Accounting Policies [Abstract]
DESCRIPTION OF BUSINESS	1. DESCRIPTION OF BUSINESS Unless the context otherwise requires, the “Company” refers to Industrial Property Trust Inc. and its consolidated subsidiaries. The Company is a Maryland corporation formed on August 28, 2012. The Company was formed to make equity and debt investments in income-producing real estate assets consisting primarily of high-quality distribution warehouses and other industrial properties that are leased to creditworthy corporate customers. Creditworthiness does not necessarily mean that the Company’s customers will be investment grade and much of the Company’s customer base is currently comprised of and is expected to continue to be comprised of non-rated and non-investment grade customers. Although the Company intends to focus investment activities primarily on distribution warehouses and other industrial properties, the charter and bylaws do not preclude it from investing in other types of commercial property, real estate debt, or real estate-related equity securities. As of December 31, 2018 , the Company owned and managed, either directly or through its minority ownership interests in its joint venture partnerships, a real estate portfolio that included 285 industrial buildings. The Company operates as one reportable segment comprised of industrial real estate. The Company currently operates and has elected to be treated as a real estate investment trust (“REIT”) for U.S. federal income tax purposes beginning with its taxable year ended December 31, 2013, and the Company intends to continue to operate in accordance with the requirements for qualification as a REIT. The Company utilizes an Umbrella Partnership Real Estate Investment Trust (“UPREIT”) organizational structure to hold all or substantially all of its properties and securities through an operating partnership, Industrial Property Operating Partnership LP (the “Operating Partnership”), of which the Company is the sole general partner and a limited partner.

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of management, the accompanying consolidated financial statements contain all adjustments and eliminations, consisting only of normal recurring adjustments necessary for a fair presentation in conformity with GAAP. Basis of Consolidation The consolidated financial statements include the accounts of Industrial Property Trust Inc., the Operating Partnership, and its wholly-owned subsidiaries, as well as amounts related to noncontrolling interests. See “Noncontrolling Interests” below for further detail concerning the accounting policies regarding noncontrolling interests. All material intercompany accounts and transactions have been eliminated. Use of Estimates GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from these estimates. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the period they are determined to be necessary. Reclassifications Certain items in the Company’s consolidated balance sheet for 2017 have been reclassified to conform to the 2018 presentation. Future estimated distribution fees payable have been reclassified from due to affiliates and are presented separately in the consolidated balance sheets. Certain items in the Company’s consolidated income statement and consolidated statement of cash flows for 2017 and 2016 have been reclassified to conform to the 2018 presentation. Net loss on sell down of joint venture partnership ownership interest has been reclassified to equity in (income) loss of unconsolidated joint venture partnerships. Investment in Real Estate Properties The Company first determines whether an acquisition constitutes a business or asset acquisition. Upon either a business or asset acquisition, the purchase price of a property is allocated to land, building, and intangible lease assets and liabilities based on their relative fair value. The allocation of the purchase price to building is based on management’s estimate of the property’s “as-if” vacant fair value. The “as-if” vacant fair value is determined by using all available information such as the replacement cost of such asset, appraisals, property condition reports, market data and other related information. The allocation of the purchase price to intangible lease assets represents the value associated with the in-place leases, which may include lost rent, leasing commissions, tenant improvements, legal and other related costs. The allocation of the purchase price to above-market lease assets and below market lease liabilities results from in-place leases being above or below management’s estimate of fair market rental rates at the acquisition date and are measured over a period equal to the remaining term of the lease for above-market leases and the remaining term of the lease, plus the term of any below-market fixed-rate renewal option periods, if applicable, for below market leases. Intangible lease assets, above-market lease assets, and below-market lease liabilities are collectively referred to as “intangible lease assets and liabilities.” Properties that are probable to be sold are to be designated as “held for sale” on the balance sheet when certain criteria are met. If any debt is assumed in an acquisition, the difference between the fair value and the face value of debt is recorded as a premium or discount and amortized to interest expense over the life of the debt assumed. During the years ended December 31, 2018 and 2017, there was no debt assumed in connection with acquisitions. Beginning January 1, 2017, transaction costs associated with the acquisition of a property (including the acquisition fees paid to the Advisor and its affiliates) are capitalized as incurred in an asset acquisition and are allocated to land, building, and intangible lease assets on a relative fair value basis. Prior to January 1, 2017, costs associated with the acquisition of a property (including acquisition fees paid to the Advisor and its affiliates) were expensed as incurred. For the years ended December 31, 2018 and 2017, $1.2 million and $7.9 million , respectively, of acquisition costs (including the acquisition fees paid to the Advisor and its affiliates) were capitalized in net investment in real estate properties on the consolidated balance sheets instead of expensed as in prior periods. The results of operations for acquired properties are included in the consolidated statements of operations from their respective acquisition dates. Intangible lease assets are amortized to real estate-related depreciation and amortization over the remaining lease term. Above-market lease assets are amortized as a reduction in rental revenues over the remaining lease term and below-market lease liabilities are amortized as an increase in rental revenues over the remaining lease term, plus any applicable fixed-rate renewal option periods. The Company expenses any unamortized intangible lease asset or records an adjustment to rental revenue for any unamortized above-market lease asset or below-market lease liability when a customer terminates a lease before the stated lease expiration date. Land, building, building and land improvements, tenant improvements, lease commissions, and intangible lease assets and liabilities, which are collectively referred to as “real estate assets,” are stated at historical cost less accumulated depreciation and amortization. Costs associated with the development and improvement of the Company’s real estate assets are capitalized as incurred. These costs include capitalized interest and development acquisition fees. Other than the transaction costs associated with the acquisition of a property described above, the Company does not capitalize any other costs, such as taxes, salaries or other general and administrative expenses. See “Capitalized Interest” below for additional detail. Costs incurred in making repairs and maintaining real estate assets are expensed as incurred. Real estate-related depreciation and amortization are computed on a straight-line basis over the estimated useful lives as described in the following table: Land Not depreciated Building 20 to 40 years Building and land improvements 5 to 20 years Tenant improvements Lesser of useful life or lease term Lease commissions Over lease term Intangible lease assets Over lease term Above-market lease assets Over lease term Below-market lease liabilities Over lease term, including below-market fixed-rate renewal options Real estate assets that are determined to be held and used will be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, and the Company will evaluate the recoverability of such real estate assets based on estimated future cash flows and the estimated liquidation value of such real estate assets, and provide for impairment if such undiscounted cash flows are insufficient to recover the carrying amount of the real estate asset. If impaired, the real estate asset will be written down to its estimated fair value. Investment in Unconsolidated Joint Venture Partnerships The Company analyzes its investments under GAAP guidance to determine if any joint venture partnership is a variable interest entity (“VIE”) and whether the requisite substantial participating rights described in the GAAP guidance are held by the partners not affiliated with the Company. If a joint venture partnership is not a VIE and the partners hold substantial participating rights, the Company accounts for its investment in the joint venture partnership under the equity method. Under the equity method, the investment is initially recorded at cost and subsequently adjusted to reflect the Company’s proportionate share of equity in the joint venture partnership’s income (loss) and distributions, which is included in investment in unconsolidated joint venture partnership on its consolidated balance sheets. The Company additionally recognizes its proportionate share of the ongoing income or loss of the unconsolidated joint venture partnership in equity in loss of unconsolidated joint venture partnership on the consolidated statements of operations. The Company evaluates its investments in the unconsolidated joint venture partnerships for impairment whenever events or changes in circumstances indicate that there may be an other-than-temporary decline in value. To do so, the Company calculates the estimated fair value of the investment using various valuation techniques, including, but not limited to, discounted cash flow models, the Company’s intent and ability to retain its investment in the entity, the financial condition and long-term prospects of the entity, and the expected term of the investment. If the Company determined any decline in value is other-than-temporary, the Company would recognize an impairment charge to reduce the carrying value of its investment to fair value. No impairment losses were recorded related to the unconsolidated joint venture partnerships for the years ended December 31, 2018 , 2017 , and 2016 . See “ Note 6 ” for additional information regarding the unconsolidated joint venture partnerships. Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and highly liquid investments with original maturities at the acquisition date of three months or less. Straight-line Rent and Tenant Receivables Straight-line rent and tenant receivables include all straight-line rent and accounts receivable, net of allowances. The Company maintains an allowance for estimated losses that may result from the inability of certain of its customers to make required payments. If a customer fails to make contractual payments beyond any allowance, the Company may recognize additional bad debt expense in future periods equal to the net outstanding balances. As of December 31, 2018 , and 2017 the Company’s allowance for doubtful accounts was approximately $0.4 million and $0.3 million , respectively. Derivative Instruments The Company records its derivative instruments in the consolidated balance sheets at fair value. The Company’s derivative instruments are designated as cash flow hedges and are used to hedge exposure to variability in expected future cash flows, such as future interest payments. For cash flow hedges, the changes in fair value of the derivative instrument that represent changes in expected future cash flows, which are effectively hedged by the derivative instrument, are initially reported as other comprehensive income in the consolidated statements of equity until the derivative instrument is settled. Upon settlement, the effective portion of the hedge is recognized as other comprehensive income and amortized over the term of the designated cash flow or transaction the derivative instrument was intended to hedge. As such, the effective portion of the hedge impacts net income in the same period as the hedged item. The change in value of any derivative instrument that is deemed to be ineffective is charged directly to net income when the determination of hedge ineffectiveness is made. For purposes of determining hedge ineffectiveness, management estimates the timing and potential amount of future interest payments in order to estimate the cash flows of the designated hedged item or transaction. The Company does not use derivative instruments for trading or speculative purposes. Debt Issuance Costs Debt issuance costs include fees and costs incurred to obtain long-term financing. These fees and costs are amortized to interest expense over the terms of the related credit facilities. Unamortized debt issuance costs are written off if debt is retired before its maturity date. Accumulated amortization of debt issuance costs was approximately $7.8 million and $5.4 million as of December 31, 2018 and 2017 , respectively. The Company’s interest expense for the years ended December 31, 2018 , 2017 and 2016 included $2.4 million , $2.3 million and $1.9 million , respectively, of amortization of financing costs. Capitalized Interest The Company capitalizes interest as a cost of development. Capitalization of interest for a particular asset begins when activities necessary to get the asset ready for its intended use are in progress and when interest costs have been incurred. Capitalization of interest ceases when the project is substantially complete and ready for occupancy. For the years ended December 31, 2018 , 2017 and 2016 , approximately $1.7 million , $2.5 million and $1.5 million of interest was capitalized, respectively. Distribution Fees Distribution fees are paid monthly. Distribution fees are accrued upon the issuance of Class T shares. The Company accrues for: (i) the monthly amount payable as of the balance sheet date, and (ii) the estimated amount of distribution fees to be paid in future periods based on the Class T shares outstanding as of the balance sheet date. The accrued distribution fees are reflected in additional paid-in capital in stockholders’ equity. See “ Note 12 ” for additional information regarding when distribution fees become payable. Noncontrolling Interests Due to the Company’s control of the Operating Partnership through its sole general partner interest and its limited partner interest, the Company consolidates the Operating Partnership. The limited partner interests not owned by the Company are presented as noncontrolling interests in the consolidated financial statements. The noncontrolling interests are reported on the consolidated balance sheets within permanent equity, separate from stockholders’ equity. As the limited partner interests do not participate in the profits and losses of the Operating Partnership, there is no net income or loss attributable to the noncontrolling interests on the consolidated statements of operations. Noncontrolling interests also represent the portion of equity in the acquired subsidiary real estate investment trusts (“Subsidiary REITs”), that the Company does not own. Such noncontrolling interests are equity instruments presented in the consolidated balance sheets as noncontrolling interests within permanent equity. See “ Note 11 ” for additional information regarding the Subsidiary REITs. Revenue Recognition The Company records rental revenue on a straight-line basis over the full lease term. Certain properties have leases that offer the tenant a period of time where no rent is due or where rent payments change during the term of the lease. Accordingly, the Company records receivables from tenants for rent that the Company expects to collect over the remaining lease term rather than currently, which are recorded as a straight-line rent receivable. When the Company acquires a property, the term of each existing lease is considered to commence as of the acquisition date for purposes of this calculation. Tenant reimbursement revenue includes payments and amounts due from tenants pursuant to their leases for real estate taxes, insurance and other recoverable property operating expenses and is recognized as rental revenue in the period the applicable expenses are incurred. For the years ended December 31, 2018 , 2017 and 2016 , tenant reimbursement revenue recognized in rental revenues was approximately $58.8 million , $52.9 million and $41.4 million , respectively. In connection with property acquisitions, the Company may acquire leases with rental rates above or below estimated market rental rates. Above-market lease assets are amortized as a reduction to rental revenue over the remaining lease term, and below-market lease liabilities are amortized as an increase to rental revenue over the remaining lease term, plus any applicable fixed-rate renewal option periods. The Company expenses any unamortized intangible lease asset or records an adjustment to rental revenue for any unamortized above-market lease asset or below-market lease liability by reassessing the estimated remaining useful life of such intangible lease asset or liability when it becomes probable a customer will terminate a lease before the stated lease expiration date. Upon the disposition of an asset, the Company will evaluate the transaction to determine if control of the asset, as well as other specified criteria, has been transferred to the buyer to determine proper timing of recognizing gains or losses. Organization and Offering Expenses Organization and offering expenses are accrued by the Company only to the extent that the Company is successful in raising gross offering proceeds. If the Company does not raise additional equity proceeds, no additional amounts will be payable by the Company to the Advisor for reimbursement of cumulative organization and offering expenses. Organization costs are expensed in the period they become reimbursable and offering expenses associated with the Company’s public offerings are recorded as a reduction of gross offering proceeds in additional paid-in capital. See “ Note 12 ” for additional information regarding when organization and offering expenses become reimbursable. Income Taxes The Company currently operates as a REIT under the Internal Revenue Code of 1986, as amended, for federal income tax purposes, and elected to be treated as a REIT beginning with its taxable year ended December 31, 2013. As a REIT, the Company generally is not subject to federal income taxes on net income it distributes to its stockholders. The Company intends to make timely distributions sufficient to satisfy the annual distribution requirements. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to federal income tax on its taxable income at regular corporate tax rates. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property and federal income and excise taxes on its undistributed income. Net Loss Per Common Share The Company computes net loss per common share by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period for each class. There are no class specific expenses and each class of common stock shares equally in the profits and losses of the Company. There were no dilutive shares for the years ended December 31, 2018 , 2017 and 2016 . Fair Value Measurements Fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. Fair value measurements are categorized into one of three levels of the fair value hierarchy based on the lowest level of significant input used. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is 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. Considerable judgment and a high degree of subjectivity are involved in developing these estimates. These estimates may differ from the actual amounts that the Company could realize upon settlement. The fair value hierarchy is as follows: Level 1—Quoted (unadjusted) prices in active markets for identical assets or liabilities. Level 2—Other observable inputs, either directly or indirectly, other than quoted prices included in Level 1, including: • Quoted prices for similar assets/liabilities in active markets; • Quoted prices for identical or similar assets/liabilities in non-active markets (e.g., few transactions, limited information, non-current prices, high variability over time); • Inputs other than quoted prices that are observable for the asset/liability (e.g., interest rates, yield curves, volatilities, default rates); and • Inputs that are derived principally from or corroborated by other observable market data. Level 3—Unobservable inputs that cannot be corroborated by observable market data. Recently Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which provides guidance for revenue recognition and supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition.” The standard is based on the principle that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The guidance specifically excludes revenue derived from lease contracts from its scope. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The Company adopted the standard when it became effective for the Company, as of the reporting period beginning January 1, 2018. The Company elected the package of practical expedients, and accordingly did not reallocate contract consideration to lease components within the scope of the existing lease guidance when it adopted ASU 2014-09. Effective January 1, 2018, the Company also adopted ASU No. 2017-05, “Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” (ASU 2017-05). Through the evaluation and implementation process, the Company has determined the key revenue stream that could be impacted by ASU 2014-09, as amended by ASU 2017-05, is the gain on disposition of real estate reported on the consolidated statements of operation. The Company previously recognized revenue from asset sales upon transfer of title at the time of closing. After adoption of ASU 2014-09, the Company will evaluate the transaction to determine if control of the asset, as well as other specified criteria, has been transferred to the buyer to determine property timing of revenue recognition, as well as transaction price allocation. The adoption of ASU 2014-09 did not have a significant impact on the Company’s consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”), which requires: (i) all equity investments to be measured at fair value with changes in fair value recognized in net income; (ii) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; and (iii) eliminates the requirement for public entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. Early adoption is permitted for the accounting guidance on financial liabilities under the fair value option. The Company adopted this guidance effective January 1, 2018. The adoption of this guidance did not have a significant impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”), which modifies the disclosure requirements on fair value measurements by removing, modifying, or adding certain disclosures. Certain disclosures in ASU 2018-13 are required to be applied on a retrospective basis and others on a prospective basis. The Company adopted this guidance effective September 30, 2018. The adoption of ASU 2018-13 did not have a significant impact on the Company’s consolidated financial statements. Recently Issued Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, “Leases (Subtopic 842)” (“ASU 2016-02”), which provides guidance for greater transparency in financial reporting by organizations that lease assets such as real estate, airplanes and manufacturing equipment by requiring such organizations to recognize lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The accounting for lessors will remain largely unchanged from current GAAP; however, the standard requires that lessors expense, on an as-incurred basis, certain initial direct costs that are not incremental in negotiating a lease. Under existing standards, certain of these costs are capitalizable and therefore this new standard will result in certain of these costs being expensed as incurred after adoption. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted the standard when it became effective for the Company, as of the reporting period beginning January 1, 2019, and the Company elected the practical expedients available for implementation under the standard. Under the practical expedients election, the Company would not be required to reassess: (i) whether an expired or existing contract meets the definition of a lease; (ii) the lease classification at the adoption date for expired or existing leases; and (iii) whether costs previously capitalized as initial direct costs would continue to be amortized. The standard also will require new disclosures within the notes accompanying the consolidated financial statements. Additionally, in January 2018, the FASB issued ASU No. 2018-01, “Leases (Subtopic 842): Land Easement Practical Expedient for Transition to Topic 842” (“ASU 2018-01”), which updates ASU 2016-02 to include land easements under the updated guidance, including the option to elect the practical expedient discussed above. The Company also adopted ASU 2018-01 when it became effective for the Company, as of the reporting period beginning January 1, 2019, and the Company elected the practical expedients available for implementation under the standard. In addition, in December 2018, the FASB issued ASU No. 2018-20, “Narrow—Scope Improvements for Lessors” (“ASU 2018-20”), which updates 2016-02 by providing the option to elect a practical expedient for lessors to exclude sales and other similar taxes from the transaction price of the contract, requires lessors to exclude from revenue and expense lessor costs paid directly to a third party by lessees, and clarifies lessors’ accounting for variable payments related to both lease and nonlease components. The Company adopted ASU 2018-20 when it became effective for the Company, as of the reporting period beginning January 1, 2019, and the Company elected the practical expedients available for implementation under the standard. The adoption of these standards did not have a material effect on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities.” The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of early adopting the new standard using a modified retrospective transition method in any interim period after issuance of the update, or alternatively requires adoption for fiscal years beginning after December 15, 2018. This adoption method will require the Company to recognize the cumulative effect of initially applying the ASU as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. Based on the Company’s analysis, the adoption of ASU 2017-12 will not have a material effect on its consolidated financial statements.

Due to a change in management’s estimate of the intended hold period of these properties, the Company reevaluated the fair value of the properties and determined that the net book value of the properties exceeded the estimated future undiscounted cash flows and the estimated liquidation value less costs to sell the properties, resulting in the impairment. The Company determined that its impairments are non-recurring fair value measurements that fall within Level 3 of the fair value hierarchy. See “ Note 2 ” for further discussion of the fair value hierarchy. There were no impairment charges recorded for the years ended December 31, 2018 and 2017.

Debt Disclosure [Abstract]
DEBT	7. DEBT The Company’s consolidated indebtedness is currently comprised of borrowings under its line of credit, term loans and mortgage notes. Borrowings under the non-recourse mortgage notes are secured by mortgages or deeds of trust and related assignments and security interests in collateralized and certain cross-collateralized properties, which are generally owned by single purpose entities. A summary of the Company’s debt is as follows: Weighted-Average Balance as of ($ in thousands) December 31, 2018 December 31, 2017 Maturity Date December 31, 2018 December 31, 2017 Line of credit (1) 3.38 % 2.81 % January 2020 $ 324,000 $ 275,000 Term loan (2) 2.65 2.65 January 2021 350,000 350,000 Term loan (3) 4.05 3.46 May 2022 150,000 150,000 Fixed-rate mortgage notes (4) 3.36 3.36 July 2020 - December 2025 721,526 722,880 Total principal amount / weighted-average (5) 3.27 % 3.10 % $ 1,545,526 $ 1,497,880 Less unamortized debt issuance costs $ (6,702 ) $ (8,735 ) Total debt, net $ 1,538,824 $ 1,489,145 Gross book value of properties encumbered by debt $ 1,147,963 $ 1,153,150 (1) The effective interest rate is calculated based on either: (i) the London Interbank Offered Rate (“LIBOR”) multiplied by a statutory reserve rate plus a margin ranging from 1.40% to 2.30% ; or (ii) an alternative base rate plus a margin ranging from 0.40% to 1.30% , each depending on the Company’s consolidated leverage ratio. The weighted-average effective interest rate is the all-in interest rate, including the effects of interest rate swap agreements relating to $150.0 million in borrowings under this line of credit. As of December 31, 2018 , the unused and available portions under the line of credit were both $175.5 million . The line of credit is available for general corporate purposes, including but not limited to the acquisition and operation of permitted investments. (2) The effective interest rate was calculated based on either: (i) LIBOR multiplied by a statutory reserve rate, plus a margin ranging from 1.35% to 2.20% ; or (ii) an alternative base rate plus a margin ranging from 0.35% to 1.20% , each depending on the Company’s consolidated leverage ratio. The weighted-average effective interest rate is the all-in interest rate, including the effects of interest rate swap agreements. This term loan is available for general corporate purposes, including but not limited to the acquisition and operation of permitted investments. (3) As of December 31, 2017, the effective interest rate was calculated based on either: (i) LIBOR multiplied by a statutory reserve rate, plus a margin ranging from 1.60% to 2.50% ; or (ii) an alternative base rate plus a margin ranging from 0.60% to 1.50% , each depending on the Company’s consolidated leverage ratio. On June 20, 2018, the Company amended the terms of this term loan agreement. As of December 31, 2018 , the effective interest rate is calculated based on either: (i) LIBOR multiplied by a statutory reserve rate, plus a margin ranging from 1.30% to 2.15% ; or (ii) an alternative base rate plus a margin ranging from 0.30% to 1.15% , each depending on the Company’s consolidated leverage ratio. The weighted-average effective interest rate is the all-in interest rate. This term loan is available for general corporate purposes, including but not limited to the acquisition and operation of permitted investments. (4) Interest rates range from 2.94% to 3.65% , which includes the effects of an interest rate swap agreement relating to a variable-rate mortgage note with an outstanding amount of $95.6 million and $97.0 million as of December 31, 2018 and December 31, 2017 , respectively. The assets and credit of each of the Company’s consolidated properties pledged as collateral for the Company’s mortgage notes are not available to satisfy the Company’s other debt and obligations, unless the Company first satisfies the mortgage notes payable on the respective underlying properties. (5) The weighted-average remaining term of the Company’s consolidated debt was approximately 3.5 years as of December 31, 2018 , excluding any extension options on the line of credit. As of December 31, 2018 , the principal payments due on the Company’s consolidated debt during each of the next five years and thereafter were as follows: (in thousands) Line of Credit (1) Term Loans Mortgage Notes Total 2019 $ — $ — $ 2,191 $ 2,191 2020 324,000 — 15,259 339,259 2021 — 350,000 6,047 356,047 2022 — 150,000 83,579 233,579 2023 — — 190,472 190,472 Thereafter — — 423,978 423,978 Total principal payments $ 324,000 $ 500,000 $ 721,526 $ 1,545,526 (1) The term of the line of credit may be extended pursuant to a one -year extension option, subject to certain conditions. Debt Covenants The Company’s line of credit, term loans and mortgage note agreements contain various property-level covenants, including customary affirmative and negative covenants. In addition, the line of credit and term loan agreements contain certain corporate level financial covenants, including leverage ratio, fixed charge coverage ratio, and tangible net worth thresholds. The Company was in compliance with its debt covenants as of December 31, 2018 . Derivative Instruments To manage interest rate risk for certain of its variable-rate debt, the Company uses interest rate swaps as part of its risk management strategy. These derivatives are designed to mitigate the risk of future interest rate increases by providing a fixed interest rate for a limited, pre-determined period of time. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for the Company making fixed-rate payments over the life of the interest rate swap agreements without exchange of the underlying notional amount. As of December 31, 2018 , the Company had 11 outstanding interest rate swap agreements, which were associated with $595.6 million of debt, that were designated as cash flow hedges of interest rate risk. Certain of the Company’s variable-rate borrowings are not hedged, and therefore, to an extent, the Company has on-going exposure to interest rate movements. The effective portion of the change in the fair value of derivatives designated and that qualify as cash flow hedges is recorded in accumulated other comprehensive income (loss) (“AOCI”) on the consolidated balance sheets and is subsequently reclassified into earnings as interest expense for the period that the hedged forecasted transaction affects earnings, which is when the interest expense is recognized on the related debt. The ineffective portion of the change in fair value of the derivatives is recognized directly in earnings. For the years ended December 31, 2018 , 2017 and 2016 , there was no hedge ineffectiveness. The Company expects no hedge ineffectiveness in the next 12 months. The following table summarizes the location and fair value of the cash flow hedges on the Company’s consolidated balance sheets: Fair Value as of Notional Balance Sheet December 31, December 31, (in thousands) Interest rate swaps $ 595,626 Other assets $ 16,438 $ 16,872 The following table presents the effect of the Company’s cash flow hedges on the Company’s consolidated financial statements: For the Year Ended (in thousands) 2018 2017 2016 Interest rate swaps: Income recognized in AOCI (effective portion) $ 5,165 $ 3,452 $ 12,217 (Income) loss reclassified from AOCI into income (effective portion) (5,599 ) (671 ) 1,874 Net other comprehensive (loss) income $ (434 ) $ 2,781 $ 14,091

Fair Value Disclosures [Abstract]
FAIR VALUE	8. FAIR VALUE The Company estimates the fair value of its financial instruments using available market information and valuation methodologies it believes to be appropriate for these purposes. Considerable judgment and a high degree of subjectivity are involved in developing these estimates and, accordingly, they are not necessarily indicative of amounts that the Company would realize upon disposition. Fair Value Measurements on a Recurring Basis The following table presents the Company’s financial instruments measured at fair value on a recurring basis: (in thousands) Level 1 Level 2 Level 3 Total Fair Value December 31, 2018 Assets Derivative instruments $ — $ 16,438 $ — $ 16,438 Total assets measured at fair value $ — $ 16,438 $ — $ 16,438 December 31, 2017 Assets Derivative instruments $ — $ 16,872 $ — $ 16,872 Total assets measured at fair value $ — $ 16,872 $ — $ 16,872 The following methods and assumptions were used to estimate the fair value of each class of financial instrument: Derivative Instruments. The derivative instruments are interest rate swaps. The interest rate swaps are standard cash flow hedges whose fair value is estimated using market-standard valuation models. Such models involve using market-based observable inputs, including interest rate curves. The Company incorporates credit valuation adjustments to appropriately reflect both its nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements, which we have concluded are not material to the valuation. Due to the interest rate swaps being unique and not actively traded, the fair value is classified as Level 2. See “ Note 7 ” above for further discussion of the Company’s derivative instruments. Nonrecurring Fair Value of Financial Measurements As of December 31, 2018 and 2017 , the fair values of cash and cash equivalents, restricted cash, tenant receivables, due from/to affiliates, accounts payable and accrued liabilities, and distributions payable approximate their carrying values due to the short-term nature of these instruments. The table below includes fair values for certain of the Company’s financial instruments for which it is practicable to estimate fair value. The carrying values and fair values of these financial instruments were as follows: As of December 31, 2018 As of December 31, 2017 (in thousands) Carrying Value Fair Value Carrying Value Fair Value Liabilities Line of credit $ 324,000 $ 324,000 $ 275,000 $ 275,000 Term loans 500,000 500,000 500,000 500,000 Mortgage notes 721,526 698,603 722,880 708,615

Income Tax Disclosure [Abstract]
INCOME TAXES	9. INCOME TAXES The Company has concluded that there was no impact related to uncertain tax positions from the results of operations of the Company for the years ended December 31, 2018 , 2017 and 2016 . The U.S. is the major tax jurisdiction for the Company and the earliest tax year subject to examination by the taxing authority is 2014 . Distributions Distributions to stockholders are characterized for federal income tax purposes as: (i) ordinary income; (ii) non-taxable return of capital; or (iii) long-term capital gain. Distributions that exceed the Company’s current and accumulated tax earnings and profits constitute a return of capital and reduce the stockholders’ basis in the common shares. To the extent that a distribution exceeds both current and accumulated earnings and profits and the stockholders’ basis in the common shares, the distributions will generally be treated as a gain from the sale or exchange of such stockholders’ common shares. Under the new tax laws effective January 1, 2018, all distributions (other than distributions designated as capital gain distributions and distributions traceable to distributions from a taxable REIT subsidiary) which are received by a pass-through entity or an individual, are eligible for a 20% deduction from gross income. This eligibility for a 20% deduction will expire as of 2025. At the beginning of each year, the Company notifies its stockholders of the taxability of the distributions paid during the preceding year. The following table summarizes the information reported to investors regarding the taxability of distributions on common stock, as a percentage of total distributions, for the years ended December 31, 2018 , 2017 and 2016 . For the Year Ended (unaudited) 2018 2017 2016 Ordinary income 33.53 % 33.05 % 29.13 % Non-taxable return of capital 60.55 52.10 70.87 Long-term capital gain 5.92 14.85 — Total distribution 100.00 % 100.00 % 100.00 %

The quarterly distribution on Class T shares of common stock is reduced by the distribution fees that are payable monthly with respect to such Class T shares (as calculated on a daily basis). (2) Distribution fees are paid monthly to Black Creek Capital Markets, LLC (the “Dealer Manager”) with respect to Class T shares issued in the primary portion of the public offering only. Refer to “ Note 12 ” for further detail regarding distribution fees. (3) Gross distributions are total distributions before the deduction of distribution fees relating to Class T shares. Redemptions Subject to certain restrictions and limitations, a stockholder may redeem shares of the Company’s common stock for cash at a price that may reflect a discount from the purchase price paid for the shares of common stock being redeemed. Shares of common stock must be held for a minimum of one year , subject to certain exceptions. The Company is not obligated to redeem shares of its common stock under the share redemption program. The Company presently limits the number of shares to be redeemed during any consecutive 12-month period to no more than five percent of the number of shares of common stock outstanding at the beginning of such 12-month period. The Company also limits redemptions in accordance with a quarterly cap. The discount from the purchase price paid for the redeemed shares will vary based upon the length of time that the shares of common stock have been held, as follows: Share Purchase Anniversary Redemption Price as a Percentage of Purchase Price Less than one year No redemption allowed One year 92.5% Two years 95.0% Three years 97.5% Four years and longer 100.0% The following table summarizes the Company’s redemption activity for the periods presented below: For the Year Ended December 31, (in thousands, except per share data) 2018 2017 2016 Number of eligible shares redeemed 2,862 1,906 605 Aggregate amount of shares redeemed $ 28,097 $ 18,345 $ 5,887 Average redemption price per share $ 9.82 $ 9.62 $ 9.73

Noncontrolling Interest [Abstract]
NONCONTROLLING INTERESTS	11. NONCONTROLLING INTERESTS Special Units In September 2012, the Operating Partnership issued 100 partnership units (“Special Units”) to the parent of the Advisor for consideration of $1,000 . The holder of the Special Units does not participate in the profits and losses of the Operating Partnership. Amounts distributable to the holder of the Special Units will depend on operations and the amount of net sales proceeds received from asset dispositions or upon other events. In general, after holders of OP Units, in aggregate, have received cumulative distributions equal to their capital contributions plus a 6.5% cumulative, non-compounded annual pre-tax return on their net contributions, the holder of the Special Units and the holder of OP units will receive 15% and 85% , respectively, of the net sales proceeds received by the Operating Partnership upon the disposition of the Operating Partnership’s assets. In addition, the Special Units will be redeemed by the Operating Partnership, upon the earliest to occur of the following events: a “Liquidity Event” (as defined below); or the occurrence of certain events that result in the termination or non-renewal of the Advisory Agreement, as defined in “ Note 12 ,” between the Advisor, the Company, and the Operating Partnership. A Liquidity Event is defined as (i) a listing of the Company’s common stock on a national securities exchange (or the receipt by the Company’s stockholders of securities that are listed on a national securities exchange in exchange for the Company’s common stock); (ii) a sale, merger or other transaction in which the Company’s stockholders either receive, or have the option to receive, cash, securities redeemable for cash, and/or securities of a publicly traded company; or (iii) the sale of all or substantially all of the Company’s assets where the Company’s stockholders either receive, or have the option to receive, cash or other consideration. The Company has determined that the Special Units are: (i) not redeemable at a fixed or determinable amount on a fixed or determinable date, at the option of the holder, or (ii) redeemable only upon events that are solely within the Company’s control. As a result, the Company classifies the Special Units as noncontrolling interests within permanent equity. Subsidiary REITs During the year ended December 31, 2016, the Company acquired controlling interests in four Subsidiary REITs that each own one building for a total aggregate purchase price of approximately $106.3 million . The Company indirectly owned and controlled the respective managing member of each of the Subsidiary REITs. Noncontrolling interests represent the portion of equity in the Subsidiary REITs that the Company does not own. Such noncontrolling interests are equity instruments presented in the consolidated balance sheet as noncontrolling interests within permanent equity. The noncontrolling interests consisted of redeemable preferred shares with a 12.5% annual preferred dividend. Collectively, the Subsidiary REITs had 500 preferred shares issued and outstanding at a par value of $1,000 per share, for an aggregate amount of $0.5 million . The preferred shares were non-voting and had no rights to income or loss. On November 20, 2017, the preferred shares were redeemed by the respective Subsidiary REITs for $1,000 per share, plus accumulated and unpaid dividends and a redemption premium, for an aggregate amount of approximately $0.6 million . The Subsidiary REITs were subsequently dissolved.

Related Party Transactions [Abstract]
RELATED PARTY TRANSACTIONS	12. RELATED PARTY TRANSACTIONS The Company relies on the Advisor, a related party, to manage the Company’s day-to-day operating and acquisition activities and to implement the Company’s investment strategy pursuant to the terms of the amended and restated advisory agreement, dated August 12, 2018, by and among the Company, the Operating Partnership, and the Advisor, (the “Advisory Agreement”). The current term of the Advisory Agreement ends August 12, 2019, subject to renewals by the Company’s board of directors for an unlimited number of successive one -year periods. The Dealer Manager provides dealer manager services in connection with the Company’s public offering. The Sponsor, which owns the Advisor, is presently directly or indirectly majority owned by the estate of John A. Blumberg, James R. Mulvihill and Evan H. Zucker and/or their respective affiliates, and the Sponsor and the Advisor are jointly controlled by the estate of Mr. Blumberg and Messrs. Mulvihill and Zucker and/or their respective affiliates. The Dealer Manager is presently directly or indirectly majority owned, controlled and/or managed by the estate of Mr. Blumberg, Messrs Mulvihill and/or Mr. Zucker and/or their affiliates. Zucker is the Chairman of our board of directors. The Advisor and the Dealer Manager receive compensation from the Company in the form of fees and expense reimbursements for certain services relating to the Company’s public offering and for the investment and management of the Company’s assets. The following summarizes these fees and expense reimbursements: Sales Commissions. Sales commissions were payable to the Dealer Manager, all of which were reallowed to participating unaffiliated broker dealers, and were equal to up to 7.0% and 2.0% of the gross proceeds from the sale of Class A shares and Class T shares, respectively, in the primary offering. Dealer Manager Fees. Dealer manager fees were payable to the Dealer Manager, a portion of which were reallowed to unaffiliated participating broker dealers, and were equal to up to 2.5% and 2.0% of the gross proceeds from the sale of Class A shares and Class T shares, respectively, in the primary offering. Distribution Fees. Distribution fees are payable to the Dealer Manager with respect to Class T shares issued in the primary portion of the public offering only. All or a portion of the distribution fees are typically reallowed or advanced by the Dealer Manager to unaffiliated participating broker dealers or broker dealers servicing accounts of investors who own Class T shares, referred to as servicing broker dealers. The distribution fees accrue daily, are payable monthly in arrears and will be paid on a continuous basis from year to year. The distribution fees are calculated on outstanding Class T shares issued in the primary portion of the public offering only, in an amount equal to 1.0% per annum of the estimated per share value of Class T shares. In the event an estimated per share value changes, the distribution fee will change immediately with respect to all outstanding Class T shares issued in the primary portion of the public offering, and will be calculated based on the new gross offering price or the new estimated per share value, without regard to the actual price at which a particular Class T share was issued. All shares of a particular class will receive the same quarterly per share distribution, including shares issued pursuant to the Company’s distribution reinvestment plan. The quarterly distributions paid with respect to all outstanding Class T shares will be reduced by the monthly distribution fees calculated with respect to Class T shares issued in the primary offering. The Company does not pay distribution fees with respect to the sale of shares issued pursuant to the Company’s distribution reinvestment plan or shares issued as stock dividends, although the amount of distribution fees payable with respect to Class T shares sold in its primary offering will be allocated among all Class T shares, including shares issued pursuant to the Company’s distribution reinvestment plan and those issued as stock dividends, if any. The Company will cease paying distribution fees with respect to all Class T shares on the earliest to occur of the following: (i) a listing of shares of the Company’s common stock on a national securities exchange; (ii) such Class T shares no longer being outstanding; (iii) the Dealer Manager’s determination that total underwriting compensation from all sources, including dealer manager fees, sales commissions, distribution fees and any other underwriting compensation paid to participating broker dealers with respect to all Class A shares and Class T shares would be in excess of 10.0% of the gross proceeds of the primary portion of the public offering; or (iv) the end of the month in which the transfer agent, on behalf of the Company, determines that total underwriting compensation, including dealer manager fees, sales commissions, and distribution fees with respect to the Class T shares held by a stockholder within his or her particular account, would be in excess of 10.0% of the total gross investment amount at the time of purchase of the primary Class T shares held in such account. Acquisition Fees. Acquisition fees are payable to the Advisor in connection with the acquisition of real property, and will vary depending on whether the Advisor provides development services or development oversight services, each as described below, in connection with the acquisition (including, but not limited to, forward commitment acquisitions) or stabilization (including, but not limited to, development and value-add transactions) of such real property, or both. The Company refers to such properties for which the Advisor provides development services or development oversight services as development real properties. For each real property acquired for which the Advisor does not provide development services or development oversight services, the acquisition fee is an amount equal to 2.0% of the total purchase price of the properties acquired (or the Company’s proportional interest therein), including in all instances real property held in joint venture partnerships or co-ownership arrangements. In connection with providing services related to the development, construction, improvement or stabilization, including tenant improvements of development real properties, which the Company refers to collectively as development services, or overseeing the provision of these services by third parties on the Company’s behalf, which the Company refers to as development oversight services, the acquisition fee, which the Company refers to as the development acquisition fee, will equal up to 4.0% of total project cost, including debt, whether borrowed or assumed (or the Company’s proportional interest therein with respect to real properties held in joint venture partnerships or co-ownership arrangements). If the Advisor engages a third party to provide development services directly to the Company, the third party will be compensated directly by the Company and the Advisor will receive the development acquisition fee if it provides the development oversight services. With respect to an acquisition of an interest in a real estate-related entity, the acquisition fee will equal: (i) 2.0% of the Company’s proportionate share of the purchase price of the property owned by any real estate-related entity in which the Company acquires a majority economic interest or that the Company consolidates for financial reporting purposes in accordance with GAAP; and (ii) 2.0% of the purchase price in connection with the acquisition of any interest in any other real estate-related entity. In addition, the Advisor is entitled to receive an acquisition fee of 1.0% of the purchase price, including any third-party expenses related to such investment, in connection with the acquisition or origination of any type of debt investment or other investment. Asset Management Fees. Asset management fees consist of: (i) a monthly fee of one-twelfth of 0.80% of the aggregate cost (including debt, whether borrowed or assumed, and before non-cash reserves, depreciation and amortization expenses and acquisition fees paid to the Advisor) of each real property asset within the Company’s portfolio (or the Company’s proportional interest therein with respect to real property held in joint venture partnerships, co-ownership arrangements or real estate-related entities in which the Company owns a majority economic interest or that the Company consolidates for financial reporting purposes in accordance with GAAP), provided, that the monthly asset management fee with respect to each real property asset located outside the U.S. that the Company owns, directly or indirectly, will be one-twelfth of 1.20% of the aggregate cost (including debt, whether borrowed or assumed, and before non-cash reserves, depreciation and amortization expenses and acquisition fees paid to the Advisor) of such real property asset; (ii) a monthly fee of one-twelfth of 0.80% of the aggregate cost or investment (before non-cash reserves, depreciation and amortization expenses and acquisition fees paid to the Advisor, as applicable) of any interest in any other real estate-related entity or any type of debt investment or other investment; and (iii) with respect to a disposition, a fee equal to 2.5% of the total consideration paid in connection with the disposition, calculated in accordance with the terms of the Advisory Agreement. The term “disposition” shall include: (i) a sale of one or more assets; (ii) a sale of one or more assets effectuated either directly or indirectly through the sale of any entity owning such assets, including, without limitation, the Company or the Operating Partnership; (iii) a sale, merger, or other transaction in which the stockholders either receive, or have the option to receive, cash, securities redeemable for cash, and/or securities of a publicly traded company; or (iv) a listing of the Company’s common stock on a national securities exchange or the receipt by the Company’s stockholders of securities that are listed on a national securities exchange in exchange for the Company’s common stock. Organization and Offering Expenses. The Company reimburses the Advisor or its affiliates for cumulative organization expenses and for cumulative expenses of its public offerings up to 2.0% of the aggregate gross offering proceeds from the sale of shares in its public offerings. The Advisor or an affiliate of the Advisor is responsible for the payment of the Company’s cumulative organization expenses and offering expenses to the extent that such cumulative expenses exceed the 2.0% organization and offering expense reimbursement for the Company’s public offerings, without recourse against or reimbursement by the Company. Organization and offering expenses are accrued by the Company only to the extent that the Company is successful in raising gross offering proceeds. If the Company does not raise additional offering proceeds, no additional amounts will be payable by the Company to the Advisor for reimbursement of cumulative organization and offering expenses. Organization costs are expensed in the period they become reimbursable and offering costs are recorded as a reduction of gross offering proceeds in additional paid-in capital. Other Expense Reimbursements. In addition to the reimbursement of organization and offering expenses, provided that the Advisor will not be reimbursed for costs of personnel to the extent that such personnel perform services for which the Advisor receives a separate fee, the Company is obligated, subject to certain limitations, to reimburse the Advisor for all of the costs it incurs in connection with the services it provides to the Company, including, without limitation, personnel (and related employment) costs and overhead (including, but not limited to, allocated rent paid to both third parties and an affiliate of the Advisor, equipment, utilities, insurance, travel and entertainment, and other costs) incurred by the Advisor or its affiliates, including, but not limited to, total compensation, benefits and other overhead of all employees involved in the performance of such services. The Advisor may utilize its employees to provide such services and in certain instances those employees may include the Company’s executive officers. Property Management and Leasing Fees. Property management fees may be paid to the Property Manager in an amount equal to a market-based percentage of the annual gross revenues of the applicable property. For each property managed by the Property Manager and owned by the Company, the fee is expected to range from 2.0% to 5.0% of the annual gross revenues. The Company may also pay the Property Manager a separate fee for initially leasing-up its properties, for leasing vacant space in the Company’s real properties and for renewing or extending current leases on the Company’s real properties. Such initial leasing fee will be in an amount that is usual and customary for comparable services rendered to similar assets in the geographic market of the asset (generally expected to range from 2.0% to 8.0% of the projected first year’s annual gross revenues under the lease). The table below summarizes the fees and expenses incurred by the Company for services provided by the Advisor and its affiliates, and by the Dealer Manager related to the services described above, and any related amounts payable: For the Year Ended Payable as of December 31, December 31, (in thousands) 2018 2017 2016 Expensed: Acquisition fees (1) $ — $ — $ 24,489 $ — $ — Asset management fees (2) 23,964 22,470 17,775 69 54 Asset management fees related to dispositions (3) 1,435 496 2,867 — — Other expense reimbursements (4) 5,055 4,301 3,445 510 605 Total $ 30,454 $ 27,267 $ 48,576 $ 579 $ 659 Capitalized: Acquisition fees (1) $ 845 6,148 — $ 62 132 Development acquisition fees (5) 1,281 778 236 61 98 Total $ 2,126 $ 6,926 $ 236 $ 123 $ 230 Additional Paid-In Capital: Sales commissions $ — $ 4,491 $ 16,321 $ — $ — Dealer manager fees — 3,026 10,981 — — Offering costs 568 4,415 8,802 70 116 Distribution fees - current (6) — 5,790 3,853 657 613 Distribution fees - trailing (6) 7,489 — 26,952 18,492 26,071 Total $ 8,057 $ 17,722 $ 66,909 $ 19,219 $ 26,800 (1) Pursuant to new guidance effective January 1, 2017, acquisition-related costs are no longer expensed, but are capitalized as incurred, as the properties we acquire are considered assets rather than businesses under the new standard. Amounts also include the Company’s proportionate share of acquisition fees relating to the joint venture partnerships, which is included in investment in unconsolidated joint venture partnerships on the Company’s consolidated balance sheets. (2) Includes asset management fees other than asset management fees related to dispositions. (3) Asset management fees that relate to the Company’s proportionate share of the disposition fee associated with the dispositions of joint venture partnership properties are included in asset management fees on the Company’s consolidated statement of operations. Asset management fees that relate to the disposition fee associated with dispositions of wholly-owned properties are netted against the respective gain from dispositions and are included in the related net gain amount on the Company’s consolidated statements of operations. (4) Other expense reimbursements include certain expenses incurred in connection with the services provided to the Company under the Advisory Agreement, and is included in general and administrative expenses on the Company’s consolidated statements of operations. These reimbursements include a portion of compensation expenses of individual employees of the Advisor, including certain of the Company’s named executive officers, related to activities for which the Advisor does not otherwise receive a separate fee. A portion of compensation received by certain employees of the Advisor and its affiliates may be in the form of a restricted stock grant awarded by the Company. The Company shows these as reimbursements to the Advisor to the same extent that the Company recognizes the related share-based compensation on its consolidated statements of operations. The Company reimbursed the Advisor approximately $4.0 million , $4.0 million and $3.0 million for the years ended December 31, 2018 , 2017 and 2016 , respectively, related to these compensation expenses. The remaining amount of other expense reimbursements relate to other general overhead and administrative expenses including, but not limited to, allocated rent paid to both third parties and affiliates of the Advisor, equipment, utilities, insurance, travel and entertainment. (5) Development acquisition fees are included in the total development project costs of the respective properties and are capitalized in construction in progress, which is included in net investment in real estate properties on the Company’s consolidated balance sheets. Amounts also include the Company’s proportionate share of development acquisition fees relating to the joint venture partnerships, which is included in investment in unconsolidated joint venture partnerships on the Company’s consolidated balance sheets. (6) The distribution fees accrue daily and are payable monthly in arrears. The monthly amount of distribution fees payable is included in distributions payable on the consolidated balance sheets. Additionally, the Company accrues for estimated trailing amounts payable based on the shares outstanding as of the balance sheet date, which are included in distribution fees payable to affiliates on the consolidated balance sheets. All or a portion of the distribution fees are reallowed or advanced by the Dealer Manager to unaffiliated participating broker dealers or broker dealers servicing accounts of investors who own Class T shares. Joint Venture Partnerships. Each of the BTC I Partnership and the BTC II Partnership (described in “ Note 6 ”) pay fees to a wholly-owned subsidiary of the Advisor that is a special limited partner in the respective joint venture partnership for providing advisory services to the respective joint venture partnership. These advisory services include acquisition and asset management services and, to the extent applicable, development management and development oversight services. In addition, the partnership agreements for the joint venture partnerships contain procedures for making distributions to the parties, including incentive distributions to the special limited partner (which is a subsidiary of the Advisor), which are subject to certain return thresholds being achieved. The obligations of the subsidiaries of the Advisor to provide advisory services to the respective joint venture partnerships will terminate upon termination of the Advisory Agreement with the exception that if the Advisory Agreement is terminated other than for “cause,” the respective subsidiaries of the Advisor will have the option, in their sole discretion, to seek to become the administrative general partner of the respective joint venture partnership; subject to certain conditions. If the subsidiary of the Advisor is made the administrative general partner, then the subsidiary will continue to provide the advisory services and receive the same fees as those to which it was entitled prior to becoming the administrative general partner, but the subsidiary will not control or manage the respective joint venture partnership. As a result of the payment of the fees to the respective subsidiaries of the Advisor by the respective joint venture partnerships, the fees payable to the Advisor pursuant to the Advisory Agreement will be reduced by the product of (i) the fees actually paid to the subsidiaries, and (ii) the percentage interest of the respective joint venture partnership owned by the Company or any entity in which the Company owns an interest. Accordingly, with respect to each joint venture partnership, the aggregate of all fees paid to the respective subsidiary of the Advisor will not, with respect to the interests in the joint venture partnership held by the Company or any entity in which the Company owns an interest, exceed the aggregate amounts otherwise payable to the Advisor pursuant to the Advisory Agreement. For the years ended December 31, 2018 , 2017 , and 2016 , the joint venture partnerships incurred in aggregate approximately $7.5 million , $5.8 million , and $3.6 million , respectively, in acquisition and asset management fees which were paid to the Advisor and its wholly-owned subsidiary pursuant to the respective service agreements. As of December 31, 2018 and 2017 , the Company had amounts due from the joint venture partnerships of approximately $0.2 million and $0.8 million , respectively, which were recorded in due to affiliates on the consolidated balance sheets. Expense Support Agreement In October 2013, the Company entered into an Expense Support and Conditional Reimbursement Agreement (as amended, the “Expense Support Agreement”) with the Operating Partnership and the Advisor. Pursuant to the Expense Support Agreement, the Advisor agreed to defer payment of all or a portion of the asset management fee otherwise payable to it pursuant to the Advisory Agreement if Company-defined funds from operations (“CDFFO” or “Company-defined FFO”), as disclosed in the Company’s quarterly and annual reports, for a particular quarter was less than the aggregate distributions that would have been declared for such quarter assuming daily distributions at a specified quarterly rate per share of common stock (the “Baseline Distributions”). Baseline Distributions were equal to: $0.11250 per share from January 1 through June 30, 2014; $0.11875 per share from July 1 through September 30, 2014; and $0.1250 per share from October 1, 2014 through June 30, 2015. In addition, pursuant to the Expense Support Agreement that was in effect through June 30, 2015, prior to the amendment and restatement of the agreement as described below, the Advisor, in its sole discretion, could elect to fund certain expenses of the Company and the Operating Partnership as expense support payments. Subject to certain conditions and limitations, the Advisor was entitled to reimbursement from the Company for any asset management fees that were deferred and any expense support payments that it made pursuant to the agreement that was in effect through June 30, 2015. The Expense Support Agreement was amended and restated on August 14, 2015, effective from July 1, 2015 through June 30, 2018. Pursuant to the amended and restated Expense Support Agreement, for the period from July 1, 2015 through June 30, 2018, Baseline Distributions means the aggregate distributions that are declared on the Company’s common stock in accordance with the quarterly distribution rate for such quarter; provided that for purposes of calculating the amount of payment by the Advisor pursuant to the agreement, such amount would not exceed the amount that would have been declared on shares of the Company’s common stock assuming a quarterly distribution rate of $0.13515 per share (which is the rate that the Company’s board of directors authorized for the fourth quarter of 2015 and each quarter of 2016 with respect to the Company’s Class A shares and the Company’s Class T shares (less the annual distribution fees that are payable monthly with respect to such Class T shares, as calculated on a daily basis)). Starting with any asset management fees waived pursuant to the agreement on or after July 1, 2015, the Advisor was not entitled to reimbursement from the Company. In addition, from July 1, 2015 through the expiration of the agreement on June 30, 2018, if, in a given calendar quarter, the Company’s CDFFO was less than the Baseline Distributions for such quarter, and the waived asset management fee was not sufficient to satisfy the shortfall for such quarter (a “Deficiency”), the Advisor was required to fund certain expenses of the Company or the Operating Partnership in an amount equal to such Deficiency. Starting with any such payments made by the Advisor on or after July 1, 2015 to cover a Deficiency, the Advisor was not entitled to reimbursement from the Company. The Expense Support Agreement, as amended, governs all waivers and payments made by the Advisor from July 1, 2015 through the second quarter of 2018. The Advisor was entitled to reimbursement of amounts owed to it by the Company prior to July 1, 2015 pursuant to the prior versions of the agreement in accordance with the terms thereof. As of December 31, 2018 , the aggregate amount paid by the Advisor pursuant to the Expense Support Agreement was $7.4 million . Of this amount, the Company has fully reimbursed the $5.4 million that was potentially reimbursable to the Advisor, and there are no additional amounts reimbursable to the Advisor under the Expense Support Agreement. The Expense Support Agreement had an effective term through June 30, 2018 . The table below provides information regarding the fees deferred or waived or expenses supported by the Advisor pursuant to the Expense Support Agreement, as well as any amounts reimbursed to the Advisor by the Company: For the Year Ended (in thousands) 2018 2017 2016 Asset management fees waived $ — $ — $ 267 Reimbursement of previously deferred amounts — — (5,378 ) Total expense repayment to Advisor $ — $ — $ (5,111 ) Transactions with Affiliates In September 2012, the Company sold 20,000 shares of common stock to the Advisor at a price of $10.00 per share. The Company subsequently contributed $2,000 to IPT-GP Inc. (“IPT-GP”), which was a wholly-owned subsidiary of the Company and was the sole general partner of the Operating Partnership until March 2013, when IPT-GP was dissolved as described below. In September 2012, the Operating Partnership issued 19,800 Operating Partnership Units (“OP Units”) to the Company in exchange for $198,000 , representing an approximate 99% limited partner interest. In addition, IPT-GP contributed $2,000 to the Operating Partnership in exchange for 200 OP Units, representing an approximate 1% general partner interest. In March 2013, IPT-GP was dissolved and its 200 OP Units, representing the sole general partner interest in the Operating Partnership, were distributed to the Company as the sole stockholder of IPT-GP. As a result, the Company owns 20,000 OP Units and is the general partner and a limited partner of the Operating Partnership. The rights of the holders of OP Units are limited and do not include the ability to replace the general partner or to approve the sale, purchase or refinancing of the Operating Partnership’s assets. Additionally, the Operating Partnership issued 100 Special Units to Industrial Property Advisors Group LLC, the parent of the Advisor, in exchange for $1,000 . These units are classified as noncontrolling interests. See “ Note 11 ” for additional information regarding the issuance of Special Units.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	12 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”). In the opinion of management, the accompanying consolidated financial statements contain all adjustments and eliminations, consisting only of normal recurring adjustments necessary for a fair presentation in conformity with GAAP.
Basis of Consolidation	Basis of Consolidation The consolidated financial statements include the accounts of Industrial Property Trust Inc., the Operating Partnership, and its wholly-owned subsidiaries, as well as amounts related to noncontrolling interests. See “Noncontrolling Interests” below for further detail concerning the accounting policies regarding noncontrolling interests. All material intercompany accounts and transactions have been eliminated.
Use of Estimates	Use of Estimates GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements. Actual results could differ from these estimates. Estimates and assumptions are reviewed periodically, and the effects of revisions are reflected in the period they are determined to be necessary.
Reclassifications	Reclassifications Certain items in the Company’s consolidated balance sheet for 2017 have been reclassified to conform to the 2018 presentation. Future estimated distribution fees payable have been reclassified from due to affiliates and are presented separately in the consolidated balance sheets. Certain items in the Company’s consolidated income statement and consolidated statement of cash flows for 2017 and 2016 have been reclassified to conform to the 2018 presentation. Net loss on sell down of joint venture partnership ownership interest has been reclassified to equity in (income) loss of unconsolidated joint venture partnerships.
Investment in Real Estate Properties	Investment in Real Estate Properties The Company first determines whether an acquisition constitutes a business or asset acquisition. Upon either a business or asset acquisition, the purchase price of a property is allocated to land, building, and intangible lease assets and liabilities based on their relative fair value. The allocation of the purchase price to building is based on management’s estimate of the property’s “as-if” vacant fair value. The “as-if” vacant fair value is determined by using all available information such as the replacement cost of such asset, appraisals, property condition reports, market data and other related information. The allocation of the purchase price to intangible lease assets represents the value associated with the in-place leases, which may include lost rent, leasing commissions, tenant improvements, legal and other related costs. The allocation of the purchase price to above-market lease assets and below market lease liabilities results from in-place leases being above or below management’s estimate of fair market rental rates at the acquisition date and are measured over a period equal to the remaining term of the lease for above-market leases and the remaining term of the lease, plus the term of any below-market fixed-rate renewal option periods, if applicable, for below market leases. Intangible lease assets, above-market lease assets, and below-market lease liabilities are collectively referred to as “intangible lease assets and liabilities.” Properties that are probable to be sold are to be designated as “held for sale” on the balance sheet when certain criteria are met. If any debt is assumed in an acquisition, the difference between the fair value and the face value of debt is recorded as a premium or discount and amortized to interest expense over the life of the debt assumed. During the years ended December 31, 2018 and 2017, there was no debt assumed in connection with acquisitions. Beginning January 1, 2017, transaction costs associated with the acquisition of a property (including the acquisition fees paid to the Advisor and its affiliates) are capitalized as incurred in an asset acquisition and are allocated to land, building, and intangible lease assets on a relative fair value basis. Prior to January 1, 2017, costs associated with the acquisition of a property (including acquisition fees paid to the Advisor and its affiliates) were expensed as incurred. For the years ended December 31, 2018 and 2017, $1.2 million and $7.9 million , respectively, of acquisition costs (including the acquisition fees paid to the Advisor and its affiliates) were capitalized in net investment in real estate properties on the consolidated balance sheets instead of expensed as in prior periods. The results of operations for acquired properties are included in the consolidated statements of operations from their respective acquisition dates. Intangible lease assets are amortized to real estate-related depreciation and amortization over the remaining lease term. Above-market lease assets are amortized as a reduction in rental revenues over the remaining lease term and below-market lease liabilities are amortized as an increase in rental revenues over the remaining lease term, plus any applicable fixed-rate renewal option periods. The Company expenses any unamortized intangible lease asset or records an adjustment to rental revenue for any unamortized above-market lease asset or below-market lease liability when a customer terminates a lease before the stated lease expiration date. Land, building, building and land improvements, tenant improvements, lease commissions, and intangible lease assets and liabilities, which are collectively referred to as “real estate assets,” are stated at historical cost less accumulated depreciation and amortization. Costs associated with the development and improvement of the Company’s real estate assets are capitalized as incurred. These costs include capitalized interest and development acquisition fees. Other than the transaction costs associated with the acquisition of a property described above, the Company does not capitalize any other costs, such as taxes, salaries or other general and administrative expenses. See “Capitalized Interest” below for additional detail. Costs incurred in making repairs and maintaining real estate assets are expensed as incurred. Real estate-related depreciation and amortization are computed on a straight-line basis over the estimated useful lives as described in the following table: Land Not depreciated Building 20 to 40 years Building and land improvements 5 to 20 years Tenant improvements Lesser of useful life or lease term Lease commissions Over lease term Intangible lease assets Over lease term Above-market lease assets Over lease term Below-market lease liabilities Over lease term, including below-market fixed-rate renewal options Real estate assets that are determined to be held and used will be reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable, and the Company will evaluate the recoverability of such real estate assets based on estimated future cash flows and the estimated liquidation value of such real estate assets, and provide for impairment if such undiscounted cash flows are insufficient to recover the carrying amount of the real estate asset. If impaired, the real estate asset will be written down to its estimated fair value.
Investment in Unconsolidated Joint Venture	Investment in Unconsolidated Joint Venture Partnerships The Company analyzes its investments under GAAP guidance to determine if any joint venture partnership is a variable interest entity (“VIE”) and whether the requisite substantial participating rights described in the GAAP guidance are held by the partners not affiliated with the Company. If a joint venture partnership is not a VIE and the partners hold substantial participating rights, the Company accounts for its investment in the joint venture partnership under the equity method. Under the equity method, the investment is initially recorded at cost and subsequently adjusted to reflect the Company’s proportionate share of equity in the joint venture partnership’s income (loss) and distributions, which is included in investment in unconsolidated joint venture partnership on its consolidated balance sheets. The Company additionally recognizes its proportionate share of the ongoing income or loss of the unconsolidated joint venture partnership in equity in loss of unconsolidated joint venture partnership on the consolidated statements of operations. The Company evaluates its investments in the unconsolidated joint venture partnerships for impairment whenever events or changes in circumstances indicate that there may be an other-than-temporary decline in value. To do so, the Company calculates the estimated fair value of the investment using various valuation techniques, including, but not limited to, discounted cash flow models, the Company’s intent and ability to retain its investment in the entity, the financial condition and long-term prospects of the entity, and the expected term of the investment. If the Company determined any decline in value is other-than-temporary, the Company would recognize an impairment charge to reduce the carrying value of its investment to fair value.
Cash and Cash Equivalents	Cash and Cash Equivalents Cash and cash equivalents consist of cash on hand and highly liquid investments with original maturities at the acquisition date of three months or less.
Straight-line Rent and Tenant Receivables	Straight-line Rent and Tenant Receivables Straight-line rent and tenant receivables include all straight-line rent and accounts receivable, net of allowances. The Company maintains an allowance for estimated losses that may result from the inability of certain of its customers to make required payments. If a customer fails to make contractual payments beyond any allowance, the Company may recognize additional bad debt expense in future periods equal to the net outstanding balances.
Derivative Instruments	Derivative Instruments The Company records its derivative instruments in the consolidated balance sheets at fair value. The Company’s derivative instruments are designated as cash flow hedges and are used to hedge exposure to variability in expected future cash flows, such as future interest payments. For cash flow hedges, the changes in fair value of the derivative instrument that represent changes in expected future cash flows, which are effectively hedged by the derivative instrument, are initially reported as other comprehensive income in the consolidated statements of equity until the derivative instrument is settled. Upon settlement, the effective portion of the hedge is recognized as other comprehensive income and amortized over the term of the designated cash flow or transaction the derivative instrument was intended to hedge. As such, the effective portion of the hedge impacts net income in the same period as the hedged item. The change in value of any derivative instrument that is deemed to be ineffective is charged directly to net income when the determination of hedge ineffectiveness is made. For purposes of determining hedge ineffectiveness, management estimates the timing and potential amount of future interest payments in order to estimate the cash flows of the designated hedged item or transaction. The Company does not use derivative instruments for trading or speculative purposes.
Debt Issuance Costs	Debt Issuance Costs Debt issuance costs include fees and costs incurred to obtain long-term financing. These fees and costs are amortized to interest expense over the terms of the related credit facilities. Unamortized debt issuance costs are written off if debt is retired before its maturity date.
Capitalized Interest	Capitalized Interest The Company capitalizes interest as a cost of development. Capitalization of interest for a particular asset begins when activities necessary to get the asset ready for its intended use are in progress and when interest costs have been incurred. Capitalization of interest ceases when the project is substantially complete and ready for occupancy.
Distribution Fees	Distribution Fees Distribution fees are paid monthly. Distribution fees are accrued upon the issuance of Class T shares. The Company accrues for: (i) the monthly amount payable as of the balance sheet date, and (ii) the estimated amount of distribution fees to be paid in future periods based on the Class T shares outstanding as of the balance sheet date. The accrued distribution fees are reflected in additional paid-in capital in stockholders’ equity. See “ Note 12 ” for additional information regarding when distribution fees become payable.
Noncontrolling Interests	Noncontrolling Interests Due to the Company’s control of the Operating Partnership through its sole general partner interest and its limited partner interest, the Company consolidates the Operating Partnership. The limited partner interests not owned by the Company are presented as noncontrolling interests in the consolidated financial statements. The noncontrolling interests are reported on the consolidated balance sheets within permanent equity, separate from stockholders’ equity. As the limited partner interests do not participate in the profits and losses of the Operating Partnership, there is no net income or loss attributable to the noncontrolling interests on the consolidated statements of operations. Noncontrolling interests also represent the portion of equity in the acquired subsidiary real estate investment trusts (“Subsidiary REITs”), that the Company does not own. Such noncontrolling interests are equity instruments presented in the consolidated balance sheets as noncontrolling interests within permanent equity. See “ Note 11 ” for additional information regarding the Subsidiary REITs.
Revenue Recognition	Revenue Recognition The Company records rental revenue on a straight-line basis over the full lease term. Certain properties have leases that offer the tenant a period of time where no rent is due or where rent payments change during the term of the lease. Accordingly, the Company records receivables from tenants for rent that the Company expects to collect over the remaining lease term rather than currently, which are recorded as a straight-line rent receivable. When the Company acquires a property, the term of each existing lease is considered to commence as of the acquisition date for purposes of this calculation. Tenant reimbursement revenue includes payments and amounts due from tenants pursuant to their leases for real estate taxes, insurance and other recoverable property operating expenses and is recognized as rental revenue in the period the applicable expenses are incurred. For the years ended December 31, 2018 , 2017 and 2016 , tenant reimbursement revenue recognized in rental revenues was approximately $58.8 million , $52.9 million and $41.4 million , respectively. In connection with property acquisitions, the Company may acquire leases with rental rates above or below estimated market rental rates. Above-market lease assets are amortized as a reduction to rental revenue over the remaining lease term, and below-market lease liabilities are amortized as an increase to rental revenue over the remaining lease term, plus any applicable fixed-rate renewal option periods. The Company expenses any unamortized intangible lease asset or records an adjustment to rental revenue for any unamortized above-market lease asset or below-market lease liability by reassessing the estimated remaining useful life of such intangible lease asset or liability when it becomes probable a customer will terminate a lease before the stated lease expiration date. Upon the disposition of an asset, the Company will evaluate the transaction to determine if control of the asset, as well as other specified criteria, has been transferred to the buyer to determine proper timing of recognizing gains or losses.
Organization and Offering Expenses	Organization and Offering Expenses Organization and offering expenses are accrued by the Company only to the extent that the Company is successful in raising gross offering proceeds. If the Company does not raise additional equity proceeds, no additional amounts will be payable by the Company to the Advisor for reimbursement of cumulative organization and offering expenses. Organization costs are expensed in the period they become reimbursable and offering expenses associated with the Company’s public offerings are recorded as a reduction of gross offering proceeds in additional paid-in capital. See “ Note 12 ” for additional information regarding when organization and offering expenses become reimbursable.
Income Taxes	Income Taxes The Company currently operates as a REIT under the Internal Revenue Code of 1986, as amended, for federal income tax purposes, and elected to be treated as a REIT beginning with its taxable year ended December 31, 2013. As a REIT, the Company generally is not subject to federal income taxes on net income it distributes to its stockholders. The Company intends to make timely distributions sufficient to satisfy the annual distribution requirements. If the Company fails to qualify as a REIT in any taxable year, the Company will be subject to federal income tax on its taxable income at regular corporate tax rates. Even if the Company qualifies for taxation as a REIT, the Company may be subject to certain state and local taxes on its income and property and federal income and excise taxes on its undistributed income.
Net Loss Per Common Share	Net Loss Per Common Share The Company computes net loss per common share by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period for each class.
Fair Value	Fair Value Measurements Fair value measurements are determined based on the assumptions that market participants would use in pricing the asset or liability. Fair value measurements are categorized into one of three levels of the fair value hierarchy based on the lowest level of significant input used. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is 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. Considerable judgment and a high degree of subjectivity are involved in developing these estimates. These estimates may differ from the actual amounts that the Company could realize upon settlement. The fair value hierarchy is as follows: Level 1—Quoted (unadjusted) prices in active markets for identical assets or liabilities. Level 2—Other observable inputs, either directly or indirectly, other than quoted prices included in Level 1, including: • Quoted prices for similar assets/liabilities in active markets; • Quoted prices for identical or similar assets/liabilities in non-active markets (e.g., few transactions, limited information, non-current prices, high variability over time); • Inputs other than quoted prices that are observable for the asset/liability (e.g., interest rates, yield curves, volatilities, default rates); and • Inputs that are derived principally from or corroborated by other observable market data. Level 3—Unobservable inputs that cannot be corroborated by observable market data.
Recently Adopted Accounting Standards and Recently Issued Accounting Standards	Recently Adopted Accounting Standards In May 2014, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2014-09, “Revenue from Contracts with Customers (Topic 606)” (“ASU 2014-09”), which provides guidance for revenue recognition and supersedes the revenue recognition requirements in Topic 605, “Revenue Recognition.” The standard is based on the principle that a company will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services. The guidance specifically excludes revenue derived from lease contracts from its scope. ASU 2014-09 also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. The Company adopted the standard when it became effective for the Company, as of the reporting period beginning January 1, 2018. The Company elected the package of practical expedients, and accordingly did not reallocate contract consideration to lease components within the scope of the existing lease guidance when it adopted ASU 2014-09. Effective January 1, 2018, the Company also adopted ASU No. 2017-05, “Clarifying the Scope of Asset Derecognition Guidance and Accounting for Partial Sales of Nonfinancial Assets” (ASU 2017-05). Through the evaluation and implementation process, the Company has determined the key revenue stream that could be impacted by ASU 2014-09, as amended by ASU 2017-05, is the gain on disposition of real estate reported on the consolidated statements of operation. The Company previously recognized revenue from asset sales upon transfer of title at the time of closing. After adoption of ASU 2014-09, the Company will evaluate the transaction to determine if control of the asset, as well as other specified criteria, has been transferred to the buyer to determine property timing of revenue recognition, as well as transaction price allocation. The adoption of ASU 2014-09 did not have a significant impact on the Company’s consolidated financial statements. In January 2016, the FASB issued ASU No. 2016-01, “Financial Instruments—Overall (Subtopic 825-10): Recognition and Measurement of Financial Assets and Financial Liabilities” (“ASU 2016-01”), which requires: (i) all equity investments to be measured at fair value with changes in fair value recognized in net income; (ii) requires an entity to present separately in other comprehensive income the portion of the total change in the fair value of a liability resulting from a change in the instrument-specific credit risk when the entity has elected to measure the liability at fair value in accordance with the fair value option for financial instruments; and (iii) eliminates the requirement for public entities to disclose the methods and significant assumptions used to estimate the fair value that is required to be disclosed for financial instruments measured at amortized cost on the balance sheet. Early adoption is permitted for the accounting guidance on financial liabilities under the fair value option. The Company adopted this guidance effective January 1, 2018. The adoption of this guidance did not have a significant impact on the Company’s consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, “Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement” (“ASU 2018-13”), which modifies the disclosure requirements on fair value measurements by removing, modifying, or adding certain disclosures. Certain disclosures in ASU 2018-13 are required to be applied on a retrospective basis and others on a prospective basis. The Company adopted this guidance effective September 30, 2018. The adoption of ASU 2018-13 did not have a significant impact on the Company’s consolidated financial statements. Recently Issued Accounting Standards In February 2016, the FASB issued ASU No. 2016-02, “Leases (Subtopic 842)” (“ASU 2016-02”), which provides guidance for greater transparency in financial reporting by organizations that lease assets such as real estate, airplanes and manufacturing equipment by requiring such organizations to recognize lease assets and lease liabilities on the balance sheet and disclosing key information about leasing arrangements. The accounting for lessors will remain largely unchanged from current GAAP; however, the standard requires that lessors expense, on an as-incurred basis, certain initial direct costs that are not incremental in negotiating a lease. Under existing standards, certain of these costs are capitalizable and therefore this new standard will result in certain of these costs being expensed as incurred after adoption. ASU 2016-02 is effective for annual and interim reporting periods beginning after December 15, 2018, with early adoption permitted. The Company adopted the standard when it became effective for the Company, as of the reporting period beginning January 1, 2019, and the Company elected the practical expedients available for implementation under the standard. Under the practical expedients election, the Company would not be required to reassess: (i) whether an expired or existing contract meets the definition of a lease; (ii) the lease classification at the adoption date for expired or existing leases; and (iii) whether costs previously capitalized as initial direct costs would continue to be amortized. The standard also will require new disclosures within the notes accompanying the consolidated financial statements. Additionally, in January 2018, the FASB issued ASU No. 2018-01, “Leases (Subtopic 842): Land Easement Practical Expedient for Transition to Topic 842” (“ASU 2018-01”), which updates ASU 2016-02 to include land easements under the updated guidance, including the option to elect the practical expedient discussed above. The Company also adopted ASU 2018-01 when it became effective for the Company, as of the reporting period beginning January 1, 2019, and the Company elected the practical expedients available for implementation under the standard. In addition, in December 2018, the FASB issued ASU No. 2018-20, “Narrow—Scope Improvements for Lessors” (“ASU 2018-20”), which updates 2016-02 by providing the option to elect a practical expedient for lessors to exclude sales and other similar taxes from the transaction price of the contract, requires lessors to exclude from revenue and expense lessor costs paid directly to a third party by lessees, and clarifies lessors’ accounting for variable payments related to both lease and nonlease components. The Company adopted ASU 2018-20 when it became effective for the Company, as of the reporting period beginning January 1, 2019, and the Company elected the practical expedients available for implementation under the standard. The adoption of these standards did not have a material effect on the Company’s consolidated financial statements. In August 2017, the FASB issued ASU 2017-12, “Derivatives and Hedging: Targeted Improvements to Accounting for Hedging Activities.” The purpose of this updated guidance is to better align a company’s financial reporting for hedging activities with the economic objectives of those activities. The transition guidance provides companies with the option of early adopting the new standard using a modified retrospective transition method in any interim period after issuance of the update, or alternatively requires adoption for fiscal years beginning after December 15, 2018. This adoption method will require the Company to recognize the cumulative effect of initially applying the ASU as an adjustment to accumulated other comprehensive income with a corresponding adjustment to the opening balance of retained earnings as of the beginning of the fiscal year that an entity adopts the update. Based on the Company’s analysis, the adoption of ASU 2017-12 will not have a material effect on its consolidated financial statements.
