General [Abstract]
Business	*Business.* On June 3, 2011, AMB Property Corporation (“AMB”) and AMB Property, LP completed the merger contemplated by the Agreement and Plan of Merger with ProLogis, a Maryland real estate investment trust (“ProLogis”) and its subsidiaries (the “Merger”). Following the Merger, AMB changed its name to Prologis, Inc. (the “REIT”). As a result of the Merger, each outstanding common share of beneficial interest of ProLogis was converted into 0.4464 of a newly issued share of common stock of the REIT. As further discussed in Note 2, AMB was the legal acquirer and ProLogis was the accounting acquirer. Prologis, Inc. commenced operations as a fully integrated real estate company in 1997, elected to be taxed as a real estate investment trust under the Internal Revenue Code of 1986, as amended, and believes the current organization and method of operation will enable the REIT to maintain its status as a real estate investment trust. The REIT is the general partner of Prologis, L.P. (the “Operating Partnership”). Through our controlling interest in the Operating Partnership, we are engaged in the ownership, acquisition, development and operation of industrial properties in global, regional and other distribution markets throughout the Americas, Europe and Asia. Our current business strategy includes two reportable business segments: Real Estate Operations and Private Capital. Our Real Estate Operations segment represents the long-term ownership of industrial properties. Our Private Capital segment represents the long-term management of co-investment ventures and other unconsolidated entities. See Note 15 for further discussion of our business segments. Unless otherwise indicated, the notes to the Consolidated Financial Statements apply to both the REIT and the Operating Partnership. The terms “the Company”, “Prologis”, “we”, “our” or “us” means the REIT and Operating Partnership collectively. As of June 30, 2012, the REIT owned an approximate 99.59% common general partnership interest in the Operating Partnership, and 100% of the preferred units. The remaining approximate 0.41% common limited partnership interest is owned by non-affiliated investors and certain current and former directors and officers of the REIT. As the sole general partner of the Operating Partnership, the REIT has full, exclusive and complete responsibility and discretion in the day-to-day management and control of the Operating Partnership. We operate the REIT and the Operating Partnership as one enterprise. The management of the REIT consists of the same members as the management of the Operating Partnership. These members are officers of the REIT and employees of the Operating Partnership or one of its direct or indirect subsidiaries. As general partner with control of the Operating Partnership, the REIT consolidates the Operating Partnership for financial reporting purposes, and the REIT does not have significant assets other than its investment in the Operating Partnership. Therefore, the assets and liabilities of the REIT and the Operating Partnership are the same on their respective financial statements.
Basis of Presentation	*Basis of Presentation.* The accompanying consolidated financial statements, presented in the U.S. dollar, are prepared in accordance with U.S. generally accepted accounting principles (“GAAP”). GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities as of the date of the financial statements and revenue and expenses during the reporting period. Our actual results could differ from those estimates and assumptions. 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 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 REIT 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 the December 31, 2011 Consolidated Financial Statements of Prologis, as previously filed with the SEC on Form 10-K and other public information. Certain amounts included in the accompanying Consolidated Financial Statements for 2011 have been reclassified to conform to the 2012 financial statement presentation.
Recent Accounting Pronouncements	*Recent Accounting Pronouncements.* In December 2011, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update that requires disclosures about offsetting and related arrangements to enable financial statements users to evaluate the effect or potential effect of netting arrangements on an entity’s financial position, including rights of setoff associated with certain financial instruments and derivative instruments. The disclosure requirements are effective for us on January 1, 2013, and we do not expect the guidance to have a material impact on our Consolidated Financial Statements. In December 2011, the FASB issued an accounting standard update to clarify the scope of current U.S. GAAP. The update clarifies that the real estate sales guidance applies to the derecognition of a subsidiary that is in-substance real estate as a result of default on the subsidiary’s nonrecourse debt. That is, even if the reporting entity ceases to have a controlling financial interest under the consolidation guidance, the reporting entity would continue to include the real estate, debt, and the results of the subsidiary’s operations in its consolidated financial statements until legal title to the real estate is transferred to legally satisfy the debt. This accounting standard update is effective for us on January 1, 2013, and we do not expect the guidance to impact our Consolidated Financial Statements. In September 2011, the FASB issued an accounting standard update to amend and simplify the rules related to testing goodwill for impairment. The update allows an entity to make an initial qualitative evaluation, based on the entity’s events and circumstances, to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The results of this qualitative assessment determine whether it is necessary to perform the currently required two-step impairment test. The new guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We adopted this standard as of January 1, 2012 and it has not had a material impact on our Consolidated Financial Statements.
