Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization	Organization First Industrial Realty Trust, Inc. (the "Company") is a self-administered and fully integrated real estate company which owns, manages, acquires, sells, develops and redevelops industrial real estate. The Company is a Maryland corporation organized on August 10, 1993 and a real estate investment trust ("REIT") as defined in the Internal Revenue Code of 1986 (the "Code"). Unless stated otherwise or the context otherwise requires, the terms "we," "our" and "us" refer to the Company and its subsidiaries, including its operating partnership, First Industrial, L.P. (the "Operating Partnership"), and its consolidated subsidiaries. We began operations on July 1, 1994. The Company's operations are conducted primarily through the Operating Partnership, of which the Company is the sole general partner (the "General Partner"), with an approximate 98.1% ownership interest ("General Partner Units") at September 30, 2019. The Operating Partnership also conducts operations through eight other limited partnerships (the "Other Real Estate Partnerships"), numerous limited liability companies ("LLCs") and certain taxable REIT subsidiaries ("TRSs"), the operating data of which, together with that of the Operating Partnership, is consolidated with that of the Company as presented herein. The Operating Partnership holds at least a 99% limited partnership interest in each of the Other Real Estate Partnerships. The general partners of the Other Real Estate Partnerships are separate corporations, wholly-owned by the Company, each with at least a .01% general partnership interest in the Other Real Estate Partnerships. The Company does not have any significant assets or liabilities other than its investment in the Operating Partnership and its 100% ownership interest in the general partners of the Other Real Estate Partnerships. The Company's noncontrolling interest in the Operating Partnership of approximately 1.9% at September 30, 2019 represents the aggregate partnership interest held by the limited partners thereof ("Limited Partner Units" and together with the General Partner Units, the "Units"). The limited partners of the Operating Partnership are persons or entities who contributed their direct or indirect interests in properties to the Operating Partnership in exchange for common Limited Partner Units of the Operating Partnership and/or recipients of LTIP Units of the Operating Partnership pursuant to the Company's stock incentive plan. See Note 9 for more information. We also own a 49% equity interest in, and provide various services to, a joint venture (the "Joint Venture") through a wholly- owned TRS of the Operating Partnership. The Joint Venture is accounted for under the equity method of accounting. The operating data of the Joint Venture is not consolidated with that of the Company or the Operating Partnership as presented herein. See Note 5 for more information related to the Joint Venture. Profits, losses and distributions of the Operating Partnership, the LLCs, the Other Real Estate Partnerships, the TRSs and the Joint Venture are allocated to the general partner and the limited partners, the members or the shareholders, as applicable, of such entities in accordance with the provisions contained within their respective organizational documents. As of September 30, 2019, we owned 459 industrial properties located in 21 states, containing an aggregate of approximately 62.7 million square feet of gross leasable area ("GLA"). Of the 459 properties owned on a consolidated basis, none of them are directly owned by the Company.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the accounting policies described in the consolidated financial statements and related notes included in our annual report on Form 10-K for the year ended December 31, 2018 ("2018 Form 10-K") and should be read in conjunction with such consolidated financial statements and related notes. The 2018 year end consolidated balance sheet data included in this Form 10-Q filing was derived from the audited consolidated financial statements in our 2018 Form 10-K, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). The following notes to these interim consolidated financial statements highlight significant changes to the notes included in the December 31, 2018 audited consolidated financial statements included in our 2018 Form 10-K and present interim disclosures as required by the Securities and Exchange Commission. Use of Estimates In order to conform with GAAP, in preparation of our consolidated financial statements we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of September 30, 2019 and December 31, 2018, and the reported amounts of revenues and expenses for the three and nine months ended September 30, 2019 and 2018. Actual results could differ from those estimates. In our opinion, the accompanying unaudited interim consolidated financial statements reflect all adjustments necessary for a fair statement of our financial position as of September 30, 2019 and December 31, 2018, the results of our operations and comprehensive income for each of the three and nine months ended September 30, 2019 and 2018, and our cash flows for each of the nine months ended September 30, 2019 and 2018. All adjustments are of a normal recurring nature. Reclassifications We adopted Financial Accounting Standards Board ("FASB") Accounting Standards Codification 842 Leases effective January 1, 2019. Upon adoption of the new standard, tenant recovery revenue and fee revenue collected for delinquent lease payments for 2018 has been reclassified to the Lease Revenue line item in the Consolidated Statements of Operations to conform to the 2019 financial statement presentation. This reclassification had no impact to the 2018 results of operations. Recent Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) ("ASU 2016-02"), which amended the existing accounting standards for lease accounting to increase transparency and comparability among organizations by requiring the recognition of right-of-use assets and lease liabilities on the balance sheet. We adopted the standard effective January 1, 2019 and have elected to use January 1, 2019 as our date of initial application. Consequently, financial information will not be updated and disclosures required under the new standard will not be provided for periods presented before January 1, 2019 as these prior periods conform to the Accounting Standards Codification 840. We elected the package of practical expedients permitted under the transition guidance within the new standard. By adopting these practical expedients, we were not required to reassess (1) whether an existing contract meets the definition of a lease; (2) the lease classification for existing leases; or (3) costs previously capitalized as initial direct costs. As a lessor, our rental revenue remained mainly consistent with previous guidance, apart from the narrower definition of initial direct costs that can be capitalized. The new standard defines initial direct costs as only the incremental costs of signing a lease. As such, certain compensation and certain external legal fees related to the execution of successful lease agreements no longer meet the definition of initial direct costs under the new standard and will be accounted for in the line item General and Administrative Expense . However, the adoption of the standard, along with the adoption of ASU No. 2018-11, Leases - Targeted Improvements which the FASB issued in July 2018, did change our presentation of our results from operations in the Consolidated Statements of Operations . The main changes caused by the adoption of the standards are: • The new standard provided a practical expedient, which allows lessors to combine non-lease components with the related lease components if both the timing and pattern of transfer are the same for the non-lease components(s) and the related lease component, and the lease component would be classified as an operating lease. Lessors are permitted to apply the practical expedient to all existing leases on a retrospective or prospective basis. We elected the practical expedient to combine our lease and non-lease components that meet the defined criteria. The non-lease components of our leases primarily consist of common area maintenance reimbursements from our tenants. • The new standard also requires lessors to exclude from variable payments certain lessor costs, such as real estate taxes, that the lessor contractually requires the lessee to pay directly to a third party on its behalf. Several of our leases require tenants to pay real estate taxes directly to taxing authorities. For periods prior to January 1, 2019, we recorded these payments in the line item Property Expenses with an offset in the line item Lease Revenue. For the three and nine months ended September 30, 2018, $1,796 and $5,544 of these payments are included in the aforementioned line items. • The new standard requires our expected credit loss related to the collectability of lease receivables to be reflected as an adjustment to the line item Lease Revenue . For the three and nine months ended September 30, 2018, the credit loss related to the collectibility of lease receivables was recognized in the line item Property Expenses and was not significant. We are a lessee on a limited number of ground and office leases. Under the new standard, the expense pattern for these leases is generally consistent with that of our historical recognition; however, we are required to record right-of-use assets and lease liabilities on our Consolidated Balance Sheets . Operating lease right-of-use assets and liabilities are recognized at commencement of the lease based on the present value of the lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on information available at lease commencement to determine the present value of lease payments. For leases that commenced prior to the effective date of the standard, we recognized right-of-use assets and lease liabilities based on the present value of remaining lease payments and the incremental borrowing rate on the date of adoption. We have elected the short term lease exemption for certain qualifying leases with lease terms of twelve months or less and, accordingly, did not record right-of-use assets and lease liabilities. We have also elected the practical expedient to not separate lease and non-lease components. For additional disclosures related to leases, refer to Note 13. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeting Improvements to Accounting for Hedging Activities" ("ASU 2017-12"). ASU 2017-12 is intended to better align financial reporting for hedging activities with the economic objectives of those activities. We adopted ASU 2017-02 effective January 1, 2019, and the adoption did not impact our financial condition or results of operations.

Real Estate [Abstract]
Investment in Real Estate	Investment in Real Estate Acquisitions During the nine months ended September 30, 2019, we acquired eight industrial properties comprised of approximately 0.5 million square feet of GLA and eight land parcels, one of which was acquired from our Joint Venture (see Note 5). We accounted for the properties and land parcels as asset acquisitions and therefore capitalized transaction costs to the basis of the acquired assets. The following table summarizes the amounts recognized for each major asset class for the industrial properties and land parcels acquired during the nine months ended September 30, 2019: Land $ 60,352 Building and Improvements 40,481 In-Place Leases 3,419 Below Market Leases (656 ) Other Assets (leasing commissions) 431 Total Purchase Price $ 104,027 The revenue and net income associated with the acquisition of the industrial properties and land parcels, since their respective acquisition dates, are not significant for the nine months ended September 30, 2019. Real Estate Held for Sale As of September 30, 2019, we had one industrial property comprised of approximately 0.04 million square feet of GLA held for sale. Sales During the nine months ended September 30, 2019, we sold ten industrial properties comprised of approximately 1.7 million square feet of GLA. Gross proceeds from the sales were $106,127 . The gain on sale of real estate attributable to these sales was $44,772 . During the three and nine months ended September 30, 2019, we recognized a gain on sale of $8,606 related to the reclassification of a lease from an operating lease to a sales-type lease. See Note 13 for additional information.

See Note 10. (B) The maturity date may be extended an additional year at our election, subject to certain restrictions. Amounts exclude unamortized debt issuance costs of $2,613 and $3,554 as of September 30, 2019 and December 31, 2018, respectively, which are included in the line item Prepaid Expenses and Other Assets, Net . Mortgage Loans Payable, Net During the nine months ended September 30, 2019, we paid off mortgage loans in the aggregate amount of $111,761 . As of September 30, 2019, mortgage loans payable are collateralized, and in some instances cross-collateralized, by industrial properties with a net carrying value of $280,649 . We believe the Operating Partnership and the Company were in compliance with all covenants relating to mortgage loans as of September 30, 2019. Senior Unsecured Notes, Net During the nine months ended September 30, 2019, the Operating Partnership issued $150,000 of 3.97% Series E Guaranteed Senior Notes due July 23, 2029 (the "2029 II Private Placement Notes") (together with the 2027 Private Placement Notes, the 2028 Private Placement Notes, the 2029 Private Placement Notes and the 2030 Private Placement Notes (each as described within this footnote), collectively, the "Private Placement Notes") in a private placement pursuant to a Note and Guaranty Agreement dated May 16, 2019. The 2029 II Private Placement Notes are unsecured obligations of the Operating Partnership that are fully and unconditionally guaranteed by the Company and require semi-annual interest payments. Indebtedness The following is a schedule of the stated maturities and scheduled principal payments of our indebtedness, exclusive of premiums, discounts and debt issuance costs, for the next five years as of September 30, and thereafter: Amount Remainder of 2019 $ 2,480 2020 19,648 2021 345,113 2022 341,552 2023 321 Thereafter 708,549 Total $ 1,417,663 Our unsecured credit facility (the "Unsecured Credit Facility"), our unsecured term loans (the "Unsecured Term Loans"), our Private Placement Notes and the indentures governing our senior unsecured notes contain certain financial covenants, including limitations on incurrence of debt and debt service coverage. Under the Unsecured Credit Facility and the Unsecured Term Loans an event of default can occur if the lenders, in their good faith judgment, determine that a material adverse change has occurred which could prevent timely repayment or materially impair our ability to perform our obligations under the loan agreements. We believe the Operating Partnership and the Company were in compliance with all covenants relating to the Unsecured Credit Facility, the Unsecured Term Loans, the Private Placement Notes and the indentures governing our senior unsecured notes as of September 30, 2019. However, these financial covenants are complex and there can be no assurance that these provisions would not be interpreted by our lenders and noteholders in a manner that could impose and cause us to incur material costs. Fair Value At September 30, 2019 and December 31, 2018, the fair value of our indebtedness was as follows: September 30, 2019 December 31, 2018 Carrying Amount (A) Fair Value Carrying Amount (A) Fair Value Mortgage Loans Payable, Net $ 181,092 $ 193,453 $ 297,716 $ 304,508 Senior Unsecured Notes, Net 698,498 760,282 548,494 546,607 Unsecured Term Loans 460,000 461,005 460,000 461,317 Unsecured Credit Facility 78,000 78,079 — — Total $ 1,417,590 $ 1,492,819 $ 1,306,210 $ 1,312,432 _______________ (A) The carrying amounts include unamortized premiums and discounts and exclude unamortized debt issuance costs. The fair values of our mortgage loans payable were determined by discounting the future cash flows using the current rates at which similar loans would be made based upon similar remaining maturities. The current market rates we utilized were internally estimated. The fair value of the senior unsecured notes were determined by using rates, as advised by our bankers, that are based upon recent trades within the same series of the senior unsecured notes, recent trades for senior unsecured notes with comparable maturities, recent trades for fixed rate unsecured notes from companies with profiles similar to ours, as well as overall economic conditions. The fair value of the Unsecured Credit Facility and the Unsecured Term Loans was determined by discounting the future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining term, assuming no repayment until maturity. We have concluded that our determination of fair value for each of our mortgage loans payable, senior unsecured notes, the Unsecured Term Loans and the Unsecured Credit Facility was primarily based upon Level 3 inputs.

Variable Interest Entities [Abstract]
Variable Interest Entities	Variable Interest Entities Other Real Estate Partnerships The Other Real Estate Partnerships are variable interest entities ("VIEs") of the Operating Partnership and the Operating Partnership is the primary beneficiary, thus causing the Other Real Estate Partnerships to be consolidated by the Operating Partnership. In addition, the Operating Partnership is a VIE of the Company and the Company is the primary beneficiary. The following table summarizes the assets and liabilities of the Other Real Estate Partnerships included in our consolidated balance sheets, net of intercompany amounts: September 30, 2019 December 31, 2018 ASSETS Assets: Net Investment in Real Estate $ 257,318 $ 260,528 Other Assets, Net 37,870 25,059 Total Assets $ 295,188 $ 285,587 LIABILITIES AND PARTNERS' CAPITAL Liabilities: Mortgage Loans Payable, Net $ 11,089 $ 20,497 Other Liabilities, Net 21,423 9,045 Partners' Capital 262,676 256,045 Total Liabilities and Partners' Capital $ 295,188 $ 285,587 Joint Venture During the second quarter 2018, we entered into the Joint Venture with a third party partner for the purpose of developing, leasing, operating and potentially selling approximately 532 net developable acres of land located in the Phoenix, Arizona metropolitan area. The purchase price of the land was $49,000 and was acquired by the Joint Venture via cash equity contributions from us and our joint venture partner. Through a wholly-owned TRS of the Operating Partnership, we own a 49% interest in the Joint Venture. During the nine months ended September 30, 2019, the Joint Venture sold three land parcels, totaling 236 net developable acres, for gross proceeds of $57,178 and a total gain on sale of real estate of $30,236 . Our economic share of the gain on sale is $14,816 . However, we were the purchaser of one of the land parcels, acquiring 39 net developable acres from the Joint Venture. Accordingly, we netted our gain on sale pertaining to that sale in the amount of $3,121 against the basis of the land acquired. During the nine months ended September 30, 2018, the Joint Venture sold one land parcel, totaling 21 net developable acres, for gross proceeds of $3,973 and total gain on sale of real estate of $181 . Net income of the Joint Venture for the nine months ended September 30, 2019 was $30,029 . Net loss of the Joint Venture for the nine months ended September 30, 2018 was $196 . Under the Joint Venture's operating agreement, we act as the managing member of the Joint Venture and are entitled to receive fees for providing management, leasing, development, construction supervision, disposition and asset management services to the Joint Venture. In addition, the Joint Venture's operating agreement provides us the ability to earn an incentive fee based on the ultimate financial performance of the Joint Venture. In accordance with GAAP, for the nine months ended September 30, 2019, we calculated the incentive fee using a hypothetical liquidation basis assuming the remaining net assets of the Joint Venture were distributed at book value. Under this hypothetical liquidation methodology, we recognized an incentive fee of approximately $4,900 , which is recorded in the Equity In Income of Joint Venture line item in the statement of operations and as an increase to the Investment in Joint Venture line item on the balance sheet. Any incentive fee earned will be calculated based on the final economic performance of the Joint Venture and will be paid towards the end of the Joint Venture's life. During the nine months ended September 30, 2019, we recognized fees of $88 from the Joint Venture related to asset management and development services we provided to the Joint Venture. At September 30, 2019, we had a receivable from the Joint Venture of $43 related to these asset management and development fees. As part of our assessment of the appropriate accounting treatment for the Joint Venture, we reviewed the operating agreement of the Joint Venture in order to determine our rights and the rights of our joint venture partner, including whether those rights are protective or participating. We found that the operating agreement contains certain protective rights, such as the requirement of both member's approval to sell, finance or refinance the property and to pay capital expenditures and operating expenditures outside of the approved budget. However, we also found that we and our Joint Venture partner jointly (i) approve the annual budget, (ii) approve certain expenditures, (iii) review and approve the Joint Venture's tax return before filing and (iv) approve each lease at a developed property. We consider the latter rights substantive participation rights that result in shared, joint power over the activities that most significantly impact the performance of the Joint Venture. As such, we concluded to account for our investment in the Joint Venture under the equity method of accounting.

Long-Term Compensation

Long-Term Compensation	9 Months Ended

Share-based Payment Arrangement, Noncash Expense [Abstract]
Long-Term Compensation	Awards of LTIP Units During 2018, the Company modified its stock incentive program to allow for the granting of awards to certain officers, certain employees and directors in the form of LTIP units ("LTIP Units"). An LTIP Unit is a class of limited partnership interest of the Operating Partnership that is structured as a “profits interest” for U.S. federal income tax purposes. Generally, LTIP Units entitle the holder to receive distributions from the Operating Partnership that are equivalent to the dividends and distributions that would be made with respect to the number of shares of Common Stock underlying such LTIP Units, though receipt of such distributions may be delayed or made contingent on vesting. Once an LTIP Unit has vested and received allocations of book income sufficient to increase the book capital account balance associated with such LTIP Unit (which will initially be zero) to equal, on a per-unit basis, the book capital account balance associated with a “common” Limited Partner Unit of the Operating Partnership, it automatically becomes a common Limited Partner Unit that is convertible by the holder into one share of Common Stock or a cash equivalent, at the Company’s option. Awards with Performance Measures During the nine months ended September 30, 2019, the Company granted 36,064 performance units ("Performance units") and 166,942 LTIP Units, based on performance-based criteria ("Performance LTIP Units" and, together with the Performance units, collectively the "Performance Awards") to certain employees, which had a fair value of $2,527 on the grant date as determined by a lattice-binomial option-pricing model based on a Monte Carlo simulation. The Performance Awards vest based upon the relative total shareholder return ("TSR") of the Company's common stock compared to a weighted average TSR of the MSCI US REIT Index and the NAREIT Industrial Index over a performance period of three years . Compensation expense is charged to earnings over the vesting periods for Performance Awards. At the end of the measuring period, vested Performance units convert into shares of common stock. Service Based Awards For the nine months ended September 30, 2019, the Company awarded 87,606 shares of restricted stock awards and 112,428 of LTIP Units based on service-based criteria ("Service LTIP Units") to certain employees and outside directors, which had an aggregate fair value of $6,727 on the date such awards were approved by the Compensation Committee of the Board of Directors. Both the restricted stock awards and Service LTIP Units granted to employees were based upon the prior achievement of certain corporate performance goals and will vest ratably over a period of three years based on continued employment. Restricted Stock awards and Service LTIP Units granted to outside directors vest after a one year period. The Operating Partnership issued restricted Unit awards to the Company in the same amount for the restricted stock awards. Compensation expense is charged to earnings over the vesting periods for both the restricted stock/restricted Unit awards and the Service LTIP Units. Outstanding Restricted Stock/Restricted Unit Awards, Performance Units and LTIP Units We recognized $2,130 and $2,003 for the three months ended September 30, 2019 and 2018, respectively and $5,945 and $5,689 for the nine months ended September 30, 2019 and 2018 respectively, in compensation expense related to the amortization of restricted stock or restricted Unit awards, Performance units, and LTIP Units. Restricted stock or restricted Unit award, Performance unit and LTIP Unit amortization capitalized in connection with development activities was $243 and $684 for the three and nine months ended September 30, 2019, respectively, and was not significant for the comparable 2018 periods. At September 30, 2019, we had $10,963 in unrecognized compensation related to unvested restricted stock or restricted Unit awards, Performance units and LTIP Units. The weighted average period that the unrecognized compensation is expected to be recognized is 0.93 years.

Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives	Derivatives Our objectives in using derivatives are to add stability to interest expense and to manage our cash flow volatility and exposure to interest rate movements. To accomplish these objectives, we primarily use derivative instruments as part of our interest rate risk management strategy. Derivative instruments designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for fixed-rate payments over the life of the agreements without exchange of the underlying notional amount. Fair Value Hedges During December 2018, in anticipation of issuing long-term debt in the future, we entered into two treasury locks with an aggregate notional value of $100,000 to manage our exposure to changes in the ten-year U.S. Treasury rate (the "2018 Treasury Locks"). During April 2019, we paid $3,149 to settle the 2018 Treasury Locks with our counterparties. The 2018 Treasury Locks fixed the ten-year U.S. Treasury rate at a weighted average of 2.93% . We had designated the 2018 Treasury Locks as cash flow hedges and will amortize the payment made to our counterparties into interest expense over the 10-year period which corresponds to the term of our newly issued private placement debt (see Note 4). In connection with the originations of the Unsecured Term Loans (see Note 4), we entered into interest rate swaps to manage our exposure to changes in the one month LIBOR rate. The four interest rate swaps, which fix the variable rate of the 2014 Unsecured Term Loan, have an aggregate notional value of $200,000 , mature on January 29, 2021 and fix the LIBOR rate at a weighted average rate of 2.29% (the "2014 Swaps"). The six interest rate swaps, which fix the variable rate of the 2015 Unsecured Term Loan, have an aggregate notional value of $260,000 , mature on September 12, 2022 and fix the LIBOR rate at a weighted average rate of 1.79% (the "2015 Swaps"). We designated the 2014 Swaps and 2015 Swaps as cash flow hedges. Our agreements with our derivative counterparties contain provisions where if we default on any of our indebtedness, then we could also be declared in default on our derivative obligations subject to certain thresholds. As of September 30, 2019, we had not posted any collateral related to these agreements and were not in breach of any of the provisions of these agreements. If we had breached these agreements, we could have been required to settle our obligations under the agreements at their termination value. The following table sets forth our financial liabilities related to the 2015 Swaps and the 2014 Swaps, which are included in the line item Accounts Payable, Accrued Expenses and Other Liabilities and are accounted for at fair value on a recurring basis as of September 30, 2019: Fair Value Measurements: Description Fair Value Quoted Prices in Active Markets for Identical Assets (Level 1) Significant Other Observable Inputs (Level 2) Unobservable Inputs (Level 3) Derivatives designated as a hedging instrument: Liabilities: 2014 Swaps $ (1,875 ) — $ (1,875 ) — 2015 Swaps $ (2,804 ) — $ (2,804 ) — There was no ineffectiveness recorded on the 2014 Swaps and the 2015 Swaps during the nine months ended September 30, 2019. See Note 7 for more information regarding our derivatives. The estimated fair value of the 2014 Swaps and the 2015 Swaps was determined using the market standard methodology of netting the discounted fixed cash payments and the discounted expected variable cash receipts. The variable cash receipts are based on an expectation of interest rates (forward curves) derived from observable market interest rate curves. In addition, credit valuation adjustments are incorporated in the fair value to account for potential non-performance risk, including our own non-performance risk and the respective counterparty's non-performance risk. We determined that the significant inputs used to value the 2014 Swaps and the 2015 Swaps fell within Level 2 of the fair value hierarchy.

In our opinion, the liabilities, if any, that may ultimately result from such legal actions are not expected to have a materially adverse effect on our consolidated financial position, operations or liquidity. In conjunction with the development of industrial properties, we have entered into agreements with general contractors for the construction of industrial properties. At September 30, 2019, we had 13 industrial properties totaling approximately 3.3 million square feet of GLA under construction. The estimated total investment as of September 30, 2019 is approximately $270,100 . Of this amount, approximately $110,100 remains to be funded.

Our office leases have remaining lease terms of less than one year to seven years and our ground leases have remaining terms of 35 years to 52 years. For the nine months ended September 30, 2019, we recognized $1,677 of operating lease expense, inclusive of short-term and variable lease costs which are not significant. The following is a schedule of the maturities of operating lease liabilities for the next five years as of September 30, 2019, and thereafter: Remainder of 2019 $ 593 2020 2,321 2021 2,288 2022 2,238 2023 2,068 Thereafter 62,622 Total Lease Payments 72,130 Less Imputed Interest (A) 49,561 Total $ 22,569 (A) Calculated using the discount rate for each lease.

For purposes of determining our lease term, we excluded periods covered by an option since it was not reasonably certain at lease commencement that we would exercise the options. Lessor Disclosures Our properties and certain land parcels are leased to tenants and classified as operating leases. Future minimum rental receipts, excluding variable payments and tenant reimbursements of expenses, under non-cancelable operating leases executed as of September 30, 2019 are approximately as follows: Remainder of 2019 $ 81,674 2020 324,063 2021 288,686 2022 247,374 2023 208,308 Thereafter 591,756 Total $ 1,741,861 Future minimum rental receipts, excluding tenant reimbursements of expenses, under non-cancelable operating leases executed as of December 31, 2018 were approximately as follows: 2019 $ 305,689 2020 288,817 2021 244,743 2022 205,097 2023 169,243 Thereafter 451,151 Total $ 1,664,740 Several of our operating leases include options to extend the lease term and/or to purchase the building. For purposes of determining the lease term and lease classification, we exclude these extension periods and purchase options unless it is reasonably certain at lease commencement that the option will be exercised. During the three months ended September 30, 2019, a tenant exercised its lease option to purchase a 0.6 million square foot building located in our Phoenix market. The option includes a fixed purchase price and an expected closing date in August 2020. At the time the tenant exercised the option, we reassessed the lease classification of this lease and, based on various qualitative factors, we determined that it was reasonably certain the tenant would close on the acquisition of the building. Accordingly, during the three months ended September 30, 2019, we reclassified the lease from an operating lease to a sales-type lease, which resulted in a gain on sale of $8,606 . Additionally, we derecognized the net book value of the property and recorded a lease receivable of $54,521 which represents the discounted present value of the remaining lease payments and the fixed purchase option price. The lease receivable is included in Prepaid and Other Assets, Net on our Consolidated Balance Sheets. See Supplemental Information to the Statements of Cash Flows. Future minimum cash receipts, excluding tenant reimbursements of expenses, for this sales-type lease are $851 for the remainder of 2019 and $56,830

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited interim consolidated financial statements have been prepared in accordance with the accounting policies described in the consolidated financial statements and related notes included in our annual report on Form 10-K for the year ended December 31, 2018 ("2018 Form 10-K") and should be read in conjunction with such consolidated financial statements and related notes. The 2018 year end consolidated balance sheet data included in this Form 10-Q filing was derived from the audited consolidated financial statements in our 2018 Form 10-K, but does not include all disclosures required by accounting principles generally accepted in the United States of America ("GAAP"). The following notes to these interim consolidated financial statements highlight significant changes to the notes included in the December 31, 2018 audited consolidated financial statements included in our 2018 Form 10-K and present interim disclosures as required by the Securities and Exchange Commission.
Use of Estimates	Use of Estimates In order to conform with GAAP, in preparation of our consolidated financial statements we are required to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of September 30, 2019 and December 31, 2018, and the reported amounts of revenues and expenses for the three and nine months ended September 30, 2019 and 2018. Actual results could differ from those estimates. In our opinion, the accompanying unaudited interim consolidated financial statements reflect all adjustments necessary for a fair statement of our financial position as of September 30, 2019 and December 31, 2018, the results of our operations and comprehensive income for each of the three and nine months ended September 30, 2019 and 2018, and our cash flows for each of the nine months ended September 30, 2019 and 2018. All adjustments are of a normal recurring nature.
Reclassifications	Reclassifications We adopted Financial Accounting Standards Board ("FASB") Accounting Standards Codification 842 Leases effective January 1, 2019. Upon adoption of the new standard, tenant recovery revenue and fee revenue collected for delinquent lease payments for 2018 has been reclassified to the Lease Revenue line item in the Consolidated Statements of Operations to conform to the 2019 financial statement presentation. This reclassification had no impact to the 2018 results of operations.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2016, the FASB issued Accounting Standards Update ("ASU") No. 2016-02, Leases (Topic 842) ("ASU 2016-02"), which amended the existing accounting standards for lease accounting to increase transparency and comparability among organizations by requiring the recognition of right-of-use assets and lease liabilities on the balance sheet. We adopted the standard effective January 1, 2019 and have elected to use January 1, 2019 as our date of initial application. Consequently, financial information will not be updated and disclosures required under the new standard will not be provided for periods presented before January 1, 2019 as these prior periods conform to the Accounting Standards Codification 840. We elected the package of practical expedients permitted under the transition guidance within the new standard. By adopting these practical expedients, we were not required to reassess (1) whether an existing contract meets the definition of a lease; (2) the lease classification for existing leases; or (3) costs previously capitalized as initial direct costs. As a lessor, our rental revenue remained mainly consistent with previous guidance, apart from the narrower definition of initial direct costs that can be capitalized. The new standard defines initial direct costs as only the incremental costs of signing a lease. As such, certain compensation and certain external legal fees related to the execution of successful lease agreements no longer meet the definition of initial direct costs under the new standard and will be accounted for in the line item General and Administrative Expense . However, the adoption of the standard, along with the adoption of ASU No. 2018-11, Leases - Targeted Improvements which the FASB issued in July 2018, did change our presentation of our results from operations in the Consolidated Statements of Operations . The main changes caused by the adoption of the standards are: • The new standard provided a practical expedient, which allows lessors to combine non-lease components with the related lease components if both the timing and pattern of transfer are the same for the non-lease components(s) and the related lease component, and the lease component would be classified as an operating lease. Lessors are permitted to apply the practical expedient to all existing leases on a retrospective or prospective basis. We elected the practical expedient to combine our lease and non-lease components that meet the defined criteria. The non-lease components of our leases primarily consist of common area maintenance reimbursements from our tenants. • The new standard also requires lessors to exclude from variable payments certain lessor costs, such as real estate taxes, that the lessor contractually requires the lessee to pay directly to a third party on its behalf. Several of our leases require tenants to pay real estate taxes directly to taxing authorities. For periods prior to January 1, 2019, we recorded these payments in the line item Property Expenses with an offset in the line item Lease Revenue. For the three and nine months ended September 30, 2018, $1,796 and $5,544 of these payments are included in the aforementioned line items. • The new standard requires our expected credit loss related to the collectability of lease receivables to be reflected as an adjustment to the line item Lease Revenue . For the three and nine months ended September 30, 2018, the credit loss related to the collectibility of lease receivables was recognized in the line item Property Expenses and was not significant. We are a lessee on a limited number of ground and office leases. Under the new standard, the expense pattern for these leases is generally consistent with that of our historical recognition; however, we are required to record right-of-use assets and lease liabilities on our Consolidated Balance Sheets . Operating lease right-of-use assets and liabilities are recognized at commencement of the lease based on the present value of the lease payments over the lease term. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on information available at lease commencement to determine the present value of lease payments. For leases that commenced prior to the effective date of the standard, we recognized right-of-use assets and lease liabilities based on the present value of remaining lease payments and the incremental borrowing rate on the date of adoption. We have elected the short term lease exemption for certain qualifying leases with lease terms of twelve months or less and, accordingly, did not record right-of-use assets and lease liabilities. We have also elected the practical expedient to not separate lease and non-lease components. For additional disclosures related to leases, refer to Note 13. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeting Improvements to Accounting for Hedging Activities" ("ASU 2017-12"). ASU 2017-12 is intended to better align financial reporting for hedging activities with the economic objectives of those activities. We adopted ASU 2017-02 effective January 1, 2019, and the adoption did not impact our financial condition or results of operations.
