operator. The loan is secured by seven SNFs and two ALFs located in Pennsylvania and Ohio, respectively. 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. $526.5 On June 30, 2014, we entered into a mortgage loan agreement with Ciena Healthcare (“Ciena”) to refinance/consolidate $117 million in existing mortgages with maturity dates ranging from 2021 to 2023 on 17 facilities into one mortgage and simultaneously provide mortgage financing for an additional 14 facilities. The $415 million amortizing mortgage (the “Master Mortgage”) matures in 2029 and is secured by 25 facilities. The Master Mortgage note bore an initial interest rate of 9.0% per annum which increases by 0.225% per annum. As of December 31, 2019, the outstanding principal balance of the Master Mortgage note is approximately $380.8 million and the interest rate is 10.13% per annum. Subsequent to June 30, 2014, the Company amended its Master Mortgage with Ciena to provide for additional borrowings in the form of incremental facility mortgages, construction and/or improvement mortgages with maturities through 2029 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, 2019, the outstanding principal balance of these mortgage notes are approximately $101.7 million. In June 2018, we amended the Master Mortgage with Ciena to provide an additional $44.7 million mortgage note related to five SNFs located in Michigan. The mortgage note matures on June 30, 2029 and bears an initial annual interest rate of 9.5% which increases each year by 0.225%. As of December 31, 2019, the outstanding principal balance of this mortgage note is approximately $44.1 million. Additionally, the Company committed to fund an additional $9.6 million to Ciena if certain performance metrics are achieved by the portfolio. The mortgage notes with Ciena are cross-defaulted and cross-collateralized with our existing master lease and other investment notes with the operator.

(2) Other investment notes have a weighted average interest rate of 8.38% and maturity dates through 2029 . ​ Other investment note due 2019 On September 28, 2018, we provided a $131.3 million secured term loan to an unrelated third party. The loan was secured by a collateral assignment of mortgages covering seven SNFs, three independent living facilities and one ALF. The loan bore interest at 9.35% per annum and matured on May 31, 2019. The loan required monthly interest payments with the principal balance due at maturity. The borrower used the proceeds to repay existing indebtedness and pay a one-time distribution to its equity holders. In connection with this loan we incurred approximately $0.4 million of origination costs which are deferred and recognized over the term of the loan. On May 31, 2019, we acquired these facilities located in Pennsylvania (9) and Virginia (2) via deed-in-lieu of foreclosure and subsequently leased the facilities to an existing operator of the Company. Other investment note due 2020-2025 ​ On September 30, 2016, we acquired and amended a term loan with a fair value of approximately $37.0 million with Agemo Holdings LLC (“Agemo” an entity formed in May 2018 to silo our leases and loans formerly held by Signature Healthcare). A $5.0 million tranche of the term loan that bore interest at 13% per annum was repaid in August 2017. The remaining $32.0 million tranche of the term loan bears interest at 9% per annum and currently matures on December 31, 2024. The $32.0 million term loan (and the $25.0 million working capital loan discussed below) is secured by a security interest in the collateral of Agemo. ​ On May 7, 2018, the Company provided Agemo a $25.0 million secured working capital loan bearing interest at 7% per annum that matures on April 30, 2025. The proceeds of the working capital loan were used to pay operating expenses, settlement payments, fees, taxes and other costs approved by the Company. As of December 31, 2019, approximately $25.0 million is outstanding on this working capital loan. Additionally, on May 7, 2018, the Company also provided principals of Agemo a one year unsecured $2.8 million loan. The proceeds were used to pay down the Company’s contractual receivables outstanding. This loan was repaid in 2019. On November 5, 2019, the Company provided Agemo a $1.7 million term loan bearing interest at a fixed rate of 9% per annum and matures on March 31, 2020. As of December 31, 2019, $1.7 million is outstanding on this term loan. Our total loans outstanding with Agemo at December 31, 2019 approximate $58.7 million. ​ Other investment notes due 2021 On July 29, 2016, we provided Genesis HealthCare, Inc. (“Genesis”) a $48.0 million secured term loan bearing interest at LIBOR with a floor of 1% plus 13% that was initially scheduled to mature on July 29, 2020. On May 9, 2019, we extended the maturity of this loan to November 30, 2021. This term loan (and the 2018 term loan discussed below) is secured by a perfected first priority lien on and security interest in certain collateral of Genesis. The term loan required monthly principal payments of $0.25 million through July 2019, and $0.5 million from August 2019 through maturity. In addition, a portion of the monthly interest accrued to the outstanding principal balance of the loan. In November 2017, we provided Genesis forbearance through February 2018. The forbearance allowed for the deferral of principal payments and permitted Genesis to accrue all interest due to the outstanding principal balance of the loan. On March 6, 2018, we amended certain terms of the 2016 term loan to Genesis. Commencing February 22, 2018, the 2016 term loan bears interest at a fixed rate of 14% per annum, of which 9% per annum shall be paid-in-kind. Additionally, the amended term loan does not require monthly payments of principal. All principal and accrued and unpaid interest will be due at maturity on November 30, 2021. As of December 31, 2019, approximately $59.6 million is outstanding on this term loan. ​ Also on March 6, 2018, we provided Genesis an additional $16.0 million secured term loan bearing interest at a fixed rate of 10% per annum, of which 5% per annum is paid-in-kind, that was initially scheduled to mature on July 29, 2020. On May 9, 2019, we extended the maturity of this loan to November 30, 2021. As of December 31, 2019, approximately $17.5 million is outstanding on this term loan. ​ ​ Other investment note due 2023 ​ On June 30, 2015, we entered into a $50.0 million secured revolving credit facility with subsidiaries of an existing operator. The note bears interest at approximately 6.66% per annum and matures in 2023. As of December 31, 2019, $50.0 million has been drawn and remains outstanding. ​ On May 17, 2017, we entered into a separate secured $15.0 million revolving credit facility with subsidiaries of an existing operator. The note bears interest at 9.5% per annum and matures in 2023. As of December 31, 2019, $15.0 million has been drawn and remains outstanding. ​ Other investment note due 2023 ​ On February 26, 2016, we acquired and funded a $50.0 million mezzanine loan at a discount of approximately $0.75 million. In May 2018, the Company amended the mezzanine loan with the borrower which is secured by an equity interest in subsidiaries of the borrower. As part of the refinancing, the Company increased the mezzanine loan by $10.0 million, extended the maturity date to May 31, 2023 and fixed the interest rate at 12% per annum. The mezzanine loan requires semi-annual principal payments of $2.5 million commencing December 31, 2018. As of December 31, 2019, our total other investments outstanding with this borrower was approximately $52.2 million. In connection with the amendment, the Company recognized fees of approximately $1.1 million of which $0.5 million was paid at closing with the remainder due at maturity. The discount and loan fees are deferred and are being recognized on an effective basis over the term of the loan.

See Note 4 – Direct Financing Leases regarding our relationship with Orianna, Note 6 – Other Investments regarding the terms of the other investments and Note 20 – Commitments and Contingencies regarding our commitment to provide capital expenditure funding to our operators which includes Agemo. In May 2018, we reached an out-of-court restructuring agreement with Agemo that provided for the deferral of rent, the extension of the maturity of our lease and loans, and a working capital loan. If Agemo’s operations deteriorate any further and they are unable to meet their contractual obligations to us, we may be required to account for rental income from them on a cash basis and reserve approximately $71.2 million of contractual receivables, straight-line rent receivables and lease inducements.

(the “Lakeway Partnership”), a joint venture that owns the Lakeway Hospital. On the merger date, the Company’s ownership interest in the Lakeway Partnership had a fair value of approximately $73.8 million. Our investment in the Lakeway Partnership consists primarily of real estate. We estimated the fair value of the underlying real estate considering the lessees’ purchase option (Level 1) which is discussed in more detail below, third-party appraisals and discounted cash flows associated with the ground lease (Level 3). Our initial basis difference of approximately $69.9 million is being amortized on a straight-line basis over 40 years to income (loss) from unconsolidated joint ventures in the accompanying Consolidated Statements of Operations. The Company also acquired a first mortgage lien issued to Lakeway Partnership 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.

The HUD loans have remaining terms ranging from 27 to 32 years and an average remaining term of 31 years with fixed interest rates ranging from 2.82% to 3.24%. 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. All HUD loans are subject to the regulatory agreements that require escrow reserve funds to be deposited with the loan servicer for mortgage insurance premiums, property taxes, debt service and capital replacement expenditures. As of December 31, 2019, the Company has total escrow reserves of $25.0 million with the loan servicer that is reported within other assets on the Consolidated Balance Sheets. See Note 3 – Properties. HUD Mortgage Disposition On June 1, 2018, subsidiaries of an existing operator assumed approximately $53 million of our indebtedness guaranteed by HUD that secured 12 separate facilities located in Arkansas. In connection with our disposition of the mortgages, we wrote-off approximately $0.6 million of unamortized deferred costs that are recorded in Gain on assets sold – net on our Consolidated Statements of Operations. These fixed rate mortgages had a weighted average interest rate of approximately 3.06% per annum and matured in July 2044 Unsecured Borrowings 2017 Omega Credit Facilities On May 25, 2017, Omega entered into a credit agreement (the “2017 Omega Credit Agreement”) providing us with 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 “Revolving Credit Facility”), a $425 million senior unsecured U.S. Dollar term loan facility (the “U.S. Term Loan Facility”), and a £100 million senior unsecured British Pound Sterling term loan facility (the “Sterling Term Loan Facility” and, together with the Revolving Credit Facility and the U.S. Term Loan Facility, collectively, the “2017 Omega Credit Facilities”). The 2017 Omega Credit Agreement contains an accordion feature permitting us, subject to compliance with customary conditions, to increase the maximum aggregate commitments under the 2017 Omega Credit Facilities to $2.5 billion. The 2017 Omega Credit Facilities replaced the previous $1.25 billion senior unsecured 2014 revolving credit facility, the previous $200 million Tranche A-1 senior unsecured term loan facility, and the previous $350 million Tranche A-3 senior unsecured incremental term loan facility established under our 2014 credit agreement, which has been terminated (the “2014 Omega Credit Agreement”). We had previously repaid and terminated the $200 million Tranche A-2 senior unsecured term loan facility established under the 2014 Omega Credit Agreement, with proceeds from our $550 million and $150 million unsecured senior notes issued in April 2017. The Revolving Credit Facility bears 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 Revolving Credit Facility matures on May 25, 2021, subject to an option by us to extend such maturity date for two, six month periods. The 2017 Omega Credit Agreement provides for the Revolving Credit Facility to be drawn in Euros, British Pounds Sterling, Canadian Dollars (collectively, “Alternative Currencies”) or U.S. Dollars, with a $900 million tranche available in U.S. Dollars and a $350 million tranche available in U.S. Dollars or Alternative Currencies. For purposes of the 2017 Omega Credit Facilities, 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 2017 Omega Credit Agreement for amounts offered in any other non-London interbank offered rate quoted currency, as applicable. The U.S. Term Loan Facility and the Sterling Term Loan Facility bear 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. The U.S. Term Loan Facility and the Sterling Term We recorded a non-cash charge of approximately $5.5 million in 2017 relating to the write-off of deferred financing costs associated with the termination of the 2014 Omega Credit Agreement. 2017 Omega OP Term Loan Facility 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 Omega OP Term Loan Facility”). The 2017 Omega OP Term Loan Facility bears 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. The 2017 Omega OP Term Loan Facility matures on May 25, 2022. Omega OP’s obligations in connection with the 2017 Omega OP Term Loan Facility are not currently guaranteed, but will be jointly and severally guaranteed by any domestic subsidiary of Omega OP that provides a guaranty of any unsecured indebtedness of Omega or Omega OP for borrowed money evidenced by bonds, debentures, notes or other similar instruments in an amount of at least $50 million individually or in the aggregate. In connection with the MedEquities Merger on May 17, 2019, we assumed various interest rate swap contracts. 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 convert $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. The 2017 Omega OP Credit Agreement will be unhedged for the period after February 10, 2022 through its maturity on May 25, 2022. In September 2019, we used $25.0 million of proceeds from the senior notes issuance to repay borrowings under the 2017 Omega OP Term Loan Facility. At December 31, 2019, we had $75.0 million in outstanding borrowings under this facility. 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 bears 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. The Amended 2015 Term Loan Facility continues to mature on December 16, 2022. The Amended 2015 Credit Agreement permits us, subject to compliance with customary conditions, to add one or more incremental tranches to the Amended 2015 Term Loan Facility in an aggregate principal amount not exceeding $150 million. Omega’s obligations under the 2017 Omega Credit Facilities and the Amended 2015 Term Loan Facility are jointly and severally guaranteed by Omega OP and any domestic subsidiary of Omega that provides a guaranty of any unsecured indebtedness of Omega for borrowed money evidenced by bonds, debentures, notes or other similar instruments in an amount of at least $50 million individually or in the aggregate. 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 3.8005% 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 began on December 30, 2016 and mature on December 15, 2022. The interest rate for the Amended 2015 Term Loan Facility was not hedged for the portion of the term prior to December 30, 2016. $700 4.375% On July 12, 2016, we issued $700 million aggregate principal amount of our 4.375% Senior Notes due 2023 (the “2023 Notes”).

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. ​ ● Direct financing leases: The fair value of the investments in direct financing leases, excluding those related to Orianna, are estimated using a discounted cash flow analysis, using interest rates being offered for similar leases to borrowers with similar credit ratings (Level 3). For the Orianna direct financing lease as of December 31, 2018, the Company estimated the fair value of its investment based on the expected liquidating payments from the Trust as further described in Note 4 – Direct Financing Leases (Level 3). ● Mortgage notes receivable: The fair value of the mortgage notes receivables are estimated using a discounted cash flow analysis, using interest rates being offered for similar loans to borrowers with similar credit ratings (Level 3). ● Other investments: Other investments 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 line of credit, secured borrowing and term loans: The fair value of our borrowings under variable rate agreements are estimated using a present value technique based on expected cash flows discounted using the current market rates (Level 3). ● Senior notes and subordinated debt: The fair value of our borrowings under fixed rate agreements are estimated using a present value technique based on inputs from trading activity provided by a third party (Level 2). ● 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 15 – 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. In order to qualify as a REIT, in addition to other requirements, we must: (i) distribute dividends (other than capital gain dividends) to our stockholders in an amount at least equal to (A) the sum of (a) 90% of our “REIT taxable income” (computed without regard to the dividends paid deduction and our net capital gain), and (b) 90% of the net income (after tax), if any, from foreclosure property, minus (B) the sum of certain items of non-cash income on an annual basis, (ii) ensure that at least 75% and 95%, respectively, of our gross income is generated from qualifying sources that are described in the REIT tax law, (iii) ensure that at least 75% of our assets consist of qualifying assets, such as real property, mortgages, and other qualifying assets described in the REIT tax law, (iv) ensure that we do not own greater than 10% in voting power or value of securities of any one issuer, (v) ensure that we do not own either debt or equity securities of another company that are in excess of 5% of our total assets and (vi) ensure that no more than 20% of our assets are invested in one or more taxable REIT subsidiaries (and with respect to taxable years beginning before January 1, 2018, no more than 25%). In addition to the above requirements, the REIT rules require that no less than 100 stockholders own shares or an interest in the REIT and that five or fewer individuals do not own (directly or indirectly) more than 50% of the shares or proportionate interest in the REIT during the last half of any taxable year. If we fail to meet the above or any other 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. So long as we qualify 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 2019, 2018, and 2017, we distributed dividends in excess of our taxable income. The definition of foreclosure property includes any “qualified health care property,” as defined in Code Section 856(e)(6) acquired by us as the result of the termination or expiration of a lease of such property. We have from time to time operated qualified healthcare facilities acquired in this manner for up to two years (or longer if an extension was granted). Properties that we had taken back in a foreclosure or bankruptcy and operated for our own account were treated as foreclosure properties for income tax purposes, pursuant to Code Section 856(e). Gross income from foreclosure properties was classified as “good income” for purposes of the annual REIT income tests upon making the election on the tax return. Once made, the income was classified as “good” for a period of three years, or until the properties were no longer operated for our own account. In all cases of foreclosure property, we utilized an independent contractor to conduct day-to-day operations to maintain REIT status. In certain cases, we operated these facilities through a taxable REIT subsidiary. As a result of the foregoing, we do not believe that our past participation in the operation of nursing homes increased the risk that we would fail to qualify as a REIT. We currently own stock in an entity that has elected to be taxed as a REIT. This subsidiary entity is required to individually satisfy all of the rules for qualification as a REIT qualification. Subject to the limitation under the REIT asset test rules, we are permitted to own up to 100% of the stock of one or more taxable REIT subsidiaries (“TRSs”). We have elected for five of our active subsidiaries to be treated as TRSs. Three of our TRSs are domestic and are subject to federal, state and local income taxes at the applicable corporate rates and the other two are subject to foreign income taxes. As of December 31, 2019, one of our TRSs that is subject to federal, state and local income taxes at the applicable corporate rates had a net operating loss carry-forward of approximately $5.7 million. Up to 100% of the net operating loss carry-forwards arising in taxable years ending prior to January 1, 2018, may be used to reduce taxable income for any taxable year during the eligible carry-forward period. The net operating loss carry-forward arising in tax years ending subsequent to December 31, 2018, may be used to reduce only 80% of taxable income for any taxable year during the eligible carry-forward period. Our net operating loss carry-forward is fully reserved as of December 31, 2019, with a valuation allowance due to uncertainties regarding realization. Under current law, our net operating loss carryforwards generated up through December 31, 2017 may be carried forward for no more than 20 years, and our net operating loss carryforward generated in our taxable years ended December 31, 2019 and December 31, 2018 may be carried forward indefinitely. In connection with the MedEquities Merger on May 17, 2019, we acquired MedEquities Realty TRS, LLC. MedEquities Realty TRS, LLC has no assets, liabilities, revenues, or expenses and, accordingly, we have no tax accrual or net operating loss carryforward associated with this entity as of December 31, 2019. For the year ended December 31, 2019, 2018 and 2017, we recorded approximately $0.9 million, $0.8 million and $2.4 million, respectively, of federal, state and local income tax provision. For the year ended December 31, 2019, 2018 and 2017, we recorded a provision for foreign income taxes of approximately $2.0 million, $2.2 million and $0.8 million, respectively. The above amounts include any income or franchise taxes payable to certain states and municipalities. The following is a summary of deferred tax assets and liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ 2019 2018 ​ ​ (in thousands) Deferred tax assets: ​ ​ Federal net operating loss carryforward ​ $ 1,199 ​ $ 1,213 Total deferred assets ​ 1,199 ​ 1,213 ​ ​ ​ ​ ​ ​ ​ Deferred tax liabilities: ​ ​ Foreign deferred tax liabilities (1) ​ 11,350 ​ 13,599 Total net deferred liabilities before valuation allowances ​ (10,151) ​ (12,386) Valuation allowance on deferred tax asset ​ (1,199) ​ (1,213) Net deferred tax liabilities ​ $ (11,350) ​ $ (13,599) (1) The deferred tax liabilities primarily resulted from inherited basis differences resulting from our acquisition of entities in the U.K. Subsequent adjustments to these accounts result from GAAP to tax differences related to depreciation, indexation and revenue recognition. ​ On December 22, 2017, the Tax Cuts and Jobs Act (the "Tax Act") was enacted. The Tax Act includes numerous changes to existing U.S. tax law, including lowering the statutory U.S. federal corporate income tax rate from 35% to 21% effective January 1, 2018. The changes from the Tax Act did not have a material impact to the Company’s financial statements.

Compensation Related Costs [Abstract]
RETIREMENT ARRANGEMENTS	​ Our Company has a 401(k) Profit Sharing Plan covering all eligible employees. Under this plan, employees are eligible to make contributions, and we, at our discretion, may match contributions and make a profit sharing contribution. Amounts charged to operations with respect to these retirement arrangements totaled approximately $0.6 million in 2019, $0.5 million and $0.5 million in 2018 and 2017, respectively. 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 dividends as well as the change in the value of the Company’s common stock. As of December 31, 2019 and 2018, the Company had 459,389 and 403,427 deferred stock units outstanding.

Stockholders' / Owners' Equity [Abstract]
STOCKHOLDERS'/OWNERS' EQUITY	NOTE 17 – STOCKHOLDERS’/OWNERS’ EQUITY Forward Equity Sales Agreement ​ In connection with a $300 million underwritten public offering, we entered into a forward equity sales agreement on September 9, 2019 to sell 7.5 million shares of our common stock at an initial net price of $40.01 per share, after underwriting discounts and commissions. On December 27, 2019, we settled the forward equity sale agreement by physical delivery of 7.5 million shares of common stock at $39.45 per share, net of dividends paid and interest received, for net proceeds of approximately $295.9 million. ​ $500 Million Equity Shelf Program On September 3, 2015, we entered into separate Equity Distribution Agreements (collectively, the “Equity Shelf Agreements”) to sell shares of our common stock having an aggregate gross sales price of up to $500 million (the “2015 Equity Shelf Program”) with several financial institutions, each as a sales agent and/or principal (collectively, the “Managers”). Under the terms of the Equity Shelf Agreements, we may sell shares of our common stock, from time to time, through or to the Managers having an aggregate gross sales price of up to $500 million. Sales of the shares, if any, are 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 pay each Manager compensation for sales of the shares equal to 2% of the gross sales price per share for shares sold through such Manager under the applicable Equity Shelf Agreements. For the year ended December 31, 2017, we issued approximately 0.7 million shares under the 2015 Equity Shelf Program, at an average price of $30.81 per share, net of issuance costs, generating net proceeds of approximately $22.1 million. For the year ended December 31, 2018, we issued approximately 2.3 million shares under the 2015 Equity Shelf Program, at an average price of $33.18 per share, net of issuance costs, generating net proceeds of approximately $75.5 million. For the year ended December 31, 2019, we issued approximately 3.1 million shares under the 2015 Equity Shelf Program, at an average price of $34.79 per share, net of issuance costs, generating net proceeds of approximately $109.0 million. 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. For the year ended December 31, 2017, we issued 1.2 million shares of common stock for gross proceeds of approximately $36.7 million. For the year ended December 31, 2018, we issued 1.5 million shares of common stock for gross proceeds of approximately $46.8 million. For the year ended December 31, 2019, we issued 3.0 million shares of common stock for gross proceeds of approximately $115.1 million.

Stock-Based Compensation [Abstract]
STOCK-BASED COMPENSATION	NOTE 18 – STOCK-BASED COMPENSATION 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 partnership unit in Omega OP (“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. The following table summarizes the activity in restricted stock, RSUs, and PIUs for the years ended December 31, 2017, 2018 and 2019: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted - ​ ​ ​ Number of ​ Average Grant- ​ Compensation ​ ​ Shares/Omega ​ Date Fair Value ​ Cost (1) ​ OP Units per Share (in millions) Non-vested at December 31, 2016 336,053 $ 37.32 ​ ​ ​ Granted during 2017 185,004 ​ 31.25 ​ $ 5.8 Cancelled during 2017 (1,000) ​ 34.78 ​ Vested during 2017 (182,548) ​ 39.58 ​ Non-vested at December 31, 2017 337,509 ​ ​ 32.78 ​ Granted during 2018 217,717 ​ 28.19 ​ $ 6.1 Cancelled during 2018 (5,941) ​ 30.82 ​ Vested during 2018 (190,412) ​ 33.89 ​ Non-vested at December 31, 2018 358,873 ​ ​ 29.44 ​ Granted during 2019 160,158 ​ 35.20 ​ $ 5.6 Cancelled during 2019 (32,376) ​ 30.38 ​ Vested during 2019 (188,063) ​ 31.01 ​ Non-vested at December 31, 2019 298,592 ​ $ 31.44 ​ (1) Total compensation cost to be recognized on the awards based on grant date fair value, which is based on the market price of the Company’s common stock on the date of grant 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. The PRSUs awarded in January 2014, March 2015, April 2015, July 2015, March 2016, January 2017, January 2018, and January 2019 and the PIUs awarded in March 2015, April 2015, July 2015, March 2016, January 2017, January 2018, and January 2019 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 real estate investment trusts in the MSCI U.S. REIT Index for awards before 2016 and in the FTSE NAREIT Equity Health Care Index for awards granted in or after 2016 (both “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. Dividends on the PRSUs are accrued and only 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. The remaining partnership distributions (which in the case of normal periodic distributions is equal to the total approved quarterly dividend on Omega’s common stock) on the PIUs accumulate, and if the PIUs are earned, the accumulated distributions are paid.

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 restricted stock units, 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, 2019, approximately 4.4 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 On November 16, 2017, a purported securities class action complaint captioned Dror Gronich v. Omega Healthcare Investors, Inc., C. Taylor Pickett, Robert O. Stephenson, and Daniel J. Booth Steve Klein v. Omega Healthcare Investors, Inc., C. Taylor Pickett, Robert O. Stephenson, and Daniel J. Booth Pursuant to a Scheduling Order entered by the Court, lead plaintiff Setzer and additional plaintiff Earl Holtzman filed a Consolidated Amended Class Action Complaint on May 25, 2018 (the “Securities Class Action”). The Securities Class Action purports to be a class action brought on behalf of shareholders who acquired the Company’s securities between May 3, 2017 and October 31, 2017. The Securities Class Action alleges that the defendants violated the Securities Exchange Act of 1934, as amended (the “Exchange Act”), by making materially false and/or misleading statements, and by failing to disclose material adverse facts about the Company’s business, operations, and prospects, including the financial and operating results of one of the Company’s operators, the ability of such operator to make timely rent payments, and the impairment of certain of the Company’s leases and the uncollectibility of certain receivables. The Securities Class Action, which purports to assert claims for violations of Section 10(b) of the Exchange Act and Rule 10b-5 promulgated thereunder, as well as Section 20(a) of the Exchange Act, seeks an unspecified amount of monetary damages, interest, fees and expenses of attorneys and experts, and other relief. The Company and the officers named in the Securities Class Action filed a Motion to Dismiss on July 17, 2018. On March 25, 2019, the Court entered an order dismissing with prejudice all claims against all defendants. Plaintiffs have appealed the order to the United States Court of Appeals for the Second Circuit. The appeal is fully briefed, and the Court heard oral argument on November 13, 2019. The Company is awaiting a decision on the appeal. The Board of Directors received a demand letter, dated April 9, 2018, from an attorney representing Phillip Swan (“Swan”), a purported current shareholder of the Company, relating to the subject matter covered by the Securities Class Action (the “Swan Shareholder Demand”). The letter demanded that the Board of Directors conduct an investigation into the statements and other matters at issue in the Securities Class Action and commence legal proceedings against each party identified as being responsible for the alleged activities. After an investigation and due consideration, and in the exercise of its business judgment, the Board 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 Swan Shareholder Demand. In November 2018, the Board also received shareholder demands from two additional purported shareholders, Tom Bradley (“Bradley”) and Sarah Smith (“Smith”), each represented by the same counsel as Swan, that were substantively identical to the Swan Shareholder Demand (the “Bradley/Smith Shareholder Demands”). The Board reached the same conclusion with respect to those demands as it reached with the Swan Shareholder Demand. On August 22, 2018, Stourbridge Investments LLC, a purported stockholder of the Company, filed a derivative action purportedly on behalf of the Company in the United States District Court for the Southern District of New York against the current directors of the Company as well as certain officers alleging violations of Section 14(a) of the Securities Exchange Act of 1934 and state-law claims including breach of fiduciary duty. Stourbridge Investments LLC v. Callen et al., On January 30, 2019, Swan filed a derivative action in the Baltimore City Circuit Court of Maryland, purportedly on behalf of the Company against certain current and former directors of the Company as well as certain officers, asserting claims for breach of fiduciary duty, waste of corporate assets and unjust enrichment. Swan v. Pickett, et al., Bradley and Smith v. Callen, et al. Swan Separately, during February and March 2019, four lawsuits were filed by purported stockholders of MedEquities against MedEquities and its directors challenging the proposed merger between MedEquities and the Company. Two of the lawsuits also named the Company as a defendant. Three of these actions were dismissed during 2019, including both actions that named the Company as defendant. These actions were Brekka v. MedEquities Realty Trust, Inc., et al Scarantino v. McRoberts et al Bushansky v. MedEquities Realty Trust, Inc., et al. Russell v. MedEquities Realty Trust, Inc., et al ​ Other ​ 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. As a result of the acquisition of MedEquities, the Company owns a 51% interest in an unconsolidated partnership that owns Lakeway Hospital (the “Lakeway Partnership”). The CID requested certain documents and information related to the acquisition and ownership of Lakeway Hospital through the Lakeway Partnership. The Company has learned that the DOJ is investigating 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. The Company is cooperating fully with the DOJ in connection with the CID and has produced all of the information that has been requested to date. ​ The Company believes that the acquisition, ownership and leasing of Lakeway Hospital through the Lakeway Partnership was and is in compliance with all applicable laws. However, due to the uncertainties surrounding this matter and its ultimate outcome, we are unable to determine whether it is probable that any loss has been incurred. ​ In addition, 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, 2019, our maximum funding commitment under these indemnification agreements was approximately $12.8 million. Claims under these indemnification agreements 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. The Company does not expect to fund a material amount under these indemnification 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, 2019, are outlined in the table below (in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total commitments $ 690,361 ​ ​ Amounts funded to date (1) ​ (520,447) ​ ​ Remaining commitments ​ $ 169,914 ​ ​ (1) Includes finance costs. ​ Environmental Matters As of December 31, 2019 and 2018, we had identified conditional asset retirement obligations primarily related to the future removal and disposal of asbestos that is contained within certain of our real estate investment properties. The asbestos is appropriately contained, and we believe we are compliant with current environmental regulations. If these properties undergo major renovations or are demolished, certain environmental regulations are in place, which specify the manner in which asbestos must be handled and disposed. We are required to record the fair value of these conditional liabilities if they can be reasonably estimated. As of December 31, 2019 and 2018, no

On December 27, 2019, the Company completed the forward equity sale and issued the 7.5 million shares of common stock at a net price of $39.45 per share, and received approximately $295.9 million of net proceeds. See Note 17 – Stockholder/Owners’ Equity – Forward Equity Sales Agreement. The shares issuable prior to settlement of the forward equity sales agreement are reflected in the diluted earnings per share calculations using the treasury stock method. Under this method, the number of the Company’s common shares used in calculating diluted earnings per share is deemed to be increased by the excess, if any, of the number of common shares that would be issued upon full physical settlement of the forward equity sales agreement over the number of common shares that could be purchased by the Company in the market (based on the average market price during the period) using the proceeds receivable upon full physical settlement (based on the adjusted forward sale price at the end of the reporting period). ​

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2019
Organization, Consolidation and Presentation Of Financial Statements [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.
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	Risks and Uncertainties The Company is subject to certain risks and uncertainties affecting the healthcare industry as a result of healthcare legislation and growing 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.
Business Combinations	Business Combinations We record the purchase of properties to net tangible and identified intangible assets acquired and liabilities assumed at fair value. Transaction costs are expensed as incurred as part of a business combination. In making estimates of fair value for purposes of recording the purchase, 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. We also consider information obtained about each property as a result of our pre-acquisition due diligence, marketing and leasing activities as well as other critical valuation metrics such as current capitalization rates and discount rates used to estimate the fair value of the tangible and intangible assets acquired (Level 3). When liabilities are assumed as part of a transaction, we consider information obtained about the liabilities and use similar valuation metrics (Level 3). In some instances when debt is assumed and an identifiable active market for similar debt is present, we use market interest rates for similar debt to estimate the fair value of the debt assumed (Level 2). The Company determines fair value 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 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. ● Goodwill represents the purchase price in excess of the fair value of assets acquired and liabilities assumed. Goodwill is not amortized.
Asset Acquisitions	Asset Acquisitions For asset acquisitions, assets acquired and liabilities assumed are recognized by allocating the cost of the acquisition, including transaction costs, to the individual assets acquired and liabilities assumed on a relative fair value basis. The fair value of the assets acquired and liabilities assumed in an asset acquisition are determined in a consistent manner with the immediately preceding “Business Combinations” section.
Variable Interest Entities	Variable Interest Entities 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 variable interest entities (“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, 2019, we have not consolidated any VIEs, as we do not have the power to direct the activities of any VIEs that most significantly impact their economic performance and we do not have the obligation to absorb losses or receive benefits of the VIEs that could be significant to the entities.
Real Estate Investments and Depreciation	Real Estate Investments and Depreciation The costs of significant improvements, renovations and replacements, including interest are capitalized. 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 charged to operations 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
Lease Accounting	Lease Accounting In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02, Leases (Topic 842) Leases (Topic 842): Land Easement Practical Expedient for Transition to Topic 842 Leases (Topic 842): Codification Improvements to Topic 842, Leases Leases (Topic 842): Targeted Improvements Leases (Topic 842): Narrow-Scope Improvements for Lessors Lessor Accounting Topic 842 requires lessors to account for leases using an approach that is substantially equivalent to the previous guidance for sales type leases, direct financing leases and operating leases. At the inception of the lease and over its term, we evaluate each lease to determine the proper lease classification. Certain of these leases provide our operators the contractual right to use and economically benefit from all of the physical space specified in the lease, therefore we have determined that they should be evaluated as lease arrangements. As a lessor, our leased real estate properties are leased under provisions of single or master leases with initial terms typically ranging from 5 to 15 years, plus renewal options. As of December 31, 2019, we have determined that all but two of our leases should be accounted for as operating leases. Two leases are accounted for as direct financing leases. Under the terms of the leases, the lessee is responsible for all maintenance, repairs, taxes and insurance on the leased properties. For leases accounted for as operating leases, we retain ownership of the asset and record depreciation expense, see “Business Combinations” and “Real Estate Investments and Depreciation” above for additional information regarding our investment in real estate leased under operating lease agreements. We also record lease revenue based on the contractual terms of the operating lease agreement which often includes annual rent escalators, see “Revenue Recognition” below for further discussion regarding the recordation of revenue on our operating leases. 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. Certain direct financing leases include annual rent escalators; see “Revenue Recognition” below for further discussion regarding the recording of interest income on our direct financing leases. As of December 31, 2019 and 2018, we have no unamortized direct costs related to originating our direct financing leases recorded on our Consolidated Balance Sheets. Lessee Accounting At the inception of the lease and over its term, we evaluate each lease to determine the proper lease classification. Certain of these leases provide us the contractual right to use and economically benefit from all of the space specified in the lease. Therefore, we have determined that they should be evaluated as lease arrangements. As a lessee, the Company is party to ground and/or facility leases which are classified as operating leases. Substantially all of our operating leases contain provisions for specified annual increases over the rents of the prior year and are generally computed in one of three methods depending on the specific provisions of each lease as follows: (i) a specific annual increase over the prior year’s rent, generally between 1.0% and 3.0%; (ii) an increase based on the change in pre-determined formulas from year to year (e.g., increases in the Consumer Price Index); or (iii) specific dollar increases over prior years. The initial terms of our ground leases range between 10 years and 100 years. Our office leases have initial terms of approximately 10 years. 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 right-of-use assets and lease liabilities. The discount rate utilized in forming the basis of our right of use assets and lease liabilities approximates our cost of debt. We have not recognized a right of use asset and/or lease liability for leases with terms of 12 months or less and without an option to purchase the underlying asset. On a monthly basis, we remeasure 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. 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. As a lessee, certain of our operating leases contain non-lease components, such as our proportionate share of common area expenses. We have determined that all of our operating leases qualify for the practical expedient 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. We apply Topic 842 to the combined component. Lease expense derived from our operating leases is recorded in general and administrative in our Consolidated Statements of Operations.
In-Place Leases	In-Place Leases In-place lease assets and liabilities result when we assume a lease as part of a facility purchase 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.
Real Estate Investment Impairment	Real Estate Investment Impairment Management evaluates our real estate investments 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 are probability-weighted based on management’s best estimates as of the date of evaluation. Provisions for 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 consider 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 the Company’s assets in a future period that could be material to the Company’s results of operations. For the years ended December 31, 2019, 2018 and 2017, we recognized impairment on real estate properties of $45.3 million, $29.8 million and $99.1 million, respectively.
Allowance for Losses on Mortgages, Other Investments and Direct Financing Leases	Allowance for Losses on Mortgages, Other Investments and Direct Financing Leases The allowances for losses on mortgage notes receivable, other investments and direct financing leases (collectively, our “loans”) are maintained at a level believed adequate to absorb potential losses. The determination of the allowances is based on a quarterly evaluation of these loans, including general economic conditions and estimated collectability of loan payments. We evaluate the collectability of our loans receivable based on a combination of factors, including, but not limited to, delinquency status, financial strength of the borrower and guarantors and the value of the underlying collateral. If such factors indicate that there is greater risk of loan charge-offs, additional allowances or placement on non-accrual status may be required. A loan is 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. Consistent with this definition, all loans on non-accrual status may be deemed impaired. To the extent circumstances improve and the risk of collectability is diminished, we will return these loans to full accrual status. When management identifies potential loan impairment indicators, the loan is written down to the present value of the expected future cash flows. In cases where expected future cash flows are not readily determinable, the loan is written down to the fair value of the underlying collateral. We may base our valuation on a loan’s observable market price, if any, or the fair value of collateral, net of sales costs, if the repayment of the loan is expected to be provided solely by the sale of the collateral. We account for impaired loans and direct financing leases using (a) the cost-recovery method, and/or (b) the cash basis method. We generally utilize the cost-recovery method for impaired loans or direct financing leases for which impairment reserves were recorded. We utilize the cash basis method for impaired loans or direct financing leases for which no impairment reserves were recorded because the net present value of the discounted cash flows expected under the loan or direct financing lease and/or the underlying collateral supporting the loan or direct financing lease were equal to or exceeded the book value of the loans or direct financing leases. Under the cost-recovery method, we apply cash received against the outstanding loan balance or direct financing lease 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. As of December 31, 2019 and 2018, we had $5.1 million and $108.1 million, respectively, of reserves on our loans.
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. The accounting policies for the unconsolidated joint ventures are the same as those of the Company. 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 loss on our investments in unconsolidated joint ventures was recognized during the years ended December 31, 2019, 2018, or 2017.
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.
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.
Contractual Receivables and Other Receivables and Lease Inducements	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. We assess the probability of collecting substantially all payments under our leases based on several factors, including, among other things, payment history of the lessee, the financial strength of the lessee and any guarantors, historical operations and operating trends and current and future economic conditions and expectations of performance. 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 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. 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. On a quarterly basis, and more frequently as appropriate, we review our contractual interest receivables, effective yield interest receivables and direct financing lease receivables to determine their collectability. The determination of collectability of these assets requires significant judgment and is affected by several factors relating to the credit quality of our operators that we regularly monitor, including (i) payment history, (ii) the age of the contractual receivables, (iii) the current economic conditions and reimbursement environment, (iv) the ability of the operator to perform under the terms of their lease and/or contractual loan agreements and (v) the value of the underlying collateral of the agreement, if any. For a loan recognized on an effective yield basis or a direct financing lease, we generally provide an allowance for effective interest or income from direct financing leases when certain conditions or indicators of adverse collectability are present. If these accounts receivable balances are subsequently deemed uncollectible, the receivable and allowance for doubtful account balance are written off. A summary of our net receivables and inducements by type is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, ​ ​ 2019 2018 ​ ​ (in thousands) ​ Contractual receivables ​ $ 27,122 ​ $ 34,901 ​ Allowance ​ — ​ (1,075) ​ Contractual receivables – net ​ $ 27,122 ​ $ 33,826 ​ ​ ​ ​ ​ ​ ​ ​ ​ Effective yield interest receivables ​ $ 12,914 ​ $ 12,741 ​ Straight-line rent receivables ​ 275,549 ​ 251,166 ​ Lease inducements ​ 92,628 ​ 49,644 ​ Other receivables and lease inducements ​ $ 381,091 ​ $ 313,551 ​ ​ In 2019, we wrote-off approximately $11.1 million of contractual receivables, straight-line rent receivables and lease inducements to rental income, of which $9.9 million resulted from placing five operators on a cash-basis due to changes in our evaluation of the collectability of future rent payments due under the respective lease agreements. The remaining $1.2 million write-off of straight-line rent receivables to rental income resulted from transitioning a facility to another existing operator. In 2019, we paid certain operators $50.8 million which were accounted for as lease inducements that are amortized as a reduction to rental income over the remaining term of the lease. Of the $50.8 million, $15.0 million was paid to Genesis Healthcare, Inc. and $35.8 million was paid to seven other existing operators. In 2018, we paid an existing operator approximately $50 million in exchange for a reduction of such operator’s participation in an in-the-money purchase option. As a result, we recorded an approximate $28 million lease inducement that is being amortized as a reduction to rental income over the remaining term of the lease. The remaining $22 million was recorded as a reduction to our initial contingent liability. Our initial contingent liability was recorded in our merger with Aviv REIT, Inc. and included in accrued expenses and other liabilities on our Consolidated Balance Sheets. In 2018, we wrote-off approximately $11.5 million of straight-line rent receivables and contractual receivables to provision for uncollectible accounts, as a result of facility transitions and placing an operator on a cash basis. The provision for uncollectible accounts was offset by a recovery of approximately $4.8 million. In 2017, we recorded a provision for uncollectible accounts of approximately $9.3 million related to contractual and straight-line rent receivables for one of our operators and approximately $4.1 million of provision for uncollectible accounts, net of recoveries related to contractual and straight-line receivables of other operators and/or facilities that we intend to exit or transition.
Goodwill Impairment	Goodwill Impairment We assess goodwill for potential impairment during the fourth quarter of each fiscal year, or during the year 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 on an interim basis, 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 is, a likelihood of more than 50 percent) that the fair value of the reporting unit is less than its carrying amount. On an annual basis during the fourth quarter of each fiscal year, or on an interim basis if we conclude it is more likely than not that the fair value of the reporting unit is less than its carrying value, we perform a two-step goodwill impairment test to identify potential impairment and measure the amount of impairment we will recognize, if any. The goodwill is not deductible for tax purposes. ​ In the first step of the two-step goodwill impairment test (“Step 1”), we compare the fair value of the reporting unit to its net book value, including goodwill. As the Company has only one reporting unit, the fair value of the reporting unit is determined by reference to the market capitalization of the Company as determined through quoted market prices and adjusted for other relevant factors. A potential impairment exists if the fair value of the reporting unit is lower than its net book value. The second step (“Step 2”) of the process is only performed if a potential impairment exists, and it involves determining the difference between the fair value of the reporting unit’s net assets other than goodwill and the fair value of the reporting unit. If the difference is less than the net book value of goodwill, impairment exists and is recorded. The Company has not been required to perform Step 2 of the process because the fair value of the reporting unit has significantly exceeded its book value at the measurement date. There was no impairment of goodwill during 2019, 2018, or 2017.
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 United States 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 carryforwards. 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.
Revenue Recognition	Revenue Recognition On January 1, 2018, we adopted ASU 2014-09, Revenue from Contracts with Customers We have various investments that generate revenue, including leased and mortgaged properties, as well as other investments, which include secured and unsecured loans. Rental income Substantially all of our operating leases contain provisions for specified annual increases over the rents of the prior year and are generally computed in one of three methods depending on the specific provisions of each lease as follows: (i) a specific annual increase over the prior year’s rent, generally between 2.0% and 3.0%; (ii) an increase based on the change in pre-determined formulas from year to year (e.g., increases in the Consumer Price Index); or (iii) specific dollar increases over prior years. Rental income from operating leases is generally recognized on a straight-line basis over the lease term when we have determined that the collectibility of substantially all of the lease payments is probable. If we determine that it is not probable that substantially all of the lease payments will be collected, we account for the revenue under the lease on a cash basis. Changes in the assessment of probability are accounted for on a cumulative basis as if the lease had always been accounted for based on the current determination of the likelihood of collection potentially resulting in increased volatility of rental revenue. Some of our leases have options to extend, terminate or purchase the facilities, which are considered when determining the lease term. We do not include in our measurement of our lease receivables certain variable payments, including changes in an index until the specific events that trigger the variable payments have occurred. 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 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. We apply Topic 842 to the combined component. Income derived from our leases is recorded in rental income in our Consolidated Statements of Operations. Prior to the adoption of Topic 842, we did not include amounts for property taxes and other expenditures in rental income. We have elected to exclude sales and other similar taxes from the measurement of lease revenue and expense. Income from direct financing leases We record direct financing lease income on a constant interest rate basis over the term of the lease. 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. Mortgage interest income and other investment income Mortgage interest income and other investment income is recognized as earned over the terms of the related mortgage notes or other investment. 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.
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 $9.6 million, $9.0 million and $9.5 million in 2019, 2018 and 2017, respectively, and are classified as interest - amortization of deferred financing costs 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 interest-refinancing costs on our Consolidated Statements of Operations.
Earnings Per Share/Unit	Earnings Per Share/Unit The computation of basic earnings per share/unit (“EPS” or “EPU”) is computed by dividing net income available to common stockholders/Omega OP Unit holders by the weighted-average number of shares of common stock/Omega OP Units outstanding during the relevant period. Diluted EPS/EPU is computed using the treasury stock method, which is net income divided by the total weighted-average number of common outstanding shares/Omega OP Units plus the effect of dilutive common equivalent shares/units during the respective period. Dilutive common shares/Omega OP Units 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 and the effect of our forward equity agreement. Dilutive Omega OP Units reflect the assumed issuance of additional Omega OP Units pursuant to certain of our share-based compensation plans, including, restricted stock and profit interest units, performance restricted stock and profit interest units and the effect of our forward equity agreement.
Redeemable Limited Partnership Unitholder Interests and Noncontrolling Interests	Redeemable Limited Partnership Unitholder Interests and Noncontrolling Interests 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 the Partnership Agreement. As of December 31, 2019, Omega owns approximately 97% of the issued and outstanding Omega OP Units, and investors own approximately 3% of the outstanding Omega OP Units.
Noncontrolling Interests	Noncontrolling 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 or owners’ 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. The noncontrolling interest for Omega OP represents outside investors interests in a consolidated real estate joint venture not fully owned by Omega OP.
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”). For our consolidated subsidiaries whose functional currency is not the USD, we translate their financial statements into the USD. We translate assets and liabilities at the exchange rate in effect as of the financial statement date. Revenue and expense accounts are translated using an average exchange rate for the period. Gains and losses resulting from translation are included in Omega OP’s owners’ equity and Omega’s accumulated other comprehensive loss (“AOCL”), 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, unless it is intercompany debt that is deemed to be long-term in nature in which case the adjustments are included in Omega OP’s owners’ equity and Omega’s AOCL and a proportionate amount of gain or loss is allocated to noncontrolling interests, if applicable.
Derivative Instruments	Derivative Instruments Cash flow hedges During our normal course of business, we may use certain types of derivative instruments for the purpose of managing interest rate and currency risk. To qualify for hedge accounting, derivative instruments used for risk management purposes must effectively reduce the risk exposure that they are designed to hedge. 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 earnings. For derivatives designated in qualifying cash flow hedging relationships, the gain or loss on the derivative is recognized in Omega OP’s owners’ equity and Omega’s AOCL as a separate component of equity and a proportionate amount of gain or loss is allocated to noncontrolling interest, if applicable. 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. We also assess and document, both at inception of the hedging relationship and on a quarterly basis thereafter, whether the derivatives are highly effective in offsetting the designated risks associated with the respective hedged items. If it is determined that a derivative ceases to be highly effective as a hedge, or that it is probable the underlying forecasted transaction will not occur, we discontinue hedge accounting prospectively and record the appropriate adjustment to earnings based on the current fair value of the derivative. As a matter of policy, we do not use derivatives for trading or speculative purposes. At December 31, 2019, $3.7 million of qualifying cash flow hedges were recorded at fair value in accrued expenses and other liabilities on our Consolidated Balance Sheet. At December 31, 2018, $4.0 million of qualifying cash flow hedges were recorded at fair value in other assets on our Consolidated Balance Sheet. Net investment hedge The Company is exposed to fluctuations in the GBP against its functional currency, the USD, relating to its investments in healthcare-related real estate properties located in the U.K. The Company uses a nonderivative, GBP-denominated term loan to manage its exposure to fluctuations in the GBP-USD exchange rate. The foreign currency transaction gain or loss on the nonderivative hedging instrument that is designated and qualifies as a net investment hedge is reported in Omega OP’s owners’ equity and Omega’s AOCL in our Consolidated Balance Sheets.
Reclassification	Reclassification
Recently and Pending Adoption Accounting Pronouncements	Accounting Pronouncements Adopted in 2019 Topic 842 sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). Topic 842 requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. Topic 842 requires lessors to account for leases using an approach that is substantially equivalent to the previous guidance for sales type leases, direct financing leases and operating leases. Topic 842 was adopted by us on January 1, 2019 using the modified retrospective method. Upon adoption, we applied the package of practical expedients that allowed us to not reassess (i) whether any expired or existing contracts are or contain leases, (ii) lease classification for any expired or existing leases and (iii) initial direct costs for any expired or existing leases. Furthermore, we applied the optional transition method, which allowed us to initially apply Topic 842 at the adoption date and recognize a cumulative effect adjustment to the opening balance of equity in the period of adoption. During the year ended December 31, 2019, we made an adjustment of approximately $8.5 million to the equity balance to reflect our assessment of the collectability of certain operator’s future contractual lease payments based on the facts and circumstances that existed as of January 1, 2019. ​ In addition, provisions for uncollectible lease payments are recognized as a direct reduction to rental income. Prior to our adoption of Topic 842, provisions for uncollectible lease payments were recorded in provision for uncollectible accounts on our Consolidated Statements of Operations and were not reclassified to conform to the current period presentation. ​ Upon adoption of Topic 842, we recorded total initial non-cash right of use assets and lease liabilities of approximately $11.1 million. We also began recording variable lease payments as rental income and real estate tax expense for those facilities’ property taxes that we pay directly and are reimbursed by our operators. For the year ended December 31, 2019, we recorded $12.1 million of rental income and $14.9 million of real estate tax expense in our Consolidated Statement of Operations.

The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for credit losses. The measurement of expected credit losses is based upon historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019. ASU 2016-13 specifically excludes from its scope receivables arising from operating leases accounted for under Topic 842. We plan to adopt ASU 2016-13 on January 1, 2020 using the modified retrospective approach. Therefore, financial information and disclosures under ASU 2016-13 will not be provided for periods prior to January 1, 2020. We are in the process of finalizing a company-wide governance structure, which provides implementation oversight to develop a credit loss methodology compliant with the standard. Our methodology includes consideration of historical losses, the credit profiles of our borrowers and/or lessees, and reasonable and supportable forecasts with respect to expected credit losses over the life of the asset. Certain of the Company’s financial assets which are not currently reserved for are within the scope of ASU 2016-13. These financial assets primarily include our investments in direct financing leases, mortgages notes receivable and other investments. We continue to evaluate the initial and subsequent impacts of adopting ASU 2016-13 on our consolidated financial statements.

In 2019, we sold seven facilities for approximately $22.9 million in net proceeds recognizing a gain on sale of approximately $14.8 million. One facility classified as held for sale at December 31, 2018 was no longer considered held for sale during the second quarter of 2019 and was reclassified to leased property at approximately $0.3 million which represents the facility’s then carrying value adjusted for depreciation that was not recognized while classified as held for sale. (2) In 2018, we recorded approximately $13.0 million of impairment expense to reduce 26 facilities and one ancillary building's book value to their estimated fair values less costs to sell before they were reclassified to assets held for sale. In 2019, we recorded approximately $9.2 million of impairment expense to reduce eight facilities’ book values to their estimated fair values less costs to sell before they were reclassified to assets held for sale. (3) We plan to sell the facilities classified as held for sale at December 31, 2019 within the next twelve months.
