Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION	ORGANIZATION Readers of this Quarterly Report should refer to the Company's (as defined below) audited consolidated financial statements for the year ended December 31, 2016 which are included in the Company's Annual Report on Form 10-K (our "Annual Report") for the fiscal year ended December 31, 2016 (Commission File No. 1-34948), as certain footnote disclosures which would substantially duplicate those contained in our Annual Report have been omitted from this Quarterly Report. In the opinion of management, all adjustments necessary for a fair presentation (which include only normal recurring adjustments) have been included in this Quarterly Report. Capitalized terms used, but not defined in this Quarterly Report, have the same meanings as in our Annual Report. General GGP Inc. ("GGP" or the "Company"), a Delaware corporation, was organized in July 2010 and is a self-administered and self-managed real estate investment trust, referred to as a "REIT". Effective January 27, 2017, the Company changed its name from General Growth Properties, Inc. to GGP Inc. In these notes, the terms "we," "us" and "our" refer to GGP and its subsidiaries. GGP, through its subsidiaries and affiliates, is an owner and operator of retail properties. As of June 30, 2017 , we are the owner, either entirely or with joint venture partners, of 126 retail properties. Substantially all of our business is conducted through GGP Operating Partnership, LP ("GGPOP"), GGP Nimbus, LP ("GGPN") and GGP Limited Partnership ("GGPLP", and together with GGPN and GGPOP, the "Operating Partnerships"), subsidiaries of GGP. The Operating Partnerships own an interest in the properties that are part of the consolidated financial statements of GGP. As of June 30, 2017 , GGP held approximately a 99% common equity ownership (without giving effect to the potential conversion of the Preferred Units and LTIP Units as defined below) of the Operating Partnerships, while the remaining 1% was held by limited partners and certain previous contributors of properties to the Operating Partnerships or their predecessors. GGPOP is the general partner of, and owns a 1.5% equity interest in GGPN and GGPLP. GGPOP has common units of limited partnership ("Common Units"), which are redeemable for cash or, at our option, shares of GGP common stock. It also has preferred units of limited partnership interest ("Preferred Units"), of which, certain Preferred Units can be converted into Common Units and then redeemed for cash or, at our option, shares of GGP common stock ( Note 9 ). GGPOP also has full value long term incentive plan units and appreciation only long term incentive plan units (collectively "LTIP Units"), which are redeemable for cash or, at our option, shares of GGP common stock ( Note 11 ). In addition to holding ownership interests in various joint ventures, the Operating Partnerships generally conduct their operations through General Growth Management, Inc. ("GGMI"), General Growth Services, Inc. ("GGSI") and GGPLP REIT Services, LLC ("GGPRS"). GGMI and GGSI are taxable REIT subsidiaries ("TRS"s), which provide management, leasing, tenant coordination, business development, marketing, strategic partnership and other services for a majority of our Unconsolidated Real Estate Affiliates (defined below) and for substantially all of our Consolidated Properties, as defined below. GGSI also serves as a contractor to GGMI for these services. GGPRS generally provides financial, accounting, tax, legal, development, and other services to our Consolidated Properties. We refer to our ownership interests in properties in which we own a majority or controlling interest and are consolidated under accounting principles generally accepted in the United States of America ("GAAP") as the "Consolidated Properties." We also own interests in certain properties through joint venture entities in which we own a noncontrolling interest ("Unconsolidated Real Estate Affiliates") and we refer to those properties as the "Unconsolidated Properties".

Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements include the accounts of GGP, our subsidiaries and joint ventures in which we have a controlling interest. For consolidated joint ventures, the noncontrolling partner's share of the assets, liabilities and operations of the joint ventures (generally computed as the joint venture partner's ownership percentage) is included in noncontrolling interests in consolidated real estate affiliates as permanent equity of the Company. Intercompany balances and transactions have been eliminated. Noncontrolling interests are included on our Consolidated Balance Sheets related to the Common, Preferred, and LTIP Units of GGPOP and are presented either as redeemable noncontrolling interests or as noncontrolling interests in our permanent equity. E ach of the Operating Partnerships are variable interest entities as the limited partners do not have substantive kick-out rights or substantive participating rights. However, as the Company holds a majority voting interest in the Operating Partnerships, it qualifies for the exemption from providing certain of the disclosure requirements associated with variable interest entities. We operate in a single reportable segment, which includes the operation, development and management of retail and other rental properties. Our portfolio is targeted to a range of market sizes and consumer tastes. Each of our operating properties is considered a separate operating segment, as each property earns revenues and incurs expenses, individual operating results are reviewed and discrete financial information is available. The Company's chief operating decision maker is comprised of a team of several members of executive management who use Company NOI in assessing segment operating performance. We do not distinguish or group our consolidated operations based on geography, size or type for purposes of making property operating decisions. Our operating properties have similar economic characteristics and provide similar products and services to our tenants. There are no individual operating segments that are greater than 10% of combined revenue, Company NOI or combined assets. Company NOI excludes certain non-cash and non-comparable items such as straight-line rent and intangible asset and liability amortization, which are a result of our emergence, acquisition accounting and other capital contribution or restructuring events. Further, all material operations are within the United States and no customer or tenant comprises more than 10% of consolidated revenues. As a result, the Company's operating properties are aggregated into a single reportable segment. Properties Real estate assets are stated at cost less any provisions for impairments. Expenditures for significant betterments and improvements are capitalized. Maintenance and repairs are charged to expense when incurred. Construction and improvement costs incurred in connection with the development of new properties or the redevelopment of existing properties are capitalized. Real estate taxes, interest costs, and internal costs associated with leasing and development overhead incurred during construction periods are capitalized. Capitalization is based on qualified expenditures and interest rates. Capitalized real estate taxes, interest costs, and internal costs associated with leasing and development overhead are amortized over lives which are consistent with the related assets. Pre-development costs, which generally include legal and professional fees and other third-party costs directly related to the construction assets, are capitalized as part of the property being developed. In the event a development is no longer deemed to be probable of occurring, the capitalized costs are expensed (see also our impairment policies in this note below). We periodically review the estimated useful lives of our properties, and may adjust them as necessary. The estimated useful lives of our properties range from 10 - 45 years. Depreciation or amortization expense is computed using the straight-line method based upon the following estimated useful lives: Years Buildings and improvements 10 - 45 Equipment and fixtures 3 - 20 Tenant improvements Shorter of useful life or applicable lease term Acquisitions of Operating Properties ( Note 3 ) Acquisitions of properties are accounted for utilizing the acquisition method of accounting and, accordingly, the results of operations of acquired properties have been included in the results of operations from the respective dates of acquisition. Estimates of future cash flows and other valuation techniques are used to allocate the purchase price of acquired property between land, buildings and improvements, equipment, assumed debt liabilities and identifiable intangible assets and liabilities such as amounts related to in-place tenant leases, acquired above and below-market tenant and ground leases, and tenant relationships. Identifiable intangible assets and liabilities are calculated for above-market and below-market tenant and ground leases where we are either the lessor or the lessee. The difference between the contractual rental rates and our estimate of market rental rates is measured over a period equal to the remaining non-cancelable term of the leases, including significantly below-market renewal options for which exercise of the renewal option appears to be reasonably assured. The remaining term of leases with renewal options at terms significantly below market reflect the assumed exercise of such below-market renewal options and assume the amortization period would coincide with the extended lease term. The gross asset balances of the in-place value of tenant leases are included in buildings and equipment in our Consolidated Balance Sheets. Gross Asset Accumulated Amortization Net Carrying Amount As of June 30, 2017 Tenant leases: In-place value $ 270,540 $ (178,675 ) $ 91,865 As of December 31, 2016 Tenant leases: In-place value $ 306,094 $ (214,111 ) $ 91,983 The above-market tenant leases and below-market ground leases are included in prepaid expenses and other assets ( Note 14 ); the below-market tenant leases, above-market ground leases and above-market headquarters office lease are included in accounts payable and accrued expenses ( Note 15 ) in our Consolidated Balance Sheets. Amortization/accretion of all intangibles, including the intangibles in Note 14 and Note 15 , had the following effects on our income from continuing operations: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Amortization/accretion effect on continuing operations $ (16,399 ) $ (24,919 ) $ (41,318 ) $ (49,104 ) Future amortization/accretion of all intangibles, including the intangibles in Note 14 and Note 15 , is estimated to decrease results from continuing operations as follows: Year Amount 2017 Remaining $ 27,053 2018 42,090 2019 27,343 2020 19,338 2021 14,257 Marketable Securities Marketable securities are comprised of equity securities that are classified as available-for-sale. Available-for-sale securities are presented in prepaid expenses and other assets on our Consolidated Balance Sheets at fair value. Unrealized gains and losses resulting from the mark-to-market of these securities are included in other comprehensive income. Realized gains and losses are recognized in earnings only upon the sale of the securities and are recorded based on the weighted average cost of such securities. During the six months ended June 30, 2016 , we recognized gains of $13.1 million in management fees and other corporate revenues on the Consolidated Statements of Comprehensive Income from the sale of Seritage Growth Properties stock. Investments in Unconsolidated Real Estate Affiliates ( Note 5 ) We account for investments in joint ventures where we own a non-controlling joint interest using either the equity method or the cost method. If we have significant influence but not control over the investment, we utilize the equity method. If we have neither control nor significant influence, we utilize the cost method. Under the equity method, the cost of our investment is adjusted for our share of the earnings of such Unconsolidated Real Estate Affiliates from the date of acquisition, increased by our contributions and reduced by distributions received. Under the cost method, the cost of our investment is not adjusted for our share of the earnings of such Unconsolidated Real Estate Affiliates from the date of acquisition and distributions are treated as earnings when received. To determine the method of accounting for partially owned joint ventures, we evaluate the characteristics of associated entities and determine whether an entity is a variable interest entity ("VIE"). A limited partnership or other similar entity is considered a VIE unless a simple majority of limited partners (excluding limited partners that are under common control with the general partner) have substantive kick-out rights or participating rights. Accounting guidance amended the following: (i) modified the evaluation of whether limited partnerships and similar legal entities are variable interest entities ("VIEs") or voting interest entities, (ii) eliminated the presumption that a general partner should consolidate a limited partnership, (iii) affected the consolidation analysis of reporting entities that are involved with VIEs, and (iv) provided a scope exception for certain entities. If an entity is determined to be a VIE, we determine which party is the primary beneficiary by analyzing whether we have both the power to direct the entity's significant economic activities and the obligation to absorb potentially significant losses or receive potentially significant benefits. Significant judgments and assumptions inherent in this analysis include the nature of the entity's operations, future cash flow projections, the entity's financing and capital structure, and contractual relationship and terms. The adoption of the consolidation guidance did not materially impact our consolidated financial statements. Primary risks associated with our VIEs include the potential of funding the entities' debt obligations or making additional contributions to fund the entities' operations. Generally, the operating agreements with respect to our Unconsolidated Real Estate Affiliates provide that assets, liabilities and funding obligations are shared in accordance with our ownership percentages. Therefore, we generally also share in the profit and losses, cash flows and other matters relating to our Unconsolidated Real Estate Affiliates in accordance with our respective ownership percentages. Except for Retained Debt (as described in Note 5 ), differences between the carrying amount of our investment in the Unconsolidated Real Estate Affiliates and our share of the underlying equity of our Unconsolidated Real Estate Affiliates are typically amortized over lives ranging from 5 to 45 years. When cumulative distributions exceed our investment in the joint venture, the investment is reported as a liability in our consolidated financial statements. The liability is limited to our maximum potential obligation to fund contractual obligations, including recourse related to certain debt obligations. Partially owned, non-variable interest joint ventures over which we have controlling financial interest are consolidated in our consolidated financial statements. In determining if we have a controlling financial interest, we consider factors such as ownership interest, authority to make decisions, kick-out rights and substantive participating rights. Partially owned joint ventures where we do not have a controlling financial interest, but have the ability to exercise significant influence, are accounted for using the equity method. To the extent that we contribute assets to a joint venture accounted for using the equity method, our investment in the joint venture is recorded at our cost basis in the assets that were contributed to the joint venture. We will recognize gains and losses on the contribution of our real estate to joint ventures, relating solely to the outside partner's interest, to the extent the buyer is independent of the Company, the collection of the sales price is reasonably assured, and we will not be required to support the operations of the property or its related obligations to an extent greater than our proportionate interest. The combined summarized financial information of unconsolidated joint ventures is disclosed in Note 5 to the Consolidated Financial Statements. We continually analyze and assess reconsideration events, including changes in the factors mentioned above, to determine if the consolidation treatment remains appropriate. Decisions regarding consolidation of partially owned entities frequently require significant judgment by our management. Revenue Recognition and Related Matters Minimum rents are recognized on a straight-line basis over the terms of the related operating leases, including the effect of any free rent periods. Minimum rents also include lease termination income collected from tenants to allow for the tenant to vacate their space prior to their scheduled termination dates, as well as accretion related to above-market and below-market tenant leases on acquired properties and properties that were recorded at fair value at the emergence from bankruptcy. Overage rent is paid by a tenant when the tenant's sales exceed an agreed upon minimum amount and is recognized on an accrual basis once tenant sales exceed contractual tenant lease thresholds and is calculated by multiplying the sales in excess of the minimum amount by a percentage defined in the lease. Tenant recoveries are established in the leases or computed based upon a formula related to real estate taxes, insurance and other property operating expenses and are generally recognized as revenues in the period the related costs are incurred. Real estate sales are recognized whenever (1) a sale is consummated, (2) the buyer has demonstrated an adequate commitment to pay for the property, (3) our receivable is not subject to future subordination, and (4) we have transferred to the buyer the risks and rewards of ownership and do not have continuing involvement. Unless all conditions are met, recognition of all or a portion of the profit shall be postponed. We provide an allowance for doubtful accounts against the portion of accounts receivable, net including straight-line rents, which is estimated to be uncollectible. Such allowances are reviewed periodically based upon our recovery experience. Management Fees and Other Corporate Revenues Management fees and other corporate revenues primarily represent management and leasing fees, development fees, financing fees and fees for other ancillary services performed for the benefit of certain of the Unconsolidated Real Estate Affiliates. Management fees are reported at 100% of the revenue earned from the joint venture in management fees and other corporate revenues on our Consolidated Statements of Comprehensive Income. Our share of the management fee expense incurred by the Unconsolidated Real Estate Affiliates is reported within equity in income of Unconsolidated Real Estate Affiliates on our Consolidated Statements of Comprehensive Income and in property management and other costs in the Condensed Combined Statements of Income in Note 5 . The following table summarizes the management fees from affiliates and our share of the management fee expense: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Management fees from affiliates (1) $ 20,847 $ 18,917 $ 48,990 $ 39,587 Management fee expense (8,443 ) (7,812 ) (17,246 ) (15,714 ) Net management fees from affiliates $ 12,404 $ 11,105 $ 31,744 $ 23,873 (1) Excludes a $13.1 million gain recognized in management fees and other corporate revenues on the divestiture of our investment in Seritage Growth Properties during the six months ended June 30, 2016 . Impairment Operating properties We regularly review our consolidated properties for potential impairment indicators whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Impairment indicators are assessed separately for each property and include, but are not limited to, significant decreases in real estate property net operating income, significant decreases in occupancy percentage, debt maturities, changes in management's intent with respect to the properties and prevailing market conditions. If an indicator of potential impairment exists, the property is tested for recoverability by comparing its carrying amount to the estimated future undiscounted cash flows. Although the carrying amount may exceed the estimated fair value of certain properties, a real estate asset is only considered to be impaired when its carrying amount cannot be recovered through estimated future undiscounted cash flows. To the extent an impairment provision is determined to be necessary, the excess of the carrying amount of the property over its estimated fair value is expensed to operations. In addition, the impairment provision is allocated proportionately to adjust the carrying amount of the asset group. The adjusted carrying amount, which represents the new cost basis of the property, is depreciated over the remaining useful life of the property. Although we may market a property for sale, there can be no assurance that the transaction will be complete until the sale is finalized. However, GAAP requires us to utilize the Company's expected holding period of our properties when assessing recoverability. If we cannot recover the carrying value of these properties within the planned holding period, we will estimate the fair values of the assets and record impairment charges for properties when the estimated fair value is less than their carrying value. Impairment indicators for pre-development costs, which are typically costs incurred during the beginning stages of a potential development and construction in progress, are assessed by project and include, but are not limited to, significant changes in the Company's plans with respect to the project, significant changes in projected completion dates, tenant demand, anticipated revenues or cash flows, development costs, market factors and sustainability of development projects. Impairment charges are recorded in the Consolidated Statements of Comprehensive Income when the carrying value of a property is not recoverable and it exceeds the estimated fair value of the property, which can occur in accounting periods preceding disposition and/or in the period of disposition. During the three months ended June 30, 2016 , we recorded a $4.1 million impairment charge on our Consolidated Statements of Comprehensive Income related to one operating property. During the period, we received a bona fide purchase offer for the property which was less than its carrying value. During the six months ended June 30, 2016 , we recorded a $44.8 million impairment charge on our Consolidated Statements of Comprehensive Income related to three operating properties. During the period, we received bona fide purchase offers for two properties which were less than their respective carrying values. The other property had non-recourse debt that matured during 2016 and exceeded the fair value of the operating property. This property was transferred to a special servicer during 2016 and conveyed to the lender in full satisfaction of the debt during the six months ended June 30, 2017 . No provisions for impairment were recognized for the three and six months ended June 30, 2017 . Changes in economic and operating conditions that occur subsequent to our review of recoverability of our properties could impact the assumptions used in that assessment and could result in future impairment if assumptions regarding those properties differ from actual results. Investment in Unconsolidated Real Estate Affiliates A series of operating losses of an investee or other factors may indicate that an other-than-temporary decline in value of our investment in an Unconsolidated Real Estate Affiliate has occurred. The investment in each of the Unconsolidated Real Estate Affiliates is evaluated for valuation declines below the carrying amount. Accordingly, in addition to the property-specific impairment analysis that we performed for such joint ventures (as part of our operating property impairment process described above), we also considered whether there were other-than-temporary declines with respect to the carrying values of our Unconsolidated Real Estate Affiliates. No impairments related to our investments in Unconsolidated Real Estate Affiliates were recognized for the three and six months ended June 30, 2017 and 2016 . Changes in economic and operating conditions that occur subsequent to our review of recoverability of our investments in Unconsolidated Real Estate Affiliates could impact the assumptions used in that assessment and could result in future impairment if assumptions regarding those investments differ from actual results. Fair Value Measurements ( Note 4 ) The accounting principles for fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: • Level 1 - defined as observable inputs such as quoted prices for identical assets or liabilities in active markets; • Level 2 - defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and • Level 3 - defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Note 4 includes a discussion of properties measured at fair value on a non-recurring basis using Level 2 and Level 3 inputs and the fair value of debt, which is estimated on a recurring basis using Level 2 and Level 3 inputs. Note 9 includes a discussion of certain redeemable noncontrolling interests that are measured at fair value using Level 1 inputs. Concentrations of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents. We are exposed to credit risk with respect to cash held at various financial institutions and access to our credit facility. Our credit risk exposure with regard to our cash and the $1.5 billion , including the uncommitted accordion feature, available under our credit facility is spread among a diversified group of investment grade financial institutions. We had $345.0 million outstanding and no outstanding balance under our credit facility as of June 30, 2017 and December 31, 2016 , respectively. Recently Issued Accounting Pronouncements Effective January 1, 2018, companies will be required to apply a five-step model in accounting for revenue. The core principle of the revenue model is that a company recognizes revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Lease contracts will be excluded from this revenue recognition criteria; however, the sale of real estate will be required to follow the new model. Expanded quantitative and qualitative disclosures regarding revenue recognition will be required for contracts that are subject to this pronouncement. The Company has completed a preliminary review of the potential impact of this pronouncement to determine specific areas that will be affected by the adoption of this standard. Once the new guidance setting forth principles for the recognition, measurement, presentation and disclosure of leases (discussed below) goes into effect, the new revenue standard may apply to executory costs and other components of revenue due under leases that are deemed to be non-lease components (such as common area maintenance and provision of utilities), even when the revenue for such activities is not separately stipulated in the lease. In that case, then revenue from these items previously recognized on a straight-line basis under current lease guidance would be recognized under the new revenue guidance as the related services are delivered. As a result, while the total revenue recognized over time would not differ under the new guidance, the recognition pattern would be different. The new standard can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. The company is currently evaluating the adoption method that will be used for the implementation. In February 2016, the FASB issued Accounting Standards Update ("ASU") 2016-02 which will require organizations that lease assets to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. Under ASU 2016-02, a lessee will be required to recognize assets and liabilities for leases with lease terms of more than 12 months. Lessor accounting remains substantially similar to current GAAP. However, leasing costs that are currently eligible to be capitalized as initial direct costs are limited by ASU 2016-02. In addition, disclosures of leasing activities are to be expanded to include qualitative along with specific quantitative information. For public entities, ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. ASU 2016-02 mandates a modified retrospective transition method. The Company is evaluating the potential impact of this pronouncement on its consolidated financial statements. In March 2016, the FASB issued ASU 2016-07 which eliminates the requirement for retrospective application of equity method accounting when an investment previously accounted for by another method initially qualifies for the equity method. This standard is effective for all entities for fiscal years beginning after December 15, 2016 with earlier application permitted. The adoption of this standard did not materially impact the Company's consolidated financial statements. In March 2016, the FASB issued ASU 2016-09 which simplifies the accounting for stock compensation related items such as income tax accounting, award classification, estimation of forfeitures, and cash flow presentation. The amendments in the ASU are effective for public business entities for annual periods beginning after December 15, 2016. The Company accounted for this compensation award adjustment by means of a cumulative-effect adjustment to equity as of January 1, 2017. In June 2016, the FASB issued ASU 2016-13 which changes the model for the measurement of credit losses on financial instruments. Specifically, the amendments in the ASU replace the incurred loss impairment methodology in current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. The amendments in this ASU will be effective January 1, 2020 with early adoption permitted on January 1, 2019. The Company is evaluating the potential impact of this pronouncement on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15 which provides guidance on the statement of cash flows presentation of certain transactions where diversity in practice exists. The effective date will be the first quarter of fiscal year 2019, with early adoption permitted. The ASU will be adopted using a retrospective transition approach. The Company is evaluating the potential impact of this pronouncement on its Consolidated Statements of Cash Flows. In November 2016, the FASB issued ASU 2016-18 which requires that a statement of cash flows explain the change during the reporting period in the total of cash and cash equivalents and restricted cash or restricted cash equivalents. This standard is effective for public entities for fiscal years beginning after December 15, 2017, and interim periods within those fiscal years. Early adoption is permitted, including adoption in an interim period. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. The Company is evaluating the potential impact of this pronouncement on its Consolidated Statements of Cash Flows. In January 2017, the FASB issued ASU 2017-01 which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions (or disposals) of assets or businesses. The definition of a business affects many areas of accounting including acquisitions, disposals, goodwill and consolidation. Public entities should apply the amendments in this standard to annual periods beginning after December 15, 2017, including interim periods within those periods. The Company adopted this pronouncement early in the first fiscal quarter of 2017. The adoption of this standard resulted in less real estate acquisitions qualifying as businesses and, accordingly, acquisition costs for those acquisitions that are not businesses are capitalized rather than expensed. In February 2017, the FASB issued ASU 2017-05 which clarifies the accounting for the derecognition of nonfinancial assets by eliminating the exception in current GAAP for transfers of investments in real estate entities (including equity method investments). The amendments in this update provide guidance on the accounting of partial sales of nonfinancial assets and contributions of nonfinancial assets to a joint venture or other noncontrolling investee. Once this guidance is adopted, an entity would use the guidance in the new revenue recognition standard (discussed above) to determine whether it is transferring multiple, distinct assets and would recognize a gain or loss for each distinct asset transferred. When an entity transfers nonfinancial assets included in a subsidiary and retains or receives an equity interest, it first determines whether it has retained a controlling financial interest in the subsidiary. If so, the entity does not derecognize the assets and accounts for the sale of noncontrolling interest in the subsidiary under the consolidation guidance covering decreases in ownership which would result in recognizing a gain or loss in equity. If an entity retains or receives a noncontrolling interest in the entity that owns the asset post-sale, that noncontrolling interest is considered noncash consideration and is included in the transaction price at its fair value. The retained noncontrolling interest is included at its fair value and results in an entity recognizing 100% of the gain on sale of the asset which differs from current applicable GAAP. Public entities should apply the amendments in this standard to annual periods beginning after December 15, 2017, including interim periods within those periods. Entities are required to adopt this standard in conjunction with the new revenue recognition standard which we will adopt on January 1, 2018. The adoption of this standard will result in higher gains on the sale of partial real estate interests due to recognizing 100% of the gain on sale of the partial interest and recording the retained noncontrolling interest at fair value. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. For example, estimates and assumptions have been made with respect to fair values of assets and liabilities for purposes of applying the acquisition method of accounting, the useful lives of assets, capitalization of development and leasing costs, provision for income taxes, recoverable amounts of receivables and deferred taxes, provision for loan loss, initial valuations and related amortization periods of deferred costs and intangibles, particularly with respect to acquisitions, impairment of long-lived assets, litigation related accruals and disclosures and fair value of debt. Actual results could differ from these and other estimates.

The acquisition of 605 N. Michigan Avenue on December 1, 2016 was recorded in 2016 using a preliminary estimate of the net assets acquired. Certain amounts were reclassified according to the subsequent purchase price allocation recorded during 2017. On June 30, 2016, we closed on the acquisition of a property through a joint venture located at 218 West 57th Street in New York City for $81.5 million . In connection with the acquisition, we provided a $53.0 million mortgage loan to the joint venture that bears interest at LIBOR plus 3.4% , subject to terms and conditions in the loan agreement, and matures on June 30, 2019, with two one year extension options. We own a 50% interest in the joint venture and our share of equity at closing was $15.1 million including prorated working capital. We also provided our joint venture partner with a $7.3 million loan upon closing.

On January 8, 2016, we closed on the sale of our 50% interest in Owings Mills Mall in Owings Mills, Maryland to our joint venture partner for $11.6 million . This transaction netted proceeds of approximately $11.6 million and resulted in a gain on sale of $0.6 million recognized in Unconsolidated Real Estate Affiliates - gain on investment for the six months ended June 30, 2016 . On February 27, 2015, we sold a 25% interest in Ala Moana Center in Honolulu, Hawaii for net proceeds of $907.0 million . We received $670.0 million at closing and received the remaining proceeds of $237.0 million upon completion of the redevelopment and expansion in the fourth quarter of 2016. Subsequently on April 10, 2015, we sold an additional 12.5% interest in Ala Moana Center for net proceeds of $453.5 million to another joint venture partner. We received $335.0 million at closing and received the remaining proceeds of $118.5 million upon completion of the redevelopment and expansion in the fourth quarter of 2016. As a result, our joint venture partners own a combined 37.5% economic interest in the joint venture. Upon sale of the 25% interest in Ala Moana Center and in accordance with applicable accounting standards for real estate sales with future development required, we recognized a $584.4 million gain on change in control of investment properties and other as of the closing date calculated on the percentage of the basis (real estate asset carrying value of Ala Moana Center and development costs incurred to date) as compared to the total estimated costs expected to be incurred through completion of the development. During the three months ended June 30, 2016 , we recognized an additional $5.7 million gain on change of control of investment properties and other using the percentage of completion method for the construction completed from the closing date on February 27, 2015 through June 30, 2016 . During the six months ended June 30, 2016 , we recognized an additional $12.5 million gain on change of control of investment properties and other using the percentage of completion method for the construction completed from the closing date on February 27, 2015 through June 30, 2016 . The construction is complete and the full gain was recognized as of December 31, 2016 . Upon sale of the 12.5% interest in Ala Moana Center and in accordance with applicable accounting standards for real estate sales with future development required, we recognized a $295.9 million gain in Unconsolidated Real Estate Affiliates - gain on investment as of the closing date calculated on the percentage of the basis (real estate asset carrying value of Ala Moana Center and development costs incurred to date) as compared to the total estimated costs expected to be incurred through completion of the development. During the three months ended June 30, 2016 , we recognized an additional $2.9 million gain in Unconsolidated Real Estate Affiliates - gain on investment using the percentage of completion method for the construction completed from the closing date on April 10, 2015 through June 30, 2016 . During the six months ended June 30, 2016 , we recognized an additional $6.2 million gain in Unconsolidated Real Estate Affiliates - gain on investment using the percentage of completion method for the construction completed from the closing date on April 10, 2015 through June 30, 2016 . The construction is complete and the full gain was recognized as of December 31, 2016 . We account for the 62.5% interest in the joint venture that owns Ala Moana Center under the equity method of accounting ( Note 5 ) because we share control over major decisions with the joint venture partners which resulted in the partners obtaining substantive participating rights. Prior to February 2015, Ala Moana Center was previously wholly owned by GGP and accounted for on a consolidated basis.

FAIR VALUE

FAIR VALUE	6 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE	FAIR VALUE Nonrecurring Fair Value Measurements We estimate fair value relating to impairment assessments based upon discounted cash flow and direct capitalization models that include all projected cash inflows and outflows over a specific holding period, or the negotiated sales price, if applicable. Such projected cash flows are comprised of contractual rental revenues and forecasted rental revenues and expenses based upon market conditions and expectations for growth. Capitalization rates and discount rates utilized in these models are based on a reasonable range of current market rates for each property analyzed. Based upon these inputs, we determined that our valuations of properties using a discounted cash flow or a direct capitalization model were classified within Level 3 of the fair value hierarchy. For our properties for which the estimated fair value was based on negotiated sales prices, we determined that our valuation was classified within Level 2 of the fair value hierarchy. Disclosure of Fair Value of Financial Instruments The fair values of our financial instruments approximate their carrying amount in our consolidated financial statements except for debt. Management's estimates of fair value are presented below for our debt as of June 30, 2017 and December 31, 2016 . June 30, 2017 December 31, 2016 Carrying Amount (1) Estimated Fair Value Carrying Amount (2) Estimated Fair Value Fixed-rate debt $ 10,160,336 $ 10,487,786 $ 10,441,166 $ 10,832,272 Variable-rate debt 2,335,783 2,343,870 1,989,252 1,990,458 $ 12,496,119 $ 12,831,656 $ 12,430,418 $ 12,822,730 (1) Includes net market rate adjustments of $25.7 million and deferred financing costs of $34.0 million , net. (2) Includes net market rate adjustments of $27.8 million and deferred financing costs of $40.1 million , net. The fair value of our Junior Subordinated Notes approximates their carrying amount as of June 30, 2017 and December 31, 2016 . We estimated the fair value of mortgages, notes and other loans payable using Level 2 and Level 3 inputs based on recent financing transactions, estimates of the fair value of the property that serves as collateral for such debt, historical risk premiums for loans of comparable quality, current LIBOR , U.S. treasury obligation interest rates and on the discounted estimated future cash payments to be made on such debt. The discount rates estimated reflect our judgment as to what the approximate current lending rates for loans or groups of loans with similar maturities and assume that the debt is outstanding through maturity. We have utilized market information as available or present value techniques to estimate the amounts required to be disclosed. Since such amounts are estimates that are based on limited available market information for similar transactions and do not acknowledge transfer or other repayment restrictions that may exist in specific loans, it is unlikely that the estimated fair value of any such debt could be realized by immediate settlement of the obligation.

(2) Includes management fees charged to the unconsolidated joint ventures by GGMI and GGSI. The Unconsolidated Real Estate Affiliates represent our investments in real estate joint ventures that are not consolidated. We hold interests in 25 domestic joint ventures, comprising 41 U.S. retail properties and one joint venture in Brazil. Generally, we share in the profits and losses, cash flows and other matters relating to our investments in Unconsolidated Real Estate Affiliates in accordance with our respective ownership percentages. We manage most of the properties owned by these joint ventures. On March 7, 2014, we formed a joint venture, AMX Partners, LLC ("AMX"), with Kahikolu Partners, LLC ("MKB") for the purpose of constructing a luxury residential condominium tower on a site located within the Ala Moana Shopping Center. AMX commenced recognizing revenues and cost of sales from the sale of condominiums using the percentage of completion method during 2016. In accordance with GAAP, sales of condominiums have been recognized using the percentage of completion method. Under this method, revenue is recognized when (1) construction is beyond a preliminary stage, (2) buyers are unable to receive refunds of down-payments except in the event of non-delivery, (3) a substantial percentage of the condominiums are under firm contracts, (4) collection of the sales price is reasonably assured and (5) sales proceeds and costs can be reasonably estimated. The revenue from condominium sales is calculated based on the percentage of completion, as determined by the construction contract costs incurred to date in relation to the total estimated construction costs. On March 24, 2016, Kenwood Towne Centre in Cincinnati, Ohio (property included in a joint venture of which we are 50% owner) acquired fee title to a portion of the property previously held under ground lease for a gross purchase price of $43.0 million . On September 15, 2016, joint ventures we formed with Simon Property Group and Authentic Brands Group LLC acquired Aeropostale, which is presented as a retail investment above. On June 1, 2017, we received an additional 7.3% of our joint venture partner's membership interests in Miami Design District in full satisfaction of two promissory notes for $57.6 million and $40.4 million , respectively, resulting in a total ownership of 22.3% ( Note 13 ). We determined that we had significant influence over the investment subsequent to the acquisition of the additional interest, and therefore we changed our method of accounting for this joint venture from the cost method to the equity method ( Note 2 ). Unconsolidated Mortgages, Notes and Loans Payable, and Retained Debt Our proportionate share of the mortgages, notes and loans payable of the unconsolidated joint ventures was $5.4 billion as of June 30, 2017 and December 31, 2016 , including Retained Debt (as defined below). There can be no assurance that the Unconsolidated Properties will be able to refinance or restructure such debt on acceptable terms or otherwise, or that joint venture operations or contributions by us and/or our partners will be sufficient to repay such loans. We have debt obligations in excess of our pro rata share of the debt for one of our Unconsolidated Real Estate Affiliates ("Retained Debt"). This Retained Debt represents distributed debt proceeds of the Unconsolidated Real Estate Affiliates in excess of our pro rata share of the non-recourse mortgage indebtedness. The proceeds of the Retained Debt which were distributed to us are included as a reduction in our investment in Unconsolidated Real Estate Affiliates. We had retained debt of $85.7 million at one property as of June 30, 2017 , and $86.5 million as of December 31, 2016 . We are obligated to contribute funds on an ongoing basis, as needed, to our Unconsolidated Real Estate Affiliates in amounts sufficient to pay debt service on such Retained Debt. If we do not contribute such funds, our distributions from such Unconsolidated Real Estate Affiliates, or our interest in, could be reduced to the extent of such deficiencies. As of June 30, 2017 , we do not anticipate an inability to perform on our obligations with respect to Retained Debt.

MORTGAGES, NOTES AND LOANS PAYABLE	MORTGAGES, NOTES AND LOANS PAYABLE Mortgages, notes and loans payable and the weighted-average interest rates are summarized as follows: June 30, 2017 (1) Weighted-Average Interest Rate (2) December 31, 2016 (3) Weighted-Average Interest Rate (2) Fixed-rate debt: Collateralized mortgages, notes and loans payable $ 10,160,336 4.42 % $ 10,441,166 4.44 % Total fixed-rate debt 10,160,336 4.42 % 10,441,166 4.44 % Variable-rate debt: Collateralized mortgages, notes and loans payable (4) 1,998,356 2.89 % 1,997,978 2.45 % Revolving credit facility (5) 337,427 2.41 % (8,726 ) — Total variable-rate debt 2,335,783 2.82 % 1,989,252 2.45 % Total Mortgages, notes and loans payable $ 12,496,119 4.12 % $ 12,430,418 4.12 % Junior subordinated notes $ 206,200 2.62 % $ 206,200 2.34 % (1) Includes $25.7 million of market rate adjustments and $34.0 million of deferred financing costs, net. (2) Represents the weighted-average interest rates on our contractual principal balances. (3) Includes $27.8 million of market rate adjustments and $40.1 million of deferred financing costs, net. (4) $1.4 billion of the variable-rate balance is cross-collateralized. (5) Includes deferred financing costs, which are shown as a reduction to the debt balance. See table below for the balance excluding deferred financing costs. Collateralized Mortgages, Notes and Loans Payable As of June 30, 2017 , $16.5 billion of land, buildings and equipment (before accumulated depreciation) and construction in progress have been pledged as collateral for our mortgages, notes and loans payable. Certain of these consolidated secured loans, representing $1.4 billion of debt, are cross-collateralized with other properties. Although a majority of the $12.2 billion of fixed and variable rate collateralized mortgages, notes and loans payable are non-recourse, $817.6 million of such mortgages, notes and loans payable are recourse to the Company as guarantees on secured financings. In addition, certain mortgage loans contain other credit enhancement provisions which have been provided by GGP. Certain mortgages, notes and loans payable may be prepaid but are generally subject to a prepayment penalty equal to a yield-maintenance premium, defeasance or a percentage of the loan balance. During the six months ended June 30, 2017 , we paid down a $73.4 million consolidated mortgage note at one property. The prior loan had a term-to-maturity of 0.2 years and an interest rate of 5.6% . The property subsequently replaced a property that was sold during the six months ended June 30, 2017 as collateral in our $1.4 billion loan secured by cross-collateralized mortgages on 15 properties. During the year ended December 31, 2016 , we paid down $294.4 million of consolidated mortgage notes at two properties. The prior loans had a weighted-average term-to-maturity of 1.2 years and a weighted-average interest rate of 5.3% . In conjunction with the pay down of the loans, we paid $5.4 million in transaction costs. On April 25, 2016, we amended our $1.4 billion loan secured by cross-collateralized mortgages on 15 properties. The interest rate remained consistent at LIBOR plus 1.75% , however, we were able to decrease the recourse from 100% to 50% and extend the term for three years . The loan now matures April 25, 2019, with two one year extension options. Corporate and Other Unsecured Loans We have certain unsecured debt obligations, the terms of which are described below: June 30, 2017 (1) Weighted-Average Interest Rate December 31, 2016 (2) Weighted-Average Interest Rate Unsecured debt: Revolving credit facility $ 345,000 2.41 % $ — — Total unsecured debt $ 345,000 2.41 % $ — — (1) Excludes deferred financing costs of $7.6 million in 2017 that decrease the total amount that appears outstanding in our Consolidated Balance Sheets. (2) Excludes deferred financing costs of $8.7 million in 2016 that decrease the total amount that appears outstanding in our Consolidated Balance Sheets. Our revolving credit facility (the "Facility") as amended on October 30, 2015, provides for revolving loans of up to $1.1 billion . The Facility has an uncommitted accordion feature for a total facility of up to $1.5 billion . The Facility is scheduled to mature in October 2020 and is unsecured. Borrowings under the Facility bear interest at a rate equal to LIBOR plus 130 to 190 basis points or at a base rate plus 30 to 90 basis points, which is determined by the Company's leverage level. The Facility contains certain restrictive covenants which limit material changes in the nature of our business conducted, including, but not limited to, mergers, dissolutions or liquidations, dispositions of assets, liens, incurrence of additional indebtedness, dividends, transactions with affiliates, prepayment of subordinated debt, negative pledges and changes in fiscal periods. In addition, we are required not to exceed a maximum net debt-to-value ratio, a maximum leverage ratio and a minimum net cash interest coverage ratio; we are not aware of any instances of non-compliance with such covenants as of June 30, 2017 . As of June 30, 2017 , $345.0 million was outstanding on the Facility. Junior Subordinated Notes GGP Capital Trust I, a Delaware statutory trust (the "Trust") and a wholly-owned subsidiary of GGPN, completed a private placement of $200.0 million of trust preferred securities ("TRUPS") in 2006. The Trust also issued $6.2 million of Common Securities to GGPOP. The Trust used the proceeds from the sale of the TRUPS and Common Securities to purchase $206.2 million of floating rate Junior subordinated notes of GGPOP due 2036. Distributions on the TRUPS are equal to LIBOR plus 1.45% . Distributions are cumulative and accrue from the date of original issuance. The TRUPS mature on April 30, 2036, but may be redeemed beginning on April 30, 2011 if the Trust exercises its right to redeem a like amount of Junior subordinated notes. The Junior subordinated notes bear interest at LIBOR plus 1.45% and are fully recourse to the Company. Though the Trust currently is a wholly-owned subsidiary of GGPN, we are not the primary beneficiary of the Trust and, accordingly, it is not consolidated for accounting purposes. We have recorded the Junior subordinated notes as a liability and our common equity interest in the Trust as prepaid expenses and other assets in our Consolidated Balance Sheets as of June 30, 2017 and December 31, 2016 . Letters of Credit and Surety Bonds We had outstanding letters of credit and surety bonds of $57.9 million as of June 30, 2017 and $57.8 million as of December 31, 2016 . These letters of credit and bonds were issued primarily in connection with insurance requirements, special real estate assessments and construction obligations. We are not aware of any instances of non-compliance with our financial covenants related to our mortgages, notes and loans payable as of June 30, 2017 .

Income Tax Disclosure [Abstract]
INCOME TAXES	INCOME TAXES We have elected to be taxed as a REIT under the Internal Revenue Code. We intend to maintain REIT status. To qualify as a REIT, the Company must meet a number of organizational and operational requirements, including a requirement to distribute at least 90% of our taxable ordinary income. In addition, the Company is required to meet certain asset and income tests. As a REIT, we will generally not be subject to corporate level Federal income tax on taxable income we distribute currently to our stockholders. 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 applicable alternative minimum tax) and may not be able to qualify as a REIT for four subsequent taxable years. Even if we qualify for taxation as a REIT, we may be subject to certain state and local taxes on our income or property, and to Federal income and excise taxes on our undistributed taxable income and capital gains. We are currently statutorily open to audit by the Internal Revenue Service for the years ended December 31, 2013 through 2016 and are statutorily open to audit by state taxing authorities for the years ended December 31, 2012 through 2016 . We have no unrecognized tax benefits recorded pursuant to uncertain tax positions as of June 30, 2017 .

WARRANTS
WARRANTS	WARRANTS Brookfield and certain parties who were previously members of a Brookfield investor consortium own 73,930,000 warrants (the "Warrants") to purchase common stock of GGP with an initial weighted average exercise price of $10.70 . Each Warrant was fully vested upon issuance, has a term of seven years and expires on November 9, 2017. Below is a summary of Warrants that were originally issued and are still outstanding. Initial Warrant Holder Number of Warrants Initial Exercise Price Brookfield - A 57,500,000 $ 10.75 Brookfield - B 16,430,000 10.50 73,930,000 The exercise prices of the Warrants are subject to adjustment for future dividends, stock dividends, distribution of assets, stock splits or reverse splits of our common stock or certain other events. In accordance with the agreement, these calculations adjust both the exercise price and the number of shares issuable for the originally issued 73,930,000 Warrants. During 2016 and 2017 , the number of shares issuable upon exercise of the outstanding Warrants changed as follows: Exercise Price Record Date Issuable Shares Brookfield - A Brookfield - B April 15, 2016 90,288,964 $ 8.80 $ 8.60 July 15, 2016 90,865,607 8.75 8.54 October 14, 2016 91,553,142 8.68 8.48 December 15, 2016 92,344,178 8.61 8.41 December 27, 2016 93,268,285 8.52 8.32 April 13, 2017 94,170,214 8.44 8.24 The warrant holders have the option for 57,500,000 Warrants to either full share settle (i.e. deliver cash for the exercise price of the Warrants) or net share settle at the option of the holder. The remaining 16,430,000 Warrants owned or managed by Brookfield must be net share settled. As of June 30, 2017 , the Warrants are exercisable into approximately 61 million common shares of the Company assuming net share settlement, at a weighted-average exercise price of approximately $8.40 per share. Further, as of June 30, 2017 , assuming full share settlement for all of the Warrants eligible for full share settlement and net share settlement of Warrants that must be net share settled, the Company would receive approximately $618 million in cash and would issue a total of approximately 86.8 million shares of common stock. Due to their ownership of Warrants, Brookfield's potential ownership of the Company may change as a result of payments of dividends and changes in our stock price.

Equity [Abstract]
EQUITY AND REDEEMABLE NONCONTROLLING INTERESTS	EQUITY AND REDEEMABLE NONCONTROLLING INTERESTS Allocation to Noncontrolling Interests Noncontrolling interests consists of the redeemable interests related to GGPOP Common, Preferred, and LTIP Units and the noncontrolling interest in our consolidated joint ventures. The following table reflects the activity included in the allocation to noncontrolling interests. Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Distributions to preferred GGPOP units $ (882 ) $ (2,201 ) $ (3,014 ) $ (4,403 ) Net income allocation to noncontrolling interests in GGPOP from continuing operations (common units) (676 ) (1,092 ) (1,251 ) (2,039 ) Net income allocation to noncontrolling interests in GGPOP from continuing operations (LTIP units) (299 ) (266 ) (553 ) (843 ) Net income allocated to noncontrolling interest in consolidated real estate affiliates (598 ) (397 ) (847 ) (228 ) Allocation to noncontrolling interests (2,455 ) (3,956 ) (5,665 ) (7,513 ) Other comprehensive (income) loss allocated to noncontrolling interests 320 (65 ) 315 (3 ) Comprehensive income allocated to noncontrolling interests $ (2,135 ) $ (4,021 ) $ (5,350 ) $ (7,516 ) Noncontrolling Interests The noncontrolling interest related to the Common, Preferred, and LTIP Units of GGPOP are presented either as redeemable noncontrolling interests in mezzanine equity or as noncontrolling interests in our permanent equity on our Consolidated Balance Sheets. Classification as redeemable or permanent equity is considered on a tranche-by-tranche basis and is dependent on whether we could be required, under certain events outside of our control, to redeem the securities for cash by the holders of the securities. Those tranches for which we could be required to redeem the security for cash are included in redeemable equity. If we control the decision to redeem the securities for cash, the securities are classified as permanent equity. The Common and Preferred Units of GGPOP are recorded at the greater of the carrying amount adjusted for the noncontrolling interest's share of the allocation of income or loss (and its share of other comprehensive income or loss) and dividends or their redemption value (i.e. fair value) as of each measurement date. The excess of the fair value over the carrying amount from period to period is recorded within additional paid-in capital in our Consolidated Balance Sheets. Allocation to noncontrolling interests is presented as an adjustment to net income to arrive at net income (loss) attributable to GGP Inc. The common redeemable noncontrolling interests have been recorded at fair value for all periods presented. One tranche of preferred redeemable noncontrolling interests has been recorded at fair value, while the other tranches of preferred redeemable noncontrolling interests have been recorded at carrying value. Generally, the holders of the Common Units share in any distributions by GGPOP with our common stockholders. However, the GGPOP operating partnership agreement permits distributions solely to GGP if such distributions were required to allow GGP to comply with the REIT distribution requirements or to avoid the imposition of excise tax. Under certain circumstances, the conversion rate for each Common Unit is required to be adjusted to give effect to stock distributions. If the holders had requested redemption of the Common and Preferred Units as of June 30, 2017 , the aggregate amount of cash we would have paid would have been $197.3 million and $52.5 million , respectively. GGPOP issued Preferred Units that are, or were, convertible into Common Units of GGPOP at the rates below (subject to adjustment). The holder may convert the Series D and Series E Preferred Units into Common Units of GGPOP at any time, subject to certain restrictions. The Common Units are convertible into common stock at approximately a one -to- one ratio at the current stock price. Number of Common Units for each Preferred Unit Number of Contractual Preferred Units Outstanding as of June 30, 2017 Converted Basis to Common Units Outstanding as of June 30, 2017 Conversion Price Redemption Value (1) Series B 3.00000 10 30 $ 16.66670 $ 715 Series D 1.50821 533 835 33.15188 26,637 Series E 1.29836 503 679 38.51000 25,133 $ 52,485 (1) The conversion price of Series B preferred units is lower than the GGP June 30, 2017 closing common stock price of $23.56 ; therefore, the June 30, 2017 common stock price of $23.56 , and an additional conversion rate of 1.0397624 shares is used to calculate the Series B redemption value. As of July 10, 2017, the Series B preferred unit conversion option expired and has a fixed cash redemption value of $50 per unit.

Eligible stockholders who enroll in the DRIP on or before the four th business day preceding the record date for a dividend payment will be able to have that dividend reinvested. As a result of the DRIP elections, 28,693 shares were issued during the six months ended June 30, 2017 and 13,990 shares were issued during the six months ended June 30, 2016 . Preferred Stock On February 13, 2013, we issued, in a public offering, 10,000,000 shares of 6.375% Series A Cumulative Perpetual Preferred Stock (the "Preferred Stock") at a price of $25.00 per share, resulting in net proceeds of $242.0 million after issuance costs. The Preferred Stock is recorded net of issuance costs within equity on our Consolidated Balance Sheets, and accrues a quarterly dividend at an annual rate of 6.375% . The dividend is paid in arrears in preference to dividends on our common stock, and reduces net income available to common stockholders, and therefore, earnings per share. The Preferred Stock does not have a stated maturity date but we may redeem the Preferred Stock after February 13, 2018, for $25.00 per share plus all accrued and unpaid dividends. We may redeem the Preferred Stock prior to February 13, 2018, in limited circumstances that preserve ownership limits and/or our status as a REIT, as well as during certain circumstances surrounding a change of control. Upon certain circumstances surrounding a change of control, holders of Preferred Stock may elect to convert each share of their Preferred Stock into a number of shares of GGP common stock equivalent to $25.00 plus accrued and unpaid dividends, but not to exceed a cap of 2.4679 common shares (subject to certain adjustments related to GGP common share splits, subdivisions, or combinations). Our Board of Directors declared preferred stock dividends during 2017 and 2016 as follows: Declaration Date Record Date Payment Date Dividend Per Share 2017 August 2 September 15, 2017 October 2, 2017 $ 0.3984 May 1 June 15, 2017 July 3, 2017 0.3984 January 30 March 15, 2017 April 3, 2017 0.3984 2016 October 31 December 15, 2016 January 3, 2017 $ 0.3984 August 1 September 15, 2016 October 3, 2016 0.3984 May 2 June 15, 2016 July 1, 2016 0.3984 February 1 March 15, 2016 April 1, 2016 0.3984 Accumulated Other Comprehensive Loss The following table reflects the activity of the components of accumulated other comprehensive loss for the three months ended June 30, 2017 , and 2016 : Foreign currency translation Net unrealized gains (losses) on other financial instruments Reclassification adjustment for realized gains on available-for-sale securities included in net income Total Balance at April 1, 2016 $ (77,859 ) $ 109 $ — $ (77,750 ) Other comprehensive income (loss) 8,608 11 — 8,619 Balance at June 30, 2016 $ (69,251 ) $ 120 $ — $ (69,131 ) Balance at April 1, 2017 $ (67,998 ) $ 117 $ — $ (67,881 ) Other comprehensive income (loss) (3,709 ) (3 ) — (3,712 ) Balance at June 30, 2017 $ (71,707 ) $ 114 $ — $ (71,593 ) The following table reflects the activity of the components of accumulated other comprehensive loss for the six months ended June 30, 2017 , and 2016 : Foreign currency translation Net unrealized gains (losses) on other financial instruments Reclassification adjustment for realized gains on available-for-sale securities included in net income Total Balance at January 1, 2016 $ (84,798 ) $ 100 $ 11,894 $ (72,804 ) Other comprehensive income (loss) 15,547 20 (11,894 ) 3,673 Balance at June 30, 2016 $ (69,251 ) $ 120 $ — $ (69,131 ) Balance at January 1, 2017 $ (70,560 ) $ 104 $ — $ (70,456 ) Other comprehensive income (loss) (1,147 ) 10 — (1,137 ) Balance at June 30, 2017 $ (71,707 ) $ 114 $ — $ (71,593 ) Realized gains from the sale of available-for-sale securities are included in management fees and other corporate revenues.

Earnings Per Share [Abstract]
EARNINGS PER SHARE	EARNINGS PER SHARE Basic earnings per share ("EPS") is computed by dividing net income available to common stockholders by the weighted-average number of common shares outstanding. Diluted EPS is computed after adjusting the numerator and denominator of the basic EPS computation for the effects of all potentially dilutive common shares. The dilutive effect of the Warrants and the dilutive effect of options and their equivalents (including fixed awards and nonvested stock issued under stock-based compensation plans), are computed using the "treasury" method. Information related to our EPS calculations is summarized as follows: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Numerators - Basic and Diluted: Net income 128,318 189,901 238,687 385,238 Preferred Stock dividends (3,984 ) (3,983 ) (7,968 ) (7,967 ) Allocation to noncontrolling interests (2,455 ) (3,956 ) (5,665 ) (7,513 ) Net income attributable to common stockholders $ 121,879 $ 181,962 $ 225,054 $ 369,758 Denominators: Weighted-average number of common shares outstanding - basic 882,255 883,381 883,374 883,027 Effect of dilutive securities 63,070 68,909 64,038 68,202 Weighted-average number of common shares outstanding - diluted 945,325 952,290 947,412 951,229 Anti-dilutive Securities: Effect of Preferred Units 1,544 5,415 1,544 5,415 Effect of Common Units 4,809 4,768 4,780 4,768 Effect of LTIP Units 1,879 1,775 1,885 1,759 Weighted-average number of anti-dilutive securities 8,232 11,958 8,209 11,942 For the three and six months ended June 30, 2017 and 2016 , dilutive options and dilutive shares related to the Warrants are included in the denominator of diluted EPS. Outstanding Common Units and LTIP Units have been excluded from the diluted earnings per share calculation because including such units would also require that the share of GGPOP income attributable to such units be added back to net income therefore resulting in no effect on EPS. Outstanding Preferred Units have been excluded from the diluted EPS calculation for all periods presented because including the Preferred Units would also require that the Preferred Units dividend be added back to the net income, resulting in anti-dilution. GGP owned 55,969,390 shares of treasury stock as of June 30, 2017 and 2016 . These shares are presented as common stock in treasury, at cost, on our Consolidated Balance Sheets. Additionally, GGPN holds 27,459,195 shares of stock as a result of warrants purchased during the year ended December 31, 2013. These shares are presented as issued, but not outstanding on our Consolidated Balance Sheets. Accordingly, these shares have been excluded from the calculation of EPS.

STOCK-BASED COMPENSATION PLANS

Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
STOCK-BASED COMPENSATION PLANS	STOCK-BASED COMPENSATION PLANS The GGP Inc. 2010 Equity Plan (the "Equity Plan") reserved for issuance of 4% of outstanding shares on a fully diluted basis. The Equity Plan provides for grants of nonqualified stock options, incentive stock options, stock appreciation rights, restricted stock, other stock-based awards and performance-based compensation (collectively, the "Awards"). Directors, officers and other employees of GGP and its subsidiaries and affiliates are eligible for the Awards. The Equity Plan is not subject to the Employee Retirement Income Security Act of 1974, as amended. No participant may be granted more than 4,000,000 shares, or the equivalent dollar value of such shares, in any year. Options granted under the Equity Plan will be designated as either nonqualified stock options or incentive stock options. An option granted as an incentive stock option will, to the extent it fails to qualify as an incentive stock option, be treated as a nonqualified option. The exercise price of an option may not be less than the fair value of a share of GGP's common stock on the date of grant. The term of each option will be determined prior to the date of grant, but may not exceed 10 years . On November 12, 2014, the Company's Equity Plan was amended to allow for the grant of LTIP Units to certain officers, directors, and employees of the Company as an alternative to the Company's stock options or restricted stock. LTIP Units are classes of partnership interests that under certain conditions, including vesting, are convertible by the holder into common units, which are redeemable by the holder for common shares on a one-to-one ratio (subject to adjustment for changes to GGP's capital structure) or for the cash value of such shares at the option of the Company. On February 17, 2016, the Company's Equity Plan was amended to allow for the grant of restricted stock or LTIP Units to certain officers, directors, and employees of the Company that vest based on the achievement of certain established metrics that are based on the performance of the Company. On January 1, 2017, the Company adopted ASU 2016-09, Compensation - Stock Compensation. This new guidance allowed us to make the election to account for share-based payment forfeitures when they occur versus estimating a forfeiture rate. This resulted in a cumulative effect of accounting change adjustment of $3.0 million to additional paid-in capital, noncontrolling interests related to LTIP Units and accumulated distributions in excess of earnings as of January 1, 2017. Compensation expense related to stock-based compensation plans for the three and six months ended June 30, 2017 , and 2016 is summarized in the following table in thousands: Three Months Ended June 30, Six Months Ended June 30, 2017 2016 2017 2016 Stock options - Property management and other costs $ 981 $ 1,666 $ 1,954 $ 3,153 Stock options - General and administrative 2,449 2,736 4,635 5,491 Restricted stock - Property management and other costs 1,546 767 3,058 1,308 Restricted stock - General and administrative 1,308 162 1,827 311 LTIP Units - Property management and other costs 393 379 792 588 LTIP Units - General and administrative 6,333 3,879 10,942 7,047 Total $ 13,010 $ 9,589 $ 23,208 $ 17,898 The following tables summarize stock option, LTIP Unit and restricted stock activity for the Equity Plan for GGP for the six months ended June 30, 2017 , and 2016 : 2017 2016 Shares Weighted Average Exercise Price Shares Weighted Average Exercise Price (1) Stock options Outstanding at January 1, 15,277,189 $ 17.90 18,162,700 $ 17.34 Granted — — 91,261 25.81 Exercised (406,383 ) 17.84 (1,789,201 ) 14.45 Forfeited (108,554 ) 22.75 (223,748 ) 19.80 Expired (4,107 ) 28.86 (15,608 ) 17.73 Stock options Outstanding at June 30, 14,758,145 $ 17.86 16,225,404 $ 17.67 (1) Changes to prior year weighted average exercise price is due to adjustment of the strike price for the special dividend issued in 2016. 2017 2016 Shares Weighted Average Grant Date Fair Value Shares Weighted Average Grant Date Fair Value (1) LTIP Units Outstanding at January 1, 4,345,912 $ 27.27 1,724,747 $ 29.32 Granted 553,526 25.38 2,640,963 25.89 Exercised (32,680 ) 29.15 — — Forfeited (58,894 ) 26.77 (38,862 ) 28.98 Expired — — — — LTIP Units Outstanding at June 30, 4,807,864 $ 27.05 4,326,848 $ 27.23 (1) Changes to prior year weighted average exercise price is due to adjustment of the strike price for the special dividend issued in 2016. 2017 2016 Shares Weighted Average Exercise Price Shares Weighted Average Exercise Price Restricted stock Outstanding at January 1, 476,686 $ 27.11 206,219 $ 29.16 Granted 808,448 25.30 346,873 26.18 Vested (166,852 ) 26.81 (61,586 ) 28.76 Canceled (69,761 ) 25.92 (6,936 ) 27.53 Restricted stock Outstanding at June 30, 1,048,521 25.84 484,570 27.10

The note was collateralized by AHC's equity in Miami Design District Associates, which is part of the AACMDD Group, LLC joint venture ("AACMDD"). On November 18, 2016, the maturity date of the note was amended to November 15, 2019. On June 1, 2017, AHC conveyed the collateral of the note in full satisfaction of the receivable and $2.6 million in accrued interest. On September 17, 2015, we entered into a promissory note with our joint venture partner, AHC, in which we lent AHC $40.4 million that bears interest at 6% per annum. The note was collateralized by AHC's equity in Miami Design District Associates, which is part of AACMDD. On November 18, 2016, the maturity date of the note was amended to September 17, 2019. On June 1, 2017, AHC conveyed the collateral of the note in full satisfaction of the receivable and $1.1 million in accrued interest. The two AHC promissory notes discussed above were collectively collateralized by 7.3% of our joint venture partner's membership interests in Miami Design District. On May 23, 2017, we entered into a promissory note with our joint venture partner, Bayside Equities, LLC ("Bayside Equities"), a subsidiary of AHC, in which we lent Bayside Equities $19.1 million that bears interest at 12.2% per annum. The note is collateralized by Bayside Equities' economic interest in Riverchase Galleria and the Tysons Galleria anchor box. On June 30, 2015, we entered into a promissory note with our joint venture partner MKB (defined in Note 5 ), in which we would lend MKB up to $80 million for capital calls after an initial contribution of $80 million by MKB and until the joint venture secured construction financing. This loan bears interest at LIBOR plus 6% and is secured by MKB's partnership interest in AMX, which is constructing a luxury residential condominium tower on a site located within the Ala Moana Shopping Center. As of June 30, 2017 , there was $17.1 million outstanding on this loan. Construction financing closed during the third quarter of 2015 (Note 18). Notes receivable includes $204.3 million of notes receivable from our joint venture partners related to the acquisition of 730 Fifth Avenue in New York, New York. The first note was issued for $104.3 million to our joint venture partner in the retail portion and bears interest at 8.0% compounded annually and matures on February 12, 2025. The second note was issued for $100.0 million to the joint venture partner acquiring the office portion of the property and bears interest at 9.0% subject to terms and conditions in the loan agreement and matures on April 17, 2025. As of June 30, 2017 , there was $150.0 million and $100.0 million outstanding on these loans, respectively (Note 18). Also included in notes receivable is $148.3 million and $56.9 million due from our joint venture partner related to the acquisition of the properties at 685 Fifth Avenue and 530 Fifth Avenue in New York, New York. The notes receivable bear interest at 7.5% and 9.0% respectively. Interest is compounded quarterly with accrued but unpaid interest increasing the loan balance. The notes are collateralized by our partner's ownership interest in the joint ventures. The loans mature on June 27, 2024 and June 18, 2024, respectively. On July 29, 2016, we settled a note receivable in the net amount of $78.9 million issued to Rique Empreendimentos e Participacoes Ltda. ("Rique") in exchange for approximately 18.3 million shares in Aliansce Shopping Centers, S.A. ("Aliansce"), resulting in an 11.3% ownership in Aliansce. On September 29, 2016, we sold the 18.3 million shares in Aliansce to the Canada Pension Plan Investment Board for a sales price of $84.9 million . The note receivable was issued in conjunction with our sale of Aliansce to Rique and Canada Pension Plan Investment Board on September 30, 2013. The note receivable was denominated in Brazilian Reais, bore interest at an effective interest rate of approximately 14% , was collateralized by shares of common stock in Aliansce, and required annual principal and interest payments over the term. During the six months ended June 30, 2016 , we determined, based on current information and events, that it was probable that we would be unable to collect all amounts due according to the contractual terms of the receivable. As the note receivable was a collateral dependent loan, we estimated the provision for loss based on the fair value of the market price of the Aliansce shares which served as the collateral for the loan. We recognized a $36.1 million loss on the note recorded in the provision for loan loss on the Consolidated Statements of Comprehensive Income based on the value of the collateral and included accrued interest of $7.5 million in the provision for loan loss. We recognized the impact of changes in the exchange rate on the note receivable as gain or loss on foreign currency in our Consolidated Statements of Comprehensive Income.

Accounting Policies [Abstract]
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The accompanying consolidated financial statements include the accounts of GGP, our subsidiaries and joint ventures in which we have a controlling interest. For consolidated joint ventures, the noncontrolling partner's share of the assets, liabilities and operations of the joint ventures (generally computed as the joint venture partner's ownership percentage) is included in noncontrolling interests in consolidated real estate affiliates as permanent equity of the Company. Intercompany balances and transactions have been eliminated. Noncontrolling interests are included on our Consolidated Balance Sheets related to the Common, Preferred, and LTIP Units of GGPOP and are presented either as redeemable noncontrolling interests or as noncontrolling interests in our permanent equity. E ach of the Operating Partnerships are variable interest entities as the limited partners do not have substantive kick-out rights or substantive participating rights. However, as the Company holds a majority voting interest in the Operating Partnerships, it qualifies for the exemption from providing certain of the disclosure requirements associated with variable interest entities. We operate in a single reportable segment, which includes the operation, development and management of retail and other rental properties. Our portfolio is targeted to a range of market sizes and consumer tastes. Each of our operating properties is considered a separate operating segment, as each property earns revenues and incurs expenses, individual operating results are reviewed and discrete financial information is available. The Company's chief operating decision maker is comprised of a team of several members of executive management who use Company NOI in assessing segment operating performance. We do not distinguish or group our consolidated operations based on geography, size or type for purposes of making property operating decisions. Our operating properties have similar economic characteristics and provide similar products and services to our tenants. There are no individual operating segments that are greater than 10% of combined revenue, Company NOI or combined assets. Company NOI excludes certain non-cash and non-comparable items such as straight-line rent and intangible asset and liability amortization, which are a result of our emergence, acquisition accounting and other capital contribution or restructuring events. Further, all material operations are within the United States and no customer or tenant comprises more than 10% of consolidated revenues. As a result, the Company's operating properties are aggregated into a single reportable segment.
Properties	Properties Real estate assets are stated at cost less any provisions for impairments. Expenditures for significant betterments and improvements are capitalized. Maintenance and repairs are charged to expense when incurred. Construction and improvement costs incurred in connection with the development of new properties or the redevelopment of existing properties are capitalized. Real estate taxes, interest costs, and internal costs associated with leasing and development overhead incurred during construction periods are capitalized. Capitalization is based on qualified expenditures and interest rates. Capitalized real estate taxes, interest costs, and internal costs associated with leasing and development overhead are amortized over lives which are consistent with the related assets. Pre-development costs, which generally include legal and professional fees and other third-party costs directly related to the construction assets, are capitalized as part of the property being developed. In the event a development is no longer deemed to be probable of occurring, the capitalized costs are expensed (see also our impairment policies in this note below). We periodically review the estimated useful lives of our properties, and may adjust them as necessary. The estimated useful lives of our properties range from 10 - 45 years. Depreciation or amortization expense is computed using the straight-line method based upon the following estimated useful lives: Years Buildings and improvements 10 - 45 Equipment and fixtures 3 - 20 Tenant improvements Shorter of useful life or applicable lease term
Acquisitions of Operating Properties	Acquisitions of Operating Properties ( Note 3 ) Acquisitions of properties are accounted for utilizing the acquisition method of accounting and, accordingly, the results of operations of acquired properties have been included in the results of operations from the respective dates of acquisition. Estimates of future cash flows and other valuation techniques are used to allocate the purchase price of acquired property between land, buildings and improvements, equipment, assumed debt liabilities and identifiable intangible assets and liabilities such as amounts related to in-place tenant leases, acquired above and below-market tenant and ground leases, and tenant relationships. Identifiable intangible assets and liabilities are calculated for above-market and below-market tenant and ground leases where we are either the lessor or the lessee. The difference between the contractual rental rates and our estimate of market rental rates is measured over a period equal to the remaining non-cancelable term of the leases, including significantly below-market renewal options for which exercise of the renewal option appears to be reasonably assured. The remaining term of leases with renewal options at terms significantly below market reflect the assumed exercise of such below-market renewal options and assume the amortization period would coincide with the extended lease term.
Management Fees and Other Corporate Revenues	Management Fees and Other Corporate Revenues Management fees and other corporate revenues primarily represent management and leasing fees, development fees, financing fees and fees for other ancillary services performed for the benefit of certain of the Unconsolidated Real Estate Affiliates. Management fees are reported at 100% of the revenue earned from the joint venture in management fees and other corporate revenues on our Consolidated Statements of Comprehensive Income. Our share of the management fee expense incurred by the Unconsolidated Real Estate Affiliates is reported within equity in income of Unconsolidated Real Estate Affiliates on our Consolidated Statements of Comprehensive Income and in property management and other costs in the Condensed Combined Statements of Income in Note 5 .
Impairment	Impairment Operating properties We regularly review our consolidated properties for potential impairment indicators whenever events or changes in circumstances indicate that the carrying amount may not be recoverable. Impairment indicators are assessed separately for each property and include, but are not limited to, significant decreases in real estate property net operating income, significant decreases in occupancy percentage, debt maturities, changes in management's intent with respect to the properties and prevailing market conditions. If an indicator of potential impairment exists, the property is tested for recoverability by comparing its carrying amount to the estimated future undiscounted cash flows. Although the carrying amount may exceed the estimated fair value of certain properties, a real estate asset is only considered to be impaired when its carrying amount cannot be recovered through estimated future undiscounted cash flows. To the extent an impairment provision is determined to be necessary, the excess of the carrying amount of the property over its estimated fair value is expensed to operations. In addition, the impairment provision is allocated proportionately to adjust the carrying amount of the asset group. The adjusted carrying amount, which represents the new cost basis of the property, is depreciated over the remaining useful life of the property. Although we may market a property for sale, there can be no assurance that the transaction will be complete until the sale is finalized. However, GAAP requires us to utilize the Company's expected holding period of our properties when assessing recoverability. If we cannot recover the carrying value of these properties within the planned holding period, we will estimate the fair values of the assets and record impairment charges for properties when the estimated fair value is less than their carrying value. Impairment indicators for pre-development costs, which are typically costs incurred during the beginning stages of a potential development and construction in progress, are assessed by project and include, but are not limited to, significant changes in the Company's plans with respect to the project, significant changes in projected completion dates, tenant demand, anticipated revenues or cash flows, development costs, market factors and sustainability of development projects. Impairment charges are recorded in the Consolidated Statements of Comprehensive Income when the carrying value of a property is not recoverable and it exceeds the estimated fair value of the property, which can occur in accounting periods preceding disposition and/or in the period of disposition. During the three months ended June 30, 2016 , we recorded a $4.1 million impairment charge on our Consolidated Statements of Comprehensive Income related to one operating property. During the period, we received a bona fide purchase offer for the property which was less than its carrying value. During the six months ended June 30, 2016 , we recorded a $44.8 million impairment charge on our Consolidated Statements of Comprehensive Income related to three operating properties. During the period, we received bona fide purchase offers for two properties which were less than their respective carrying values. The other property had non-recourse debt that matured during 2016 and exceeded the fair value of the operating property. This property was transferred to a special servicer during 2016 and conveyed to the lender in full satisfaction of the debt during the six months ended June 30, 2017 . No provisions for impairment were recognized for the three and six months ended June 30, 2017 . Changes in economic and operating conditions that occur subsequent to our review of recoverability of our properties could impact the assumptions used in that assessment and could result in future impairment if assumptions regarding those properties differ from actual results. Investment in Unconsolidated Real Estate Affiliates A series of operating losses of an investee or other factors may indicate that an other-than-temporary decline in value of our investment in an Unconsolidated Real Estate Affiliate has occurred. The investment in each of the Unconsolidated Real Estate Affiliates is evaluated for valuation declines below the carrying amount. Accordingly, in addition to the property-specific impairment analysis that we performed for such joint ventures (as part of our operating property impairment process described above), we also considered whether there were other-than-temporary declines with respect to the carrying values of our Unconsolidated Real Estate Affiliates. No impairments related to our investments in Unconsolidated Real Estate Affiliates were recognized for the three and six months ended June 30, 2017 and 2016 . Changes in economic and operating conditions that occur subsequent to our review of recoverability of our investments in Unconsolidated Real Estate Affiliates could impact the assumptions used in that assessment and could result in future impairment if assumptions regarding those investments differ from actual results.
Fair Value Measurements	Fair Value Measurements ( Note 4 ) The accounting principles for fair value measurements establish a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. These tiers include: • Level 1 - defined as observable inputs such as quoted prices for identical assets or liabilities in active markets; • Level 2 - defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and • Level 3 - defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. Note 4 includes a discussion of properties measured at fair value on a non-recurring basis using Level 2 and Level 3 inputs and the fair value of debt, which is estimated on a recurring basis using Level 2 and Level 3 inputs. Note 9 includes a discussion of certain redeemable noncontrolling interests that are measured at fair value using Level 1 inputs.
Concentrations of Credit Risk	Concentrations of Credit Risk Financial instruments that potentially subject us to significant concentrations of credit risk consist principally of cash and cash equivalents. We are exposed to credit risk with respect to cash held at various financial institutions and access to our credit facility.
Recently Issued Accounting Pronouncements	Recently Issued Accounting Pronouncements
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions. These estimates and assumptions affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. For example, estimates and assumptions have been made with respect to fair values of assets and liabilities for purposes of applying the acquisition method of accounting, the useful lives of assets, capitalization of development and leasing costs, provision for income taxes, recoverable amounts of receivables and deferred taxes, provision for loan loss, initial valuations and related amortization periods of deferred costs and intangibles, particularly with respect to acquisitions, impairment of long-lived assets, litigation related accruals and disclosures and fair value of debt. Actual results could differ from these and other estimates.
