Simon Property Group, Inc. and Subsidiaries

Condensed Notes to Consolidated Financial Statements

(Unaudited)

(Dollars in thousands, except share and per share amounts and where indicated in millions or billions)

1.    Organization

            Simon Property Group, Inc., or Simon Property, is a Delaware corporation that operates as a self-administered and self-managed real estate investment trust, or REIT, under the Internal Revenue Code. Simon Property Group, L.P., or the Operating Partnership, is our majority-owned partnership subsidiary that owns all of our real estate properties and other assets. In these condensed notes to the unaudited consolidated financial statements, the terms "we", "us" and "our" refer to Simon Property, the Operating Partnership, and its subsidiaries.

            We own, develop and manage retail real estate properties, which consist primarily of malls, Premium Outlets®, The Mills®, and community/lifestyle centers. As of June 30, 2012, we owned or held an interest in 325 income-producing properties in the United States, which consisted of 161 malls, 60 Premium Outlets, 70 community/lifestyle centers, 13 properties in The Mills portfolio, and 21 other shopping centers or outlet centers in 41 states and Puerto Rico. Internationally, as of June 30, 2012, we had ownership interests in eight Premium Outlets in Japan, two Premium Outlets in South Korea, one Premium Outlet in Mexico, and one Premium Outlet in Malaysia. Additionally, as of June 30, 2012, we owned a 28.9% equity stake in Klépierre SA, or Klépierre, a publicly traded, Paris-based real estate company, which owns, or has an interest in, more than 260 shopping centers located in 13 countries in Europe.

2.    Basis of Presentation

            The accompanying unaudited consolidated financial statements include the accounts of all majority-owned subsidiaries, and all significant intercompany amounts have been eliminated. Due to the seasonal nature of certain operational activities, the results for the interim period ended June 30, 2012, are not necessarily indicative of the results to be expected for the full year.

            These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and include all of the information and disclosures required by accounting principles generally accepted in the United States (GAAP) for interim reporting. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments necessary for fair presentation (including normal recurring accruals) have been included. The consolidated financial statements in this Form 10-Q should be read in conjunction with the audited consolidated financial statements and related notes contained in our 2011 Annual Report on Form 10-K.

            As of June 30, 2012, we consolidated 228 wholly-owned properties and 18 additional properties that are less than wholly-owned, but which we control or for which we are the primary beneficiary. We account for the remaining 91 properties, or the joint venture properties, as well as our investment in Klépierre, using the equity method of accounting, as we have determined we have significant influence over their operations. We manage the day-to-day operations of 77 of the 91 joint venture properties, but have determined that our partner or partners have substantive participating rights with respect to the assets and operations of these joint venture properties. Our investments in joint ventures in Japan, South Korea, Malaysia, and Mexico comprise 12 of the remaining 14 joint venture properties. The international properties are managed locally by joint ventures in which we share oversight responsibility with our partner.

            We allocate net operating results of the Operating Partnership after preferred distributions to third parties and to us based on the partners' respective weighted average ownership interests in the Operating Partnership. Net operating results of the Operating Partnership attributed to third parties are reflected in net income attributable to noncontrolling interests. Our weighted average ownership interest in the Operating Partnership was 83.1% and 83.0% for the six months ended June 30, 2012 and 2011, respectively. As of June 30, 2012 and December 31, 2011, our ownership interest in the Operating Partnership was 83.3% and 82.8%, respectively. We adjust the noncontrolling limited partners' interests at the end of each period to reflect their interest in the Operating Partnership.

            Preferred distributions of the Operating Partnership are accrued at declaration and represent distributions on outstanding preferred units of partnership interests held by limited partners, or preferred units, and are included in net income attributable to noncontrolling interests.

6

Reclassifications

            We made certain reclassifications of prior period amounts in the consolidated financial statements to conform to the 2012 presentation. These reclassifications had no impact on previously reported net income attributable to common stockholders or earnings per share.

3.    Significant Accounting Policies

Cash and Cash Equivalents

            We consider all highly liquid investments purchased with an original maturity of 90 days or less to be cash and cash equivalents. Cash equivalents are carried at cost, which approximates fair value. Cash equivalents generally consist of commercial paper, bankers' acceptances, Eurodollars, repurchase agreements, and money market deposits or securities. Financial instruments that potentially subject us to concentrations of credit risk include our cash and cash equivalents and our trade accounts receivable. We place our cash and cash equivalents with institutions with high credit quality. However, at certain times, such cash and cash equivalents are in excess of FDIC and SIPC insurance limits.

Marketable and Non-Marketable Securities

            Marketable securities consist primarily of the investments of our captive insurance subsidiaries, available-for-sale securities, our deferred compensation plan investments, and certain investments held to fund the debt service requirements of debt previously secured by investment properties that have been sold.

            The types of securities included in the investment portfolio of our captive insurance subsidiaries typically include U.S. Treasury or other U.S. government securities as well as corporate debt securities with maturities ranging from less than 1 to 10 years. These securities are classified as available-for-sale and are valued based upon quoted market prices or other observable inputs when quoted market prices are not available. The amortized cost of debt securities, which approximates fair value, held by our captive insurance subsidiaries is adjusted for amortization of premiums and accretion of discounts to maturity. Changes in the values of these securities are recognized in accumulated other comprehensive income (loss) until the gain or loss is realized or until any unrealized loss is deemed to be other-than-temporary. We review any declines in value of these securities for other-than-temporary impairment and consider the severity and duration of any decline in value. To the extent an other-than-temporary impairment is deemed to have occurred, an impairment charge is recorded and a new cost basis is established. Subsequent changes are then recognized through other comprehensive income (loss) unless another other-than-temporary impairment is deemed to have occurred.

            Our investments in Capital Shopping Centres Group PLC, or CSCG, and Capital & Counties Properties PLC, or CAPC, are accounted for as available-for-sale securities. These investments are adjusted to their quoted market price, including a related foreign exchange component, with corresponding adjustment in other comprehensive income (loss). At June 30, 2012, we owned 35.4 million shares each of CSCG and of CAPC. At June 30, 2012, the market value of our investments in CSCG and CAPC was $178.8 million and $116.4 million, respectively, with an aggregate unrealized gain on these investments of $63.4 million. The market value of our investments in CSCG and CAPC at December 31, 2011 was $170.7 million and $100.9 million, respectively, with an aggregate unrealized gain of $39.7 million.

            Net unrealized gains recorded in other comprehensive income (loss) as of June 30, 2012 and December 31, 2011 were $65.7 million and $41.9 million, respectively, and represent the valuation and related currency adjustments for our marketable securities. As of June 30, 2012, we do not consider any of the declines in value of our marketable and non-marketable securities to be an other-than-temporary impairment, as these market value declines, if any, have existed for a short period of time, and, in the case of debt securities, we have the ability and intent to hold these securities to maturity.

            Our insurance subsidiaries are required to maintain statutory minimum capital and surplus as well as maintain a minimum liquidity ratio. Therefore, our access to these securities may be limited. Our deferred compensation plan investments are classified as trading securities and are valued based upon quoted market prices. The investments have a matching liability as the amounts are fully payable to the employees that earned the compensation. Changes in value of these securities and changes to the matching liability to employees are both recognized in earnings and, as a result, there is no impact to consolidated net income.

            As of June 30, 2012 and December 31, 2011, we also had investments of $24.9 million, which must be used to fund the debt service requirements of mortgage debt related to investment properties sold that previously

7

collateralized the debt. These investments are classified as held-to-maturity and are recorded at amortized cost as we have the ability and intent to hold these investments to maturity.

            At June 30, 2012 and December 31, 2011, we had investments of $105.1 million in non-marketable securities that we account for under the cost method. We regularly evaluate these investments for any other-than-temporary impairment in their estimated fair value and determined that no adjustment in the carrying value was required.

Loans Held for Investment

            From time to time, we may make investments in mortgage loans or mezzanine loans of third parties that own and operate commercial real estate assets located in the United States. Mortgage loans are secured, in part, by mortgages recorded against the underlying properties which are not owned by us. Mezzanine loans are secured, in part, by pledges of ownership interests of the entities that own the underlying real estate. Loans held for investment are carried at cost, net of any premiums or discounts which are accreted or amortized over the life of the related loan receivable utilizing the effective interest method. We evaluate the collectability of both interest and principal of each of these loans quarterly to determine whether the value has been impaired. A loan is deemed to be impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the existing contractual terms. When a loan is impaired, the amount of the loss accrual is calculated by comparing the carrying amount of the loan held for investment to its estimated realizable value.

            At June 30, 2012 and December 31, 2011, we had investments in mortgage and mezzanine loans with an aggregate carrying value of $86.4 million and $162.8 million, respectively. In April 2012, one of these mortgage loans with a principal balance of $76.8 million was repaid in its entirety. The remaining two loans held at June 30, 2012 mature in October 2012. One loan requires interest-only payments while the other requires payments of interest and principal based on a 30 year amortization schedule. Interest rates on these loans are fixed at 5.9% and 7.0% per annum, respectively, with a weighted average interest rate of 6.6% and approximate market rates for instruments of similar quality and duration. During the six months ended June 30, 2012 and June 30, 2011, we recorded $5.0 million and $13.9 million, respectively, in interest income earned from these loans. Payments on each of these loans were current as of June 30, 2012.

            On December 9, 2011, we paid consideration of $88.8 million to acquire a 50% equity interest in two real estate developments for which we are the construction lender. The loans primarily bear interest at 7.0% and mature in May and July 2013. At June 30, 2012 and December 31, 2011, the aggregate amount drawn on the loans was $106.9 million and $50.7 million, respectively. We consolidated these assets as of the date we acquired our equity interest and, accordingly, amounts drawn on the loans are eliminated in consolidation.

Fair Value Measurements

            Level 1 fair value inputs are quoted prices for identical items in active, liquid and visible markets such as stock exchanges. Level 2 fair value inputs are observable information for similar items in active or inactive markets, and appropriately consider counterparty creditworthiness in the valuations. Level 3 fair value inputs reflect our best estimate of inputs and assumptions market participants would use in pricing an asset or liability at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate. We have no investments for which fair value is measured on a recurring basis using Level 3 inputs.

            We hold marketable securities that totaled $454.4 million and $417.0 million at June 30, 2012 and December 31, 2011, respectively, and are considered to have Level 1 fair value inputs. In addition, we have derivative instruments which are classified as having Level 2 inputs which consist primarily of interest rate swap agreements and foreign currency forward contracts with a gross liability balance of $6.6 million and $12.2 million at June 30, 2012 and December 31, 2011, respectively, and a gross asset value of $0.1 million and $14.9 million at June 30, 2012 and December 31, 2011, respectively. We also have interest rate cap agreements with nominal values.

            Note 6 includes a discussion of the fair value of debt measured using Level 1 and Level 2 inputs. Note 5 includes a discussion of the fair values recorded in purchase accounting and impairment, using Level 2 and Level 3 inputs. Level 3 inputs to our purchase accounting and impairment analyses include our estimations of net operating results of the property, capitalization rates and discount rates.

Total noncontrolling interests reflected in equity	$	1,185,418	$	894,622

            The remaining interest in a property or portfolio of properties which are redeemable at the option of the holder or in circumstances that may be outside our control, are accounted for as temporary equity within limited partners' preferred interest in the Operating Partnership and noncontrolling redeemable interests in properties in the accompanying consolidated balance sheets. The carrying amount of the noncontrolling interest is adjusted to the redemption amount assuming the instrument is redeemable at the balance sheet date. Changes in the redemption value of the underlying noncontrolling interest are recorded within accumulated deficit. There are no noncontrolling interests redeemable at amounts in excess of fair value.

            Net income attributable to noncontrolling interests (which includes nonredeemable noncontrolling interests in consolidated properties, limited partners' interests in the Operating Partnership, redeemable noncontrolling interests in consolidated properties and preferred distributions payable by the Operating Partnership) is a component of consolidated net income. In addition, the individual components of other comprehensive income (loss) are presented in the aggregate for both controlling and noncontrolling interests, with the portion attributable to noncontrolling interests deducted from comprehensive income attributable to common stockholders.

            A rollforward of noncontrolling interests reflected in equity is as follows:

Derivative Financial Instruments

            We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. We use a variety of derivative financial instruments in the normal course of business to selectively manage or hedge a portion of the risks associated with our indebtedness and interest payments. Our objectives in using interest rate derivatives are to add stability to our interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps and caps. We require that hedging derivative instruments be highly effective in reducing the risk exposure that they are designated to hedge. As a result, there was no significant ineffectiveness from any of our derivative activities during the period. We formally designate any instrument that meets these hedging criteria, including borrowings in a foreign currency, as a hedge at the inception of the derivative contract. We have no credit-risk-related hedging or derivative activities.

            As of June 30, 2012, we had the following outstanding interest rate derivatives related to interest rate risk:

Interest Rate Derivative	Number of Instruments		Notional Amount
Interest Rate Swaps		3	$484.7 million
Interest Rate Caps		6	$444.4 million

            The carrying value of our interest rate swap agreements, at fair value, is a net liability balance of $6.2 million and $10.0 million at June 30, 2012 and December 31, 2011, respectively, and is included in other liabilities. The interest rate cap agreements were of nominal value at June 30, 2012 and December 31, 2011 and we generally do not apply hedge accounting to these arrangements.

            We are also exposed to fluctuations in foreign exchange rates on financial instruments which are denominated in foreign currencies, primarily in Japan and Europe. We use currency forward contracts and foreign currency denominated debt to manage our exposure to changes in foreign exchange rates on certain Yen and Euro-denominated receivables and net investments. Currency forward contracts involve fixing the Yen:USD or Euro:USD exchange rate for delivery of a specified amount of foreign currency on a specified date. The currency forward contracts are typically cash settled in US dollars for their fair value at or close to their settlement date. Approximately ¥4.9 billion remains as of June 30, 2012 for all forward contracts that we expect to receive through January 5, 2015. The June 30, 2012 net liability balance related to these forward contracts was $0.3 million, of which $0.4 million is included in other liabilities and $0.1 million is included in deferred costs and other assets. We have reported the changes in fair value for these forward contracts in earnings. The underlying currency adjustments on the foreign currency denominated receivables are also reported in income and generally offset the amounts in earnings for these forward contracts.

            In 2011, we entered into a Euro:USD forward contract with a €141.3 million notional value which was designated as a net investment hedge. The December 31, 2011 asset balance related to this forward was $14.9 million and is included in deferred costs and other assets. We apply hedge accounting and the change in fair value for this Euro forward contract is reflected in other comprehensive income. Changes in the value of this hedge are offset by changes in the underlying hedged Euro-denominated joint venture investment. In connection with the sale of our interest in Gallerie Commerciali Italia, S.p.A., or GCI, as further discussed in Note 5, this hedge was terminated in January 2012.

            The total gross accumulated other comprehensive loss related to our derivative activities, including our share of the other comprehensive loss from joint venture properties, approximated $102.5 million and $115.8 million as of June 30, 2012 and December 31, 2011, respectively.

4.    Per Share Data

            We determine basic earnings per share based on the weighted average number of shares of common stock outstanding during the period and we consider any participating securities for purposes of applying the two-class method. We determine diluted earnings per share based on the weighted average number of shares of common stock outstanding combined with the incremental weighted average shares that would have been outstanding assuming all

10

potentially dilutive common shares were converted into shares at the earliest date possible. The following table sets forth the computation of our basic and diluted earnings per share.

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2012		2011		2012		2011
Net Income available to Common Stockholders — Basic	$	215,445	$	205,121	$	860,855	$	384,532
Effect of dilutive securities:
Impact to General Partner's interest in Operating Partnership from all dilutive securities and options		—		51		—		29
Net Income available to Common Stockholders — Diluted	$	215,445	$	205,172	$	860,855	$	384,561
Weighted Average Shares Outstanding — Basic		303,252,359		293,367,771		299,472,884		293,224,782
Effect of stock options		1,042		34,582		1,079		127,905
Weighted Average Shares Outstanding — Diluted		303,253,401		293,402,353		299,473,963		293,352,687

            For the six months ended June 30, 2012, potentially dilutive securities include stock options, units that are exchangeable for common stock and long-term incentive performance, or LTIP, units granted under our long-term incentive performance programs that are convertible into units and exchangeable for common stock. The only securities that had a dilutive effect for the six months ended June 30, 2012 and 2011 were stock options. We accrue dividends when they are declared.

5.    Investment in Unconsolidated Entities

Real Estate Joint Ventures

            Joint ventures are common in the real estate industry. We use joint ventures to finance properties, develop new properties, and diversify our risk in a particular property or portfolio of properties. We held joint venture ownership interests in 79 properties in the United States as of June 30, 2012 and 87 properties as of December 31, 2011. At June 30, 2012, we also held interests in eight joint venture properties in Japan, two joint venture properties in South Korea, one joint venture property in Mexico, and one joint venture property in Malaysia. We account for these joint venture properties using the equity method of accounting. As discussed below, on January 9, 2012, we sold our interest in GCI which owns 45 properties located in Italy. Additionally, on March 14, 2012, we purchased a 28.7% equity stake in Klépierre. On May 21, 2012 Klépierre paid a dividend, which we elected to receive in additional shares, resulting in an increase in our ownership to approximately 28.9%.

            Certain of our joint venture properties are subject to various rights of first refusal, buy-sell provisions, put and call rights, or other sale or marketing rights for partners which are customary in real estate joint venture agreements and our industry. We and our partners in these joint ventures may initiate these provisions (subject to any applicable lock up or similar restrictions), which may result in either the sale of our interest or the use of available cash or borrowings, or the use of limited partnership interests in the Operating Partnership, to acquire the joint venture interest from our partner.

Unconsolidated Property Transactions

            On January 6, 2012, SPG-FCM Ventures, LLC, or SPG-FCM, which holds our investment in The Mills Limited Partnership, or TMLP, distributed its interest in Del Amo Fashion Center to SPG-FCM's joint venture partners. We purchased our venture partner's 25% interest for $50.0 million, which increased our ownership in the property to 50%. As a part of the transaction, we and our venture partner each contributed $50.0 million to SPG-FCM which was used to pay down TMLP's senior loan and the loan we made to SPG-FCM, as discussed below.

            On March 22, 2012, we acquired, through an acquisition of substantially all of the assets of TMLP, additional interests in 26 properties, or the Mills transaction, from our joint venture partner. The transaction resulted in 16 of the

11

properties remaining unconsolidated, the consolidation of nine previously unconsolidated properties and the purchase of the remaining noncontrolling interest in a previously consolidated property. The transaction was valued at $1.5 billion, which included repayment of the remaining $562.1 million balance on TMLP's senior loan facility, and retirement of $100.0 million of TMLP's trust preferred securities. In connection with the transaction, our $558.4 million loan to SPG-FCM was extinguished on a non-cash basis. We consolidated $2.6 billion in additional property-level mortgage debt in connection with this transaction. This property-level mortgage debt was previously presented as debt of our unconsolidated entities. We and our joint venture partner had equal ownership in these properties prior to the transaction.

            The consolidation of the previously unconsolidated properties resulted in a remeasurement of our previously held interest in each of these properties to fair value and recognition of a corresponding non-cash gain of $488.7 million. In addition, we recorded an other-than-temporary impairment charge of $22.4 million for the excess of carrying value of our remaining investment in SPG-FCM over its estimated fair value. The gain on the transaction and impairment charge are included in gain (loss) upon acquisition of controlling interests, sale or disposal of assets and interests in unconsolidated entities, and impairment charge on investment in unconsolidated entities, net in the accompanying consolidated statements of operations and comprehensive income. The assets and liabilities of the newly consolidated properties acquired in the Mills transaction have been reflected at their estimated fair value at the acquisition date, the majority of which, approximately $4.3 billion, was allocated to the investment property. This purchase price allocation is preliminary and is subject to revision within the measurement period, not to exceed one year from the date of acquisition.

            On December 31, 2011, as discussed in Note 9, we and our joint venture partner dissolved a venture in which we had a 50% interest and distributed a portfolio of properties previously held within the venture to us and our joint venture partner.

Loan to SPG-FCM

            As discussed above, our loan to SPG-FCM was extinguished in the Mills transaction. During the six month periods ended June 30, 2012 and 2011, we recorded $2.0 million and $4.9 million in interest income (net of inter-entity eliminations), related to this loan, respectively. The loan bore interest at a rate of LIBOR plus 275 basis points.

European Investments

            At June 30, 2012, we owned 57,634,148 shares, or approximately 28.9%, of Klépierre, which had a quoted market price of $32.80 per share. At the date of purchase on March 14, 2012, our excess investment in Klépierre was approximately $1.2 billion which we have allocated, on a preliminary basis, to the underlying investment property, other assets and liabilities based on estimated fair value. Our share of the results of Klépierre, net of the amortization of our excess investment, during our ownership period was nominal.

            Based on applicable Euro:USD exchange rates and after our conversion of Klépierre's results to GAAP, Klépierre's total revenues, operating income and consolidated net income were approximately $407.7 million, $154.4 million and $93.1 million, respectively, for the period of our ownership in 2012.

            At December 31, 2011, we had a 49% ownership interest in GCI. On January 9, 2012, we sold our entire ownership interest in GCI to our venture partner, Auchan S.A. The aggregate cash we received related to the sale of our interest GCI was $375.8 million and we recognized a gain on the sale of $28.8 million. Our investment carrying value included $39.5 million of accumulated losses related to currency translation and net investment hedge accumulated balances, which had been recorded in accumulated other comprehensive income (loss).

Asian Joint Ventures

            We conduct our international Premium Outlet operations in Japan through a joint venture with Mitsubishi Estate Co., Ltd. We have a 40% ownership interest in this joint venture. The carrying amount of our investment in this joint venture was $335.9 million and $349.5 million as of June 30, 2012 and December 31, 2011, respectively, including all related components of accumulated other comprehensive income (loss). We conduct our international Premium Outlet operations in South Korea through a joint venture with Shinsegae International Co. We have a 50% ownership interest in this joint venture. The carrying amount of our investment in this joint venture was $58.3 million and $43.8 million as of June 30, 2012 and December 31, 2011, respectively, including all related components of accumulated other comprehensive income (loss).

Summary Financial Information

            A summary of our investments in joint ventures and share of income from our joint ventures, excluding Klépierre, follows. The statements of operations include amounts related to our investment in GCI, which was sold on January 9, 2012. In addition, we acquired additional controlling interests in The Plaza at King of Prussia and The Court at King of Prussia, or collectively, King of Prussia, on August 25, 2011 and nine properties in the Mills transaction on March 22, 2012. These previously unconsolidated properties became consolidated properties as of their respective acquisition dates. Additionally, on December 31, 2011, we and our joint venture partner dissolved a venture in which we had a 50% interest and distributed a portfolio of properties previously held within the venture to us and our joint venture partner. The results of operations of the properties for all of these transactions are classified as loss from operations of discontinued joint venture interests in the accompanying joint venture statements of operations. Balance sheet information for the joint ventures is as follows:

6.    Debt

Unsecured Debt

            At June 30, 2012, our unsecured debt consisted of $12.3 billion of senior unsecured notes of the Operating Partnership, $1.8 billion outstanding under our $4.0 billion unsecured revolving credit facility, or Credit Facility, and $278.3 million outstanding under our $2.0 billion supplemental unsecured revolving credit facility, or Supplemental Facility. The June 30, 2012 balance on the Credit Facility included $1.1 billion (U.S. dollar equivalent) of Euro-denominated borrowings and the entire balance on the Supplemental Facility on such date consisted of Yen-denominated borrowings, both of which are designated as net investment hedges of our international investments.

            On June 30, 2012, we had an aggregate available borrowing capacity of $3.9 billion under the two credit facilities. The maximum outstanding balance of the credit facilities during the six months ended June 30, 2012 was $3.1 billion and the weighted average outstanding balance was $1.6 billion. Letters of credit of $38.9 million were outstanding under the Credit Facility as of June 30, 2012.

14

            The Credit Facility's initial borrowing capacity of $4.0 billion can be increased at our option to $5.0 billion during its term. The Credit Facility will initially mature on October 30, 2015 and can be extended for an additional year at our sole option. The base interest rate on the Credit Facility is LIBOR plus 100 basis points with an additional facility fee of 15 basis points. In addition, the Credit Facility provides for a money market competitive bid option program that allows us to hold auctions to achieve lower pricing for short-term borrowings. The Credit Facility also includes a $2.0 billion multi-currency tranche.

            On June 1, 2012, we entered into a Supplemental Facility with an initial borrowing capacity of $2.0 billion which can be increased at our option to $2.5 billion during its term. The Supplemental Facility will initially mature on June 30, 2016 and can be extended for an additional year at our sole option. The base interest rate on the Supplemental Facility is LIBOR plus 100 basis points with an additional facility fee of 15 basis points. Like the Credit Facility, the Supplemental Facility provides for a money market competitive bid option program and allows for multi-currency borrowings. During the second quarter of 2012, we rolled $285.0 million (USD equivalent) of yen-denominated borrowings under the Credit Facility to the Supplemental Facility.

            On March 13, 2012, the Operating Partnership issued $600.0 million of senior unsecured notes at a fixed interest rate of 2.15% with a maturity date of September 2017, $600.0 million of senior unsecured notes at a fixed interest rate of 3.375% with a maturity date of March 2022, and $550.0 million of senior unsecured notes at a fixed interest rate of 4.75% with a maturity date of March 2042. Proceeds from the unsecured notes offerings were used to fund a portion of the cost of the acquisition of our equity stake in Klépierre and the Mills transaction.

            During the six months ended June 30, 2012, we redeemed at par $124.9 million of senior unsecured notes with fixed rates ranging from 5.75% to 6.88%.

            On November 1, 2011, we entered into a $900.0 million unsecured term loan. We drew $160.0 million on the term loan in the first quarter of 2012. In the second quarter of 2012, we repaid the outstanding balance in full and terminated the term loan.

Secured Debt

            Total secured indebtedness was $8.0 billion and $6.8 billion at June 30, 2012 and December 31, 2011, respectively. During the six months ended June 30, 2012, we repaid $427.8 million in mortgage loans with a weighted average interest rate of 3.17%, unencumbering seven properties, and repaid the outstanding balance of a $735.0 million secured term loan in full.

            As a result of the acquisition of additional interests in properties in the Mills transaction in March 2012, as further discussed in Note 5, we consolidated nine properties encumbered by property-level mortgage debt totaling $2.6 billion. This property-level mortgage debt was previously presented as debt of our unconsolidated entities. We and our joint venture partner had equal ownership in these properties prior to the transaction.

Covenants

            Our unsecured debt agreements contain financial covenants and other non-financial covenants. If we were to fail to comply with these covenants, after the expiration of the applicable cure periods, the debt maturity could be accelerated or other remedies could be sought by the lender including adjustments to the applicable interest rate. As of June 30, 2012, we are in compliance with all covenants of our unsecured debt.

            At June 30, 2012, we or our subsidiaries are the borrowers under 90 non-recourse mortgage notes secured by mortgages on 90 properties, including 8 separate pools of cross-defaulted and cross-collateralized mortgages encumbering a total of 38 properties. Under these cross-default provisions, a default under any mortgage included in the cross-defaulted pool may constitute a default under all mortgages within that pool and may lead to acceleration of the indebtedness due on each property within the pool. Certain of our secured debt contain financial and other non-financial covenants which are specific to the properties which serve as collateral for that debt. If the borrower fails to comply with these covenants, the lender could accelerate the debt and enforce its right against their collateral. At June 30, 2012, the applicable borrowers under these non-recourse mortgage notes were in compliance with all covenants where non-compliance individually, or giving effect to applicable cross-default provisions in the aggregate, could have a material adverse effect on our financial condition, results of operations or cash flows.

15

Fair Value of Debt

            The carrying value of our variable-rate mortgages and other loans approximates their fair values. We estimate the fair values of consolidated fixed-rate mortgages using cash flows discounted at current borrowing rates and other indebtedness using cash flows discounted at current market rates. We estimate the fair values of consolidated fixed-rate unsecured notes using quoted market prices, or, if no quoted market prices are available, we use quoted market prices for securities with similar terms and maturities. The book value of our consolidated fixed-rate mortgages and other indebtedness was $19.8 billion and $15.9 billion as of June 30, 2012 and December 31, 2011, respectively. The fair values of these financial instruments and the related discount rate assumptions as of June 30, 2012 and December 31, 2011 are summarized as follows:

	June 30, 2012		December 31, 2011
Fair value of fixed-rate mortgages and other indebtedness	$	22,065	$17,905

            During the first six months of 2012, we issued 221,109 shares of common stock to 16 limited partners in exchange for an equal number of units.

            On March 14, 2012, we issued 9,137,500 shares of common stock in a public offering at a price of $137.00 per share. Proceeds of $1.2 billion from the offering, net of issue costs, were used to fund a portion of the acquisition cost of our equity stake in Klépierre and the Mills transaction.

            On July 20, 2012, the Operating Partnership redeemed 2,000,000 units from a limited partner for $124.00 per unit in cash.

Stock Based Compensation

            The Compensation Committee of our Board of Directors, or the Compensation Committee, awarded 12,034 shares of restricted stock to employees on March 5, 2012 and March 14, 2012 under The Simon Property Group, L.P. 1998 Stock Incentive Plan, or the Plan, at a fair market value of $138.41 per share and $141.12 per share, respectively. On June 1, 2012, our non-employee Directors were awarded 4,094 shares of restricted stock under the Plan at a fair market value of $143.51 per share as a result of their re-election to our Board. The fair market value of the restricted stock awarded on March 5, 2012 and March 14, 2012 is being recognized as expense over the three-year vesting service period. The fair market value of the restricted stock awarded on June 1, 2012 to our non-employee Directors is being recognized as expense over the one-year vesting service period.

            On March 16, 2010, the Compensation Committee of our Board approved three long-term incentive performance programs, or the 2010 LTIP programs, for certain senior executive officers. Awards under the 2010 LTIP programs take the form of LTIP units, a form of limited partnership interest issued by the Operating Partnership. During the performance period, participants are entitled to receive on the LTIP units awarded to them distributions equal to 10% of the regular quarterly distributions paid on a unit of the Operating Partnership. As a result, we account for these LTIP units as participating securities under the two-class method of computing earnings per share. Awarded LTIP units will be considered earned, in whole or in part, depending upon the extent to which the applicable total shareholder return, or TSR, benchmarks, as defined, are achieved during the performance period and, once earned, will become the equivalent of units after a two year service-based vesting period, beginning after the end of the performance period. Awarded LTIP units not earned are forfeited.

            The 2010 LTIP programs have one, two and three year performance periods, which end on December 31, 2010, 2011 and 2012, respectively. During July 2011, the Compensation Committee approved a three-year long-term incentive performance program, or the 2011-2013 LTIP program, and awarded LTIP units to certain senior executive officers. The 2011-2013 LTIP program has a three year performance period ending on December 31, 2013. During March 2012, the Compensation Committee approved a three-year long-term incentive performance program, or the 2012-2014 LTIP program, and awarded LTIP units to certain senior executive officers. The 2012-2014 LTIP program has a three year performance period ending December 31, 2014. After the end of each performance period, any earned LTIP units will then be subject to service-based vesting over a period of two years. One-half of the earned LTIP

16

units will vest on January 1 of each of the second and third years following the end of the applicable performance period, subject to the participant maintaining employment with us through those dates.

            The 2010 LTIP program awards have an aggregate grant date fair value, adjusted for estimated forfeitures, of $7.2 million for the one-year program, $14.8 million for the two-year program and $23.0 million for the three-year program. The 2011-2013 LTIP program awards have an aggregate grant date fair value of $35.0 million, adjusted for estimated forfeitures. The 2012-2014 LTIP program awards have an aggregate grant date fair value of $35.0 million, adjusted for estimated forfeitures. Grant date fair values were estimated based upon the results of a Monte Carlo model, and the resulting expense will be recorded regardless of whether the TSR benchmarks are achieved. The grant date fair values are being amortized into expense over the period from the grant date to the date at which the awards, if any, become vested. In 2011, the Compensation Committee determined that 133,673 LTIP units were earned under the one-year 2010 LTIP program and, pursuant to the award agreements, will vest in two equal installments in 2012 and 2013. In the first quarter of 2012, the Compensation Committee determined that 337,006 LTIP units were earned under the two-year 2010 LTIP program and, pursuant to the award agreements, will vest in two equal installments in 2013 and 2014.

            On July 6, 2011, in connection with the execution of an employment agreement, the Compensation Committee granted David Simon, our Chairman and CEO, a retention award in the form of 1,000,000 LTIP units. The award vests in one-third increments on July 5^th of 2017, 2018 and 2019, subject to continued employment. The grant date fair value of the retention award was $120.3 million which is being recognized as expense over the eight-year term of his employment agreement on a straight-line basis.

8.    Commitments and Contingencies

Litigation

            We are involved from time-to-time in various legal proceedings that arise in the ordinary course of our business, including, but not limited to commercial disputes, environmental matters, and litigation in connection with transactions including acquisitions and divestitures. We believe that such litigation, claims and administrative proceedings will not have a material adverse impact on our financial position or our results of operations. We record a liability when a loss is known or considered probable and the amount can be reasonably estimated.

            In May 2010, Opry Mills sustained significant flood damage. Insurance proceeds of $50 million have been funded by the insurers and remediation work has been completed. The property was re-opened March 29, 2012. The excess insurance carriers (those providing coverage above $50 million) have denied the claim under the policy for additional proceeds (of up to $150 million) to pay further amounts for restoration costs and business interruption losses. We and our lenders are continuing our efforts through pending litigation to recover our losses under the excess insurance policies for Opry Mills and we believe recovery is probable, but no assurances can be made that our efforts to recover these funds will be successful.

Guarantees of Indebtedness

            Joint venture debt is the liability of the joint venture and is typically secured by the joint venture property, which is non-recourse to us. As of June 30, 2012 and December 31, 2011, the Operating Partnership guaranteed joint venture related mortgage or other indebtedness of $101.6 million and $30.2 million, respectively. Mortgages guaranteed by us are secured by the property of the joint venture and that property could be sold in order to satisfy the outstanding obligation.

Concentration of Credit Risk

            Our malls, Premium Outlets, The Mills, and community/lifestyle centers rely heavily upon anchor retailers to attract customers; however anchor tenants do not contribute materially to our financial results as many anchor retailers own their spaces. All material operations are within the United States and no customer or tenant accounts for 5% or more of our consolidated revenues.

9.    Real Estate Acquisitions and Dispositions

            On June 4, 2012, we acquired a 50% interest in a 465,000 square foot outlet center located in Destin, Florida for $70.5 million.

            On May 3, 2012, we sold our investment in two residential apartment buildings located at The Domain in Austin, TX. Our share of the gain from the sale is $12.1 million, which is included in other income in the consolidated statements of operations and comprehensive income.

            On March 22, 2012, as part of the Mills transaction discussed in Note 5, we acquired additional interests in 26 of our joint venture properties in a transaction valued at approximately $1.5 billion.

            On March 14, 2012, as discussed in Note 5, we acquired a 28.7% equity stake in Klépierre for approximately $2.0 billion, including the capitalization of acquisition costs.

            On January 9, 2012, as discussed in Note 5, we sold our entire ownership interest in GCI to our venture partner, Auchan S.A.

            On January 6, 2012, as discussed in Note 5, we purchased an additional 25% interest in Del Amo Fashion Center.

            During the first quarter of 2012, we sold one of our other retail properties with a carrying value of $115.0 million for nominal consideration and the assumption of the related mortgage debt of $115.0 million by the acquirer.

            On December 31, 2011, we and our joint venture partner dissolved a venture in which we had a 50% interest and distributed a portfolio of properties previously held within the venture to us and our joint venture partner. As a result, we have a 100% interest in and now consolidate the six properties we received in the distribution. The distribution resulted in a remeasurement of the distributed assets to estimated fair value and a corresponding non-cash gain of $168.3 million in the fourth quarter of 2011 representing the estimated fair value of the net assets received in excess of the carrying value of our interest in the joint venture portfolio. The asset and liability fair value allocation

18

were recorded based on preliminary portfolio fair value estimates at the date of distribution and will be finalized during 2012.

            On August 25, 2011, we acquired additional controlling interests of approximately 83.75% in King of Prussia thereby increasing our ownership interest to 96.1%. The property is subject to a $160.1 million mortgage. The consolidation of this previously unconsolidated property resulted in a remeasurement of our previously held interest to fair value and a corresponding non-cash gain of $82.9 million in the third quarter of 2011.

            During the six months ended June 30, 2011, we disposed of our interests in two retail properties for a net gain of $7.2 million. Additionally on June 28, 2011, we sold one of our other retail properties for $134.0 million, resulting in a net gain of $6.6 million. These gains are included gain (loss) upon acquisition of controlling interests, sale or disposal of assets and interests in unconsolidated entities, and impairment charge on investment in unconsolidated entities, net in the accompanying consolidated statements of operations and comprehensive income.

            We expense acquisition and potential acquisition costs related to business combinations and disposition related costs as they are incurred. We incurred a minimal amount of transaction expenses during the six months ended June 30, 2012 and 2011.

Item 2.    Management's Discussion and Analysis of Financial Condition and Results of Operations

            You should read the following discussion in conjunction with the financial statements and notes thereto included in this report.

Overview

            Simon Property Group, Inc., or Simon Property, is a Delaware corporation that operates as a self-administered and self-managed real estate investment trust, or REIT, under the Internal Revenue Code. To qualify as a REIT, among other things, a company must distribute at least 90% of its taxable income to its stockholders annually. Taxes are paid by stockholders on dividends received and any capital gains distributed. Most states also follow this federal treatment and do not require REITs to pay state income tax. Simon Property Group, L.P., or the Operating Partnership, is a majority-owned partnership subsidiary that owns all of our real estate properties and other assets. In this discussion, the terms "we", "us" and "our" refer to Simon Property, the Operating Partnership, and its subsidiaries.

            We own, develop and manage retail real estate properties, which consist primarily of malls, Premium Outlets®, The Mills®, and community/lifestyle centers. As of June 30, 2012, we owned or held an interest in 325 income-producing properties in the United States, which consisted of 161 malls, 60 Premium Outlets, 70 community/lifestyle centers, 13 properties in The Mills portfolio, and 21 other shopping centers or outlet centers in 41 states and Puerto Rico. Internationally, as of June 30, 2012, we had ownership interests in eight Premium Outlets in Japan, two Premium Outlets in South Korea, one Premium Outlet in Mexico, and one Premium Outlet in Malaysia. Additionally, as of June 30, 2012, we owned a 28.9% equity stake in Klépierre SA, or Klépierre, a publicly traded, Paris-based real estate company, which owns, or has an interest in, more than 260 shopping centers located in 13 countries in Europe.

            We generate the majority of our revenues from leases with retail tenants including:

•

base minimum rents,

•

overage and percentage rents based on tenants' sales volume, and

•

recoveries of substantially all of our recoverable expenditures, which consist of property operating, real estate taxes, repair and maintenance, and advertising and promotional expenditures.

            Revenues of our management company, after intercompany eliminations, consist primarily of management fees that are typically based upon the revenues of the property being managed.

            We invest in real estate properties to maximize total financial return which includes both operating cash flows and capital appreciation. We seek growth in earnings, funds from operations, or FFO, and cash flows by enhancing the profitability and operation of our properties and investments. We seek to accomplish this growth through the following:

•

attracting and retaining high quality tenants and utilizing economies of scale to reduce operating expenses,

•

expanding and re-tenanting existing highly productive locations at competitive rental rates,

•

selectively acquiring or increasing our interests in high quality real estate assets or portfolios of assets,

•

generating consumer traffic in our retail properties through marketing initiatives and strategic corporate alliances, and

•

selling selective non-core assets.

            We also grow by generating supplemental revenues from the following activities:

•

establishing our malls as leading market resource providers for retailers and other businesses and consumer-focused corporate alliances, including: payment systems (such as handling fees relating to the sales of bank-issued prepaid cards), national marketing alliances, static and digital media initiatives, business development, sponsorship, and events,

•

offering property operating services to our tenants and others, including waste handling and facility services, and the provision of energy services,

20

•

selling or leasing land adjacent to our shopping center properties, commonly referred to as "outlots" or "outparcels," and

•

generating interest income on cash deposits and investments in loans, including those made to related entities.

            We focus on high quality real estate across the retail real estate spectrum. We expand or renovate properties to enhance profitability and market share of existing assets when we believe the investment of our capital meets our risk-reward criteria. We selectively develop new properties in metropolitan areas that exhibit strong population and economic growth.

            We routinely review and evaluate acquisition opportunities based on their ability to complement our portfolio. Our international strategy includes partnering with established real estate companies and financing international investments with local currency to minimize foreign exchange risk.

            To support our growth, we employ a three-fold capital strategy:

•

provide the capital necessary to fund growth,

•

maintain sufficient flexibility to access capital in many forms, both public and private, and

•

manage our overall financial structure in a fashion that preserves our investment grade credit ratings.

            We consider FFO, net operating income, or NOI, and comparable property NOI (NOI for properties owned and operating in both periods under comparison) to be key measures of operating performance that are not specifically defined by accounting principles generally accepted in the United States, or GAAP. We use these measures to evaluate the performance of our portfolio and provide a basis for comparison with other real estate companies. Reconciliations of these measures to the most comparable GAAP measure are included below in this discussion.

Results Overview

            Diluted earnings per common share increased $1.56 during the first six months of 2012 to $2.87 from $1.31 for the same period last year. The increase in diluted earnings per share was primarily attributable to:

•

improved operating performance and core business fundamentals in 2012 and the impact of our acquisition and expansion activity, and

•

a 2012 gain due to the acquisition of a controlling interest, sale or disposal of assets and interests in unconsolidated entities, and impairment charge on investment in unconsolidated entities of $494.8 million, or $1.37 per diluted share, primarily driven by a gain of $488.7 million resulting from the remeasurement of our previously held interest to fair value for those properties where we now have a controlling interest,

•

partially offset by increased interest expense as discussed below.

            Core business fundamentals during the first six months of 2012 improved from the economic environment that existed during the first six months of 2011 primarily driven by higher tenant sales, especially within the luxury segment. Our share of portfolio NOI grew by 16.9% and 12.8% for the three and six month periods in 2012 over the prior year periods, respectively. Comparable property NOI also grew 5.1% for the current period and 5.6% for the year to date for our U.S. portfolio of malls and Premium Outlets. Total sales per square foot, or psf, increased 9.9% from June 30, 2011 to $554 psf at June 30, 2012 for our portfolio of U.S. malls and Premium Outlets. Average base minimum rent increased 3.7% to $39.99 psf as of June 30, 2012, from $38.57 psf as of June 30, 2011. Releasing spreads remained positive in the U.S. malls and Premium Outlets as we were able to lease available square feet at higher rents than the expiring rental rates on the same space, resulting in a releasing spread (based on total tenant payments — base minimum rent plus common area maintenance) of $4.77 psf ($52.29 openings compared to $47.52 closings) as of June 30, 2012, representing a 10.0% increase over expiring payments as of June 30, 2012. Ending occupancy for the U.S. malls and Premium Outlets was 94.2% as of June 30, 2012, as compared to 93.6% as of June 30, 2011, an increase of 60 basis points.

            Our effective overall borrowing rate at June 30, 2012 decreased 30 basis points to 5.22% as compared to 5.52% at June 30, 2011. This decrease was primarily due to a decrease in the effective overall borrowing rate on fixed rate debt of 44 basis points (5.58% at June 30, 2012 as compared to 6.02% at June 30, 2011) and a decrease in the effective overall borrowing rate on variable rate debt of 10 basis points (1.74% at June 30, 2012 as compared to 1.84% at

21

June 30, 2011). At June 30, 2012, the weighted average years to maturity of our consolidated indebtedness was 6.1 years as compared to 5.7 years at December 31, 2011. Our financing activities for the six months ended June 30, 2012, included the repayment of $427.8 million in mortgage loans with a weighted average interest rate of 3.17% unencumbering seven properties, the redemption of $124.9 million of senior unsecured notes with fixed rates ranging from 5.75% to 6.88% and the repayment of a $735.0 million secured term loan. In addition, during the 2012 period, we issued $600.0 million of senior unsecured notes at a fixed interest rate of 2.15% with a maturity date of September 2017, $600.0 million of senior unsecured notes at a fixed interest rate of 3.375% with a maturity date of March 2022 and $550.0 million of senior unsecured notes at a fixed interest rate of 4.75% with a maturity date of March 2042. At June 30, 2012, we also had net $1.1 billion (U.S. dollar equivalent) of Euro-denominated borrowings on our $4.0 billion unsecured revolving credit facility, or Credit Facility.

United States Portfolio Data

            The portfolio data discussed in this overview includes the following key operating statistics: ending occupancy, average base minimum rent per square foot, and total sales per square foot for our domestic assets. We include acquired properties in this data beginning in the year of acquisition and remove properties sold in the year disposed. For comparative purposes, we separate the information related to community/lifestyle centers and The Mills from our other U.S. operations. We also do not include any properties located outside of the United States.

            The following table sets forth these key operating statistics for:

•

properties that are consolidated in our consolidated financial statements,

•

properties we account for under the equity method of accounting as joint ventures, and

•

the foregoing two categories of properties on a total portfolio basis.

            Ending Occupancy Levels and Average Base Minimum Rent per Square Foot.    Ending occupancy is the percentage of gross leasable area, or GLA, which is leased as of the last day of the reporting period. We include all company owned space except for mall anchors and mall majors in the calculation. Base minimum rent per square foot is the average base minimum rent charge in effect for the reporting period for all tenants that would qualify to be included in ending occupancy.

            Total Sales per Square Foot.    Total sales include total reported retail tenant sales on a trailing 12-month basis at owned GLA (for mall and freestanding stores with less than 10,000 square feet) in the malls and all reporting tenants at the Premium Outlets and The Mills. Retail sales at owned GLA affect revenue and profitability levels because sales determine the amount of minimum rent that can be charged, the percentage rent realized, and the recoverable expenses (common area maintenance, real estate taxes, etc.) that tenants can afford to pay.

Current Leasing Activities

            During the six months ended June 30, 2012, we signed 572 new leases and 1,075 renewal leases (excluding new development, redevelopment, expansion, downsizing and relocation) across our U.S. malls and Premium Outlets portfolio, comprising nearly 5.6 million square feet of which 4.2 million square feet related to consolidated properties. During the comparable period in 2011, we signed 674 new leases and 1,093 renewal leases, comprising approximately 6.0 million square feet of which 4.5 million square feet related to consolidated properties. The average initial base minimum rent for these new leases was $37.78 psf in 2012 and $36.78 psf in 2011 with an average tenant allowance on new leases of $35.51 psf and $28.17 psf, respectively.

International Property Data

            The following are selected key operating statistics for our Premium Outlets in Japan. The information used to prepare these statistics has been supplied by the managing venture partner.

Results of Operations

            In addition to the activity discussed above in the "Results Overview" section, the following acquisitions, openings, and dispositions of consolidated properties affected our consolidated results from continuing operations in the comparative periods:

•

On March 29, 2012, Opry Mills re-opened after completion of the restoration of the property following the significant flood damage which occurred in May 2010.

•

On March 22, 2012, we acquired additional interests in 26 joint venture properties previously owned by the Mills Limited Partnership, or TMLP, from our joint venture partner. Of these 26 properties acquired in the transaction, or the Mills transaction, nine became consolidated properties at the acquisition date.

During 2011, we disposed of four of our other retail properties and one of our malls.

•

On December 31, 2011, as discussed in Note 9 of the condensed notes to consolidated financial statements, a 50% joint venture distributed a portfolio of properties to us and our joint venture partner. We now consolidate those properties we received in the distribution.

23

•

On August 25, 2011, we acquired additional interests in The Plaza at King of Prussia and The Court at King of Prussia, or, collectively, King of Prussia, a 2.4 million square foot mall in the Philadelphia market, which had previously been accounted for under the equity method. We now have a controlling interest in this property and its results are consolidated as of the acquisition date.

•

On July 19, 2011, we acquired a 100% ownership interest in ABQ Uptown, a 222,000 square foot lifestyle center located in Albuquerque, New Mexico.

            In addition to the activities discussed above and in "Results Overview," the following acquisitions, dispositions and openings of joint venture properties affected our income from unconsolidated entities in the comparative periods:

•

On June 4, 2012, we acquired a 50% interest in a 465,000 square foot outlet center located in Destin, Florida.

•

As discussed above, on March 22, 2012, we acquired additional interests in 26 joint venture properties in the Mills transaction. Of these 26 assets, 16 remain unconsolidated.

During the third quarter of 2011, we contributed a wholly-owned property to a joint venture which holds our interests in nine unconsolidated properties. The transaction effectively exchanged a portion of our interest in this previously wholly-owned property for increased ownership interests in the nine unconsolidated properties.

•

On March 17, 2011, we and our partner, Shinsegae International Co., opened Paju Premium Outlets, a 328,000 square foot outlet center in Paju, South Korea.

            For the purposes of the following comparison between the three and six months ended June 30, 2012 and 2011, the above transactions are referred to as the property transactions. In the following discussions of our results of operations, "comparable" refers to properties we owned and operated in both of the periods under comparison.

Three Months Ended June 30, 2012 vs. Three Months Ended June 30, 2011

            Minimum rents increased $96.6 million during the 2012 period, of which the property transactions accounted for $79.4 million of the increase. Comparable rents increased $17.2 million, or 2.7%. The increase in comparable rents was primarily attributable to a $17.1 million increase in base minimum rents. Overage rents increased $9.4 million, or 43.0%, primarily as a result of an increase in tenant sales for the period compared to the prior period at the comparable properties of $6.1 million.

            Tenant reimbursements increased $44.8 million, due to a $38.2 million increase attributable to the property transactions and a $6.6 million, or 2.4%, increase in the comparable properties primarily due to annual increases related to common area maintenance reimbursements.

            Total other income decreased $0.8 million, principally as a result of a decrease in interest income of $13.5 million primarily related to the repayment of loans held for investment and timing of the semi-annual dividends from our investments in CSCG and CAPC, partially offset by a $12.1 million gain on the sale of our investments in two multi-family residential facilities and a $0.6 million increase in net other activity.

            Property operating expense increased $7.0 million primarily related to a $13.9 million increase attributable to the property transactions partially offset by a $6.9 million decrease in comparable property activity due primarily to our continued cost savings efforts.

24

            Depreciation and amortization expense increased $50.6 million primarily due to the additional depreciable assets related to the property transactions.

            Real estate tax expense increased $13.4 million primarily related to the property transactions.

            Home and regional office expense increased $3.7 million primarily due to normal merit increase and increased long-term performance based incentive compensation costs.

            General and administrative expense increased $5.8 million primarily as a result of increased long-term performance based incentive compensation costs including amortization of the CEO retention award.

            Other expense increased $4.9 million primarily related to a $5.1 million increase attributable to the property transactions, offset partially by a net $0.2 million decrease in comparable property activity.

            Interest expense increased $44.0 million primarily related to a $33.0 million increase related to the property transactions. The remainder of the increase resulted from borrowings on the Euro tranche of the Credit Facility and the issuance of unsecured notes in the fourth quarter of 2011 and the first quarter of 2012 which were partially offset by decreased interest expense related to our payoff of a $735.0 million secured term loan, and our payoff of $542.5 million of unsecured notes in 2011 and $124.8 million of unsecured notes in 2012.

            Income from unconsolidated properties increased $15.3 million as result of the property transactions, primarily our increased ownership in the joint venture properties acquired as part of the Mills transaction, and favorable results of operations from the portfolio of joint venture properties.

            During the quarter ended June 30, 2011, we disposed of our interest in an unconsolidated mall and sold one of our other retail properties for an aggregate gain of $14.3 million.

Six Months Ended June 30, 2012 vs. Six Months Ended June 30, 2011

            Minimum rents increased $154.4 million during the 2012 period, of which the property transactions accounted for $116.7 million of the increase. Comparable rents increased $37.7 million, or 3.0%, primarily attributable to a $36.8 million increase in base minimum rents. Overage rents increased $20.0 million, or 51.1%, primarily as a result of an increase in tenant sales for the period compared to the prior period at the comparable properties of $15.1 million.

            Tenant reimbursements increased $69.8 million, due to a $58.2 million increase attributable to the property transactions and a $11.6 million, or 2.1%, increase in the comparable properties primarily due to annual increases related to common area maintenance and real estate tax reimbursements.

            Total other income increased $3.2 million, principally as a result of a $12.1 million increase from a gain on the sale of our investments in two multi-family residential facilities, a $6.9 million increase in financing and other fee revenue earned from joint ventures net of eliminations, partially offset by a decrease in interest income of $17.4 million primarily related to a reduction in the aggregate amount of loans held for investment and timing of the semi-annual dividends from our investments in CSCG and CAPC.

            Property operating expense increased $12.2 million primarily related to a $20.2 million increase attributable to the property transactions partially offset by a $8.0 million decrease in comparable property activity due primarily to a mild winter and our continued cost savings efforts.

            Depreciation and amortization expense increased $69.4 million primarily due to the additional depreciable assets related to the property transactions.

            Real estate tax expense increased $18.8 million primarily related to the property transactions.

            In the first six months of 2012, we recorded a provision for credit losses of $6.5 million as compared to a provision of $1.7 million in the prior year period. The lower provision in 2011 reflected strong collections and recoveries of receivables for which we had previously established reserves due to the uncertainty of ultimate payment.

            Home and regional office expense increased $7.5 million primarily due to normal merit increase and increased long-term performance based incentive compensation costs.

            General and administrative expense increased $12.0 million primarily as a result of increased long-term performance based incentive compensation costs including amortization of the CEO retention award.

25

            Other expenses increased $3.6 million primarily related to a $5.4 million increase attributable to the property transactions, offset partially by a decrease in legal fees and net other activity.

            Interest expense increased $54.0 million primarily related to an increase of $46.6 million related to the property transactions. The remainder of the increase resulted from borrowings on the Euro tranche of the Credit Facility and the issuance of unsecured notes in the fourth quarter of 2011 and the first quarter of 2012 which were partially offset by decreased interest expense related to the repayment or refinancing of mortgages at nine properties, payoff of a $735.0 million secured term loan, and our payoff of $542.5 million of unsecured notes in 2011 and $124.8 million of unsecured notes in 2012.

            Income from unconsolidated properties increased $27.0 million as result of the property transactions, primarily our increased ownership in the joint venture properties acquired as part of the Mills transaction, and favorable results of operations from the portfolio of joint venture properties.

            During the first quarter of 2012, we disposed of our interest in GCI for a gain of $28.8 million and acquired a controlling interest in nine properties previously accounted for under the equity method in the Mills transaction which resulted in the recognition of a non-cash gain of $488.7 million. In addition, we recorded an other-than-temporary impairment charge of $22.4 million on our remaining investment in SPG-FCM Ventures, LLC, or SPG-FCM, which holds our investment in TMLP, representing the excess of carrying value over the estimated fair value. During the six months ended June 30, 2011, we disposed of our interest in an unconsolidated mall and two of our other retail properties for an aggregate net gain of $13.8 million.

            Net income attributable to noncontrolling interests increased $96.3 million primarily due to an increase in the income of the Operating Partnership.

Liquidity and Capital Resources

            Because we generate revenues primarily from long-term leases, our financing strategy relies primarily on long-term fixed rate debt. We minimize the use of floating rate debt and enter into floating rate to fixed rate interest rate swaps. Floating rate debt currently comprises 9.5% of our total consolidated debt at June 30, 2012, as adjusted to reflect outstanding interest rate swaps. We also enter into interest rate protection agreements to manage our interest rate risk. We derive most of our liquidity from leases that generate positive net cash flow from operations and distributions of capital from unconsolidated entities that totaled $1.3 billion during the six months ended June 30, 2012. In addition, the Credit Facility and our $2.0 billion supplemental unsecured revolving credit facility, or Supplemental Facility, provide alternative sources of liquidity as our cash needs vary from time to time.

            Our balance of cash and cash equivalents decreased $160.2 million during the first six months of 2012 to $638.5 million as of June 30, 2012 as further discussed under "Cash Flows" below.

            On June 30, 2012, we had an aggregate available borrowing capacity of $3.9 billion under the Credit Facility and the Supplemental Facility, net of outstanding borrowings of $2.1 billion and letters of credit of $38.9 million. For the six months ended June 30, 2012, the maximum amount outstanding under the Credit Facility and Supplemental Facility was $3.1 billion and the weighted average amount outstanding was $1.6 billion. The weighted average interest rate was 1.28% for the six months ended June 30, 2012.

            We and the Operating Partnership have historically had access to public equity and long term unsecured debt markets and access to private equity from institutional investors at the property level.

            Our business model requires us to regularly access the debt markets to raise funds for acquisition, development and redevelopment activity, and to refinance maturing debt. We may also, from time to time, access the equity capital markets to accomplish our business objectives. We believe we have sufficient cash on hand and availability under the Credit Facility and the Supplemental Facility to address our debt maturities and capital needs through 2012.

Loan to SPG-FCM

            As discussed in Note 5 to the condensed notes to consolidated financial statements, the loan to SPG-FCM was extinguished in the Mills transaction. During the six month periods ended June 30, 2012 and 2011, we recorded $2.0 million and $4.9 million in interest income (net of inter-entity eliminations), related to this loan, respectively.

26

Cash Flows

            Our net cash flow from operating activities and distributions of capital from unconsolidated entities for the six months ended June 30, 2012 totaled $1.3 billion. In addition, we received net proceeds from our debt financing and repayment activities of $1.5 billion in 2012. These activities are further discussed below under "Financing and Debt." During the first six months of 2012, we or the Operating Partnership also:

•

issued 9,137,500 shares of common stock in a public offering for $1.2 billion, net of issue costs,

•

funded the acquisition of an additional interest in a property, the equity stake in Klépierre, additional interests in 26 joint venture properties in the Mills transaction and a 50% interest in an outlet center for $3.69 billion,

•

received proceeds of $375.8 million from the sale of our interest in GCI,

•

paid stockholder dividends and unitholder distributions totaling $701.5 million,

•

paid preferred stock dividends and preferred unit distributions totaling $2.6 million,

•

funded consolidated capital expenditures of $343.8 million (includes development and other costs of $85.1 million, renovation and expansion costs of $168.4 million, and tenant costs and other operational capital expenditures of $90.3 million), and

•

funded investments in unconsolidated entities of $117.1 million.

            In general, we anticipate that cash generated from operations will be sufficient to meet operating expenses, monthly debt service, recurring capital expenditures, and distributions to stockholders necessary to maintain our REIT qualification on a long-term basis. In addition, we expect to be able to obtain capital for nonrecurring capital expenditures, such as acquisitions, major building renovations and expansions, as well as for scheduled principal maturities on outstanding indebtedness, from:

•

excess cash generated from operating performance and working capital reserves,

•

borrowings on our credit facilities,

•

additional secured or unsecured debt financing, or

•

additional equity raised in the public or private markets.

            We expect to generate positive cash flow from operations in 2012, and we consider these projected cash flows in our sources and uses of cash. These cash flows are principally derived from rents paid by our retail tenants, many of whom are still recovering from the recent economic downturn. A significant deterioration in projected cash flows from operations could cause us to increase our reliance on available funds from our credit facilities, curtail planned capital expenditures, or seek other additional sources of financing as discussed above.

Financing and Debt

Unsecured Debt

            At June 30, 2012, our unsecured debt consisted of $12.3 billion of senior unsecured notes of the Operating Partnership, $1.8 billion outstanding under our Credit Facility, and $278.3 million outstanding under our Supplemental Facility. The June 30, 2012 balance on the Credit Facility included $1.1 billion (U.S. dollar equivalent) of Euro-denominated borrowings and the entire balance on the Supplemental Facility consisted of Yen-denominated borrowings, both of which are designated as net investment hedges of our international investments.

            On June 30, 2012, we had an aggregate available borrowing capacity of $3.9 billion under our credit facilities. The maximum outstanding balance of the credit facilities during the six months ended June 30, 2012 was $3.1 billion and the weighted average outstanding balance was $1.6 billion. Letters of credit of $38.9 million were outstanding under the Credit Facility as of June 30, 2012.

            The Credit Facility provides an initial borrowing capacity of $4.0 billion which can be increased at our option to $5.0 billion during its term. The Credit Facility will initially mature on October 30, 2015 and can be extended for an additional year at our sole option. The base interest rate on the Credit Facility is LIBOR plus 100 basis points with an additional facility fee of 15 basis points. In addition, the Credit Facility provides for a money market competitive bid option program that allows us to hold auctions to achieve lower pricing for short-term borrowings. The Credit Facility also includes a $2.0 billion multi-currency tranche.

27

            On June 1, 2012, we entered into a Supplemental Facility with an initial borrowing capacity of $2.0 billion that can be increased at our option to $2.5 billion during its term. The Supplemental Facility will initially mature on June 30, 2016 and can be extended for an additional year at our sole option. The base interest rate on the Supplemental Facility is LIBOR plus 100 basis points with an additional facility fee of 15 basis points. Like the Credit Facility, the Supplemental Facility provides for a money market competitive bid option program and allows for multi-currency borrowings. During the second quarter of 2012, we rolled $285.0 million (USD equivalent) of yen-denominated borrowings under the Credit Facility to the Supplemental Facility.

            On March 13, 2012, the Operating Partnership issued $600.0 million of senior unsecured notes at a fixed interest rate of 2.15% with a maturity date of September 2017, $600.0 million of senior unsecured notes at a fixed interest rate of 3.375% with a maturity date of March 2022, and $550.0 million of senior unsecured notes at a fixed interest rate of 4.75% with a maturity date of March 2042. Proceeds from the unsecured notes offerings were used to fund a portion of the cost of the acquisition of our equity stake in Klépierre and the Mills transaction.

            During the six months ended June 30, 2012, we redeemed at par $124.9 million of senior unsecured notes with fixed rates ranging from 5.75% to 6.88%.

            On November 1, 2011, we entered into an unsecured term loan with a $900.0 million borrowing capacity. We drew $160.0 million on the term loan in the first quarter of 2012. In the second quarter of 2012, we repaid the outstanding balance in full and terminated the term loan.

Secured Debt

            Total secured indebtedness was $8.0 billion and $6.8 billion at June 30, 2012 and December 31, 2011, respectively. During the six months ended June 30, 2012, we repaid $427.8 million in mortgage loans with a weighted average interest rate of 3.17%, unencumbering seven properties, and repaid a $735.0 million secured term loan in full.

            As a result of the acquisition of additional interests in properties in the Mills transaction in March 2012, as further discussed in Note 5 to the condensed consolidated notes to financial statements, we consolidated nine properties encumbered by property-level mortgage debt totaling $2.6 billion. This property-level mortgage debt was previously presented as debt of our unconsolidated entities. We and our joint venture partner had equal ownership in these properties prior to the transaction.

Covenants

            Our unsecured debt agreements contain financial covenants and other non-financial covenants. If we were to fail to comply with these covenants, after the expiration of the applicable cure periods, the debt maturity could be accelerated or other remedies could be sought by the lender including adjustments to the applicable interest rate. As of June 30, 2012, we are in compliance with all covenants of our unsecured debt.

            At June 30, 2012, we or our subsidiaries are the borrowers under 90 non-recourse mortgage notes secured by mortgages on 90 properties, including 8 separate pools of cross-defaulted and cross-collateralized mortgages encumbering a total of 38 properties. Under these cross-default provisions, a default under any mortgage included in the cross-defaulted pool may constitute a default under all mortgages within that pool and may lead to acceleration of the indebtedness due on each property within the pool. Certain of our secured debt contain financial and other non-financial covenants which are specific to the properties which serve as collateral for that debt. If the borrower fails to comply with these covenants, the lender could accelerate the debt and enforce its right against their collateral. At June 30, 2012, the applicable borrowers under these non-recourse mortgage notes were in compliance with all covenants where non-compliance individually, or giving effect to applicable cross-default provisions in the aggregate, could have a material adverse effect on our financial condition, results of operations or cash flows.

Summary of Financing

            Our consolidated debt, adjusted to reflect outstanding derivative instruments, and the effective weighted average interest rates as of June 30, 2012 and December 31, 2011, consisted of the following (dollars in thousands):

Debt Subject to	Adjusted Balance as of June 30, 2012		Effective Weighted Average Interest Rate			Adjusted Balance as of December 31, 2011		Effective Weighted Average Interest Rate
Fixed Rate	$	20,330,809		5.58	%	$	16,407,374		5.83	%
Variable Rate		2,135,749		1.74	%		2,039,066		1.45	%
	$	22,466,558		5.22	%	$	18,446,440		5.35	%

            As of June 30, 2012, we had $484.7 million of notional amount fixed rate swap agreements that have a weighted average fixed pay rate of 2.52% and a weighted average variable receive rate of 0.60% which effectively convert variable rate debt to fixed rate debt.

Contractual Obligations and Off-Balance Sheet Arrangements

            There have been no material changes to our outstanding capital expenditure and lease commitments previously disclosed in our 2011 Annual Report on Form 10-K.

            In regards to long-term debt arrangements, the following table summarizes the material aspects of these future obligations on our consolidated indebtedness as of June 30, 2012, for the remainder of 2012 and subsequent years thereafter (dollars in thousands) assuming the obligations remain outstanding through initial maturities:

	2012		2013-2014		2015-2017		After 2017		Total
Long-Term Debt(1)	$	248,105	$	3,396,916	$	11,491,174	$	7,243,489	$	22,379,684
Interest Payments(2)	$	572,034	$	2,051,043	$	2,005,752	$	2,306,447	$	6,935,276

(1)

Represents principal maturities only and therefore, excludes net premiums of $86,874.

(2)

Variable rate interest payments are estimated based on the LIBOR rate at June 30, 2012.

            Our off-balance sheet arrangements consist primarily of our investments in joint ventures which are common in the real estate industry and are described in Note 5 of the condensed notes to consolidated financial statements. Our joint ventures typically fund their cash needs through secured debt financings obtained by and in the name of the joint venture entity. The joint venture debt is secured by a first mortgage, is without recourse to the joint venture partners, and does not represent a liability of the partners, except to the extent the partners or their affiliates expressly guarantee the joint venture debt. As of June 30, 2012, the Operating Partnership had guaranteed $101.6 million of joint venture related mortgage or other indebtedness. We may elect to fund cash needs of a joint venture through equity contributions (generally on a basis proportionate to our ownership interests), advances or partner loans, although such funding is not required contractually or otherwise.

Acquisitions and Dispositions

            Buy-sell provisions are common in real estate partnership agreements. Most of our partners are institutional investors who have a history of direct investment in retail real estate. We or our partners in our joint venture properties may initiate these provisions (subject to any applicable lock up or similar restrictions). If we determine it is in our stockholders' best interests for us to purchase the joint venture interest and we believe we have adequate liquidity to execute the purchase without hindering our cash flows, then we may initiate these provisions or elect to buy. If we decide to sell any of our joint venture interests, we expect to use the net proceeds to reduce outstanding indebtedness or to reinvest in development, redevelopment, or expansion opportunities.

            Acquisitions.    On June 4, 2012, we acquired a 50% interest in a 465,000 square foot outlet center located in Destin, Florida for $70.5 million.

29

            On March 22, 2012, we acquired, through an acquisition of substantially all of the assets of TMLP, additional interests in 26 properties from our joint venture partner. The transaction resulted in 16 of the properties remaining unconsolidated, the consolidation of nine previously unconsolidated properties and the purchase of the remaining noncontrolling interest in a previously consolidated property. The transaction was valued at $1.5 billion, which included repayment of the remaining $562.1 million balance on TMLP's senior loan facility and retirement of $100.0 million of TMLP's trust preferred securities. In connection with the transaction, our $558.4 million loan to SPG-FCM was extinguished on a non-cash basis. We consolidated $2.6 billion in additional property-level mortgage debt in connection with this transaction. The transaction resulted in a remeasurement of our previously held interest in each of these properties to fair value and the recognition of a corresponding non-cash gain of approximately $488.7 million.

            On March 14, 2012, we acquired a 28.7% equity stake in Klépierre for approximately $2.0 billion. On May 21, 2012 Klépierre paid a dividend, which we elected to receive in additional shares, increasing our ownership to approximately 28.9%.

            On January 6, 2012, SPG-FCM, which holds our investment in TMLP, distributed its interest in Del Amo Fashion Center to SPG-FCM's joint venture partners. We purchased our venture partner's 25% interest for $50.0 million, which increased our ownership in the property to 50%. As a part of the transaction, we and our venture partner each contributed $50.0 million to SPG-FCM which was used to pay down TMLP's senior loan and the loan we made to SPG-FCM, as discussed above.

            On December 31, 2011, we and our joint venture partner dissolved a venture in which we had a 50% interest and distributed a portfolio of properties previously held within the venture to us and our joint venture partner. As a result, we have a 100% interest and now consolidate the six properties we received in the distribution. The distribution resulted in a remeasurement of the distributed assets to estimated fair value and a corresponding non-cash gain of $168.3 million in the fourth quarter of 2011 representing the estimated fair value of the assets received in excess of the carrying value of our interest in the joint venture portfolio.

            On August 25, 2011, we acquired additional controlling interests of approximately 83.75% in King of Prussia, thereby increasing our ownership interest to 96.1%. The property is subject to a $160.1 million mortgage. The consolidation of this previously unconsolidated property resulted in a remeasurement of our previously held interest to fair value and a corresponding non-cash gain of $82.9 million in the third quarter of 2011.

            Dispositions.    We continue to pursue the disposition of properties that no longer meet our strategic criteria or that are not a primary retail venue within their trade area.

            On May 3, 2012, we sold our investment in two residential apartment buildings located at The Domain in Austin, TX. Our share of the gain from the sale was $12.1 million, which is included in other income in the consolidated statements of operations and comprehensive income.

            During the first quarter of 2012, we sold one of our other retail properties with a carrying value of $115.0 million for nominal consideration and the assumption of the related mortgage debt of $115.0 million by the acquirer.

            On January 9, 2012, we sold our entire ownership interest in GCI to our venture partner, Auchan S.A. The aggregate cash we received was $375.8 million and we recognized a gain on the sale of $28.8 million.

Development Activity

            New Domestic Development.    On June 14, 2012, we opened Merrimack Premium Outlets, a 410,000 square foot upscale outlet shopping center located on a 170-acre site in Merrimack, New Hampshire, that serves the Greater Boston and Nashua markets. The total cost of this project was approximately $142.7 million, which was funded with available cash from operations.

            In July 2012, we began construction on St. Louis Premium Outlets located in Chesterfield, Missouri. We own a 60% interest in this project, which is a joint venture with Woodmont Outlets. This new center is expected to open in the fall of 2013. Our estimated share of the cost of this project is $49.4 million.

            In March 2012, we began construction on Phoenix Premium Outlets located in Phoenix, Arizona. This new center, which is wholly owned by us, is expected to open in May of 2013. The estimated cost of this project is $70.7 million.

30

            In August 2011, we began construction on Tanger Outlets — Galveston located in Texas City, Texas. This new center is a joint venture with Tanger Factory Outlets Centers, Inc. in which we have a 50% interest. Our estimated share of the cost of this project is $33.2 million.

            Domestic Expansions and Renovations.    We routinely incur costs related to construction for significant renovation and expansion projects at our properties. We also have reinstituted our redevelopment and expansion initiatives which we had previously reduced given the downturn in the economy. Renovation and expansion projects are currently underway at 25 properties in the U.S. and more than 70 anchor and big box tenants are currently scheduled to open in 2012 and 2013. We expect our share of development costs for 2012 related to renovation or expansion initiatives to be approximately $750.0 million compared to $265.0 million in 2011.

            We expect to fund these capital projects with cash flows from operations. Our estimated stabilized return on invested capital ranges between 8-12% for all of our new development, expansion and renovation projects.

            International Development Activity.    We typically reinvest net cash flow from our international joint ventures to fund future international development activity. We believe this strategy mitigates some of the risk of our initial investment and our exposure to changes in foreign currencies. We have also funded most of our foreign investments with local currency-denominated borrowings that act as a natural hedge against fluctuations in exchange rates. Currently, our consolidated net income exposure to changes in the volatility of the Euro, Yen, Won, and other foreign currencies is not material. We expect our share of international development costs for 2012 will be approximately $135 million at the applicable exchange rates, primarily funded through reinvested joint venture cash flow and construction loans.

            Rinku Premium Outlets Phase IV, a 103,000 square foot expansion to the Rinku Premium Outlets located in Osaka, Japan, was completed and opened in July 2012. Kobe-Sanda Premium Outlets Phase III, a 78,000 square foot expansion to the Kobe-Sanda Premium Outlets in Osaka, Japan, is under construction and is expected to open in December 2012. The net cost of these projects is expected to be JPY 5.7 billion, of which our share is approximately JPY 2.3 billion, or $28.7 million based on applicable YEN:USD exchange rates.

            In April 2012, construction began on Shisui Premium Outlets, a 234,000 square foot new development in Chiba, Japan, which is due to open in April 2013. The net cost of this project is expected to be JPY 9.2 billion, of which our share is approximately JPY 3.7 billion, or $46 million based on applicable YEN:USD exchange rates.

            In April 2012, construction began on Toronto Premium Outlets, a 358,000 square foot new development in Ontario, Canada, which is expected to open in August 2013. The net cost of this project is expected to be CAD 159.6 million, of which our share is approximately CAD 79.8 million, or $78.5 million based on applicable CAD:USD exchange rates.

            In 2012, construction began on Busan Premium Outlets, a 343,000 square foot new development in Busan, South Korea, which is due to open in September 2013. The net cost of this project is expected to be KRW 167.8 billion, of which our share is approximately KRW 83.9 billion, or $73.3 million based on applicable KRW:USD exchange rates.

            On March 1, 2012, we and our partner, Bailian Group, the largest retail conglomerate in China, announced the signing of a Memorandum of Understanding, or MOU, to jointly develop a Premium Outlet center in Pudong, Shanghai, China. The MOU also provides the joint venture the opportunity to develop additional Premium Outlet centers in mainland China.

            On April 9, 2012, we and our partner, BR Malls Participacoes S.A., signed a Joint Venture Agreement to develop and own Premium Outlet centers in Brazil in which we would have a 50% interest. The first Premium Outlet is expected to be opened in the State of Sao Paulo in 2013.

            On May 21, 2012, we and our partner, Calloway Real Estate Investment Trust, announced plans to develop a second Premium Outlet in Canada, which will be located in Montreal.

Dividends

            We paid a common stock dividend of $1.00 per share in the second quarter of 2012. On July 24, 2012, we announced a common stock dividend of $1.05 per share payable on August 31, 2012 to stockholders of record on August 17, 2012. We must pay a minimum amount of dividends to maintain our status as a REIT. Our dividends typically exceed our net income generated in any given year primarily because of depreciation, which is a non-cash

31

expense. Our future dividends and future distributions of the Operating Partnership will be determined by the Board of Directors based on actual results of operations, cash available for dividends and limited partner distributions, cash reserves as deemed necessary for capital and operating expenditures, and the amount required to maintain our status as a REIT.

Forward-Looking Statements

            Certain statements made in this section or elsewhere in this report may be deemed "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Although we believe the expectations reflected in any forward-looking statements are based on reasonable assumptions, we can give no assurance that our expectations will be attained, and it is possible that our actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks and uncertainties. Such factors include, but are not limited to: our ability to meet debt service requirements, the availability of financing, changes in our credit rating, changes in market rates of interest and foreign exchange rates for foreign currencies, the ability to hedge interest rate risk, risks associated with the acquisition, development and expansion of properties, general risks related to retail real estate, the liquidity of real estate investments, environmental liabilities, international, national, regional and local economic climates, changes in market rental rates, trends in the retail industry, relationships with anchor tenants, the inability to collect rent due to the bankruptcy or insolvency of tenants or otherwise, risks relating to joint venture properties, intensely competitive market environment in the retail industry, costs of common area maintenance, competitive market forces, risks related to our international investments and activities, insurance costs and coverage, terrorist activities, changes in economic and market conditions and maintenance of our status as a real estate investment trust. We discussed these and other risks and uncertainties under the heading "Risk Factors" in our most recent Annual Report on Form 10-K. We may update that discussion in our Quarterly Reports on Form 10-Q, but otherwise we undertake no duty or obligation to update or revise these forward-looking statements, whether as a result of new information, future developments, or otherwise.

Non-GAAP Financial Measures

            Industry practice is to evaluate real estate properties in part based on FFO, diluted FFO per share, NOI and comparable property NOI. We believe that these non-GAAP measures are helpful to investors because they are widely recognized measures of the performance of REITs and provide a relevant basis for comparison among REITs. We also use these measures internally to measure the operating performance of our portfolio.

            We determine FFO based on the definition set forth by the National Association of Real Estate Investment Trusts, or NAREIT, as consolidated net income computed in accordance with GAAP:

•

excluding real estate related depreciation and amortization,

•

excluding gains and losses from extraordinary items and cumulative effects of accounting changes,

•

excluding gains and losses from the sales of previously depreciated retail operating properties,

•

excluding impairment charges of depreciable real estate,

•

plus the allocable portion of FFO of unconsolidated entities accounted for under the equity method of accounting based upon economic ownership interest, and

•

all determined on a consistent basis in accordance with GAAP.

            We have adopted NAREIT's clarification of the definition of FFO that requires us to include the effects of nonrecurring items not classified as extraordinary, cumulative effect of accounting changes, or a gain or loss resulting from the sale of, or any impairment charges related to, previously depreciated operating properties.

            We include in FFO gains and losses realized from the sale of land, outlot buildings, marketable and non-marketable securities, and investment holdings of non-retail real estate.

32

            You should understand that our computations of these non-GAAP measures might not be comparable to similar measures reported by other REITs and that these non-GAAP measures:

•

do not represent cash flow from operations as defined by GAAP,

•

should not be considered as alternatives to consolidated net income determined in accordance with GAAP as a measure of operating performance, and

•

are not alternatives to cash flows as a measure of liquidity.

            The following schedule reconciles total FFO to consolidated net income and diluted net income per share to diluted FFO per share.

Item 3.    Qualitative and Quantitative Disclosures About Market Risk

            Sensitivity Analysis.    We disclosed a comprehensive qualitative and quantitative analysis regarding market risk in the Management's Discussion and Analysis of Financial Condition and Results of Operations included in our 2011 Annual Report on Form 10-K. There have been no material changes in the assumptions used or results obtained regarding market risk since December 31, 2011.

Item 4.    Controls and Procedures

            Evaluation of Disclosure Controls and Procedures.    We maintain disclosure controls and procedures (as defined in Rules 13a-15(e) under the Securities Exchange Act of 1934 (the "Exchange Act")) that are designed to provide reasonable assurance that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures. Because of inherent limitations, disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of disclosure controls and procedures are met.

            Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures are effective at a reasonable assurance level.

            Changes in Internal Control Over Financial Reporting.    There have not been any changes in our internal control over financial reporting (as defined in Rule 13a-15(f)) that occurred during the quarter ended June 30, 2012 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

35

Part II — Other Information

Item 1.    Legal Proceedings

            We are involved from time-to-time in various legal proceedings that arise in the ordinary course of our business, including, but not limited to commercial disputes, environmental matters, and litigation in connection with transactions including acquisitions and divestitures. We believe that such litigation, claims and administrative proceedings will not have a material adverse impact on our financial position or our results of operations. We record a liability when a loss is known or considered probable and the amount can be reasonably estimated.

Item 1A.    Risk Factors

            Through the period covered by this report, there were no significant changes to the Risk Factors disclosed in "Part 1: Business" of our 2011 Annual Report on Form 10-K.

Item 2.    Unregistered Sales of Equity Securities and Use of Proceeds

            During the quarter ended June 30, 2012, we issued 130,644 shares of common stock to limited partners in exchange for an equal number of units. The issuance of the shares of common stock was made pursuant to the terms of the Partnership Agreement of the Operating Partnership and was exempt from registration provided by Section 4(2) of the Securities Act of 1933, as amended.

            There were no reportable purchases of equity securities during the quarter ended June 30, 2012.

            We determine basic earnings per share based on the weighted average number of shares of common stock outstanding during the period and we consider any participating securities for purposes of applying the two-class method. We determine diluted earnings per share based on the weighted average number of shares of common stock outstanding combined with the incremental weighted average shares that would have been outstanding assuming all potentially dilutive common shares were converted into shares at the earliest date possible.

3.    Significant Accounting Policies

• Cash and Cash Equivalents

            We consider all highly liquid investments purchased with an original maturity of 90 days or less to be cash and cash equivalents. Cash equivalents are carried at cost, which approximates fair value. Cash equivalents generally consist of commercial paper, bankers' acceptances, Eurodollars, repurchase agreements, and money market deposits or securities. Financial instruments that potentially subject us to concentrations of credit risk include our cash and cash equivalents and our trade accounts receivable. We place our cash and cash equivalents with institutions with high credit quality. However, at certain times, such cash and cash equivalents are in excess of FDIC and SIPC insurance limits.

• Marketable and Non-Marketable Securities

            Marketable securities consist primarily of the investments of our captive insurance subsidiaries, available-for-sale securities, our deferred compensation plan investments, and certain investments held to fund the debt service requirements of debt previously secured by investment properties that have been sold.

            The types of securities included in the investment portfolio of our captive insurance subsidiaries typically include U.S. Treasury or other U.S. government securities as well as corporate debt securities with maturities ranging from less than 1 to 10 years. These securities are classified as available-for-sale and are valued based upon quoted market prices or other observable inputs when quoted market prices are not available. The amortized cost of debt securities, which approximates fair value, held by our captive insurance subsidiaries is adjusted for amortization of premiums and accretion of discounts to maturity. Changes in the values of these securities are recognized in accumulated other comprehensive income (loss) until the gain or loss is realized or until any unrealized loss is deemed to be other-than-temporary. We review any declines in value of these securities for other-than-temporary impairment and consider the severity and duration of any decline in value. To the extent an other-than-temporary impairment is deemed to have occurred, an impairment charge is recorded and a new cost basis is established. Subsequent changes are then recognized through other comprehensive income (loss) unless another other-than-temporary impairment is deemed to have occurred.

            Our investments in Capital Shopping Centres Group PLC, or CSCG, and Capital & Counties Properties PLC, or CAPC, are accounted for as available-for-sale securities. These investments are adjusted to their quoted market price, including a related foreign exchange component, with corresponding adjustment in other comprehensive income (loss). At June 30, 2012, we owned 35.4 million shares each of CSCG and of CAPC. At June 30, 2012, the market value of our investments in CSCG and CAPC was $178.8 million and $116.4 million, respectively, with an aggregate unrealized gain on these investments of $63.4 million. The market value of our investments in CSCG and CAPC at December 31, 2011 was $170.7 million and $100.9 million, respectively, with an aggregate unrealized gain of $39.7 million.

            Net unrealized gains recorded in other comprehensive income (loss) as of June 30, 2012 and December 31, 2011 were $65.7 million and $41.9 million, respectively, and represent the valuation and related currency adjustments for our marketable securities. As of June 30, 2012, we do not consider any of the declines in value of our marketable and non-marketable securities to be an other-than-temporary impairment, as these market value declines, if any, have existed for a short period of time, and, in the case of debt securities, we have the ability and intent to hold these securities to maturity.

            Our insurance subsidiaries are required to maintain statutory minimum capital and surplus as well as maintain a minimum liquidity ratio. Therefore, our access to these securities may be limited. Our deferred compensation plan investments are classified as trading securities and are valued based upon quoted market prices. The investments have a matching liability as the amounts are fully payable to the employees that earned the compensation. Changes in value of these securities and changes to the matching liability to employees are both recognized in earnings and, as a result, there is no impact to consolidated net income.

            As of June 30, 2012 and December 31, 2011, we also had investments of $24.9 million, which must be used to fund the debt service requirements of mortgage debt related to investment properties sold that previously collateralized the debt. These investments are classified as held-to-maturity and are recorded at amortized cost as we have the ability and intent to hold these investments to maturity.

            At June 30, 2012 and December 31, 2011, we had investments of $105.1 million in non-marketable securities that we account for under the cost method. We regularly evaluate these investments for any other-than-temporary impairment in their estimated fair value and determined that no adjustment in the carrying value was required.

• Loans Held for Investment

            From time to time, we may make investments in mortgage loans or mezzanine loans of third parties that own and operate commercial real estate assets located in the United States. Mortgage loans are secured, in part, by mortgages recorded against the underlying properties which are not owned by us. Mezzanine loans are secured, in part, by pledges of ownership interests of the entities that own the underlying real estate. Loans held for investment are carried at cost, net of any premiums or discounts which are accreted or amortized over the life of the related loan receivable utilizing the effective interest method. We evaluate the collectability of both interest and principal of each of these loans quarterly to determine whether the value has been impaired. A loan is deemed to be impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the existing contractual terms. When a loan is impaired, the amount of the loss accrual is calculated by comparing the carrying amount of the loan held for investment to its estimated realizable value.

            At June 30, 2012 and December 31, 2011, we had investments in mortgage and mezzanine loans with an aggregate carrying value of $86.4 million and $162.8 million, respectively. In April 2012, one of these mortgage loans with a principal balance of $76.8 million was repaid in its entirety. The remaining two loans held at June 30, 2012 mature in October 2012. One loan requires interest-only payments while the other requires payments of interest and principal based on a 30 year amortization schedule. Interest rates on these loans are fixed at 5.9% and 7.0% per annum, respectively, with a weighted average interest rate of 6.6% and approximate market rates for instruments of similar quality and duration. During the six months ended June 30, 2012 and June 30, 2011, we recorded $5.0 million and $13.9 million, respectively, in interest income earned from these loans. Payments on each of these loans were current as of June 30, 2012.

            On December 9, 2011, we paid consideration of $88.8 million to acquire a 50% equity interest in two real estate developments for which we are the construction lender. The loans primarily bear interest at 7.0% and mature in May and July 2013. At June 30, 2012 and December 31, 2011, the aggregate amount drawn on the loans was $106.9 million and $50.7 million, respectively. We consolidated these assets as of the date we acquired our equity interest and, accordingly, amounts drawn on the loans are eliminated in consolidation.

• Fair Value Measurements

            Level 1 fair value inputs are quoted prices for identical items in active, liquid and visible markets such as stock exchanges. Level 2 fair value inputs are observable information for similar items in active or inactive markets, and appropriately consider counterparty creditworthiness in the valuations. Level 3 fair value inputs reflect our best estimate of inputs and assumptions market participants would use in pricing an asset or liability at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate. We have no investments for which fair value is measured on a recurring basis using Level 3 inputs.

            We hold marketable securities that totaled $454.4 million and $417.0 million at June 30, 2012 and December 31, 2011, respectively, and are considered to have Level 1 fair value inputs. In addition, we have derivative instruments which are classified as having Level 2 inputs which consist primarily of interest rate swap agreements and foreign currency forward contracts with a gross liability balance of $6.6 million and $12.2 million at June 30, 2012 and December 31, 2011, respectively, and a gross asset value of $0.1 million and $14.9 million at June 30, 2012 and December 31, 2011, respectively. We also have interest rate cap agreements with nominal values.

            Note 6 includes a discussion of the fair value of debt measured using Level 1 and Level 2 inputs. Note 5 includes a discussion of the fair values recorded in purchase accounting and impairment, using Level 2 and Level 3 inputs. Level 3 inputs to our purchase accounting and impairment analyses include our estimations of net operating results of the property, capitalization rates and discount rates.

• Noncontrolling Interests and Temporary Equity

            Details of the carrying amount of our noncontrolling interests are as follows:

	As of June 30, 2012		As of December 31, 2011
Limited partners' interests in the Operating Partnership	$	1,186,052	$	953,622
Nonredeemable noncontrolling deficit interests in properties, net		(634)		(59,000)
Total noncontrolling interests reflected in equity	$	1,185,418	$	894,622

            The remaining interest in a property or portfolio of properties which are redeemable at the option of the holder or in circumstances that may be outside our control, are accounted for as temporary equity within limited partners' preferred interest in the Operating Partnership and noncontrolling redeemable interests in properties in the accompanying consolidated balance sheets. The carrying amount of the noncontrolling interest is adjusted to the redemption amount assuming the instrument is redeemable at the balance sheet date. Changes in the redemption value of the underlying noncontrolling interest are recorded within accumulated deficit. There are no noncontrolling interests redeemable at amounts in excess of fair value.

            Net income attributable to noncontrolling interests (which includes nonredeemable noncontrolling interests in consolidated properties, limited partners' interests in the Operating Partnership, redeemable noncontrolling interests in consolidated properties and preferred distributions payable by the Operating Partnership) is a component of consolidated net income. In addition, the individual components of other comprehensive income (loss) are presented in the aggregate for both controlling and noncontrolling interests, with the portion attributable to noncontrolling interests deducted from comprehensive income attributable to common stockholders.

            A rollforward of noncontrolling interests reflected in equity is as follows:

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2012		2011		2012		2011
Noncontrolling interests, beginning of period	$	1,215,628	$	771,152	$	894,622	$	802,972

Noncontrolling interests, end of period	$	1,185,418	$	773,894	$	1,185,418	$	773,894

• Derivative Financial Instruments

            We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. We use a variety of derivative financial instruments in the normal course of business to selectively manage or hedge a portion of the risks associated with our indebtedness and interest payments. Our objectives in using interest rate derivatives are to add stability to our interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps and caps. We require that hedging derivative instruments be highly effective in reducing the risk exposure that they are designated to hedge. As a result, there was no significant ineffectiveness from any of our derivative activities during the period. We formally designate any instrument that meets these hedging criteria, including borrowings in a foreign currency, as a hedge at the inception of the derivative contract. We have no credit-risk-related hedging or derivative activities.

            As of June 30, 2012, we had the following outstanding interest rate derivatives related to interest rate risk:

Interest Rate Derivative	Number of Instruments		Notional Amount
Interest Rate Swaps		3	$484.7 million
Interest Rate Caps		6	$444.4 million

            The carrying value of our interest rate swap agreements, at fair value, is a net liability balance of $6.2 million and $10.0 million at June 30, 2012 and December 31, 2011, respectively, and is included in other liabilities. The interest rate cap agreements were of nominal value at June 30, 2012 and December 31, 2011 and we generally do not apply hedge accounting to these arrangements.

            We are also exposed to fluctuations in foreign exchange rates on financial instruments which are denominated in foreign currencies, primarily in Japan and Europe. We use currency forward contracts and foreign currency denominated debt to manage our exposure to changes in foreign exchange rates on certain Yen and Euro-denominated receivables and net investments. Currency forward contracts involve fixing the Yen:USD or Euro:USD exchange rate for delivery of a specified amount of foreign currency on a specified date. The currency forward contracts are typically cash settled in US dollars for their fair value at or close to their settlement date. Approximately ¥4.9 billion remains as of June 30, 2012 for all forward contracts that we expect to receive through January 5, 2015. The June 30, 2012 net liability balance related to these forward contracts was $0.3 million, of which $0.4 million is included in other liabilities and $0.1 million is included in deferred costs and other assets. We have reported the changes in fair value for these forward contracts in earnings. The underlying currency adjustments on the foreign currency denominated receivables are also reported in income and generally offset the amounts in earnings for these forward contracts.

            In 2011, we entered into a Euro:USD forward contract with a €141.3 million notional value which was designated as a net investment hedge. The December 31, 2011 asset balance related to this forward was $14.9 million and is included in deferred costs and other assets. We apply hedge accounting and the change in fair value for this Euro forward contract is reflected in other comprehensive income. Changes in the value of this hedge are offset by changes in the underlying hedged Euro-denominated joint venture investment. In connection with the sale of our interest in Gallerie Commerciali Italia, S.p.A., or GCI, as further discussed in Note 5, this hedge was terminated in January 2012.

            The total gross accumulated other comprehensive loss related to our derivative activities, including our share of the other comprehensive loss from joint venture properties, approximated $102.5 million and $115.8 million as of June 30, 2012 and December 31, 2011, respectively.

2.    Basis of Presentation

            The accompanying unaudited consolidated financial statements include the accounts of all majority-owned subsidiaries, and all significant intercompany amounts have been eliminated. Due to the seasonal nature of certain operational activities, the results for the interim period ended June 30, 2012, are not necessarily indicative of the results to be expected for the full year.

            These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and include all of the information and disclosures required by accounting principles generally accepted in the United States (GAAP) for interim reporting. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments necessary for fair presentation (including normal recurring accruals) have been included. The consolidated financial statements in this Form 10-Q should be read in conjunction with the audited consolidated financial statements and related notes contained in our 2011 Annual Report on Form 10-K.

            As of June 30, 2012, we consolidated 228 wholly-owned properties and 18 additional properties that are less than wholly-owned, but which we control or for which we are the primary beneficiary. We account for the remaining 91 properties, or the joint venture properties, as well as our investment in Klépierre, using the equity method of accounting, as we have determined we have significant influence over their operations. We manage the day-to-day operations of 77 of the 91 joint venture properties, but have determined that our partner or partners have substantive participating rights with respect to the assets and operations of these joint venture properties. Our investments in joint ventures in Japan, South Korea, Malaysia, and Mexico comprise 12 of the remaining 14 joint venture properties. The international properties are managed locally by joint ventures in which we share oversight responsibility with our partner.

            We allocate net operating results of the Operating Partnership after preferred distributions to third parties and to us based on the partners' respective weighted average ownership interests in the Operating Partnership. Net operating results of the Operating Partnership attributed to third parties are reflected in net income attributable to noncontrolling interests. Our weighted average ownership interest in the Operating Partnership was 83.1% and 83.0% for the six months ended June 30, 2012 and 2011, respectively. As of June 30, 2012 and December 31, 2011, our ownership interest in the Operating Partnership was 83.3% and 82.8%, respectively. We adjust the noncontrolling limited partners' interests at the end of each period to reflect their interest in the Operating Partnership.

            Preferred distributions of the Operating Partnership are accrued at declaration and represent distributions on outstanding preferred units of partnership interests held by limited partners, or preferred units, and are included in net income attributable to noncontrolling interests.

• Reclassifications

            We made certain reclassifications of prior period amounts in the consolidated financial statements to conform to the 2012 presentation. These reclassifications had no impact on previously reported net income attributable to common stockholders or earnings per share.

7.    Equity

            During the first six months of 2012, we issued 221,109 shares of common stock to 16 limited partners in exchange for an equal number of units.

            On March 14, 2012, we issued 9,137,500 shares of common stock in a public offering at a price of $137.00 per share. Proceeds of $1.2 billion from the offering, net of issue costs, were used to fund a portion of the acquisition cost of our equity stake in Klépierre and the Mills transaction.

            On July 20, 2012, the Operating Partnership redeemed 2,000,000 units from a limited partner for $124.00 per unit in cash.

• Stock Based Compensation

            The Compensation Committee of our Board of Directors, or the Compensation Committee, awarded 12,034 shares of restricted stock to employees on March 5, 2012 and March 14, 2012 under The Simon Property Group, L.P. 1998 Stock Incentive Plan, or the Plan, at a fair market value of $138.41 per share and $141.12 per share, respectively. On June 1, 2012, our non-employee Directors were awarded 4,094 shares of restricted stock under the Plan at a fair market value of $143.51 per share as a result of their re-election to our Board. The fair market value of the restricted stock awarded on March 5, 2012 and March 14, 2012 is being recognized as expense over the three-year vesting service period. The fair market value of the restricted stock awarded on June 1, 2012 to our non-employee Directors is being recognized as expense over the one-year vesting service period.

            On March 16, 2010, the Compensation Committee of our Board approved three long-term incentive performance programs, or the 2010 LTIP programs, for certain senior executive officers. Awards under the 2010 LTIP programs take the form of LTIP units, a form of limited partnership interest issued by the Operating Partnership. During the performance period, participants are entitled to receive on the LTIP units awarded to them distributions equal to 10% of the regular quarterly distributions paid on a unit of the Operating Partnership. As a result, we account for these LTIP units as participating securities under the two-class method of computing earnings per share. Awarded LTIP units will be considered earned, in whole or in part, depending upon the extent to which the applicable total shareholder return, or TSR, benchmarks, as defined, are achieved during the performance period and, once earned, will become the equivalent of units after a two year service-based vesting period, beginning after the end of the performance period. Awarded LTIP units not earned are forfeited.

            The 2010 LTIP programs have one, two and three year performance periods, which end on December 31, 2010, 2011 and 2012, respectively. During July 2011, the Compensation Committee approved a three-year long-term incentive performance program, or the 2011-2013 LTIP program, and awarded LTIP units to certain senior executive officers. The 2011-2013 LTIP program has a three year performance period ending on December 31, 2013. During March 2012, the Compensation Committee approved a three-year long-term incentive performance program, or the 2012-2014 LTIP program, and awarded LTIP units to certain senior executive officers. The 2012-2014 LTIP program has a three year performance period ending December 31, 2014. After the end of each performance period, any earned LTIP units will then be subject to service-based vesting over a period of two years. One-half of the earned LTIP units will vest on January 1 of each of the second and third years following the end of the applicable performance period, subject to the participant maintaining employment with us through those dates.

            The 2010 LTIP program awards have an aggregate grant date fair value, adjusted for estimated forfeitures, of $7.2 million for the one-year program, $14.8 million for the two-year program and $23.0 million for the three-year program. The 2011-2013 LTIP program awards have an aggregate grant date fair value of $35.0 million, adjusted for estimated forfeitures. The 2012-2014 LTIP program awards have an aggregate grant date fair value of $35.0 million, adjusted for estimated forfeitures. Grant date fair values were estimated based upon the results of a Monte Carlo model, and the resulting expense will be recorded regardless of whether the TSR benchmarks are achieved. The grant date fair values are being amortized into expense over the period from the grant date to the date at which the awards, if any, become vested. In 2011, the Compensation Committee determined that 133,673 LTIP units were earned under the one-year 2010 LTIP program and, pursuant to the award agreements, will vest in two equal installments in 2012 and 2013. In the first quarter of 2012, the Compensation Committee determined that 337,006 LTIP units were earned under the two-year 2010 LTIP program and, pursuant to the award agreements, will vest in two equal installments in 2013 and 2014.

            On July 6, 2011, in connection with the execution of an employment agreement, the Compensation Committee granted David Simon, our Chairman and CEO, a retention award in the form of 1,000,000 LTIP units. The award vests in one-third increments on July 5^th of 2017, 2018 and 2019, subject to continued employment. The grant date fair value of the retention award was $120.3 million which is being recognized as expense over the eight-year term of his employment agreement on a straight-line basis.

6.    Debt

• Unsecured Debt

            At June 30, 2012, our unsecured debt consisted of $12.3 billion of senior unsecured notes of the Operating Partnership, $1.8 billion outstanding under our $4.0 billion unsecured revolving credit facility, or Credit Facility, and $278.3 million outstanding under our $2.0 billion supplemental unsecured revolving credit facility, or Supplemental Facility. The June 30, 2012 balance on the Credit Facility included $1.1 billion (U.S. dollar equivalent) of Euro-denominated borrowings and the entire balance on the Supplemental Facility on such date consisted of Yen-denominated borrowings, both of which are designated as net investment hedges of our international investments.

            On June 30, 2012, we had an aggregate available borrowing capacity of $3.9 billion under the two credit facilities. The maximum outstanding balance of the credit facilities during the six months ended June 30, 2012 was $3.1 billion and the weighted average outstanding balance was $1.6 billion. Letters of credit of $38.9 million were outstanding under the Credit Facility as of June 30, 2012.

            The Credit Facility's initial borrowing capacity of $4.0 billion can be increased at our option to $5.0 billion during its term. The Credit Facility will initially mature on October 30, 2015 and can be extended for an additional year at our sole option. The base interest rate on the Credit Facility is LIBOR plus 100 basis points with an additional facility fee of 15 basis points. In addition, the Credit Facility provides for a money market competitive bid option program that allows us to hold auctions to achieve lower pricing for short-term borrowings. The Credit Facility also includes a $2.0 billion multi-currency tranche.

            On June 1, 2012, we entered into a Supplemental Facility with an initial borrowing capacity of $2.0 billion which can be increased at our option to $2.5 billion during its term. The Supplemental Facility will initially mature on June 30, 2016 and can be extended for an additional year at our sole option. The base interest rate on the Supplemental Facility is LIBOR plus 100 basis points with an additional facility fee of 15 basis points. Like the Credit Facility, the Supplemental Facility provides for a money market competitive bid option program and allows for multi-currency borrowings. During the second quarter of 2012, we rolled $285.0 million (USD equivalent) of yen-denominated borrowings under the Credit Facility to the Supplemental Facility.

            On March 13, 2012, the Operating Partnership issued $600.0 million of senior unsecured notes at a fixed interest rate of 2.15% with a maturity date of September 2017, $600.0 million of senior unsecured notes at a fixed interest rate of 3.375% with a maturity date of March 2022, and $550.0 million of senior unsecured notes at a fixed interest rate of 4.75% with a maturity date of March 2042. Proceeds from the unsecured notes offerings were used to fund a portion of the cost of the acquisition of our equity stake in Klépierre and the Mills transaction.

            During the six months ended June 30, 2012, we redeemed at par $124.9 million of senior unsecured notes with fixed rates ranging from 5.75% to 6.88%.

            On November 1, 2011, we entered into a $900.0 million unsecured term loan. We drew $160.0 million on the term loan in the first quarter of 2012. In the second quarter of 2012, we repaid the outstanding balance in full and terminated the term loan.

• Secured Debt

            Total secured indebtedness was $8.0 billion and $6.8 billion at June 30, 2012 and December 31, 2011, respectively. During the six months ended June 30, 2012, we repaid $427.8 million in mortgage loans with a weighted average interest rate of 3.17%, unencumbering seven properties, and repaid the outstanding balance of a $735.0 million secured term loan in full.

            As a result of the acquisition of additional interests in properties in the Mills transaction in March 2012, as further discussed in Note 5, we consolidated nine properties encumbered by property-level mortgage debt totaling $2.6 billion. This property-level mortgage debt was previously presented as debt of our unconsolidated entities. We and our joint venture partner had equal ownership in these properties prior to the transaction.

• Covenants

            Our unsecured debt agreements contain financial covenants and other non-financial covenants. If we were to fail to comply with these covenants, after the expiration of the applicable cure periods, the debt maturity could be accelerated or other remedies could be sought by the lender including adjustments to the applicable interest rate. As of June 30, 2012, we are in compliance with all covenants of our unsecured debt.

            At June 30, 2012, we or our subsidiaries are the borrowers under 90 non-recourse mortgage notes secured by mortgages on 90 properties, including 8 separate pools of cross-defaulted and cross-collateralized mortgages encumbering a total of 38 properties. Under these cross-default provisions, a default under any mortgage included in the cross-defaulted pool may constitute a default under all mortgages within that pool and may lead to acceleration of the indebtedness due on each property within the pool. Certain of our secured debt contain financial and other non-financial covenants which are specific to the properties which serve as collateral for that debt. If the borrower fails to comply with these covenants, the lender could accelerate the debt and enforce its right against their collateral. At June 30, 2012, the applicable borrowers under these non-recourse mortgage notes were in compliance with all covenants where non-compliance individually, or giving effect to applicable cross-default provisions in the aggregate, could have a material adverse effect on our financial condition, results of operations or cash flows.

• Fair Value of Debt

            The carrying value of our variable-rate mortgages and other loans approximates their fair values. We estimate the fair values of consolidated fixed-rate mortgages using cash flows discounted at current borrowing rates and other indebtedness using cash flows discounted at current market rates. We estimate the fair values of consolidated fixed-rate unsecured notes using quoted market prices, or, if no quoted market prices are available, we use quoted market prices for securities with similar terms and maturities. The book value of our consolidated fixed-rate mortgages and other indebtedness was $19.8 billion and $15.9 billion as of June 30, 2012 and December 31, 2011, respectively. The fair values of these financial instruments and the related discount rate assumptions as of June 30, 2012 and December 31, 2011 are summarized as follows:

	June 30, 2012		December 31, 2011
Fair value of fixed-rate mortgages and other indebtedness	$	22,065	$17,905
Weighted average discount rates assumed in calculation of fair value for fixed-rate mortgages		3.51%	3.60%

Significant Accounting Policies

Cash and Cash Equivalents

• Cash and Cash Equivalents

            We consider all highly liquid investments purchased with an original maturity of 90 days or less to be cash and cash equivalents. Cash equivalents are carried at cost, which approximates fair value. Cash equivalents generally consist of commercial paper, bankers' acceptances, Eurodollars, repurchase agreements, and money market deposits or securities. Financial instruments that potentially subject us to concentrations of credit risk include our cash and cash equivalents and our trade accounts receivable. We place our cash and cash equivalents with institutions with high credit quality. However, at certain times, such cash and cash equivalents are in excess of FDIC and SIPC insurance limits.

Marketable and Non-Marketable Securities

• Marketable and Non-Marketable Securities

            Marketable securities consist primarily of the investments of our captive insurance subsidiaries, available-for-sale securities, our deferred compensation plan investments, and certain investments held to fund the debt service requirements of debt previously secured by investment properties that have been sold.

            The types of securities included in the investment portfolio of our captive insurance subsidiaries typically include U.S. Treasury or other U.S. government securities as well as corporate debt securities with maturities ranging from less than 1 to 10 years. These securities are classified as available-for-sale and are valued based upon quoted market prices or other observable inputs when quoted market prices are not available. The amortized cost of debt securities, which approximates fair value, held by our captive insurance subsidiaries is adjusted for amortization of premiums and accretion of discounts to maturity. Changes in the values of these securities are recognized in accumulated other comprehensive income (loss) until the gain or loss is realized or until any unrealized loss is deemed to be other-than-temporary. We review any declines in value of these securities for other-than-temporary impairment and consider the severity and duration of any decline in value. To the extent an other-than-temporary impairment is deemed to have occurred, an impairment charge is recorded and a new cost basis is established. Subsequent changes are then recognized through other comprehensive income (loss) unless another other-than-temporary impairment is deemed to have occurred.

            Our investments in Capital Shopping Centres Group PLC, or CSCG, and Capital & Counties Properties PLC, or CAPC, are accounted for as available-for-sale securities. These investments are adjusted to their quoted market price, including a related foreign exchange component, with corresponding adjustment in other comprehensive income (loss). At June 30, 2012, we owned 35.4 million shares each of CSCG and of CAPC. At June 30, 2012, the market value of our investments in CSCG and CAPC was $178.8 million and $116.4 million, respectively, with an aggregate unrealized gain on these investments of $63.4 million. The market value of our investments in CSCG and CAPC at December 31, 2011 was $170.7 million and $100.9 million, respectively, with an aggregate unrealized gain of $39.7 million.

            Net unrealized gains recorded in other comprehensive income (loss) as of June 30, 2012 and December 31, 2011 were $65.7 million and $41.9 million, respectively, and represent the valuation and related currency adjustments for our marketable securities. As of June 30, 2012, we do not consider any of the declines in value of our marketable and non-marketable securities to be an other-than-temporary impairment, as these market value declines, if any, have existed for a short period of time, and, in the case of debt securities, we have the ability and intent to hold these securities to maturity.

            Our insurance subsidiaries are required to maintain statutory minimum capital and surplus as well as maintain a minimum liquidity ratio. Therefore, our access to these securities may be limited. Our deferred compensation plan investments are classified as trading securities and are valued based upon quoted market prices. The investments have a matching liability as the amounts are fully payable to the employees that earned the compensation. Changes in value of these securities and changes to the matching liability to employees are both recognized in earnings and, as a result, there is no impact to consolidated net income.

            As of June 30, 2012 and December 31, 2011, we also had investments of $24.9 million, which must be used to fund the debt service requirements of mortgage debt related to investment properties sold that previously collateralized the debt. These investments are classified as held-to-maturity and are recorded at amortized cost as we have the ability and intent to hold these investments to maturity.

            At June 30, 2012 and December 31, 2011, we had investments of $105.1 million in non-marketable securities that we account for under the cost method. We regularly evaluate these investments for any other-than-temporary impairment in their estimated fair value and determined that no adjustment in the carrying value was required.

Loans Held for Investment

• Loans Held for Investment

            From time to time, we may make investments in mortgage loans or mezzanine loans of third parties that own and operate commercial real estate assets located in the United States. Mortgage loans are secured, in part, by mortgages recorded against the underlying properties which are not owned by us. Mezzanine loans are secured, in part, by pledges of ownership interests of the entities that own the underlying real estate. Loans held for investment are carried at cost, net of any premiums or discounts which are accreted or amortized over the life of the related loan receivable utilizing the effective interest method. We evaluate the collectability of both interest and principal of each of these loans quarterly to determine whether the value has been impaired. A loan is deemed to be impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the existing contractual terms. When a loan is impaired, the amount of the loss accrual is calculated by comparing the carrying amount of the loan held for investment to its estimated realizable value.

            At June 30, 2012 and December 31, 2011, we had investments in mortgage and mezzanine loans with an aggregate carrying value of $86.4 million and $162.8 million, respectively. In April 2012, one of these mortgage loans with a principal balance of $76.8 million was repaid in its entirety. The remaining two loans held at June 30, 2012 mature in October 2012. One loan requires interest-only payments while the other requires payments of interest and principal based on a 30 year amortization schedule. Interest rates on these loans are fixed at 5.9% and 7.0% per annum, respectively, with a weighted average interest rate of 6.6% and approximate market rates for instruments of similar quality and duration. During the six months ended June 30, 2012 and June 30, 2011, we recorded $5.0 million and $13.9 million, respectively, in interest income earned from these loans. Payments on each of these loans were current as of June 30, 2012.

            On December 9, 2011, we paid consideration of $88.8 million to acquire a 50% equity interest in two real estate developments for which we are the construction lender. The loans primarily bear interest at 7.0% and mature in May and July 2013. At June 30, 2012 and December 31, 2011, the aggregate amount drawn on the loans was $106.9 million and $50.7 million, respectively. We consolidated these assets as of the date we acquired our equity interest and, accordingly, amounts drawn on the loans are eliminated in consolidation.

Fair Value Measurements

• Fair Value Measurements

            Level 1 fair value inputs are quoted prices for identical items in active, liquid and visible markets such as stock exchanges. Level 2 fair value inputs are observable information for similar items in active or inactive markets, and appropriately consider counterparty creditworthiness in the valuations. Level 3 fair value inputs reflect our best estimate of inputs and assumptions market participants would use in pricing an asset or liability at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate. We have no investments for which fair value is measured on a recurring basis using Level 3 inputs.

            We hold marketable securities that totaled $454.4 million and $417.0 million at June 30, 2012 and December 31, 2011, respectively, and are considered to have Level 1 fair value inputs. In addition, we have derivative instruments which are classified as having Level 2 inputs which consist primarily of interest rate swap agreements and foreign currency forward contracts with a gross liability balance of $6.6 million and $12.2 million at June 30, 2012 and December 31, 2011, respectively, and a gross asset value of $0.1 million and $14.9 million at June 30, 2012 and December 31, 2011, respectively. We also have interest rate cap agreements with nominal values.

            Note 6 includes a discussion of the fair value of debt measured using Level 1 and Level 2 inputs. Note 5 includes a discussion of the fair values recorded in purchase accounting and impairment, using Level 2 and Level 3 inputs. Level 3 inputs to our purchase accounting and impairment analyses include our estimations of net operating results of the property, capitalization rates and discount rates.

Noncontrolling Interests and Temporary Equity

• Noncontrolling Interests and Temporary Equity

            Details of the carrying amount of our noncontrolling interests are as follows:

	As of June 30, 2012		As of December 31, 2011
Limited partners' interests in the Operating Partnership	$	1,186,052	$	953,622
Nonredeemable noncontrolling deficit interests in properties, net		(634)		(59,000)
Total noncontrolling interests reflected in equity	$	1,185,418	$	894,622

            The remaining interest in a property or portfolio of properties which are redeemable at the option of the holder or in circumstances that may be outside our control, are accounted for as temporary equity within limited partners' preferred interest in the Operating Partnership and noncontrolling redeemable interests in properties in the accompanying consolidated balance sheets. The carrying amount of the noncontrolling interest is adjusted to the redemption amount assuming the instrument is redeemable at the balance sheet date. Changes in the redemption value of the underlying noncontrolling interest are recorded within accumulated deficit. There are no noncontrolling interests redeemable at amounts in excess of fair value.

            Net income attributable to noncontrolling interests (which includes nonredeemable noncontrolling interests in consolidated properties, limited partners' interests in the Operating Partnership, redeemable noncontrolling interests in consolidated properties and preferred distributions payable by the Operating Partnership) is a component of consolidated net income. In addition, the individual components of other comprehensive income (loss) are presented in the aggregate for both controlling and noncontrolling interests, with the portion attributable to noncontrolling interests deducted from comprehensive income attributable to common stockholders.

            A rollforward of noncontrolling interests reflected in equity is as follows:

	For the Three Months Ended June 30,				For the Six Months Ended June 30,
	2012		2011		2012		2011

Derivative Financial Instruments

• Derivative Financial Instruments

            We record all derivatives on the balance sheet at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have elected to designate a derivative in a hedging relationship and apply hedge accounting and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. We use a variety of derivative financial instruments in the normal course of business to selectively manage or hedge a portion of the risks associated with our indebtedness and interest payments. Our objectives in using interest rate derivatives are to add stability to our interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps and caps. We require that hedging derivative instruments be highly effective in reducing the risk exposure that they are designated to hedge. As a result, there was no significant ineffectiveness from any of our derivative activities during the period. We formally designate any instrument that meets these hedging criteria, including borrowings in a foreign currency, as a hedge at the inception of the derivative contract. We have no credit-risk-related hedging or derivative activities.

            As of June 30, 2012, we had the following outstanding interest rate derivatives related to interest rate risk:

Interest Rate Derivative	Number of Instruments		Notional Amount
Interest Rate Swaps		3	$484.7 million
Interest Rate Caps		6	$444.4 million

            The carrying value of our interest rate swap agreements, at fair value, is a net liability balance of $6.2 million and $10.0 million at June 30, 2012 and December 31, 2011, respectively, and is included in other liabilities. The interest rate cap agreements were of nominal value at June 30, 2012 and December 31, 2011 and we generally do not apply hedge accounting to these arrangements.

            We are also exposed to fluctuations in foreign exchange rates on financial instruments which are denominated in foreign currencies, primarily in Japan and Europe. We use currency forward contracts and foreign currency denominated debt to manage our exposure to changes in foreign exchange rates on certain Yen and Euro-denominated receivables and net investments. Currency forward contracts involve fixing the Yen:USD or Euro:USD exchange rate for delivery of a specified amount of foreign currency on a specified date. The currency forward contracts are typically cash settled in US dollars for their fair value at or close to their settlement date. Approximately ¥4.9 billion remains as of June 30, 2012 for all forward contracts that we expect to receive through January 5, 2015. The June 30, 2012 net liability balance related to these forward contracts was $0.3 million, of which $0.4 million is included in other liabilities and $0.1 million is included in deferred costs and other assets. We have reported the changes in fair value for these forward contracts in earnings. The underlying currency adjustments on the foreign currency denominated receivables are also reported in income and generally offset the amounts in earnings for these forward contracts.

            In 2011, we entered into a Euro:USD forward contract with a €141.3 million notional value which was designated as a net investment hedge. The December 31, 2011 asset balance related to this forward was $14.9 million and is included in deferred costs and other assets. We apply hedge accounting and the change in fair value for this Euro forward contract is reflected in other comprehensive income. Changes in the value of this hedge are offset by changes in the underlying hedged Euro-denominated joint venture investment. In connection with the sale of our interest in Gallerie Commerciali Italia, S.p.A., or GCI, as further discussed in Note 5, this hedge was terminated in January 2012.

            The total gross accumulated other comprehensive loss related to our derivative activities, including our share of the other comprehensive loss from joint venture properties, approximated $102.5 million and $115.8 million as of June 30, 2012 and December 31, 2011, respectively.

8.    Commitments and Contingencies

• Litigation

            We are involved from time-to-time in various legal proceedings that arise in the ordinary course of our business, including, but not limited to commercial disputes, environmental matters, and litigation in connection with transactions including acquisitions and divestitures. We believe that such litigation, claims and administrative proceedings will not have a material adverse impact on our financial position or our results of operations. We record a liability when a loss is known or considered probable and the amount can be reasonably estimated.

            In May 2010, Opry Mills sustained significant flood damage. Insurance proceeds of $50 million have been funded by the insurers and remediation work has been completed. The property was re-opened March 29, 2012. The excess insurance carriers (those providing coverage above $50 million) have denied the claim under the policy for additional proceeds (of up to $150 million) to pay further amounts for restoration costs and business interruption losses. We and our lenders are continuing our efforts through pending litigation to recover our losses under the excess insurance policies for Opry Mills and we believe recovery is probable, but no assurances can be made that our efforts to recover these funds will be successful.

• Guarantees of Indebtedness

            Joint venture debt is the liability of the joint venture and is typically secured by the joint venture property, which is non-recourse to us. As of June 30, 2012 and December 31, 2011, the Operating Partnership guaranteed joint venture related mortgage or other indebtedness of $101.6 million and $30.2 million, respectively. Mortgages guaranteed by us are secured by the property of the joint venture and that property could be sold in order to satisfy the outstanding obligation.

• Concentration of Credit Risk

            Our malls, Premium Outlets, The Mills, and community/lifestyle centers rely heavily upon anchor retailers to attract customers; however anchor tenants do not contribute materially to our financial results as many anchor retailers own their spaces. All material operations are within the United States and no customer or tenant accounts for 5% or more of our consolidated revenues.

            On June 4, 2012, we acquired a 50% interest in a 465,000 square foot outlet center located in Destin, Florida for $70.5 million.

            On May 3, 2012, we sold our investment in two residential apartment buildings located at The Domain in Austin, TX. Our share of the gain from the sale is $12.1 million, which is included in other income in the consolidated statements of operations and comprehensive income.

            On March 22, 2012, as part of the Mills transaction discussed in Note 5, we acquired additional interests in 26 of our joint venture properties in a transaction valued at approximately $1.5 billion.

            On March 14, 2012, as discussed in Note 5, we acquired a 28.7% equity stake in Klépierre for approximately $2.0 billion, including the capitalization of acquisition costs.

            On January 9, 2012, as discussed in Note 5, we sold our entire ownership interest in GCI to our venture partner, Auchan S.A.

            On January 6, 2012, as discussed in Note 5, we purchased an additional 25% interest in Del Amo Fashion Center.

            During the first quarter of 2012, we sold one of our other retail properties with a carrying value of $115.0 million for nominal consideration and the assumption of the related mortgage debt of $115.0 million by the acquirer.

            On December 31, 2011, we and our joint venture partner dissolved a venture in which we had a 50% interest and distributed a portfolio of properties previously held within the venture to us and our joint venture partner. As a result, we have a 100% interest in and now consolidate the six properties we received in the distribution. The distribution resulted in a remeasurement of the distributed assets to estimated fair value and a corresponding non-cash gain of $168.3 million in the fourth quarter of 2011 representing the estimated fair value of the net assets received in excess of the carrying value of our interest in the joint venture portfolio. The asset and liability fair value allocation were recorded based on preliminary portfolio fair value estimates at the date of distribution and will be finalized during 2012.

            On August 25, 2011, we acquired additional controlling interests of approximately 83.75% in King of Prussia thereby increasing our ownership interest to 96.1%. The property is subject to a $160.1 million mortgage. The consolidation of this previously unconsolidated property resulted in a remeasurement of our previously held interest to fair value and a corresponding non-cash gain of $82.9 million in the third quarter of 2011.

            During the six months ended June 30, 2011, we disposed of our interests in two retail properties for a net gain of $7.2 million. Additionally on June 28, 2011, we sold one of our other retail properties for $134.0 million, resulting in a net gain of $6.6 million. These gains are included gain (loss) upon acquisition of controlling interests, sale or disposal of assets and interests in unconsolidated entities, and impairment charge on investment in unconsolidated entities, net in the accompanying consolidated statements of operations and comprehensive income.

            We expense acquisition and potential acquisition costs related to business combinations and disposition related costs as they are incurred. We incurred a minimal amount of transaction expenses during the six months ended June 30, 2012 and 2011.

5.    Investment in Unconsolidated Entities

• Real Estate Joint Ventures

            Joint ventures are common in the real estate industry. We use joint ventures to finance properties, develop new properties, and diversify our risk in a particular property or portfolio of properties. We held joint venture ownership interests in 79 properties in the United States as of June 30, 2012 and 87 properties as of December 31, 2011. At June 30, 2012, we also held interests in eight joint venture properties in Japan, two joint venture properties in South Korea, one joint venture property in Mexico, and one joint venture property in Malaysia. We account for these joint venture properties using the equity method of accounting. As discussed below, on January 9, 2012, we sold our interest in GCI which owns 45 properties located in Italy. Additionally, on March 14, 2012, we purchased a 28.7% equity stake in Klépierre. On May 21, 2012 Klépierre paid a dividend, which we elected to receive in additional shares, resulting in an increase in our ownership to approximately 28.9%.

            Certain of our joint venture properties are subject to various rights of first refusal, buy-sell provisions, put and call rights, or other sale or marketing rights for partners which are customary in real estate joint venture agreements and our industry. We and our partners in these joint ventures may initiate these provisions (subject to any applicable lock up or similar restrictions), which may result in either the sale of our interest or the use of available cash or borrowings, or the use of limited partnership interests in the Operating Partnership, to acquire the joint venture interest from our partner.

• Unconsolidated Property Transactions

            On January 6, 2012, SPG-FCM Ventures, LLC, or SPG-FCM, which holds our investment in The Mills Limited Partnership, or TMLP, distributed its interest in Del Amo Fashion Center to SPG-FCM's joint venture partners. We purchased our venture partner's 25% interest for $50.0 million, which increased our ownership in the property to 50%. As a part of the transaction, we and our venture partner each contributed $50.0 million to SPG-FCM which was used to pay down TMLP's senior loan and the loan we made to SPG-FCM, as discussed below.

            On March 22, 2012, we acquired, through an acquisition of substantially all of the assets of TMLP, additional interests in 26 properties, or the Mills transaction, from our joint venture partner. The transaction resulted in 16 of the properties remaining unconsolidated, the consolidation of nine previously unconsolidated properties and the purchase of the remaining noncontrolling interest in a previously consolidated property. The transaction was valued at $1.5 billion, which included repayment of the remaining $562.1 million balance on TMLP's senior loan facility, and retirement of $100.0 million of TMLP's trust preferred securities. In connection with the transaction, our $558.4 million loan to SPG-FCM was extinguished on a non-cash basis. We consolidated $2.6 billion in additional property-level mortgage debt in connection with this transaction. This property-level mortgage debt was previously presented as debt of our unconsolidated entities. We and our joint venture partner had equal ownership in these properties prior to the transaction.

            The consolidation of the previously unconsolidated properties resulted in a remeasurement of our previously held interest in each of these properties to fair value and recognition of a corresponding non-cash gain of $488.7 million. In addition, we recorded an other-than-temporary impairment charge of $22.4 million for the excess of carrying value of our remaining investment in SPG-FCM over its estimated fair value. The gain on the transaction and impairment charge are included in gain (loss) upon acquisition of controlling interests, sale or disposal of assets and interests in unconsolidated entities, and impairment charge on investment in unconsolidated entities, net in the accompanying consolidated statements of operations and comprehensive income. The assets and liabilities of the newly consolidated properties acquired in the Mills transaction have been reflected at their estimated fair value at the acquisition date, the majority of which, approximately $4.3 billion, was allocated to the investment property. This purchase price allocation is preliminary and is subject to revision within the measurement period, not to exceed one year from the date of acquisition.

            On December 31, 2011, as discussed in Note 9, we and our joint venture partner dissolved a venture in which we had a 50% interest and distributed a portfolio of properties previously held within the venture to us and our joint venture partner.

• Loan to SPG-FCM

            As discussed above, our loan to SPG-FCM was extinguished in the Mills transaction. During the six month periods ended June 30, 2012 and 2011, we recorded $2.0 million and $4.9 million in interest income (net of inter-entity eliminations), related to this loan, respectively. The loan bore interest at a rate of LIBOR plus 275 basis points.

• European Investments

            At June 30, 2012, we owned 57,634,148 shares, or approximately 28.9%, of Klépierre, which had a quoted market price of $32.80 per share. At the date of purchase on March 14, 2012, our excess investment in Klépierre was approximately $1.2 billion which we have allocated, on a preliminary basis, to the underlying investment property, other assets and liabilities based on estimated fair value. Our share of the results of Klépierre, net of the amortization of our excess investment, during our ownership period was nominal.

            Based on applicable Euro:USD exchange rates and after our conversion of Klépierre's results to GAAP, Klépierre's total revenues, operating income and consolidated net income were approximately $407.7 million, $154.4 million and $93.1 million, respectively, for the period of our ownership in 2012.

            At December 31, 2011, we had a 49% ownership interest in GCI. On January 9, 2012, we sold our entire ownership interest in GCI to our venture partner, Auchan S.A. The aggregate cash we received related to the sale of our interest GCI was $375.8 million and we recognized a gain on the sale of $28.8 million. Our investment carrying value included $39.5 million of accumulated losses related to currency translation and net investment hedge accumulated balances, which had been recorded in accumulated other comprehensive income (loss).

• Asian Joint Ventures

            We conduct our international Premium Outlet operations in Japan through a joint venture with Mitsubishi Estate Co., Ltd. We have a 40% ownership interest in this joint venture. The carrying amount of our investment in this joint venture was $335.9 million and $349.5 million as of June 30, 2012 and December 31, 2011, respectively, including all related components of accumulated other comprehensive income (loss). We conduct our international Premium Outlet operations in South Korea through a joint venture with Shinsegae International Co. We have a 50% ownership interest in this joint venture. The carrying amount of our investment in this joint venture was $58.3 million and $43.8 million as of June 30, 2012 and December 31, 2011, respectively, including all related components of accumulated other comprehensive income (loss).

Summary Financial Information

            A summary of our investments in joint ventures and share of income from our joint ventures, excluding Klépierre, follows. The statements of operations include amounts related to our investment in GCI, which was sold on January 9, 2012. In addition, we acquired additional controlling interests in The Plaza at King of Prussia and The Court at King of Prussia, or collectively, King of Prussia, on August 25, 2011 and nine properties in the Mills transaction on March 22, 2012. These previously unconsolidated properties became consolidated properties as of their respective acquisition dates. Additionally, on December 31, 2011, we and our joint venture partner dissolved a venture in which we had a 50% interest and distributed a portfolio of properties previously held within the venture to us and our joint venture partner. The results of operations of the properties for all of these transactions are classified as loss from operations of discontinued joint venture interests in the accompanying joint venture statements of operations. Balance sheet information for the joint ventures is as follows:

            "Excess Investment" represents the unamortized difference of our investment over our share of the equity in the underlying net assets of the joint ventures or other investments acquired and is allocated on a fair value basis primarily to investment property, lease related intangibles, and debt premiums and discounts. We amortize excess investment over the life of the related depreciable components of investment property, typically no greater than 40 years, the average remaining lease lives and the applicable debt maturity. The amortization is included in the reported amount of income from unconsolidated entities.
