Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION Hines Global REIT, Inc. (the “Company”), was formed as a Maryland corporation on December 10, 2008 under the General Corporation Law of the state of Maryland for the purpose of engaging in the business of investing in and owning commercial real estate properties and other real estate investments. The Company conducts substantially all of its operations through Hines Global REIT Properties, LP (the “Operating Partnership”) and subsidiaries of the Operating Partnership. Beginning with its taxable year ended December 31, 2009, the Company operated and intends to continue to operate in a manner to qualify as a real estate investment trust (“REIT”) for federal income tax purposes. The day-to-day business of the Company is managed by Hines Global REIT Advisors LP (the “Advisor”), an affiliate of Hines Interests Limited Partnership (“Hines”), pursuant to the Advisory Agreement between the Company, the Advisor and the Operating Partnership. On August 5, 2009 , the Company commenced its initial public offering of common stock for sale to the public (the “Initial Offering”) which expired on February 1, 2013 . The Company commenced a follow-on offering effective February 4, 2013 , through which it offered up to $3.5 billion in shares of common stock (the “Second Offering”), and ceased offering primary shares pursuant to the second public offering on April 11, 2014 . The Company continues to offer up to $500.0 million of shares of its common stock under its distribution reinvestment plan, pursuant to an offering which commenced on April 24, 2014 (the “DRP Offering”). Collectively, through its public offerings, the Company received gross offering proceeds of $3.1 billion from the sale of 306.7 million shares from inception through December 31, 2017 , all of which has been invested in the Company’s real estate portfolio. By the end of 2015, the Company completed its investment of the proceeds raised through its public offerings and owned interests in 43 real estate investments. Since that time, through December 31, 2017 , the Company has sold its interests in 9 real estate investments. As of December 31, 2017 , the Company owned interests in 34 real estate investments, consisting of the following types of investments: • Domestic office investments ( 9 investments) • Domestic other investments ( 5 investments) • International office investments ( 9 investments) • International other investments ( 11 investments) Joint Ventures, Equity Method Investments and Noncontrolling Interests On January 7, 2009, the Company and Hines Global REIT Associates Limited Partnership (“HALP”), an affiliate of the Advisor, formed Hines Global REIT Properties, LP (the “Operating Partnership”). The Company conducts most of its operations through the Operating Partnership. On January 14, 2009, the Company and HALP made initial capital contributions to the Operating Partnership of $10,000 and $190,000 , respectively and accordingly, HALP owned a 95.0% noncontrolling interest in the Operating Partnership. As of December 31, 2017 and 2016 , HALP owned a 0.01% and 0.01% interest in the Operating Partnership, respectively. The Brindleyplace JV In June 2010, the Operating Partnership and Moorfield Real Estate Fund II GP Ltd., (“Moorfield”) formed Hines Moorfield UK Venture I S.A.R.L., (the “Brindleyplace JV”) and, in July 2010, the Brindleyplace JV acquired several properties located in Birmingham, England (the “Brindleyplace Project”). In 2015, LSREF 3 Laser Holdings (Jersey) Limited (“Laser”) purchased Moorfield’s interest in the Brindleyplace JV and renamed it Hines Laser UK Venture I S.A.R.L. The Company owned a 60% interest in the Brindleyplace JV and Laser held the remaining 40% interest. In February 2017 , the Brindleyplace JV sold the Brindleyplace Project. See Note 3 — Investment Property for information regarding the sale. The Company has concluded its investment in the Brindleyplace JV does not qualify as a variable interest entity (“VIE”) under the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC” or the “Codification”) 810 “Consolidation.” Based on the Company’s majority voting interest as well as certain additional voting rights and other factors, the Company has consolidated the Brindleyplace JV and its wholly-owned subsidiaries in its financial statements. See Note 10 — Noncontrolling Interests for additional information regarding our noncontrolling interests in the Brindleyplace JV. Consolidated VIEs The Flagship JV In June 2011, a wholly-owned subsidiary of the Operating Partnership entered into a Limited Partnership Agreement (as amended) with Flagship Capital, GP for the formation of Flagship Capital Partners Fund, LP (the “Flagship JV”) for the purpose of originating real estate loans. The Company owns a 97% interest in the Flagship JV and Flagship Capital, GP owns the remaining 3% interest. Flagship Capital, GP serves as the general partner and will manage the day-to-day activities of the Flagship JV. Both partners have equal voting rights and distributions from the Flagship JV will initially be paid to the fund partners based on their pro rata ownership. Since the voting rights of each of the partners are disproportionate to their ownership interests, the Company has concluded that the Flagship JV qualifies as a VIE under ASC 810. Further, the Company has determined that it is the primary beneficiary due to its ability to exercise significant control and influence over the Flagship JV as well as certain other factors. As a result, the Company consolidated the Flagship JV and its wholly-owned subsidiaries in its financial statements. See Note 10 — Noncontrolling Interests for additional information regarding our noncontrolling interests in the Flagship JV. As of December 31, 2017 , there were no remaining real estate loans owned by the Flagship JV and the partners consented to the voluntary winding up and termination of the Flagship JV. The WaterWall Place JV In December 2011, a wholly-owned subsidiary of the Operating Partnership entered into a Limited Partnership Agreement with an affiliate of Hines for the formation of Hines One WaterWall Holdings LP (the “WaterWall Place JV”), a Delaware limited liability company, for the purpose of developing a residential/living project in Houston, Texas. Hines serves as the initial general partner and as the development partner and the subsidiary of the Operating Partnership is the initial limited partner. The Company has a 93% interest in this joint venture. An affiliate of Hines owns the remaining 7% interest in this joint venture. The Company has concluded its investment in the WaterWall Place JV qualifies as a VIE under ASC 810. Further, the Company has determined that it is the primary beneficiary since it has greater exposure to the variability of One WaterWall JV’s economic performance as well as certain other factors. As a result, the Company has consolidated the WaterWall Place JV and its wholly-owned subsidiaries in its financial statements. See Note 10 — Noncontrolling Interests for additional information regarding our noncontrolling interests in the WaterWall Place JV. The Aviva Coral Gables JV In July 2012, a wholly-owned subsidiary of the Operating Partnership entered into a Limited Partnership Agreement with an affiliate of Hines for the formation of Hines Ponce & Bird Holdings LP, a Delaware limited liability company, for the purpose of developing a residential/living project in Miami, Florida. Hines serves as the initial general partner and as the development partner and the subsidiary of the Operating Partnership is the initial limited partner. The Company had an 83% interest in this joint venture. An affiliate of Hines owned the remaining 17% interest in this joint venture. The Company concluded its investment in the Aviva Coral Gables JV qualified as a VIE under ASC 810. Further, the Company determined that it is the primary beneficiary since it has greater exposure to the variability of Aviva Coral Gables's economic performance as well as certain other factors. As a result, the Company consolidated the Aviva Coral Gables JV and its wholly-owned subsidiaries in its financial statements. In June 2017 , the Aviva Coral Gables JV sold Aviva Coral Gables. See Note 10 — Noncontrolling Interests for additional information regarding our noncontrolling interests in the Aviva Coral Gables JV and see Note 3 — Investment Property for information regarding the sale of the property. A summary of our consolidated VIEs is as follows (in thousands): December 31, 2017 December 31, 2016 Maximum risk of loss (1) $ 9,535 $ 30,446 Assets held by VIEs $ 59,112 $ 136,705 Assets held as collateral for debt $ 59,112 $ 136,705 Liabilities held by VIEs $ 48,222 $ 91,792 (1) Represents the Company's contributions, net of distributions, made to the consolidated VIEs. Restrictions on the use of these assets are significant because they serve as collateral for the VIE’s debt, and the Company is generally required to obtain its partners’ approval in accordance with the respective joint venture agreements for any major transactions. Transactions with these joint ventures on the Company’s consolidated financial statements primarily relate to (i) distributions related to the receipt of proceeds from the collection of loans receivable at the Flagship JV or (ii) distributions received from the WaterWall Place JV and the Aviva Coral Gables JV, respectively. The Company and its partners are subject to the terms of the joint venture agreements which include provisions for when additional contributions may be required. During the year ended December 31, 2017 , the Company received distributions of $52.5 million , which included a $35.3 million distribution from the sale of Aviva Coral Gables in June 2017 and $14.5 million of distributions related to the collection of the remaining loans receivable at the Flagship JV in 2017, net of contributions made of $0.5 million in accordance with the Company’s respective joint venture agreements. During the year ended December 31, 2016 , the Company received distributions of $21.9 million , net of contributions made of $0.2 million in accordance with the Company’s respective joint venture agreements. This activity is eliminated in consolidation of the VIEs, but increases, or decreases in the case of distributions received, the Company’s maximum risk of loss. Unconsolidated VIEs The 1377 Equity Method Investment The Company formed a joint venture with an affiliate of Hines in 2011 related to the construction of 1377, a residential/living development project in Atlanta, Georgia. The Company provided a preferred equity investment in the partnership of $3.6 million during 2012, representing a 51.7% ownership in the project and a $3.2 million mezzanine loan commitment plus accrued interest made by the Company. In addition, the partnership obtained a $23.3 million secured loan made by Cadence Bank, N.A., which was solely guaranteed by the Company’s joint venture partner (the “JV Partner”). The Company concluded that 1377 qualifies as a VIE. The JV Partner was the manager of the project, which allowed the JV Partner to direct the activities of the VIE that most significantly impacted the VIE’s financial performance. Based upon the loan guarantees and the JV Partner’s ability to direct the activities that significantly impacted the economic performance of the VIE, the Company determined that it is not the primary beneficiary of this VIE and determined to account for its preferred equity investment in the project as an equity method investment. Other than the initial capital contributions provided by the Company, the Company did not provide any additional subordinated financial support. The construction of 1377 was completed in March 2014 and in June 2016, the joint venture sold 1377 for $51.0 million , excluding transaction costs and closing prorations. As a result of the sale of the property, the Company’s equity in earnings of the partnership included a gain of $7.5 million and the Company received distributions of $8.7 million as well as $4.0 million related to the repayment of its mezzanine loan.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Use of Estimates The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of the consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities and contingencies as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The Company evaluates its assumptions and estimates on an ongoing basis. The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. Additionally, application of the Company’s accounting policies involves exercising judgments regarding assumptions as to future uncertainties. Actual results may differ from these estimates under different assumptions or conditions. Basis of Presentation The consolidated financial statements of the Company include the accounts of Hines Global REIT, Inc., the Operating Partnership and its wholly-owned subsidiaries and the joint ventures as well as amounts related to noncontrolling interests. All intercompany balances and transactions have been eliminated in consolidation. The Company evaluates the need to consolidate joint ventures in accordance with GAAP. In accordance with GAAP, the Company will consolidate joint ventures that are determined to be variable interest entities for which it is the primary beneficiary. Further, partially owned real estate joint ventures over which the Company has a controlling financial interest are consolidated in its financial statements. In determining if the Company has a controlling financial interest, it considers factors such as ownership interest, authority to make decisions, kick-out rights and substantive participating rights. Management continually analyzes and assesses reconsideration events, including changes in these factors, to determine if the consolidation treatment remains appropriate. Partially owned real estate joint ventures where the Company does not have a controlling financial interest, but has the ability to exercise significant influence, are accounted for using the equity method. The Company’s investments in partially owned real estate joint ventures are reviewed for impairment periodically if events or circumstances change indicating that the carrying amount of its investments may not be recoverable. In such an instance, the Company will record an impairment charge if it determines that a decline in the value of an investment below its fair value is other than temporary. The Company’s analysis will be dependent on a number of factors, including the performance of each investment, current market conditions, and its intent and ability to hold the investment to full recovery. As of December 31, 2017 and 2016 , the Company no longer had any investments in unconsolidated partially owned real estate joint ventures. Based on the Company’s analysis of the facts and circumstances at each reporting period, no impairment was recorded related to its investments in partially owned real estate joint ventures for the years ended December 31, 2017 , 2016 or 2015 . International Operations The British pound (“GBP”) is the functional currency for the Company’s subsidiaries operating in the United Kingdom, the Russian rouble (“RUB”) is the functional currency for the Company’s subsidiaries operating in Russia, the Polish zloty (“PLN”) is the functional currency for the Company’s subsidiaries operating in Poland, the Australian dollar (“AUD”) is the functional currency for the Company’s subsidiaries operating in Australia and the Euro (“EUR”) is the functional currency for the Company’s subsidiaries operating in Germany and France. These subsidiaries have translated their financial statements into U.S. dollars for reporting purposes. Assets and liabilities are translated at the exchange rate in effect as of the balance sheet date while income statement accounts are translated using the average exchange rate for the period and significant nonrecurring transactions using the rate on the transaction date. Gains or losses resulting from translation are included in accumulated other comprehensive income (loss) within stockholders’ equity. Foreign currency transaction gains and losses are recorded in foreign currency gains (losses) on the consolidated statement of operations and result from the effect of changes in exchange rates on transactions denominated in currencies other than a subsidiary’s functional currency, including transactions between consolidated subsidiaries. An exception is made where an intercompany loan or advance is deemed to be of a long-term investment nature, in which instance foreign currency transaction gains or losses are included as currency translation adjustments and are reported in the consolidated statement of equity as accumulated other comprehensive gains or losses. The Company disposed of its investment in the Brindleyplace Project in February 2017 as well as its investment in Mercedes Benz Bank in July 2017 . Upon the disposal of these properties, the Company realized a loss of $8.8 million related to the currency translation adjustment, which was included in the gain (loss) on sale of real estate in its consolidated statement of operations. During the year ended December 31, 2015, intercompany loans with the consolidated subsidiaries in Australia were repaid and as a result, the Company recognized a loss of $15.1 million , which was included in foreign currency gain (loss). Investment Property and Lease Intangibles Real estate assets acquired by the Company are stated at fair value at the date of acquisition less accumulated depreciation. Depreciation is computed using the straight-line method. The estimated useful lives for computing depreciation are generally 10 years for furniture and fixtures, 15 - 20 years for electrical and mechanical installations and 40 years for buildings. Major replacements that extend the useful life of the assets are capitalized and maintenance and repair costs are expensed as incurred. Acquisitions of properties are accounted for utilizing the acquisition method and, accordingly, are recorded at the estimated fair values of the assets acquired and liabilities assumed. The results of operations of acquired properties are included in the Company’s results of operations from their respective dates of acquisition. Estimates of fair values are based upon estimates of future cash flows and other valuation techniques that the Company believes are similar to those used by market participants and are used to record the purchase of identifiable assets acquired, such as land, buildings and improvements, equipment and identifiable intangible assets related to in-place leases and liabilities assumed, such as amounts related to acquired out-of-market leases, asset retirement obligations, mortgage notes payable. Values of buildings and improvements are determined on an as if vacant basis. Initial valuations are subject to change until such information is finalized, no later than 12 months from the acquisition date. For prior acquisitions, acquisition-related costs such as transaction costs and acquisition fees paid to the Advisor were expensed as incurred. Beginning in 2018, when Accounting Standards Update (“ASU”) 2017-01 becomes effective, any acquisition-related costs and acquisition fees to any future acquisitions will be capitalized. See Recent Accounting Pronouncements below for more information on ASU 2017-01. The estimated fair value of acquired in-place leases are the costs the Company would have incurred to lease the properties to the occupancy level of the properties at the date of acquisition. Such estimates include the fair value of leasing commissions, legal costs and other direct costs that would be incurred to lease the properties to such occupancy levels. Additionally, the Company evaluates the time period over which such occupancy levels would be achieved. Such evaluation will include an estimate of the net market-based rental revenues and net operating costs (primarily consisting of real estate taxes, insurance and utilities) that would be incurred during the lease-up period. Acquired in-place leases as of the date of acquisition are amortized over the remaining lease terms. Should a tenant terminate its lease, the unamortized portion of the in-place lease value is charged to amortization expense. Acquired out-of-market lease values (including ground leases) are recorded based on the present value (using a discount rate that reflects the risks associated with the lease acquired) of the difference between the contractual amounts paid pursuant to the in-place leases and management’s estimate of fair market value lease rates for the corresponding in-place leases. The capitalized out-of-market lease values are amortized as adjustments to rental revenue (or ground lease expense, as applicable) over the remaining terms of the respective leases, which include periods covered by bargain renewal options. Should a tenant terminate its lease, the unamortized portion of the out-of-market lease value is charged to rental revenue. Management estimates the fair value of assumed mortgage notes payable based upon indications of then-current market pricing for similar types of debt with similar maturities. Assumed mortgage notes payable are initially recorded at their estimated fair value as of the assumption date, and the difference between such estimated fair value and the outstanding principal balance of the note will be amortized over the life of the mortgage note payable. Real estate assets are reviewed for impairment each reporting period if events or changes in circumstances indicate that the carrying amount of the individual property may not be recoverable. In such an event, a comparison will be made of the current and projected operating cash flows and expected proceeds from the eventual disposition of each property on an undiscounted basis to the carrying amount of such property. If the carrying amount exceeds the undiscounted cash flows, it would be written down to the estimated fair value to reflect impairment in the value of the asset. The determination of whether investment property is impaired requires a significant amount of judgment by management and is based on the best information available to management at the time of the evaluation. For the year ended December 31, 2017 , we determined that one of our investment properties was impaired as a result of deteriorating market conditions. As a result, an impairment loss of $7.1 million was recorded to write down its carrying value to its fair value for the year ended December 31, 2017 . No impairment charges were recorded during the years ended December 31, 2016 , and 2015 . Cash and Cash Equivalents The Company considers all short-term, highly liquid investments that are readily convertible to cash with an original maturity of three months or less at the time of purchase to be cash equivalents. Restricted Cash The Company has restricted cash primarily related to certain escrow accounts required by several of the Company’s mortgage agreements. Concentration of Credit Risk As of December 31, 2017 , the Company had cash and cash equivalents and restricted cash deposited in certain financial institutions in excess of federally insured levels. Management regularly monitors the financial stability of these financial institutions in an effort to manage the Company’s exposure to any significant credit risk in cash and cash equivalents or restricted cash. In addition, as of December 31, 2017 , the Company had $74.9 million of cash and cash equivalents deposited in certain financial institutions located in the United Kingdom, Russia, Poland, Australia, Germany, and France. Management regularly monitors the financial stability of these financial institutions in an effort to manage its exposure to any significant credit risk in cash and cash equivalents. Tenant and Other Receivables Receivable balances consist primarily of base rents, tenant reimbursements and receivables attributable to straight-line rent. An allowance for the uncollectible portion of tenant and other receivables is determined based upon an analysis of 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. Tenant and other receivables are shown at cost in the consolidated balance sheets, net of allowance for doubtful accounts of $3.8 million and $2.5 million at December 31, 2017 and 2016 , respectively. Deferred Leasing Costs Direct leasing costs, primarily consisting of third-party leasing commissions, tenant inducements and legal costs are capitalized and amortized over the life of the related lease. Tenant inducement amortization is recorded as an offset to rental revenue and the amortization of other direct leasing costs is recorded in amortization expense. Tenant inducement amortization was $18.7 million , $12.3 million and $7.6 million for the years ended December 31, 2017 , 2016 and 2015 , respectively, and was recorded as an offset to rental revenue. In addition, the Company recorded $4.6 million , $4.0 million and $2.5 million as amortization expense related to other direct leasing costs for the years ended December 31, 2017 , 2016 and 2015 , respectively. Deferred Financing Costs Deferred financing costs consist of direct costs incurred in obtaining debt financing (see Note 6 - Debt Financing). These fees are presented as a reduction to the related debt liability for permanent mortgages and presented as an asset for revolving credit arrangements. In total, deferred financing costs (net of amortization) were $6.5 million and $10.8 million as of December 31, 2017 and 2016 . These costs are amortized into interest expense on a straight-line basis, which approximates the effective interest method, over the terms of the obligations. For the years ended December 31, 2017 , 2016 and 2015 , $4.7 million , $5.0 million and $6.0 million , were amortized into interest expense in the accompanying consolidated statement of operations, respectively. Real Estate Loans Receivable Real estate loans receivable are shown at cost, net of any applicable allowance for uncollectibility and net of deferred loan origination fees. The Company defers certain loan origination fees and amortizes them as an adjustment of yield over the term of the related real estate loan receivable. The related amortization of the deferred loan origination fees are recorded in other revenue in the accompanying consolidated statement of operations and comprehensive income (loss). An allowance for the uncollectible portion of the real estate loans receivable is determined based upon an analysis of the economic conditions in the area in which the property is located and credit quality indicators which include: borrower’s payment history, the financial condition of the borrower, and business conditions in the industry in which the borrower operates. Additionally, a real estate loan receivable is considered to be impaired, when based upon current events, it is probable that we will be unable to collect all amounts due according to the existing contractual terms. If a real estate loan receivable is considered to be impaired, the amount of loss is calculated by comparing the recorded investment to the value determined by discounting the expected future cash flows at its effective interest rate or to the value of the underlying collateral if the real estate loan receivable is collateral dependent. Evaluating real estate loans receivable for potential impairment can require management to exercise significant judgment. No impairment was recorded for the years ended December 31, 2017 , 2016 and 2015 , respectively. Further, as of December 31, 2016 , no allowances for uncollectibility have been recorded. As of December 31, 2017 , the Company had no outstanding loan receivable balances. Other Assets Other assets included the following (in thousands): December 31, 2017 December 31, 2016 Prepaid expenses 3,021 2,647 Deferred tax assets (1) 26,670 11,259 Other (2) 407 6,454 Other assets $ 30,098 $ 20,360 (1) The change in deferred tax assets is primarily due to a $13.1 million increase caused by the restructuring of certain of the Company’s Polish subsidiaries as a result of the recent tax law changes in Poland. (2) Primarily consists of $6.3 million held by our escrow agent at Perspective Defense as of December 31, 2016. This amount was returned to the Company in January 2017. Revenue Recognition Rental payments are generally paid by the tenants prior to the beginning of each month. As of December 31, 2017 and December 31, 2016 , respectively, the Company recorded liabilities of $16.7 million and $27.3 million related to prepaid rental payments which were included in other liabilities in the accompanying consolidated balance sheets. The Company recognizes rental revenue on a straight-line basis over the life of the lease including rent holidays, if any. Straight-line rent receivable was $53.9 million and $89.4 million as of December 31, 2017 and December 31, 2016 , respectively. Straight-line rent receivable consists of the difference between the tenants’ rents calculated on a straight-line basis from the date of acquisition or lease commencement over the remaining terms of the related leases and the tenants’ actual rents due under the lease agreements and is included in tenant and other receivables in the accompanying consolidated balance sheets. Revenues associated with operating expense recoveries are recognized in the period in which the expenses are incurred based upon the tenant lease provisions. Revenues relating to lease termination fees are recognized on a straight-line basis amortized from the time that a tenant’s right to occupy the leased space is modified through the end of the revised lease term. Other revenues consist primarily of parking revenue, tenant reimbursements and interest on loans receivable. Parking revenue represents amounts generated from contractual and transient parking and is recognized in accordance with contractual terms or as services are rendered. Other revenues relating to tenant reimbursements are recognized in the period that the expense is incurred. Income Taxes The Company has elected to be treated as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). The Company’s management believes that it operates in such a manner as to qualify for treatment as a REIT and intends to operate in the foreseeable future in such a manner so that it will remain qualified as a REIT for federal income tax purposes. Accordingly, no provision has been made for U.S. federal income taxes for the years ended December 31, 2017 , 2016 and 2015 in the accompanying consolidated financial statements. In 2017 , 2016 and 2015 , income tax expense recorded by the Company was primarily comprised of foreign income taxes related to the operation its international properties. The Company does not believe it has any uncertain tax positions or unrecognized tax benefits requiring disclosure. On December 22, 2017, the U.S. government enacted the Tax Cuts and Jobs Act. The Tax Cuts and Jobs Act makes broad and complex changes to the Internal Revenue Code including, but not limited to, (1) reducing the top U.S. federal corporate income tax rate from 35% to 21%, (2) establishing a 20% deduction for ordinary REIT dividends (other than any portion that is a capital gain dividend or qualified dividend income, subject to complex limitations), (3) limiting the deductibility of business interest expenses, (4) allowing full expensing of certain qualifying property, (5) eliminating the corporate Alternative Minimum Tax (“AMT”) and changing how existing AMT credits can be realized, (6) limiting current net operating loss deductions and providing an indefinite carryforward and (7) limiting the deductibility of certain executive compensation. The Company’s evaluation of deferred taxes and the associated valuation allowance includes an estimate of the impact of the Tax Cuts and Jobs Act and was based on the best information available to the Company at the time. Redemption of Common Stock The Company complies with Financial Accounting Standards Board (“FASB”) ASC 480 “Distinguishing Liabilities from Equity” which requires, among other things, that financial instruments that represent a mandatory obligation of the Company to repurchase shares be classified as liabilities and reported at settlement value. When approved, the Company will reclassify such obligations from equity to an accrued liability based upon their respective settlement values. The Company has recorded liabilities of $11.7 million and $5.0 million in accounts payable and accrued expenses in the accompanying consolidated balance sheets as of December 31, 2017 and December 31, 2016 , respectively, related to shares tendered for redemption and approved by the board of directors, but which were not redeemed until the subsequent month. Such amounts have been included in redemption of common shares in the accompanying consolidated statements of equity. Per Share Data Net income (loss) per common share is calculated by dividing the net income (loss) attributable to common stockholders for each period by the weighted average number of common shares outstanding during such period. Net income (loss) per common share on a basic and diluted basis is the same because the Company has no potentially dilutive common shares outstanding. Immaterial Restatement During the performance of the Company’s year end procedures on the consolidated financial statements included in this Annual Report on Form 10-K for the year ended December 31, 2017, management identified certain immaterial incorrect allocations of net income between the Company’s stockholders and noncontrolling interests pertaining to preferred equity securities of the Brindleyplace JV for the years ended December 31, 2016 and 2015. As a result, the prior period Consolidated Financial Statements and the Notes to the Consolidated Financial Statements included in this Annual Report on Form 10-K have been restated from the amounts previously reported to reflect the appropriate allocation of net income related to the Brindleyplace JV. The tables below show the effect of the immaterial restatement (in thousands). December 31, 2016 As Reported Adjustment As Corrected Consolidated Balance Sheets Accumulated distributions in excess of earnings $ (843,900 ) $ 22,400 $ (821,500 ) Total stockholders’ equity $ 1,463,634 $ 22,400 $ 1,486,034 Noncontrolling interests $ 44,601 $ (22,400 ) $ 22,201 2016 2015 As Reported Adjustment As Corrected As Reported Adjustment As Corrected Consolidated Statements of Operations and Comprehensive Income (Loss) Net (income) loss attributable to noncontrolling interests $ (6,177 ) $ 3,614 $ (2,563 ) $ (5,677 ) $ 3,396 $ (2,281 ) Net income (loss) attributable to common stockholders $ 151,050 $ 3,614 $ 154,664 $ (10,631 ) $ 3,396 $ (7,235 ) Basic and diluted income (loss) per common share $ 0.55 $ 0.01 $ 0.56 $ (0.04 ) $ 0.01 $ (0.03 ) Net comprehensive (income) loss attributable to noncontrolling interests $ (2,363 ) $ 3,614 $ 1,251 $ (4,488 ) $ 3,396 $ (1,092 ) Net comprehensive income (loss) attributable to common stockholders $ 114,217 $ 3,614 $ 117,831 $ (49,958 ) $ 3,396 $ (46,562 ) Consolidated Statements of Equity Accumulated Distributions in excess of earnings (As Reported) Adjustment Accumulated Distributions in excess of earnings (As Corrected) Total Stockholders’ Equity (As Reported) Adjustment Total Stockholders’ Equity (As Corrected) Non- controlling Interests (As Reported) Adjustment Non- controlling Interests (As Corrected) Balance as of January 1, 2015 $ (627,203 ) $ 15,390 $ (611,813 ) $ 1,689,388 $ 15,390 $ 1,704,778 $ 46,709 $ (15,390 ) $ 31,319 Net income (loss) $ (10,631 ) $ 3,396 $ (7,235 ) $ (10,631 ) $ 3,396 $ (7,235 ) $ 5,677 $ (3,396 ) $ 2,281 Balance as of December 31, 2015 $ (815,127 ) $ 18,786 $ (796,341 ) $ 1,498,795 $ 18,786 $ 1,517,581 $ 47,929 $ (18,786 ) $ 29,143 Net income (loss) $ 151,050 $ 3,614 $ 154,664 $ 151,050 $ 3,614 $ 154,664 $ 6,177 $ (3,614 ) $ 2,563 Balance as of December 31, 2016 $ (843,900 ) $ 22,400 $ (821,500 ) $ 1,463,634 $ 22,400 $ 1,486,034 $ 44,601 $ (22,400 ) $ 22,201 Recent Accounting Pronouncements In May 2014, the FASB, issued ASU 2014-09 to provide guidance on recognizing revenue from contracts with customers (“ASC 606”). This ASU’s core objective is for an entity to recognize revenue based on the consideration it expects to receive in exchange for goods or services. The amendments also replace prior guidance regarding the recognition of revenue from sales of real estate, except for revenue from sales that are part of a sale-leaseback transaction. Subsequent to ASU 2014-09, the FASB has issued multiple ASUs clarifying multiple aspects of the new revenue recognition standard, which include the deferral of the effective date by one year, and additional guidance for partial sales of non-financial assets. These amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with retrospective or modified retrospective adoption. Expanded quantitative and qualitative disclosures regarding revenue recognition will be required for contracts that are subject to this pronouncement. Rental income from leasing arrangements is specifically excluded from ASU 2014-09, and will be evaluated by the Company in its adoption of the lease accounting standard, ASU 2016-02 (described below). The Company has adopted ASC 606 using the modified retrospective approach effective January 1, 2018. The Company has identified its revenue streams and finalized its evaluation of the impact on our consolidated financial statements and internal accounting processes and determined that accounting for contracts for the sale of real estate will be the primary customer contracts under the scope of ASC 606. The Sale & Purchase Agreement for the sale of the Brindleyplace Project in February 2017 contained certain rent adjustments that the Company has determined do not constitute a separate performance obligation from the performance obligation of title transfer of the Brindleyplace Project. As such, the Company has performed an analysis of the estimated consideration related to the rent adjustments and expects to recognize the cumulative effect by increasing beginning retained earnings by approximately $2.3 million upon adoption in January 2018. In addition, the Company has evaluated controls around the implementation of this ASU and have concluded there will be no significant impact on our control structure. In February 2016, the FASB issued ASU 2016-02 which will require companies that lease assets to recognize on the balance sheet the right-of-use assets and related lease liabilities. The accounting by companies that own the assets leased by the lessee (the lessor) will remain largely unchanged from current GAAP. The new standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The guidance is effective for public entities for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. In January 2018, the FASB issued an exposure draft (“2018 Exposure Draft”) which, if adopted as written, would allow 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. The 2018 Exposure Draft also indicates that companies may be permitted to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption in lieu of the modified retrospective approach and provides other optional practical expedients. The Company is in the process of evaluating the impact that the adoption of ASU 2016-02 will have on the Company’s consolidated financial statements relating to its lessor leases and other lessee leases, if any. Within our lessor leases, we are entitled to receive tenant reimbursements for operating expenses such as real estate taxes, insurance and common area maintenance. Currently upon adoption of this ASU, CAM reimbursement revenue will be accounted for in accordance with Topic 606. The Company has currently identified certain areas the Company believes may be impacted by the adoption of ASU 2016-02, which include: • The bifurcation of lease arrangements in which contractual amounts due are on a gross basis and the amount under contract is not allocated between rental and expense reimbursements, such as real estate taxes and insurance. This process would be based on the underlying fair values of these items. • The Company has ground lease agreements in which the Company is the lessee for land underneath New City and the properties in the Poland Logistics Portfolio that the Company currently accounts for as operating leases. Upon adoption of ASU 2016-02, the Company will record any rights and obligations under these leases as an asset and liability at fair value in the Company’s consolidated balance sheets. • Determination of costs to be capitalized associated with leases. ASU 2016-02 will limit the capitalization associated with certain costs to costs that are a direct result of obtaining a lease. In June 2016, the FASB issued ASU 2016-13 that requires the impairment of financial instruments to be based on expected credit losses. The new standard requires a modified retrospective transition approach using a cumulative effect adjustment to retained earnings in the first reporting period for with the guidance is effective. These amendments are effective for fiscal years and interim periods within those years, beginning after December 15, 2019 and early adoption is permitted for years and interim periods within those years beginning after December 15, 2018. The Company is currently assessing the impact the adoption of this guidance will have on its financial statements. In January 2017, the FASB issued ASU 2017-01 to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in the ASU are effective for public entities for annual and interim periods in fiscal years beginning after December 15, 2017 and early adoption is permitted with prospective application. The Company adopted ASU 2017-01 as of January 1, 2018. In February 2017, the FASB issued ASU No. 2017-05 to clarify that a financial asset is within the scope of Subtopic 610-20 if it meets the definition, as amended, of an in substance nonfinancial asset. If substantially all of the fair value of assets that are promised to a counterparty in a contract is concentrated in nonfinancial assets, then all of the financial assets promised to the counterparty are in substance nonfinancial assets within the scope of Subtopic 610-20, including a parent transferring control of a nonfinancial asset through a transfer of ownership interests of a consolidated subsidiary. The provisions of ASU No. 2017-05 are effective for the Company as of January 1, 2018. To date, the Company has not had any sales of in-substance nonfinancial assets.

Derivative Instruments and Hedges, Assets [Abstract]
DERIVATIVE INSTRUMENTS	DERIVATIVE INSTRUMENTS The Company has entered into several interest rate swap contracts and interest rate cap agreements as economic hedges against the variability of future interest rates on its variable interest rate borrowings. The Company’s interest rate swaps effectively fixed the interest rates on each of the loans to which they relate and the interest rate cap contracts have effectively limited the interest rate on the loans to which they relate. The Company has not designated any of these derivatives as hedges for accounting purposes. See Note 11 — Fair Value Measurements for additional information regarding the fair value of our interest rate contracts. The Company has also entered into foreign currency forward contracts as economic hedges against the variability of foreign exchange rates on future international property sales. These forward contracts economically fix the currency exchange rate on the investment to which they relate. The Company did not designate any of these contracts as fair value or cash flow hedges for accounting purposes. See Note 11 — Fair Value Measurements for additional information regarding the fair value of our foreign currency forwards. In June 2017, the Company entered into an €80.0 million foreign currency forward contract with an effective date of June 27, 2017 and a trade date of July 10, 2017, in connection with the sale of the Mercedes Benz Bank from which the Company received proceeds in Euros.

In June 2016, the borrower repaid the outstanding principal balance of the loan upon the sale of the property. See Note 1 — Organization for additional information concerning the 1377 development and the mezzanine loan. The WaterWall Place JV In December 2011, a wholly-owned subsidiary of the Operating Partnership entered into a Limited Partnership Agreement with an affiliate of Hines for the formation of the WaterWall Place JV, for the purpose of developing a residential/living project in Houston, Texas. Hines serves as the initial general partner and as the development partner and the subsidiary of the Operating Partnership is the initial limited partner. The Company has a 93% interest in this joint venture. An affiliate of Hines owns the remaining 7% interest in this joint venture. The Aviva Coral Gables JV In July 2012, a wholly-owned subsidiary of the Operating Partnership entered into a Limited Partnership Agreement with an affiliate of Hines for the formation of Hines Ponce & Bird Holdings LP, a Delaware limited liability company, for the purpose of developing a residential/living project in Miami, Florida. Hines served as the initial general partner and as the development partner and the subsidiary of the Operating Partnership was the initial limited partner. Hines owned a 17% interest in the joint venture and the Company owned the remaining 83% interest through its subsidiary. As compensation for providing development management services, Hines was paid a fee equal to 4% of the development project costs. In addition, subject to certain return thresholds being achieved, the Aviva Coral Gables JV agreement provided that Hines may receive certain incentive distributions in the event the residential/living project was liquidated. The project was completed in April 2015 . In June 2017 , the Aviva Coral Gables JV sold Aviva Coral Gables. See Note 3 — Investment Property for information regarding the sale. Advisory Agreement Pursuant to the Advisory Agreement, the Company is required to pay the following fees and expense reimbursements: Acquisition Fee – Prior to April 2012, the Advisor received an acquisition fee equal to 2.0% of (i) the purchase price of each real estate investment the Company acquired or originated, including any debt attributable to such investments or the principal amounts of any loans originated directly by the Company and (ii) with respect to indirect investments through another entity, such entity’s pro rata share of the gross asset value of all real estate investments held by such entity. In March 2012, the Advisory Agreement was amended to increase the acquisition fee to 2.25% of these amounts. Effective as of April 1, 2015, the Advisory Agreement was further amended in order to reduce the acquisition fee paid to the Advisor from 2.25% to 0.50% of these amounts. Asset Management Fee – The Advisor receives an asset management fee equal to 0.125% per month of the net equity capital invested by the Company in real estate investments as of the end of each month. During the years ended December 31, 2017 , 2016 and 2015 , the Company incurred asset management fees of $37.9 million , $36.8 million and $35.7 million , respectively. Disposition Fee – The Advisor or its affiliates also will be paid a disposition fee of 1.0% of the sales price of any real estate investments sold or 1.0% of the Company’s pro rata share of the sales price with respect to the Company’s indirect investments. The Company’s disposition fees related to the sales of wholly-owned properties are included in the Gain (loss) on sale of real estate investments in the Consolidated Statement of Operations and Comprehensive Income (loss). The disposition fee on the sale of 1377 in 2016 is included in Other Income (loss) on the Consolidated Statement of Operations and Comprehensive Income (loss), as the sale was made through the Company’s equity method investment. Special OP Units – Hines Global REIT Associates Limited Partnership, an affiliate of Hines, owns the special units of the Operating Partnership (“Special OP Units”), which entitle them to receive distributions in an amount equal to 15% of distributions, including from sales of real estate investments, refinancings and other sources, but only after the Company’s stockholders have received, or are deemed to have received, in the aggregate, cumulative distributions equal to their invested capital plus an 8.0% cumulative, non-compounded annual pre-tax return on such invested capital. At the sole discretion of the Advisor, the acquisition fees, asset management fees, debt financing fees and disposition fees are payable, in whole or in part, in cash or units of the Operating Partnership (“OP Units”). For the purposes of the payment of these fees, each OP Unit will be valued at the per-share offering price of the Company’s common stock in its most recent public offering less selling commissions and dealer manager fees. Upon the Advisor’s request, each OP unit can be repurchased for cash or can be converted into one share of the Company’s common stock. The decision to redeem each OP unit for cash or shares is at the Company’s option except in certain circumstances such as the Company’s decision to list its shares on a national securities exchange, a liquidation event or upon termination or nonrenewal of the Advisory Agreement for any reason other than by the Advisor. The Company will recognize the expense related to these OP Units as the related service is performed, as each OP Unit will be fully vested upon issuance. The Company reimburses the Advisor for all expenses paid or incurred by the Advisor in connection with the services provided to the Company, subject to the limitation that the Company will not reimburse the Advisor for any amount by which its operating expenses (including the asset management fee) at the end of the four preceding fiscal quarters exceeds the greater of: (A) 2% of its average invested assets, or (B) 25% of its net income determined without reduction for any additions to reserves for depreciation, bad debts or other similar non-cash reserves and excluding any gain from the sale of the Company’s assets for that period. Notwithstanding the above, the Company may reimburse the Advisor for expenses in excess of this limitation if a majority of the independent directors determines that such excess expenses are justified. The Company reimburses the Advisor for all issuer costs incurred by the Advisor on the Company’s behalf related to the Company’s distribution reinvestment plan offering and the Company’s prior public filings. Property Management and Leasing Agreements The Company pays Hines fees for the management and leasing of some of its properties. Property management fees are equal to a market-based percentage of the gross revenues of the properties managed by Hines or the amount of property management fees recoverable from tenants of the properties managed by Hines under their leases. In addition, if Hines provides leasing services with respect to a property, the Company will pay Hines leasing fees which are usual and customary for that type of property in that geographic area. The Company generally will be required to reimburse Hines for certain operating costs incurred in providing property management and leasing services pursuant to the property management and leasing agreements. Included in this reimbursement of operating costs will be the cost of personnel and overhead expenses related to such personnel located at the property as well as off-site personnel located in Hines’ headquarters and regional offices, to the extent the same relate to or support the performance of Hines’ duties under the agreement. Hines may perform construction management services for the Company for both re-development activities and tenant construction. These fees are considered incremental to the construction effort and will be capitalized to the associated real estate project as incurred. Costs related to tenant construction will be depreciated over the estimated useful life. Costs related to redevelopment activities will be depreciated over the estimated useful life of the associated project. Leasing activities will generally be performed by Hines on the Company’s behalf. Leasing fees will be capitalized and amortized over the life of the related lease. Generally, as compensation for providing development management services, Hines will be paid a fee equal to 3% of the development project costs and as compensation for providing construction management services, an affiliate of Hines also will be paid a contractor’s fee of 5% of the total construction costs of the project.

Noncontrolling Interest [Abstract]
NONCONTROLLING INTERESTS	NONCONTROLLING INTERESTS The Brindleyplace JV issued Convertible Preferred Equity Certificates (“CPEC”) to Moorfield as a result of their contribution to the Brindleyplace JV. Each CPEC was convertible into one capital share of the Brindleyplace JV at any time. The Brindleyplace JV had the option to have the CPECs redeemed at any time prior to the earlier of the liquidation of the Brindleyplace Project or their expiration on July 7, 2059 .

Fair Value Measurements

Fair Value Measurements	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets and inputs other than quoted prices observable for the asset or liability, such as interest rates and yield curves observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In instances in which the inputs used to measure fair value may fall into different levels of the fair value hierarchy, the level in the fair value hierarchy within which the fair value measurement in its entirety has been determined is based on the lowest level input significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. Financial Instruments Measured on a Recurring Basis As described in Note 7 – Derivative Instruments, the Company entered into several interest rate contracts as economic hedges against the variability of future interest rates on its variable interest rate borrowings. The valuation of these derivative instruments is determined based on assumptions that management believes market participants would use in pricing, using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate contracts have been determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. Although the Company has determined the majority of the inputs used to value its interest rate contracts fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties, Commonwealth Bank of Australia, Crédit Agricole, SMBC Capital Markets, ING Capital Markets, and the Australia and New Zealand Banking Group Limited. In adjusting the fair values of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds and guarantees. However, as of December 31, 2017 and 2016 , the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuations of its derivatives. As a result, the Company has determined its derivative valuations are classified in Level 2 of the fair value hierarchy. Additionally, as described in Note 7 — Derivative Instruments, the Company has entered into foreign currency forward contracts as economic hedges against the variability of foreign exchange rates. The valuation of these forward contracts is determined based on assumptions that management believes market participants would use in pricing, using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including currency exchange rate curves and implied volatilities. The Company has determined its foreign currency forward contracts valuations are classified in Level 2 of the fair value hierarchy, as they are based on observable inputs but are not traded in active markets. Financial Instruments Fair Value Disclosures As of December 31, 2017 , the Company estimated that the fair value of its notes payable, which had a book value (excluding any unamortized discount or premium and deferred financing costs) of $1.8 billion , was $1.8 billion . As of December 31, 2016 , the Company estimated that the fair value of its notes payable, which had a book value (excluding any unamortized discount or premium) of $2.2 billion , was $2.2 billion . Management has utilized available market information, such as interest rate and spread assumptions of notes payable with similar terms and remaining maturities, to estimate the amounts required to be disclosed. Although the Company has determined the majority of the inputs used to value its notes payable fall within Level 2 of the fair value hierarchy, the credit quality adjustments associated with its fair value of notes payable utilize Level 3 inputs. However, as of December 31, 2017 and 2016 , the Company has assessed the significance of the impact of the credit quality adjustments on the overall valuations of its fair market value of notes payable and has determined that they are not significant. As a result, the Company has determined these financial instruments utilize Level 2 inputs. Since such amounts are estimates that are based on limited available market information for similar transactions, there can be no assurance that the disclosed values could be realized. As of December 31, 2016 , the Company estimated that the book values of its real estate loans receivable approximated their fair values. Management has utilized available market information, such as interest rate and spread assumptions of loans receivable with similar terms and remaining maturities, to estimate the amounts required to be disclosed. Although the Company has determined the majority of the inputs used to value its real estate notes receivable fall within Level 2 of the fair value hierarchy, the credit quality adjustments associated with its fair value of real estate notes receivable utilize Level 3 inputs. However, as of December 31, 2016 , the Company has assessed the significance of the impact of the credit quality adjustments on the overall valuations of its fair market value of real estate notes receivable and has determined that they are not significant. As a result, the Company has determined these financial instruments utilize Level 2 inputs. Since such amounts are estimates that are based on limited available market information for similar transactions, there can be no assurance that the disclosed values could be realized. As of December 31, 2017 , the Company had no outstanding real estate loans receivable. Other financial instruments not measured at fair value on a recurring basis include cash and cash equivalents, restricted cash, tenant and other receivables, accounts payable and accrued expenses, other liabilities, due to affiliates and distributions payable. The carrying value of these items reasonably approximates their fair value based on their highly-liquid nature and/or short-term maturities. Due to the short-term nature of these instruments, Level 1 inputs are utilized to estimate the fair value of the cash and cash equivalents and restricted cash and Level 2 inputs are utilized to estimate the fair value of the remaining financial instruments. Financial Instruments Measured on a Nonrecurring Basis Certain long-lived assets are measured at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments (i.e., impairments) in certain circumstances. The fair value methodologies used to measure long-lived assets are described in Note 2 — Summary of Significant Accounting Policies — Investment Property and Lease Intangibles. The inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy as discussed below. Impairment of Investment Property Investment properties are reviewed for impairment at each reporting period if events or changes in circumstances indicate that the carrying amount may not be recoverable. For the year ended December 31, 2017 , the Company determined that one of its properties was impaired as a result of deteriorating market conditions. The changes in assumptions resulted in the net book value of the assets exceeding the projected undiscounted cash flows for the property. As a result, the assets were written down to fair value. The following table summarizes activity for the Company’s assets measured at fair value, on a non-recurring basis, for the years ended December 31, 2017 , 2016 and 2015 (in thousands). Basis of Fair Value Measurements During the year ended Description Fair Value of Assets Quoted Prices (Level 1) Significant (Level 2) Significant (Level 3) Impairment Loss December 31, 2017 Investment property $ 25,700 $ — $ — $ 25,700 $ 7,124 December 31, 2016 Investment property $ — $ — $ — $ — $ — December 31, 2015 Investment property $ — $ — $ — $ — $ — The Company’s estimated fair value of the investment property was based on a comparison of recent market activity and discounted cash flow models, which include estimates of property-specific inflows and outflows over a specific holding period. Significant unobservable quantitative inputs used in determining the fair value of the investment property for the period ended December 31, 2017 include: a discount rate of 9.0% ; a capitalization rate of 7.5% ; stabilized occupancy rate of 92.5% ; and a current market rental rate of $28.00 per square foot. These inputs are based on the location, type and nature of each property, current and anticipated market conditions, and management’s knowledge and expertise in real estate.

Segment Reporting [Abstract]
REPORTABLE SEGMENTS	REPORTABLE SEGMENTS The Company’s real estate investments are geographically diversified and management evaluates the operating performance of each at an individual investment level and considers each investment to be an operating segment. The Company has aggregated all of its operating segments into four reportable segments based on the location of the segment and the underlying asset class. Management has aggregated the Company’s investments that are not office properties in “other” based on the geographic location of the investment due to the Company’s ownership of interests in various different types of investments that do not stand alone as their own reportable segment. • Domestic office investments ( 9 investments) • Domestic other investments ( 5 investments) • International office investments ( 9 investments) • International other investments ( 11 investments) The tables below provide additional information related to each of the Company’s segments, geographic location and a reconciliation to the Company’s net income (loss), as applicable. “Corporate-Level Accounts” includes amounts incurred by the corporate-level entities which are not allocated to any of the reportable segments (all amounts are in thousands, except for percentages): Years Ended December 31, 2017 2016 2015 Total Revenue Domestic office investments $ 173,949 $ 177,048 $ 168,962 Domestic other investments 93,748 123,384 119,083 International office investments 92,617 110,308 123,010 International other investments 43,335 67,168 65,818 Total Revenue $ 403,649 $ 477,908 $ 476,873 For the years ended December 31, 2017 , 2016 and 2015 , the Company’s total revenue was attributable to the following countries: Years Ended December 31, 2017 2016 2015 United States 65 % 62 % 60 % United Kingdom 9 % 15 % 17 % Australia 9 % 7 % 8 % Germany 6 % 5 % 4 % Poland 6 % 5 % 5 % Russia 3 % 3 % 3 % France 2 % 3 % 3 % For the years ended December 31, 2017 , 2016 and 2015 , the Company’s property revenues in excess of expenses by segment was as follows: Years Ended December 31, 2017 2016 2015 Property revenues in excess of expenses (1) Domestic office investments $ 108,638 $ 113,763 $ 107,116 Domestic other investments 59,218 78,729 76,835 International office investments 57,966 85,986 97,644 International other investments 31,988 47,181 45,608 Total property revenues in excess of expenses $ 257,810 $ 325,659 $ 327,203 (1) Revenues less property operating expenses, real property taxes and property management fees.

Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The Company’s consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of the consolidated financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities and contingencies as of the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. The Company evaluates its assumptions and estimates on an ongoing basis. The Company bases its estimates on historical experience and on various other assumptions that the Company believes to be reasonable under the circumstances. Additionally, application of the Company’s accounting policies involves exercising judgments regarding assumptions as to future uncertainties. Actual results may differ from these estimates under different assumptions or conditions.
Basis of Presentation	Basis of Presentation The consolidated financial statements of the Company include the accounts of Hines Global REIT, Inc., the Operating Partnership and its wholly-owned subsidiaries and the joint ventures as well as amounts related to noncontrolling interests. All intercompany balances and transactions have been eliminated in consolidation. The Company evaluates the need to consolidate joint ventures in accordance with GAAP. In accordance with GAAP, the Company will consolidate joint ventures that are determined to be variable interest entities for which it is the primary beneficiary. Further, partially owned real estate joint ventures over which the Company has a controlling financial interest are consolidated in its financial statements. In determining if the Company has a controlling financial interest, it considers factors such as ownership interest, authority to make decisions, kick-out rights and substantive participating rights. Management continually analyzes and assesses reconsideration events, including changes in these factors, to determine if the consolidation treatment remains appropriate. Partially owned real estate joint ventures where the Company does not have a controlling financial interest, but has the ability to exercise significant influence, are accounted for using the equity method. The Company’s investments in partially owned real estate joint ventures are reviewed for impairment periodically if events or circumstances change indicating that the carrying amount of its investments may not be recoverable. In such an instance, the Company will record an impairment charge if it determines that a decline in the value of an investment below its fair value is other than temporary. The Company’s analysis will be dependent on a number of factors, including the performance of each investment, current market conditions, and its intent and ability to hold the investment to full recovery. As of December 31, 2017 and 2016 , the Company no longer had any investments in unconsolidated partially owned real estate joint ventures. Based on the Company’s analysis of the facts and circumstances at each reporting period, no impairment was recorded related to its investments in partially owned real estate joint ventures for the years ended December 31, 2017 , 2016 or 2015 .
International Operations	International Operations The British pound (“GBP”) is the functional currency for the Company’s subsidiaries operating in the United Kingdom, the Russian rouble (“RUB”) is the functional currency for the Company’s subsidiaries operating in Russia, the Polish zloty (“PLN”) is the functional currency for the Company’s subsidiaries operating in Poland, the Australian dollar (“AUD”) is the functional currency for the Company’s subsidiaries operating in Australia and the Euro (“EUR”) is the functional currency for the Company’s subsidiaries operating in Germany and France. These subsidiaries have translated their financial statements into U.S. dollars for reporting purposes. Assets and liabilities are translated at the exchange rate in effect as of the balance sheet date while income statement accounts are translated using the average exchange rate for the period and significant nonrecurring transactions using the rate on the transaction date. Gains or losses resulting from translation are included in accumulated other comprehensive income (loss) within stockholders’ equity. Foreign currency transaction gains and losses are recorded in foreign currency gains (losses) on the consolidated statement of operations and result from the effect of changes in exchange rates on transactions denominated in currencies other than a subsidiary’s functional currency, including transactions between consolidated subsidiaries. An exception is made where an intercompany loan or advance is deemed to be of a long-term investment nature, in which instance foreign currency transaction gains or losses are included as currency translation adjustments and are reported in the consolidated statement of equity as accumulated other comprehensive gains or losses.
Investment Property and Lease Intangibles	Investment Property and Lease Intangibles Real estate assets acquired by the Company are stated at fair value at the date of acquisition less accumulated depreciation. Depreciation is computed using the straight-line method. The estimated useful lives for computing depreciation are generally 10 years for furniture and fixtures, 15 - 20 years for electrical and mechanical installations and 40 years for buildings. Major replacements that extend the useful life of the assets are capitalized and maintenance and repair costs are expensed as incurred. Acquisitions of properties are accounted for utilizing the acquisition method and, accordingly, are recorded at the estimated fair values of the assets acquired and liabilities assumed. The results of operations of acquired properties are included in the Company’s results of operations from their respective dates of acquisition. Estimates of fair values are based upon estimates of future cash flows and other valuation techniques that the Company believes are similar to those used by market participants and are used to record the purchase of identifiable assets acquired, such as land, buildings and improvements, equipment and identifiable intangible assets related to in-place leases and liabilities assumed, such as amounts related to acquired out-of-market leases, asset retirement obligations, mortgage notes payable. Values of buildings and improvements are determined on an as if vacant basis. Initial valuations are subject to change until such information is finalized, no later than 12 months from the acquisition date. For prior acquisitions, acquisition-related costs such as transaction costs and acquisition fees paid to the Advisor were expensed as incurred. Beginning in 2018, when Accounting Standards Update (“ASU”) 2017-01 becomes effective, any acquisition-related costs and acquisition fees to any future acquisitions will be capitalized. See Recent Accounting Pronouncements below for more information on ASU 2017-01. The estimated fair value of acquired in-place leases are the costs the Company would have incurred to lease the properties to the occupancy level of the properties at the date of acquisition. Such estimates include the fair value of leasing commissions, legal costs and other direct costs that would be incurred to lease the properties to such occupancy levels. Additionally, the Company evaluates the time period over which such occupancy levels would be achieved. Such evaluation will include an estimate of the net market-based rental revenues and net operating costs (primarily consisting of real estate taxes, insurance and utilities) that would be incurred during the lease-up period. Acquired in-place leases as of the date of acquisition are amortized over the remaining lease terms. Should a tenant terminate its lease, the unamortized portion of the in-place lease value is charged to amortization expense. Acquired out-of-market lease values (including ground leases) are recorded based on the present value (using a discount rate that reflects the risks associated with the lease acquired) of the difference between the contractual amounts paid pursuant to the in-place leases and management’s estimate of fair market value lease rates for the corresponding in-place leases. The capitalized out-of-market lease values are amortized as adjustments to rental revenue (or ground lease expense, as applicable) over the remaining terms of the respective leases, which include periods covered by bargain renewal options. Should a tenant terminate its lease, the unamortized portion of the out-of-market lease value is charged to rental revenue. Management estimates the fair value of assumed mortgage notes payable based upon indications of then-current market pricing for similar types of debt with similar maturities. Assumed mortgage notes payable are initially recorded at their estimated fair value as of the assumption date, and the difference between such estimated fair value and the outstanding principal balance of the note will be amortized over the life of the mortgage note payable.
Impairment of Investment Property	Real estate assets are reviewed for impairment each reporting period if events or changes in circumstances indicate that the carrying amount of the individual property may not be recoverable. In such an event, a comparison will be made of the current and projected operating cash flows and expected proceeds from the eventual disposition of each property on an undiscounted basis to the carrying amount of such property. If the carrying amount exceeds the undiscounted cash flows, it would be written down to the estimated fair value to reflect impairment in the value of the asset. The determination of whether investment property is impaired requires a significant amount of judgment by management and is based on the best information available to management at the time of the evaluation. Impairment of Investment Property Investment properties are reviewed for impairment at each reporting period if events or changes in circumstances indicate that the carrying amount may not be recoverable.
Cash and Cash Equivalents	Cash and Cash Equivalents The Company considers all short-term, highly liquid investments that are readily convertible to cash with an original maturity of three months or less at the time of purchase to be cash equivalents.
Restricted Cash	Restricted Cash The Company has restricted cash primarily related to certain escrow accounts required by several of the Company’s mortgage agreements.
Concentration of Credit Risk	Concentration of Credit Risk As of December 31, 2017 , the Company had cash and cash equivalents and restricted cash deposited in certain financial institutions in excess of federally insured levels. Management regularly monitors the financial stability of these financial institutions in an effort to manage the Company’s exposure to any significant credit risk in cash and cash equivalents or restricted cash.
Tenant and Other Receivables	Tenant and Other Receivables Receivable balances consist primarily of base rents, tenant reimbursements and receivables attributable to straight-line rent. An allowance for the uncollectible portion of tenant and other receivables is determined based upon an analysis of 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.
Deferred Leasing and Financing Costs	Deferred Financing Costs Deferred financing costs consist of direct costs incurred in obtaining debt financing (see Note 6 - Debt Financing). These fees are presented as a reduction to the related debt liability for permanent mortgages and presented as an asset for revolving credit arrangements. In total, deferred financing costs (net of amortization) were $6.5 million and $10.8 million as of December 31, 2017 and 2016 . These costs are amortized into interest expense on a straight-line basis, which approximates the effective interest method, over the terms of the obligations. Deferred Leasing Costs Direct leasing costs, primarily consisting of third-party leasing commissions, tenant inducements and legal costs are capitalized and amortized over the life of the related lease. Tenant inducement amortization is recorded as an offset to rental revenue and the amortization of other direct leasing costs is recorded in amortization expense.
Real Estate Loans Receivable	Real Estate Loans Receivable Real estate loans receivable are shown at cost, net of any applicable allowance for uncollectibility and net of deferred loan origination fees. The Company defers certain loan origination fees and amortizes them as an adjustment of yield over the term of the related real estate loan receivable. The related amortization of the deferred loan origination fees are recorded in other revenue in the accompanying consolidated statement of operations and comprehensive income (loss). An allowance for the uncollectible portion of the real estate loans receivable is determined based upon an analysis of the economic conditions in the area in which the property is located and credit quality indicators which include: borrower’s payment history, the financial condition of the borrower, and business conditions in the industry in which the borrower operates. Additionally, a real estate loan receivable is considered to be impaired, when based upon current events, it is probable that we will be unable to collect all amounts due according to the existing contractual terms. If a real estate loan receivable is considered to be impaired, the amount of loss is calculated by comparing the recorded investment to the value determined by discounting the expected future cash flows at its effective interest rate or to the value of the underlying collateral if the real estate loan receivable is collateral dependent. Evaluating real estate loans receivable for potential impairment can require management to exercise significant judgment.
Revenue Recognition	Revenue Recognition Rental payments are generally paid by the tenants prior to the beginning of each month. As of December 31, 2017 and December 31, 2016 , respectively, the Company recorded liabilities of $16.7 million and $27.3 million related to prepaid rental payments which were included in other liabilities in the accompanying consolidated balance sheets. The Company recognizes rental revenue on a straight-line basis over the life of the lease including rent holidays, if any. Straight-line rent receivable was $53.9 million and $89.4 million as of December 31, 2017 and December 31, 2016 , respectively. Straight-line rent receivable consists of the difference between the tenants’ rents calculated on a straight-line basis from the date of acquisition or lease commencement over the remaining terms of the related leases and the tenants’ actual rents due under the lease agreements and is included in tenant and other receivables in the accompanying consolidated balance sheets. Revenues associated with operating expense recoveries are recognized in the period in which the expenses are incurred based upon the tenant lease provisions. Revenues relating to lease termination fees are recognized on a straight-line basis amortized from the time that a tenant’s right to occupy the leased space is modified through the end of the revised lease term. Other revenues consist primarily of parking revenue, tenant reimbursements and interest on loans receivable. Parking revenue represents amounts generated from contractual and transient parking and is recognized in accordance with contractual terms or as services are rendered. Other revenues relating to tenant reimbursements are recognized in the period that the expense is incurred.
Income Taxes	Income Taxes The Company has elected to be treated as a REIT under the Internal Revenue Code of 1986, as amended (the “Code”). The Company’s management believes that it operates in such a manner as to qualify for treatment as a REIT and intends to operate in the foreseeable future in such a manner so that it will remain qualified as a REIT for federal income tax purposes. Accordingly, no provision has been made for U.S. federal income taxes for the years ended December 31, 2017 , 2016 and 2015 in the accompanying consolidated financial statements. In 2017 , 2016 and 2015 , income tax expense recorded by the Company was primarily comprised of foreign income taxes related to the operation its international properties. The Company does not believe it has any uncertain tax positions or unrecognized tax benefits requiring disclosure. On December 22, 2017, the U.S. government enacted the Tax Cuts and Jobs Act. The Tax Cuts and Jobs Act makes broad and complex changes to the Internal Revenue Code including, but not limited to, (1) reducing the top U.S. federal corporate income tax rate from 35% to 21%, (2) establishing a 20% deduction for ordinary REIT dividends (other than any portion that is a capital gain dividend or qualified dividend income, subject to complex limitations), (3) limiting the deductibility of business interest expenses, (4) allowing full expensing of certain qualifying property, (5) eliminating the corporate Alternative Minimum Tax (“AMT”) and changing how existing AMT credits can be realized, (6) limiting current net operating loss deductions and providing an indefinite carryforward and (7) limiting the deductibility of certain executive compensation. The Company’s evaluation of deferred taxes and the associated valuation allowance includes an estimate of the impact of the Tax Cuts and Jobs Act and was based on the best information available to the Company at the time.
Redemption of Common Stock	Redemption of Common Stock The Company complies with Financial Accounting Standards Board (“FASB”) ASC 480 “Distinguishing Liabilities from Equity” which requires, among other things, that financial instruments that represent a mandatory obligation of the Company to repurchase shares be classified as liabilities and reported at settlement value. When approved, the Company will reclassify such obligations from equity to an accrued liability based upon their respective settlement values.
Per Share Data	Per Share Data Net income (loss) per common share is calculated by dividing the net income (loss) attributable to common stockholders for each period by the weighted average number of common shares outstanding during such period. Net income (loss) per common share on a basic and diluted basis is the same because the Company has no potentially dilutive common shares outstanding.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In May 2014, the FASB, issued ASU 2014-09 to provide guidance on recognizing revenue from contracts with customers (“ASC 606”). This ASU’s core objective is for an entity to recognize revenue based on the consideration it expects to receive in exchange for goods or services. The amendments also replace prior guidance regarding the recognition of revenue from sales of real estate, except for revenue from sales that are part of a sale-leaseback transaction. Subsequent to ASU 2014-09, the FASB has issued multiple ASUs clarifying multiple aspects of the new revenue recognition standard, which include the deferral of the effective date by one year, and additional guidance for partial sales of non-financial assets. These amendments are effective for fiscal years, and interim periods within those years, beginning after December 15, 2017, with retrospective or modified retrospective adoption. Expanded quantitative and qualitative disclosures regarding revenue recognition will be required for contracts that are subject to this pronouncement. Rental income from leasing arrangements is specifically excluded from ASU 2014-09, and will be evaluated by the Company in its adoption of the lease accounting standard, ASU 2016-02 (described below). The Company has adopted ASC 606 using the modified retrospective approach effective January 1, 2018. The Company has identified its revenue streams and finalized its evaluation of the impact on our consolidated financial statements and internal accounting processes and determined that accounting for contracts for the sale of real estate will be the primary customer contracts under the scope of ASC 606. The Sale & Purchase Agreement for the sale of the Brindleyplace Project in February 2017 contained certain rent adjustments that the Company has determined do not constitute a separate performance obligation from the performance obligation of title transfer of the Brindleyplace Project. As such, the Company has performed an analysis of the estimated consideration related to the rent adjustments and expects to recognize the cumulative effect by increasing beginning retained earnings by approximately $2.3 million upon adoption in January 2018. In addition, the Company has evaluated controls around the implementation of this ASU and have concluded there will be no significant impact on our control structure. In February 2016, the FASB issued ASU 2016-02 which will require companies that lease assets to recognize on the balance sheet the right-of-use assets and related lease liabilities. The accounting by companies that own the assets leased by the lessee (the lessor) will remain largely unchanged from current GAAP. The new standard requires a modified retrospective transition approach for all leases existing at, or entered into after, the date of initial application, with an option to use certain transition relief. The guidance is effective for public entities for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years. Early adoption is permitted. In January 2018, the FASB issued an exposure draft (“2018 Exposure Draft”) which, if adopted as written, would allow 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. The 2018 Exposure Draft also indicates that companies may be permitted to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption in lieu of the modified retrospective approach and provides other optional practical expedients. The Company is in the process of evaluating the impact that the adoption of ASU 2016-02 will have on the Company’s consolidated financial statements relating to its lessor leases and other lessee leases, if any. Within our lessor leases, we are entitled to receive tenant reimbursements for operating expenses such as real estate taxes, insurance and common area maintenance. Currently upon adoption of this ASU, CAM reimbursement revenue will be accounted for in accordance with Topic 606. The Company has currently identified certain areas the Company believes may be impacted by the adoption of ASU 2016-02, which include: • The bifurcation of lease arrangements in which contractual amounts due are on a gross basis and the amount under contract is not allocated between rental and expense reimbursements, such as real estate taxes and insurance. This process would be based on the underlying fair values of these items. • The Company has ground lease agreements in which the Company is the lessee for land underneath New City and the properties in the Poland Logistics Portfolio that the Company currently accounts for as operating leases. Upon adoption of ASU 2016-02, the Company will record any rights and obligations under these leases as an asset and liability at fair value in the Company’s consolidated balance sheets. • Determination of costs to be capitalized associated with leases. ASU 2016-02 will limit the capitalization associated with certain costs to costs that are a direct result of obtaining a lease. In June 2016, the FASB issued ASU 2016-13 that requires the impairment of financial instruments to be based on expected credit losses. The new standard requires a modified retrospective transition approach using a cumulative effect adjustment to retained earnings in the first reporting period for with the guidance is effective. These amendments are effective for fiscal years and interim periods within those years, beginning after December 15, 2019 and early adoption is permitted for years and interim periods within those years beginning after December 15, 2018. The Company is currently assessing the impact the adoption of this guidance will have on its financial statements. In January 2017, the FASB issued ASU 2017-01 to clarify the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The amendments in the ASU are effective for public entities for annual and interim periods in fiscal years beginning after December 15, 2017 and early adoption is permitted with prospective application. The Company adopted ASU 2017-01 as of January 1, 2018. In February 2017, the FASB issued ASU No. 2017-05 to clarify that a financial asset is within the scope of Subtopic 610-20 if it meets the definition, as amended, of an in substance nonfinancial asset. If substantially all of the fair value of assets that are promised to a counterparty in a contract is concentrated in nonfinancial assets, then all of the financial assets promised to the counterparty are in substance nonfinancial assets within the scope of Subtopic 610-20, including a parent transferring control of a nonfinancial asset through a transfer of ownership interests of a consolidated subsidiary. The provisions of ASU No. 2017-05 are effective for the Company as of January 1, 2018. To date, the Company has not had any sales of in-substance nonfinancial assets.
Derivative Instruments	The Company has entered into several interest rate swap contracts and interest rate cap agreements as economic hedges against the variability of future interest rates on its variable interest rate borrowings. The Company’s interest rate swaps effectively fixed the interest rates on each of the loans to which they relate and the interest rate cap contracts have effectively limited the interest rate on the loans to which they relate. The Company has not designated any of these derivatives as hedges for accounting purposes. See Note 11 — Fair Value Measurements for additional information regarding the fair value of our interest rate contracts. The Company has also entered into foreign currency forward contracts as economic hedges against the variability of foreign exchange rates on future international property sales. These forward contracts economically fix the currency exchange rate on the investment to which they relate. The Company did not designate any of these contracts as fair value or cash flow hedges for accounting purposes.
Fees and Expense Reimbursements	Special OP Units – Hines Global REIT Associates Limited Partnership, an affiliate of Hines, owns the special units of the Operating Partnership (“Special OP Units”), which entitle them to receive distributions in an amount equal to 15% of distributions, including from sales of real estate investments, refinancings and other sources, but only after the Company’s stockholders have received, or are deemed to have received, in the aggregate, cumulative distributions equal to their invested capital plus an 8.0% cumulative, non-compounded annual pre-tax return on such invested capital. At the sole discretion of the Advisor, the acquisition fees, asset management fees, debt financing fees and disposition fees are payable, in whole or in part, in cash or units of the Operating Partnership (“OP Units”). For the purposes of the payment of these fees, each OP Unit will be valued at the per-share offering price of the Company’s common stock in its most recent public offering less selling commissions and dealer manager fees. Upon the Advisor’s request, each OP unit can be repurchased for cash or can be converted into one share of the Company’s common stock. The decision to redeem each OP unit for cash or shares is at the Company’s option except in certain circumstances such as the Company’s decision to list its shares on a national securities exchange, a liquidation event or upon termination or nonrenewal of the Advisory Agreement for any reason other than by the Advisor. The Company will recognize the expense related to these OP Units as the related service is performed, as each OP Unit will be fully vested upon issuance. The Company reimburses the Advisor for all expenses paid or incurred by the Advisor in connection with the services provided to the Company, subject to the limitation that the Company will not reimburse the Advisor for any amount by which its operating expenses (including the asset management fee) at the end of the four preceding fiscal quarters exceeds the greater of: (A) 2% of its average invested assets, or (B) 25% of its net income determined without reduction for any additions to reserves for depreciation, bad debts or other similar non-cash reserves and excluding any gain from the sale of the Company’s assets for that period. Notwithstanding the above, the Company may reimburse the Advisor for expenses in excess of this limitation if a majority of the independent directors determines that such excess expenses are justified. Acquisition Fee – Prior to April 2012, the Advisor received an acquisition fee equal to 2.0% of (i) the purchase price of each real estate investment the Company acquired or originated, including any debt attributable to such investments or the principal amounts of any loans originated directly by the Company and (ii) with respect to indirect investments through another entity, such entity’s pro rata share of the gross asset value of all real estate investments held by such entity. In March 2012, the Advisory Agreement was amended to increase the acquisition fee to 2.25% of these amounts. Effective as of April 1, 2015, the Advisory Agreement was further amended in order to reduce the acquisition fee paid to the Advisor from 2.25% to 0.50% of these amounts. Asset Management Fee – The Advisor receives an asset management fee equal to 0.125% per month of the net equity capital invested by the Company in real estate investments as of the end of each month. Disposition Fee – The Advisor or its affiliates also will be paid a disposition fee of 1.0% of the sales price of any real estate investments sold or 1.0% of the Company’s pro rata share of the sales price with respect to the Company’s indirect investments.
Property Management and Leasing Agreements	Property Management and Leasing Agreements The Company pays Hines fees for the management and leasing of some of its properties. Property management fees are equal to a market-based percentage of the gross revenues of the properties managed by Hines or the amount of property management fees recoverable from tenants of the properties managed by Hines under their leases. In addition, if Hines provides leasing services with respect to a property, the Company will pay Hines leasing fees which are usual and customary for that type of property in that geographic area. The Company generally will be required to reimburse Hines for certain operating costs incurred in providing property management and leasing services pursuant to the property management and leasing agreements. Included in this reimbursement of operating costs will be the cost of personnel and overhead expenses related to such personnel located at the property as well as off-site personnel located in Hines’ headquarters and regional offices, to the extent the same relate to or support the performance of Hines’ duties under the agreement. Hines may perform construction management services for the Company for both re-development activities and tenant construction. These fees are considered incremental to the construction effort and will be capitalized to the associated real estate project as incurred. Costs related to tenant construction will be depreciated over the estimated useful life. Costs related to redevelopment activities will be depreciated over the estimated useful life of the associated project. Leasing activities will generally be performed by Hines on the Company’s behalf. Leasing fees will be capitalized and amortized over the life of the related lease.
Fair Value of Financial Instruments	Financial Instruments Measured on a Nonrecurring Basis Certain long-lived assets are measured at fair value on a non-recurring basis. These assets are not measured at fair value on an ongoing basis, but are subject to fair value adjustments (i.e., impairments) in certain circumstances. The fair value methodologies used to measure long-lived assets are described in Note 2 — Summary of Significant Accounting Policies — Investment Property and Lease Intangibles. The inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy as discussed below. Fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities the Company has the ability to access. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets and inputs other than quoted prices observable for the asset or liability, such as interest rates and yield curves observable at commonly quoted intervals. Level 3 inputs are unobservable inputs for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability. In instances in which the inputs used to measure fair value may fall into different levels of the fair value hierarchy, the level in the fair value hierarchy within which the fair value measurement in its entirety has been determined is based on the lowest level input significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. Financial Instruments Measured on a Recurring Basis As described in Note 7 – Derivative Instruments, the Company entered into several interest rate contracts as economic hedges against the variability of future interest rates on its variable interest rate borrowings. The valuation of these derivative instruments is determined based on assumptions that management believes market participants would use in pricing, using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves and implied volatilities. The fair values of interest rate contracts have been determined using the market standard methodology of netting the discounted future fixed cash receipts (or payments) and the discounted expected variable cash payments (or receipts). The variable cash payments (or receipts) are based on an expectation of future interest rates (forward curves) derived from observable market interest rate curves. Although the Company has determined the majority of the inputs used to value its interest rate contracts fall within Level 2 of the fair value hierarchy, the credit valuation adjustments associated with its derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by the Company and its counterparties, Commonwealth Bank of Australia, Crédit Agricole, SMBC Capital Markets, ING Capital Markets, and the Australia and New Zealand Banking Group Limited. In adjusting the fair values of its derivative contracts for the effect of nonperformance risk, the Company has considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds and guarantees. However, as of December 31, 2017 and 2016 , the Company has assessed the significance of the impact of the credit valuation adjustments on the overall valuation of its derivative positions and has determined that the credit valuation adjustments are not significant to the overall valuations of its derivatives. As a result, the Company has determined its derivative valuations are classified in Level 2 of the fair value hierarchy. Additionally, as described in Note 7 — Derivative Instruments, the Company has entered into foreign currency forward contracts as economic hedges against the variability of foreign exchange rates. The valuation of these forward contracts is determined based on assumptions that management believes market participants would use in pricing, using widely accepted valuation techniques, including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including currency exchange rate curves and implied volatilities. The Company has determined its foreign currency forward contracts valuations are classified in Level 2 of the fair value hierarchy, as they are based on observable inputs but are not traded in active markets.
