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”). Through the Operating Partnership, we are engaged in the ownership, acquisition, development and management of logistics properties in the world’s primary population centers and in those supported by extensive transportation infrastructure. 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 co-investment ventures and other unconsolidated entities. See Note 10 for further discussion of our business segments. Unless otherwise indicated, the Notes to the Consolidated Financial Statements apply to both the Parent and the Operating Partnership. The terms “the Company,” “Prologis,” “we,” “our” or “us” means the Parent and Operating Partnership collectively. For each share of common stock or preferred stock the Parent issues, the Operating Partnership issues a corresponding common or preferred partnership unit, as applicable, to the Parent in exchange for the contribution of the proceeds from the stock issuance. At March 31, 2017, the Parent owned an approximate 97.31% common general partnership interest in the Operating Partnership and 100% of the preferred units in the Operating Partnership. The remaining approximate 2.69% common limited partnership interests, which include 8.9 million Class A common limited partnership units (“Class A Units”) in the Operating Partnership, are owned by unaffiliated investors and certain current and former directors and officers of the Parent. Each partner’s percentage interest in the Operating Partnership is determined based on the number of Operating Partnership units held, including the number of Operating Partnership units into which Class A Units are convertible, compared to total Operating Partnership 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 Operating Partnership 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 Statement of Equity and Reallocation of Capital in the Consolidated Statement of Capital. As the sole general partner of the Operating Partnership, the Parent has complete responsibility and discretion in the day-to-day management and control of the Operating Partnership and we operate the Parent and the Operating Partnership as one enterprise. The management of the Parent consists of the same members as the management of the Operating Partnership. These members are officers of the Parent and employees of the Operating Partnership or one of its subsidiaries. As general partner with control of the Operating Partnership, the Parent consolidates the Operating Partnership. Because the Parent’s only significant asset is its investment in the Operating Partnership, the assets and liabilities of the Parent and the Operating Partnership 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 footnote 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 Operating Partnership 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 fiscal year ended December 31, 2016, as filed with the SEC, and other public information. Certain amounts included in the accompanying Consolidated Financial Statements for 2016 have been reclassified to conform to the 2017 financial statement presentation. This included two reclassifications made in the Consolidated Statements of Cash Flows. The first was a reclassification of distributions from our unconsolidated entities from investing activities to operating activities due to the adoption of the accounting standard update that provided guidance for areas in which there was diversity in how certain cash receipts and payments were presented and classified. The second was the reclassification of payments from operating activities to financing activities due to the accounting standard update that amended the stock compensation requirements in existing GAAP. New Accounting Pronouncements. New Accounting Standards Adopted In January 2017, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update that clarifies the definition of a business. The update adds further guidance that assists preparers in evaluating whether a transaction will be accounted for as an acquisition of an asset or a business. We expect most of our acquisitions of operating properties and portfolios of operating properties to qualify as asset acquisitions under the standard that permits the capitalization of acquisition costs to the basis of the acquired buildings. We adopted this standard on January 1, 2017, on a prospective basis, and the adoption did not have a significant impact on the Consolidated Financial Statements. New Accounting Standards Issued but not yet Adopted Revenue Recognition. In May 2014, the FASB issued an accounting standard that requires companies to use a five-step model to determine when to recognize revenue from customer contracts in an effort to increase consistency and comparability throughout global capital markets and across industries. We are evaluating each of our revenue streams and related accounting policy under the standard. Rental revenues and recoveries earned from leasing our operating properties will be evaluated with the adoption of the lease accounting standard (discussed below). Our evaluation under the revenue recognition standard also includes sales to third parties and unconsolidated co-investment ventures as well as recurring fees and promotes earned from our co-investment ventures. While we do not expect changes in the recognition of recurring fees earned from the co-investment ventures, we are evaluating both the timing and measurement of promotes earned from co-investment ventures that may result in recognizing such fees when they are probable of being earned. For sales to third parties, primarily a disposition of real estate in exchange for cash with few contingencies, we do not expect the standard to significantly impact the recognition of or accounting for these sales. In February 2017, in connection with the revenue recognition standard, the FASB issued a standard that provides the accounting treatment for gains and losses from the derecognition of non-financial assets, including the accounting for partial sales. Upon adoption of the standard, we will recognize the entire gain attributed to sales to unconsolidated co-investment ventures rather than the third party share we recognize today. Both the revenue recognition and derecognition of non-financial assets standards are effective for us on January 1, 2018. In addition to the recognition changes discussed above, expanded quantitative and qualitative disclosures regarding revenue recognition will be required for contracts that are subject to the standard. We expect to adopt the standards on a modified retrospective basis. Leases. In February 2016, the FASB issued an accounting standard that provides the principles for the recognition, measurement, presentation and disclosure of leases. The accounting for lessors will remain largely unchanged from current GAAP; however, the standard requires that lessors expense, on an as-incurred basis, certain initial direct costs that are not incremental in negotiating a lease. Under existing standards, certain of these costs are capitalizable and therefore this new standard may result in certain of these costs being expensed as incurred after adoption. This standard may also impact the timing, recognition and disclosures related to our rental recoveries from tenants earned from leasing our operating properties. Under the standard, lessees apply a dual approach, classifying leases as either finance or operating leases. A lessee is required to record a right-of-use asset and a lease liability for all leases with a term of greater than 12 months, regardless of their lease classification. We are a lessee on ground leases in certain markets and office space leases. At December 31, 2016, we had approximately 90 ground and office space leases that will require us to measure and record a right-of-use asset and a lease liability upon adoption of the standard. There have been no significant changes to our ground and office space leases since December 31, 2016. The standard is effective for us on January 1, 2019. We are assessing the practical expedients available for implementation under the standard. If the practical expedients are elected, we would not be required to reassess (i) whether an expired or existing contract meets the definition of a lease, (ii) the lease classification at the adoption date for expired or existing leases, and (iii) whether costs previously capitalized as initial direct costs would continue to be amortized. The standard will also require new disclosures within the notes accompanying our Consolidated Financial Statements. We will continue to assess the method of adoption and the overall impact the adoption will have on the Consolidated Financial Statements.
