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 and six months ended June 30, 2018 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, 2017 , 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. There have been no significant changes to the Company's significant accounting policies during the six months ended June 30, 2018 , 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. Critical Accounting Policies 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. The Company adjusts such estimates when facts and circumstances dictate. The most significant estimates the Company 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. The Company evaluates the inputs, processes and outputs of each 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. 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 six months ended June 30, 2018 and the year ended December 31, 2017 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, including those acquired in the Company's merger (the "Merger"), which closed in December 2016, with American Realty Capital Global Trust II, Inc. ("Global II"), which was sponsored and advised by affiliates of AR Global, 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, excluding interest charges, 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 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 is not impaired as of June 30, 2018. Revenue Recognition The Company's revenues, which are derived primarily from rental income, 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. 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, 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 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 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. In the event that the collectability of a receivable is in doubt, the Company records an increase in the Company's allowance for uncollectible accounts or records a direct write-off of the receivable in the Company's consolidated statements of operations. Cost recoveries from tenants are included in operating expense reimbursement in the period the related costs are incurred, as applicable. 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 has been organized and operated in such a manner as to qualify for taxation as a REIT under the Code. 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. 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 Company's earnings and available cash. 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. Out-of-Period Adjustments During the three and six months ended June 30, 2017, the Company recorded $0.5 million of additional rental income and unbilled straight-line rent due to an error in the calculation of straight-line rent for one of the Company's properties acquired during 2014. The Company concluded that this adjustment was not material to the financial position or results of operations for the current period or any prior period. Also, during the year ended December 31, 2017, the Company identified certain historical errors in its current taxes payable as well as its statement of comprehensive income (loss), consolidated statement of changes in equity, and statement of cash flows since 2013 which impacted the quarterly financial statements and annual periods previously issued. Specifically, when recording its annual provision, the Company had adjusted its current taxes payable to the cumulative amount of taxes payable without consideration for cumulative payments. This adjustment was made with an offsetting amount in cumulative translation adjustments within other comprehensive income ("OCI") and accumulated other comprehensive income ("AOCI"). As of December 31, 2016, income taxes payable were overstated and AOCI was understated by $4.7 million . OCI was understated by $2.9 million , $1.9 million and overstated by $0.1 million for the years end December 31, 2016, 2015 and Pre-2015, respectively. We concluded that the errors noted above were not material to the current period or any historical periods presented and have adjusted the amounts on a cumulative basis in the year ended December 31, 2017. Recently Issued Accounting Pronouncements Adopted as of January 1, 2018: In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606 ), and has since issued several additional amendments thereto (collectively referred to herein as "ASC 606"). ASC 606 establishes a comprehensive model for entities to use in accounting for revenue arising from contracts with customers. Under ASC 606, an entity is required to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. ASC 606 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2017. A reporting entity may apply the amendments in ASC 606 using either a modified retrospective approach, by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption or a full retrospective approach. The Company adopted this guidance effective January 1, 2018, for all future financial statements issued, under the modified retrospective approach and it did not have an impact on the Company's consolidated financial statements. In January 2016, the FASB issued ASU 2016-01, Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities. Also, in February 2018, the FASB issued ASU 2018-03, Technical Corrections and Improvements to Financial Instruments-Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities , which updated guidance previously issued by ASU 2016-01. The guidance in ASU 2016-01 and 2018-01 amends the recognition and measurement of financial instruments. The new guidance significantly revises an entity’s accounting related to equity investments and the presentation of certain fair value changes for financial liabilities measured at fair value. Among other things, it also amends the presentation and disclosure requirements associated with the fair value of financial instruments. The Company adopted ASU 2016-01 and ASU 2018-03 effective January 1, 2018, using the modified retrospective transition method, and there was no material impact to the Company's consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which provides guidance on how certain transactions should be classified and presented in the statement of cash flows as either operating, investing or financing activities. Among other things, the update provides specific guidance on where to classify debt prepayment and extinguishment costs, payments for contingent consideration made after a business combination and distributions received from equity method investments. The Company adopted the new guidance beginning in the first quarter of 2018, with reclassification of prior period amounts, where applicable, and it did not have a significant impact on its statement of cash flows. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which revises the definition of a business. Amongst other things, this new guidance is applicable when evaluating whether an acquisition (disposal) should be treated as either a business acquisition (disposal) or an asset acquisition (disposal). Under the revised guidance, when substantially all of the fair value of gross assets acquired is concentrated in a single asset or group of similar assets, the assets acquired would not be considered a business. The revised guidance is effective for reporting periods beginning after December 15, 2017, and the amendments will be applied prospectively. The Company early adopted the provisions of this guidance effective January 1, 2017. While the Company's acquisitions have historically been classified as either business combinations or asset acquisitions, certain acquisitions that were classified as business combinations by the Company likely would have been considered asset acquisitions under the new standard. As a result, future transaction costs are more likely to be capitalized since the Company expects most of its future acquisitions to be classified as asset acquisitions under this new standard. All of the Company's acquisitions during 2018 and 2017 have been classified as asset acquisitions. In February 2017, the FASB issued ASU 2017-05, Other Income - Gains and Losses from the Derecognition of Nonfinancial Assets (Subtopic 610-20): Clarifying the Scope of Assets Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets, which provides guidance related to partial sales of non-financial assets, eliminates rules specifically addressing the sales of real estate, clarifies the definition of in substance non-financial assets, removes exception to the financial asset derecognition model and clarifies the accounting for contributions of non-financial assets to joint ventures. The Company adopted this guidance effective January 1, 2018 using the modified transition method. The Company expects that any future sales of real estate in which the Company retains a non-controlling interest in the property would result in the full gain amount being recognized at the time of the partial sale. Historically, the Company has not retained any interest in properties it has sold. In May 2017, the FASB issued ASU 2017-09, Compensation—Stock Compensation (Topic 718): Scope of Modification Accounting, which provides guidance that clarifies which changes to the terms or conditions of a share-based payment award require an entity to apply modification accounting. The update states that modification accounting should be used unless the fair value of the award, the vesting terms of the award, and the classification of the award as either equity or liability, all do not change as a result of the modification. The Company adopted this guidance effective January 1, 2018 using the modified retrospective transition method. The Company expects that any future modifications to the Company's issued share-based awards will be accounted for using modification accounting, unless the modification meets all of the exception criteria noted above. As a result, the modification would be treated as an exchange of the original award for a new award, with any incremental fair value being treated as additional compensation cost. Pending Adoption as of June 30, 2018: In February 2018, the FASB issued ASU 2018-02, Income Statement- Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income. The new guidance addresses the impact of Tax Cuts and Jobs Act signed into law on December 22, 2017, (“Tax Cuts and Jobs Act”) on items within accumulated other comprehensive income which do not reflect the appropriate tax rate. ASU 2018-02 allows the Company to retrospectively reclassify the income tax effects on items in Accumulated Other Comprehensive Income (“AOCI”) to retained earnings for all periods in which the effect of the change in the U.S. federal corporate income tax rate was recognized. In addition, all companies are required to disclose whether the company has elected to reclassify the income tax effects of the Tax Cuts and Jobs Act to retained earnings and disclose information about any other income tax effects that are reclassified from AOCI by the Company. The amendments are effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. Companies are required to apply the proposed amendments either in the period of adoption or retrospectively to each period (or periods) in which the effect of the change in the U.S. federal corporate income tax rate in the Tax Cuts and Jobs Act is recognized. The Company is currently evaluating the impact of this new guidance. ASU 2016-02, Leases (Topic 842) ("ASC 842") originally stated that companies would be required to bifurcate certain lease revenues between lease and non-lease components, however, the FASB issued ASU No. 2018-11, Leases (Topic 842): Targeted Improvements , in July 2018 ("ASU 2018-11"), which allows lessors a practical expedient by class of underlying assets to account for lease and non-lease components as a single lease component if certain criteria are met. Additionally, only incremental direct leasing costs may be capitalized under this new guidance, which is consistent with the Company’s existing policies. ASC 842 originally required a modified retrospective method of adoption, however, ASU 2018-11 indicates that companies may be permitted to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. The pronouncement allows some optional practical expedients. The Company does not expect this guidance to impact its existing lessor revenue recognition pattern. The Company expects to adopt this new guidance on January 1, 2019 and will continue to evaluate the impact of this guidance until it becomes effective. The Company is a lessee for some properties in which it has ground leases as of December 31, 2017. For these leases, the Company will be required to record a right-of-use asset and lease liability equal to the present value of the remaining lease payments upon adoption of this update. The new standard requires lessees to apply a dual lease classification approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase by the lessee. This classification will determine whether lease expense is recognized based on an effective interest method or on a straight line basis over the term of the lease, respectively. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a |
