	Business. Prologis, Inc. (the “REIT”) 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 (“Internal Revenue Code”), 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 the controlling interest in 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 includes two reportable business segments: Real Estate Operations and Investment Management. Our Real Estate Operations segment represents the long-term ownership of industrial properties. Our Investment Management segment represents the long-term management of co-investment 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 REIT and the Operating Partnership. The terms “the Company,” “Prologis,” “we,” “our” or “us” means the REIT and Operating Partnership collectively.
	For each share of common stock or preferred stock the REIT issues, the Operating Partnership issues a corresponding common or preferred partnership unit, as applicable, to the REIT in exchange for the contribution of the proceeds from the stock issuance. As of March 31, 2014, the REIT owned an approximate 99.65% common general partnership interest in the Operating Partnership, and 100% of the preferred units. The remaining approximate 0.35% common limited partnership interests are 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. The REIT does not have significant assets other than its investment in the Operating Partnership and therefore, the assets and liabilities of the REIT and the Operating Partnership are the same on their respective financial statements.
	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, 2013, 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 2013, have been reclassified to conform to the 2014 financial statement presentation.
	Recent Accounting Pronouncements. In April 2014, the FASB issued an accounting standard update that changed the criteria for classifying and reporting discontinued operations while enhancing disclosures. Under the new guidance, only disposals of a component of an entity, or a group of components of an entity, representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have, or will have, a major effect on the organization’s operations and financial results. Examples of disposals that may meet the new criteria include a disposal of a major geographic area, a major line of business, or a major equity method investment. In addition, the new guidance requires additional disclosures about discontinued operations and the disposal of an individually significant component of an entity that does not meet the criteria for discontinued operations. We early adopted this standard prospectively for all disposals subsequent to January 1, 2014. Prior to adoption, the results of operations for real estate properties sold or held for sale during the reported periods were shown under Discontinued Operations on the Consolidated Statements of Operations (see Note 4). Going forward, we expect the majority of our dispositions will not qualify as discontinued operations and the results will be presented in Income from Continuing Operations.
	In March 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update on the accounting for currency translation adjustment (“CTA”) when a parent sells or transfers part of its ownership interest in a foreign entity. When a company sells a subsidiary or group of assets that constitute a business while maintaining ownership of the foreign entity in which those assets or subsidiary reside, a complete or substantially complete liquidation of the foreign entity is required in order for a parent entity to release CTA to earnings. However, for a company that sells all or part of its ownership interest in a foreign entity, CTA is released upon the loss of a controlling financial interest in a consolidated foreign entity or partial sale of an equity method investment in a foreign entity. For step acquisitions, the CTA associated with the previous equity-method investment is fully released when control is obtained and consolidation occurs. We adopted this standard as of January 1, 2014, and it did not have, and we do not expect it to have, a material impact on the Consolidated Financial Statements.

	Acquisitions of Unconsolidated Co-Investment Ventures
	On August 6, 2013, we concluded the unconsolidated co-investment venture Prologis North American Industrial Fund III. The venture sold 73 properties to a third party and we subsequently acquired our partner’s 80% ownership interest in the venture. The allocation of net assets acquired was $519.2 million in real estate assets and $22.0 million of net other assets. While the current allocation of the purchase price is substantially complete, the valuation of the real estate properties is being finalized. We do not expect future revisions, if any, to have a significant impact on our financial position or results of operations.
	On October 2, 2013, we acquired our partner’s 78.4% interest in the unconsolidated co-investment venture Prologis SGP Mexico and concluded the venture. The allocation of net assets acquired was $409.5 million in real estate assets and $4.0 million of net other assets and $158.4 million in debt. While the current allocation of the purchase price is substantially complete, the valuation of the real estate properties is being finalized. We do not expect future revisions, if any, to have a significant impact on our financial position or results of operations.
	The impact of the results in 2013 for the properties acquired in these acquisitions was not significant.

	Summary of Investments
	We have investments in entities through a variety of ventures. We co-invest in entities that own multiple properties with strategic capital investors and provide asset and property management services to these entities. We refer to these entities as co-investment ventures. Our ownership interest in these entities range from 15-55%. These entities may be consolidated or unconsolidated, depending on the structure, our partner’s rights and participation 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 7 for more detail regarding our consolidated investments.
	We also have other ventures, generally with one partner and that we do not manage. We refer to our investments in the entities accounted for on 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,

	Unconsolidated co-investment ventures		$	4,513,180		$	4,250,015
	Other ventures			174,742			180,224
	Totals		$	4,687,922		$	4,430,239
	Unconsolidated Co-Investment Ventures
	As of March 31, 2014, we had investments in and managed unconsolidated co-investment ventures that own portfolios of operating industrial properties and may also develop properties. We account for our investments in these ventures under the equity method of accounting and, therefore, we record our share of each venture’s net earnings or loss as Earnings from Unconsolidated Entities, Net in the Consolidated Statements of Operations. We earn fees for the management services we provide to these ventures. These fees are recognized as earned and may include property and asset management fees or transactional fees for leasing, acquisition, construction, financing, legal and tax services. We may also earn incentive returns or promotes based on the third party investor returns over time. We report these fees and incentives as Investment Management Income in the Consolidated Statements of Operations. In addition, we may earn fees for services provided to develop a building within these ventures and those fees are reflected as Development Management and Other Income in the Consolidated Statements of Operations.
	Summarized information regarding the amounts we recognize in the Consolidated Statements of Operations from our investments in the unconsolidated co-investment ventures is as follows (in thousands):

-1	We have had significant activity with our unconsolidated co-investment ventures in 2013.

There is a corresponding payable to NPR’s customers in Other Liabilities in the Consolidated Balance Sheets. As of December 31, 2013, we had receivables from Prologis European Logistics Partners Sàrl (“PELP”) for remaining sale proceeds of $35.5 million which were received in the first quarter of 2014. The remaining amounts generally represent current balances for services provided by us to the co-investment ventures.
-3	As of March 31, 2014 and December 31, 2013, we did not guarantee any third party debt of our co-investment ventures.
-4	This amount is recorded as a reduction to our investment and represents the gains that were deferred when we contributed a property to a venture due to our continuing ownership in the property.
-5	During the first quarter of 2013, one venture in the Americas recorded net gains of $21.1 million from the disposition of two properties.
In April 2014, we acquired a partner’s 5.6% ownership interest in the Prologis North American Industrial Fund for $83.5 million and now own 28.7% of the venture.
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 contributions of properties to these ventures through the remaining commitment period and we may make additional cash investments in these ventures.

	We consolidate several entities in which we do not own 100% of the common equity. In certain partnerships, the units of the entity are exchangeable into our common stock.
	If we contribute a property to a consolidated co-investment venture, the property is still reflected in the Consolidated Financial Statements, but due to our ownership of less than 100%, there is an increase in noncontrolling interest related to the contributed properties that represents the portion of the ownership attributable to our partners and the difference between cash received and historical cost is reflected as an adjustment to Additional Paid in Capital with no gain or loss recognized.
	In January 2014, we closed on a U.S. co-investment venture, Prologis U.S. Logistics Venture (“USLV”), in which we hold a 55% equity ownership interest. The venture is consolidated for accounting purposes due to the structure and voting rights of the venture. At closing, the venture acquired from us a portfolio of 66 operating properties aggregating 12.8 million square feet for an aggregate purchase price of $1.0 billion.
	The noncontrolling interests of the REIT include the noncontrolling interests presented for the Operating Partnership, as well as the common limited partnership units in the Operating Partnership that are not owned by the REIT. As of March 31, 2014, the REIT owned 99.65% common general partnership units in the Operating Partnership.
	The following is a summary of the noncontrolling interests and the consolidated entity’s total investment in real estate and debt at March 31, 2014 and December 31, 2013 (dollars in thousands):

	Outperformance Plan
	We grant awards in the form of points under our Outperformance Plan (“OPP”) corresponding to three-year performance periods. As of March 31, 2014, all awards were equity classified. At the end of the applicable performance period, if the performance criteria are met, the participants’ points will be paid in the form of common stock of the REIT or units of the Operating Partnership. The fair value of the awards are measured as of the grant date and amortized over the performance period.
	We granted points on February 13, 2014, with a fair value of $23.1 million as of the date of the grant using a Monte Carlo valuation model that assumed a risk free interest rate of 0.67% and an expected volatility of 46% for Prologis and 30% for the index of selected peer companies. Such points related to a three-year performance period that began on January 1, 2014, and will end on December 31, 2016. We also granted points in 2012 (three-year performance period will end on December 31, 2014) and 2013 (three-year performance period will end on December 31, 2015).
	We recognized $6.9 million and $7.8 million of compensation expense related to our outstanding OPP awards during the three months ended March 31, 2014 and 2013, respectively.

	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):

Derivative Instruments And Hedging Activities Disclosure [Abstract]	'

	10	Financial Instruments and Fair Value Measurements
	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. The majority of our derivative financial instruments are customized derivative transactions and are not exchange-traded. 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, 2013.
	Foreign Currency
	We hedge the net assets of 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 by using the changes in forward exchange rates because this method reflects our risk management strategies, the economics of those strategies in the financial statements and better manages interest rate differentials between different countries. Under this method, all changes in fair value of the forward currency derivative contracts designated as net investment hedges are reported in equity in the foreign currency translation component of Accumulated Other Comprehensive Income (Loss) in the Consolidated Balance Sheets (“AOCI”) and offsets translation adjustments on the underlying net assets of our foreign investments, which are also recorded in AOCI. Ineffectiveness, if any, is recognized in earnings.
	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 the exchange rate, we may designate the debt as a non-derivative financial instrument hedge. We measure our effectiveness in the same manner as our net investment hedges described above. As a result, the change in the value of this debt upon translation is recorded in the foreign currency translation component of AOCI to offset the foreign currency fluctuations related to the net investment in our subsidiaries with the same functional currency as the debt.
	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. Losses on a derivative representing hedge ineffectiveness, if any, are recognized in Interest Expense at the time the ineffectiveness occurred.
	Summary of Activity
	The following table summarizes the activity in our derivative instruments for the three months ended March 31, (in millions):
			2014					2013
			Foreign			Interest Rate		Foreign			Interest Rate
			Currency			Swaps (2)		Currency			Swaps (3)

	Notional amounts at March 31,		$	1,620.00		$	71	$	640.1		$	84.6
	-1	To hedge a portion of our investment in Europe at a fixed euro rate in U.S. dollars, we entered into two foreign currency contracts that expired in March with an aggregate notional amount of €345.9 million ($470.0 million using the weighted average forward rate of 1.36) and four foreign currency contracts that will expire in April 2014 with an aggregate notional amount of €414.5 million ($570.0 million using the weighted average forward rate of 1.38). As of March 31, 2014, we had 11 contracts with an aggregate notional amount of €1.0 billion ($1.4 billion using the weighted average forward rate of 1.35) and three contracts with an aggregate notional amount of ¥24.1billion ($250.0 million using the weighted average forward rate of 96.54).
	-2	We currently have one interest rate swap contract that matures in May 2017.
	-3	During the three months ended March 31, 2013, we settled or contributed contracts in connection with the formation of our new co-investment ventures in Europe and Japan.
	As discussed in Note 6, we issued €700 million ($959.4 million) of debt in February 2014. This debt was issued by the Operating Partnership, which is a U.S. dollar functional entity, and designated as a non-derivative financial instrument hedge. As of March 31, 2014 and December 31, 2013, we had €1.4 billion ($1.9 billion) and €700 million ($1.0 billion) of debt designated as non-derivative financial instrument hedges on our net investment in international subsidiaries, respectively. Amounts included in AOCI in the Consolidated Balance Sheets at March 31, 2014 and December 31, 2013, were losses of $20.4 million and $14.9 million, respectively.
	All derivatives are recognized at fair value in the Consolidated Balance Sheets and are within the line items Other Assets or Accounts Payable and Accrued Expenses, as applicable. Changes in the fair value of derivatives that are designated and qualify as cash flow hedges and hedges of net investments in foreign operations are recorded as accumulated gains (losses) in AOCI in the Consolidated Balance Sheets. The following table presents the fair value of our derivative instruments (in thousands):
			March 31, 2014								December 31, 2013
			Asset			Liability		AOCI			Asset			Liability		AOCI
	Net investment hedges—euro denominated		$	407		$	38,042	$	(35,334	)	$	137		$	30,302	$	(21,705	)

	During the three months ended March 31, 2014, we did not record any ineffectiveness on our derivative contracts. During the three months ended March 31, 2013, we had no significant hedge ineffectiveness. In addition, the effective portion of the gain or loss on the interest rate swaps reclassified to interest expense was not considered significant for the first quarter of 2014, and is not expected to be significant for the next 12 months. In the first quarter 2013, the effective portion reclassified to interest expense was $2.3 million.
	The following table presents gains (losses) from the change in fair value for the effective portion of our derivative and non-derivative instruments included in Other Comprehensive Income (Loss) in the Consolidated Statements of Comprehensive Income (Loss) for the three months ended March 31, (in thousands):
			2014			2013
	Derivative net investment hedges (1)		$	(16,914	)	$	34,724
	Non-derivative net investment hedges			(5,530	)		—
	Interest rate swap hedges			(1,107	)		12,511
	Total derivatives		$	(23,551	)	$	47,235
	-1	This includes losses of $6.9 million and gains of $5.4 million in 2014 and 2013, respectively, upon the settlement of net investment hedges.
	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, 2014 and December 31, 2013, other than the derivatives discussed above and in Note 6, we do not have any significant financial assets or financial liabilities that are measured at fair value on a recurring basis in the Consolidated Financial Statements. The fair value of our derivative instruments were determined 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. The fair values of our interest rate swaps are determined using the market standard methodology of netting the discounted future fixed cash receipts or payments and the discounted expected variable cash payments. The variable cash payments are based on an expectation of future interest rates, or forward curves, derived from observable market interest rate curves. The fair values of our net investment hedges are based 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 as of March 31, 2014 and December 31, 2013, 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, 2014 and December 31, 2013.
	Fair Value of Financial Instruments
	At March 31, 2014 and December 31, 2013, 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, 2014 and December 31, 2013, the fair value of our senior notes and exchangeable senior notes has been estimated 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 has been estimated 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 has been estimated 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, 2014 and December 31, 2013, as compared with those in effect when the debt was issued or acquired. 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):
			March 31, 2014					December 31, 2013
			Carrying Value			Fair Value		Carrying Value			Fair Value
	Credit Facilities		$	119,466		$	119,711	$	725,483		$	725,679

Business Segments	'
	11	Business Segments
	Our current business strategy includes two operating segments: Real Estate Operations and Investment Management. We generate revenues, earnings, net operating income and cash flows through our segments, as follows:
		•		Real Estate Operations—This represents the direct long-term ownership of industrial operating properties and is the primary source of our revenue and earnings. We collect rent from our customers under operating leases, including reimbursements for the vast 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. 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 personnel; (iii) our global customer relationships; and (iv) the demand for high quality distribution facilities in key markets. 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.
		•		Investment Management—This represents the long-term 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, long duration ventures and open ended funds with leading global institutions. These private and public vehicles source strategic capital for distinct geographies across our global platform. We hold an ownership interest in these ventures and believe our significant ownership in each of our ventures provides a strong alignment of interests with our partners. We generate investment management revenues from our unconsolidated co-investment ventures by providing asset management and property management services. We may earn revenues through additional services provided such as leasing, acquisition, construction, development, disposition, legal and tax services. Depending on the structure of the venture and the returns provided to our partners, we may also earn revenues through incentive returns or promotes during the life of a venture or upon liquidation. Each entity 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:

Accounting Policies [Abstract]	'
Business	'
	Business. Prologis, Inc. (the “REIT”) 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 (“Internal Revenue Code”), 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 the controlling interest in 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 includes two reportable business segments: Real Estate Operations and Investment Management. Our Real Estate Operations segment represents the long-term ownership of industrial properties. Our Investment Management segment represents the long-term management of co-investment 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 REIT and the Operating Partnership. The terms “the Company,” “Prologis,” “we,” “our” or “us” means the REIT and Operating Partnership collectively.
	For each share of common stock or preferred stock the REIT issues, the Operating Partnership issues a corresponding common or preferred partnership unit, as applicable, to the REIT in exchange for the contribution of the proceeds from the stock issuance. As of March 31, 2014, the REIT owned an approximate 99.65% common general partnership interest in the Operating Partnership, and 100% of the preferred units. The remaining approximate 0.35% common limited partnership interests are 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. The REIT does not have significant assets other than its investment in the Operating Partnership and 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, 2013, 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 2013, have been reclassified to conform to the 2014 financial statement presentation.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements. In April 2014, the FASB issued an accounting standard update that changed the criteria for classifying and reporting discontinued operations while enhancing disclosures. Under the new guidance, only disposals of a component of an entity, or a group of components of an entity, representing a strategic shift in operations should be presented as discontinued operations. Those strategic shifts should have, or will have, a major effect on the organization’s operations and financial results. Examples of disposals that may meet the new criteria include a disposal of a major geographic area, a major line of business, or a major equity method investment. In addition, the new guidance requires additional disclosures about discontinued operations and the disposal of an individually significant component of an entity that does not meet the criteria for discontinued operations. We early adopted this standard prospectively for all disposals subsequent to January 1, 2014. Prior to adoption, the results of operations for real estate properties sold or held for sale during the reported periods were shown under Discontinued Operations on the Consolidated Statements of Operations (see Note 4). Going forward, we expect the majority of our dispositions will not qualify as discontinued operations and the results will be presented in Income from Continuing Operations.
	In March 2013, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update on the accounting for currency translation adjustment (“CTA”) when a parent sells or transfers part of its ownership interest in a foreign entity. When a company sells a subsidiary or group of assets that constitute a business while maintaining ownership of the foreign entity in which those assets or subsidiary reside, a complete or substantially complete liquidation of the foreign entity is required in order for a parent entity to release CTA to earnings. However, for a company that sells all or part of its ownership interest in a foreign entity, CTA is released upon the loss of a controlling financial interest in a consolidated foreign entity or partial sale of an equity method investment in a foreign entity. For step acquisitions, the CTA associated with the previous equity-method investment is fully released when control is obtained and consolidation occurs. We adopted this standard as of January 1, 2014, and it did not have, and we do not expect it to have, a material impact on the Consolidated Financial Statements.
