Organization, Consolidation and Presentation of Financial Statements [Abstract]
BUSINESS	BUSINESS Organization. MGM Growth Properties LLC (“MGP” or the “Company”) is a limited liability company that was organized in Delaware in October 2015. MGP conducts its operations through MGM Growth Properties Operating Partnership LP (the “Operating Partnership”), a Delaware limited partnership that was formed in January 2016 and acquired by MGP in April 2016. The Company elected to be treated as a real estate investment trust (“REIT”) commencing with its taxable year ended December 31, 2016. MGP is a publicly traded REIT primarily engaged through its investment in the Operating Partnership in the real property business, which consists of owning, acquiring and leasing large-scale destination entertainment and leisure properties, whose tenants generally offer casino gaming, hotel, convention, dining, entertainment and retail. A wholly owned subsidiary of the Operating Partnership (the “Landlord”) leases all of its real estate properties to a wholly owned subsidiary (the “Tenant”) of MGM Resorts International (“MGM”) under a master lease agreement (the “Master Lease”). As of June 30, 2019 , there were approximately 292.3 million Operating Partnership units outstanding in the Operating Partnership, of which MGM owned approximately 199.7 million, or 68.3% , and MGP owned the remaining 31.7% . MGM’s Operating Partnership units are exchangeable for Class A shares of MGP on a one -to-one basis, or cash at the fair value of a Class A share. MGP’s independent conflicts committee determines the settlement method for any such exchanges. MGM’s indirect ownership of these Operating Partnership units is recognized as a noncontrolling interest in MGP’s financial statements. A wholly owned subsidiary of MGP is the general partner of the Operating Partnership and operates and controls all of its business affairs. As a result, MGP consolidates the Operating Partnership and its subsidiaries. MGM also has ownership of MGP’s outstanding Class B share. The Class B share is a non-economic interest in MGP which does not provide its holder any rights to profits or losses or any rights to receive distributions from the operations of MGP or upon liquidation or winding up of MGP but which represents a majority of the voting power of MGP’s shares. As a result, MGP continues to be controlled by MGM through its majority voting rights and is consolidated by MGM. Empire City Transaction On January 29, 2019, the Company acquired the developed real property associated with Empire City Casino (“Empire City”) from MGM upon its acquisition of Empire City (“Empire City Transaction”) and Empire City was added to the existing Master Lease between the Landlord and Tenant. Refer to Note 3 for additional details on the Empire City Transaction and Note 5 for further discussion on the Master Lease. Park MGM Transaction On March 7, 2019, the Company completed the transaction relating to renovations undertaken by MGM Resorts regarding the Park MGM and NoMad Las Vegas property (the “Park MGM Transaction”). Refer to Note 5 for further discussion on the Master Lease. Northfield OpCo Transaction

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of presentation. The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information set forth in the Accounting Standards Codification (“ASC”), as published by the Financial Accounting Standards Board (“FASB”), and with the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. All adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of results for the interim period have been included. Certain reclassifications have been made to conform the prior period presentation. The accompanying condensed consolidated financial statements and related notes should be read in conjunction with the audited financial statements and notes thereto included in the Company’s most recent Annual Report on Form 10-K. Variable Interest Entities. The condensed consolidated financial statements of MGP include the accounts of the Operating Partnership, a variable interest entity (“VIE”) of which the Company is the primary beneficiary, as well as its wholly owned and majority-owned subsidiaries, which represents all of MGP’s assets and liabilities. As MGP holds what is deemed a majority voting interest in the Operating Partnership through its ownership of the Operating Partnership’s sole general partner, it qualifies for the exemption from providing certain of the required disclosures associated with investments in VIEs. The condensed consolidated financial statements of the Operating Partnership include the accounts of its wholly owned subsidiary, the Landlord, which owns the real estate, a VIE of which the Operating Partnership is the primary beneficiary. As of June 30, 2019 , on a consolidated basis the Landlord had total assets of $11.8 billion primarily related to its real estate assets, and total liabilities of $450.1 million primarily related to its deferred revenue and operating lease liabilities. Noncontrolling interest. The Company presents noncontrolling interest and classifies such interest as a component of consolidated shareholders’ equity, separate from the Company’s Class A shareholders’ equity. Noncontrolling interest in the Company represents Operating Partnership units currently held by subsidiaries of MGM. Net income or loss of the Operating Partnership is allocated to its noncontrolling interest based on the noncontrolling interest’s ownership percentage in the Operating Partnership except for income tax expenses. Ownership percentage is calculated by dividing the number of Operating Partnership units held by the noncontrolling interest by the total Operating Partnership units held by the noncontrolling interest and the Company. Issuance of additional Class A shares and Operating Partnership units changes the ownership interests of both the noncontrolling interest and the Company. Such transactions and the related proceeds are treated as capital transactions. MGM may tender its Operating Partnership units for redemption by the Operating Partnership in exchange for cash equal to the market price of MGP’s Class A shares at the time of redemption or for unregistered Class A shares on a one-for-one basis. Such selection to pay cash or issue Class A shares to satisfy an Operating Partnership unitholder’s redemption request is solely within the control of MGP’s independent conflicts committee. Fair value measurements. Fair value measurements are utilized in the accounting and impairment assessments of its long-lived assets, assets acquired and liabilities assumed in a business combination, and goodwill and other intangible assets. Fair value measurements also affect the Company’s accounting for certain of its financial assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured according to a hierarchy that includes: Level 1 inputs, such as quoted prices in an active market; Level 2 inputs, which are observable inputs for similar assets; or Level 3 inputs, which are unobservable inputs. The Company used the following inputs in its fair value measurements: • Level 2 inputs for its long-term debt fair value disclosures. See Note 6; and • Level 2 inputs when measuring the fair value of its interest rate swaps. See Note 7. Real estate investments. Real estate investments consist of land, buildings, improvements and integral equipment related to the Landlord. The majority of the Company’s real property was contributed or acquired by the Operating Partnership from MGM as transactions between entities under common control, and as a result, such real estate was initially recorded by the Company at MGM’s historical cost basis, less accumulated depreciation (i.e., there was no change in the basis of the contributed assets), as of the contribution or acquisition dates. For real property acquired from third parties, such assets were recognized at fair value at the acquisition date. Costs of maintenance and repairs to real estate investments are the responsibility of the Tenant under the Master Lease. Although the Tenant is responsible for all capital expenditures during the term of the Master Lease, if, in the future, a deconsolidation event occurs, the Company will be required to pay the Tenant, should the Tenant so elect, for certain capital improvements that would not constitute “normal tenant improvements” in accordance with U.S. GAAP (“Non-Normal Tenant Improvements”), subject to an initial cap of $100 million in the first year of the Master Lease increasing annually by $75 million each year thereafter. The Company will be entitled to receive additional rent based on the 10 -year Treasury yield plus 600 basis points multiplied by the value of the new capital improvements the Company is required to pay for in connection with a deconsolidation event and such capital improvements will be subject to the terms of the Master Lease. Examples of Non-Normal Tenant Improvements include the costs of structural elements at the properties, including capital improvements that expand the footprint or square footage of any of the properties or extend the useful life of the properties, as well as equipment that would be a necessary improvement at any of the properties, including initial installation of elevators, air conditioning systems or electrical wiring. Non-Normal Tenant Improvements were $48.4 million at June 30, 2019 . Lease incentive asset. The Company’s lease incentive asset consists of the consideration paid to MGM as part of the Park MGM Transaction, net of the deferred revenue balance associated with Non-Normal Tenant Improvements related to Park MGM, which was derecognized. The Company amortizes the lease incentive asset as a reduction of rental income over the remaining term of the Master Lease. Deferred revenue. The Company received nonmonetary consideration related to Non-Normal Tenant Improvements as they became MGP’s property pursuant to the Master Lease and recognized the cost basis of Non-Normal Tenant Improvements as real estate investments and deferred revenue. The Company depreciates the real estate investments over their estimated useful lives and amortizes the deferred revenue as additional rental revenue over the remaining term of the Master Lease once the related real estate assets were placed in service. Ground lease and other reimbursable expenses. Ground lease and other reimbursable expenses arise from costs which upon adoption of ASC 842, includes ground lease rent paid directly by the Tenant to the third-party lessor on behalf of the Company. Prior to the adoption of ASC 842 on January 1, 2019, as further described below, reimbursable expenses also included property taxes paid for by the Tenant on behalf of the Company pursuant to the triple-net lease terms of the Master Lease. Revenue recognition. Rental revenue under the Master Lease is recognized on a straight-line basis over the non-cancelable term and reasonably assured renewal periods, which includes the initial lease term of ten years and all four additional five -year terms under the Master Lease, for all contractual revenues that are determined to be fixed and measurable. The difference between such rental revenue earned and the cash paid under the provisions of the Master Lease is recorded as deferred rent receivable and included as a component of tenant and other receivables, net or as deferred revenue if cash rent due exceeds rental revenue earned. Tenant reimbursement revenue and other reflects the amortization of deferred revenue relating to Non-Normal Tenant Improvements as well as the non-cash ground lease reimbursement revenue from the Tenant. Prior to the adoption of ASC 842 in 2019, the Company also reflected within this amount the revenue that arises from costs for which the Company is the primary obligor that are required to be paid by the Tenant or reimbursed to the Company pursuant to the Master Lease such as property taxes. This revenue is recognized in the same periods as the expense is incurred. Lessee leases. The Company determines if an arrangement is or contains a lease at inception or modification of the arrangement. An arrangement is or contains a lease if there are identified assets and the right to control the use of an identified asset is conveyed for a period in exchange for consideration. Control over the use of the identified asset means the lessee has both the right to obtain substantially all of the economic benefits from the use of the asset and the right to direct the use of the asset. For leases with terms greater than twelve months, the operating lease right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The initial measurement of the operating lease ROU assets also includes any prepaid lease payments and are reduced by any previously accrued deferred rent. When available, the Company uses the rate implicit in the lease to discount lease payments to present value; however, most of the Company’s leases do not provide a readily determinable implicit rate. Therefore, the Company uses its incremental borrowing rate to discount the lease payments based on the information available at commencement date. Certain of the Company’s leases include fixed rental escalation clauses that are factored into the determination of lease payments. Lease terms include options to extend or terminate the lease when it is reasonably certain that such option will be exercised. Lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease term. Reportable segment. The Company’s TRS liquidated in connection with the Northfield OpCo Transaction in April 2019 and, accordingly, the Company now solely generates revenue from its real estate properties. The Company’s real estate properties are similar to one another in that they consist of large-scale destination entertainment and leisure resorts and related offerings, whose tenants generally offer casino gaming, hotel, convention, dining, entertainment and retail, are held by a subsidiary of the Operating Partnership, have similar economic characteristics and are governed under a single Master Lease. As such, the properties are reported as one reportable segment. Income tax provision. For interim income tax reporting the Company estimates its annual effective tax rate and applies it to its year-to-date ordinary income. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. The Company’s effective income tax rate on income from continuing operations was 5.6% and 3.1% for the three and six months ended June 30, 2019 , respectively. The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement and tax basis of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Landlord is required to join in the filing of a New Jersey consolidated corporation business tax return under the New Jersey Casino Control Act and include in such return its income and expenses associated with its New Jersey assets and is thus subject to an entity level tax in New Jersey. Although the consolidated New Jersey return also includes MGM and certain of its subsidiaries, the Company is required to record New Jersey state income taxes in the accompanying financial statements as if the Landlord was taxed for state purposes on a stand-alone basis. The Company and MGM have entered into a tax sharing agreement providing for an allocation of taxes due in the consolidated New Jersey return. Pursuant to this agreement, the Landlord will only be responsible for New Jersey taxes on any gain that may be realized upon a future sale of the New Jersey assets resulting solely from an appreciation in value of such assets over their value on the date they were contributed to the Landlord by a subsidiary of MGM. MGM is responsible for all other taxes reported in the New Jersey consolidated return and, accordingly, the related income tax balances related to such taxes is reflected within noncontrolling interest within the accompanying financial statements. No amounts were due to MGM under the tax sharing agreement as of June 30, 2019 and December 31, 2018 . Prior to April 1, 2019, the Company’s TRS owned the real estate assets and operations of Northfield and the Company recorded a tax provision on the income from the TRS operations. In connection with the Northfield OpCo Transaction, the TRS was liquidated on April 1, 2019. Concurrently, a subsidiary of MGM acquired the Northfield operations and the Company retained the real estate. Consequently, the Company does not provide a tax provision on TRS operations after April 1, 2019. Recently issued accounting standards. In February 2016, the FASB issued ASC 842 “Leases (Topic 842)”, which replaces the existing guidance in Topic 840, “Leases”, (“ASC 842”). ASC 842 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. ASC 842 requires a dual approach for lessee accounting under which a lessee would classify and account for its lease agreements as either finance or operating. Both finance and operating leases will result in the lessee recognizing a ROU asset and a corresponding lease liability. For finance leases, the lessee will recognize interest expense associated with the lease liability and depreciation expense associated with the ROU asset; and for operating leases, the lessee will recognize straight-line rent expense. The Company adopted ASC 842 on January 1, 2019 utilizing the simplified transition method and accordingly did not recast comparative period financial information. The Company elected the package of practical expedients available under ASC 842, which includes that the Company need not reassess the lease classification for existing contracts. Accordingly, the Master Lease continues to be classified as an operating lease as of January 1, 2019. ASC 842 requires lessors to exclude from variable payments, and therefore from revenue, lessor costs paid by lessees directly to third parties. Under the Master Lease, the lessee pays property tax directly to third parties; accordingly, the Company no longer reflect such costs as “Tenant reimbursements and other” within revenues or “Ground lease and other reimbursable expenses” within expenses as of January 1, 2019. The Company is also a lessee in lease arrangements, primarily for land underlying certain of its properties. As a result of adoption, the Company recognized approximately $279.9 million of operating ROU assets and approximately $333.5 million of operating lease liabilities as of January 1, 2019.

Acquisitions and dispositions	ACQUISITIONS AND DISPOSITIONS Empire City Acquisition As discussed in Note 1, on January 29, 2019, the Company acquired the developed real property associated with Empire City from MGM for fair value consideration of approximately $634.4 million . The Company funded the acquisition of the developed real property from MGM through the assumption of approximately $246.0 million of indebtedness, which was repaid with borrowings under its senior secured credit facility, and the issuance of approximately 12.9 million Operating Partnership units to MGM. Empire City was added to the existing Master Lease between the Landlord and Tenant, as further discussed in Note 5. The Empire City Transaction was accounted for as a transaction between entities under common control and, therefore, the Company recorded the Empire City real estate assets at the carryover value of $625.0 million from MGM with the difference between the purchase price and carrying value of assets recorded, which was approximately $9.4 million , recorded as a reduction to additional paid-in-capital. Northfield Acquisition and Northfield OpCo Transaction On July 6, 2018 the TRS completed its acquisition of 100% of the membership interests of Northfield for a purchase price of approximately $1.1 billion . The Company recognized 100% of the assets and liabilities of Northfield at fair value at the date of the acquisition. On April 1, 2019, the Company’s TRS liquidated. Concurrently, a subsidiary of MGM acquired Northfield OpCo for fair value consideration transferred of approximately $305.2 million consisting primarily of approximately 9.4 million Operating Partnership units that were ultimately redeemed by the Operating Partnership and the Company retained the real estate assets. Subsequently, MGM rebranded Northfield OpCo to MGM Northfield Park, which was then added to the existing Master Lease between the Landlord and Tenant. Refer to Note 5 for further discussion on the Master Lease. The Northfield OpCo Transaction was accounted for as a transaction between entities under common control and, therefore, the Company had carried the Northfield OpCo operating assets and liabilities as held and used until the close of the transaction on April 1, 2019. As a transaction between entities under common control, the Company recorded the difference between the purchase price of $305.2 million and the carrying value of net assets transferred of $292.3 million to additional paid-in-capital.

Leases [Abstract]
Leases	LEASES Master Lease. Pursuant to the Master Lease, the Tenant has leased the Company’s real estate properties. The Master Lease is accounted for as an operating lease and has an initial lease term of ten years that began on April 25, 2016 (other than with respect to MGM National Harbor, as described below) with the potential to extend the term for four additional five -year terms thereafter at the option of the Tenant. With respect to MGM National Harbor, the initial lease term ends on August 31, 2024. Thereafter, the initial term of the Master Lease with respect to MGM National Harbor may be renewed at the option of the Tenant for an initial renewal period lasting until the earlier of the end of the then-current term of the Master Lease or the next renewal term (depending on whether MGM elects to renew the other properties under the Master Lease in connection with the expiration of the initial ten-year term). If, however, the Tenant chooses not to renew the lease with respect to MGM National Harbor after the initial MGM National Harbor term under the Master Lease, the Tenant would also lose the right to renew the Master Lease with respect to the rest of the properties when the initial ten-year lease term ends related to the rest of the properties in 2026. On January 29, 2019, Empire City was added to the existing Master Lease between the Landlord and Tenant. As a result, the annual rent payment to MGP increased by $50 million , prorated for the remainder of the lease year. Consistent with the Master Lease terms, 90% of this rent is fixed and will contractually grow at 2% per year until 2022. In addition, pursuant to the Master Lease, MGP has a right of first offer with respect to certain undeveloped land adjacent to the property to the extent MGM develops additional gaming facilities and chooses to sell or transfer the property in the future. On March 7, 2019, the Company completed the Park MGM Transaction and amended the existing Master Lease between the Landlord and Tenant concurrent with which the Company paid $637.5 million , of which $605.6 million was cash and the remainder was the issuance of approximately 1.0 million of Operating Partnership units, to a subsidiary of MGM and, as a result, the annual rent payment to the Company increased by $50 million , prorated for the remainder of the lease year. Consistent with the Master Lease terms, 90% of this rent is fixed and will contractually grow at 2% per year until 2022. The Company recorded a lease incentive asset which represents the consideration paid, less the existing deferred revenue balance of $94.0 million relating to the non-normal tenant improvements recorded for Park MGM, which was derecognized. The Company was required to reassess the lease classification of the Master Lease and concluded that the Master Lease continued to be an operating lease. On April 1, 2019, MGM Northfield Park was added to the existing Master Lease and the annual rent payment increased by $60 million . Consistent with the Master Lease terms, 90% of this rent is fixed and will contractually grow at 2% per year until 2022. The annual rent payments under the Master Lease for the fourth lease year, which commenced on April 1, 2019, increased to $946.1 million from $770.3 million at the start of the third lease year. The increase was a result of the $50 million in additional rent for each of the Park MGM Transaction and Empire City in the beginning of 2019, the $60 million of additional rent for MGM Northfield Park on April 1, 2019, as well as the third 2.0% fixed annual rent escalator that went into effect on April 1, 2019. Straight-line rental revenues from the Master Lease, which includes the lease incentive asset amortization, were $219.8 million and $416.7 million for the three and six months ended June 30, 2019 , respectively, and were $186.6 million and $373.1 million for the three and six months ended June 30, 2018 , respectively.

Under the Master Lease, future non-cancelable minimum rental payments, which are the payments under the initial 10-year term and do not include the four five-year renewal options and, with respect to National Harbor, through August 31, 2024, are as follows as of June 30, 2019 : Year ending December 31, (in thousands) 2019 $ 473,030 2020 958,894 2021 976,262 2022 912,751 2023 890,126 Thereafter 1,922,713 $ 6,133,776 Lessee Leases.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies - (Policies)	6 Months Ended
	Jun. 30, 2019
Accounting Policies [Abstract]
Basis of Presentation	Basis of presentation. The accompanying condensed consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information set forth in the Accounting Standards Codification (“ASC”), as published by the Financial Accounting Standards Board (“FASB”), and with the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. All adjustments (consisting of normal recurring accruals) considered necessary for a fair statement of results for the interim period have been included. Certain reclassifications have been made to conform the prior period presentation.
Variable Interest Entities	Variable Interest Entities.
Noncontrolling Interest	Noncontrolling interest. The Company presents noncontrolling interest and classifies such interest as a component of consolidated shareholders’ equity, separate from the Company’s Class A shareholders’ equity. Noncontrolling interest in the Company represents Operating Partnership units currently held by subsidiaries of MGM. Net income or loss of the Operating Partnership is allocated to its noncontrolling interest based on the noncontrolling interest’s ownership percentage in the Operating Partnership except for income tax expenses. Ownership percentage is calculated by dividing the number of Operating Partnership units held by the noncontrolling interest by the total Operating Partnership units held by the noncontrolling interest and the Company. Issuance of additional Class A shares and Operating Partnership units changes the ownership interests of both the noncontrolling interest and the Company. Such transactions and the related proceeds are treated as capital transactions. MGM may tender its Operating Partnership units for redemption by the Operating Partnership in exchange for cash equal to the market price of MGP’s Class A shares at the time of redemption or for unregistered Class A shares on a one-for-one basis. Such selection to pay cash or issue Class A shares to satisfy an Operating Partnership unitholder’s redemption request is solely within the control of MGP’s independent conflicts committee.
Fair Value Measurements	Fair value measurements. Fair value measurements are utilized in the accounting and impairment assessments of its long-lived assets, assets acquired and liabilities assumed in a business combination, and goodwill and other intangible assets. Fair value measurements also affect the Company’s accounting for certain of its financial assets and liabilities. Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date and is measured according to a hierarchy that includes: Level 1 inputs, such as quoted prices in an active market; Level 2 inputs, which are observable inputs for similar assets; or Level 3 inputs, which are unobservable inputs. The Company used the following inputs in its fair value measurements: • Level 2 inputs for its long-term debt fair value disclosures. See Note 6; and • Level 2 inputs when measuring the fair value of its interest rate swaps. See Note 7.
Real Estate Investments	Real estate investments. Real estate investments consist of land, buildings, improvements and integral equipment related to the Landlord. The majority of the Company’s real property was contributed or acquired by the Operating Partnership from MGM as transactions between entities under common control, and as a result, such real estate was initially recorded by the Company at MGM’s historical cost basis, less accumulated depreciation (i.e., there was no change in the basis of the contributed assets), as of the contribution or acquisition dates. For real property acquired from third parties, such assets were recognized at fair value at the acquisition date. Costs of maintenance and repairs to real estate investments are the responsibility of the Tenant under the Master Lease.
Lease Incentive Asset	Lease incentive asset. The Company’s lease incentive asset consists of the consideration paid to MGM as part of the Park MGM Transaction, net of the deferred revenue balance associated with Non-Normal Tenant Improvements related to Park MGM, which was derecognized. The Company amortizes the lease incentive asset as a reduction of rental income over the remaining term of the Master Lease.
Revenue Recognition	Deferred revenue. The Company received nonmonetary consideration related to Non-Normal Tenant Improvements as they became MGP’s property pursuant to the Master Lease and recognized the cost basis of Non-Normal Tenant Improvements as real estate investments and deferred revenue. The Company depreciates the real estate investments over their estimated useful lives and amortizes the deferred revenue as additional rental revenue over the remaining term of the Master Lease once the related real estate assets were placed in service. Ground lease and other reimbursable expenses. Ground lease and other reimbursable expenses arise from costs which upon adoption of ASC 842, includes ground lease rent paid directly by the Tenant to the third-party lessor on behalf of the Company. Prior to the adoption of ASC 842 on January 1, 2019, as further described below, reimbursable expenses also included property taxes paid for by the Tenant on behalf of the Company pursuant to the triple-net lease terms of the Master Lease. Revenue recognition. Rental revenue under the Master Lease is recognized on a straight-line basis over the non-cancelable term and reasonably assured renewal periods, which includes the initial lease term of ten years and all four additional five -year terms under the Master Lease, for all contractual revenues that are determined to be fixed and measurable. The difference between such rental revenue earned and the cash paid under the provisions of the Master Lease is recorded as deferred rent receivable and included as a component of tenant and other receivables, net or as deferred revenue if cash rent due exceeds rental revenue earned. Tenant reimbursement revenue and other reflects the amortization of deferred revenue relating to Non-Normal Tenant Improvements as well as the non-cash ground lease reimbursement revenue from the Tenant. Prior to the adoption of ASC 842 in 2019, the Company also reflected within this amount the revenue that arises from costs for which the Company is the primary obligor that are required to be paid by the Tenant or reimbursed to the Company pursuant to the Master Lease such as property taxes. This revenue is recognized in the same periods as the expense is incurred.
Lessee Leases	Lessee leases. The Company determines if an arrangement is or contains a lease at inception or modification of the arrangement. An arrangement is or contains a lease if there are identified assets and the right to control the use of an identified asset is conveyed for a period in exchange for consideration. Control over the use of the identified asset means the lessee has both the right to obtain substantially all of the economic benefits from the use of the asset and the right to direct the use of the asset. For leases with terms greater than twelve months, the operating lease right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. The initial measurement of the operating lease ROU assets also includes any prepaid lease payments and are reduced by any previously accrued deferred rent. When available, the Company uses the rate implicit in the lease to discount lease payments to present value; however, most of the Company’s leases do not provide a readily determinable implicit rate. Therefore, the Company uses its incremental borrowing rate to discount the lease payments based on the information available at commencement date. Certain of the Company’s leases include fixed rental escalation clauses that are factored into the determination of lease payments. Lease terms include options to extend or terminate the lease when it is reasonably certain that such option will be exercised. Lease expense for minimum lease payments is recognized on a straight-line basis over the expected lease term.
Income Tax Provision	Income tax provision. For interim income tax reporting the Company estimates its annual effective tax rate and applies it to its year-to-date ordinary income. The tax effects of unusual or infrequently occurring items, including changes in judgment about valuation allowances and effects of changes in tax laws or rates, are reported in the interim period in which they occur. The Company’s effective income tax rate on income from continuing operations was 5.6% and 3.1% for the three and six months ended June 30, 2019 , respectively. The Company accounts for income taxes under the asset and liability method, which requires the recognition of deferred tax assets and liabilities for the expected future tax consequences of events that have been included in the financial statements. Under this method, the Company determines deferred tax assets and liabilities on the basis of the differences between the financial statement and tax basis of assets and liabilities by using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period that includes the enactment date. The Landlord is required to join in the filing of a New Jersey consolidated corporation business tax return under the New Jersey Casino Control Act and include in such return its income and expenses associated with its New Jersey assets and is thus subject to an entity level tax in New Jersey. Although the consolidated New Jersey return also includes MGM and certain of its subsidiaries, the Company is required to record New Jersey state income taxes in the accompanying financial statements as if the Landlord was taxed for state purposes on a stand-alone basis. The Company and MGM have entered into a tax sharing agreement providing for an allocation of taxes due in the consolidated New Jersey return. Pursuant to this agreement, the Landlord will only be responsible for New Jersey taxes on any gain that may be realized upon a future sale of the New Jersey assets resulting solely from an appreciation in value of such assets over their value on the date they were contributed to the Landlord by a subsidiary of MGM. MGM is responsible for all other taxes reported in the New Jersey consolidated return and, accordingly, the related income tax balances related to such taxes is reflected within noncontrolling interest within the accompanying financial statements. No amounts were due to MGM under the tax sharing agreement as of June 30, 2019 and December 31, 2018 .
Recently Issued Accounting Pronouncements	Recently issued accounting standards. In February 2016, the FASB issued ASC 842 “Leases (Topic 842)”, which replaces the existing guidance in Topic 840, “Leases”, (“ASC 842”). ASC 842 is effective for fiscal years, and interim periods within those years, beginning after December 15, 2018. ASC 842 requires a dual approach for lessee accounting under which a lessee would classify and account for its lease agreements as either finance or operating. Both finance and operating leases will result in the lessee recognizing a ROU asset and a corresponding lease liability. For finance leases, the lessee will recognize interest expense associated with the lease liability and depreciation expense associated with the ROU asset; and for operating leases, the lessee will recognize straight-line rent expense. The Company adopted ASC 842 on January 1, 2019 utilizing the simplified transition method and accordingly did not recast comparative period financial information. The Company elected the package of practical expedients available under ASC 842, which includes that the Company need not reassess the lease classification for existing contracts. Accordingly, the Master Lease continues to be classified as an operating lease as of January 1, 2019. ASC 842 requires lessors to exclude from variable payments, and therefore from revenue, lessor costs paid by lessees directly to third parties. Under the Master Lease, the lessee pays property tax directly to third parties; accordingly, the Company no longer reflect such costs as “Tenant reimbursements and other” within revenues or “Ground lease and other reimbursable expenses” within expenses as of January 1, 2019. The Company is also a lessee in lease arrangements, primarily for land underlying certain of its properties. As a result of adoption, the Company recognized approximately $279.9 million of operating ROU assets and approximately $333.5 million of operating lease liabilities as of January 1, 2019.
