Common Stock/Partner's Capital

9. Common Stock/Partner’s Capital

Medical Properties Trust, Inc.

2020 Activity

In 2020, we sold 21.0 million shares of common stock under our at-the-market equity offering program, resulting in net proceeds of approximately $411 million.

2019 Activity

On November 4, 2019, we filed Articles of Amendment to our charter with the Maryland State Department of Assessments and Taxation increasing the number of authorized shares of common stock, par value $0.001 per share, available for issuance from 500 million to 750 million.

On November 8, 2019, we completed an underwritten public offering of 57.5 million shares (including the exercise of the underwriters’ 30-day option to purchase an additional 7.5 million shares) of our common stock, resulting in net proceeds of $1.026 billion, after deducting underwriting discounts and commissions and offering expenses.

On July 18, 2019, we completed an underwritten public offering of 51.75 million shares (including the exercise of the underwriters’ 30-day option to purchase an additional 6.75 million shares) of our common stock, resulting in net proceeds of $858.1 million, after deducting underwriting discounts and commissions and offering expenses.

In 2019, we sold 36.1 million shares of common stock under our at-the-market equity offering program, resulting in net proceeds of approximately $650 million.

On December 27, 2019, we entered into a new at-the-market equity offering program, which gives us the ability to sell up to $1.0 billion of stock with a commission rate up to 2.0%.

2018 Activity

In the 2018 fourth quarter, we sold 5.6 million shares of common stock under our at-the-market equity offering program, resulting in net proceeds of approximately $95 million.

MPT Operating Partnership, L.P.

At December 31, 2020, the Operating Partnership is made up of a general partner, Medical Properties Trust, LLC (“General Partner”) and limited partners, including the Company (which owns 100% of the General Partner) and MPT TRS, Inc. (which is 100% owned by the General Partner). By virtue of its ownership of the General Partner, the Company has a 100% ownership interest in the Operating Partnership via its ownership of the common units and its indirect ownership of MPT TRS, Inc.

In regards to distributions, the Operating Partnership shall distribute cash at such times and in such amounts as are determined by the General Partner in its sole and absolute discretion, to common unit holders who are common unit holders on the record date. However, per the Second Amended and Restated Agreement of Limited Partnership of MPT Operating Partnership, L.P. (“Operating Partnership Agreement”), the General Partner shall use its reasonable efforts to cause the Operating Partnership to distribute amounts sufficient to enable the Company to pay stockholder dividends that will allow the Company to (i) meet its distribution requirement for qualification as a REIT and (ii) avoid any U.S. federal income or excise tax liability imposed by the Code, other than to the extent the Company elects to retain and pay income tax on its net capital gain. In accordance with the Operating Partnership Agreement, LTIP units are treated as common units for distribution purposes.

The Operating Partnership’s net income will generally be allocated first to the General Partner to the extent of any cumulative losses and then to the limited partners in accordance with their respective percentage interests in the common units issued by the Operating Partnership. Any losses of the Operating Partnership will generally be allocated first to the limited partners until their capital account is zero and then to the General Partner. In accordance with the Operating Partnership Agreement, LTIP units are treated as common units for purposes of income and loss allocations. Limited partners have the right to require the Operating Partnership to redeem part or all of their common units. It is at the Operating Partnership’s discretion to redeem such common units for cash based on the fair market value of an equivalent number of shares of the Company’s common stock at the time of redemption or, alternatively, redeem the common units for shares of the Company’s common stock on a one-for-one basis, subject to adjustment in the event of stock splits, stock dividends, or similar events. LTIP units must wait two years from the issuance of the LTIP units to be redeemed, and then converted to common units. On December 28, 2020, approximately 232 thousand LTIP units were converted to common units and then redeemed for approximately $4.9 million of cash. In 2018, approximately 60 thousand LTIP units were converted to common units and then redeemed for approximately $0.8 million of cash.

For each share of common stock issued by Medical Properties Trust, Inc., the Operating Partnership issues a corresponding number of operating partnership units.

Credit Facility

Our current unsecured credit facility (“Credit Facility”) includes a $1.3 billion unsecured revolving loan facility and a $200 million unsecured term loan facility. At December 31, 2020, the maturity date of our unsecured revolving loan facility was in February 2021, while our term loan’s maturity date was February 1, 2022. The term loan and/or revolving loan commitments could be increased in an aggregate amount not to exceed $500 million.

At our election, loans under the Credit Facility could be made as either ABR Loans or Eurodollar Loans. The applicable margin for term loans that are ABR Loans was adjustable on a sliding scale from 0.00% to 0.95% based on our current credit rating. The applicable margin for term loans that are Eurodollar Loans was adjustable on a sliding scale from 0.90% to 1.95% based on our current credit rating. The applicable margin for revolving loans that are ABR Loans was adjustable on a sliding scale from 0.00% to 0.65% based on our current credit rating. The applicable margin for revolving loans that are Eurodollar Loans was adjustable on a sliding scale from 0.875% to 1.65% based on our current credit rating. The commitment fee was adjustable on a sliding scale from 0.125% to 0.30% based on our current credit rating and was payable on the revolving loan facility.

At December 31, 2020, we had $165.4 million outstanding on the revolving credit facility, whereas, we had no outstanding borrowings on our revolving credit facility at December 31, 2019. At December 31, 2020 and 2019, our availability under our revolving credit facility was $1.1 billion and $1.3 billion, respectively. The weighted-average interest rate on the revolving facility was 1.4% and 2.0% during 2020 and 2019, respectively.

At December 31, 2020 and 2019, the interest rate in effect on our term loan was 1.65% and 3.30%, respectively.

Our Credit Facility was amended in January 2021 – see Note 13 for details of this amendment.

Non-U.S. Term Loans

British Pound Sterling Term Loan

On January 6, 2020, we entered into a £700 million unsecured sterling-denominated term loan with Bank of America, N.A., as administrative agent, and several lenders from time-to-time are parties thereto. The term loan matures on January 15, 2025. The applicable margin under the term loan is adjustable based on a pricing grid from 0.85% to 1.65% dependent on our current credit rating. On March 4, 2020, we entered into an interest rate swap transaction (effective March 6, 2020) to fix the interest rate to approximately 0.70% for the duration of the loan. The current applicable margin for the pricing grid (which can vary based on our credit rating) is 1.25% for an all-in fixed rate of 1.95%.

Australian Term Loan

On May 23, 2019, we entered into an A$1.2 billion term loan with Bank of America, N.A., as administrative agent, and several lenders from time-to-time are parties thereto. The term loan matures on May 23, 2024. The interest rate under the term loan is adjustable based on a pricing grid from 0.85% to 1.65%, dependent on our current senior unsecured credit rating. On June 27, 2019, we entered into an interest rate swap transaction (effective July 3, 2019) to fix the interest rate to approximately 1.20% for the duration of the loan as long as the reference rate stays above 0.00%. The current applicable margin for the pricing grid (which can vary based on our credit rating) is 1.25% for an all-in fixed rate of 2.45%.

At December 31, 2020 and 2019, we had a derivative liability of approximately $51.3 million and $5.6 million, respectively, included in "Accounts payable and accrued expenses" in our consolidated balance sheets associated with these interest rate swaps.

Senior Unsecured Notes

The following are the basic terms of our senior unsecured notes. Typically, we may redeem some or all of the notes at any time, but may require a redemption premium that will decrease over time. In the event of a change of control, each holder of the notes may

require us to repurchase some or all of our notes at a repurchase price equal to 101% of the aggregate principal amount of the notes plus accrued and unpaid interest to the date of purchase.

Other Activity

In preparation of the joint venture with Primotop described under “2018 Activity” in Note 3, we issued secured debt on August 3, 2018, resulting in gross proceeds of €655 million. Provisions of the secured debt included a term of seven years and a swapped fixed rate of approximately 2.3%. Subsequently, on August 31, 2018, the secured debt was contributed along with the related real estate of 71 properties to form the joint venture.

Debt Refinancing and Unutilized Financing Costs

2020

With proceeds from our $1.3 billion, 3.500% Senior Unsecured Notes due 2031 offering completed on December 4, 2020, we redeemed all of our outstanding $500.0 million aggregate principal amount of 6.375% Senior Unsecured Notes due 2024 and $300.0 million aggregate principal amount of 5.500% Senior Unsecured Notes due 2024, including accrued and unpaid interest. As a result of these redemptions, we incurred a charge of approximately $28 million (including redemption premiums and accelerated amortization of deferred debt issuance costs).

2019

On July 10, 2019, we received a commitment to provide a senior unsecured bridge loan facility to fund our investment in Prospect. With this commitment, we paid approximately $4 million of underwriting and other fees. However, this commitment was cancelled with the completion of the debt and equity offerings in July 2019 (as more fully described above and in Note 9), which resulted in fully expensing the total amount of underwriting and other fees that were paid.

In anticipation of funding our Australian acquisition in June 2019 and the Circle transaction in January 2020, we entered into term loans on the date these deals were signed that had a delayed draw feature. This feature allowed for us to not draw on the term loans until needed to fund these transactions. However, with this type of structure, we incurred approximately $2.0 million in accelerated debt issue cost amortization expense during 2019.

Covenants

Our debt facilities impose certain restrictions on us, including restrictions on our ability to: incur debts; create or incur liens; provide guarantees in respect of obligations of any other entity; make redemptions and repurchases of our capital stock; prepay, redeem, or repurchase debt; engage in mergers or consolidations; enter into affiliated transactions; dispose of real estate or other assets; and change our business. In addition, the credit agreements governing our Credit Facility limit the amount of dividends we can pay as a percentage of normalized adjusted funds from operations (“NAFFO”), as defined in the agreements, on a rolling four quarter basis. Through 2020, the dividend restriction was 95% of NAFFO. The indentures governing our senior unsecured notes also limit the amount of dividends we can pay based on the sum of 95% of NAFFO, proceeds of equity issuances and certain other net cash proceeds. Finally, our senior unsecured notes require us to maintain total unencumbered assets (as defined in the related indenture) of not less than 150% of our unsecured indebtedness.

In addition to these restrictions, the Credit Facility contains customary financial and operating covenants, including covenants relating to our total leverage ratio, fixed charge coverage ratio, secured leverage ratio, consolidated adjusted net worth, unsecured leverage ratio, and unsecured interest coverage ratio. The Credit Facility also contains customary events of default, including among others, nonpayment of principal or interest, material inaccuracy of representations, and failure to comply with our covenants. If an event of default occurs and is continuing under the Credit Facility, the entire outstanding balance may become immediately due and payable. At December 31, 2020, we were in compliance with all such financial and operating covenants.

Medical Properties Trust, Inc.

We have maintained and intend to maintain our election as a REIT under the Code. To qualify as a REIT, we must meet a number of organizational and operational requirements, including a requirement to distribute at least 90% of our taxable income to our stockholders. As a REIT, we generally will not be subject to U.S. federal income tax if we distribute 100% of our taxable income to our stockholders and satisfy certain other requirements; instead, income tax is paid directly by our stockholders on the dividends distributed to them. If our taxable income exceeds our dividends in a tax year, REIT tax rules allow us to designate dividends from the subsequent tax year in order to avoid current taxation on undistributed income. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income taxes at regular corporate rates, including any applicable alternative minimum tax. Taxable income from non-REIT activities managed through our TRS is subject to applicable U.S. federal, state, and local income taxes. Our international subsidiaries are also subject to income taxes in the jurisdictions in which they operate.

The foreign provision for income taxes is based on foreign profit before income taxes of $62.1 million, $10.7 million, and $18.6 million in 2020, 2019, and 2018, respectively.

The domestic provision for income taxes is based on income before income taxes of $6.4 million in 2020 as compared with a loss before income taxes of $(44.1) million in 2019 from our TRS and income before income taxes of $8.0 million in 2018.

At December 31, 2020 and 2019, components of our deferred tax assets and liabilities were as follows (in thousands):

	2020			2019

Valuation Allowance

A valuation allowance has been recorded on certain foreign and domestic net operating loss carryforwards and other net deferred tax assets that may not be realized. As of each reporting date, we consider all new evidence that could impact the future realization of our deferred tax assets. In the evaluation of the need for a valuation allowance on our deferred income tax assets, we consider all available positive and negative evidence, including scheduled reversals of deferred income tax liabilities, carryback of future period losses to prior periods, projected future taxable income, tax planning strategies, and recent financial performance.

During 2020, a valuation allowance of $25.6 million has been recorded against a portion of our international deferred tax assets to recognize only the components of the deferred tax assets that is more likely than not to be realized. The valuation allowance was primarily recorded against deferred tax assets for NOLs, non-depreciable basis of real property, and other tax attributes that we believe will not be realized.

We have no material uncertain tax position liabilities and related interest or penalties.

REIT Status

We have met the annual REIT distribution requirements by payment of at least 90% of our taxable income in 2020, 2019, and 2018. Earnings and profits, which determine the taxability of such distributions, will differ from net income reported for financial reporting purposes due primarily to differences in cost basis, differences in the estimated useful lives used to compute depreciation, and differences between the allocation of our net income and loss for financial reporting purposes and for tax reporting purposes.

A schedule of per share distributions we paid and reported to our stockholders is set forth in the following:

	For the Years Ended December 31,
	2020		2019		2018
Common share distribution	$	1.070000	$	1.010000	$	0.990000
Ordinary income		0.603050		0.701910		0.438792
Capital gains(1)		—		0.275040		0.551208
Unrecaptured Sec. 1250 gain		—		0.041160		0.132280
Section 199A Dividends		0.603050		0.701910		0.438792
Return of capital		0.466950		0.033050		—

(1)Capital gains include unrecaptured Sec. 1250 gains.

MPT Operating Partnership, L.P.

As a partnership, the allocated share of income of the Operating Partnership is included in the income tax returns of the general and limited partners. Accordingly, no accounting for income taxes is generally required for such income of the Operating Partnership. However, the Operating Partnership has formed a TRS on behalf of Medical Properties Trust, Inc., which is subject to U.S. federal, state, and local income taxes at regular corporate rates, and its international subsidiaries are subject to income taxes in the jurisdictions in which they operate. See discussion above under Medical Properties Trust, Inc. for more details of income taxes associated with our TRS and international operations.

Leases [Abstract]

Leases (Lessee)

11. Leases (Lessee)

We lease the land underlying certain of our facilities (for which we sublease to our tenants), along with corporate office and equipment. Our leases have remaining lease terms that vary in years, and some of the leases have initial fixed terms (or renewal options available) that extend the leases up to, or just beyond, the depreciable life of the properties that occupy the leased land. Renewal options that we are reasonably certain to exercise are recognized in our right-of-use assets and lease liabilities. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at lease commencement date in determining the present value of future payments.

The following is a summary of our lease expense (in thousands):

	Income Statement	For the Years Ended December 31,
	Classification	2020			2019

Total lease cost		$	7,475		$	5,952

Includes short-term leases.

For 2018, our total lease expense was $9.4 million, which was offset by sublease rental income of $4.3 million.

On December 30, 2020, we entered into definitive agreements to acquire a portfolio of between 35 and 40 behavioral health facilities located throughout the United Kingdom for an aggregate purchase price of approximately £800 million from the Priory Group. The transaction is structured to occur in two primary phases. On December 30, 2020, an affiliate of Waterland Private Equity Fund VII C.V. (“Waterland VII”) entered into definitive agreements to acquire all of the outstanding equity interests in the entity that owns the Priory Group from its current owner, Acadia Healthcare Company, Inc. In separate agreements entered into with Waterland VII on the same date, we agreed to provide a short-term interim acquisition loan to Waterland VII at the closing of Waterland VII’s acquisition of Priory Group.

Upon closing of the first phase of the transaction on January 19, 2021, we funded an £800 million interim acquisition loan secured by mortgages on an identified portfolio of Priory Group real estate assets. In phase two, in a series of transactions we expect will be completed during the first half of 2021, we will acquire a portfolio of select real estate assets from Priory Group (now owned by Waterland VII) in individual sale-and-leaseback transactions, subject to customary real estate and other closing conditions. As all conditions to closing for a particular asset are satisfied, the applicable purchase price for the asset will be paid by us by proportionally converting and reducing the principal balance of the interim acquisition loan we made to Waterland VII in phase one. The aggregate purchase price for the real estate assets we acquire from the Priory Group is thus expected to be approximately £800 million, being the total amount of the interim acquisition loan, plus customary stamp duty, tax and other transaction costs.

The properties we acquire will be subject to a master lease type structure with an initial term of 25 years and two 10-year extension options, with annual inflation-based escalators. Pending its conversion and offset, the initial interim acquisition loan will bear interest at a rate similar to the initial lease rate we will receive under the lease transactions.

In addition to the £800 million initial interim acquisition loan described above, we also agreed to provide Waterland VII with a 364-day £250 million acquisition loan, which we funded on January 19, 2021, in connection with the closing of Waterland VII’s acquisition of the Priory Group. The loan is secured by the same security assets securing the £800 million interim acquisition loan.

In connection with these transactions, we also acquired a 9.9% passive equity interest in the Waterland VII affiliate that indirectly owns the Priory Group for a nominal amount.

To help fund this acquisition, we entered into a $900 million interim credit facility on January 15, 2021, of which we utilized £500 million along with £350 million from our revolving facility and the rest from cash on-hand.

Contingencies

We are a party to various legal proceedings incidental to our business. In the opinion of management, after consultation with legal counsel, the ultimate liability, if any, with respect to these proceedings is not presently expected to materially affect our financial position, results of operations, or cash flows.

Accounting Policies [Abstract]

Use of Estimates

Use of Estimates: The preparation of our consolidated financial statements in conformity with accounting principles generally accepted in the U.S. requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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. During 2020, the global outbreak of a novel coronavirus, or COVID-19, spread all over the world including countries where we own and lease facilities. The World Health Organization designated COVID-19 as a pandemic, and numerous countries, including the U.S., declared national emergencies with respect to COVID-19. As the global impact of the outbreak evolved, many countries reacted by instituting quarantines and restrictions on travel, closing financial markets and/or restricting trade- including requiring medically necessary elective surgeries at hospitals to be deferred. Although hospitals are back accepting patients and performing medically necessary elective surgeries, many of these trade restrictions are still in place. We believe the estimates and assumptions underlying our consolidated financial statements are reasonable and supportable based on the information available as of December 31, 2020 (particularly as it relates to our assessments of the recoverability of our real estate and the adequacy of our credit loss reserves on loans and financing receivables). However, the ultimate impact to our tenants’ results of operations and liquidity and their ability to pay our rent and interest due to the impact of COVID-19 cannot be predicted with 100% confidence, particularly given the full scope, severity, and duration of the pandemic and the actions needed (including vaccine rollouts worldwide) to contain the pandemic or mitigate its impact is uncertain. This makes any estimates and assumptions as of December 31, 2020 inherently less certain than they would be absent the potential impact of COVID-19. Actual results could differ from those estimates.

Principles of Consolidation

Principles of Consolidation: Property holding entities and other subsidiaries of which we own 100% of the equity or have a controlling financial interest evidenced by ownership of a majority voting interest are consolidated. All inter-company balances and transactions are eliminated. For entities in which we own less than 100% of the equity interest, we consolidate the property if we have the direct or indirect ability to control the entities’ activities based upon the terms of the respective entities’ ownership agreements. For these entities, we record a non-controlling interest representing equity held by non-controlling interests.

We continually evaluate all of our transactions and investments to determine if they represent variable interests in a variable interest entity. If we determine that we have a variable interest in a variable interest entity, we then evaluate if we are the primary beneficiary of the variable interest entity. The evaluation is a qualitative assessment as to whether we have the ability to direct the activities of a variable interest entity that most significantly impact the entity’s economic performance. We consolidate each variable interest entity in which we, by virtue of or transactions with our investments in the entity, are considered to be the primary beneficiary.

At December 31, 2020, we had loans and/or equity investments in certain variable interest entities approximating $230 million, which represents our maximum exposure to loss as a result of our involvement in such entities. We have determined that we were not the primary beneficiary of any variable interest entity in which we hold a variable interest because we do not control the activities (such as the day-to-day operations) that most significantly impact the economic performance of these entities.

Investments in Unconsolidated Entities

Investments in Unconsolidated Entities: Investments in entities in which we have the ability to significantly influence (but not control) are accounted for by the equity method, such as our joint venture with Primotop Holdings S.à.r.l. (“Primotop”) as discussed in Note 3. Under the equity method of accounting, our share of the investee’s earnings or losses are included in the “Earnings from equity interests” line of our consolidated statements of net income. Except for our joint venture with Primotop, we have elected to record our share of such investee’s earnings or losses on a lag basis. The initial carrying value of investments in unconsolidated entities is based on the amount paid to purchase the interest in the investee entity. Subsequently, our investments are increased/decreased by our share in the investees’ earnings/losses and decreased by cash distributions from our investees. To the extent that our cost basis is different from the basis reflected at the investee entity level, the basis difference is generally amortized over the lives of the related assets and liabilities, and such amortization is included in our share of equity in earnings of the investee.

We evaluate our equity method investments for impairment based upon a comparison of the fair value of the equity method investment to its carrying value, when impairment indicators exist. If we determine a decline in the fair value of an investment in an unconsolidated investee entity below its carrying value is other-than-temporary, an impairment is recorded.

Investments in entities in which we do not control nor do we have the ability to significantly influence and for which there is no readily determinable fair value (such as our investments in Steward Health Care System LLC (“Steward”) and Median Kliniken S.á.r.l. (“MEDIAN”)) are accounted for at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions involving the investee. Any cash distributions on these types of investments are recorded to income upon receipt. For similar investments but for which there are readily determinable fair values, such investments are measured at fair value, with unrealized gains and losses recorded in income.

Cash and Cash Equivalents

Cash and Cash Equivalents: Certificates of deposit, short-term investments with original maturities of three months or less, and money-market mutual funds are considered cash equivalents. The majority of our cash and cash equivalents are held at major commercial banks, which at times may exceed the Federal Deposit Insurance Corporation limit. We have not experienced any losses to-date on our invested cash. Cash and cash equivalents which have been restricted as to its use are recorded in other assets.

Revenue Recognition

Revenue Recognition: Our revenues are primarily from leases and loans. On January 1, 2019, we adopted Accounting Standards Update (“ASU”) 2016-02, “Leases”, (“ASU 2016-02”). ASU 2016-02 sets out the principles for the recognition, measurement, presentation, and disclosure of leases for both parties to a contract (i.e. lessees and lessors). We adopted this standard using the modified retrospective approach and elected the package of practical expedients permitted under the transition guidance within the new standard, which among other things permitted the following: no reassessment of whether existing contracts were or contained a lease and no reassessment of lease classification for existing leases. In addition, we made certain elections permitted which (1) allowed entities to apply the transition provisions of the new standard at its adoption date instead of at the earliest comparative period presented and (2) permitted lessors to account for lease and non-lease components as a single lease component in a contract if certain criteria were met. For lessors, this new standard of accounting for leases was substantially equivalent to previous guidance, but there were some differences which we highlight below:

Operating Lease Revenue

We receive income from operating leases based on the fixed required rents (base rents) per the lease agreements. Rent revenue from base rents is recorded on the straight-line method over the terms of the related lease agreements for new leases and the remaining terms of existing leases for those acquired as part of a property acquisition. The straight-line method records the periodic average amount of base rents earned over the term of a lease, taking into account contractual rent increases over the lease term. The straight-line method typically has the effect of recording more rent revenue from a lease than a tenant is required to pay early in the term of the lease. During the later parts of a lease term, this effect reverses with less rent revenue recorded than a tenant is required to pay. Rent revenue, as recorded on the straight-line method, in the consolidated statements of net income is presented as two amounts: rent billed and straight-line rent. Rent billed revenue is the amount of base rent actually billed to our tenants each period as required by the lease. Straight-line rent revenue is the difference between rent revenue earned based on the straight-line method and the amount recorded as rent billed revenue. We record the difference between rent revenues earned and amounts due per the respective lease agreements, as applicable, as an increase or decrease to straight-line rent receivables.

Rental payments received prior to their recognition as income are classified as deferred revenue.

Financing Lease Revenue

Under the lease accounting rules adopted on January 1, 2019, if an acquisition and subsequent lease of a property to the seller does not meet the definition of a sale, we must account for the transaction as a financing with income recognized using the imputed interest method.

Another type of financing lease that we carried forward from the previous lease accounting guidance is a direct financing lease (“DFL”). For leases accounted for as DFLs, the future minimum lease payments are recorded as a receivable. The difference between the future minimum lease payments and the estimated residual values less the cost of the properties is recorded as unearned income. Unearned income is deferred and amortized to income over the lease terms to provide a constant yield when collectability of the lease payments is reasonably assured. Investments in DFLs are presented net of unearned income.

Other Leasing Revenue

We begin recording base rent income from our development projects when the lessee takes physical possession of the facility, which may be different from the stated start date of the lease. Also, during construction of our development projects, we may be entitled to accrue rent based on the cost paid during the construction period (construction period rent). We accrue construction period rent as a receivable with a corresponding offset to deferred revenue during the construction period. When the lessee takes physical possession of the facility, we begin recognizing the deferred construction period revenue on the straight-line method over the term of the lease.

We also receive additional rent (contingent rent) under some leases based on increases in the consumer price index (“CPI”) (or similar index outside the U.S.) or when CPI exceeds the annual minimum percentage increase as stipulated in the lease. Contingent rents are recorded as rent billed revenue in the period earned.

Starting January 1, 2019 (with the adoption of ASU 2016-02), tenant payments for ground leases along with other operating expenses, such as property taxes and insurance, that are paid directly by us and reimbursed by our tenants are presented on a gross basis with the related revenues recorded in “Interest and other income” and the related expenses in “Property-related” in our consolidated statements of net income. All payments of other operating expenses made directly by the tenant to the applicable government or appropriate third-party vendor are recorded on a net basis, consistent with how all tenant payments or reimbursements pursuant to our “triple-net” leases were accounted for prior to the adoption of ASU 2016-02.

Interest Revenue

We receive interest income from our tenants/borrowers on mortgage loans, working capital loans, and other long-term loans. Interest income from these loans is recognized as earned based upon the principal outstanding and terms of the loans.

Other Revenue

Commitment fees received from lessees for development and leasing services are initially recorded as deferred revenue and recognized as income over the initial term of a lease to produce a constant effective yield on the lease (interest method). Commitment and origination fees from lending services are also recorded as deferred revenue initially and recognized as income over the life of the loan using the interest method.

Acquired Real Estate Purchase Price Allocation

Acquired Real Estate Purchase Price Allocation: We account for acquisitions of real estate under asset acquisition accounting rules. Under this accounting standard, we allocate the purchase price (including any third-party transaction costs directly related to the acquisition) of acquired properties to tangible and identified intangible assets acquired and liabilities assumed (if any) based on their fair values. In making estimates of fair values for purposes of allocating purchase prices of acquired real estate, we may utilize a number of sources, from time-to-time, including available real estate broker data, independent appraisals that may be obtained in connection with the acquisition, internal data from previous acquisitions or developments, and other market data, including market comparables for significant assumptions such as market rental, capitalization, and discount rates. We also consider information obtained about each property as a result of our pre-acquisition due diligence, marketing, and leasing activities in estimating the fair value of the tangible and intangible assets acquired.

We measure the aggregate value of lease intangible assets acquired based on the difference between (i) the property valued with new or in-place leases adjusted to market rental rates and (ii) the property valued as if vacant. Management’s estimates of value are made using methods similar to those used by independent appraisers (e.g., discounted cash flow analysis). Factors considered by management in our analysis include an estimate of carrying costs during hypothetical expected lease-up periods, considering current market conditions, and costs to execute similar leases. We also consider information obtained about each targeted facility as a result of

our pre-acquisition due diligence, marketing, and leasing activities in estimating the fair value of the intangible assets acquired. In estimating carrying costs, management includes real estate taxes, insurance, and other operating expenses and estimates of lost rentals at market rates during the expected lease-up periods, which we expect to be about six months, but can be longer depending on specific local market conditions. Management also estimates costs to execute similar leases including leasing commissions, legal costs, and other related expenses to the extent that such costs are not already incurred in connection with a new lease origination as part of the transaction.

Other intangible assets acquired may include customer relationship intangible values which are based on management’s evaluation of the specific characteristics of each prospective tenant’s lease and our overall relationship with that tenant. Characteristics to be considered by management in allocating these values include the nature and extent of our existing business relationships with the tenant, growth prospects for developing new business with the tenant, the tenant’s credit quality, and expectations of lease renewals, including those existing under the terms of the lease agreement, among other factors.

We amortize the value of our lease intangible assets to expense over the term of the respective leases. If a lease is terminated early, the unamortized portion of the lease intangibles are charged to expense.

We record above-market and below-market in-place lease values, if any, for our facilities, which are based on the present value of the difference between (i) the contractual amounts to be paid pursuant to the in-place leases and (ii) management’s estimate of fair market lease rates for the corresponding in-place leases, measured over a period equal to the remaining non-cancelable term of the lease. We amortize any resulting capitalized above-market lease values as a reduction of rental income over the lease term. We amortize any resulting capitalized below-market lease values as an increase to rental income over the lease term. If a lease is terminated early, the unamortized portion of the capitalized above/below market lease value is recognized in rental income at that time.

Real Estate and Depreciation

Real Estate and Depreciation: Real estate, consisting of land, buildings and improvements, are maintained at cost. Although typically paid by our tenants, any expenditure for ordinary maintenance and repairs that we pay are expensed to operations as incurred. Significant renovations and improvements which improve and/or extend the useful life of the asset are capitalized and depreciated over their estimated useful lives. We record impairment losses on long-lived assets used in operations when events and circumstances indicate that the assets might be impaired and the undiscounted cash flows estimated to be generated by those assets, including an estimated liquidation amount, during the expected holding periods are less than the carrying amounts of those assets. Impairment losses are measured as the difference between carrying value and fair value of the assets. For assets held for sale, we cease recording depreciation expense and adjust the assets’ value to the lower of its carrying value or fair value, less cost of disposal. Fair value is based on estimated cash flows discounted at a risk-adjusted rate of interest. We classify real estate assets as held for sale when we have commenced an active program to sell the assets, and in the opinion of management, it is probable the asset will be sold within the next 12 months.

Construction in progress includes the cost of land, the cost of construction of buildings, improvements, and fixed equipment, and costs for design and engineering. Other costs, such as interest, legal, property taxes, and corporate project supervision, which can be directly associated with the project during construction, are also included in construction in progress. We commence capitalization of costs associated with a development project when the development of the future asset is probable and activities necessary to get the underlying property ready for its intended use have been initiated. We stop the capitalization of costs when the property is substantially complete and ready for its intended use.

Depreciation is calculated on the straight-line method over the estimated useful lives of the related real estate and other assets. Our weighted-average useful lives at December 31, 2020 are as follows:

Buildings and improvements		39.0 years
Lease intangibles		26.1 years
Leasehold improvements		17.0 years
Furniture, equipment, and other		9.8 years

Losses from Rent Receivables

Credit Losses:

Losses from Rent Receivables: For all leases, we continuously monitor the performance of our existing tenants including, but not limited to: admission levels and surgery/procedure volumes by type; current operating margins; ratio of our tenants’ operating margins both to facility rent and to facility rent plus other fixed costs; trends in cash collections; trends in revenue and patient mix; and the effect of evolving healthcare regulations, adverse economic and political conditions, and other events ongoing (such as the recent health crisis caused by the COVID-19 pandemic) on tenants’ profitability and liquidity.

Losses from Operating Lease Receivables: We utilize the information above along with the tenant’s payment and default history in evaluating (on a property-by-property basis) whether or not a provision for losses on outstanding billed rent

and/or straight-line rent receivables is needed. A provision for losses on rent receivables (including straight-line rent receivables) is ultimately recorded when it becomes probable that the receivable will not be collected in full. The provision is an amount which reduces the receivable to its estimated net realizable value based on a determination of the eventual amounts to be collected either from the debtor or from existing collateral, if any.

Losses on Financing Lease Receivables: Upon the adoption of ASU No. 2016-13 “Measurement of Credit Losses on Financial Instruments" ("ASU 2016-13") on January 1, 2020, we began applying a new forward-looking “expected loss” model to all of our financing receivables, including financing leases and loans. With this change, we have grouped our financial instruments into two primary pools of similar credit risk: secured and unsecured. The secured instruments include our investments in financing receivables as all are secured by the underlying real estate among other collateral. Within the two primary pools, we further grouped our instruments into sub-pools based on several tenant/borrower characteristics, including years of experience in the healthcare industry and in a particular market or region and overall capitalization. We then determined a credit loss percentage per pool based on our history over a period of time that closely matches the remaining terms of the financial instruments being analyzed and adjusted as needed for current trends or unusual circumstances. We have applied these credit loss percentages to the book value of the related instruments to establish a credit loss reserve on our financing lease receivables and such credit loss reserve (including the underlying assumptions) is reviewed and adjusted quarterly. If a financing receivable is under performing and is deemed uncollectible based on the lessee’s overall financial condition, we will adjust the credit loss reserve based on the fair value of the underlying collateral.

With the adoption of ASU 2016-13, we made the accounting policy election to exclude interest receivables from the credit loss reserve analysis. Such receivables are impaired and an allowance recorded when it is deemed probable that we will be unable to collect all amounts due. Like operating lease receivables, the need for an allowance is based upon our assessment of the lessee’s overall financial condition, economic resources and payment record, the prospects for support from any financially responsible guarantors, and, if appropriate, the realizable value of any collateral. Financing leases are placed on non-accrual status when we determine that the collectability of contractual amounts is not reasonably assured. If on non-accrual status, we generally account for the financing lease on a cash basis, in which income is recognized only upon receipt of cash.

Loans

Loans: Loans consist of mortgage loans, working capital loans, and other loans. Mortgage loans are collateralized by interests in real property. Working capital and other loans are generally collateralized by interests in receivables and corporate and individual guarantees. We record loans at cost. Like our financing lease receivables, we are using ASU 2016-13 to establish credit loss reserves on all outstanding loans based on historical credit losses on similar instruments. Such credit loss reserves, including the underlying assumptions, are reviewed and adjusted quarterly. If a loan’s performance worsens and foreclosure is deemed probable for our collateral-based loans (after considering the borrower’s overall financial condition as described above for leases), we will adjust the allowance for expected credit losses based on the current fair value of such collateral at the time the loan is deemed uncollectible. If the loan is not collateralized, the loan will be written-off once it is determined that such loan is no longer collectible. Interest receivables on loans are excluded from ASU 2016-13 and we assess their collectability similar to how we assess collectability for interest receivables on financing leases described above.

Upon adoption of ASU 2016-13, we recorded a credit loss reserve of $8.4 million with the effect recorded in equity as a cumulative effect of a change in accounting principle.

Earnings Per Share/Units

Earnings Per Share/Units: Basic earnings per common share/unit is computed by dividing net income by the weighted-average number of shares/units outstanding during the period. Diluted earnings per common share/unit is calculated by including the effect of dilutive securities.

Our unvested restricted stock awards contain non-forfeitable rights to dividends, and accordingly, these awards are deemed to be participating securities. These participating securities are included in the earnings allocation in computing both basic and diluted earnings per common share/unit.

Income Taxes

Income Taxes: We conduct our business as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (“the Code”). To qualify as a REIT, we must meet certain organizational and operational requirements, including a requirement to distribute to stockholders at least 90% of our REIT’s ordinary taxable income. As a REIT, we generally pay little U.S. federal and state income tax because of the dividends paid deduction that we are allowed to take. If we fail to qualify as a REIT in any taxable year, we will then be subject to U.S. federal income taxes on our taxable income at regular corporate rates and will not be permitted to qualify for treatment as a REIT for federal income tax purposes for four years following the year during which qualification is lost, unless the Internal Revenue Service grants us relief under certain statutory provisions. Such an event could materially adversely affect our net income and net cash available for distribution to stockholders. However, we intend to operate in such a manner so that we will remain qualified as a REIT for U.S. federal income tax purposes.

Our financial statements include the operations of a TRS, MPT Development Services, Inc. (“MDS”), and with many other entities, which are single member LLCs that are disregarded for tax purposes and are reflected in the tax returns of MDS. MDS is not

entitled to a dividends paid deduction and is subject to U.S. federal, state, and local income taxes. MDS is authorized to provide property development, leasing, and management services for third-party owned properties, and we will make non-mortgage loans to and/or investments in our lessees through this entity.

With the property acquisitions and investments in Europe, Australia, and South America, we are subject to income taxes internationally. However, we do not expect to incur any additional income taxes in the U.S. as such income from our international properties flows through our REIT income tax returns. For our TRS and international subsidiaries, 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 our deferred tax assets/liabilities that results from a change in circumstances and that causes us to change our judgment about expected future tax consequences of events, is reflected in our tax provision when such changes occur. Deferred income taxes also reflect the impact of operating loss carryforwards. A valuation allowance is provided if we believe it is more likely than not that all or some portion of our deferred tax assets 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 our ability to realize the related deferred tax asset, is reflected in our tax provision when such changes occur.

The calculation of our income taxes involves dealing with uncertainties in the application of complex tax laws and regulations in a multitude of jurisdictions across our global operations. An income tax benefit from an uncertain tax position may be recognized when it is more likely than not that the position will be sustained upon examination, including resolutions of any related appeals or litigation processes, on the basis of technical merits. However, if a more likely than not position cannot be reached, we record a liability as an offset to the tax benefit and adjust the liabilities when our judgment changes as a result of the evaluation of new information not previously available. Because of the complexity of some of these uncertainties, the ultimate resolution may result in a payment that is materially different from our current estimate of the uncertain tax position liabilities. These differences will be reflected as increases or decreases to income tax expense in the period in which new information is available.

Stock-Based Compensation

Stock-Based Compensation: We adopted the 2019 Equity Incentive Plan (the “Equity Incentive Plan”) during the second quarter of 2019. Awards of restricted stock and other equity-based awards with service conditions are valued at the average stock price per share on the date of grant and are amortized to compensation expense over the service periods (typically three years), using the straight-line method. Awards that contain market conditions are valued on the grant date using a Monte Carlo valuation model and are amortized to compensation expense over the derived service periods, which correspond to the periods over which we estimate the awards will be earned, which generally range from three to five years, using the straight-line method. Awards with performance conditions are valued at the average stock price per share on the date of grant and are amortized using the straight-line method over the service period, adjusted for the probability of achieving the performance conditions. Forfeitures of stock-based awards are recognized as they occur.

Deferred Costs

Deferred Costs: Costs incurred that directly relate to the offerings of stock are deferred and netted against proceeds received from the offering. Leasing commissions and other leasing costs that would not have been incurred if the lease was not obtained are capitalized as deferred leasing costs and amortized on the straight-line method over the terms of the related lease agreements. Costs identifiable with loans made to borrowers are capitalized and recognized as a reduction in interest income over the life of the loan.

Deferred Financing Costs

Deferred Financing Costs: We generally capitalize financing costs incurred in connection with new financings and refinancings of debt. These costs are amortized over the lives of the related debt as an addition to interest expense. For debt with defined principal re-payment terms, the deferred costs are amortized to produce a constant effective yield on the debt (interest method) and are included within “Debt, net” on our consolidated balance sheets. For debt without defined principal repayment terms, such as our revolving credit facility, the deferred costs are amortized on the straight-line method over the term of the debt and are included as a component of “Other assets” on our consolidated balance sheets.

Foreign Currency Translation and Transactions

Foreign Currency Translation and Transactions: Certain of our international subsidiaries’ functional currencies are the local currencies of their respective countries. We translate the results of operations of our foreign subsidiaries into U.S. dollars using average rates of exchange in effect during the period, and we translate balance sheet accounts using exchange rates in effect at the end of the period. We record resulting currency translation adjustments in “Accumulated other comprehensive income (loss)”, a component of stockholders’ equity on our consolidated balance sheets.

Certain of our U.S. subsidiaries will enter into short-term and long-term transactions denominated in a foreign currency from time-to-time. Gains or losses resulting from these foreign currency transactions are revalued into U.S. dollars at the rates of exchange prevailing at the dates of the transactions. The effects of revaluation gains or losses on our short-term transactions are included in other income in the consolidated statements of income, while the revaluation effects on our long-term investments are recorded in “Accumulated other comprehensive income (loss)” on our consolidated balance sheets.

Derivative Financial Investments and Hedging Activities

Derivative Financial Investments and Hedging Activities: During our normal course of business, we may use certain types of derivative instruments for the purpose of managing interest rate and/or foreign currency risk. We record our derivative and hedging instruments at fair value on the balance sheet. Changes in the estimated fair value of derivative instruments that are not designated as

hedges or that do not meet the criteria for hedge accounting are recognized in earnings. For derivatives designated as cash flow hedges, the change in the estimated fair value of the effective portion of the derivative is recognized in “Accumulated other comprehensive income (loss)” on our consolidated balance sheets, whereas the change in the estimated fair value of the ineffective portion is recognized in earnings. For derivatives designated as fair value hedges, the change in the estimated fair value of the effective portion of the derivatives offsets the change in the estimated fair value of the hedged item, whereas the change in the estimated fair value of the ineffective portion is recognized in earnings.

To qualify for hedge accounting, we formally document all relationships between hedging instruments and hedged items, as well as our risk management objective and strategy for undertaking the hedge prior to entering into a derivative transaction. This process includes specific identification of the hedging instrument and the hedge transaction, the nature of the risk being hedged and how the hedging instrument’s effectiveness in hedging the exposure to the hedged transaction’s variability in cash flows attributable to the hedged risk will be assessed. Both at the inception of the hedge and on an ongoing basis, we assess whether the derivatives that are used in hedging transactions are highly effective in offsetting changes in cash flows or fair values of hedged items. In addition, for cash flow hedges, we assess whether the underlying forecasted transaction will occur. We discontinue hedge accounting if a derivative is not determined to be highly effective as a hedge or that it is probable that the underlying forecasted transaction will not occur.

Fair Value Measurement

Fair Value Measurement: We measure and disclose the estimated fair value of 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 our 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.

We measure fair value using a set of standardized procedures that are outlined herein for all assets and liabilities which are required to be measured at their estimated fair value on either a recurring or non-recurring basis. When available, we utilize quoted market prices from an independent third party source to determine fair value and classify 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, we apply the dealer (market maker) pricing estimate and classify the asset or liability 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, market capitalization rates, etc. 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, the asset or liability could be classified in either Level 2 or 3 even though there may be some significant inputs that are readily observable. Internal fair value models and techniques that have been used by us include discounted cash flow and Monte Carlo valuation models. We also consider counterparty’s and our own credit risk on derivatives and other liabilities measured at their estimated fair value.

Fair Value Option Election: For our equity investment in the new international joint venture along with any related investments such as loans (see Note 3 for more details), we have elected to account for these investments at fair value due to the size of the investments and because we believe this method is more reflective of current values. We have not made a similar election for other investments that existed at December 31, 2020.

Leases (Lessee)

Pursuant to ASU 2016-02, we are required to apply a dual approach, classifying leases as either financing or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification determines whether lease expense is recognized based on an effective interest method (for finance leases) or on a straight-line basis (for operating leases) over the term of the lease. Starting January 1, 2019, we began recording a right-of-use asset and a lease liability for all material leases with a term greater than 12 months regardless of their classification. Leases with a term of 12 months or less are off balance sheet with lease expense recognized on a straight-line basis over the lease term, similar to previous guidance for operating leases.

Reclassification

Reclassifications: Certain amounts in the consolidated financial statements for prior periods have been reclassified to conform to the current period presentation.

Recent Accounting Developments

Reference Rate Reform

In March 2020, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2020-04, “Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting” (“ASU 2020-04”) to simplify the accounting for contract modifications made to replace LIBOR or other reference rates that are expected to be discontinued because of reference rate reform. The guidance provides optional expedients and exceptions for applying U.S. GAAP to contracts, hedging relationships, and other transactions affected by reference rate reform if certain criterion are met. The optional expedients and exceptions can be applied to contract modifications made until December 31, 2022. On January 7, 2021, the FASB issued ASU No. 2021-01, “Reference Rate Reform (Topic 848)” (“ASU 2021-01”), which clarifies that certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that are affected by the discounting transition. The amendments in ASU 2021-01 are elective and apply to our debt and derivative instruments that may be modified as a result of reference rate reform. We are continuing to evaluate these standards, as well as the timing of the transition of various rates in our debt and derivative instruments affected by reference rate reform.

Stock Awards

Our Equity Incentive Plan, adopted during the second quarter of 2019 and replaced the previous plan, authorizes the issuance of common stock options, restricted stock, restricted stock units, deferred stock units, stock appreciation rights, performance units, and awards of interests in our Operating Partnership. Our Equity Incentive Plan is administered by the Compensation Committee of the Board of Directors. We have reserved 12.9 million shares of new common stock for awards under the Equity Incentive Plan, out of which 8.4 million shares remain available for future stock awards as of December 31, 2020. The Equity Incentive Plan contains a limit of 5 million shares as the maximum number of shares of common stock that may be awarded to an individual in any fiscal year. Awards under the Equity Incentive Plan are subject to forfeiture due to termination of employment prior to vesting and/or from not achieving the respective performance/market conditions. In the event of a change in control, outstanding and unvested options will immediately vest, unless otherwise provided in the participant’s award or employment agreement, and restricted stock, restricted stock units, deferred stock units, and other stock-based awards will vest if so provided in the participant’s award agreement. The term of the awards is set by the Compensation Committee, though Incentive Stock Options may not have terms of more than ten years. Forfeited awards are returned to the Equity Incentive Plan and are then available to be re-issued as future awards. For each share of common stock issued by Medical Properties Trust, Inc. pursuant to its Equity Incentive Plan, the Operating Partnership issues a corresponding number of Operating Partnership units.

For the past three years, we have only granted restricted stock and restricted stock units pursuant to our Equity Incentive Plan. These stock-based awards have been granted in the form of service-based awards and performance awards based on company-specific performance hurdles. See below for further details on each of these stock-based awards:

Service-Based Awards

In 2020, 2019, and 2018, the Compensation Committee granted service-based awards to employees and non-employee directors. Service-based awards vest as the employee/director provides the required service (typically over three years). Dividends are generally paid on these awards prior to vesting.

Performance-Based Awards

In 2020, 2019, and 2018, the Compensation Committee granted performance-based awards to employees. Generally, dividends are not paid on performance awards until the award is earned. See below for details of such performance-based award grants:

In 2020, 2019, and 2018, a target number of stock awards were granted to employees that could be earned based on the achievement of specific performance thresholds as set by our Compensation Committee. The performance thresholds were based on a three-year period with the opportunity to earn a portion of the award earlier. More or less shares than the target number of shares are available to be earned based on our performance compared to the set thresholds. At the end of each of the performance periods, any earned shares during such period will vest on January 1 of the following calendar year. The performance thresholds for 2020 awards were based on funds from operations growth, EBITDA, and acquisitions; whereas, the 2019 and 2018 performance thresholds were based on return on equity, EBITDA, and acquisitions.

Certain performance awards granted were subject to a modifier which increases or decreases the actual shares earned in each performance period. The modifier for the 2020 awards was based on two components: 1) how our total shareholder return (“TSR”) compared to the SNL U.S. REIT Healthcare Index (“SNL Index”) and 2) how our TSR compared to a threshold set by the Compensation Committee. For 2019 and 2018 awards, the modifier was based on how our TSR compared to the SNL Index.

The following summarizes stock-based award activity in 2020 and 2019 (which includes awards granted in 2020, 2019, 2018, and any applicable prior years), respectively:

Nonvested awards at end of year		1,122,440		$	17.11		5,481,155		$	11.66

The value of stock-based awards is charged to compensation expense over the service periods. For the years ended December 31, 2020, 2019, and 2018, we recorded $47.2 million, $32.2 million, and $16.5 million, respectively, of non-cash compensation expense. The remaining unrecognized cost from stock-based awards at December 31, 2020, is $53.6 million, which will be recognized over a weighted-average period of 1.3 years. Stock-based awards that vested in 2020, 2019, and 2018, had a value of $58.9 million, $25.9 million, and $8.4 million, respectively.

Equity Offering

On January 11, 2021, we completed an underwritten public offering of 36.8 million shares (including the exercise of the underwriters’ 30-day option to purchase an additional 4.8 million shares) of our common stock, resulting in net proceeds of approximately $711.0 million, after deducting underwriting discounts and commissions and offering expenses.

Credit Facility Amendment

On January 15, 2021, we amended our Credit Facility. The amendment extended the maturity of our revolving facility to February 2024 and can be extended for an additional 12 months at our option. The maturity date of our $200 million unsecured term loan facility was extended to February 1, 2026.

In addition to extending the maturity date, the amendment improved interest rate pricing for both facilities. Under the amended Credit Facility and at our election, loans may be made as either ABR Loans or Eurocurrency Loans. The applicable margin for term loans that are ABR Loans is adjustable on a sliding scale from 0.00% to 0.85% based on our current credit rating. The applicable margin for term loans that are Eurocurrency Loans is adjustable on a sliding scale from 0.85% to 1.85% based on our current credit rating. The applicable margin for revolving loans that are ABR Loans is adjustable on a sliding scale from 0.00% to 0.55% based on our current credit rating. The applicable margin for revolving loans that are Eurocurrency Loans is adjustable on a sliding scale from 0.825% to 1.55% based on our current credit rating. The amended Credit Facility retained the facility fee that is adjustable on a sliding scale from 0.125% to 0.30% based on our current credit rating and is payable on the revolving loan facility.

Fair Value of Financial Instruments

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

10. Fair Value of Financial Instruments

We have various assets and liabilities that are considered financial instruments. We estimate that the carrying value of cash and cash equivalents and accounts payable and accrued expenses approximate their fair values. We estimate the fair value of our interest and rent receivables using Level 2 inputs such as discounting the estimated future cash flows using the current rates at which similar receivables would be made to others with similar credit ratings and for the same remaining maturities. The fair value of our mortgage loans and other loans are estimated by using Level 2 inputs such as discounting the estimated future cash flows using the current rates which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities. We determine the fair value of our senior unsecured notes using Level 2 inputs such as quotes from securities dealers and market makers. We estimate the fair value of our revolving credit facility and term loans using Level 2 inputs based on the present value of future payments, discounted at a rate which we consider appropriate for such debt.

Fair value estimates are made at a specific point in time, are subjective in nature, and involve uncertainties and matters of significant judgment. Settlement of such fair value amounts may not be a prudent management decision.

The following table summarizes fair value estimates for our financial instruments (in thousands):

	December 31, 2020						December 31, 2019
Asset (Liability)	Book Value			Fair Value			Book Value			Fair Value
Interest and rent receivables	$	46,208		$	45,381		$	31,357		$	30,472

(1)	Excludes the $205 million acquisition loan to the new international joint venture and investment in the real estate of three hospitals in Colombia discussed in Note 3 as they are recorded at fair value and discussed below.

Items Measured at Fair Value on a Recurring Basis

Our equity investment and related loan to the new international joint venture and our loan investment in the real estate of three hospitals operated by subsidiaries of the international joint venture in Colombia are measured at fair value on a recurring basis as we elected to account for these investments using the fair value option at the point of initial investment during 2020. Our Ernest mortgage loans were measured at fair value on a recurring basis in prior periods as we elected to account for these investments using the fair value option method in 2012 when we acquired an equity interest in Ernest. Such equity interest was sold in October 2018, and the mortgage loans were converted to fee simple real estate on December 31, 2020 as discussed in Note 3. We elected to account for each of these investments at fair value due to the size of the investments and because we believe this method was more reflected of current values.

At December 31, 2020 and 2019, the amounts recorded under the fair value option method were as follows (in thousands):

	As of December 31, 2020				As of December 31, 2019
Asset (Liability)	Fair Value		Original Cost		Fair Value		Original Cost		Asset Type Classification
Mortgage loans	$	136,332	$	136,332	$	115,000	$	115,000	Mortgage loans
Equity investment and other loans		218,775		218,775		—		—	Equity investments/Other loans

Our loans to the new international joint venture and its subsidiaries are recorded at fair value based on Level 2 inputs by discounting the estimated cash flows using the market rates which similar loans would be made to borrowers with similar credit ratings and the same remaining maturities. Our equity investment in the international joint venture is recorded at fair value based on Level 3 inputs, by using a discounted cash flow model, which requires significant estimates of our investee such as projected revenue and expenses and appropriate consideration of the underlying risk profile of the forecasted assumptions associated with the investee. We classify the equity investment as Level 3, as we use certain unobservable inputs to the valuation methodology that are significant to the fair value measurement, and the valuation requires management judgment due to absence of quoted market prices. For this cash flow model, our observable inputs include use of a capitalization rate and discount rate (which is based on a weighted-average cost of capital) and our unobservable input includes an adjustment for a marketability discount (“DLOM”).

In regards to the underlying projections used in the discounted cash flow model, such projections are provided by the investee. However, we will modify such projections as needed based on our review and analysis of historical results, meetings with key members of management, and our understanding of trends and developments within the healthcare industry. Given our equity investment is in an entity that was a start-up company in 2020, we have not recognized any unrealized gain/loss on such investment in 2020.

Items Measured at Fair Value on a Nonrecurring Basis

In addition to items that are measured at fair value on a recurring basis, we have assets and liabilities that are measured at fair value on a nonrecurring basis, such as long-lived asset impairments (see Note 3). Fair value is based on estimated cash flows discounted at a risk-adjusted rate of interest by using either Level 2 or 3 inputs as more fully described in Note 2.

- Definition

The entire disclosure for the fair value of financial instruments (as defined), including financial assets and financial liabilities (collectively, as defined), and the measurements of those instruments as well as disclosures related to the fair value of non-financial assets and liabilities. Such disclosures about the financial instruments, assets, and liabilities would include: (1) the fair value of the required items together with their carrying amounts (as appropriate); (2) for items for which it is not practicable to estimate fair value, disclosure would include: (a) information pertinent to estimating fair value (including, carrying amount, effective interest rate, and maturity, and (b) the reasons why it is not practicable to estimate fair value; (3) significant concentrations of credit risk including: (a) information about the activity, region, or economic characteristics identifying a concentration, (b) the maximum amount of loss the entity is exposed to based on the gross fair value of the related item, (c) policy for requiring collateral or other security and information as to accessing such collateral or security, and (d) the nature and brief description of such collateral or security; (4) quantitative information about market risks and how such risks are managed; (5) for items measured on both a recurring and nonrecurring basis information regarding the inputs used to develop the fair value measurement; and (6) for items presented in the financial statement for which fair value measurement is elected: (a) information necessary to understand the reasons for the election, (b) discussion of the effect of fair value changes on earnings, (c) a description of [similar groups] items for which the election is made and the relation thereof to the balance sheet, the aggregate carrying value of items included in the balance sheet that are not eligible for the election; (7) all other required (as defined) and desired information.

We have operated as a real estate investment trust (“REIT”) since April 6, 2004, and accordingly, elected REIT status upon the filing in September 2005 of the calendar year 2004 federal income tax return. Accordingly, we will generally not be subject to United States (“U.S.”) federal income tax, provided that we continue to qualify as a REIT and our distributions to our stockholders equal or exceed our taxable income. Certain non-real estate activities we undertake are conducted by entities which we elected to be treated as taxable REIT subsidiaries (“TRS”). Our TRS entities are subject to both U.S. federal and state income taxes. For our properties located outside the U.S., we are subject to the local taxes of the jurisdictions where our properties reside and/or legal entities are domiciled; however, we do not expect to incur substantial additional taxes in the U.S. from foreign based income as the majority of such income flows through our REIT.

Our primary business strategy is to acquire and develop real estate and improvements, primarily for long-term lease to providers of healthcare services, such as operators of general acute care hospitals, inpatient physical rehabilitation hospitals, long-term acute care hospitals, freestanding ER/urgent care facilities, and behavioral health facilities. We also make mortgage and other loans to operators of similar facilities. In addition, we may obtain profits or equity interests in our tenants, from time-to-time, in order to enhance our overall return.

Our business model facilitates acquisitions and recapitalizations, and allows operators of healthcare facilities to unlock the value of their real estate to fund facility improvements, technology upgrades, and other investments in operations. At December 31, 2020, we have investments in 392 facilities in 33 states in the U.S., in six countries in Europe, one country in South America, and across Australia. We manage our business as a single business segment.

2020 Activity

Circle Transaction

On January 8, 2020, we acquired a portfolio of 30 acute care hospitals located throughout the United Kingdom for a net purchase price of approximately £1.5 billion from affiliates of BMI Healthcare, Inc. (“BMI”), as part of a share purchase in which we also inherited certain deferred income tax liabilities and £27.6 million of unearned rent revenue. In a related transaction, affiliates of Circle Health Ltd. (“Circle”) entered into definitive agreements to acquire BMI and assume operations of its 52 facilities in the United Kingdom. As part of our acquisition, we inherited 30 existing leases with the operator that had initial fixed terms ending in 2050, with no renewal options but with annual inflation-based escalators. Once final regulatory approval was received in the 2020 second quarter, these 30 leases with Circle were amended (effective June 16, 2020) to include two five-year renewal options and improve the annual inflation-based escalators. These 30 leases are cross-defaulted and guaranteed by Circle.

Other Transactions

On December 31, 2020, we acquired an inpatient rehabilitation hospital in South Carolina for approximately $17 million. As part of the transaction, we acquired the fee simple real estate of three inpatient rehabilitation hospitals and one long-term acute care hospital in exchange for the reduction of the mortgage loans made to Ernest for such properties in 2012. The approximate $115 million investment in all five of these facilities is leased to Ernest pursuant to an existing long-term master lease that has an initial term ending in December 2037 with multiple extension options and annual escalation provisions.

On December 29, 2020, we increased our equity ownership and related investment in Infracore SA (“Infracore”) by investing an additional CHF 206.5 million. We are accounting for our total investment in this joint venture (this investment along with our initial investment in 2019 as noted below) under the equity method.

On November 17, 2020, we invested in the real estate of three general acute care hospitals in Colombia for approximately $135 million. These properties will be operated by the new international joint venture discussed below.

On August 13, 2020, we acquired a general acute care hospital in Lynwood, California for a total investment of approximately $300 million. This property is leased to Prime Healthcare Services, Inc. (“Prime”), pursuant to an existing long-term master lease, which we extended its initial fixed term to August 2035 in connection with this transaction, with annual escalations and multiple extension options.

On July 8, 2020, we acquired the fee simple real estate of two general acute care hospitals located in the Salt Lake City, Utah area, Davis Hospital & Medical Center and Jordan Valley Medical Center, in exchange for the reduction of the mortgage loans made to Steward for such properties and additional cash consideration of $200 million based on their relative fair value. The approximate $950 million investment in these two facilities is now subject to the Steward master lease that has an initial fixed term ending in October 2031 with multiple extension options and annual escalation provisions.

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

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

Other acquisitions in 2020 included three inpatient rehabilitation hospitals, two general acute care hospitals, and one private acute care hospital totaling approximately $300 million. One inpatient rehabilitation facility, located in Dahlen, Germany, was acquired on August 5, 2020 for €12.5 million and is leased to MEDIAN Kliniken S.à.r.l. (“MEDIAN”) pursuant to the existing master lease. One of the general acute care facilities, located in Darlington, United Kingdom, was acquired on August 7, 2020 for £29.4 million and is leased to Circle pursuant to a long-term lease. The other general acute care hospital, located in London, United Kingdom, was acquired on November 25, 2020 for £50 million via the purchase of a 999-year ground lease and is leased to The Royal Marsden NHS Foundation Trust pursuant to a long-term lease. The inpatient rehabilitation hospitals, one in Texas and one in Indiana, were acquired on December 17, 2020 for approximately $58 million and are leased to Curahealth Hospitals pursuant to a long-term lease. The private acute care hospital, located in Reading, United Kingdom, was acquired on December 18, 2020 for £85.0 million and is leased to Circle pursuant to the existing long-term Circle master lease.

2019 Activity

LifePoint Acquisition

On December 17, 2019, we acquired a portfolio of 10 acute care hospitals owned and operated by LifePoint Health, Inc. (“LifePoint”) for a combined purchase price of approximately $700.0 million. The properties are leased to LifePoint under one master lease agreement. The master lease had a 20-year initial term and two five-year extension options, plus annual inflation-based escalators.

Prospect Transaction

On August 23, 2019, we invested in a portfolio of 14 acute care hospitals and two behavioral health facilities operated by Prospect Medical Holdings, Inc. (“Prospect”) for a combined purchase price of approximately $1.55 billion. Our investment included the acquisition of the real estate of 11 acute care hospitals and two behavioral health facilities for $1.4 billion. We are accounting for these properties as a financing (as presented in the “Investment in financing leases” line of the consolidated balance sheets) under lease accounting rules due to certain lessee end-of-term purchase options. In addition, we originated a $51.3 million mortgage loan, secured by a first mortgage on an acute care hospital, and a $112.9 million term loan which we expect will be converted into the acquisition of two additional acute care hospitals upon the satisfaction of certain conditions. The master leases and mortgage loan have substantially similar terms, with a 15-year fixed term subject to three extension options, plus annual inflation-based escalators.

The agreements provide for the potential for a future purchase price adjustment of up to an additional $250.0 million, based on achievement of certain performance thresholds over a three-year period beginning August 23, 2019. Although such performance thresholds have not been met at this time, any future purchase price adjustment will be added to the lease base upon which we will earn a return in accordance with the master leases.

Ramsay Acquisition

On August 16, 2019, we acquired freehold interests in eight acute care hospitals located throughout England for an aggregate purchase price of approximately £347 million. The hospitals are leased to Ramsay pursuant to in-place net leases with remaining lease terms ending in 2037 and include annual fixed and periodic market-based escalations.

Australia Transaction

On June 6, 2019, we acquired 11 hospitals in Australia for a purchase price of approximately A$1.2 billion plus stamp duties and registration fees of A$66.6 million. The properties are leased to Healthscope, pursuant to master lease agreements that had an average initial term of 20 years, upon our acquisition, with annual fixed escalations and multiple extension options. Healthscope was acquired in a simultaneous transaction by Brookfield Business Partners L.P. and certain of its institutional partners.

Switzerland Transactions

On May 27, 2019, we invested in a portfolio of 13 acute care campuses and two additional properties in Switzerland for an aggregate purchase price of approximately CHF 236.6 million. The investment (which we account for under the equity method) was effected through our purchase of a stake in a Swiss healthcare real estate company, Infracore, from the previous majority shareholder, Aevis Victoria SA (“Aevis”). The facilities are leased to Swiss Medical Network, a wholly-owned Aevis subsidiary, pursuant to leases that had an average 23-year remaining term upon our acquisition and are subject to annual escalation provisions. Additionally, we purchased a 4.9% stake in Aevis for approximately CHF 47 million on June 28, 2019 that we are marking to fair value through income.

Other Transactions

On December 3, 2019, we invested in two acute care hospitals in Spain for a purchase price of approximately €117.3 million. The investment was effected through our purchase of a 45% stake in a Spanish entity. The facilities are leased to HM Hospitales pursuant to a master lease that had an initial lease term of 25 years upon our investment. The lease provides for annual inflation-based escalators. We are accounting for our 45% interest in this joint venture under the equity method.

On November 28, 2019, we acquired an acute care hospital in Portugal for approximately €28.2 million. This facility is leased to José de Mello pursuant to an in-place lease with 17 years remaining on its initial term upon our acquisition. The lease provides for annual inflation-based escalators.

On August 30, 2019, we invested in a portfolio of facilities throughout various states for approximately $254 million. The properties are leased to Vibra Healthcare, LLC (“Vibra”) pursuant to a master lease agreement that had an initial lease term of 20 years upon acquisition. The lease provides for annual escalations and includes three five-year extension options.

On June 10, 2019, we acquired seven community hospitals in Kansas for approximately $145.4 million. The properties are leased to an affiliate of Saint Luke’s Health System (“SLHS”) pursuant to seven individual in-place leases that had an average remaining lease term of 14 years upon our acquisition. The leases provide for fixed escalations every five years and include two five-year extension options. All seven hospitals were constructed in either 2018 or 2019, and the leases are guaranteed by SLHS.

Other acquisitions during 2019 included three acute care hospitals and one inpatient rehabilitation hospital for an aggregate investment of approximately $135 million. One of the acute care hospitals, acquired on April 12, 2019 and located in Big Spring, Texas, is leased to Steward pursuant to the Steward master lease. The second facility, located in Poole, England, was acquired on April 3, 2019 and is leased to Circle. The third acute care facility was acquired on September 30, 2019 and located in Watsonville, California. The inpatient rehabilitation hospital, acquired on February 8, 2019, is located in Germany and leased to affiliates of MEDIAN.

2018 Activity

Joint Venture Transaction

On August 31, 2018, we completed a joint venture arrangement with Primotop pursuant to which we contributed 71 of our post-acute hospitals in Germany, with an aggregate fair value of €1.635 billion, for a 50% interest, while Primotop contributed cash for its 50% interest in the joint venture. As part of the transaction, we received an aggregate amount of approximately €1.14 billion, from the proceeds of the cash contributed by Primotop and the secured debt financing placed on the joint venture’s real estate, and we recognized an approximate €500 million gain on sale. At inception, our interest in the joint venture was made up of a 50% equity investment valued at approximately €210 million, which is being accounted for under the equity method of accounting, and a €290 million shareholder loan (with terms identical to Primotop’s shareholder loan).

Other Transactions

On August 31, 2018, we acquired an acute care facility in Pasco, Washington for $17.5 million. The property is leased to LifePoint, pursuant to the existing long-term master lease.

On August 28, 2018, we acquired three inpatient rehabilitation hospitals in Germany for €17.3 million (including real estate transfer taxes). Upon acquisition, the properties were leased to MEDIAN, pursuant to a 27-year master lease with annual inflation-based escalators.

During 2018, we acquired the fee simple real estate of five general acute care hospitals, four of which are located in Massachusetts and one located in Texas, from Steward in exchange for the reduction of $764.4 million of mortgage loans made to Steward in October 2016 and March 2018, along with additional cash consideration. These properties are being leased to Steward pursuant to the original master lease from October 2016.

On August 31, 2018, we completed the previously described joint venture arrangement with Primotop, in which we contributed the real estate of 71 of our post-acute hospitals in Germany, with a fair value of approximately €1.635 billion, resulting in a gain of approximately €500 million. See “New Investments” in this Note 3 for further details on this transaction.

On August 31, 2018, we sold a general acute care hospital located in Houston, Texas that was leased and operated by North Cypress for $148 million. The transaction resulted in a gain on sale of $102.4 million, which was partially offset by a net $2.5 million non-cash charge to revenue to write-off related straight-line rent receivables.

On June 4, 2018, we sold three long-term acute care hospitals located in California, Texas, and Oregon, that were leased and operated by Vibra, which included our equity investment in operations of the Texas facility. Total proceeds from the transaction were $53.3 million in cash, a mortgage loan in the amount of $18.3 million, and a $1.5 million working capital loan. The transaction resulted in a gain on real estate of $24.2 million, which was partially offset by a $5.1 million non-cash charge to revenue to write-off related straight-line rent receivables.

On March 1, 2018, we sold the real estate of St. Joseph Medical Center in Houston, Texas, for approximately $148 million to Steward. In return, we received a mortgage loan equal to the purchase price, with such loan secured by the underlying real estate. This transaction resulted in a gain of $1.5 million, offset by a $1.7 million non-cash charge to revenue to write-off related straight-line rent receivables on this property.

Leasing Operations (Lessor)

We acquire and develop healthcare facilities and lease the facilities to healthcare operating companies under long-term net leases (typical initial fixed terms of 15 years) and most include renewal options at the election of our tenants, generally in five year increments. Approximately 99% of our leases provide annual rent escalations based on increases in the CPI (or similar index outside the U.S.) and/or fixed minimum annual rent escalations ranging from 0.5% to 3.0%. Many of our domestic leases contain purchase options with pricing set at various terms but in no case less than our total investment. For five properties with a carrying value of $229 million, our leases require a residual value guarantee from the tenant. Our leases typically require the tenant to handle and bear most of the costs associated with our properties including repair/maintenance, property taxes, and insurance. We routinely inspect our properties to ensure the residual value of each of our assets is being maintained. Except for leases classified as financing leases as noted below, all of our leases are classified as operating leases.

	Total Under Operating Leases		Total Under Financing Leases		Total
2021	$	858,067	$	160,925	$	1,018,992
2022		875,350		164,144		1,039,494

	$	26,551,763	$	5,431,217	$	31,982,980

At December 31, 2020, leases on 13 Ernest facilities and five Prime facilities are accounted for as DFLs and leases on 13 of our Prospect facilities and five of our Ernest facilities are accounted for as a financing. The components of our total investment in financing leases consisted of the following (in thousands):

	As of December 31, 2020			As of December 31, 2019
Minimum lease payments receivable	$	1,228,966		$	1,884,921

Total investment in financing leases	$	2,010,922		$	2,060,302

Rent Deferrals

Due to the COVID-19 pandemic and its impact on our tenants’ business during 2020, we agreed to defer collection on less than 2% of our annual rent. The amount of this deferral, net of subsequent collections, is approximately $11.4 million as of December 31, 2020. Pursuant to our agreements with the tenants, we expect such deferred rent to be paid over specified periods in the future, with interest.

Adeptus Health

As discussed in previous filings, our original real estate portfolio of approximately 60 properties leased to Adeptus Health, Inc. (“Adeptus”) has gone through significant changes starting with Adeptus filing for Chapter 11 bankruptcy in 2017. With this filing and other subsequent events (including COVID-19 implications in 2020), we have transitioned all of the facilities away from Adeptus. These transition measures have resulted in impairment charges including approximately $20 million (of which one-half related to straight-line rent write-offs), $2 million, and $24 million (of which $6 million was straight-line rent write-offs) in 2020, 2019, and 2018, respectively. However, these transition measures have also provided for new tenant relationships being formed with strong credit worthy operators like Ochsner Health System, Dignity Health, UC Health, and HCA Healthcare (via a joint venture discussed below), that are now leasing approximately 40 of these transitional facilities under long-term leases. At December 31, 2020, 18 of these transitional properties, representing less than 1% of our total assets, remain vacant, and each of these properties are in various stages of being re-leased or sold. At December 31, 2020, we believe our investment in these real estate assets are fully recoverable, but no assurances can be given that we will not have any further impairments in future periods.

Alecto Facilities

As noted in previous filings, we originally leased four acute care facilities and had a mortgage loan on a fifth property (Olympia Medical Center) to Alecto Healthcare Services LLC (“Alecto”). During 2018 and 2019, we incurred approximately $30 million and $20 million in real estate impairment charges, respectively. During the second quarter of 2020, we re-leased one acute care facility to West Virginia University and sold another facility. We also donated the Wheeling facility to a local municipality, resulting in a $9.1 million real estate impairment charge in the first quarter of 2020. At December 31, 2020, we continue to lease one acute care facility to Alecto and have a mortgage loan on the second property, representing less than 0.5% of our total assets. Subsequent to year-end, Alecto completed the sale of Olympia Medical Center to the UCLA Health System. Our proceeds of approximately $43 million from this sale fully recovered our mortgage loan balance in addition to certain past due amounts.

Other Leasing Activity

On July 24, 2020, we re-leased our five San Antonio, Texas free standing emergency facilities (with a total investment of approximately $30 million) to Methodist Healthcare System of San Antonio, a joint venture between HCA Healthcare and Methodist Healthcare Ministries of South Texas, pursuant to a long-term master lease. As a result, we recorded an approximate $1.5 million write-off of straight-line rent in the 2020 third quarter.

Loans

The following is a summary of our loans (net of allowance for credit loss in 2020) ($ amounts in thousands):

	As of December 31, 2020					As of December 31, 2019
	Balance		Weighted-Average Interest Rate			Balance		Weighted-Average Interest Rate
Mortgage loans	$	248,080		8.5	%	$	1,275,022		9.0	%
Acquisition loans		338,273		7.6	%		123,893		7.7	%
Other loans		520,095		5.8	%		420,939		5.7	%
	$	1,106,448				$	1,819,854

Our mortgage loans at December 31, 2020 cover six of our properties with four operators. The decrease from the prior year primarily relates to the conversion of Steward mortgage loans for the underlying fee simple real estate of two general acute care hospitals as more fully described under “New Investments” in this same Note 3, along with the repayment of approximately $328 million mortgage loans from Prime.

The increase in acquisition loans primarily relates to the $205 million loan to the new international joint venture described under “New Investments” in this same Note 3.

Other loans consist of loans to our tenants for working capital and other purposes and include our shareholder loan made to the joint venture with Primotop on August 31, 2018 (as more fully described above in this Note 3) in the amount of €290 million.

Concentration of Credit Risks

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

Facility concentration – We had no investment in any single property greater than 4% of our total assets at December 31, 2020 or December 31, 2019.

Operator concentration – For the year ended December 31, 2020, revenue from Steward, Circle, and Prospect represented 30%, 13%, and 12%, respectively, of our total revenues. In comparison, Steward represented 42% of our total revenues for the year ended December 31, 2019, while Circle and Prospect represented less than 10%.

Geographic concentration – At December 31, 2020, investments in the U.S, Europe, Australia, and South America represented approximately 65%, 28%, 6%, and 1%, respectively, of our total assets. In comparison, investments in the U.S., Europe, and Australia represented approximately 74%, 20%, and 6%, respectively, of our total assets at December 31, 2019.

Facility type concentration – For the year ended December 31, 2020, approximately 87% of our revenues are from our general acute care facilities, while rehabilitation and long-term acute care facilities made up 8% and 3%, respectively. Freestanding ER/urgent care facilities and behavioral health facilities combined to make up the additional 2%. In comparison, general acute care, rehabilitation, and long-term acute care facilities made up 82%, 10%, and 3%, respectively, of our total revenues for the year ended December 31, 2019, while freestanding ER/urgent care facilities and behavioral health facilities combined to make up the additional 5%.

Related Party Transactions

Lease and interest revenue earned from tenants and real estate joint ventures in which we had an equity interest (accounted for under either the equity or fair value option methods) during the year were $29.8 million, $85.3 million, and $102.2 million for 2020, 2019, and 2018, respectively.

See subsections “New Investments” and “Disposals” in this Note 3 as it relates to our investments in the new international, Primotop, and Infracore ventures and the Ernest recapitalization for other related party transactions during 2020, 2019, and 2018.
