Accounting Policies [Abstract]
General	NOTE 1. GENERAL Business . Prologis, Inc. (or the “Parent”) commenced operations as a fully integrated real estate company in 1997, elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and believes the current organization and method of operation will enable it to maintain its status as a REIT. The Parent is the general partner of Prologis, L.P. (or the “Operating Partnership” or “OP”). Through the OP, we are engaged in the ownership, acquisition, development and management of logistics facilities with a focus on key markets in 19 countries on four continents. We invest in real estate through wholly owned subsidiaries and other entities through which we co-invest with partners and investors. We maintain a significant level of ownership in these co-investment ventures, which may be consolidated or unconsolidated based on our level of control of the entity. Our current business strategy consists of two operating business segments: Real Estate Operations and Strategic Capital. Our Real Estate Operations segment represents the ownership and development of logistics properties. Our Strategic Capital segment represents the management of unconsolidated co-investment ventures and other ventures. See Note 11 for further discussion of our business segments. Unless otherwise indicated, the Notes to the Consolidated Financial Statements apply to both the Parent and the OP. The terms “the Company,” “Prologis,” “we,” “our” or “us” means the Parent and OP collectively For each share of preferred or common stock the Parent issues, the OP issues a corresponding preferred or common partnership unit, as applicable, to the Parent in exchange for the contribution of the proceeds from the stock issuance. At September 30, 2019, the Parent owned a 97.22% common general partnership interest in the OP and 100% of the preferred units in the OP. The remaining 2.78% common limited partnership interests, which include 8.6 million Class A common limited partnership units (“Class A Units”) in the OP, are owned by unaffiliated investors and certain current and former directors and officers of the Parent. Each partner’s percentage interest in the OP is determined based on the number of OP units held, including the number of OP units into which Class A Units are convertible, compared to total OP units outstanding at each period end and is used as the basis for the allocation of net income or loss to each partner. At the end of each reporting period, a capital adjustment is made in the OP to reflect the appropriate ownership interest for each of the common unitholders. These adjustments are reflected in the line items Reallocation of Equity Reallocation of Capital As the sole general partner of the OP, the Parent has complete responsibility and discretion in the day-to-day management and control of the OP and we operate the Parent and the OP as one enterprise. The management of the Parent consists of the same members as the management of the OP. These members are officers of the Parent and employees of the OP or one of its subsidiaries. As general partner with control of the OP, the Parent is the primary beneficiary and therefore consolidates the OP. Because the Parent’s only significant asset is its investment in the OP, the assets and liabilities of the Parent and the OP are the same on their respective financial statements. Basis of Presentation. The accompanying Consolidated Financial Statements are prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) and are presented in our reporting currency, the U.S. dollar. References herein to the translation of activity for significant nonrecurring transactions are at the rate in effect at the date of the transaction. All material intercompany transactions with consolidated entities have been eliminated. The accompanying unaudited interim financial information has been prepared according to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in our annual financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations. Our management believes that the disclosures presented in these financial statements are adequate to make the information presented not misleading. In our opinion, all adjustments and eliminations, consisting only of normal recurring adjustments, necessary to present fairly the financial position and results of operations for both the Parent and the OP for the reported periods have been included. The results of operations for such interim periods are not necessarily indicative of the results for the full year. The accompanying unaudited interim financial information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2018, as filed with the SEC, and other public information. Reclassifications. Upon adoption of the new lease standard, rental recoveries for 2018 have been reclassified to Rental Revenues in the Consolidated Statements of Income to conform to the 2019 financial statement presentation. New Accounting Pronouncements. New Accounting Standards Adopted Leases. In February 2016, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update (“ASU”) that provided the principles for the recognition, measurement, presentation and disclosure of leases. The guidance amended the existing accounting standards, including the requirement that lessees recognize right-of-use assets and lease liabilities for leases with terms greater than twelve months in the Consolidated Balance Sheets. Additional guidance and targeted improvements to the February 2016 ASU were made through the issuance of supplementary ASUs in July 2018, December 2018 and March 2019. We refer to all four ASUs collectively as the “new lease standard.” We adopted the new lease standard on January 1, 2019 and applied it to leases that were in place on the effective date. Results for reporting periods beginning January 1, 2019 are presented under the new lease standard. We elected the package of practical expedients and were not required to reassess the following upon adoption: (i) whether an expired or existing contract met the definition of a lease; (ii) the lease classification at January 1, 2019 for existing leases; and (iii) whether leasing costs previously capitalized as initial direct costs would continue to be amortized. This allowed us to continue to account for our existing ground and office space leases as operating leases, however, any new or renewed ground leases after January 1, 2019 may be classified as financing leases unless they meet certain conditions to be considered a lease involving land owned by a government unit or authority. Upon adoption, we did not have an adjustment to the opening balance of retained earnings due to the election of these practical expedients. • As a lessor. The new lease standard requires that lessors expense, on an as-incurred basis, certain initial direct costs that are not incremental in negotiating a lease. Initial direct costs include the salaries and related costs for employees directly working on leasing activities. Prior to January 1, 2019, these costs were capitalizable in Other Assets and therefore the new lease standard resulted in certain of these costs being expensed as incurred through Rental Expenses . During the three and nine months ended September 30, 2018, we capitalized $5.2 million and $15.7 million, respectively, of internal costs related to our leasing activities. We will continue to amortize initial direct costs capitalized prior to January 1, 2019. We adopted the practical expedient that allowed us to not separate expenses reimbursed by our customers (“rental recoveries”) from the associated rental revenue if certain criteria were met. We assessed these criteria and concluded that the timing and straight-line pattern of transfer to the lessee for rental revenue and the associated rental recoveries are the same and as our leases qualify as operating leases, we accounted for and presented rental revenue and rental recoveries as a single component under Rental Revenues • As a lessee. At January 1, 2019 we recognized Lease Right-of-Use (“ROU”) Assets and Lease Liabilities , principally for our ground and office space leases, in which we are the lessee. See Note 3 for further disclosure around our adoption of the new lease standard. Derivatives and Hedging . In August 2017, the FASB issued an ASU that simplified the application of hedge accounting guidance in current GAAP and improved the reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its consolidated financial statements. Among the simplification updates, the ASU eliminated the requirement in current GAAP to separately recognize periodic hedge ineffectiveness. Mismatches between the changes in value of the hedged item and hedging instrument may still occur but they will no longer be separately reported. The ASU required the presentation of the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. We adopted the ASU on January 1, 2019 on a modified retrospective basis and there was no adjustment to the opening balance of retained earnings.

Business Combinations [Abstract]
DCT Transaction	NOTE 2. DCT TRANSACTION W e acquired DCT Industrial Trust Inc. and DCT Industrial Operating Partnership LP (collectively “DCT”) on August 22, 2018 (“DCT Transaction”). The DCT Transaction was completed for $8.5 billion through the issuance of equity based on the closing price of Prologis’ common stock on August 21, 2018 and the assumption of debt. In connection with the transaction, each issued and outstanding share or unit held by a DCT stockholder or unitholder was converted automatically into 1.02 shares of Prologis common stock or common units of Prologis, L.P., respectively, including shares and units under DCT’s equity incentive plan that became fully vested at closing. Through the DCT Transaction, we acquired a portfolio of logistics real estate assets that consisted of 408 operating properties, aggregating 68.0 million square feet, 10 properties under development, aggregating 2.8 million square feet and 305 acres of land with build-out potential of 4.5 million square feet. The aggregate equity consideration of approximately $6.6 billion is calculated below (in millions, except price per share): Number of Prologis shares and units issued upon conversion of DCT shares and units at August 21, 2018 99.73 Multiplied by price of Prologis' common stock on August 21, 2018 $ 65.75 Fair value of Prologis shares and units issued $ 6,557 We accounted for the DCT Transaction as an asset acquisition and as a result the transaction costs of $50.0 million were capitalized to the basis of the acquired properties. Transaction costs include investment banker advisory fees, legal fees and other costs. Under acquisition accounting, the total purchase price was allocated to the DCT net tangible and identifiable intangible assets acquired and liabilities assumed based on their relative fair values as follows (in millions): Net investments in real estate $ 8,362 Intangible assets, net of intangible liabilities 292 Cash and other assets 24 Debt (1,863 ) Accounts payable, accrued expenses and other liabilities (143 ) Noncontrolling interests (65 ) Total purchase price, including transaction costs $ 6,607

(“IPT”) for approximately $4.0 billion in a cash transaction, including the assumption and repayment of debt. The transaction, currently expected to close in January 2020, is subject to the approval of IPT stockholders and other customary closing conditions.

Leases As a Lessor We lease our operating properties to customers under agreements that are classified as operating leases. We recognize the total minimum lease payments provided for under the leases on a straight-line basis over the lease term. Generally, under the terms of our leases, the majority of our rental expenses, including common area maintenance, real estate taxes and insurance, are recovered from our customers. We record amounts reimbursed by customers in the period that the applicable expenses are incurred. Rental Revenues The following table summarizes the minimum lease payments due from our customers on leases with lease periods greater than one year for space in our operating properties, prestabilized and under development properties, leases of land subject to ground leases and assets held for sale or contribution at September 30, 2019 (in thousands): 2019 $ 538,879 2020 2,074,883 2021 1,823,249 2022 1,510,617 2023 1,218,684 Thereafter 3,911,733 Total $ 11,078,045 These amounts do not reflect future rental revenue from the renewal or replacement of existing leases and exclude reimbursements of operating expenses and rental increases that are not fixed. As a Lessee We have approximately 130 ground and office space leases, which qualify as operating leases, with remaining lease terms of 1 to 89 years at September 30, 2019. The following table summarizes the fixed, future minimum rental payments, excluding variable costs, which are discounted by our incremental borrowing rates to calculate the lease liabilities of our operating leases in which we are the lessee and for which the lease has commenced (in thousands): September 30, 2019 December 31, 2018 2019 $ 12,565 $ 38,769 2020 46,715 38,267 2021 48,108 34,307 2022 41,314 32,312 2023 35,887 30,180 Thereafter 674,384 670,147 Total undiscounted rental payments 858,973 $ 843,982 Less imputed interest 426,851 Total lease liabilities $ 432,122 The weighted average remaining lease term for our operating leases was 30 and 28 years at September 30, 2019 and December 31, 2018, respectively. We do not include renewal options in the lease term for calculating the lease liability unless we are reasonably certain we will exercise the option, or the lessor has the sole ability to exercise the option. The weighted average incremental borrowing rate was 3.8% at September 30, 2019. We assigned a collateralized interest rate to each lease based on the term of the lease and the currency in which the lease is denominated.

Equity Method Investments And Joint Ventures [Abstract]
Unconsolidated Entities	NOTE 4. UNCONSOLIDATED ENTITIES Summary of Investments We have investments in entities through a variety of ventures. We co-invest in entities that own multiple properties with partners and investors and we provide asset and property management services to these entities, which we refer to as co-investment ventures. These entities may be consolidated or unconsolidated, depending on the structure, our partner’s participation and other rights and our level of control of the entity. This note details our investments in unconsolidated co-investment ventures, which are related parties and are accounted for using the equity method of accounting. See Note 7 for more detail regarding our consolidated investments that are not wholly owned. We also have other ventures, generally with one partner and that we do not manage, which we account for using the equity method. We refer to our investments in all entities accounted for using the equity method, both unconsolidated co-investment ventures and other ventures, collectively, as unconsolidated entities. The following table summarizes our investments in and advances to our unconsolidated entities (in thousands): September 30, December 31, 2019 2018 Unconsolidated co-investment ventures $ 5,528,873 $ 5,407,838 Other ventures 357,947 337,456 Total $ 5,886,820 $ 5,745,294 Unconsolidated Co-Investment Ventures The following table summarizes the Strategic Capital Revenues Three Months Ended September 30, Nine Months Ended September 30, 2019 2018 2019 2018 Recurring fees $ 67,888 $ 58,946 $ 195,542 $ 171,508 Transactional fees 14,094 11,798 41,272 39,250 Promote revenue (1) 148,191 - 155,474 68,218 Total strategic capital revenues from unconsolidated co-investment ventures (2) $ 230,173 $ 70,744 $ 392,288 $ 278,976 (1 ) Includes promote revenue earned from an unconsolidated co-investment venture in Europe in September 2019 and China in March 2018, respectively.

The difference between our ownership interest of a venture’s equity and our investment balance at September 30, 2019 and December 31, 2018, results principally from four types of transactions: (i) deferred gains from the contribution of property to a venture prior to January 1, 2018; (ii) recording additional costs associated with our investment in the venture; (iii) receivables, principally for fees and promotes ($258.0 million and $166.7 million, respectively); and (iv) customer security deposits retained subsequent to property contributions to Nippon Prologis REIT, Inc. ($134.4 million and $122.0 million, respectively) (3) Represents our weighted average ownership interest based on each entity’s contribution of total assets, before depreciation, net of other liabilities. Equity Commitments Related to Certain Unconsolidated Co-Investment Ventures At September 30, 2019, our remaining equity commitments were $457.8 million, principally for Prologis China Logistics Venture and Prologis Targeted U.S. Logistics Fund. The equity commitments expire from 2020 to 2026.

Pricing under the Global Facility, including the spread over LIBOR, facility fees and letter of credit fees, varies based on the public debt ratings of the OP. The Global Facility is scheduled to mature in January 2023; however, we may extend the maturity date for six months on two occasions, subject to the satisfaction of certain conditions and payment of extension fees. We have the ability to increase the Global Facility to $4.5 billion, subject to currency fluctuations and obtaining additional lender commitments. We also have a Japanese yen revolver (the “Revolver”) with availability of ¥50.0 billion ($463.0 million at September 30, 2019). We have the ability to increase the Revolver to ¥65.0 billion ($601.9 million at September 30, 2019), subject to obtaining additional lender commitments. Pricing under the Revolver, including the spread over LIBOR, facility fees and letter of credit fees, varies based on the public debt ratings of the OP. The Revolver is scheduled to mature in February 2021; however, we may extend the maturity date for one year, subject to the satisfaction of certain conditions and payment of extension fees. We refer to the Global Facility and the Revolver, collectively, as our “Credit Facilities.” The following table summarizes information about our Credit Facilities at September 30, 2019 (in millions): Aggregate lender commitments $ 3,920 Less: Borrowings outstanding - Outstanding letters of credit 30 Current availability $ 3,890 Senior Notes In March 2019, we completed a private placement for ¥10.0 billion ($90.5 million) of senior notes with a stated interest rate of 1.2%, maturing in March 2039. In September 2019, we issued three series of senior notes for a total of €1.8 billion ($2.0 billion), bearing a weighted-average fixed interest rate of 0.7% and maturing in September 2027 through 2049. We utilized the proceeds to pay off senior notes of €600.0 million ($656.3 million) bearing an interest rate of 1.4% and maturing in October 2020 and $498.7 million on our multi-currency term loan (the “2017 Term Loan”). We anticipate using the remaining proceeds to repay additional borrowings in the next twelve months and for general corporate purposes. Term Loans In January 2019, we entered into two unsecured Japanese yen term loans for a total of ¥15.0 billion ($137.1 million) that bear interest of Yen LIBOR plus 0.5% to 0.6% and are scheduled to mature in January 2028 and 2030. In March 2019, we entered into an unsecured Japanese yen term loan agreement (the “March 2019 Yen Term Loan”) under which we can draw Japanese yen in an aggregate amount not to exceed ¥85.0 billion ($787.1 million at September 30, 2019). The March 2019 Yen Term Loan currently bears interest at Yen LIBOR plus 0.4% and is scheduled to mature in March 2026. We have the ability to increase the March 2019 Yen Term Loan to ¥120.0 billion ($1.1 billion at September 30, 2019), subject to obtaining additional lender commitments. Pricing under the March 2019 Yen Term Loan, including the spread over LIBOR, facility fees and letter of credit fees, varies based on the public debt ratings of the OP. We repaid the outstanding balance of ¥100.0 billion ($897.4 million) on our 2016 Japanese yen term loan, which bore interest at Yen LIBOR plus 0.7% and had two separate tranches of debt scheduled to mature in August 2022 and 2023, with the proceeds from the March 2019 Yen Term Loan during the first quarter of 2019. During the nine months ended September 30, 2019 and 2018, we paid down $1.3 billion and $1.5 billion, and reborrowed $777.2 million and $1.4 billion, respectively, on the 2017 Term Loan. Long-Term Debt Maturities Scheduled principal payments due on our debt for the remainder of 2019 and for each year through the period ended December 31, 2023, and thereafter were as follows at September 30, 2019 (in thousands): Unsecured Senior Term Loans Secured Maturity Notes and Other Mortgage Total 2019 (1) $ - $ 11,195 $ 2,214 $ 13,409 2020 (1) 435,560 - 34,463 470,023 2021 762,230 - 96,111 858,341 2022 762,230 - 12,149 774,379 2023 850,000 128,701 38,608 1,017,309 Thereafter 6,696,455 1,314,940 402,323 8,413,718 Subtotal 9,506,475 1,454,836 585,868 11,547,179 Premiums (discounts), net (46,629 ) - 609 (46,020 ) Debt issuance costs, net (30,009 ) (9,052 ) (2,875 ) (41,936 ) Total $ 9,429,837 $ 1,445,784 $ 583,602 $ 11,459,223 (1) We expect to repay the amounts maturing in the next twelve months with the remaining proceeds from the senior notes issuance in September 2019 discussed above, cash generated from operations, proceeds from dispositions of real estate properties, or as necessary, with additional borrowings. Losses on Early Extinguishment of Debt, Net During the nine months ended September 30, 2019, we recognized $16.1 million in losses on early extinguishment of debt, primarily from the redemption of €600.0 million ( During the nine months ended September 30, 2018, we recognized $2.7 million in losses, primarily due to the extinguishment of $1.8 billion of debt assumed in the DCT Transaction. The loss associated with the DCT Transaction represented the excess of the prepayment penalties of $ million over the $ million premium recorded upon assumption of the debt. Financial Debt Covenants We have $9.4 billion of senior notes and $1.4 billion of term loans outstanding at September 30, 2019 that were subject to certain financial covenants under their related indentures. We are also subject to financial covenants under our Credit Facilities and certain secured mortgage debt. At September 30, 2019, we were in compliance with all of our financial debt covenants. Guarantee of Finance Subsidiary Debt In 2018, we formed finance subsidiaries as part of our operations in Europe (Prologis Euro Finance LLC), Japan (Prologis Yen Finance LLC) and the United Kingdom (Prologis Sterling Finance LLC). These entities are 100% indirectly owned by the OP and all unsecured debt issued or to be issued by each entity is or will be fully and unconditionally guaranteed by the OP.

These entities include two real estate partnerships that have issued limited partnership units to third parties. Depending on the specific partnership agreements, these limited partnership units are redeemable for cash or, at our option, into shares of the Parent’s common stock, generally at a rate of one share of common stock to one limited partnership unit. We also consolidate certain entities in which we do not own 100% of the equity but the equity of these entities is not exchangeable into our common stock. Prologis, Inc. The noncontrolling interests of the Parent include the noncontrolling interests described above for the OP, as well as the limited partnership units in the OP that are not owned by the Parent. The following table summarizes our ownership percentages and noncontrolling interests and the consolidated entities’ total assets and liabilities (dollars in thousands): Our Ownership Percentage Noncontrolling Interests Total Assets Total Liabilities Sep 30, 2019 Dec 31, 2018 Sep 30, 2019 Dec 31, 2018 Sep 30, 2019 Dec 31, 2018 Sep 30, 2019 Dec 31, 2018 Prologis U.S. Logistics Venture 55.0 % 55.0 % $ 2,667,395 $ 2,697,095 $ 6,034,228 $ 6,072,087 $ 116,752 $ 92,782 Other consolidated entities (1 ) various various 109,629 139,374 1,019,943 1,045,202 91,296 53,145 Prologis, L.P. 2,777,024 2,836,469 7,054,171 7,117,289 208,048 145,927 Limited partners in Prologis, L.P.

Long-Term Compensation	NOTE 8. LONG-TERM COMPENSATION Equity-Based Compensation Plans and Programs Prologis Outperformance Plan (“POP”) We allocate participation points to participants under our POP corresponding to three-year performance periods beginning every January 1. The fair value of the awards is measured at the grant date and amortized over the period from the grant date to the date at which the awards vest, which ranges from three to ten years. The performance hurdle (“Outperformance Hurdle”) at the end of the initial three-year performance period requires our three-year compound annualized total stockholder return (“TSR”) to exceed a threshold set at the three -year compound annualized TSR for the Morgan Stanley Capital International (“MSCI”) US REIT Index for the same period plus 100 basis points. If the Outperformance Hurdle is met, a compensation pool will be formed equal to 3% of the excess value created, subject to a maximum as defined for each performance period. POP awards cannot be paid at a time when our absolute TSR is negative. If after seven years our absolute TSR has not been positive, the awards will be forfeited. We granted participation points for the 2019 – 2021 performance period in January 2019, with a fair value of $21.2 million using a Monte Carlo valuation model that assumed a risk-free interest rate of 2.6% and an expected volatility of 20.0%. The 2019 – 2021 performance period has an absolute maximum cap of $100 million. If an award is earned at the end of the initial three-year performance period, then 20% of the POP award is paid and the remaining 80% is subject to additional seven-year cliff vesting. The 20% that is paid at the end of the three-year performance period is subject to an additional three-year holding requirement. The Outperformance Hurdle was met for the 2016 – 2018 performance period, which resulted in awards being earned at December 31, 2018. Initial awards of $75.0 million in aggregate were awarded in January 2019 in the form of 0.4 million shares of common stock and 0.8 million POP LTIP Units and LTIP Units. Participants are not able to sell or transfer equity awards received until three years after the end of the initial period. One-third of the remaining compensation pool in excess of the $75.0 million aggregate initial award amounts can be earned at the end of each of the three years following the end of the initial three-year performance period if our performance meets or exceeds the MSCI US REIT Index. Vesting for the 2016 – 2018 performance period for our Named Executive Officers (“NEOs”) follows the construct of the 2019 – 2021 performance period as described above, such that 20% of any amounts earned were awarded subject to a three-year holding period, and 80% of any amounts earned will cliff vest at the end of the seventh year following the initial three-year performance period. At September 30, 2019, there were 0.4 million unvested POP LTIP Units associated with the 2016 – 2018 performance period. Other Equity-Based Compensation Plans and Programs Our other equity-based compensation plans and programs include (i) the Prologis Promote Plan (“PPP”); (ii) the annual long-term incentive (“LTI”) equity award program (“Annual LTI Award”); and (iii) the annual bonus exchange program. Awards under these plans and programs may be issued in the form of restricted stock units (“RSUs”) or LTIP Units at the participant’s election. RSUs and LTIP Units are valued based on the market price of the Parent’s common stock on the date the award is granted and the grant date value is charged to compensation expense over the service period, which beginning in February 2018 was lengthened from three to four years for PPP and Annual LTI Awards and three years for bonus exchange awards offering a premium upon exchange. As our NEOs do not receive a bonus exchange premium for participating in the bonus exchange program, the equity they receive upon exchange for their cash bonuses does not have a vesting period.

Earnings Per Share [Abstract]
Earnings Per Common Share or Unit	NOTE 9. EARNINGS PER COMMON SHARE OR UNIT We determine basic earnings per share or unit based on the weighted average number of shares of common stock or units outstanding during the period. We compute diluted earnings per share or unit based on the weighted average number of shares or units outstanding combined with the incremental weighted average effect from all outstanding potentially dilutive instruments. The computation of our basic and diluted earnings per share and unit was as follows (in thousands, except per share and unit amounts): Three Months Ended Nine Months Ended September 30, September 30, Prologis, Inc. 2019 2018 2019 2018 Net earnings attributable to common stockholders – Basic $ 450,639 $ 346,345 $ 1,181,470 $ 1,046,858 Net earnings attributable to exchangeable limited partnership units (1) 13,422 10,593 35,838 31,502 Adjusted net earnings attributable to common stockholders – Diluted $ 464,061 $ 356,938 $ 1,217,308 $ 1,078,360 Weighted average common shares outstanding – Basic 630,929 574,520 630,356 546,612 Incremental weighted average effect on exchange of limited partnership units (1) 18,760 18,153 19,403 17,097 Incremental weighted average effect of equity awards 5,570 4,974 5,059 4,890 Weighted average common shares outstanding – Diluted (2) 655,259 597,647 654,818 568,599 Net earnings per share attributable to common stockholders: Basic $ 0.71 $ 0.60 $ 1.87 $ 1.92 Diluted $ 0.71 $ 0.60 $ 1.86 $ 1.90 Three Months Ended Nine Months Ended September 30, September 30, Prologis, L.P. 2019 2018 2019 2018 Net earnings attributable to common unitholders $ 463,997 $ 356,765 $ 1,217,088 $ 1,077,823 Net earnings attributable to Class A Units (5,840 ) (5,039 ) (15,523 ) (16,216 ) Net earnings attributable to common unitholders – Basic 458,157 351,726 1,201,565 1,061,607 Net earnings attributable to Class A Units 5,840 5,039 15,523 16,216 Net earnings attributable to exchangeable other limited partnership units 64 173 220 537 Adjusted net earnings attributable to common unitholders – Diluted $ 464,061 $ 356,938 $ 1,217,308 $ 1,078,360 Weighted average common partnership units outstanding – Basic 641,229 583,363 641,077 554,313 Incremental weighted average effect on exchange of Class A Units 8,154 8,412 8,282 8,467 Incremental weighted average effect on exchange of other limited partnership units 306 898 400 929 Incremental weighted average effect of equity awards of Prologis, Inc. 5,570 4,974 5,059 4,890 Weighted average common units outstanding – Diluted (2) 655,259 597,647 654,818 568,599 Net earnings per unit attributable to common unitholders: Basic $ 0.71 $ 0.60 $ 1.87 $ 1.92 Diluted $ 0.71 $ 0.60 $ 1.86 $ 1.90 (1) The exchangeable limited partnership units include the units as discussed in Note 7.

Fair Value Measurements on a Recurring Basis At September 30, 2019 and December 31, 2018, other than the derivatives discussed previously, we did not have any significant financial assets or financial liabilities that were measured at fair value on a recurring basis in the Consolidated Financial Statements. All of our derivatives held at September 30, 2019 and December 31, 2018, were classified as Level 2 of the fair value hierarchy. Fair Value Measurements on Nonrecurring Basis Acquired properties and assets we expect to sell or contribute met the criteria to be measured on a nonrecurring basis at fair value and the lower of their carrying amount or their estimated fair value less the costs to sell, respectively, at September 30, 2019 and December 31, 2018. At September 30, 2019 and December 31, 2018, we estimate the fair value of our properties using Level 2 or Level 3 inputs from the fair value hierarchy. See more information on our acquired properties and assets held for sale or contribution in Notes 2, 3 and 5, respectively. Fair Value of Financial Instruments At September 30, 2019 and December 31, 2018, the carrying amounts of certain financial instruments, including cash and cash equivalents, accounts and notes receivable, accounts payable and accrued expenses were representative of their fair values. The differences in the fair value of our debt from the carrying value in the table below were the result of differences in interest rates or borrowing spreads that were available to us at September 30, 2019 and December 31, 2018, as compared with those in effect when the debt was issued or assumed, including reduced borrowing spreads due to our improved credit ratings. The senior notes and many of the issuances of secured mortgage debt contain pre-payment penalties or yield maintenance provisions that could make the cost of refinancing the debt at lower rates exceed the benefit that would be derived from doing so.

Segment Reporting [Abstract]
Business Segments	NOTE 11. BUSINESS SEGMENTS Our current business strategy includes two operating segments: Real Estate Operations and Strategic Capital. We generate revenues, earnings, net operating income and cash flows through our segments, as follows: • Real Estate Operations. This operating segment represents the ownership and development of operating properties and is the largest component of our revenue and earnings. We collect rent from our customers through operating leases, including reimbursements for the majority of our property operating costs. Each operating property is considered to be an individual operating segment with similar economic characteristics; these properties are combined within the reportable business segment based on geographic location. Our Real Estate Operations segment also includes development activities that lead to rental operations, including land held for development and properties currently under development. Within this line of business, we utilize the following: (i) our land bank; (ii) the development expertise of our local teams; and (iii) our customer relationships. Land we own and lease to customers under ground leases, along with land and buildings we lease, is also included in this segment. • Strategic Capital. This operating segment represents the management of unconsolidated co-investment ventures. We generate strategic capital revenues primarily from our unconsolidated co-investment ventures through asset management and property management services and we earn additional revenues by providing leasing, acquisition, construction, development, financing, legal and disposition services. Depending on the structure of the venture and the returns provided to our partners, we also earn revenues through promotes periodically during the life of a venture or upon liquidation.

Accounting Policies [Abstract]
Business	Business . Prologis, Inc. (or the “Parent”) commenced operations as a fully integrated real estate company in 1997, elected to be taxed as a real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Internal Revenue Code”), and believes the current organization and method of operation will enable it to maintain its status as a REIT. The Parent is the general partner of Prologis, L.P. (or the “Operating Partnership” or “OP”). Through the OP, we are engaged in the ownership, acquisition, development and management of logistics facilities with a focus on key markets in 19 countries on four continents. We invest in real estate through wholly owned subsidiaries and other entities through which we co-invest with partners and investors. We maintain a significant level of ownership in these co-investment ventures, which may be consolidated or unconsolidated based on our level of control of the entity. Our current business strategy consists of two operating business segments: Real Estate Operations and Strategic Capital. Our Real Estate Operations segment represents the ownership and development of logistics properties. Our Strategic Capital segment represents the management of unconsolidated co-investment ventures and other ventures. See Note 11 for further discussion of our business segments. Unless otherwise indicated, the Notes to the Consolidated Financial Statements apply to both the Parent and the OP. The terms “the Company,” “Prologis,” “we,” “our” or “us” means the Parent and OP collectively For each share of preferred or common stock the Parent issues, the OP issues a corresponding preferred or common partnership unit, as applicable, to the Parent in exchange for the contribution of the proceeds from the stock issuance. At September 30, 2019, the Parent owned a 97.22% common general partnership interest in the OP and 100% of the preferred units in the OP. The remaining 2.78% common limited partnership interests, which include 8.6 million Class A common limited partnership units (“Class A Units”) in the OP, are owned by unaffiliated investors and certain current and former directors and officers of the Parent. Each partner’s percentage interest in the OP is determined based on the number of OP units held, including the number of OP units into which Class A Units are convertible, compared to total OP units outstanding at each period end and is used as the basis for the allocation of net income or loss to each partner. At the end of each reporting period, a capital adjustment is made in the OP to reflect the appropriate ownership interest for each of the common unitholders. These adjustments are reflected in the line items Reallocation of Equity Reallocation of Capital As the sole general partner of the OP, the Parent has complete responsibility and discretion in the day-to-day management and control of the OP and we operate the Parent and the OP as one enterprise. The management of the Parent consists of the same members as the management of the OP. These members are officers of the Parent and employees of the OP or one of its subsidiaries. As general partner with control of the OP, the Parent is the primary beneficiary and therefore consolidates the OP. Because the Parent’s only significant asset is its investment in the OP, the assets and liabilities of the Parent and the OP are the same on their respective financial statements.
Basis of Presentation	Basis of Presentation. The accompanying Consolidated Financial Statements are prepared in accordance with United States (“U.S.”) generally accepted accounting principles (“GAAP”) and are presented in our reporting currency, the U.S. dollar. References herein to the translation of activity for significant nonrecurring transactions are at the rate in effect at the date of the transaction. All material intercompany transactions with consolidated entities have been eliminated. The accompanying unaudited interim financial information has been prepared according to the rules and regulations of the U.S. Securities and Exchange Commission (“SEC”). Certain information and note disclosures normally included in our annual financial statements prepared in accordance with GAAP have been condensed or omitted in accordance with such rules and regulations. Our management believes that the disclosures presented in these financial statements are adequate to make the information presented not misleading. In our opinion, all adjustments and eliminations, consisting only of normal recurring adjustments, necessary to present fairly the financial position and results of operations for both the Parent and the OP for the reported periods have been included. The results of operations for such interim periods are not necessarily indicative of the results for the full year. The accompanying unaudited interim financial information should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2018, as filed with the SEC, and other public information.
Reclassification	Reclassifications. Upon adoption of the new lease standard, rental recoveries for 2018 have been reclassified to Rental Revenues in the Consolidated Statements of Income to conform to the 2019 financial statement presentation.
New Accounting Pronouncements	New Accounting Pronouncements. New Accounting Standards Adopted Leases. In February 2016, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update (“ASU”) that provided the principles for the recognition, measurement, presentation and disclosure of leases. The guidance amended the existing accounting standards, including the requirement that lessees recognize right-of-use assets and lease liabilities for leases with terms greater than twelve months in the Consolidated Balance Sheets. Additional guidance and targeted improvements to the February 2016 ASU were made through the issuance of supplementary ASUs in July 2018, December 2018 and March 2019. We refer to all four ASUs collectively as the “new lease standard.” We adopted the new lease standard on January 1, 2019 and applied it to leases that were in place on the effective date. Results for reporting periods beginning January 1, 2019 are presented under the new lease standard. We elected the package of practical expedients and were not required to reassess the following upon adoption: (i) whether an expired or existing contract met the definition of a lease; (ii) the lease classification at January 1, 2019 for existing leases; and (iii) whether leasing costs previously capitalized as initial direct costs would continue to be amortized. This allowed us to continue to account for our existing ground and office space leases as operating leases, however, any new or renewed ground leases after January 1, 2019 may be classified as financing leases unless they meet certain conditions to be considered a lease involving land owned by a government unit or authority. Upon adoption, we did not have an adjustment to the opening balance of retained earnings due to the election of these practical expedients. • As a lessor. The new lease standard requires that lessors expense, on an as-incurred basis, certain initial direct costs that are not incremental in negotiating a lease. Initial direct costs include the salaries and related costs for employees directly working on leasing activities. Prior to January 1, 2019, these costs were capitalizable in Other Assets and therefore the new lease standard resulted in certain of these costs being expensed as incurred through Rental Expenses . During the three and nine months ended September 30, 2018, we capitalized $5.2 million and $15.7 million, respectively, of internal costs related to our leasing activities. We will continue to amortize initial direct costs capitalized prior to January 1, 2019. We adopted the practical expedient that allowed us to not separate expenses reimbursed by our customers (“rental recoveries”) from the associated rental revenue if certain criteria were met. We assessed these criteria and concluded that the timing and straight-line pattern of transfer to the lessee for rental revenue and the associated rental recoveries are the same and as our leases qualify as operating leases, we accounted for and presented rental revenue and rental recoveries as a single component under Rental Revenues • As a lessee. At January 1, 2019 we recognized Lease Right-of-Use (“ROU”) Assets and Lease Liabilities , principally for our ground and office space leases, in which we are the lessee. See Note 3 for further disclosure around our adoption of the new lease standard. Derivatives and Hedging . In August 2017, the FASB issued an ASU that simplified the application of hedge accounting guidance in current GAAP and improved the reporting of hedging relationships to better portray the economic results of an entity’s risk management activities in its consolidated financial statements. Among the simplification updates, the ASU eliminated the requirement in current GAAP to separately recognize periodic hedge ineffectiveness. Mismatches between the changes in value of the hedged item and hedging instrument may still occur but they will no longer be separately reported. The ASU required the presentation of the earnings effect of the hedging instrument in the same income statement line item in which the earnings effect of the hedged item is reported. We adopted the ASU on January 1, 2019 on a modified retrospective basis and there was no adjustment to the opening balance of retained earnings.

($134.4 million and $122.0 million, respectively) (3) Represents our weighted average ownership interest based on each entity’s contribution of total assets, before depreciation, net of other liabilities.

The difference between our ownership interest of a venture’s equity and our investment balance at September 30, 2019 and December 31, 2018, results principally from four types of transactions: (i) deferred gains from the contribution of property to a venture prior to January 1, 2018; (ii) recording additional costs associated with our investment in the venture; (iii) receivables, principally for fees and promotes ($258.0 million and $166.7 million, respectively); and (iv) customer security deposits retained subsequent to property contributions to Nippon Prologis REIT, Inc. ($134.4 million and $122.0 million, respectively)
[2]	PBLV and our other Brazilian joint ventures are combined as one venture for the purpose of this table.
