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 12 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 March 31, 2020, the Parent owned a 97.21% common general partnership interest in the OP and 100% of the preferred units in the OP. The remaining 2.79% 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 in the Consolidated Statements of Equity of the Parent and Reallocation of Capital in the Consolidated Statements of Capital of the OP. 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. 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, 2019, as filed with the SEC, and other public information. New Accounting Pronouncements. Accounting for Lease Concessions Related to the Effects of the Coronavirus (“COVID-19”) Pandemic. In April 2020, the Financial Accounting Standards Board (“FASB”) issued a Staff Question-and-Answer (“Q&A”) to clarify whether lease concessions related to the effects of COVID-19 require the application of the lease modification guidance under the new lease standard, which we adopted on January 1, 2019. For rent deferrals granted as of April 27^th, we are allowing customers to defer rental payments until later in 2020, in exchange for a note receivable, and we are continuing to recognize rental revenue during the period. In accordance with the Q&A, we are electing to not apply the lease modification guidance to concessions that result in deferred rent as the total cash flows required by the modified lease agreements are materially the same as the cash flows required under the original lease and there are no substantive changes to the consideration. As of April 27, 2020, we have granted deferral requests of $8.6 million with an average of 30 days of rent deferred per customer. If we grant concessions to a customer that modify the terms and significantly change the underlying cash flows of the original lease for the remaining term, we will account for these changes as a lease modification. Reference Rate Reform. In March 2020, the FASB issued an Accounting Standard Update (“ASU”) that provided practical expedients to address existing guidance on contract modifications and hedge accounting due to the expected market transition from the London Inter-bank Offered Rate (“LIBOR”) and other interbank offered rates (together “IBORs”) to alternative reference rates, such as the Secured Overnight Financing Rate. In July 2017, the Financial Conduct Authority announced it intended to stop compelling banks to submit rates for the calculation of LIBOR after 2021. We refer to this transition as “reference rate reform.” The first practical expedient allows companies to elect to not apply certain modification accounting requirements to debt, derivative and lease contracts affected by reference rate reform if certain criteria are met. These criteria include the following: (i) the contract referenced an IBOR rate that is expected to be discontinued; (ii) the modified terms directly replace or have the potential to replace the IBOR rate that is expected to be discontinued; and (iii) any contemporaneous changes to other terms that change or have the potential to change the amount and timing of contractual cash flows must be related to the replacement of the IBOR rate. If the contract meets all three criteria, there is no requirement for remeasurement of the contract at the modification date or reassessment of the previous accounting determination. The second practical expedient allows companies to change the reference rate and other critical terms related to the reference rate reform in derivative hedge documentation without having to de-designate the hedging relationship. This allows for companies to continue applying hedge accounting to existing cash flow and net investment hedges. The ASU was effective upon issuance on a prospective basis beginning January 1, 2020 and may be elected over time as reference rate reform activities occur. During the first quarter of 2020, we elected to apply the hedge accounting practical expedient to our net investment hedges and cash flow hedges. We will continue to evaluate our debt, derivative and lease contracts that are eligible for modification relief and may apply those elections as needed.
