Summary of Significant Accounting Policies [Abstract] |
Business of Presentation and Consolidation | Basis of Presentation and Consolidation. The accompanying consolidated financial statements are presented in our reporting currency, the U.S. dollar. All material intercompany transactions with consolidated entities have been eliminated. We consolidate all entities that are wholly owned and those in which we own less than 100% but control, as well as any variable interest entities in which we are the primary beneficiary. We evaluate our ability to control an entity and whether the entity is a variable interest entity (“VIE”) and we are the primary beneficiary through consideration of substantive terms of the arrangement to identify which enterprise has the power to direct the activities of the entity that most significantly impacts the entity’s economic performance and the obligation to absorb losses of the entity or the right to receive benefits from the entity. For entities that are not defined as variable interest entities, we first consider whether Prologis is the general partner or the limited partner (or the equivalent in such investments which are not structured as partnerships). We consolidate entities in which we are the general partner and the limited partners in such investments do not have rights which would preclude control. For entities in which we are the general partner but do not control the entity as the other partners hold substantive participating rights and/or kick-out rights, the equity method of accounting is applied. For joint ventures for which we are the limited partner, we consider factors such as ownership interest, voting control, authority to make decisions, and contractual and substantive participating rights of the partners to determine if the presumption that the general partner controls the entity is overcome. In instances where the factors indicate that we control the joint venture, we consolidate the entity.
Adjustments and Reclassifications | Adjustments and Reclassifications. Certain amounts included in the accompanying consolidated financial statements for 2010 and 2009 have been reclassified to conform to the 2011 financial statements presentation.
Use of Estimates | Use of Estimates. The accompanying consolidated financial statements 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. Although we believe the assumptions and estimates we made are reasonable and appropriate, as discussed in the applicable sections throughout these Consolidated Financial Statements, different assumptions and estimates could materially impact our reported results. The current economic environment has increased the degree of uncertainty inherent in these estimates and assumptions and future changes in market conditions could impact our future operating results.
Foreign Operations | Foreign Operations. The U.S. dollar is the functional currency for our consolidated subsidiaries and unconsolidated investees operating in the United States and Mexico and certain of our consolidated subsidiaries that operate as holding companies for foreign investments. The functional currency for our consolidated subsidiaries and unconsolidated investees operating in countries other than the United States and Mexico is the principal currency in which the entity’s assets, liabilities, income and expenses are denominated, which may be different from the local currency of the country of incorporation or the country where the entity conducts its operations. The functional currencies of our consolidated subsidiaries and unconsolidated investees generally include the Brazilian real, British pound sterling, Canadian dollar, Chinese renminbi, euro, Japanese yen, Korean won and Singapore dollar. We are parties to business transactions denominated in these and other currencies. For our consolidated subsidiaries whose functional currency is not the U.S. dollar, we translate their financial statements into U.S. dollars at the time we consolidate those subsidiaries’ financial statements. Generally, assets and liabilities are translated at the exchange rate in effect as of the balance sheet date. For the REIT, the resulting translation adjustments are included in the Accumulated Other Comprehensive Income (Loss) as a separate component of stockholders’ equity. For the Operating Partnership, these adjustments are included in Partners’ Capital. Certain balance sheet items, primarily equity and capital-related accounts, are reflected at the historical exchange rate. Income statement accounts are translated using the average exchange rate for the period and income statement accounts that represent significant non-recurring transactions are translated at the rate in effect as of the date of the transaction. We translate our share of the net earnings or losses of our unconsolidated investees whose functional currency is not the U.S. dollar at the average exchange rate for the period. We and certain of our consolidated subsidiaries have intercompany and third party debt that is not denominated in the entity’s functional currency. When the debt is remeasured against the functional currency of the entity, a gain or loss can result. The resulting adjustment is generally reflected in results of operations, unless it is intercompany debt that is deemed to be long-term in nature. For the REIT, the remeasurement of such long-term debt results in the recognition of a cumulative translation adjustment in Accumulated Other Comprehensive Income (Loss) as a separate component of stockholders’ equity. For the Operating Partnership, this adjustment is recorded in Partners’ Capital. Gains or losses are included in results of operations when transactions with a third party, denominated in a currency other than the entity’s functional currency, are settled. We are subject to foreign currency risk due to potential fluctuations in exchange rates between certain foreign currencies and the U.S. dollar. A significant change in the value of the foreign currency of one or more countries where we have a significant investment would have an effect on our reported results of operations and financial position. Although we attempt to mitigate adverse effects by borrowing under debt agreements denominated in the same functional currency as the investment and, on occasion and when deemed appropriate, through the use of derivative contracts, there can be no assurance that those attempts to mitigate foreign currency risk will be successful.
Business Combinations | Business Combinations. When we acquire a business, which includes an operating property, we record the acquisition at “full fair value”. Transaction costs related to the acquisition of a business are expensed as incurred. The transaction costs related to the acquisition of land and equity method investments continue to be capitalized, as these are not considered to be business combinations. When we acquire a business or individual operating properties, with the intention to hold the investment for the long-term, we allocate the purchase price to the various components of the acquisition based upon the fair value of each component. We estimate the following:
• the fair value of the buildings as if vacant; |  |  | — |  |  | The fair value allocated to land is generally based on relevant market data.
• the market value of above and below market leases based upon our best estimate of current market rents; |  |  | — |  |  | The value of each lease is recorded in either other assets or other liabilities, as appropriate.
• the value of costs to obtain tenants, primarily leasing commissions; |  |  | — |  |  | These costs are recorded in other assets.
• the value of debt based on quoted market rates for the same or similar issues, or by discounting future cash flows using rates currently available for debt with similar terms and maturities; |  |  | — |  |  | Any discount or premium is included in the principal amount.
• the value of any management contracts by discounting future expected cash flows under these contracts; and |  |  | — |  |  | These contracts are recorded in other assets.
• the value of all other assumed assets and liabilities based on the best information available. |  |  |  |  |  |
We amortize the acquired assets or liabilities as follows:
| • |  | Above and below market leases are charged to rental income over the average remaining estimated life of the lease.
| • |  | Leasing commissions are charged to amortization expense over the average remaining estimated life of the lease.
| • |  | Debt discount or premium is charged to interest expense using the effective interest method over the remaining term of the related debt.
| • |  | Management contracts are charged to amortization expense over the remaining term of the contract.
Goodwill represents the excess of the purchase price over the fair value of net tangible and intangible assets acquired in a business combination. A gain may be recognized to the extent the purchase price is less than the fair value of net tangible and intangible assets acquired.
Long-Lived Assets | Long-Lived Assets. Real Estate Assets. Real estate assets are carried at depreciated cost. Costs incurred in developing, renovating, rehabilitating and improving real estate assets are capitalized as part of the investment basis of the real estate assets. Costs incurred in acquiring real estate properties and making repairs and maintaining real estate assets are expensed as incurred. During the land development and construction periods of qualifying projects, we capitalize interest costs, insurance, real estate taxes and general and administrative costs of the personnel performing the development, renovation, and rehabilitation; if such costs are incremental and identifiable to a specific activity to get the asset ready for its intended use. Capitalized costs are included in the investment basis of real estate assets. When a municipal district finances costs we incur for public infrastructure improvements, we record the costs in real estate until we are reimbursed. We also capitalize costs incurred to successfully originate a lease that results directly from and are essential to acquire that lease. Leasing costs that meet the requirements for capitalization are presented as a component of other assets. The depreciable portions of real estate assets are charged to depreciation expense on a straight-line basis over their respective estimated useful lives. Depreciation commences at the earlier of stabilization (defined as 90% occupied) or one year after completion of construction. We generally use the following useful lives: 5 to 7 years for capital improvements, 10 years for standard tenant improvements, 25 years for depreciable land improvements on developed buildings, 30 years for industrial properties acquired, 40 years for office and retail properties acquired and 40 years for properties we develop. Investments that are located on tarmac, which is land owned by federal, state or local airport authorities, and subject to ground leases are depreciated over the lesser of the investment life or the contractual term of the underlying ground lease. Capitalized leasing costs are amortized over the respective lease term. Our weighted average lease term based on square feet for all leases in effect at December 31, 2011 was six years. We assess the carrying values of our respective long-lived assets, whenever events or changes in circumstances indicate that the carrying amounts of these assets may not be fully recoverable. Recoverability of the assets is measured by comparison of the carrying amount of the asset to the estimated future undiscounted cash flows. In order to review our assets for recoverability, we consider current market conditions, as well as our intent with respect to holding or disposing of the asset. Fair value is determined through various valuation techniques; including discounted cash flow models; quoted market values; and third party appraisals, where considered necessary. If our analysis indicates that the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, we recognize an impairment charge for the amount by which the carrying value exceeds the current estimated fair value of the real estate property. We estimate the future undiscounted cash flows based on our intent as follows:
(i) | for real estate properties that we intend to hold long-term, including land held for development, properties currently under development and operating buildings, recoverability is assessed based on the estimated future net rental income from operating the property and the terminal value;
(ii) | for land parcels we intend to sell, recoverability is assessed based on estimated fair value;
(iii) | for real estate properties currently under development and operating buildings we intend to sell, recoverability is assessed based on proceeds from disposition that are estimated based on future net rental income of the property and expected market capitalization rates; and
(iv) | for costs incurred related to the potential acquisition of land or development of a real estate property, recoverability is assessed based on the probability that the acquisition or development is likely to occur as of the measurement date.
The use of projected future cash flows is based on assumptions that are consistent with our estimates of future expectations and the strategic plan we use to manage our underlying business. However, assumptions and estimates about future cash flows, discount rates and capitalization rates are complex and subjective. Changes in economic and operating conditions and our ultimate investment intent that occur subsequent to our impairment analyses could impact these assumptions and result in future impairment of our real estate properties or the recognition of a gain or loss at time of disposal.
Goodwill | Goodwill. Goodwill represents the excess of the purchase price over the fair value of net tangible and intangible assets acquired in a business combination. We perform an annual impairment test for goodwill at the reporting unit level. The annual review is performed during the fourth quarter for all our reporting units. Additionally, we evaluate the recoverability of goodwill whenever events or changes in circumstances indicate that the carrying amounts of goodwill may not be fully recoverable. We use a two step approach to our goodwill impairment evaluation. The first step of the goodwill impairment test is used to identify whether there is any potential impairment. If the fair value of a reporting unit exceeds its corresponding book value, including goodwill, the goodwill of the reporting unit is not considered to be impaired and the second step of the impairment test is unnecessary. If the carrying amount of the reporting unit exceeds its fair value, the second step of the impairment test is performed. The second step requires that we compare the implied fair value of the reporting unit goodwill with the carrying amount of that goodwill to measure the amount of impairment loss, if any. Generally, we use net asset value analyses to estimate the fair value of the reporting unit where the goodwill is allocated. We estimate the current fair value of the assets and liabilities in the reporting unit through various valuation techniques; including discounted cash flow models, applying a capitalization rate to estimated net operating income of a property, quoted market values and third-party appraisals, as considered necessary. The fair value of the reporting unit also includes an enterprise value premium that we estimate a third party would be willing to pay for the particular reporting unit. The use of projected future cash flows is based on assumptions that are consistent with our estimates of future expectations and the strategic plan we use to manage our underlying business. However, assumptions and estimates about future cash flows, discount rates and capitalization rates are complex and subjective. Changes in economic and operating conditions that occur subsequent to our impairment analyses could impact these assumptions and result in future impairment of our goodwill.
Assets Held for Sale and Discontinued Operations | Assets Held for Sale and Discontinued Operations. Discontinued operations represent a component of an entity that has either been disposed of or is classified as held for sale if both the operations and cash flows of the component have been or will be eliminated from ongoing operations of the entity as a result of the disposal transaction and the entity will not have any significant continuing involvement in the operations of the component after the disposal transaction. The results of operations of a component of our business or properties that have been classified as discontinued operations are also reported as discontinued operations for all periods presented. We classify a component of our business or property as held for sale when certain criteria are met, which are in accordance with GAAP. At such time, the respective assets and liabilities are presented separately on our Consolidated Balance Sheets and depreciation is no longer recognized. Assets held for sale are reported at the lower of their carrying amount or their estimated fair value less the costs to sell the assets. Assets held for sale and properties disposed of are considered discontinued operations if sold to a third party. Properties contributed or sold to entities in which we maintain an ownership interest, act as manager and account for under the equity method are not considered discontinued operations due to our continuing involvement with the properties.
Investments in Unconsolidated Investees | Investments in Unconsolidated Investees. Our investments in certain entities are presented under the equity method. The equity method is used when we have the ability to exercise significant influence over operating and financial policies of the investee but do not have control of the investee. Under the equity method, these investments (including advances to the investee) are initially recognized in the balance sheet at our cost and are subsequently adjusted to reflect our proportionate share of net earnings or losses of the investee, distributions received, deferred gains from the contribution of properties and certain other adjustments, as appropriate. When circumstances indicate there may have been a reduction in the value of an equity investment, we evaluate the equity investment and any advances made for impairment by estimating our ability to recover our investment from based on fair value. If we determine the loss in value is other than temporary, we recognize an impairment charge to reflect the equity investment and any advances made at fair value.
Notes Receivable Backed by Real Estate | Notes Receivable Backed by Real Estate. We hold certain investments in debt securities that are backed by real estate assets. We regularly review the creditworthiness of the entities with which we hold the note agreements and reduce the notes receivable balance by estimating an allowance for amounts that may become uncollectible in the future. The notes are also evaluated individually for impairment. We consider a loan to be impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the agreement.
Cash and Cash Equivalents | Cash and Cash Equivalents. We consider all cash on hand, demand deposits with financial institutions, and short-term highly liquid investments with original maturities of three months or less to be cash equivalents. Our cash and cash equivalents are financial instruments that are exposed to concentrations of credit risk. We invest our cash with high-credit quality institutions. Cash balances may be invested in money market accounts that are not insured. We have not realized any losses in such cash investments or accounts and believe that we are not exposed to any significant credit risk.
Restricted Cash | Restricted Cash. Restricted cash consists primarily of escrows under secured mortgage agreements for taxes, insurance and certain other reserve requirements relating to the underlying collateral.
Exchangeable Debt | Exchangeable Debt. For the convertible notes we issued in 2008 and 2007, we were required to separate the accounting for the debt and equity components as we have the ability to settle the conversion of the debt and conversion spread, at our option, in cash, common stock, or a combination of cash and stock. The liability and equity components of convertible debt are accounted for separately. The value assigned to the debt component is the estimated fair value at the date of issuance of a similar bond without the conversion feature, which results in the debt being recorded at a discount. The resulting debt discount is amortized over the estimated remaining life of the debt as additional non-cash interest expense. The carrying amount of the equity component is determined by deducting the fair value of the debt component from the initial proceeds of the convertible debt instrument as a whole. Under the terms of the issuance of the 2010 convertible notes, we were required to settle the conversion by issuance of common shares and therefore this standard did not apply to these notes. In connection with the Merger and the debt exchange offer in June 2011, all issuances of our convertible notes became exchangeable notes issued by the Operating Partnership that are exchangeable into common stock of the REIT. As a result, the accounting for the exchangeable senior notes now requires us to separate the fair value of the derivative instrument (exchange feature) from the debt instrument and account for it separately as a derivative. At each reporting period, we adjust the derivative instrument to fair value with the adjustment being recorded in earnings as Foreign Currency Exchange and Derivative Gains (Losses), Net. We continue to amortize the discount over the remaining term of the exchangeable notes.
Noncontrolling Interests | Noncontrolling Interests. We recognize the noncontrolling interests in real estate partnerships that we consolidate using each noncontrolling holder’s respective share of the estimated fair value of the net assets as of the date of formation or acquisition. Noncontrolling interest that was created or assumed as a part of a business combination is recognized at fair value as of the date of the transaction. Noncontrolling interest is subsequently adjusted for additional contributions, distributions to noncontrolling holders and the noncontrolling holders’ proportionate share of the net earnings or losses of each respective entity. Certain limited partnership interests issued by us in connection with the formation of a real estate partnership and as consideration in a business combination are exchangeable into our common stock. Common stock issued upon exchange of a holder’s noncontrolling interest are accounted for at our carrying value of the surrendered noncontrolling interest.
Costs of Raising Capital | Costs of Raising Capital. Costs incurred in connection with the issuance of both common stock and preferred stock are treated as a reduction to additional paid-in capital. Costs incurred in connection with the issuance or renewal of debt are capitalized in other assets, and amortized to interest expense over the term of the related debt.
Revenue Recognition | Revenue Recognition. Rental Income. We lease our operating properties to customers under agreements that are classified as operating leases. We recognize the total minimum lease payments provided for under the leases on a straight-line basis over the lease term. Generally, under the terms of our leases, the majority of our rental expenses are recovered from our customers. We reflect amounts recovered from customers as a component of rental income in the period that the applicable expenses are incurred. A provision for possible loss is made if the collection of a receivable balance is considered doubtful. Private Capital Revenue. Private capital revenue includes revenues we earn from the management services we provide to unconsolidated investees and certain third parties. 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 provided. We may also earn promote payments based on third party investor returns over time. We recognize these fees when earned, fixed and determinable. Gains on Disposition of Real Estate. Gains on the disposition of real estate are recorded when the recognition criteria have been met, generally at the time the risks and rewards and title have transferred and we no longer have substantial continuing involvement with the real estate sold. When we contribute or sell a property to an entity in which we have an ownership interest, we do not recognize a portion of the gain realized. If a loss is realized it is recognized when known. The amount of gain not recognized, based on our ownership interest in the entity acquiring the property, is deferred by recognizing a reduction to our investment in the applicable unconsolidated investee. We adjust our proportionate share of net earnings or losses recognized in future periods to reflect the investees’ recorded depreciation expense as if it were computed on our lower basis in the contributed properties rather than on the entity’s basis. When a property that we originally contributed to a co-investment venture is disposed of to a third party, we recognize the amount of the gain we had previously deferred, along with our proportionate share of the gain recognized by the investee. During periods when our ownership interest in an investee decreases and the decrease is expected to be permanent, we recognize the amounts relating to previously deferred gains to coincide with our new ownership interest in the investee.
Rental expense | Rental Expenses. Rental expenses primarily include the cost of on-site property management personnel, utilities, repairs and maintenance, property insurance and real estate taxes.
Private Capital Expense | Private Capital Expenses. These costs include the property management expenses associated with the property-level management of the properties owned by our unconsolidated investees and the direct investment management expenses associated with the asset management of the property funds.
Stock-Based Compensation | Stock-Based Compensation. We account for stock-based compensation by measuring the cost of employee services received in exchange for an award of an equity instrument based on the fair value of the award on the grant date. We recognize the cost of the entire award on a straight-lined basis over the period during which an employee is required to provide service in exchange for the award, generally the vesting period.
Income Taxes | Income Taxes. Prologis, Inc., as the legal acquirer, commenced operations as a fully integrated real estate company in 1997, elected to be taxed as a REIT under the Internal Revenue Code, and believes the current organization and method of operation will enable the REIT to maintain its status as a REIT. Under the Internal Revenue Code, REITs are generally not required to pay federal income taxes if they distribute 100% of their taxable income and meet certain income, asset and stockholder tests. If we fail to qualify as a REIT in any taxable year, we will be subject to federal income taxes at regular corporate rates (including any alternative minimum tax) and may not be able to qualify as a REIT for the four subsequent taxable years. Even as a REIT, we may be subject to certain state and local taxes on our own income and property, and to federal income and excise taxes on our undistributed taxable income. We have elected taxable REIT subsidiary (“TRS”) status for some of our consolidated subsidiaries. This allows us to provide services that would otherwise be considered impermissible for REITs. Many of the foreign countries in which we have operations do not recognize REITs or do not accord REIT status under their respective tax laws to our entities that operate in their jurisdiction. In the United States, we are taxed in certain states in which we operate. Accordingly, we recognize income tax expense for the federal and state income taxes incurred by our TRSs, taxes incurred in certain states and foreign jurisdictions, and interest and penalties associated with our unrecognized tax benefit liabilities. We evaluate tax positions taken in the financial statements on a quarterly basis under the interpretation for accounting for uncertainty in income taxes. As a result of this evaluation, we may recognize a tax benefit from an uncertain tax position only if it is “more-likely-than-not” that the tax position will be sustained on examination by taxing authorities. Deferred income taxes are recognized in certain taxable entities. Deferred income tax is generally a function of the period’s temporary differences (items that are treated differently for tax purposes than for financial reporting purposes) and the utilization of tax net operating losses generated in prior years that had been previously recognized as deferred income tax assets. A valuation allowance for deferred income tax assets is provided if we believe all or some portion of the deferred income tax asset may not be realized. Any increase or decrease in the valuation allowance that results from a change in circumstances that causes a change in the estimated realizability of the related deferred income tax asset is included in deferred tax expense.
Financial Instruments | Financial Instruments. We may use certain types of derivative financial instruments for the purpose of managing certain foreign currency exchange rate and interest rate risk. We reflect our derivative financial instruments at fair value and record changes in the fair value of these derivatives each period in earnings, unless specific hedge accounting criteria are met. To qualify for hedge accounting treatment, generally the derivative instruments used for risk management purposes must effectively reduce the risk exposure that they are designed to hedge (primarily interest rate swaps) and, if a derivative instrument is utilized to hedge an anticipated transaction, the anticipated transaction must be probable of occurring. Derivative instruments meeting these hedging criteria are formally designated as hedges at the inception of the contract or at the redesignation process, if applicable. The unrealized gains and losses resulting from changes in fair value of an effective hedge are recorded in Accumulated Other Comprehensive Income (Loss) for the REIT and Partners’ Capital for the Operating Partnership and are amortized to earnings over the remaining term of the hedged items. The ineffective portion of a hedge, if any, is immediately recognized in earnings to the extent that the change in value of the derivative instrument does not perfectly offset the change in value of the item being hedged. We estimate the fair value of our financial instruments through a variety of methods and assumptions that are based on market conditions and risks existing at each balance sheet date. Primarily, we use quoted market prices or quotes from brokers or dealers for the same or similar instruments. These values represent a general approximation of possible value and may never actually be realized.
Fair value measurements | Fair Value Measurements. The objective of fair value is to determine the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date (the exit price). We estimate fair value for all of our assets and liabilities 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. The fair value hierarchy consists of three broad levels:
| • |  | Level 1 — Quoted prices in active markets for identical assets or liabilities that the entity has the ability to access.
| • |  | Level 2 — Observable inputs, other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets; quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are observable or can be corroborated by observable market data.
| • |  | Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets and liabilities. This includes certain pricing models, discounted cash flow methodologies and similar techniques that use significant unobservable inputs.
Environmental costs | Environmental Costs. We incur certain environmental remediation costs, including cleanup costs, consulting fees for environmental studies and investigations, monitoring costs, and legal costs relating to cleanup, litigation defense, and the pursuit of responsible third parties. Costs incurred in connection with operating properties and properties previously sold are expensed. Costs related to undeveloped land are capitalized as development costs. Costs incurred for properties to be disposed are included in the cost of the properties upon disposition. We maintain a liability for the estimated costs of environmental remediation expected to be incurred in connection with undeveloped land, operating properties and properties previously sold that we adjust as appropriate as information becomes available.
Recent Accounting Pronouncements | Recent Accounting Pronouncements. In December 2011, the Financial Accounting Standards Board (“FASB”) issued an accounting standard update that requires disclosures about offsetting and related arrangements to enable financial statements users to evaluate the effect or potential effect of netting arrangements on an entity’s financial position, including rights of setoff associated with certain financial instruments and derivative instruments. The disclosure requirements are effective for us on January 1, 2013, and we do not expect the guidance to have a material impact on our Consolidated Financial Statements. In December 2011, the FASB issued an accounting standard update to clarify the scope of current U.S. GAAP. The update clarifies that the real estate sales guidance applies to the derecognition of in-substance real estate. That is, even if the reporting entity ceases to have a controlling financial interest under the consolidation guidance, the reporting entity would continue to include the real estate, debt, and the results of the subsidiary’s operations in its consolidated financial statements until legal title to the real estate is transferred to legally satisfy the debt. This accounting standard update is effective for interim and annual periods beginning after June 15, 2012. We do not expect the guidance to impact our Consolidated Financial Statements. In September 2011, the FASB issued guidance to amend and simplify the rules related to testing goodwill for impairment. The revised guidance allows an entity to make an initial qualitative evaluation, based on the entity’s events and circumstances, to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. The results of this qualitative assessment determine whether it is necessary to perform the currently required two-step impairment test. The new guidance is effective for annual and interim goodwill impairment tests performed for fiscal years beginning after December 15, 2011. We will adopt this standard on January 1, 2012 and we do not expect the guidance to have a material impact on our Consolidated Financial Statements. In June 2011, the FASB issued an accounting standard update that eliminates the option to present components of other comprehensive income (“OCI”) as part of the changes in stockholders’ equity, and requires the presentation of components of net income and other comprehensive income either in a single continuous statement or in two separate but consecutive statements. The amendments in this standard do not change the items that must be reported in OCI, when an item of OCI must be reclassified to net income, or change the option for an entity to present components of OCI gross or net of the effect of income taxes. This accounting standard update is effective, on a retrospective basis, for interim and annual periods beginning after December 15, 2011. We will adopt this standard on January 1, 2012 and we do not expect the guidance to have a material impact on our Consolidated Financial Statements. In May 2011, the FASB issued an accounting standard update to amend the requirements in GAAP for measuring fair value and for disclosing information about fair value measurements in order to achieve further convergence with International Financial Reporting Standards. The amendments will be effective for us on January 1, 2012 and we do not expect them to have a material impact to our Consolidated Financial Statements. In December 2010, the FASB updated the accounting standard related to business combinations that requires public entities to disclose certain pro forma information about revenues and earnings of the combined entity within the notes to the financial statements. As a result of the Merger and acquisition of a controlling interest in ProLogis European Properties (“PEPR”) as described in Note 3, we are required to present pro forma information as if the business combinations occurred at the beginning of the prior annual reporting period for purposes of calculating both the current reporting period and the prior reporting period pro forma financial information. The disclosure requirements were effective for business combinations with effective dates beginning January 1, 2011. See Note 3 for our pro forma disclosures. In July 2010, the FASB issued an accounting standard update that expands existing disclosures about the credit quality of financing receivables and the related allowance for credit losses. We adopted the expanded disclosure requirements for ending balances applicable to our Notes Receivable Backed by Real Estate as of December 31, 2010. Disclosures regarding activity that occurs during the reporting period were effective beginning January 1, 2011. See Note 7 for disclosure of this activity for the year ended December 31, 2011. In January 2010, the FASB issued an accounting standard update that requires disclosures about purchases, sales, issuances and settlements in the reconciliation for Level 3 fair value measurements. The Level 3 disclosure requirements were effective for us on January 1, 2011. Since we do not have any significant financial assets or financial liabilities that are measured at fair value using Level 3 valuation techniques and inputs on a recurring basis, the adoption of this standard was not considered material.

- Definition Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed.

The disclosure may encompass important judgment as to appropriateness of principles related to recognition of revenue. The disclosure also may indicate the entity's treatment of any unearned or deferred revenue that arises from the transaction. + References Reference 1: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 235 -SubTopic 10 -Section 50 -Paragraph 1 -URI http://asc.fasb.org/extlink&oid=6367646&loc=d3e18726-107790 Reference 2: http://www.xbrl.org/2003/role/presentationRef -Publisher FASB -Name Accounting Standards Codification -Topic 605 -SubTopic 10 -Section S99 -Paragraph 1 -Subparagraph (SAB TOPIC 13.B.Q1) -URI http://asc.fasb.org/extlink&oid=6600647&loc=d3e214044-122780 Reference 3: http://www.xbrl.org/2003/role/presentationRef -Publisher AICPA -Name Accounting Principles Board Opinion (APB) -Number 22 -Paragraph 8, 12, 13 -LegacyDoc This reference is SUPERSEDED by the Accounting Standards Codification effective for interim and annual periods ending after September 15, 2009.
