Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION The accompanying interim unaudited condensed consolidated financial information has been prepared according to the rules and regulations of the United States Securities and Exchange Commission (“SEC”). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted according to such rules and regulations. For further information, refer to the financial statements and footnotes for the year ended December 31, 2018 included in Hines Global REIT, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2018 . In the opinion of management, all adjustments and eliminations, consisting only of normal recurring adjustments, necessary to present fairly and in conformity with GAAP the financial position of Hines Global REIT, Inc. as of June 30, 2019 , the results of operations for the three and six months ended June 30, 2019 and 2018 and cash flows for the six months ended June 30, 2019 and 2018 have been included. The results of operations for such interim periods are not necessarily indicative of the results for the full year. 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. The Company operates in a manner to qualify as a real estate investment trust (“REIT”) for U.S. federal income tax purposes. The 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 (the “Advisory Agreement”). The Company raised the equity capital for its real estate investments through two public offerings from August 5, 2009 through April 11, 2014 , which included primary offering shares as well as shares issued through its distribution reinvestment plan. The Company terminated its offering of primary offering shares in April 2014, but continued to issue shares through its distribution reinvestment plan (the “DRP Offering”) from April 24, 2014 to August 2018 . Collectively, through these public offerings, the Company received gross offering proceeds of approximately $3.1 billion from the sale of 313.3 million shares, which was invested in the Company’s real estate portfolio. In recent years, the Company has concentrated its efforts on actively managing its assets and exploring a variety of strategic opportunities focused on enhancing the composition of its portfolio and its total return potential for its stockholders. On April 23, 2018 , in connection with its review of potential strategic alternatives available to the Company, the Company’s board of directors determined that it is in the best interest of the Company and its stockholders to sell all or substantially all of the Company’s properties and assets and for the Company to liquidate and dissolve pursuant to a Plan of Liquidation and Dissolution (the “Plan of Liquidation”). The principal purpose of the Plan of Liquidation is to provide liquidity to the Company’s stockholders by selling the Company’s assets, paying its debts and distributing the net proceeds from liquidation to the Company’s stockholders. As required by Maryland law and the Company’s charter, the Plan of Liquidation was approved by the affirmative vote of the holders of at least a majority of the shares of the Company’s common stock outstanding and entitled to vote thereon at the Company’s annual meeting of stockholders held on July 17, 2018 . In accordance with Maryland law, the Plan of Liquidation provides the Company’s board of directors with the authority to modify or amend the Plan of Liquidation without further action by the Company’s stockholders to the extent permitted by then-current law and to terminate the Plan of Liquidation for any reason, provided that the board of directors may not terminate the Plan of Liquidation after Articles of Dissolution have been filed with and accepted for record by the State Department of Assessments and Taxation of Maryland. If the sale of all or substantially all of the Company’s assets is completed as expected, the Company expects to make one or more additional liquidating distributions to its stockholders during the period of the liquidation process and to make the final liquidating distribution to its stockholders on or before a date that is within 24 months after stockholder approval of the Plan of Liquidation. There can be no assurances regarding the timing or amounts of any additional liquidating distributions or that the Company will make the final distribution on or before July 17, 2020. In addition, even if the Company sells all of its assets by July 17, 2020, it may determine not to distribute all distributable cash by that date and may establish a reserve to provide for any remaining obligations and to cover its expenses as it completes its wind down and dissolution. Through August 14, 2019 , the Company has paid aggregate return of capital distributions of $4.00 per share to its stockholders, which included $2.83 per share of liquidating distributions pursuant to the Plan of Liquidation. See “Note 5 — Distributions” for additional information regarding these distributions. Because the Plan of Liquidation follows the Company’s initial business plan and given the Company’s board of directors has the authority to modify, amend, or terminate the Plan of Liquidation without further action by the Company’s stockholders, these financial statements have not been prepared on the liquidation basis of accounting. The Company sold its interests in six properties for an aggregate sales price of $1.0 billion during 2017, 20 properties in 2018 for an aggregate sales price of $1.7 billion , and two properties in the first quarter of 2019 for an aggregate sales price of $477.8 million . As of June 30, 2019 , the Company owned interests in 12 real estate investments, consisting of the following types of investments: • Domestic office investments ( 3 investments) • Domestic other investments ( 4 investments) • International office investments ( 4 investments) • International other investments ( 1 investments) As of August 14, 2019 , the Company has $720.6 million of debt scheduled to mature within a year. The Company does not have sufficient cash on hand or other legally binding commitments that can be utilized to repay such debt. In evaluating the Company’s current and projected sources of liquidity to meet the obligations of such debt, the Company has assessed its available options and has determined that its plan is to repay such obligations with proceeds from the sale of assets pursuant to the Plan of Liquidation. To the extent such proceeds are not sufficient, the Company has determined it is probable that it will either meet the covenant requirements necessary to exercise the extension options on its Revolving Credit Facility (as defined in Note 4) or that market-based alternatives to refinance the maturing debt will be available and that these actions will provide the necessary cash flows to repay the maturing debt.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Described below are certain of the Company’s significant accounting policies. The disclosures regarding several of the policies have been condensed or omitted in accordance with interim reporting regulations specified in the instructions for Form 10-Q. Please see the Company’s Annual Report on Form 10-K for the year ended December 31, 2018 for a complete listing of all of its significant accounting policies. Other Assets Other assets included the following (in thousands): June 30, 2019 December 31, 2018 Prepaid expenses $ 2,506 $ 1,770 Deferred tax assets 14,195 12,654 Other 303 341 Other assets $ 17,004 $ 14,765 Revenue Recognition Rental payments are generally paid by the tenants prior to the beginning of each month or quarter to which they relate. As of June 30, 2019 and December 31, 2018 , respectively, the Company recorded liabilities of $11.7 million and $15.5 million related to prepaid rental payments, which were included in other liabilities in the accompanying Condensed 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 $41.6 million and $44.0 million as of June 30, 2019 and December 31, 2018 , 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 Condensed 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. Parking revenue represents amounts generated from contractual and transient parking and is recognized in accordance with contractual terms or as services are rendered. Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02 which requires companies that lease assets to recognize on the balance sheet the right-of-use assets and related lease liabilities (“ASC 842”). The accounting by companies that own the assets leased by the lessee (the lessor) is largely unchanged from previous GAAP. The Company adopted ASC 842 as of January 1, 2019, and is using the modified retrospective approach. No adjustment to opening retained earnings was required. In July 2018, the FASB issued ASU 2018-11, which allows lessors to account for lease and non-lease components by class of underlying assets, as a single lease component if certain criteria are met. Also, the new standard indicates that companies are permitted to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption in lieu of restating prior periods in accordance with ASC 842 and provides other optional practical expedients. Upon adoption, the Company has elected the following practical expedients: • The transition method in which the application date of January 1, 2019 is the beginning of the reporting period that the Company first applied the new guidance. • The practical expedient package which allows an entity not to reassess (1) whether any expired or existing contracts are or contain leases; (2) the lease classification for any expired or existing leases; (3) initial direct costs for any existing leases. • As an accounting policy election, a lessor may choose not to separate the non-lease components, by class of underlying assets, from the lease components and instead account for both types of components as a single component under certain conditions. • As an accounting policy election, a lessee may choose not to separate the non-lease components, by class of underlying assets, from the lease components and instead account for both types of components as a single component. The Company elected to apply the practical expedient for all of its leases to account for the lease and non-lease components as a single, combined operating lease component. The Company completed its evaluation of the impact that the adoption of ASC 842 will have on the Company’s consolidated financial statements relating to its leases from both the lessee and lessor perspective. Based on the Company’s analysis, the Company identified the following changes to result from its adoption of ASC 842: Lessor Accounting • The Company is entitled to receive tenant reimbursements for operating expenses for common area maintenance (“CAM”). Based on guidance in these ASUs, CAM reimbursement revenue is defined as a non-lease component, which would be accounted for in accordance with ASC 606. However, the Company elected to apply the practical expedient for all of its leases to account for the lease and non-lease components as a single, combined operating lease component. • Capitalization of leasing costs is limited to initial direct costs. Initial direct costs have been defined as incremental costs of a lease that would not have been incurred if the lease had not been obtained. Legal costs are no longer capitalized, but expensed as incurred. There is no change in the Company’s accounting for lease inducements and commissions. • The Company’s existing leases continue to be classified as operating leases, however, leases entered into or modified after January 1, 2019 may be classified as either operating or sales-type leases, based on specific classification criteria. The Company believes all of its leases will continue to be classified as operating leases, and all operating leases will continue to have a similar pattern of recognition as under current GAAP. Lessee Accounting • The Company has two ground lease agreements in which the Company is the lessee for land underneath 25 Cabot Square. The Company previously recognized an amount related to these ground leases as part of the allocation of the purchase price of 25 Cabot Square, which was recorded to intangible lease assets, net. The leases have remaining terms of 198 years and 973 years . Upon adoption of ASC 842 on January 1, 2019, the Company reclassified approximately £58.3 million (approximately $74.4 million converted using an exchange rate of $1.28 per GBP on January 1, 2019) from intangible lease assets, net to right-of-use asset in the Company’s Condensed Consolidated Balance Sheets. No lease liability was recorded since the payments required under the lease are immaterial. • The Company has a ground lease agreement in which the Company is the lessee for land underneath New City that is currently accounted for as an operating lease. The lease currently ends in December 2089 and has fixed payments. The rental expense associated with this lease was $0.2 million and $0.2 million for the six months ended June 30, 2019 , and 2018 , respectively. The Company previously recognized an amount related to this ground lease as part of the allocation of the purchase price of New City, which was recorded to intangible lease assets, net. Upon adoption of ASC 842 on January 1, 2019, the Company recorded a right-of-use asset and lease liability of approximately $3.6 million in right-of-use asset, net and other liabilities, respectively, in the Company’s Condensed Consolidated Balance Sheets and reclassified an additional 65.1 million Polish zloty (“PLN”) (approximately $17.3 million converted using an exchange rate of $0.27 per PLN on January 1, 2019) from intangible lease assets, net to right-of-use asset in the Company’s Condensed Consolidated Balance Sheets. The Company’s estimate of the amount of the right-of-use asset and lease liability included assumptions for the discount rate, which is based on the incremental borrowing rate of the lease contract. The incremental borrowing rate is the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a term similar to the lease. Since the term of the New City ground lease is much longer than a typical borrowing, we derived the incremental borrowing rate of 6.4% , as the spread in a current financing quote for the property plus the applicable base rate corresponding to the longest term available in the base rate market. A reconciliation of our lease liabilities on an undiscounted cash flow basis for the ground lease at New City as of June 30, 2019 , for the period from July 1, 2019 through December 31, 2019 and for each of the years ending December 31, 2020 through December 31, 2024 are as follows (in thousands): Lease Payments July 1, 2019 through December 31, 2019 $ — 2020 238 2021 238 2022 238 2023 238 2024 238 Thereafter 15,475 Total $ 16,665 Lease liabilities (included in other liabilities) $ 3,678 Undiscounted excess amount $ 12,987 New Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-13, "Changes to the Disclosure Requirements for Fair Value Measurement." This ASU amends and removes several disclosure requirements including the valuation processes for Level 3 fair value measurements. The ASU also modifies some disclosure requirements and requires additional disclosures for changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements and requires the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The ASU is effective for fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for any eliminated or modified disclosures upon issuance of this ASU. The Company is currently assessing the impact the adoption of this guidance will have on its financial statements.

The amounts reclassified from intangible lease assets included $93.5 million in gross cost, net of $1.8 million of accumulated amortization. See “Note 2 — Summary of Significant Accounting Policies” for more information on the adoption of ASC 842. As of December 31, 2018 , the cost basis and accumulated amortization related to lease intangibles were as follows (in thousands): Lease Intangibles Out-of-Market Lease Assets Out-of-Market Lease Liabilities In-Place Leases Cost $ 404,662 $ 26,072 $ (99,434 ) Less: accumulated amortization (187,581 ) (16,560 ) 43,913 Net $ 217,081 $ 9,512 $ (55,521 ) Amortization expense of in-place leases was $4.0 million and $14.2 million for the three months ended June 30, 2019 and 2018 , respectively. Net amortization of out-of-market leases resulted in increases to rental revenue of $1.1 million and $3.6 million for the three months ended June 30, 2019 and 2018 , respectively. Amortization expense of in-place leases was $8.5 million and $32.5 million for the six months ended June 30, 2019 and 2018 , respectively. Net amortization of out-of-market leases resulted in increases to rental revenue of $2.1 million and $5.8 million for the six months ended June 30, 2019 and 2018 , respectively. Anticipated amortization of in-place leases and out-of-market leases, net, for the period from July 1, 2019 through December 31, 2019 and for each of the years ending December 31, 2020 through December 31, 2023 are as follows (in thousands): In-Place Leases Out-of-Market Leases, Net July 1, 2019 through December 31, 2019 $ 7,740 $ (2,155 ) 2020 $ 14,437 $ (4,136 ) 2021 $ 12,341 $ (3,778 ) 2022 $ 11,034 $ (2,945 ) 2023 $ 10,204 $ (2,625 ) Leases The Company’s leases are generally for terms of 15 years or less and may include multiple options to extend the lease term upon tenant election. The Company’s leases typically do not include an option to purchase. Generally, the Company does not expect the value of its real estate assets to be impacted materially at the end of any individual lease term, as the Company is typically able to re-lease the space and real estate assets tend to hold their value over a long period of time. Tenant terminations prior to the lease end date occasionally result in a one-time termination fee based on the remaining unpaid lease payments including variable payments and could be material to the tenant. Many of the Company’s leases have increasing minimum rental rates during the terms of the leases through escalation provisions. In addition, the majority of the Company’s leases provide for separate billings for variable rent, such as, reimbursements of real estate taxes, maintenance and insurance and may include an amount based on a percentage of the tenants’ sales. Total billings related to expense reimbursements from tenants for the three and six months ended June 30, 2019 was $12.3 million and $24.5 million , respectively, which is included in rental revenue on the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). The Company has entered into non-cancelable lease agreements with tenants for space. As of June 30, 2019 , the approximate fixed future minimum rentals for the period from July 1, 2019 through December 31, 2019 , for each of the years ending December 31, 2020 through December 31, 2023 and for the period thereafter are as follows (in thousands): Fixed Future Minimum Rentals July 1, 2019 through December 31, 2019 $ 67,798 2020 134,741 2021 141,508 2022 135,248 2023 121,762 Thereafter 882,738 Total $ 1,483,795 During the six months ended June 30, 2019 and 2018 , the Company did not earn more than 10% of its total rental revenue from any individual tenant.

Equity [Abstract]
DISTRIBUTIONS	DISTRIBUTIONS The Company declared distributions for the months of January 2018 through December 2018 at an amount equal to $0.0541667 per share, per month ( $0.65 per share on an annualized basis). Approximately $0.45 per share of these distributions were designated as a return of a portion of the stockholders’ invested capital as described further below. From January 2018 through February 2019, the Company paid aggregate return of capital distributions (“Return of Capital Distributions”) to stockholders totaling approximately $4.00 per share, which represented a return of a portion of the stockholders’ invested capital. These Return of Capital Distributions were made up of the following: • a $1.05 per share special distribution (the “Special Distribution”) declared to all stockholders of record as of December 30, 2017 and paid in January 2018. The Special Distribution was funded with a portion of the net proceeds received from the strategic sale of six assets during 2017. • $0.12 per share resulting from a portion of the monthly distributions declared for the months of January 2018 through June 2018, (approximately $0.02 per share, per month), which were designated by our board of directors as a return of a portion of the stockholders’ invested capital and, as such, reduced the stockholders’ remaining investment in the Company. • Approximately $0.33 per share resulting from the monthly liquidating distributions declared for the months of July 2018 through December 2018 ( $0.541667 per share, per month), which were designated as liquidating distributions and, as such, reduced the stockholders’ remaining investment in the Company. • a $2.50 per share designated liquidating distribution declared to all stockholders of record as of February 13, 2019 and paid in February 2019. On July 17, 2018, in connection with the stockholder approval of the Plan of Liquidation, the board of directors determined to suspend the distribution reinvestment plan indefinitely effective as of August 31, 2018. As a result of the suspension of the distribution reinvestment plan, all distributions paid after August 31, 2018 were paid to stockholders in cash. Additionally, because the Company already sold a significant number of assets and its expectation is to sell all of its remaining assets in the time frame set forth under its Plan of Liquidation, the Company determined to stop paying monthly distributions for periods after December 2018. The Company intends to fund all future liquidating distributions with proceeds from the sale of its remaining properties in addition to any distributable cash from the operating income of its remaining properties. The table below outlines the Company’s total distributions declared to stockholders and noncontrolling interests for each of the quarters ended during 2019 and 2018 , including the breakout between the distributions declared in cash and those reinvested pursuant to the Company’s distribution reinvestment plan (in thousands).

Fair Value Measurements

Fair Value Measurements	6 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Financial Instruments Fair Value Disclosures As of June 30, 2019 , the Company estimated that the fair value of its notes payable, which had a book value (excluding any unamortized discount or premium) of $782.5 million , was $783.4 million . As of December 31, 2018 , the Company estimated that the fair value of its notes payable, which had a book value of $678.1 million , was $679.3 million . 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 June 30, 2019 , 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. 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 inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy. 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. The Company determined that one of its properties was impaired for the six months ended June 30, 2019 as a result of deteriorating market conditions. For the year ended December 31, 2018 , the Company determined that three of its properties ( two of which were measured using executed purchase and sale agreements which are considered level 2 inputs, and one of which was measured using level 3 inputs) were 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, these properties were written down to fair value. The following table summarizes activity for the properties measured at fair value, on a non-recurring basis as of June 30, 2019 and December 31, 2018 (in thousands). Basis of Fair Value Measurements As of Description Fair Value of Assets Quoted Prices (Level 1) Significant (Level 2) Significant (Level 3) Impairment Loss June 30, 2019 Investment property $ 120,896 $ — $ — $ 120,896 $ 7,185 December 31, 2018 Investment property $ 138,550 $ — $ 68,250 $ 70,300 $ 19,180 The Company’s estimated fair value of the property measured using level 3 inputs was based on comparisons 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 June 30, 2019 include: a discount rate of 7.21% ; a capitalization rate of 6.25% ; stabilized occupancy rate of 91.8% ; and a current market rental rate of $25.00 per square foot. Significant unobservable quantitative inputs used in determining the fair value of the investment property for the period ended December 31, 2018 include: a discount rate of 9.00% ; a capitalization rate of 8.00% ; stabilized occupancy rate of 90.0% ; and a current market rental rate of $25.00 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.

Reportable Segments

Reportable Segments	6 Months Ended

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. The Company’s reporting segments consist of the following, based on the Company’s investments as of June 30, 2019 : • Domestic office investments ( 3 investments) • Domestic other investments ( 4 investments) • International office investments ( 4 investments) • International other investments ( 1 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): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Total Revenue Domestic office investments $ 14,650 $ 33,033 $ 31,492 $ 65,696 Domestic other investments 18,604 25,172 37,264 45,275 International office investments 11,972 17,654 23,963 39,163 International other investments 835 9,283 1,575 19,507 Total Revenue $ 46,061 $ 85,142 $ 94,294 $ 169,641 For the three and six months ended June 30, 2019 and 2018 the Company’s total revenue was attributable to the following countries: Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Total Revenue United States 72 % 69 % 73 % 66 % United Kingdom 15 % 7 % 14 % 9 % Poland 5 % 6 % 5 % 7 % Russia 5 % 3 % 5 % 3 % France 3 % 1 % 3 % 1 % Australia — % 8 % — % 8 % Germany — % 6 % — % 6 % For the three and six months ended June 30, 2019 and 2018 , the Company’s property revenues in excess of expenses by segment was as follows (in thousands): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Property revenues in excess of expenses (1) Domestic office investments $ 8,704 $ 20,758 $ 18,871 $ 41,660 Domestic other investments 11,229 16,530 22,632 27,970 International office investments 5,935 10,118 11,533 21,350 International other investments 578 6,346 979 13,617 Property revenues in excess of expenses $ 26,446 $ 53,752 $ 54,015 $ 104,597 (1) Revenues less property operating expenses, real property taxes and property management fees.

Accounting Policies [Abstract]
Revenue Recognition	Revenue Recognition Rental payments are generally paid by the tenants prior to the beginning of each month or quarter to which they relate. As of June 30, 2019 and December 31, 2018 , respectively, the Company recorded liabilities of $11.7 million and $15.5 million related to prepaid rental payments, which were included in other liabilities in the accompanying Condensed 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 $41.6 million and $44.0 million as of June 30, 2019 and December 31, 2018 , 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 Condensed 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. Parking revenue represents amounts generated from contractual and transient parking and is recognized in accordance with contractual terms or as services are rendered.
Recently Adopted and New Accounting Pronouncements	Recently Adopted Accounting Pronouncements In February 2016, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2016-02 which requires companies that lease assets to recognize on the balance sheet the right-of-use assets and related lease liabilities (“ASC 842”). The accounting by companies that own the assets leased by the lessee (the lessor) is largely unchanged from previous GAAP. The Company adopted ASC 842 as of January 1, 2019, and is using the modified retrospective approach. No adjustment to opening retained earnings was required. In July 2018, the FASB issued ASU 2018-11, which allows lessors to account for lease and non-lease components by class of underlying assets, as a single lease component if certain criteria are met. Also, the new standard indicates that companies are permitted to recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption in lieu of restating prior periods in accordance with ASC 842 and provides other optional practical expedients. Upon adoption, the Company has elected the following practical expedients: • The transition method in which the application date of January 1, 2019 is the beginning of the reporting period that the Company first applied the new guidance. • The practical expedient package which allows an entity not to reassess (1) whether any expired or existing contracts are or contain leases; (2) the lease classification for any expired or existing leases; (3) initial direct costs for any existing leases. • As an accounting policy election, a lessor may choose not to separate the non-lease components, by class of underlying assets, from the lease components and instead account for both types of components as a single component under certain conditions. • As an accounting policy election, a lessee may choose not to separate the non-lease components, by class of underlying assets, from the lease components and instead account for both types of components as a single component. The Company elected to apply the practical expedient for all of its leases to account for the lease and non-lease components as a single, combined operating lease component. The Company completed its evaluation of the impact that the adoption of ASC 842 will have on the Company’s consolidated financial statements relating to its leases from both the lessee and lessor perspective. Based on the Company’s analysis, the Company identified the following changes to result from its adoption of ASC 842: Lessor Accounting • The Company is entitled to receive tenant reimbursements for operating expenses for common area maintenance (“CAM”). Based on guidance in these ASUs, CAM reimbursement revenue is defined as a non-lease component, which would be accounted for in accordance with ASC 606. However, the Company elected to apply the practical expedient for all of its leases to account for the lease and non-lease components as a single, combined operating lease component. • Capitalization of leasing costs is limited to initial direct costs. Initial direct costs have been defined as incremental costs of a lease that would not have been incurred if the lease had not been obtained. Legal costs are no longer capitalized, but expensed as incurred. There is no change in the Company’s accounting for lease inducements and commissions. • The Company’s existing leases continue to be classified as operating leases, however, leases entered into or modified after January 1, 2019 may be classified as either operating or sales-type leases, based on specific classification criteria. The Company believes all of its leases will continue to be classified as operating leases, and all operating leases will continue to have a similar pattern of recognition as under current GAAP. Lessee Accounting • The Company has two ground lease agreements in which the Company is the lessee for land underneath 25 Cabot Square. The Company previously recognized an amount related to these ground leases as part of the allocation of the purchase price of 25 Cabot Square, which was recorded to intangible lease assets, net. The leases have remaining terms of 198 years and 973 years . Upon adoption of ASC 842 on January 1, 2019, the Company reclassified approximately £58.3 million (approximately $74.4 million converted using an exchange rate of $1.28 per GBP on January 1, 2019) from intangible lease assets, net to right-of-use asset in the Company’s Condensed Consolidated Balance Sheets. No lease liability was recorded since the payments required under the lease are immaterial. • The Company has a ground lease agreement in which the Company is the lessee for land underneath New City that is currently accounted for as an operating lease. The lease currently ends in December 2089 and has fixed payments. The rental expense associated with this lease was $0.2 million and $0.2 million for the six months ended June 30, 2019 , and 2018 , respectively. The Company previously recognized an amount related to this ground lease as part of the allocation of the purchase price of New City, which was recorded to intangible lease assets, net. Upon adoption of ASC 842 on January 1, 2019, the Company recorded a right-of-use asset and lease liability of approximately $3.6 million in right-of-use asset, net and other liabilities, respectively, in the Company’s Condensed Consolidated Balance Sheets and reclassified an additional 65.1 million Polish zloty (“PLN”) (approximately $17.3 million converted using an exchange rate of $0.27 per PLN on January 1, 2019) from intangible lease assets, net to right-of-use asset in the Company’s Condensed Consolidated Balance Sheets. The Company’s estimate of the amount of the right-of-use asset and lease liability included assumptions for the discount rate, which is based on the incremental borrowing rate of the lease contract. The incremental borrowing rate is the rate of interest that a lessee would have to pay to borrow on a collateralized basis over a term similar to the lease. Since the term of the New City ground lease is much longer than a typical borrowing, we derived the incremental borrowing rate of 6.4% , as the spread in a current financing quote for the property plus the applicable base rate corresponding to the longest term available in the base rate market. New Accounting Pronouncements In August 2018, the FASB issued ASU No. 2018-13, "Changes to the Disclosure Requirements for Fair Value Measurement." This ASU amends and removes several disclosure requirements including the valuation processes for Level 3 fair value measurements. The ASU also modifies some disclosure requirements and requires additional disclosures for changes in unrealized gains and losses included in other comprehensive income for recurring Level 3 fair value measurements and requires the range and weighted average of significant unobservable inputs used to develop Level 3 fair value measurements. The ASU is effective for fiscal years beginning after December 15, 2019, including interim periods therein. Early adoption is permitted for any eliminated or modified disclosures upon issuance of this ASU. The Company is currently assessing the impact the adoption of this guidance will have on its financial statements.
Fair Value Measurements	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 June 30, 2019 , 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. 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 inputs associated with the valuation of long-lived assets are generally included in Level 3 of the fair value hierarchy.
Impairment of Investment Property	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.
