| Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements of the Company included herein were prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and with the instructions to this Quarterly Report on Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements. The information furnished includes all adjustments and accruals of a normal recurring nature, which, in the opinion of management, are necessary for a fair statement of results for the interim periods. All intercompany accounts and transactions have been eliminated in consolidation. The results of operations for the three months ended March 31, 2019 are not necessarily indicative of the results for the entire year or any subsequent interim period. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto as of and for the year ended December 31, 2018 , which are included in the Company's Annual Report on Form 10-K filed with the U.S. Securities and Exchange Commission (the "SEC") on February 28, 2018. Except for those required by new accounting pronouncements discussed below, there have been no significant changes to the Company's significant accounting policies during the three months ended March 31, 2019 , other than those relating to new accounting pronouncements (see "Recently Issued Accounting Pronouncements" section below). The accompanying unaudited consolidated financial statements include the accounts of the Company, the OP and its subsidiaries. All intercompany accounts and transactions are eliminated in consolidation. In determining whether the Company has a controlling financial interest in a joint venture and the requirement to consolidate the accounts of that entity, management considers factors such as ownership interest, authority to make decisions and contractual and substantive participating rights of the other partners or members as well as whether the entity is a variable interest entity ("VIE") for which the Company is the primary beneficiary. The Company has determined that the OP is a VIE of which the Company is the primary beneficiary. Substantially all of the Company's assets and liabilities are held by the OP. Reclassifications The Company has aggregated revenue from its lease components and non-lease components (tenant operating expense reimbursements) into one line (see additional information in the “Recently Issued Accounting Pronouncements” section below. The prior period has been reclassified to conform to this presentation. Judgments and Estimates The Company regularly makes a number of estimates and assumptions relating to the reporting of assets and liabilities, the disclosure of contingent assets and liabilities, and the reported amounts of revenues and expenses in order to prepare its consolidated financial statements in conformity with GAAP. These estimates and assumptions are based on management's best estimates and judgment. Management evaluates its estimates and assumptions on an ongoing basis using historical experience and other factors, such as the prevailing economic and business environment. Management adjusts such estimates when facts and circumstances dictate. The most significant estimates management makes include recoverability of accounts receivable, allocation of property purchase price to tangible and intangible assets acquired and liabilities assumed, determination of impairment of long-lived assets, valuation of derivative financial instruments, valuation of compensation plans, and estimating the useful life of a long-lived asset. Actual results could differ materially from those estimated. Investments in Real Estate Investments in real estate are recorded at cost. Improvements and replacements are capitalized when they extend the useful life of the asset. Costs of repairs and maintenance are expensed as incurred. At the time an asset is acquired, the Company evaluates the inputs, processes and outputs of the asset acquired to determine if the transaction is a business combination or an asset acquisition. If an acquisition qualifies as a business combination, the related transaction costs are recorded as an expense in the consolidated statements of operations. If an acquisition qualifies as an asset acquisition, the related transaction costs are generally capitalized and subsequently amortized over the useful life of the acquired assets. In both a business combination and an asset acquisition, the Company allocates the purchase price of acquired properties to tangible and identifiable intangible assets or liabilities based on their respective fair values. Tangible assets may include land, land improvements, buildings, fixtures and tenant improvements on an as if vacant basis. Intangible assets or liabilities may include the value of in-place leases, above- and below- market leases and other identifiable assets or liabilities based on lease or property specific characteristics. In addition, any assumed mortgages receivable or payable and any assumed or issued non-controlling interests (in a business combination) are recorded at their estimated fair values. In allocating the fair value to assumed mortgages, amounts are recorded to debt premiums or discounts based on the present value of the estimated cash flows, which is calculated to account for either above or below-market interest rates. In a business combination, the difference between the purchase price and the fair value of identifiable net assets acquired is either recorded as goodwill or as a bargain purchase gain. In an asset acquisition, the difference between the acquisition price (including capitalized transaction costs) and the fair value of identifiable net assets acquired is allocated to the non-current assets. All acquisitions during the three months ended March 31, 2019 and the year ended December 31, 2018 were asset acquisitions. Purchase Accounting and Acquisition of Real Estate The Company allocates the purchase price of acquired properties to tangible and identifiable intangible assets acquired based on their respective fair values. Tangible assets include land, land improvements, buildings, fixtures and tenant improvements on an as-if vacant basis. The Company utilizes various estimates, processes and information to determine the as-if vacant property value. Estimates of value are made using customary methods, including data from appraisals, comparable sales, discounted cash flow analysis and other methods. Amounts allocated to land, land improvements, buildings and fixtures are based on cost segregation studies performed by independent third parties or on the Company's analysis of comparable properties in the Company's portfolio. Identifiable intangible assets include amounts allocated to acquire leases for above- and below-market lease rates, the value of in-place leases, and the value of customer relationships, as applicable. Factors considered in the analysis of the in-place lease intangibles include an estimate of carrying costs during the expected lease-up period for each property, taking into account current market conditions and costs to execute similar leases. In estimating carrying costs, the Company includes real estate taxes, insurance and other operating expenses and estimates of lost rentals at contract rates during the expected lease-up period, which typically ranges from 12 to 18 months . The Company also estimates costs to execute similar leases including leasing commissions, legal and other related expenses. Above-market and below-market lease values for acquired properties are initially recorded based on the present value (using a discount rate which reflects the risks associated with the leases acquired) of the difference between (i) the contractual amounts to be paid pursuant to each in-place lease, and (ii) management’s estimate of fair market lease rates for each corresponding in-place lease, measured over a period equal to the remaining term of the lease for above-market leases and the remaining initial term plus the term of any below-market fixed rate renewal options for below-market leases. The capitalized above-market lease values are amortized as a reduction of base rental revenue over the remaining terms of the respective leases, and the capitalized below-market lease values are amortized as an increase to base rental revenue over the remaining initial terms plus the terms of any below-market fixed rate renewal options of the respective leases. If a tenant with a below market rent renewal does not renew, any remaining unamortized amount will be taken into income at that time. The aggregate value of intangible assets related to customer relationship, as applicable, is measured based on the Company's evaluation of the specific characteristics of each tenant’s lease and the Company's overall relationship with the tenant. Characteristics considered by the Company in determining these values include the nature and extent of its 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, among other factors. In making estimates of fair values for purposes of allocating purchase price, the Company utilizes a number of sources, including independent appraisals that may be obtained in connection with the acquisition or financing of the respective property and other market data. The Company also considers information obtained about each property as a result of the Company's pre-acquisition due diligence in estimating the fair value of the tangible and intangible assets acquired and intangible liabilities assumed. Derivative Instruments The Company may use derivative financial instruments, including interest rate swaps, caps, options, floors and other interest rate derivative contracts, to hedge all or a portion of the interest rate risk associated with its borrowings. Certain of the Company's foreign operations expose the Company to fluctuations of foreign interest rates and exchange rates. These fluctuations may impact the value of the Company's cash receipts and payments in the Company's functional currency, the U.S. dollar ("USD"). The Company enters into derivative financial instruments to protect the value or fix the amount of certain obligations in terms of its functional currency. The Company records all derivatives on the consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether the Company has elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Derivatives may also be designated as hedges of the foreign currency exposure of a net investment in a foreign operation. Hedge accounting generally provides for the matching of the timing of gain or loss recognition on the hedging instrument with the recognition of the changes in the fair value of the hedged asset or liability that are attributable to the hedged risk in a fair value hedge or the earnings effect of the hedged forecasted transactions in a cash flow hedge. The Company may enter into derivative contracts that are intended to economically hedge certain risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. The accounting for subsequent changes in the fair value of these derivatives depends on whether each has been designed and qualifies for hedge accounting treatment. If the Company elects not to apply hedge accounting treatment (or for derivatives that do not qualify as hedges), any changes in the fair value of these derivative instruments is recognized immediately in gains (losses) on derivative instruments in the consolidated statements of operations. If a derivative is designated and qualifies for cash flow hedge accounting treatment, the change in the estimated fair value of the derivative is recorded in other comprehensive income (loss) in the consolidated statements of comprehensive income (loss) to the extent that it is effective. Any ineffective portion of a change in derivative fair value is immediately recorded in earnings. Impairment of Long Lived Assets When circumstances indicate the carrying value of a property may not be recoverable, the Company reviews the asset for impairment. This review is based on an estimate of the future undiscounted cash flows expected to result from the property’s use and eventual disposition. These estimates consider factors such as expected future operating income, market and other applicable trends and residual value, as well as the effects of leasing demand, competition and other factors. If impairment exists due to the inability to recover the carrying value of a property, an impairment loss is recorded to the extent that the carrying value exceeds the estimated fair value of the property for properties to be held and used. For properties held for sale, the impairment loss is the adjustment to fair value less estimated cost to dispose of the asset. These assessments have a direct impact on net income because recording an impairment loss results in an immediate negative adjustment to net earnings. Goodwill The Company evaluates goodwill for impairment at least annually, in the fourth quarter of each year, or upon the occurrence of a triggering event. A triggering event is an event or circumstance that would more likely than not reduce the fair value of a reporting unit below its carrying amount. The Company performed a qualitative assessment to determine whether it is more likely than not that the fair value of the reporting unit is less than its carrying value. Based on our assessment, we determined that the goodwill was not impaired as of December 31, 2018. Revenue Recognition The Company's revenues, which are derived primarily from lease contracts, which include rents that each tenant pays in accordance with the terms of each lease agreement and are reported on a straight-line basis over the initial term of the lease. As of March 31, 2019 , these leases had an average remaining lease term of 8.1 years. Since many of the Company's leases provide for rental increases at specified intervals, straight-line basis accounting requires the Company to record a receivable for, and include in revenues, unbilled rent receivables that the Company will only receive if the tenant makes all rent payments required through the expiration of the initial term of the lease. For new leases after acquisition, the commencement date is considered to be the date the lease modification is executed. The Company defers the revenue related to lease payments received from tenants in advance of their due dates. When the Company acquires a property, the acquisition date is considered to be the commencement date for purposes of this calculation. The Company's lease agreements generally require tenants to pay or reimburse the Company for all property operating expenses, in addition to base rent, however some limited property operating expenses that are not the responsibility of the tenant are absorbed by the Company. Operating expense reimbursements primarily reflect insurance costs and real estate taxes incurred by the Company and subsequently reimbursed by the tenant. Under ASC 842, the Company has elected to report combined lease and non-lease components in a single line “Revenue from tenants.” For comparative purposes, the Company has also elected to reflect prior revenue and reimbursements previously reported under ASC 840 on a single line as well. For expenses paid directly by the tenant, under both ASC 842 and 840, the Company has reflected them on a net basis. The following tables present future base rent payments on a cash basis due to the Company over the periods indicated. These amounts exclude tenant reimbursements and contingent rent payments, as applicable, that may be collected from certain tenants based on provisions related to sales thresholds and increases in annual rent based on exceeding certain economic indexes among other items. As of March 31, 2019 : (In thousands) Future Base Rent Payments (1) 2019 (remainder) $ 207,860 2020 280,334 2021 281,327 2022 272,251 2023 248,870 2024 204,921 Thereafter 663,302 $ 2,158,865 ___________________________________________ (1) Assumes exchange rates of £1.00 to $1.30 for GBP and €1.00 to $1.12 for EUR as of March 31, 2019 for illustrative purposes, as applicable. As of December 31, 2018: (In thousands) Future Base Rent Payments (1) 2019 $ 275,118 2020 278,651 2021 279,630 2022 270,569 2023 247,237 Thereafter 856,838 Total $ 2,208,043 ___________________________________________ (1) Assumes exchange rates of £1.00 to $1.27 for GBP and €1.00 to $1.14 for EUR as of December 31, 2018 for illustrative purposes, as applicable. The Company continually reviews receivables related to rent and unbilled rent receivables and determines collectability by taking into consideration the tenant’s payment history, the financial condition of the tenant, business conditions in the industry in which the tenant operates and economic conditions in the area in which the property is located. Under the new leasing standard (see the “Recently Issued Accounting Pronouncements” section below), the Company is required to assess, based on credit risk only, if it is probable that it will collect virtually all of the lease payments at lease commencement date and it must continue to reassess collectability periodically thereafter based on new facts and circumstances affecting the credit risk of the tenant. Partial reserves, or the ability to assume partial recovery are no longer permitted. If the Company determines that it is probable it will collect virtually all of the lease payments (rent and common area maintenance), the lease will continue to be accounted for on an accrual basis (i.e. straight-line). However, if the Company determines it is not probable that it will collect virtually all of the lease payments, the lease will be accounted for on a cash basis and a full reserve would be recorded on previously accrued amounts in cases where it was subsequently concluded that collection was not probable. Cost recoveries from tenants are included in Revenue from tenants on the accompanying consolidated statements of operations in the period the related costs are incurred, as applicable. Under ASC 842, uncollectable amounts are reflected as reductions in revenue. Under ASC 840, the Company recorded such amounts as bad debt expense as part of property operating expenses. During the three month periods ended March 31, 2019 and 2018, such amounts were $0.1 million . Income Taxes The Company elected to be taxed as a REIT under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the "Code"), beginning with the taxable year ended December 31, 2013. Commencing with such taxable year, the Company was organized to operate in such a manner as to qualify for taxation as a REIT under the Code and believes it has so qualified. The Company intends to continue to operate in such a manner to continue to qualify for taxation as a REIT, but no assurance can be given that it will operate in a manner so as to remain qualified as a REIT. As a REIT, the Company generally will not be subject to federal corporate income tax to the extent it distributes annually all of its REIT taxable income. REITs are subject to a number of other organizational and operational requirements. The Company conducts business in various states and municipalities within the U.S. and Puerto Rico, the United Kingdom and Western Europe and, as a result, the Company or one of its subsidiaries file income tax returns in the U.S. federal jurisdiction and various states and certain foreign jurisdictions. As a result, the Company may be subject to certain federal, state, local and foreign taxes on its income and assets, including alternative minimum taxes, taxes on any undistributed income and state, local or foreign income, franchise, property and transfer taxes. Any of these taxes decrease the Company's earnings and available cash. In addition, the Company's international assets and operations, including those owned through direct or indirect subsidiaries that are disregarded entities for U.S. federal income tax purposes, continue to be subject to taxation in the foreign jurisdictions where those assets are held or those operations are conducted. Significant judgment is required in determining the Company's tax provision and in evaluating its tax positions. The Company establishes tax reserves based on a benefit recognition model, which the Company believes could result in a greater amount of benefit (and a lower amount of reserve) being initially recognized in certain circumstances. Provided that the tax position is deemed more likely than not of being sustained, the Company recognizes the largest amount of tax benefit that is greater than 50 percent likely of being ultimately realized upon settlement. The Company derecognizes the tax position when the likelihood of the tax position being sustained is no longer more likely than not. The Company recognizes deferred income taxes in certain of its subsidiaries taxable in the U.S. or in foreign jurisdictions. Deferred income taxes are generally the result of temporary differences (items that are treated differently for tax purposes than for GAAP purposes). In addition, deferred tax assets arise from unutilized tax net operating losses, generated in prior years. The Company provides a valuation allowance against its deferred income tax assets when it believes that it is more likely than not that all or some portion of the deferred income tax asset may not be realized. Whenever a change in circumstances causes a change in the estimated realizability of the related deferred income tax asset, the resulting increase or decrease in the valuation allowance is included in deferred income tax expense (benefit). The Company derives most of its REIT taxable income from its real estate operations in the U.S. and has historically distributed all of its REIT taxable income to its shareholders. As such, the Company's real estate operations are generally not subject to federal tax, and accordingly, no provision has been made for U.S. federal income taxes in the consolidated financial statements for these operations. These operations may be subject to certain state, local, and foreign taxes, as applicable. The Company's deferred tax assets and liabilities are primarily the result of temporary differences related to the following: • Basis differences between tax and GAAP for certain international real estate investments. For income tax purposes, in certain acquisitions, the Company assumes the seller’s basis, or the carry-over basis, in the acquired assets. The carry-over basis is typically lower than the purchase price, or the GAAP basis, resulting in a deferred tax liability with an offsetting increase to goodwill or the acquired tangible or intangible assets; • Timing differences generated by differences in the GAAP basis and the tax basis of assets such as those related to capitalized acquisition costs and depreciation expense; and • Tax net operating losses in certain subsidiaries, including those domiciled in foreign jurisdictions that may be realized in future periods if the respective subsidiary generates sufficient taxable income. The Company recognizes current income tax expense for state and local income taxes and taxes incurred in its foreign jurisdictions. The Company's current income tax expense fluctuates from period to period based primarily on the timing of its taxable income. Reportable Segments The Company determined that it has one reportable segment, with activities related to investing in real estate. The Company’s investments in real estate generate rental revenue and other income through the leasing of properties, which comprise 100% of total consolidated revenues. Management evaluates the operating performance of the Company’s investments in real estate on an individual property level. Equity-Based Compensation The Company has a stock-based incentive award plan for its directors, and awards thereunder which are accounted for under the guidance for employee share based payments. The cost of services received in exchange for a stock award is measured at the grant date fair value of the award and the expense for such awards is included in equity-based compensation on consolidated statements of operations and is recognized over the vesting period or when the requirements for exercise of the award have been met (see Note 12 — Equity-Based Compensation ). Multi-Year Outperformance Agreements Concurrent with the Listing and modifications to the Fourth Amended and Restated Advisory Agreement (the "Advisory Agreement") by and among the Company, the OP and the Advisor, the Company entered into a multi-year outperformance agreement with the Advisor in June 2015 (the "2015 OPP"). Following the end of the performance period under the 2015 OPP on June 2, 2018, the Company entered into a new multi-year outperformance agreement with the Advisor in July 2018 (the "2018 OPP") (see Note 12 — Equity-Based Compensation). Under the 2015 OPP, the Company recorded equity-based compensation expense associated with the awards over the requisite service period on a graded basis. Under the 2018 OPP, effective June 2, 2018, we record equity-based compensation evenly over the requisite service period of approximately 2.8 years from the grant date. The equity-based compensation expense was adjusted each reporting period for changes in the estimated market-related performance. Under new accounting guidance adopted by the Company on January 1, 2019 total equity-based compensation expense calculated as of adoption of the new guidance will be fixed as of that date and will not be remeasured in subsequent periods. For additional information see Recently Issued Accounting Pronouncements section below. Recently Issued Accounting Pronouncements Adopted as of January 1, 2019: ASU No. 2016-02 — Leases In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) (“ASU 2016-02") which provides new guidance related to the accounting for leases, as well as the related disclosures. For lessors of real estate, leases are accounted for using an approach substantially the same as previous accounting guidance for operating leases and direct financing leases. For lessees, the new standard requires the application of a dual lease classification approach, classifying leases as either operating or finance leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. Lease expense for operating leases is recognized on a straight-line basis over the term of the lease, while lease expense for finance leases is recognized based on an effective interest method over the term of the lease. Also, lessees must recognize a right-of-use asset (“ROU”) and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Further, certain transactions where at inception of the lease the buyer-lessor accounted for the transaction as a purchase of real estate and a new lease, may now be required to have symmetrical accounting to the seller-lessee if the transaction was not a qualified sale-leaseback and accounted for as a financing transaction. Upon adoption, lessors were allowed a practical expedient, which the Company has elected, by class of underlying assets to account for lease and non-lease components (such as tenant reimbursements of property operating expenses) as a single lease component as an operating lease because (a) the non-lease components have the same timing and pattern of transfer as the associated lease component; and (b) the lease component, if accounted for separately, would be classified as an operating lease. Additionally, only incremental direct leasing costs may be capitalized under this new guidance, which is consistent with the Company’s existing policies. Also, upon adoption, companies were allowed a practical expedient package, which the Company has elected, that allowed the Company: (a) to not reassess whether any expired or existing contracts entered into prior to January 1, 2019 are or contain leases; (b) to not reassess the lease classification for any expired or existing leases entered into prior to January 1, 2019 (including assessing sale-leaseback transactions); and (c) to not reassess initial direct costs for any expired or existing leases entered into prior to January 1, 2019. As a result, all of the Company’s existing leases will continue to be classified as operating leases under the new standard. Further, any existing leases for which the property is leased to a tenant in a transaction that at inception was a sale-leaseback transaction will continue to be treated (absent a modification) as operating leases. The Company did not have any leases that would be considered financing leases as of January 1, 2019. The Company assessed the impact of adoption from both a lessor and lessee perspective, which is discussed in more detail below, and adopted the new guidance prospectively on January 1, 2019, using a prospective transition approach under which the Company elected to apply the guidance effective January 1, 2019 and not adjust prior comparative reporting periods (except for the Company’s presentation of lease revenue discussed below). Lessor Accounting As discussed above, the Company was not required to re-assess the classification of its leases, which are considered operating leases under ASU 2016-02. The following is a summary of the most significant impacts to the Company of the new accounting guidance, as lessor: • Because the Company elected the practical expedient noted above to not separate non-lease component revenue from the associated lease component, the Company has aggregated revenue from its lease components and non-lease components (tenant operating expense reimbursements) into one line. The prior period has been conformed to this new presentation. • Changes in the Company’s assessment of receivables that result in bad debt expense is now required to be recorded as an adjustment to revenue, rather than a charge to bad debt expense. This new classification applies for the first quarter of 2019 and reclassification of prior period amounts is not permitted. At transition on January 1, 2019, after assessing its reserve balances at December 31, 2018 under the new guidance, the Company wrote off accounts receivable of $3.4 million , net of $2.2 million in bad debt reserves as an adjustment to the opening balance of accumulated deficit, and accordingly rent for these tenants is currently recorded on a cash basis. • Indirect leasing costs in connection with new or extended tenant leases, if any, are being expensed. Under prior accounting guidance, the recognition would have been deferred. Lessee Accounting The Company is a lessee under ground leases for seven properties as of January 1, 2019. The following is a summary of the most significant impacts to the Company of the new accounting guidance, as lessee: • Upon adoption of the new standard, the Company recorded ROU assets and lease liabilities equal to $24.0 million for the present value of the lease payments related to its ground leases. These amounts are included in prepaid expenses and other assets and accounts payable and accrued expenses on the consolidated balance sheet. • The Company also reclassified $27.0 million , net related to amounts previously reported as above and below market ground lease intangibles to the ROU assets. For additional information and disclosures related to these operating leases, see Note 9 — Commitments and Contingencies.
