Accounting Policies [Abstract]
General	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 operation of industrial properties in global and regional markets throughout the Americas, Europe and Asia. Our current business strategy is comprised of two operating business segments: Real Estate Operations and Strategic Capital. Our Real Estate Operations segment represents the ownership of industrial properties. Our Strategic Capital segment represents the management of co-investment ventures and other unconsolidated entities. See Note 13 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, 2015, the Parent owned an approximate 99.62% common general partnership interest in the Operating Partnership, and 100% of the preferred units in the Operating Partnership. The remaining approximate 0.38% common limited partnership interests are owned by non-affiliated investors and certain current and former directors and officers of the Parent. As the sole general partner of the Operating Partnership, the Parent has full, exclusive and complete responsibility and discretion in the day-to-day management and control of the Operating Partnership.

	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. Since 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 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 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 the 2014 Consolidated Financial Statements as previously filed with the SEC on Form 10-K and other public information.

	Recent Accounting Pronouncements. In April 2015, the Financial Accounting Standards Board (the “FASB”) issued an accounting standard update that requires the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015, but early adoption is permitted. At March 31, 2015, we had $50.1 million of debt issuance costs in Other Assets in the Consolidated Balance Sheets that would be subject to the reclassification.

	In February 2015, the FASB issued an accounting standard update that amends the consolidation requirements in existing GAAP. Under the update, all entities, including limited partnerships and similar legal entities, are now within the scope of consolidation guidance, unless a scope exception applies. The presumption that a general partner controls a limited partnership has been eliminated. In addition, fees paid to decision makers that meet certain conditions no longer cause the decision makers to consolidate variable interest entities (“VIEs”). It is effective for annual reporting periods beginning after December 15, 2015, but early adoption is permitted and allows for either a full retrospective or a modified retrospective adoption approach. We are currently evaluating the impact the adoption of this standard will have on the Consolidated Financial Statements.

	In May 2014, the FASB issued an accounting standard update 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. Under the model, a company will identify the contract, identify any separate performance obligations in the contract, determine the transaction price, allocate the transaction price and recognize revenue when the performance obligation is satisfied. In April 2015, the FASB proposed deferring the effective date by one year to December 15, 2017, for annual reporting periods beginning after that date. The FASB also proposed permitting early adoption of the standard, but not before the original effective date of December 15, 2016. We are currently evaluating the impact the adoption of this standard will have on the Consolidated Financial Statements.

	Acquisition of a Controlling Interest in Prologis North American Industrial Fund (“NAIF”)

	During 2014, we increased our ownership in NAIF from 23.1% to 66.1% by acquiring the equity units from all but one partner for an aggregate of $679.0 million. This included the acquisition of $46.8 million on October 20, 2014, that resulted in our gaining control over NAIF, based on the rights of the limited partners, and therefore we began consolidating NAIF as of that date.

	The total purchase price was $1.1 billion, which included our investment in NAIF at the time of consolidation. The allocation of the purchase price required a significant amount of judgment and was based on our valuation, estimates and assumptions of the acquisition date fair value of the tangible and intangible assets acquired and liabilities assumed, for which we used external valuations as appropriate. While the current allocation of the purchase price is substantially complete, the valuation of the real estate properties is still being finalized. We do not expect future revisions, if any, to have a significant impact on our financial position or results of operations.

	The allocation of the purchase price was as follows (in thousands):



	Investments in real estate properties	$	2,770,191
	Cash, accounts receivable and other assets		132,261
	Debt		(1,195,213	)

	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 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 accounted for using the equity method of accounting. See Note 9 for more detail regarding our consolidated investments.

	We also have other ventures, generally with one partner and that we do not manage, which we account for on the equity method. We refer to our investments in all entities accounted for under the equity method, both unconsolidated co-investment ventures and other ventures, collectively, as unconsolidated entities.

	Our investments in and advances to our unconsolidated entities are summarized below (in thousands):

			March 31,				December 31,
			2015				2014
	Unconsolidated co-investment ventures		$	4,381,650			$	4,665,918
	Other ventures			178,071				158,806
	Totals		$	4,559,721			$	4,824,724

	Unconsolidated Co-Investment Ventures

	The amounts recognized in Strategic Capital Income and Earnings from Unconsolidated Entities, Net in the Consolidated Statements of Operations depend on the size, operations of the co-investment ventures and fluctuations in foreign currency rates. Our ownership interest in these ventures also impacts the equity in earnings we recognize. The co-investment venture information represents the venture’s information (not our proportionate share) prepared on a GAAP basis. The following tables are summarized information of the unconsolidated co-investment ventures:

-1	The difference between our ownership interest of the venture’s equity and our investment balance results principally from three types of transactions: (i) deferring a portion of the gains we recognize from a contribution of a property to the venture; (ii) recording additional costs associated with our investment in the venture; and (iii) advances to the venture.

-2	At March 31, 2015 and December 31, 2014, we had receivables from Nippon Prologis REIT, Inc. (“NPR”) of $85.5 million and $85.9 million, respectively, related to customer security deposits that are made through a leasing company owned by Prologis that pertain to properties owned by NPR. There is a corresponding payable to NPR’s customers in Other Liabilities in the Consolidated Balance Sheets.

Equity Commitments Related to Certain Unconsolidated Co-Investment Ventures

Certain co-investment ventures have equity commitments from us and our venture partners. Our venture partners fulfill their equity commitment with cash. We may fulfill our equity commitment through contributions of properties or cash. The venture may obtain financing for the properties and therefore the acquisition price of additional investments that the venture could make may be more than the equity commitment. Depending on market conditions, the investment objectives of the ventures, our liquidity needs and other factors, we may make additional contributions of properties and/or additional cash investments in these ventures through the remaining commitment period. During the first quarter of 2015, we contributed $49.1 million of our commitment to Prologis European Logistics Partners for repayment of third-party debt by the venture. We did not enter into any additional equity commitments in the first quarter of 2015.

	-3	At March 31, 2015, we had outstanding borrowings on our euro term loan of $537.9 million and our Yen term loan was fully drawn.

	Credit Facilities

	We have a global senior credit facility (the “Global Facility”), under which we may draw in U.S. dollars, euro, Japanese yen, British pounds sterling and Canadian dollars on a revolving basis up to $2.3 billion subject to currency fluctuations, as of March 31, 2015. We also have a ¥45 billion ($375.5 million at March 31, 2015) Japanese yen revolver (the “Revolver”) with availability to increase to ¥56.5 billion. We refer to the Global Facility and the Revolver, collectively, as our “Credit Facilities.”

	Exchangeable Senior Notes

	During March 2015, the holders of the exchangeable notes exchanged $459.8 million of their notes for 11.9 million shares of the Parent and $0.2 million of their notes for cash.

	The fair value of the derivative associated with the exchangeable debt was a liability of $51.3 million at December 31, 2014. The fair value of the exchange option was $43.0 million immediately prior to the exchange in March 2015. When the debt was exchanged into common stock, the value of the derivative associated with the debt was reclassified to Additional Paid-In Capital in the Consolidated Balance Sheets. We recognized an unrealized gain due to the change in fair value of the derivative of $8.3 million and a loss of $22.8 million for the three months ended March 31, 2015 and 2014, respectively, in Foreign Currency and Derivative Gains (Losses) and Related Amortization, Net in the Consolidated Statements of Operations.

	Prologis, L.P.

	We report noncontrolling interests related to several entities we consolidate but of which we do not own 100% of the equity. 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 exchangeable into shares of the Parent’s common stock (or cash), generally at a rate of one share of common stock to one unit. We also consolidate several entities in which we do not own 100% of the equity and the units of the entity are not exchangeable into our common stock.

	Prologis, Inc.

	The noncontrolling interest of the Parent includes the noncontrolling interests presented in the Operating Partnership, as well as the common limited partnership units in the Operating Partnership that are not owned by the Parent.

	The following is a summary of the noncontrolling interests and the consolidated entity’s total investment in real estate and debt at March 31, 2015 and December 31, 2014 (dollars and units in thousands):

	-3	At March 31, 2015 and December 31, 2014, there were limited partnership units in the Operating Partnership that were exchangeable into cash or, at our option, 1,762 and 1,767 shares, respectively, of the Parent’s common stock. At March 31, 2015 and December 31, 2014, there were 993 and 113 LTIP Units (as defined in Note 10) outstanding, respectively, associated with our long-term compensation plan that are not exchangeable into the Parent’s common stock until they vest. All of these outstanding limited partnership units receive quarterly cash distributions equal to the quarterly distributions paid on our common stock pursuant to the terms of the partnership agreement.

Long-Term Compensation	10.Long-Term Compensation

	At March 31, 2015, we had points awarded under our Outperformance Plan (“OPP”) outstanding. We also had restricted stock, restricted stock units (“RSUs”), Operating Partnership units (“LTIP Units”), special outperformance plan type of LTIP Units (“OPP LTIP Units”) and stock options outstanding under our incentive plans. See details below.

	OPP

	We granted points under our OPP on February 10, 2015, with a fair value of $26.5 million as of the date of grant using a Monte Carlo valuation model that assumed a risk free interest rate of 0.86% and an expected volatility of 28%. Such points relate to a three-year performance period that began on January 1, 2015, and will end on December 31, 2017. As of March 31, 2015, we also have OPP points outstanding for the 2013-2015 and 2014-2016 performance periods under the OPP.

	RSUs

	The activity for the three months ended March 31, 2015, with respect to our RSUs, was as follows (awards in thousands):

		Number of			Weighted Average
		Unvested RSUs			Grant-Date Fair Value
	Balance at January 1, 2015		2,415		$	39.38
	Granted		644
	Vested		(947	)
	Forfeited		(518	)
	Balance at March 31, 2015		1,594		$	42.28

	In 2014, certain participants in our long-term incentive plan were offered an election to exchange outstanding but unvested full value awards for LTIP Units, which exchange was completed in January 2015. Included in the forfeited unvested RSUs were 0.5 million units that were forfeited upon exchange for unvested LTIP Units per this election.

	LTIP Units

	The activity for the three months ended March 31, 2015, was as follows (units in thousands):

		Number of			Weighted
		Unvested LTIP Units			Average
	Balance at January 1, 2015		113		$	41.43
	Granted		1,131
	Vested		(251	)
	Balance at March 31, 2015		993		$	43.25

	During the three months ended March 31, 2015, 0.9 million OPP LTIP Units were forfeited because the OPP performance criteria for the 2012-2014 performance period were not achieved. As of March 31, 2015, there were 1.9 million OPP LTIP Units issued with respect to the 2013-2015 and 2014-2016 performance periods. OPP LTIP Units receive quarterly cash distributions equal to one-tenth of the quarterly distributions paid on our common stock pursuant to the terms of the partnership agreement of the Operating Partnership.

	Stock Options

	We have 4.9 million stock options outstanding and exercisable at March 31, 2015, with a weighted average exercise price of $35.13. No stock options were granted in 2015.

Earnings Per Share [Abstract]
Earnings Per Common Share / Unit	11.Earnings Per Common Share / Unit

	We determine basic earnings per share/unit based on the weighted average number of shares of common stock/units outstanding during the period. We compute diluted earnings per share/unit based on the weighted average number of shares outstanding combined with the incremental weighted average effect from all outstanding potentially dilutive instruments.

	The following table sets forth the computation of our basic and diluted earnings per share/unit (in thousands, except per share/unit amounts):

	-1	The increase in shares/units between the periods is primarily due to a warrant Norges Bank Investment Management exercised in December 2014, the ATM program activity in late 2014 and early 2015 and the conversion of exchangeable debt to shares/units in March 2015.

	-2	Earnings allocated to the exchangeable Operating Partnership units not held by the Parent has been included in the numerator and exchangeable Operating Partnership units have been included in the denominator for the purpose of computing diluted earnings per share for all periods since the per share/unit amount is the same. The incremental weighted average exchangeable Operating Partnership units were 1,908 and 1,767 for the three months ended March 31, 2015 and 2014, respectively.

	-3	In March 2015, the exchangeable debt was settled primarily through the issuance of common stock. The adjustment in 2015 assumes the exchange occurred on January 1, 2015.

	-4	Total weighted average potentially dilutive stock awards were 7,391 for the three months ended March 31, 2015. Total weighted average dilutive stock awards and warrants outstanding were 15,546 for the three months ended March 31, 2014. Total weighted average potentially dilutive shares/units from exchangeable debt outstanding were 8,812 and 11,879 for the three months ended March 31, 2015 and 2014, respectively. Total weighted average potentially dilutive limited partnership units outstanding were 1,885 and 1,949 for the three months ended March 31, 2015 and 2014, respectively.

	Derivative Financial Instruments



	In the normal course of business, our operations are exposed to global market risks, including the effect of changes in foreign currency exchange rates and interest rates. To manage these risks, we may enter into various derivative contracts, such as foreign currency contracts to manage foreign currency exposure, and interest rate swaps to manage the effect of interest rate fluctuations. We do not use derivative financial instruments for trading or speculative purposes. All of our derivative financial instruments are customized derivative transactions and are not exchange-traded. Management reviews our hedging program, derivative positions and overall risk management strategy on a regular basis. We only enter into transactions that we believe will be highly effective at offsetting the underlying risk. There have been no significant changes in our policy or strategy from what was previously disclosed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2014.

	Foreign Currency

	We primarily manage our foreign currency exposure by borrowing in the currencies in which we invest. In certain circumstances, we may also borrow debt in a currency that is not the same functional currency of the borrowing entity to offset the translation and economic exposures related to our net investment in international subsidiaries. To mitigate the impact to our earnings from the fluctuations in exchange rates, we may designate the debt as a non-derivative financial instrument hedge. We also hedge our investments in certain international subsidiaries using foreign currency derivative contracts (net investment hedges) to offset the translation and economic exposures related to our investments in these subsidiaries by locking in a forward exchange rate at the inception of the hedge. We measure the effectiveness of our net investment hedges and our non-derivative financial instrument hedges by using the changes in forward exchange rates. Under this method, we report all changes in fair value of the non-derivative financial instrument and net investment hedges in equity in the foreign currency translation component of Accumulated Other Comprehensive Loss (“AOCI”) in the Consolidated Balance Sheets. These amounts offset the translation adjustments on the underlying net assets of our foreign investments, which we also record in AOCI. We recognize ineffectiveness, if any, in earnings at the time the ineffectiveness occurred. We did not record any ineffectiveness on our foreign currency derivative contracts during the three months ended March 31, 2015 and 2014.

	We may use foreign currency option contracts, including puts, calls and collars to mitigate foreign currency exchange rate risk associated with the translation of our projected net operating income of our international subsidiaries, principally in Europe and Japan. A collar contract combines put and call options into one contract with the purchase of a foreign currency put option, combined with the sale of a foreign currency call option such that there is no cash outlay at execution. This strategy effectively locks in a range around the rate at which net operating earnings of our international subsidiaries will be translated into U.S. dollars. Foreign currency option contracts are not designated as hedges as they do not meet hedge accounting requirements. Changes in the fair value of derivatives not designated in hedging relationships are recorded directly in earnings within the line item Foreign Currency and Derivative Gains (Losses) and Related Amortization, Net in the Consolidated Statements of Operations.

	Interest Rate

	Our interest rate risk management strategy is to limit the impact of future interest rate changes on earnings and cash flows as well as to stabilize interest expense and manage our exposure to interest rate movements. We may enter into interest rate swap agreements that allow us to receive variable-rate amounts from a counterparty in exchange for us making fixed-rate payments over the life of the agreement. The effective portion of the gain or loss on the derivative is reported as a component of AOCI in the Consolidated Balance Sheets, and reclassified to Interest Expense in the Consolidated Statements of Operations over the corresponding period of the hedged item. Ineffectiveness, if any, is recognized in Interest Expense at the time the ineffectiveness occurred.

	-1	During the three months ended March 31, 2015, we exercised six options and recognized a net gain of approximately $2.2 million in Foreign Currency and Derivative Gains (Losses) and Related Amortization, Net in the Consolidated Statements of Operations.

	-2	Included in our British pounds sterling denominated option contracts are eight forward contracts to sell British pounds sterling and buy euros. These forwards have a notional amount of £47.0 million (€62.8 million) and were reported above using a weighted average exchange rate of 1.11 U.S. dollars to the euro.

	-1	As discussed above, the foreign currency options are not designated as hedges. We recognized gains of $20.1 million in Foreign Currency and Derivative Gains and (Losses) and Related Amortization, Net in the Consolidated Statements of Operations from the change in value of our outstanding foreign currency options for the three months ended March 31, 2015.

	The change in Other Comprehensive Income (Loss) in the Consolidated Statements of Comprehensive Income (Loss) during the periods presented is due to the translation upon consolidation of the financial statements into U.S. dollars of our consolidated subsidiaries whose functional currency is not the U.S. dollar for which we recorded losses of $517.6 million and gains of $17.6 million, respectively, for the three months ended March 31, 2015 and 2014. It also includes the change in fair value for the effective portion of our derivative and non-derivative instruments. The following table presents the gains and losses associated with the change in fair value for the effective portion of our derivative and non-derivative instruments included in Other Comprehensive Income (Loss) (in thousands):

		Three Months Ended

Total gain (loss) on derivative and non-derivative instruments		$	397,101			$	(23,551	)

-1	This includes losses of $6.9 million for the three months ended March 31, 2014, upon the settlement of net investment hedges. No net investment hedges were settled in 2015.
-2	The amounts reclassified to interest expense for the three months ended March 31, 2015 and 2014, respectively, were not considered significant. We do not expect the amounts to be reclassified to interest expense for the next 12 months to be significant.

-3	At March 31, 2015 and December 31, 2014, we had €2.4 billion ($2.6 billion) and €2.5 billion ($3.0 billion) of debt, net of accrued interest, respectively, designated as non-derivative financial instrument hedges of our net investment in international subsidiaries. We had €102.0 million ($109.8 million) and €97.6 million ($118.5 million) of debt, respectively, that was not designated as a non-derivative financial instrument hedge at March 31, 2015 and December 31, 2014. We recognized unrealized gains of $15.4 million in Foreign Currency and Derivative Gains (Losses) and Related Amortization, Net in the Consolidated Statements of Operations on the unhedged portion or our debt during the three months ended March 31, 2015. We did not recognize any gain or loss during the three months ended March 31, 2014.

Fair Value Measurements

We have estimated the fair value of our financial instruments using available market information and valuation methodologies we believe to be appropriate for these purposes. Considerable judgment and a high degree of subjectivity are involved in developing these estimates and, accordingly, they are not necessarily indicative of amounts that we would realize upon disposition.

Fair Value Measurements on a Recurring Basis

At March 31, 2015 and December 31, 2014, other than the derivatives discussed above and in Note 7, we did not have any significant financial assets or financial liabilities that are measured at fair value on a recurring basis in the Consolidated Financial Statements. We determined the fair value of our derivative instruments using widely accepted valuation techniques including discounted cash flow analysis on the expected cash flows of each derivative. This analysis reflects the contractual terms of the derivatives, including the period to maturity, and uses observable market-based inputs, including interest rate curves, foreign exchange rates, and implied volatilities. We determined the fair values of our interest rate swaps using the market standard methodology of netting the discounted future fixed cash receipts or payments and the discounted expected variable cash payments. We based the variable cash payments on an expectation of future interest rates, or forward curves, derived from observable market interest rate curves. We based the fair values of our net investment hedges upon the change in the spot rate at the end of the period as compared to the strike price at inception.

We incorporate credit valuation adjustments to appropriately reflect both our nonperformance risk and the respective counterparty’s nonperformance risk in the fair value measurements. In adjusting the fair value of our derivative contracts for the effect of nonperformance risk, we have considered the impact of netting and any applicable credit enhancements, such as collateral postings, thresholds, mutual puts and guarantees.

We have determined that the majority of the inputs used to value our derivatives fall within Level 2 of the fair value hierarchy. Although the credit valuation adjustments associated with our derivatives utilize Level 3 inputs, such as estimates of current credit spreads to evaluate the likelihood of default by us and our counterparties, we assessed the significance of the impact of the credit valuation adjustments on the overall valuation of our derivative positions and have determined that the credit valuation adjustments are not significant to the overall valuation of our derivatives. As a result, all of our derivatives held at March 31, 2015 and December 31, 2014, were classified as Level 2 of the fair value hierarchy.

Fair Value Measurements on Non-Recurring Basis

Assets measured at fair value on a non-recurring basis in the Consolidated Financial Statements consist of real estate assets and investments in and advances to unconsolidated entities that were subject to impairment charges. There were no assets that met these criteria at March 31, 2015 or December 31, 2014.

Fair Value of Financial Instruments

At March 31, 2015 and December 31, 2014, our carrying amounts of certain financial instruments, including cash and cash equivalents, restricted cash, accounts and notes receivable, accounts payable and accrued expenses were representative of their fair values due to the short-term nature of these instruments.

At March 31, 2015 and December 31, 2014, we estimated the fair value of our senior notes and exchangeable senior notes based upon quoted market prices for the same (Level 1) or similar (Level 2) issues when current quoted market prices are available, the fair value of our Credit Facilities and term loans by discounting the future cash flows using rates and borrowing spreads currently available to us (Level 3), and the fair value of our secured mortgage debt and assessment bonds that do not have current quoted market prices available by discounting the future cash flows using rates currently available to us for debt with similar terms and maturities (Level 3). The differences in the fair value of our debt from the carrying value in the table below are the result of differences in interest rates and/or borrowing spreads that were available to us at March 31, 2015 and December 31, 2014, as compared with those in effect when the debt was issued or acquired, including reduced borrowing spreads due to our improved credit ratings. The senior notes and many of the issues 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.

The following table reflects the carrying amounts and estimated fair values of our debt (in thousands):

Business Segments	Mar. 31, 2015
Segment Reporting [Abstract]
Business Segments	13.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 represents the ownership of industrial operating properties and is the main source of our revenue and earnings. We collect rent from our customers through operating leases, including reimbursements for the majority of our operating costs. Each operating property is considered to be an individual operating segment having similar economic characteristics that are combined within the reportable segment based upon geographic location. Our Real Estate Operations segment also includes development, re-development and acquisition activities that lead to rental operations. We develop, re-develop and acquire industrial properties primarily in global and regional markets to meet our customers’ needs. Within this line of business, we capitalize on: (i) the land that we currently own; (ii) the development expertise of our local teams; (iii) our global customer relationships; and (iv) the demand for high-quality distribution facilities. Land held for development, properties currently under development and land we own and lease to customers under ground leases are also included in this segment.

	·	Strategic Capital. This represents the management of unconsolidated co-investment ventures. We invest with partners and investors through our ventures, both private and public. We tailor industrial portfolios to investors’ specific needs and deploy capital with a focus on larger, ventures with longer duration and open-ended funds with leading global institutions. These private and public vehicles provide capital for distinct geographies across our global platform. We hold a significant ownership interest in these ventures; we believe this aligns our interests with those of our partners. We generate strategic capital revenues from our unconsolidated co-investment ventures through asset management and property management services and we earn additional revenues from leasing, acquisition, construction, development and disposition services provided. Depending on the structure of the venture and the returns provided to our partners, we also earn revenues through promotes during the life of a venture or upon liquidation. Each unconsolidated co-investment venture we manage is considered to be an individual operating segment having similar economic characteristics that are combined within the reportable segment based upon geographic location.

	Reconciliations are presented below for: (i) each reportable business segment’s revenue from external customers to Total Revenues in the Consolidated Statements of Operations; (ii) each reportable business segment’s net operating income from external customers to Earnings before Income Taxes in the Consolidated Statements of Operations; and (iii) each reportable business segment’s assets to Total Assets in the Consolidated Balance Sheets. Our chief operating decision makers rely primarily on net operating income and similar measures to make decisions about allocating resources and assessing segment performance. The applicable components of Total Revenues, Earnings before Income Taxes and Total Assets are allocated to each reportable business segment’s revenues, net operating income and assets. Items that are not directly assignable to a segment, such as certain corporate income and expenses, are reflected as reconciling items. The following reconciliations are presented in thousands:

Subsequent Events	On April 17, 2015, we signed purchase agreements to acquire the real estate assets and operating platform of KTR Capital Partners and its affiliates for approximately $5.9 billion. The portfolio includes 322 operating properties aggregating 60 million square feet, 3.6 million square feet of properties under development and land parcels that will support an estimated potential build out of 6.8 million square feet. The properties will be acquired by our consolidated co-investment venture USLV, in which we own 55%. The purchase price includes the assumption of approximately $700 million of secured mortgage debt and the issuance of up to $230 million of common limited partnership units in the Operating Partnership. The transaction is anticipated to close during the second quarter of 2015.

General (Policies)	Mar. 31, 2015
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”). Through the Operating Partnership, we are engaged in the ownership, acquisition, development and operation of industrial properties in global and regional markets throughout the Americas, Europe and Asia. Our current business strategy is comprised of two operating business segments: Real Estate Operations and Strategic Capital. Our Real Estate Operations segment represents the ownership of industrial properties. Our Strategic Capital segment represents the management of co-investment ventures and other unconsolidated entities. See Note 13 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, 2015, the Parent owned an approximate 99.62% common general partnership interest in the Operating Partnership, and 100% of the preferred units in the Operating Partnership. The remaining approximate 0.38% common limited partnership interests are owned by non-affiliated investors and certain current and former directors and officers of the Parent. As the sole general partner of the Operating Partnership, the Parent has full, exclusive and complete responsibility and discretion in the day-to-day management and control of the Operating Partnership.

	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. Since 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	Basis of Presentation. The accompanying Consolidated Financial Statements are prepared in accordance with United States 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 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 the 2014 Consolidated Financial Statements as previously filed with the SEC on Form 10-K and other public information.
Recent Accounting Pronouncements	Recent Accounting Pronouncements. In April 2015, the Financial Accounting Standards Board (the “FASB”) issued an accounting standard update that requires the presentation of debt issuance costs in the balance sheet as a deduction from the carrying amount of the related debt liability instead of a deferred charge. It is effective for annual reporting periods beginning after December 15, 2015, but early adoption is permitted. At March 31, 2015, we had $50.1 million of debt issuance costs in Other Assets in the Consolidated Balance Sheets that would be subject to the reclassification.

	In February 2015, the FASB issued an accounting standard update that amends the consolidation requirements in existing GAAP. Under the update, all entities, including limited partnerships and similar legal entities, are now within the scope of consolidation guidance, unless a scope exception applies. The presumption that a general partner controls a limited partnership has been eliminated. In addition, fees paid to decision makers that meet certain conditions no longer cause the decision makers to consolidate variable interest entities (“VIEs”). It is effective for annual reporting periods beginning after December 15, 2015, but early adoption is permitted and allows for either a full retrospective or a modified retrospective adoption approach. We are currently evaluating the impact the adoption of this standard will have on the Consolidated Financial Statements.

	In May 2014, the FASB issued an accounting standard update 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. Under the model, a company will identify the contract, identify any separate performance obligations in the contract, determine the transaction price, allocate the transaction price and recognize revenue when the performance obligation is satisfied. In April 2015, the FASB proposed deferring the effective date by one year to December 15, 2017, for annual reporting periods beginning after that date. The FASB also proposed permitting early adoption of the standard, but not before the original effective date of December 15, 2016. We are currently evaluating the impact the adoption of this standard will have on the Consolidated Financial Statements.

	-1	The increase in shares/units between the periods is primarily due to a warrant Norges Bank Investment Management exercised in December 2014, the ATM program activity in late 2014 and early 2015 and the conversion of exchangeable debt to shares/units in March 2015.

	-2	Earnings allocated to the exchangeable Operating Partnership units not held by the Parent has been included in the numerator and exchangeable Operating Partnership units have been included in the denominator for the purpose of computing diluted earnings per share for all periods since the per share/unit amount is the same. The incremental weighted average exchangeable Operating Partnership units were 1,908 and 1,767 for the three months ended March 31, 2015 and 2014, respectively.

	-3	In March 2015, the exchangeable debt was settled primarily through the issuance of common stock. The adjustment in 2015 assumes the exchange occurred on January 1, 2015.

	-4	Total weighted average potentially dilutive stock awards were 7,391 for the three months ended March 31, 2015. Total weighted average dilutive stock awards and warrants outstanding were 15,546 for the three months ended March 31, 2014. Total weighted average potentially dilutive shares/units from exchangeable debt outstanding were 8,812 and 11,879 for the three months ended March 31, 2015 and 2014, respectively. Total weighted average potentially dilutive limited partnership units outstanding were 1,885 and 1,949 for the three months ended March 31, 2015 and 2014, respectively.

[1]	The difference between our ownership interest of the venturebs equity and our investment balance results principally from three types of transactions: (i) deferring a portion of the gains we recognize from a contribution of a property to the venture; (ii) recording additional costs associated with our investment in the venture; and (iii) advances to the venture.
[2]	Represents our weighted average ownership interest in all co-investment ventures based on each entitybs contribution to total assets, before depreciation, net of other liabilities.
[3]	We formed and invested in FIBRA Prologis, a Mexican REIT, in June 2014. In connection with the transaction, we concluded our unconsolidated co-investment venture in Mexico. As discussed in Note 2, we began consolidating NAIF in October 2014.
[4]	At March 31, 2015 and December 31, 2014, we had receivables from Nippon Prologis REIT, Inc. (bNPRb) of $85.5 million and $85.9 million, respectively, related to customer security deposits that are made through a leasing company owned by Prologis that pertain to properties owned by NPR. There is a corresponding payable to NPRbs customers in Other Liabilities in the Consolidated Balance Sheets.
