Summary of Significant Accounting Policies | Summary of Significant Accounting Policies Basis of Quarterly Presentation The accompanying unaudited consolidated financial statements and related notes of the Company have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial reporting and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, certain information and note disclosures normally included in the consolidated financial statements prepared under U.S. GAAP have been condensed or omitted. In the opinion of management, all adjustments considered necessary for a fair statement of the Company’s financial position, results of operations and cash flows have been included and are of a normal and recurring nature. The operating results presented for interim periods are not necessarily indicative of the results that may be expected for any other interim period or for the entire year. These consolidated financial statements should be read in conjunction with the Company’s consolidated financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016 , which was filed with the Securities and Exchange Commission (the “SEC”). Principles of Consolidation The consolidated financial statements include the accounts of the Company, the Operating Partnership and their consolidated subsidiaries. The Company consolidates variable interest entities (“VIE”) where the Company is the primary beneficiary and voting interest entities which are generally majority owned or otherwise controlled by the Company. All significant intercompany balances are eliminated in consolidation. Variable Interest Entities A VIE is an entity that lacks one or more of the characteristics of a voting interest entity. A VIE is defined as an entity in which equity investors do not have the characteristics of a controlling financial interest or do not have sufficient equity at risk for the entity to finance its activities without additional subordinated financial support from other parties. The determination of whether an entity is a VIE includes both a qualitative and quantitative analysis. The Company bases its qualitative analysis on its review of the design of the entity, its organizational structure including decision-making ability and relevant financial agreements and the quantitative analysis on the forecasted cash flow of the entity. The Company reassesses its initial evaluation of an entity as a VIE upon the occurrence of certain reconsideration events. A VIE must be consolidated only by its primary beneficiary, which is defined as the party who, along with its affiliates and agents has both the: (i) power to direct the activities that most significantly impact the VIE’s economic performance; and (ii) obligation to absorb the losses of the VIE or the right to receive the benefits from the VIE, which could be significant to the VIE. The Company determines whether it is the primary beneficiary of a VIE by considering qualitative and quantitative factors, including, but not limited to: which activities most significantly impact the VIE’s economic performance and which party controls such activities; the amount and characteristics of its investment; the obligation or likelihood for the Company or other interests to provide financial support; consideration of the VIE’s purpose and design, including the risks the VIE was designed to create and pass through to its variable interest holders and the similarity with and significance to the business activities of the Company and the other interests. The Company reassesses its determination of whether it is the primary beneficiary of a VIE each reporting period. Significant judgments related to these determinations include estimates about the current and future fair value and performance of investments held by these VIEs and general market conditions. The Company will evaluate its investments to determine whether they are a VIE. The Company analyzes new investments and financings, as well as reconsideration events for existing investments and financings, which vary depending on type of investment or financing. Voting Interest Entities A voting interest entity is an entity in which the total equity investment at risk is sufficient to enable it to finance its activities independently and the equity holders have the power to direct the activities of the entity that most significantly impact its economic performance, the obligation to absorb the losses of the entity and the right to receive the residual returns of the entity. The usual condition for a controlling financial interest in a voting interest entity is ownership of a majority voting interest. If the Company has a majority voting interest in a voting interest entity, the entity will generally be consolidated. The Company does not consolidate a voting interest entity if there are substantive participating rights by other parties and/or kick-out rights by a single party or through a simple majority vote. The Company performs on-going reassessments of whether entities previously evaluated under the voting interest framework have become VIEs, based on certain events, and therefore subject to the VIE consolidation framework. Non-controlling Interests A non-controlling interest in a consolidated subsidiary is defined as the portion of the equity (net assets) in a subsidiary not attributable, directly or indirectly, to the Company. A non-controlling interest is required to be presented as a separate component of equity on the consolidated balance sheets and presented separately as net income (loss) and other comprehensive income (loss) (“OCI”) attributable to non-controlling interests. An allocation to a non-controlling interest may differ from the stated ownership percentage interest in such entity as a result of a preferred return and allocation formula, if any, as described in such governing documents. Estimates The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that could affect the amounts reported in the consolidated financial statements and accompanying notes. Actual results could materially differ from those estimates and assumptions. Reclassifications Certain prior period amounts have been reclassified in the consolidated financial statements to conform to current period presentation. Comprehensive Income (Loss) The Company reports consolidated comprehensive income (loss) in separate statements following the consolidated statements of operations. Comprehensive income (loss) is defined as the change in equity resulting from net income (loss) and OCI. The components of OCI principally include the foreign currency translation adjustment, net. Restricted Cash Restricted cash primarily consists of amounts related to operating real estate such as escrows for taxes, insurance, capital expenditures, tenant security deposits and payments required under certain lease agreements and amounts related to the Company’s borrowings. Operating Real Estate Operating real estate is carried at historical cost less accumulated depreciation. Ordinary repairs and maintenance are expensed as incurred. Major replacements and improvements which extend the life of the asset are capitalized and depreciated over their useful life. Operating real estate is depreciated using the straight-line method over the estimated useful lives of the assets. The Company accounts for purchases of operating real estate that qualify as business combinations using the acquisition method, where the purchase price is allocated to tangible assets such as land, building, tenant and land improvements and other identified intangibles, such as in-place leases, above/below-market leases and goodwill. Costs directly related to an acquisition deemed to be a business combination are expensed and included in transaction costs in the consolidated statements of operations. Operating real estate is depreciated using the straight-line method over the estimated useful lives of the assets, summarized as follows: Category: Term: Building 40 years Building improvements Lesser of the useful life or remaining life of the building Building leasehold interests Lesser of 40 years or remaining term of the lease Tenant improvements Lesser of the useful life or remaining term of the lease Assets and Liabilities Held For Sale Operating real estate which has met the criteria to be classified as held for sale is separately presented on the consolidated balance sheets. Such operating real estate is recorded at the lower of its carrying value or its estimated fair value less the cost to sell net of the intangible assets associated with the asset. Once a property is determined to be held for sale, depreciation is no longer recorded. The Company records a gain or loss on sale of real estate when title is conveyed to the buyer and the Company has no substantial economic involvement with the property. If the sales criteria for the full accrual method are not met, the Company defers some or all of the gain or loss recognition by applying the finance, leasing, profit sharing, deposit, installment or cost recovery method, as appropriate, until the sales criteria are met. Deferred Costs Deferred costs primarily include deferred financing costs and deferred lease costs. Deferred financing costs represent commitment fees, legal and other third-party costs associated with obtaining financing. Costs related to revolving credit facilities are recorded in other assets and are amortized to interest expense using the straight-line basis over the term of the facility. Costs related to other borrowings are recorded net against the carrying value of such borrowings and are amortized into interest expense using the effective interest method or straight-line method depending on the type of financing. Unamortized deferred financing costs are expensed when the associated borrowing is repaid before maturity to realized gain (loss) on sales and other. Costs incurred in seeking financing transactions, which do not close, are expensed in the period in which it is determined that the financing will not occur. Deferred lease costs consist of fees incurred to initiate and renew operating leases, which are amortized on a straight-line basis over the remaining lease term and are recorded to depreciation and amortization in the consolidated statements of operations. Intangible Assets and Intangible Liabilities The Company records acquired identified intangibles, which includes intangible assets (such as value of the above-market leases, in-place leases, below-market ground leases, goodwill and other intangibles) and intangible liabilities (such as the value of below-market leases), based on estimated fair value. The value allocated to the above or below-market leases is amortized net to rental income, the value of below-market ground leases is amortized into properties - operating expense and in-place leases is amortized into depreciation and amortization expense, respectively, in the consolidated statements of operations on a straight-line basis over the respective remaining lease term. Goodwill represents the excess of the purchase price over the fair value of net tangible and intangible assets acquired in a business combination and is not amortized. The Company analyzes goodwill for impairment on an annual basis and whenever events or changes in circumstances indicate that the carrying value of goodwill may not be fully recoverable. The Company first assesses qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit, related to such goodwill, is less than the carrying amount as a basis to determine whether the two-step impairment test is necessary. The first step in the impairment test compares the fair value of the reporting unit with its carrying amount. If the carrying amount exceeds fair value, the second step is required to determine the amount of the impairment loss, if any, by comparing the implied fair value of the reporting unit goodwill with the carrying amount of such goodwill. The implied fair value of goodwill is derived by performing a hypothetical purchase price allocation for the reporting unit as of the measurement date, allocating the reporting unit’s estimated fair value to its net assets and identifiable intangible assets. The residual amount represents the implied fair value of goodwill. To the extent this amount is below the carrying value of goodwill, an impairment loss is recorded in the consolidated statements of operations. The following table presents identified intangibles as of March 31, 2017 and December 31, 2016 (dollars in thousands): March 31, 2017 December 31, 2016 Gross Amount Accumulated Amortization Net Gross Amount Accumulated Amortization Net Intangible assets: In-place lease $ 85,203 $ (32,165 ) $ 53,038 $ 84,743 $ (29,012 ) $ 55,731 Above-market lease 36,549 (9,156 ) 27,393 36,704 (8,198 ) 28,506 Below-market ground lease 51,858 (971 ) 50,887 51,218 (832 ) 50,386 Goodwill (1) 13,997 NA 13,997 13,780 N/A 13,780 Total $ 187,607 $ (42,292 ) $ 145,315 $ 186,445 $ (38,042 ) $ 148,403 Intangible liabilities: Below-market lease $ 34,637 $ (9,152 ) $ 25,485 $ 34,163 $ (8,104 ) $ 26,059 Above-market ground lease 4,917 (114 ) 4,803 4,839 (96 ) 4,743 Total $ 39,554 $ (9,266 ) $ 30,288 $ 39,002 $ (8,200 ) $ 30,802 _______________________ (1) Represents goodwill associated with certain share-deal acquisitions in exchange for shares in the underlying portfolios. The goodwill and a corresponding deferred tax liability was recorded at acquisition based on tax basis differences. Other Assets and Other Liabilities The following tables present a summary of other assets and other liabilities as of March 31, 2017 and December 31, 2016 (dollars in thousands): March 31, 2017 December 31, 2016 Other assets: Prepaid expenses $ 2,966 $ 1,951 Deferred costs, net 2,880 3,029 Deferred tax assets, net 244 — Straight-line rent 11,560 10,182 Escrow receivable 4,968 6,168 Other 247 310 Total $ 22,865 $ 21,640 March 31, 2017 December 31, 2016 Other liabilities: Deferred tax liabilities $ 9,066 $ 8,916 Prepaid rent received and unearned revenue 15,329 13,585 Tenant security deposits 4,526 4,322 Prepaid escalation income 1,734 1,560 Other 540 535 Total $ 31,195 $ 28,918 Revenue Recognition Operating Real Estate Rental and escalation income from operating real estate is derived from leasing of space to various types of tenants. Rental revenue recognition commences when the tenant takes possession of the leased space and the leased space is substantially ready for its intended use. The leases are for fixed terms of varying length and generally provide for annual rentals, subject to indexation, and expense reimbursements to be paid in quarterly or monthly installments. Rental income from leases is recognized on a straight-line basis over the term of the respective leases. The excess of rents recognized over amounts contractually due pursuant to the underlying leases are included in other assets, net on the consolidated balance sheets. The Company amortizes any tenant inducements as a reduction of revenue utilizing the straight-line method over the term of the lease. Escalation income represents revenue from tenant leases which provide for the recovery of all or a portion of the operating expenses and real estate taxes paid by the Company on behalf of the respective property. This revenue is accrued in the same period as the expenses are incurred. In a situation in which a lease or leases associated with a significant tenant have been, or are expected to be, terminated early, the Company evaluates the remaining useful life of depreciable or amortizable assets in the asset group related to the lease that will be terminated (i.e., tenant improvements, above and below market lease intangibles, in-place lease value and leasing commissions). Based upon consideration of the facts and circumstances surrounding the termination, the Company may write-off or accelerate the depreciation and amortization associated with the asset group. Such amounts are included within depreciation and amortization in the consolidated statements of operations. Impairment on Investments Operating Real Estate The Company’s real estate portfolio is reviewed on a quarterly basis, or more frequently as necessary, to assess whether there are any indicators that the value of its operating real estate may be impaired or that its carrying value may not be recoverable. A property’s value is considered impaired if the Company’s estimate of the aggregate expected future undiscounted cash flow to be generated by the property is less than the carrying value of the property. In conducting this review, the Company considers global macroeconomic factors, real estate sector conditions, together with investment specific and other factors. To the extent an impairment has occurred, the loss is measured as the excess of the carrying value of the property over the estimated fair value of the property and recorded in impairment losses in the consolidated statements of operations. For the three months ended March 31, 2017 and 2016 , the Company did not recognize any impairment losses. An allowance for a doubtful account for a tenant receivable is established based on a periodic review of aged receivables resulting from estimated losses due to the inability of a tenant to make required rent and other payments contractually due. Additionally, the Company establishes, on a current basis, an allowance for future tenant credit losses on unbilled rent receivable based on an evaluation of the collectability of such amounts. Equity-Based Compensation The Company accounts for equity-based compensation awards using the fair value method, which requires an estimate of fair value of the award. Awards may be based on a variety of measures such as time, performance, market or a combination thereof. For time-based awards, fair value is determined based on the stock price on the grant date. The Company recognizes compensation expense over the vesting period on a straight-line basis or the attribution method depending if the grant is to an employee or non-employee. For performance-based awards, fair value is determined based on the stock price at the date of grant and an estimate of the probable achievement of such measure. The Company recognizes compensation expense over the requisite service period, net of estimated forfeitures, using the accelerated attribution expense method. For market-based measures, fair value is determined using a Monte Carlo analysis under a risk-neutral premise using a risk-free interest rate. The Company recognizes compensation expense, over the requisite service period, net of estimated forfeitures, on a straight-line basis. For awards with a combination of performance or market measures, the Company estimates the fair value as if it were two separate awards. First, the Company estimates the probability of achieving the performance measure. If it is not probable the performance condition will be met, the Company records the compensation expense based on the fair value of the market measure, as described above. This expense is recorded even if the market-based measure is never met. If the performance-based measure is subsequently estimated to be achieved, the Company records compensation expense based on the performance-based measure. The Company would then record a cumulative catch-up adjustment for any additional compensation expense. Equity-based compensation issued to non-employees is accounted for using the fair value of the award at the earlier of the performance commitment date or performance completion date. Time-based awards are remeasured every quarter based on the stock price as of the end of the reporting period until such awards vest, if any. Derivatives The Company seeks to use derivative instruments to manage exposure to interest rate risk and foreign currency exchange rate risk. The change in fair value for a derivative is recorded in unrealized gain (loss) on derivatives and other in the consolidated statements of operations. The Company’s derivative instruments are recorded on the consolidated balance sheets at fair value and do not qualify as hedges under U.S. GAAP. Foreign Currency Assets and liabilities denominated in a foreign currency for which the functional currency is a foreign currency are translated using the currency exchange rate in effect at the end of the period presented and the results of operations for such entities are translated into U.S. dollars using the average currency exchange rate in effect during the period. The resulting foreign currency translation adjustment (“CTA”), net, is recorded as a component of accumulated OCI in the consolidated statements of equity. For the three months ended March 31, 2017 and 2016 , the Company reclassified $0.4 million of CTA to realized gain (loss) on sales and other in the consolidated statements of operations due to the sale of certain real estate assets (refer to Note 3). Assets and liabilities denominated in a foreign currency for which the functional currency is the U.S. dollar are remeasured using the currency exchange rate in effect at the end of the period presented and the results of operations for such entities are remeasured into U.S. dollars using the average currency exchange rate in effect during the period. The resulting foreign currency remeasurement adjustment is recorded in unrealized gain (loss) on derivatives and other in the consolidated statements of operations. Earnings Per Share The Company’s basic earnings per share (“EPS”) is calculated by dividing net income (loss) attributable to common stockholders by the weighted average number of common stock outstanding. Diluted EPS includes restricted stock and the potential dilution that could occur if outstanding restricted stock units (“RSUs”) or other contracts to issue common stock, assuming performance hurdles have been met, were converted to common stock (including limited partnership interests in the Operating Partnership owned by holders other than the Company (“Common Units”) and Common Units which are structured as profits interests (“LTIP Units” collectively referred to as Unit Holders) (refer to Note 7), where such exercise or conversion would result in a lower EPS. The dilutive effect of such RSUs and Unit Holders is calculated assuming all units are converted to common stock. Income Taxes The Company has elected to be taxed as a REIT for U.S. federal income tax purposes and will continue to comply with the related provisions of the Internal Revenue Code of 1986, as amended, the (“Internal Revenue Code”). Accordingly, the Company generally will not be subject to U.S. federal income tax to the extent of its distributions to stockholders and as long as certain asset, income and share ownership tests are met. To maintain its qualification as a REIT, the Company must annually distribute at least 90% of its REIT taxable income to its stockholders and meet certain other requirements. Under certain circumstances, federal income and excise taxes may be due on its undistributed taxable income. The Company distributes to its stockholders 100% of its taxable income and therefore no provision for U.S. federal income taxes has been included in the accompanying consolidated financial statements for the three months ended March 31, 2017 and 2016 . Dividends distributed for the three months ended March 31, 2017 and 2016 were characterized, for U.S. federal income tax purposes, as ordinary income. The Company conducts its business through foreign subsidiaries which may be subject to local level income tax in the European jurisdictions it operates. The Company has also elected taxable REIT subsidiary (“TRS”) status for one of the Company’s foreign subsidiaries. This enables the Company to provide services that would otherwise be considered impermissible for REITs and participate in activities that do not qualify as “rents from real property.” The TRS is not resident in the U.S. and, as such, not subject to U.S. taxation but is subject to foreign income taxes only. In addition, the REIT will not generally be subject to any additional U.S. taxes on the repatriation of its earnings. For the Company’s foreign subsidiaries, including the Company’s foreign TRS, deferred tax assets and liabilities are established for temporary differences between the financial reporting basis and the foreign tax basis of assets and liabilities at the enacted tax rates expected to be in effect when the temporary differences reverse. The Company evaluates the realizability of its deferred tax assets (e.g. net operating loss) and recognizes a valuation allowance if, based on the available evidence, it is more likely than not that some portion or all of its deferred tax assets will not be realized. When evaluating the realizability of its deferred tax assets, the Company considers estimates of expected future taxable income, existing and projected book/tax differences, tax planning strategies available and the general and industry specific economic outlook. This realizability analysis is inherently subjective, as it requires the Company to forecast its business and general economic environment in future periods. Due to past and projected losses in certain local jurisdictions where the Company does not have carryback potential and/or cannot sufficiently forecast future taxable income, the Company recognized net cumulative valuation allowances against the Company’s deferred tax assets. The Company will continue to review its deferred tax assets in accordance with U.S. GAAP. The Company recorded an income tax benefit for the three months ended March 31, 2017 and 2016 of $0.3 million and $0.7 million , respectively. Other Refer to Note 2 of the consolidated financial statements in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2016 for further disclosure of the Company’s significant accounting policies. Recent Accounting Pronouncements In May 2014, the Financial Accounting Standards Board (“FASB”) issued an accounting update requiring a company to recognize as revenue the amount of consideration it expects to be entitled to in connection with the transfer of promised goods or services to customers. The accounting standard update will replace most of the existing revenue recognition guidance currently promulgated by U.S. GAAP. In July 2015, the FASB decided to delay the effective date of the new revenue standard by one year. The effective date of the new revenue standard for the Company will be January 1, 2018. Leases are specifically excluded from this guidance and will be governed by the applicable lease codification; however, this update may have implications in certain variable payment terms included in lease agreements and in sale and leaseback transactions. The Company is in the process of evaluating the impact, if any, of the update on its consolidated financial position, results of operations and financial statement disclosures In February 2016, the FASB issued an accounting update that sets out the principles for the recognition, measurement, presentation and disclosure of leases for both parties to a contract (i.e., lessees and lessors). The update requires lessees to apply a dual approach, classifying leases as either finance or operating leases based on the principle of whether or not the lease is effectively a financed purchase of the leased asset by the lessee. This classification will determine whether the lease expense is recognized based on an effective interest method or on a straight-line basis over the term of the lease. A lessee is also required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months regardless of their classification. Leases with a term of 12 months or less will be accounted for similar to existing guidance for operating leases today. The update is expected to result in the recognition of a right-to-use asset and related liability to account for the Company’s future obligations under its ground lease arrangements for which it is the lessee. As of March 31, 2017, the Company has three ground lease agreements with annual payments of $0.6 million . Additionally, the new update will require that lessees and lessors capitalize, as initial direct costs, only those costs that are incurred due to the execution of a lease. Under this guidance, allocated payroll costs and other costs that are incurred regardless of whether the lease is obtained will no longer be capitalized as initial direct costs and instead will be expensed as incurred. Lessors will continue to account for leases using an approach that is substantially equivalent to existing guidance for sales-type leases, direct financing leases and operating leases. The new guidance is to be applied using a modified retrospective approach at the beginning of the earliest comparative period in the financial statements and is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. The Company is evaluating the impact, if any, that this guidance will have on its consolidated financial position, results of operations and financial statement disclosures. In March 2016, the FASB issued guidance clarifying that an assessment of whether an embedded contingent put or call option is clearly and closely related to a borrowing requires only an analysis of the four-step decision sequence. Additionally, entities are not required to separately assess whether the contingency itself is clearly and closely related. Entities are required to apply the guidance to existing instruments in scope using a modified retrospective transition method as of the period of adoption. The guidance is effective for fiscal years beginning after December 15, 2016 and interim periods within those years. The Company has adopted this guidance and it did not have any material impact on its consolidated financial position, results of operations and financial statement disclosures. In March 2016, the FASB issued guidance which amends several aspects of the accounting for equity-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities and classification on the statements of cash flows. The guidance is effective for interim and annual reporting periods in fiscal years beginning after December 15, 2016. The Company has adopted this guidance and it did not have a material impact on its consolidated financial position, results of operations and financial statement disclosures. In June 2016, the FASB issued guidance that changes the impairment model for most financial instruments by requiring companies to recognize an allowance for expected losses, rather than incurred losses as required currently by the other-than-temporary impairment model. The guidance will apply to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities, net investments in leases and off-balance-sheet credit exposures (e.g., loan commitments). The new guidance is effective for reporting periods beginning after December 15, 2019 and will be applied as a cumulative adjustment to retained earnings as of the effective date. The Company is evaluating the impact, if any, that this guidance will have on its consolidated financial position, results of operations and financial statement disclosures. In August 2016, the FASB issued guidance that makes eight targeted changes to how cash receipts and cash payments are presented and classified in the statement of cash flows. The guidance is effective for fiscal years beginning after December 15, 2017 and interim periods within those fiscal years. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The new guidance requires adoption on a retrospective basis unless it is impracticable to apply, in which case the Company would be required to apply the amendments prospectively as of the earliest date practicable. The Company does not expect the adoption of this standard to have a material impact on its consolidated statements of cash flows. In November 2016, the FASB issued guidance which requires entities to show the changes in the total of cash and cash equivalents and restricted cash and restricte |
