	1	General

	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 Strategic Capital (formerly Investment Management). Our Real Estate Operations segment represents the long-term ownership of industrial properties. Our Strategic Capital segment represents the long-term management of co-investment ventures, both private and public. See Note 13 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 September 30, 2014, the REIT owned an approximate 99.63% common general partnership interest in the Operating Partnership, and 100% of the preferred units. The remaining approximate 0.37% 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 subsidiaries. As general partner with control of the Operating Partnership, the REIT consolidates the Operating Partnership for financial reporting purposes. The REIT’s only significant asset is 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 May 2014, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update that will use a five step model 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. The new standard will replace most existing revenue recognition in GAAP when it becomes effective for us on January 1, 2017. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

	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 10). Going forward, we expect the majority of our property dispositions will not qualify as discontinued operations and the results will be presented in Income from Continuing Operations. See Notes 3 and 4 for additional discussion.

	In March 2013, the 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, nor do we 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. The adjustments to finalize the purchase price allocation during the measurement period were not considered to be material to our financial position or results of operations. These properties were contributed in January 2014 to a consolidated venture in which we own 55% of the equity as discussed in Note 8. When we acquire a controlling interest in an equity investment, we mark our equity investment to fair value and recognize a gain or loss. In the second quarter of 2013, we also concluded an unconsolidated co-investment in Japan. We recognized a net gain of $35.9 million from these transaction for the nine months ended September 30, 2013, in Gains on Acquisitions and Dispositions of Investments in Real Estate, Net in the Consolidated Statements of Operations. The results of operations for these properties were not significant in 2013.

	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. The adjustments to finalize the purchase price allocation during the measurement period were not considered to be material to our financial position or results of operations. All properties acquired in this transaction were contributed in June 2014 to our new unconsolidated co-investment venture in Mexico, as discussed in Note 3. When we acquire a controlling interest in an equity investment, we mark our equity investment to fair value and recognize a gain or loss. We recognized a net loss of $1.1 million for this transaction during the fourth quarter of 2013. The results of operations for these properties were not significant in 2013.

In June 2014, we launched the initial public offering for FIBRA Prologis (“FIBRA”), a Mexican real estate investment trust, on the Mexican Stock Exchange. In connection with the offering, FIBRA purchased 177 properties aggregating 29.7 million square feet (12.6 million square feet from our wholly-owned portfolio, 7.6 million square feet from our consolidated co-investment venture Mexico Fondo Logistico (“AFORES”) and 9.5 million square feet from our unconsolidated co-investment venture Prologis Mexico Industrial Fund). We received 287.3 million equity units of FIBRA (priced at Ps 27.00 ($2.09)) in exchange for our combined investments and have a 45% ownership interest that we account for under the equity method. The closing price of the equity units on the Mexican Stock Exchange was Ps 28.10 ($2.08) per unit on September 30, 2014. Based on this transaction, we recognized a gain on disposition of investments in real estate of $52.5 million; current tax expense of $32.4 million; deferred tax benefit of $55.5 million; and earnings attributable to noncontrolling interest of $61.0 million, which represented the third party investors’ portion of this transaction.

	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. 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 8 for more detail regarding our consolidated investments.

	We also have other ventures, generally with one partner and that we do not manage. At September 30, 2014, our investment in these other ventures totaled $173.5 million. 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.

	Unconsolidated Co-Investment Ventures

	As of September 30, 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 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 promote fees based on the venture’s cumulative returns to the investors over time. We report these fees in Strategic Capital 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 in Development Management and Other Income in the Consolidated Statements of Operations.

	In June 2014, we earned a promote fee from Prologis Targeted U.S. Logistics Fund of $42.1 million, which was based on the venture’s cumulative returns to the investors over the prior three-year period ended June 30, 2014. Of that amount, $31.3 million represented the third party investors’ portion and is reflected in Strategic Capital Income in the Consolidated Statements of Operations. We also recognized $4.2 million of expense which is reflected in Strategic Capital Expenses in the Consolidated Statements of Operations, representing the associated cash bonus paid pursuant to the terms of the Prologis Promote Plan.



	During the nine months ended September 30, 2014, we increased our ownership of Prologis North American Industrial Fund (“NAIF”) to 63.3% by acquiring the equity units from several partners for $632.1 million. On October 20, 2014, we acquired an additional partner’s interest further increasing our ownership to 66.1% leaving one remaining limited partner, which resulted in us obtaining control over NAIF and required us to consolidate this entity in the fourth quarter of 2014.

	In 2014, we also invested our proportionate ownership interest in certain other co-investment ventures for the acquisition of properties and repayment of debt, primarily in Europe.

	As discussed in Note 3, we started a co-investment venture in Mexico in June 2014. During the first quarter of 2013, we started two co-investment ventures, one in Europe and one in Japan. We account for these ventures under the equity method and recognize strategic capital income from them.

	The amounts recognized in Strategic Capital Income and Earnings from Unconsolidated Entities, Net in the Consolidated Statements of Operations depend on the size of co-investment ventures that we manage and in which we have an equity interest. Our ownership interest in these ventures also impacts the equity in earnings we recognize. A summary of our unconsolidated co-investment ventures was as follows and represents 100% of the venture (square feet and total assets in thousands):

-1	We had significant activity with our unconsolidated co-investment ventures in 2014 and 2013. As described above, we started FIBRA in June 2014. In connection with this transaction, we concluded our unconsolidated co-investment venture in Mexico. During 2013, we concluded three co-investment ventures and we started two new co-investment ventures.
-2	During the nine months ended September 30, 2014, two ventures in the Americas recorded net gains of $16.9 million ($5.6 million was our share) from the disposition of 14 properties and FIBRA recorded acquisition costs of $37.2 million ($16.7 million was our share). During the nine months ended September 30, 2013, one venture in the Americas recorded net gains of $24.0 million from the disposition of three properties ($10.0 million was our share).
-3	As of September 30, 2014 and December 31, 2013, we had receivables from Nippon Prologis REIT, Inc. (“NPR”) of $91.7 million and $88.5 million, respectively, related to customer security deposits that are made through a leasing company owned by Prologis that pertain to properties owned by NPR. We have 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 that 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.
-4	As of September 30, 2014 and December 31, 2013, we did not guarantee any third party debt of our co-investment ventures.
-5	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.

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.

The following table is a summary of remaining equity commitments as of September 30, 2014 (in millions):

	-1	The interest rates presented represent the effective interest rates (including amortization of the non-cash premiums or discounts).
	-2	Included in the outstanding balances are borrowings denominated in non-U.S. currency, principally: euro ($3.2 billion), Japanese yen ($0.5 billion) and British pounds sterling ($0.1 billion).

	Credit Facilities

	We have a global senior credit facility (the “Global Facility”), in which funds may be drawn in U.S. dollars, euro, Japanese yen, British pounds sterling and Canadian dollars on a revolving basis. In June 2014, the Global Facility was amended to increase the availability from $2.0 billion to $2.5 billion (subject to currency fluctuations, approximately $2.43 billion at September 30, 2014). We also have a ¥45 billion ($410.0 million at September 30, 2014) Japanese yen revolver (the “Revolver”) with availability to increase to ¥56.5 billion ($514.8 million at September 30, 2014). We refer to the Global Facility and the Revolver, collectively, as our “Credit Facilities.”

	Commitments and availability under our Credit Facilities as of September 30, 2014, were as follows (in millions):



	Aggregate lender - commitments		$	2,840.20

	Senior Notes

	During the nine months ended September 30, 2014, and through the date of this report, we issued the following senior notes (in thousands except for percentages):

	-1	This debt is denominated in euro and the exchange rate used to calculate into U.S. dollar was the effective rate at the date of the transaction.
	-2	We used the net proceeds for general corporate purposes, including to repurchase senior debt and to repay borrowings under our multi-currency senior term loan and our Global Facility.
	-3	We used the net proceeds for general corporate purposes, including the acquisition and development of properties and additional investments in our European co-investment ventures.

	During 2014, we repurchased or repaid $1.3 billion of certain of our senior notes and other debt that was scheduled to mature during 2015 through 2018 in an effort to reduce our overall borrowing rate and extend our debt maturities. This resulted in a net loss from early extinguishment of $84.8 million and $163.4 million, respectively, for the three and nine months ended September 30, 2014.

Exchangeable Senior Notes

The fair value of the embedded derivative associated with our exchangeable notes was a liability of $19.9 million and $41.0 million at September 30, 2014 and December 31, 2013, respectively. In adjusting to fair value, we recognized unrealized gains of $27.6 million and $21.2 million for the three and nine months ended September 30, 2014, respectively, and we recognized unrealized gains of $6.5 million and unrealized losses of $6.6 million for the three and nine months ended September 30, 2013, respectively, inForeign Currency and Derivative Gains (Losses) and Related Amortization, Net in the Consolidated Statements of Operations.

Term Loans

On June 19, 2014, we terminated our existing senior term loan agreement and entered into a new agreement (the “Euro Term Loan”) under which loans can be obtained in U.S. dollars, euro, Japanese yen, and British pounds sterling in an aggregate amount not to exceed €500 million ($629.2 million at September 30, 2014). We may pay down and re-borrow under the Euro Term Loan and increase the borrowings up to €1.0 billion ($1.3 billion at September 30, 2014), subject to obtaining additional lender commitments. The Euro Term Loan was fully drawn at September 30, 2014). The loan is scheduled to mature in June 2017; however, we may extend the maturity date twice, by one year each, subject to the satisfaction of certain conditions and payment of an extension fee.

In May 2014, we entered into a Japanese yen term loan (“Yen Term Loan”), under which we may obtain loans in an aggregate amount not to exceed ¥40.9 billion ($372.8 million at September 30, 2014). We may increase the borrowings to ¥51.1 billion ($465.6 million at September 30, 2014), subject to obtaining additional lender commitments. The Yen Term Loan is scheduled to mature in 2021, and the interest rate is yen LIBOR plus 120 basis points. The Yen Term Loan was fully drawn at September 30, 2014.

During the second quarter of 2014, we repurchased approximately 435,300 shares and recognized a loss on preferred stock redemption of $6.5 million, which primarily represented the difference between redemption value and carrying value net of original issuance costs.

	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. However, 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. The difference between cash received and historical cost is reflected as an adjustment to Additional Paid-in Capital in the Consolidated Balance Sheets with no gain or loss recognized.
	In January 2014, we closed on a U.S. co-investment venture, Prologis U.S. Logistics Venture, 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 of the Operating Partnership, as well as the common limited partnership units in the Operating Partnership that are not owned by the REIT. As of September 30, 2014, the REIT owned 99.63% common general partnership units in the Operating Partnership.

In 2014, 62 limited partnership units were redeemed for cash. All of these outstanding limited partnership units receive quarterly cash distributions equal to the quarterly dividends paid on our common stock pursuant to the terms of the applicable partnership agreements.
	-2	In June 2014, AFORES contributed the majority of its operating properties and the balance of its secured debt to FIBRA.

Outperformance Plan

We grant awards in the form of points under our Outperformance Plan (“OPP”) corresponding to three-year performance periods. As of September 30, 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. 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 relate to a three-year performance period that began on January 1, 2014, and will end on December 31, 2016. We also granted points in 2013 (three-year performance period will end on December 31, 2015) and 2012 (three-year performance period will end on December 31, 2014).

We recognized $6.9 million and $20.8 million of compensation expense related to our outstanding OPP awards during the three and nine months ended September 30, 2014, respectively, and $5.0 million and $18.0 million during the three and nine months ended September 30, 2013, respectively.

Prologis Promote Plan

The Prologis Promote Plan (“PPP”) was modified in the third quarter of 2014 to allow certain participants the option to receive LTIP Units in lieu of RSUs. Under the PPP, the awards may be settled in cash or RSUs (or LTIP Units if elected), which vest over a specified period of time. Each LTIP Unit represents a partnership interest in the Operating Partnership and, after vesting, may be convertible into a common unit in the Operating Partnership after the satisfaction of certain conditions. This modification did not trigger additional compensation expense. A compensation pool was funded in August 2014 associated with an incentive fee earned from one of our co-investment ventures. The total value of the awards in the third quarter 2014 from this compensation pool was $11.3 million, of which $4.2 million was paid in cash, approximately 57,000 RSUs were issued with a grant date fair value of $2.4 million and approximately 113,000 LTIP Units were issued with a grant date fair value of $4.7 million. The RSUs and LTIP Units vest over three years.

	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 may use foreign currency option contracts, including puts, calls and collars to mitigate foreign currency exchange rate risk associated with the projected net operating income of our international subsidiaries, primarily in Europe. Foreign currency collars mitigate foreign currency exchange rate risk associated with the projected net operating income of our international subsidiaries. This strategy includes 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. The put option contracts provide us with the option to exchange euros for U.S. dollars at a fixed exchange rate if the euro were to depreciate against the U.S. dollar, such that, if the euro were to depreciate against the U.S. dollar to predetermined levels as set by the contracts, we could exercise our options and mitigate our foreign currency exchange losses. The call option would create an obligation to exchange euros for U.S. dollars at a fixed exchange rate if the euro were to appreciate against the U.S. dollar, such that, if the euro were to appreciate against the U.S. dollar to predetermined levels as set by the contracts we would be obligated to pay out under the contract and offset our foreign currency exchange gains. 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.

	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 ofAccumulated 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 at the time the ineffectiveness occurred.

	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 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. Ineffectiveness, if any, is recognized in Interest Expense at the time the ineffectiveness occurred.

	-1	During the three and nine months ended September 30, 2014, we exercised one and two put options, respectively, and recognized a net gain of approximately $1.0 million and $1.1 million, respectively. We had five foreign currency collars outstanding at September 30, 2014.
	-2	During the third quarter of 2014, we entered into two contracts with a total notional amount of ¥40.9 billion to effectively fix the interest rate on the Yen Term Loan. See Note 6 for more information on our Yen Term Loan.
	-3	During the nine months ended September 30, 2013, we settled 12 contracts with a notional value of $319.9 million, and contributed 13 contracts with a notional value of $383.9 million related to the transfer of assets to the newly formed PELP co-investment venture. We also settled five contracts in Japan with a notional value of $526.4 million in connection with the contribution of properties to NPR.

	As discussed in Note 6, we issued €1.2 billion ($1.6 billion) of debt during the nine months ended September 30, 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 September 30, 2014 and December 31, 2013, we had €1.9 billion ($2.4 billion) and €700 million ($1.0 billion) of debt, respectively, designated as non-derivative financial instrument hedges on our net investment in international subsidiaries. Amounts included in AOCI in the Consolidated Balance Sheets for our non-derivative financial instrument hedges at September 30, 2014 and December 31, 2013, were gains of $214.6 million and losses of $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. As discussed above, 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):



		September 30, 2014											December 31, 2013
		Asset				Liability				AOCI			Asset			Liability				AOCI
Net investment hedges - euro denominated		$	16,441			$	—			$	18,565		$	137		$	30,302			$	(21,705	)

-1	As discussed above, the foreign currency options are not designated as hedges. We recognized gains of $1.1 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 collars for the three and nine months ended September 30, 2014.
-2	Items indicated by ‘- -’ are not applicable

During the three and nine months ended September 30, 2014, we did not record any ineffectiveness on our derivative contracts. During the three and nine months ended September 30, 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 all periods presented, and is not expected to be significant for the next 12 months.

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 and 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								Nine Months Ended
		September 30,								September 30,

Derivative net investment hedges (1)		$	93,502			$	(23,801	)		$	70,393		$	10,395
Interest rate swap hedges			(39	)			(821	)			(229	)		71
Our share of derivatives from unconsolidated co-investment ventures			(4,474	)			3,584				(7,555	)		21,768

Total gain (loss) on derivative and non-derivative instruments		$	293,239			$	(21,038	)		$	277,179		$	32,234



-1	This includes gains of $5.9 million and losses of $5.5 million for the three and nine months ended September 30, 2014, respectively, and a gain of $4.3 million for the nine months ended September 30, 2013, 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 September 30, 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 September 30, 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 September 30, 2014 or December 31, 2013.

Fair Value of Financial Instruments

At September 30, 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 September 30, 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 September 30, 2014 and December 31, 2013, 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):



		September 30, 2014								December 31, 2013

Segment Reporting [Abstract]	'
Business Segments	'
	13	Business Segments
	Our current business strategy includes two operating segments: Real Estate Operations and Strategic Capital (formerly 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.

		•		Strategic Capital. 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 strategic capital revenues from our unconsolidated co-investment ventures by providing asset management and property management services. We 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 promote fees 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 (Loss) 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 (Loss) 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 Strategic Capital (formerly Investment Management). Our Real Estate Operations segment represents the long-term ownership of industrial properties. Our Strategic Capital segment represents the long-term management of co-investment ventures, both private and public. See Note 13 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 September 30, 2014, the REIT owned an approximate 99.63% common general partnership interest in the Operating Partnership, and 100% of the preferred units. The remaining approximate 0.37% 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 subsidiaries. As general partner with control of the Operating Partnership, the REIT consolidates the Operating Partnership for financial reporting purposes. The REIT’s only significant asset is 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 May 2014, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update that will use a five step model 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. The new standard will replace most existing revenue recognition in GAAP when it becomes effective for us on January 1, 2017. We have not yet selected a transition method nor have we determined the effect of the standard on our ongoing financial reporting.

	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 10). Going forward, we expect the majority of our property dispositions will not qualify as discontinued operations and the results will be presented in Income from Continuing Operations. See Notes 3 and 4 for additional discussion.

	In March 2013, the 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, nor do we expect it to have, a material impact on the Consolidated Financial Statements.

Total weighted average potentially dilutive shares/units from exchangeable debt outstanding were 11,879 for all periods presented. Excluding the Operating Partnership units discussed above, total weighted average potentially dilutive limited partnership units outstanding were 1,944 and 1,950 for the three months ended September 30, 2014 and 2013, respectively, and were 1,947 and 1,426 for the nine months ended September 30, 2014 and 2013, respectively.
