1. Organization

            Simon Property Group, Inc., or Simon, is a Delaware corporation that operates as a self-administered and self-managed real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended. REITs will generally not be liable for federal corporate income taxes as long as they continue to distribute not less than 100% of their taxable income. 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, the Operating Partnership, and its subsidiaries.

            We own, develop and manage retail real estate properties, which consist primarily of malls, Premium Outlets®, and The Mills®. As of September 30, 2014, we owned or held an interest in 208 income-producing properties in the United States, which consisted of 112 malls, 68 Premium Outlets, 13 Mills, and 15 other shopping centers or outlet centers in 37 states and Puerto Rico. Internationally, as of September 30, 2014, we had ownership interests in nine Premium Outlets in Japan, three Premium Outlets in South Korea, one Premium Outlet in Canada, one Premium Outlet in Mexico, and one Premium Outlet in Malaysia. As of September 30, 2014, we had noncontrolling ownership interests in five outlet properties in Europe through our joint venture with McArthurGlen. Of the five properties, two are located in Italy and one each is located in Austria, the Netherlands, and the United Kingdom. Additionally, as of September 30, 2014, 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, shopping centers located in 13 countries in Europe.

            On May 28, 2014, as further discussed in Note 3, we completed the spin-off of our interests in 98 properties comprised of substantially all of our strip center business and our smaller enclosed malls to Washington Prime Group Inc., or Washington Prime, an independent, publicly traded REIT. The historical results of operations of the Washington Prime properties as well as the related assets and liabilities are presented as discontinued operations in the accompanying consolidated financial statements.

2. Basis of Presentation

            The accompanying unaudited consolidated financial statements include the accounts of all controlled 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 September 30, 2014, 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 2013 Annual Report on Form 10-K.

            As of September 30, 2014, we consolidated 134 wholly-owned properties and 13 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 81 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 58 of the 81 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, Canada, Mexico, Malaysia, and the five properties through our joint venture with McArthurGlen comprise 20 of the remaining 23 properties. The international properties are managed locally by joint ventures in which we share control.

            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. We allocate net operating results of the Operating Partnership after preferred distributions to limited partners and to us based on the partners' respective weighted average ownership interests in the Operating Partnership. Net operating results of the Operating Partnership attributable to limited partners are reflected in net income attributable to noncontrolling interests. Our weighted average ownership interest in the Operating Partnership was 85.5% and 85.6% for the nine months ended September 30, 2014 and 2013, respectively. As of September 30, 2014 and December 31, 2013, our ownership interest in the Operating Partnership was 85.5% and 85.7%, respectively. We adjust the noncontrolling limited partners' interests at the end of each period to reflect their interest in the Operating Partnership.

Reclassifications

            We made certain reclassifications of prior period amounts in the consolidated financial statements to conform to the 2014 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. At September 30, 2014, we had marketable securities of $463.6 million generally accounted for as available-for-sale which are adjusted to their quoted market price with a corresponding adjustment in other comprehensive income (loss). We recorded in other comprehensive income (loss) a net unrealized loss of $6.7 million as of September 30, 2014 and a net unrealized gain of $1.1 million as of December 31, 2013, which represent the valuation and related currency adjustments for our marketable securities.

            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.

            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.

            At September 30, 2014 and December 31, 2013, we had investments of $159.5 million and $118.8 million, respectively, 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.

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.

            The marketable securities we held at September 30, 2014 and December 31, 2013 were primarily classified as having Level 1 fair value inputs. In addition, we had derivative instruments which were 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 $1.2 million at December 31, 2013, and a gross asset value of $10.8 million and $8.4 million at September 30, 2014 and December 31, 2013, 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 2 inputs. Notes 5 and 9 include 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 include our estimations of net operating results of the property, capitalization rates and discount rates.

Noncontrolling Interests

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

            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 on its outstanding preferred units) 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:

Temporary Equity

            The remaining interests 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 each noncontrolling interest is adjusted to the redemption amount assuming the interest is redeemable at the balance sheet date.

            As discussed in Note 9, on January 10, 2014, we acquired one of our partner's redeemable interests in a portfolio of properties. During the second quarter of 2014, in connection with the resolution of all partnership disputes with related party limited partners in one of our partnerships, we contributed $83.0 million into the partnership in exchange for a new series of preferred partnership units that carry a 2.5% preferred return. Amounts due upon a future exercise of the limited partners' right to cause us to redeem their noncontrolling interests would be net of this preferred investment. Accordingly, this preferred investment contractually offsets the mezzanine liability previously recognized on the accompanying consolidated balance sheet.

            Changes in the redemption value of the underlying noncontrolling interest are recorded within accumulated deficit. If and to the extent the value of the redemption right exceeds the fair value of the limited partners' interests in the partnership, earnings available to common stockholders will be charged. There are no noncontrolling interests redeemable at amounts in excess of fair value at September 30, 2014.

Accumulated Other Comprehensive Income (Loss)

            The changes in accumulated other comprehensive income (loss) net of noncontrolling interest by component consisted of the following as of September 30, 2014:

            The reclassifications out of accumulated other comprehensive income (loss) consisted of the following as of September 30, 2014 and 2013:

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 designated a derivative as a hedge and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. We may 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 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 is no significant ineffectiveness from any of our derivative activities. We formally designate any instrument that meets these hedging criteria as a hedge at the inception of the derivative contract. We have no credit-risk-related hedging or derivative activities.

            As of September 30, 2014, we had no outstanding interest rate derivatives. The carrying value of our interest rate swap agreements, at fair value, as of December 31, 2013, was a net asset balance of $3.0 million, of which $0.4 million was included in other liabilities and $3.4 million was included in deferred costs and other assets. The interest rate caps were of nominal value at December 31, 2013 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 ¥41.9 million remains as of September 30, 2014 for all Yen forward contracts which mature through January 5, 2015. The September 30, 2014 asset balance related to these forward contracts was $0.2 million and 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 the third quarter of 2014, we entered into Euro:USD forward contracts, which were designated as net investment hedges, with an aggregate €150.0 million notional value which mature through August 11, 2017. The September 30, 2014 asset balance related to these forward contracts was $10.7 million and is included in deferred costs and other assets. In the fourth quarter of 2013, we entered into a Euro:USD forward contract with a €74.0 million notional value, which we designated as a net investment hedge, that matured on May 30, 2014. The liability balance related to this forward contract was $0.8 million and included in other liabilities as of December 31, 2013. We apply hedge accounting to these forward contracts and report the changes in fair value in other comprehensive income (loss). Changes in the value of these forward contracts are offset by changes in the underlying hedged Euro-denominated joint venture investment.

            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 $56.1 million and $61.8 million as of September 30, 2014 and December 31, 2013, respectively.

New Accounting Pronouncements

            In April 2014, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2014-08, "Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity." ASU 2014-08 changes the definition of a discontinued operation to include only those disposals of components of an entity that represent a strategic shift that has (or will have) a major effect on an entity's operations and financial results. ASU 2014-08 is effective prospectively for fiscal years beginning after December 15, 2014, but can be early-adopted. We early adopted ASU 2014-08 and are applying the revised definition to all disposals on a prospective basis, including the spin-off of Washington Prime as further discussed below. ASU 2014-08 also requires new disclosures of both discontinued operations and certain other disposals that do not meet the definition of a discontinued operation.

            In May 2014, the FASB issued ASU 2014-09, "Revenue From Contracts With Customers." ASU 2014-09 amends the existing accounting standards for revenue recognition and is based on principles that govern the recognition of revenue at an amount an entity expects to be entitled when products are transferred to customers. ASU 2014-09 will be effective for us beginning in its first quarter of 2017. Early adoption is not permitted. The new revenue standard may be applied retrospectively to each prior period presented or retrospectively with the cumulative effect recognized as of the date of adoption. We are currently evaluating the impact of adopting the new revenue standard on our consolidated financial statements.

Transaction Expenses

            We expense acquisition, potential acquisition and disposition related costs as they are incurred. We incurred $38.2 million in transaction costs during the first six months of 2014 related to the spin-off of Washington Prime. Other than these transaction costs, we incurred a minimal amount of transaction expenses during the nine months ended September 30, 2014 and 2013.

Discontinued Operations

            On May 28, 2014, we completed the spin-off of our interests in 98 properties comprised of substantially all of our strip center business and our smaller enclosed malls to Washington Prime, an independent, publicly traded REIT. The spin-off was effectuated through a distribution of the common shares of Washington Prime to holders of Simon common stock as of the distribution record date, and qualified as a tax-free distribution for U.S. federal income tax purposes. For every two shares of Simon common stock held as of the record date of May 16, 2014, Simon stockholders received one Washington Prime common share on May 28, 2014. At the time of the separation and distribution, Washington Prime owned a percentage of the outstanding units of partnership interest of Washington Prime Group, L.P. that was approximately equal to the percentage of outstanding units of partnership interest of the Operating Partnership, or units, owned by us. The remaining units of Washington Prime Group, L.P. were owned by limited partners of the Operating Partnership who received one Washington Prime Group, L.P. unit for every two units they owned in the Operating Partnership. Subsequent to the spin-off, we retained a nominal interest in Washington Prime Group, L.P. We also retained approximately $1.0 billion of proceeds from recently completed unsecured debt and mortgage debt as part of the spin-off.

            The historical results of operations of the Washington Prime properties have been presented as discontinued operations in the consolidated statements of operations and comprehensive income. Discontinued operations also include transaction costs of $38.2 million we incurred to spin-off Washington Prime. In addition, the assets and liabilities of Washington Prime are presented separately from assets and liabilities from continuing operations in the accompanying consolidated balance sheets. The accompanying consolidated statement of cash flows includes within operating, investing and financing cash flows those activities which related to our period of ownership of the Washington Prime properties.

            The results of the discontinued operations through the May 28, 2014 date of the spin-off are included in the consolidated results for the nine months ended September 30, 2014. Summarized financial information for discontinued operations for the three month period ended September 30, 2013, and nine month periods ended September 30, 2014 and 2013 is as follows (dollars in thousands).

            Capital expenditures on a cash basis (in millions) for the three month period ended September 30, 2013 were $24.7 million, and for the nine month periods ended September 30, 2014 and 2013 were $31.9 million and $67.2 million, respectively.

            We and Washington Prime entered into property management and transitional services agreements in connection with the spin-off whereby we will provide certain services to Washington Prime and its properties. Pursuant to the terms of the property management agreements, we manage, lease, and maintain Washington Prime's mall properties under the direction of Washington Prime. In exchange, Washington Prime pays us annual fixed rate property management fees ranging from 2.5% to 4.0% of base minimum and percentage rents, reimburses us for direct out-of-pocket costs and expenses and also pays us separate fees for any leasing and development services we provide. The property management agreements have an initial term of two years with automatic one year renewals unless terminated. Either party may terminate the property management agreements on or after the two-year anniversary of the spin-off upon 180 days prior written notice.

            We also provide certain support services to the Washington Prime strip centers and certain of its central functions to assist Washington Prime as it establishes its stand-alone processes for various activities that were previously provided by us and does not constitute significant continuing support of Washington Prime's operations. These services include assistance in the areas of information technology, treasury and financial management, payroll, lease administration, taxation and procurement. The charges for such services are intended to allow us to recover costs of providing these services. The transition services agreement will terminate no later than two years following the date of the spin-off subject to a minimum notice period equal to the shorter of 180 days or one-half of the original service period.

            Management and transitional services fees earned for the three and nine month periods ended September 30, 2014 were not significant.

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

            For the nine months ended September 30, 2014, potentially dilutive securities include 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. No securities had a dilutive effect for the nine months ended September 30, 2014. The only securities that had a dilutive effect for the nine months ended September 30, 2013 were stock options. We accrue dividends when they are declared.

5. Investment in Unconsolidated Entities

Real Estate Joint Ventures and Investments

            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. As discussed in Note 2, we held joint venture interests in 81 properties as of September 30, 2014.

            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 the 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.

            We may provide financing to joint ventures primarily in the form of interest bearing construction loans. As of September 30, 2014 and December 31, 2013, we had construction loans and other advances to related parties totaling $81.3 million and $140.3 million, respectively, which are included in deferred costs and other assets.

Unconsolidated Property Transactions

            On January 30, 2014, as discussed in Note 9, we acquired the remaining 50% interest in Arizona Mills from our joint venture partner. 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 $2.7 million in the first quarter of 2014. As a result of this acquisition, we now own 100% of this property.

            As discussed in Notes 1 and 3, on May 28, 2014, we completed the spin-off of Washington Prime, which included ten unconsolidated properties. The net income of these ten properties is included in income from operations of discontinued joint venture interests and the net assets and liabilities of these properties are included in the total assets and total liabilities of discontinued operations, respectively, in the accompanying summary financial information.

European Investments

            At September 30, 2014, we owned 57,634,148 shares, or approximately 28.9%, of Klépierre, which had a quoted market price of $44.00 per share. Our share of net income, net of amortization of our excess investment, was $138.7 million for the nine months ended September 30, 2014, which includes the disposal gain discussed below, and $23.8 million for the nine months ended September 30, 2013. 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 $949.9 million, $431.7 million and $1.3 billion, respectively, for the nine months ended September 30, 2014 and $1.1 billion, $538.6 million and $231.5 million, respectively, for the nine months ended September 30, 2013. On April 16, 2014, Klépierre completed the disposal of a portfolio of 126 retail galleries located in France, Spain and Italy. Total gross consideration for the transaction, including transfer duties, was €1.98 billion (€1.65 billion Klépierre's group share). The net cash proceeds were used by Klépierre to reduce its overall indebtedness. In connection with this transaction, we recorded a gain of $133.9 million, net of the write-off of a portion of our excess investment, which is included in "Gain upon acquisition of controlling interests and sale or disposal of assets and interest in unconsolidated entities, net" in the accompanying consolidated statements of operations and comprehensive income. On July 29, 2014 Klépierre announced that it had entered into a conditional agreement to acquire Corio N.V., or Corio, pursuant to which Corio shareholders will receive 1.14 Klépierre ordinary shares for each Corio ordinary share. The transaction, which is subject to shareholder approval, is expected to close in the first quarter of 2015.

            During the second quarter of 2013, we signed a definitive agreement with McArthurGlen, an owner, developer, and manager of designer outlets, to form one or more joint ventures to invest in certain existing designer outlets, development projects, and its property management and development companies. In conjunction with that agreement, we purchased a noncontrolling interest in the property management and development companies of McArthurGlen and a noncontrolling interest in a development property located in Vancouver, British Colombia. On August 2, 2013 we acquired a noncontrolling interest in Ashford Designer Outlet in Kent, UK. On October 16, 2013 we completed the remaining transactions contemplated by our previously announced definitive agreement with McArthurGlen by acquiring noncontrolling interests in portions of four existing McArthurGlen Designer Outlets — Parndorf (Vienna, Austria), La Reggia (Naples, Italy), Noventa di Piave (Venice, Italy), and Roermond (Roermond, Netherlands). During the quarter ended June 30, 2014, through our joint venture with McArthurGlen, we purchased an additional 22.5% noncontrolling interest in Ashford Designer Outlet, increasing our ownership interest in this property to 45%. At September 30, 2014, our legal ownership interests in these properties range from 45% to 90%. The aggregate consideration for the 2013 transactions was $496.7 million and is subject to further adjustment based upon contractual obligations and customary purchase price adjustments. The carrying amount of our investment in these joint ventures, including all related components of accumulated other comprehensive income (loss) as well as subsequent capital contributions for development, was $678.1 million and $510.7 million as of September 30, 2014 and December 31, 2013, respectively. The change in the carrying amount of the investment in 2014 was driven by the additional investment discussed above and adjustments to our preliminary purchase accounting including our estimate of the aggregate consideration. Substantially all of our investment has been deemed excess investment and has been preliminarily allocated to the underlying investment property based on estimated fair values. The preliminary allocations are subject to revision within the measurement period, not to exceed one year from the date of the acquisitions.

            We also have a minority interest in Value Retail PLC, which owns and operates nine luxury outlets throughout Europe and an additional direct minority ownership in three of those outlets. Our investment in these centers is accounted for under the cost method. At September 30, 2014 and December 31, 2013, the carrying value of these investments was $115.4 million and is included in deferred costs and other assets.

6. Debt

Unsecured Debt

            At September 30, 2014, our unsecured debt consisted of $13.8 billion of senior unsecured notes of the Operating Partnership, net of discounts, $606.6 million outstanding under the Operating Partnership's $4.0 billion unsecured revolving credit facility, or Credit Facility, $203.5 million outstanding under the Operating Partnership's $2.0 billion supplemental unsecured revolving credit facility, or Supplemental Facility, and $240.0 million outstanding under an unsecured term loan. At September 30, 2014, the Credit Facility had a capacity of $4.0 billion including a $2.0 billion multi-currency tranche, an initial maturity of June 30, 2018, an interest rate of LIBOR plus 80 basis points and an additional facility fee of 10 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 entire balance on the Credit Facility at September 30, 2014 consisted 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 September 30, 2014, we had an aggregate available borrowing capacity of $5.2 billion under the two credit facilities. The maximum outstanding balance of the credit facilities during the nine months ended September 30, 2014 was $1.2 billion and the weighted average outstanding balance was $900.9 million. Letters of credit of $39.0 million were outstanding under the two credit facilities as of September 30, 2014.

            On April 7, 2014, the Operating Partnership amended and extended the Credit Facility. The initial borrowing capacity of $4.0 billion may be increased to $5.0 billion during its term and provides for borrowings denominated in U.S. Dollars, Euros, Yen, Sterling, Canadian Dollars and Australian Dollars. Borrowings in currencies other than the U.S. Dollar are limited to 75% of the maximum revolving credit amount, as defined. The initial maturity date was extended to June 30, 2018 and can be extended for an additional year at our sole option to a final maturity date of June 30, 2019. The base interest rate on the amended Credit Facility was reduced to LIBOR plus 80 basis points and the additional facility fee was reduced to 10 basis points.

            The Supplemental Facility's borrowing capacity of $2.0 billion may be increased 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. As of September 30, 2014, the base interest rate on the Supplemental Facility was LIBOR plus 95 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.

            On September 3, 2014, the Operating Partnership commenced cash tender offers for any and all of five series of our outstanding senior unsecured notes with maturity dates ranging from 2015 to 2017. The total principal amount of notes tendered and accepted for purchase was approximately $1.322 billion, with a weighted average remaining duration of 1.7 years and a weighted average coupon rate of 5.60%. The Operating Partnership purchased the tendered notes using cash on hand and the proceeds from an offering of $1.3 billion of senior unsecured notes that closed on September 10, 2014. The senior notes offering was comprised of $900.0 million of 3.375% notes due 2024 and $400.0 million of 4.25% notes due 2044. Combined, the new issues of senior notes have a weighted average duration of 16.1 years and a weighted average coupon rate of 3.64%. Proceeds from the senior notes offering were also used to fund the redemption on September 30, 2014 of all $250.0 million outstanding principal amount of the 7.875% notes due 2016 issued by one of our subsidiaries. We recorded a $127.6 million loss on extinguishment of debt in the third quarter of 2014 as a result of the tender offers and redemption.

            On January 21, 2014, the Operating Partnership issued $600.0 million of senior unsecured notes at a fixed interest rate of 2.20% with a maturity date of February 1, 2019 and $600.0 million of senior unsecured notes at a fixed interest rate of 3.75% with a maturity date of February 1, 2024. Proceeds from the unsecured notes offering were used to repay debt and for general corporate purposes.

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

            In addition to the tender offers and redemption described above, during the nine months ended September 30, 2014, we used cash on hand to redeem at par or repay at maturity $934.5 million of senior unsecured notes with fixed rates ranging from 4.90% to 6.75%.

            On October 6, 2014, the Operating Partnership entered into a global unsecured commercial paper note program. Under the terms of this program, the Operating Partnership may issue unsecured commercial paper notes, denominated in U.S. dollars, Euros and other currencies, up to a maximum aggregate amount outstanding at any time of $500.0 million, or the non-U.S. equivalent thereof. Notes issued in non-U.S. currencies may be issued by one or more subsidiaries of the Operating Partnership and are guaranteed by the Operating Partnership. Notes will be sold under customary terms in the U.S and Euro commercial paper note markets and will rank (either by themselves or as a result of the guarantee described above) pari passu with all of the Operating Partnership's other unsecured senior indebtedness.

Mortgage Debt

            Total mortgage indebtedness was $6.3 billion and $7.3 billion at September 30, 2014 and December 31, 2013, respectively.

            On January 2, 2014, we repaid the $820.0 million outstanding mortgage at Sawgrass Mills originally maturing July 1, 2014 and on February 28, 2014, we repaid the $269.0 million outstanding mortgage at Great Mall originally maturing August 28, 2015. During the third quarter of 2014, we disposed of our interests in two retail properties and their related mortgage debt of $48.4 million.

Covenants

            Our unsecured debt agreements contain financial and other 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 September 30, 2014, we were in compliance with all covenants of our unsecured debt.

            At September 30, 2014, we or our subsidiaries are the borrowers under 39 non-recourse mortgage notes secured by mortgages on 53 properties, including five separate pools of cross-defaulted and cross-collateralized mortgages encumbering a total of 21 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 instruments 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 September 30, 2014, the applicable borrowers under these non-recourse mortgage notes were in compliance with all covenants where non-compliance could individually, or giving effect to applicable cross-default provisions in the aggregate, 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 unsecured indebtedness was $19.5 billion and $20.9 billion as of September 30, 2014 and December 31, 2013, respectively. The fair

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

values of these financial instruments and the related discount rate assumptions as of September 30, 2014 and December 31, 2013 are summarized as follows:

7. Equity

            During the nine months ended September 30, 2014, we issued 64,129 shares of common stock to five limited partners of the Operating Partnership in exchange for an equal number of units pursuant to the partnership agreement of the Operating Partnership.

            On January 30, 2014, the Operating Partnership issued 555,150 units in connection with the acquisition of the remaining 50% interest in Arizona Mills and approximately 39 acres of land in Oyster Bay, New York, as discussed in Note 9.

            On July 22, 2014, the Operating Partnership redeemed 87,621 units from a limited partner for $14.4 million.

Stock Based Compensation

            Awards under our stock based compensation plans primarily take the form of LTIP units and restricted stock grants made under The Simon Property Group, L.P. 1998 Stock Incentive Plan, or the Plan. Restricted stock and awards under the LTIP programs are all performance based and are based on various corporate and business unit performance measures as further described below. The expense related to these programs, net of amounts capitalized, is included within home and regional office costs and general and administrative costs in the accompanying consolidated statements of operations and comprehensive income.

            LTIP Programs.    Every year since 2010, the Compensation Committee of the Board of Directors, or Compensation Committee, has approved long-term, performance based incentive compensation programs, or the LTIP programs, for certain senior executive officers. Awards under the LTIP programs take the form of LTIP units, a form of limited partnership interest issued by the Operating Partnership, and will be considered earned if, and only to the extent to which, applicable total shareholder return, or TSR, performance measures are achieved during the performance period. Once earned, LTIP units are subject to a two year vesting period. One-half of the earned LTIP units will vest on January 1 of each of the 2nd and 3rd years following the end of the applicable performance period, subject to the participant maintaining employment with us through those dates and certain other conditions as described in those agreements. Awarded LTIP units not earned are forfeited. Earned and fully vested LTIP units are the equivalent of units. During the performance period, participants are entitled to receive distributions on the LTIP units awarded to them 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.

            From 2010 to 2014, the Compensation Committee approved LTIP grants as shown in the table below. Grant date fair values of the LTIP units are estimated using a Monte Carlo model, and the resulting expense is recorded regardless of whether the TSR performance measures are achieved if the required service is delivered. 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, would become

vested. The extent to which LTIP units were earned, and the aggregate grant date fair values adjusted for estimated forfeitures, are as follows:

            We recorded compensation expense, net of capitalization, related to these LTIP programs of approximately $20.3 million and $19.0 million for the nine months ended September 30, 2014 and 2013, respectively.

            Restricted Stock.    The Compensation Committee awarded 1,246 and 62,565 shares of restricted stock to employees on February 26, 2014 and April 1, 2014, respectively, under the Plan, at a fair market value of $161.06 per share and $164.92 per share, respectively. On May 27, 2014, our non-employee Directors were awarded 3,570 shares of restricted stock under the Plan at a fair market value of $176.55 per share. The fair market value of the employee restricted stock awards is being recognized as expense over the three-year vesting service period. The fair market value of the Director restricted stock awards is being recognized as expense over the one-year vesting service period.

            On August 26, 2014, the Compensation Committee awarded 17,000 shares of restricted stock to an employee under the Plan at a fair market value of $169.25 per share. The fair market value of this employee restricted stock award is being recognized as expense over the four-year vesting period.

            We recorded compensation expense, net of capitalization, related to restricted stock of approximately $9.8 million for both the nine months ended September 30, 2014 and 2013.

            Other Compensation Arrangements.    On July 6, 2011, in connection with the execution of an eight year employment agreement, the Compensation Committee granted David Simon, Simon's Chairman and CEO, a retention award in the form of 1,000,000 LTIP units (the "Award") for his continued service as Simon's Chairman and Chief Executive Officer through July 5, 2019. Effective December 31, 2013, the Award was modified ("Current Award") and as a result the LTIP units will now become earned and eligible to vest based on the attainment of company-based performance goals, in addition to the service-based vesting requirement included in the original Award. If the relevant performance criteria are not achieved, all or a portion of the Current Award will be forfeited. The Current Award does not contain an opportunity for Mr. Simon to receive additional LTIP Units above and beyond the original Award should Simon's performance exceed the higher end of the performance criteria. The performance criteria of the Current Award are based on the attainment of specific funds from operations ("FFO") per share. If the performance criteria have been met, a maximum of 360,000 LTIP units ("A Units"), 360,000 LTIP units ("B Units") and 280,000 LTIP units ("C Units") may become earned December 31, 2015, 2016 and 2017, respectively. The earned A Units will vest on January 1, 2018, earned B Units will vest on January 1, 2019 and earned C Units will vest on June 30, 2019, subject to Mr. Simon's continued employment through such applicable date. The grant date fair value of the retention award of $120.3 million is being recognized as expense over the eight-year term of his employment agreement on a straight-line basis based through the applicable vesting periods of the A Units, B Units and C Units.

Changes in Equity

            The following table provides a reconciliation of the beginning and ending carrying amounts of total equity, equity attributable to common stockholders and equity attributable to noncontrolling interests:

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 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, 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 our 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 September 30, 2014 and December 31, 2013, the Operating Partnership guaranteed joint venture related mortgage indebtedness of $226.2 million and $190.8 million, respectively (of which we have a right of recovery from our joint venture partners of $80.5 million and $83.0 million, respectively). Mortgages guaranteed by us are secured by the property of the joint venture which could be sold in order to satisfy the outstanding obligation and which has an estimated fair value in excess of the guaranteed amount.

Concentration of Credit Risk

            Our U.S. Malls, Premium Outlets, and The Mills rely heavily upon anchor tenants to attract customers; however anchor retailers 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

            During the third quarter of 2014, we disposed of our interests in two consolidated retail properties. The aggregate gain recognized on these transactions was approximately $17.7 million. Also, during the third quarter of 2014, we sold our investment in a hotel located at Coconut Point in Estero, Florida. Our share of the gain from this sale was $4.4 million, which is included in other income in the consolidated statements of operations and comprehensive income.

            On September 16, 2014, we entered into a definitive agreement under which we will acquire Jersey Gardens in Elizabeth, New Jersey and University Park Village in Fort Worth, Texas, properties currently owned by Glimcher Realty Trust, or Glimcher, for an aggregate cash purchase price of $1.09 billion. This acquisition will close concurrently with, and is subject to, the closing of the acquisition of Glimcher by Washington Prime, which is expected to occur in the first quarter of 2015.

            On April 10, 2014, as discussed further in Note 5, we acquired an additional noncontrolling interest in Ashford Designer Outlet.

            On January 30, 2014, we acquired the remaining 50% interest in Arizona Mills from our joint venture partner, as well as approximately 39 acres of land in Oyster Bay, New York, for approximately $145.8 million, consisting of cash consideration and 555,150 units of the Operating Partnership. Arizona Mills is subject to a mortgage which was $166.9 million at the time of the acquisition. 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 $2.7 million in the first quarter of 2014. We now own 100% of this property.

            On January 10, 2014, we acquired one of our partner's redeemable interests in a portfolio of ten properties for approximately $114.4 million subject to a pre-existing contractual arrangement. The amount paid to acquire the interests in the seven properties which were previously consolidated was included in limited partners' preferred interest in the Operating Partnership and noncontrolling redeemable interests in properties at December 31, 2013.

            During the first quarter of 2013, we acquired rights to the remaining interests in three unconsolidated community centers and subsequently disposed of our interests in those properties. Additionally, we disposed of our interest in another community center. The aggregate gain recognized on these transactions was approximately $20.8 million. Of this gain, $14.2 million is included within discontinued operations.

            During 2013, as further discussed in Note 5, we acquired noncontrolling interests in the property management and development companies of McArthurGlen as well as interests in five designer outlet properties.

            On May 30, 2013 we acquired a 100% interest in a 390,000 square foot outlet center located near Portland, Oregon for cash consideration of $146.7 million. The fair value of the acquisition was recorded primarily as investment property and lease related intangibles. As a result of the excess of fair value over amounts paid, we recognized a gain of approximately $27.3 million.

            Unless otherwise noted, gains and losses on the above transactions are included in gain upon acquisition of controlling interests and sale or disposal of assets and interests in unconsolidated entities, net in the accompanying consolidated statements of operations and comprehensive income.

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

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

Overview

            Simon Property Group, Inc., or Simon, is a Delaware corporation that operates as a self-administered and self-managed real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended. REITs will generally not be liable for federal corporate income taxes as long as they continue to distribute not less than 100% of their taxable income. 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 this discussion, the terms "we", "us" and "our" refer to Simon, the Operating Partnership, and its subsidiaries.

            We own, develop and manage retail real estate properties, which consist primarily of malls, Premium Outlets®, and The Mills®. As of September 30, 2014, we owned or held an interest in 208 income-producing properties in the United States, which consisted of 112 malls, 68 Premium Outlets, 13 Mills, and 15 other shopping centers or outlet centers in 37 states and Puerto Rico. We have several Premium Outlets under development and have redevelopment and expansion projects, including the addition of anchors and big box tenants, underway at more than 30 properties in the U.S., Asia, and Mexico. Internationally, as of September 30, 2014, we had ownership interests in nine Premium Outlets in Japan, three Premium Outlets in South Korea, one Premium Outlet in Canada, one Premium Outlet in Mexico, and one Premium Outlet in Malaysia. As of September 30, 2014, we had noncontrolling ownership interests in five outlet properties in Europe through our joint venture with McArthurGlen. Of the five properties, two are located in Italy and one each is located in Austria, the Netherlands, and the United Kingdom. Additionally, as of September 30, 2014, 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, shopping centers located in 13 countries in Europe.

            On May 28, 2014, as further discussed in Note 3 to the condensed notes to consolidated financial statements, we completed the spin-off of our interests in 98 properties comprised of substantially all of our strip center business and our smaller enclosed malls to Washington Prime Group Inc., or Washington Prime, an independent, publicly traded REIT. The historical results of operations of the Washington Prime properties as well as the related assets and liabilities are presented as discontinued operations in the accompanying consolidated financial statements.

            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



•

recoverable expenditures such as 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,



•

selling or leasing land adjacent to our 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 redevelop 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 markets we believe are not adequately served by existing retail outlets.

            We routinely review and evaluate acquisition opportunities based on their ability to enhance 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 internally to evaluate the operating 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 $0.21 during the first nine months of 2014 to $3.22 from $3.01 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 2014 and the impact of our acquisition and expansion activity,



•

decreased interest expense in 2014 as further discussed below,



•

increased lease settlement and land sale activity as further discussed below, and



•

a 2014 gain on acquisitions and disposals of $154.5 million, or $0.43 per diluted share, primarily related to Klépierre's sale of a portfolio of 126 retail galleries of which our share was $136.5 million, or $0.38 per diluted share,



•

partially offset by 2013 gains of $99.9 million, or $0.28 per diluted share, due to the sale or disposal of our interest in nine properties and the acquisition of a controlling interest in an outlet center,



•

the loss of $68.3 million of net income attributed to the discontinued operations of Washington Prime, or $0.19 per diluted share, along with transaction expenses related to the spin-off of $38.2 million, or $0.10 per diluted share, and



•

a loss on extinguishment of debt of $127.6 million, or $0.35 per diluted share.

            Core business fundamentals during the first nine months of 2014 improved compared to the first nine months of 2013, primarily driven by strong leasing activity. Our share of portfolio NOI grew by 8.8% for the nine month period in 2014 over the prior year period. Comparable property NOI also grew 5.4% for our portfolio of U.S. Malls, Premium Outlets, and The Mills. Total sales per square foot, or psf, remained relatively flat at $614 psf at September 30, 2013 compared to $613 psf at September 30, 2014 for the U.S. Malls and Premium Outlets. Total sales volume reported by all of our tenants, excluding anchors, increased 2.6% on a trailing twelve month basis. The increase in total sales in the third quarter of 2014,

excluding anchors, compared to the third quarter of 2013 was 2.8%. Average base minimum rent for U.S. Malls and Premium Outlets increased 4.4% to $46.29 psf as of September 30, 2014, from $44.33 psf as of September 30, 2013. 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 $9.67 psf ($65.46 openings compared to $55.79 closings) as of September 30, 2014, representing a 17.3% increase over expiring payments. Ending occupancy for the U.S. Malls and Premium Outlets was 96.9% as of September 30, 2014, as compared to 96.3% as of September 30, 2013, an increase of 60 basis points.

            Our effective overall borrowing rate at September 30, 2014 on our consolidated indebtedness decreased 49 basis points to 4.42% as compared to 4.91% at September 30, 2013. This decrease was primarily due to a decrease in the effective overall borrowing rate on fixed rate debt of 57 basis points (4.71% at September 30, 2014 as compared to 5.28% at September 30, 2013). At September 30, 2014, the weighted average years to maturity of our consolidated mortgage indebtedness was 4.0 years as compared to 5.4 years at December 31, 2013. Our financing activities for the nine months ended September 30, 2014, included:

•

Completing cash tender offers for any and all of five series of the Operating Partnership's outstanding senior unsecured notes with maturity dates ranging from 2015 to 2017. The total principal amount of the notes tendered and accepted for purchase was approximately $1.322 billion, with a weighted average duration of 1.7 years and a weighted average coupon rate of 5.60%. The Operating Partnership purchased the tendered notes using cash on hand and the proceeds from an offering of $1.3 billion of senior unsecured notes that closed on September 10, 2014. The senior notes offering was comprised of $900.0 million of 3.375% notes due 2024 and $400.0 million of 4.25% notes due 2044. Combined, the new issues of senior notes have a weighted average duration of 16.1 years and a weighted average coupon rate of 3.64%. Proceeds from the senior notes offering were also used to fund the redemption on September 30, 2014 of all $250.0 million outstanding principal amount of the 7.875% notes due 2016 issued by one of our subsidiaries. We recorded a $127.6 million loss on extinguishment of debt in the third quarter of 2014 as a result of the tender offers and redemption.



•

In addition to the tender offers and redemption described above, redeeming at par or repaying at maturity $934.5 million of senior unsecured notes with fixed rates ranging from 4.90% to 6.75%.



•

Issuing $600.0 million of senior unsecured notes at a fixed interest rate of 2.20% with a maturity date of February 1, 2019 and $600.0 million of senior unsecured notes at a fixed interest rate of 3.75% with a maturity date of February 1, 2024 on January 21, 2014.



•

Repaying $300.0 million on our $4.0 billion unsecured revolving credit facility, or Credit Facility.



•

Unencumbering two properties by repaying $1.1 billion in mortgage loans.

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 disposed properties in the year of disposition. The Washington Prime properties have been removed from the portfolio data for all periods presented. For comparative purposes, we separate the information related to 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, mall majors, mall freestanding and mall outlots 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 stores with less than 10,000 square feet) in the malls and The Mills and all reporting tenants in the Premium Outlets. 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 nine months ended September 30, 2014, we signed 626 new leases and 1,243 renewal leases (excluding mall anchors and majors, new development, redevelopment, expansion, downsizing and relocation) with a fixed minimum rent across our U.S. Malls and Premium Outlets portfolio, comprising approximately 5.9 million square feet of which 4.4 million square feet related to consolidated properties. During the comparable period in 2013, we signed 744 new leases and 1,082 renewal leases, comprising approximately 5.4 million square feet of which 4.0 million square feet related to consolidated properties. The average annual initial base minimum rent for new leases was $59.14 per square foot in 2014 and $49.86 per square foot in 2013 with an average tenant allowance on new leases of $37.35 per square foot and $33.35 per square foot, respectively.

            For the purposes of the following comparison between the three and nine months ended September 30, 2014 and 2013, 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 September 30, 2014 vs. Three months ended September 30, 2013

            Minimum rents increased $49.3 million during 2014, of which the property transactions accounted for $7.7 million of the increase. Comparable rents increased $41.6 million, or 6.3%, primarily attributable to an increase in base minimum rents.

            Tenant reimbursements increased $30.4 million, due to a $4.8 million increase attributable to the property transactions and a $25.6 million, or 8.5%, increase in the comparable properties primarily due to annual fixed contractual increases related to common area maintenance and additional marketing recoveries related to increased digital and social media advertising costs.

            Total other income increased $7.9 million, principally as a result of a $6.8 million increase in lease settlement activity.

            Advertising and promotion increased $9.9 million primarily related to higher digital and social media advertising costs.

            Home and regional office costs increased $6.6 million primarily related to higher personnel costs including incentive compensation.

            Interest expense decreased $20.9 million primarily due to the net impact of the financing activities and reduction in the effective overall borrowing rate as previously discussed.

            During the quarter ended September 30, 2014, we recorded a loss on extinguishment of debt of $127.6 million as a result of the tender offers and redemption.

            Income and other taxes decreased $1.1 million primarily due to a decrease in state income taxes.

            Income from unconsolidated entities increased $8.1 million primarily due to favorable results of operations from the development and redevelopment of joint venture properties and international investments.

            During the quarter ended September 30, 2014, we recorded a gain of $17.7 million related to our disposal of two retail properties. During the quarter ended September 30, 2013, we disposed of our interest in one mall, one community center and one retail property resulting in an aggregate gain of $11.1 million.

            Discontinued operations decreased $38.6 million due to three full months of ownership of the Washington Prime properties in 2013 and no ownership of those properties during the comparable period in 2014.

            Net income attributable to noncontrolling interests decreased $10.6 million due to a decrease in the net income of the Operating Partnership.

Nine months ended September 30, 2014 vs. Nine months ended September 30, 2013

            Minimum rents increased $152.5 million during 2014, of which the property transactions accounted for $28.1 million of the increase. Comparable rents increased $124.4 million, or 6.4%, primarily attributable to an increase in base minimum rents.

            Tenant reimbursements increased $97.2 million, due to a $12.7 million increase attributable to the property transactions and a $84.5 million, or 9.8%, increase in the comparable properties primarily due to utility reimbursements,

annual fixed contractual increases related to common area maintenance and additional marketing recoveries related to costs incurred during our property rebranding initiative and increased digital and social media advertising costs.

            Total other income increased $31.5 million, principally as a result of a $16.9 million increase in lease settlement income and an $8.8 million increase in land sale activity.

            Property operating expense increased $17.8 million due to a $5.5 million increase related to the property transactions, and a $12.2 million increase related to the comparable properties primarily as a result of increased utility expenses partially due to the harsh winter.

            Repairs and maintenance expense increased $4.1 million primarily due to increased snow removal costs compared to the prior year.

            Advertising and promotion increased $24.0 million primarily related to costs incurred during our property rebranding initiative and increased digital and social media advertising costs.

            Provision for credit losses increased $4.7 million as a result of increased reserves due to an increase in tenant bankruptcies and a decrease in recoveries as compared to 2013. The 2014 expense is in line with longer term historical levels.

            Home and regional office costs increased $15.0 million primarily related to higher personnel costs including incentive compensation and one-time items related to the spin-off of Washington Prime.

            Other expenses increased $3.4 million primarily due to increased legal and professional fees.

            Interest expense decreased $49.3 million primarily due to the net impact of the financing activities and reduction in the effective overall borrowing rate as previously discussed.

            During 2014, we recorded a loss on extinguishment of debt of $127.6 million as a result of the tender offers and redemption that occurred during the third quarter of 2014.

            Income and other taxes decreased $9.7 million primarily due to taxes related to certain of our international investments and a decrease in state income taxes.

            Income from unconsolidated entities increased $10.7 million primarily due to favorable results of operations from the development and redevelopment of joint venture properties and international investments.

            During the nine months ended September 30, 2014, we recorded a gain related to Klépierre's sale of a portfolio of 126 properties and our disposal of two retail properties. Additionally, we acquired the remaining 50% interest in Arizona Mills from our joint venture partner. The property was previously accounted for under the equity method and we recognized a non-cash gain upon consolidation of this property. The aggregate gain recognized on these transactions was $154.2 million. During the nine months ended September 30, 2013, we disposed of our interest in two community centers, two malls, two retail properties and recorded a gain on the acquisition of an outlet center. The aggregate gain recognized on these transactions was approximately $85.8 million.

            Discontinued operations decreased $68.3 million due to the 2014 period including approximately five months ownership of the Washington Prime properties, whereas the 2013 period included nine full months of ownership of those properties. The 2013 activity also includes a $14.2 million gain on the disposal of three strip centers held within a joint venture portfolio of Washington Prime properties. Additionally, on February 28, 2014 one strip center was sold by that same joint venture for a gain of $0.2 million. In 2014, we also incurred $38.2 million in transaction costs related to the Washington Prime spin-off.

            Net income attributable to noncontrolling interests increased $7.8 million due to an increase in the net income of the Operating Partnership.

Liquidity and Capital Resources

            Because we own long-lived income-producing assets, our financing strategy relies primarily on long-term fixed rate debt. Floating rate debt currently comprises only 8.0% of our total consolidated debt at September 30, 2014. We also enter into interest rate protection agreements to manage our interest rate risk. We derive most of our liquidity from positive net cash flow from operations and distributions of capital from unconsolidated entities that totaled $2.3 billion during the nine months ended September 30, 2014. In addition, the Credit Facility and the $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. Borrowing capacity under each of these facilities can be increased at our sole option as discussed further below.

            Our balance of cash and cash equivalents from continuing operations decreased $873.0 million during the first nine months of 2014 to $818.0 million as of September 30, 2014 as further discussed under "Cash Flows" below.

            On September 30, 2014, we had an aggregate available borrowing capacity of $5.2 billion under the two credit facilities, net of outstanding borrowings of $810.2 million and letters of credit of $39.0 million. For the nine months ended September 30, 2014, the maximum amount outstanding under the two credit facilities was $1.2 billion and the weighted average amount outstanding was $900.9 million. The weighted average interest rate was 1.02% for the nine months ended September 30, 2014.

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

            Our business model and status as a REIT 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 2014.

Cash Flows

            Our net cash flow from operating activities and distributions of capital from unconsolidated entities for the nine months ended September 30, 2014 totaled $2.3 billion. In addition, we had net repayments from our debt financing and repayment activities, including the $127.6 million debt extinguishment charge, of $1.6 billion in 2014 and net proceeds from debt financings related to the Washington Prime spin-off of $1.0 billion. These activities are further discussed below under "Financing and Debt." During the first nine months of 2014, we or the Operating Partnership also:

•

funded the acquisition of one of our partner's remaining redeemable interests in a portfolio of ten properties, acquired the remaining 50% ownership interest in Arizona Mills from our joint venture partner, contributed funds into a partnership in exchange for a new series of preferred partnership units, and acquired an undeveloped land parcel, the aggregate cash portion of which was $258.1 million,



•

paid stockholder dividends and unitholder distributions totaling $1.4 billion,



•

funded consolidated capital expenditures of $467.1 million (includes development and other costs of $21.7 million, redevelopment and expansion costs of $270.0 million, and tenant costs and other operational capital expenditures of $175.4 million), and



•

funded investments in unconsolidated entities of $155.8 million and received repayments of construction loans to joint ventures of $62.5 million, net of funding.

            In general, we anticipate that cash generated from operations will be sufficient to meet operating expenses, monthly debt service, recurring capital expenditures, and dividends to stockholders necessary to maintain our REIT qualification on a long-term basis. In addition, we expect to be able to generate or obtain capital for nonrecurring capital expenditures, such as acquisitions, major building redevelopments 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 and commercial paper program,



•

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 2014, 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. 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 September 30, 2014, our unsecured debt consisted of $13.8 billion of senior unsecured notes of the Operating Partnership, net of discounts, $606.6 million outstanding under the Credit Facility, $203.5 million outstanding under the Supplemental Facility, and $240.0 million outstanding under an unsecured term loan. At September 30, 2014, the Credit Facility had a capacity of $4.0 billion including a $2.0 billion multi-currency tranche, an initial maturity of June 30, 2018, an interest rate of LIBOR plus 80 basis points and an additional facility fee of 10 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 entire balance on the Credit Facility at September 30, 2014 consisted 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 September 30, 2014, we had an aggregate available borrowing capacity of $5.2 billion under the two credit facilities. The maximum outstanding balance of the credit facilities during the nine months ended September 30, 2014 was $1.2 billion and the weighted average outstanding balance was $900.9 million. Letters of credit of $39.0 million were outstanding under the two credit facilities as of September 30, 2014.

            On April 7, 2014, the Operating Partnership amended and extended the Credit Facility. The initial borrowing capacity of $4.0 billion may be increased to $5.0 billion during its term and provides for borrowings denominated in U.S. Dollars, Euros, Yen, Sterling, Canadian Dollars and Australian Dollars. Borrowings in currencies other than the U.S. Dollar are limited to 75% of the maximum revolving credit amount, as defined. The initial maturity date was extended to June 30, 2018 and can be extended for an additional year at our sole option to a final maturity date of June 30, 2019. The base interest rate on the amended Credit Facility was reduced to LIBOR plus 80 basis points and the additional facility fee was reduced to 10 basis points.

            The Supplemental Facility's borrowing capacity of $2.0 billion may be increased 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. As of September 30, 2014, the base interest rate on the Supplemental Facility was LIBOR plus 95 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.

            On September 3, 2014, the Operating Partnership commenced cash tender offers for any and all of five series of our outstanding senior unsecured notes with maturity dates ranging from 2015 to 2017. The total principal amount of notes tendered and accepted for purchase was approximately $1.322 billion, with a weighted average remaining duration of 1.7 years and a weighted average coupon rate of 5.60%. The Operating Partnership purchased the tendered notes using cash on hand and the proceeds from an offering of $1.3 billion of senior unsecured notes that closed on September 10, 2014. The senior notes offering was comprised of $900.0 million of 3.375% notes due 2024 and $400.0 million of 4.25% notes due 2044. Combined, the new issues of senior notes have a weighted average duration of 16.1 years and a weighted average coupon rate of 3.64%. Proceeds from the senior notes offering were also used to fund the redemption on September 30, 2014 of all $250.0 million outstanding principal amount of the 7.875% notes due 2016 issued by one of our subsidiaries. We recorded a $127.6 million loss on extinguishment of debt in the third quarter of 2014 as a result of the tender offers and redemption.

            On January 21, 2014, the Operating Partnership issued $600.0 million of senior unsecured notes at a fixed interest rate of 2.20% with a maturity date of February 1, 2019 and $600.0 million of senior unsecured notes at a fixed interest rate of 3.75% with a maturity date of February 1, 2024. Proceeds from the unsecured notes offering were used to repay debt and for general corporate purposes.

            In addition to the tender offers and redemption described above, during the nine months ended September 30, 2014, we used cash on hand to redeem at par or repay at maturity $934.5 million of senior unsecured notes with fixed rates ranging from 4.90% to 6.75%.

            On October 6, 2014, the Operating Partnership entered into a global unsecured commercial paper note program. Under the terms of this program, the Operating Partnership may issue unsecured commercial paper notes, denominated in U.S. dollars, Euros and other currencies, up to a maximum aggregate amount outstanding at any time of $500.0 million, or the non-U.S. equivalent thereof. Notes issued in non-U.S. currencies may be issued by one or more subsidiaries of the Operating Partnership and are guaranteed by the Operating Partnership. Notes will be sold under customary terms in the

U.S and Euro commercial paper note markets and will rank (either by themselves or as a result of the guarantee described above) pari passu with all of the Operating Partnership's other unsecured senior indebtedness.

Mortgage Debt

            Total mortgage indebtedness was $6.3 billion and $7.3 billion at September 30, 2014 and December 31, 2013, respectively.

            On January 2, 2014, we repaid the $820.0 million outstanding mortgage at Sawgrass Mills originally maturing July 1, 2014 and on February 28, 2014, we repaid the $269.0 million outstanding mortgage at Great Mall originally maturing August 28, 2015. During the third quarter of 2014, we disposed of our interests in two retail properties and their related mortgage debt of $48.4 million.

Covenants

            Our unsecured debt agreements contain financial and other 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 September 30, 2014, we were in compliance with all covenants of our unsecured debt.

            At September 30, 2014, we or our subsidiaries are the borrowers under 39 non-recourse mortgage notes secured by mortgages on 53 properties, including five separate pools of cross-defaulted and cross-collateralized mortgages encumbering a total of 21 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 instruments 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 September 30, 2014, the applicable borrowers under these non-recourse mortgage notes were in compliance with all covenants where non-compliance could individually, or giving effect to applicable cross-default provisions in the aggregate, 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 September 30, 2014 and December 31, 2013, consisted of the following (dollars in thousands):

Contractual Obligations

            There have been no material changes to our outstanding capital expenditure and lease commitments previously disclosed in our 2013 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 September 30, 2014, for the remainder of 2014 and subsequent years thereafter (dollars in thousands) assuming the obligations remain outstanding through initial maturities including applicable exercise of available extension options:

Off-Balance Sheet Arrangements

            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 September 30, 2014, the Operating Partnership guaranteed joint venture related mortgage indebtedness of $226.2 million (of which we have a right of recovery from our joint venture partners of $80.5 million). Mortgages guaranteed by us are secured by the property of the joint venture which could be sold in order to satisfy the outstanding obligation and which has an estimated fair value in excess of the guaranteed amount. 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 fundings are not typically required contractually or otherwise.

Acquisitions and Dispositions

            Buy-sell, marketing rights, and other exit mechanisms 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 and 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 our partner's interest. 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 September 16, 2014, we entered into a definitive agreement under which we will acquire Jersey Gardens in Elizabeth, New Jersey and University Park Village in Fort Worth, Texas, properties currently owned by Glimcher Realty Trust, or Glimcher, for an aggregate cash purchase price of $1.09 billion. This acquisition will close concurrently with, and is subject to, the closing of the acquisition of Glimcher by Washington Prime, which is expected to occur in the first quarter of 2015.

            On April 10, 2014, through our joint venture with McArthurGlen, we acquired an additional 22.5% noncontrolling interest in Ashford Designer Outlet, increasing our ownership interest in this property to 45%.

            On January 30, 2014, we acquired the remaining 50% interest in Arizona Mills from our joint venture partner, as well as approximately 39 acres of land in Oyster Bay, New York, for approximately $145.8 million, consisting of cash consideration and 555,150 units of the Operating Partnership. Arizona Mills is subject to a mortgage which was $166.9 million at the time of the acquisition. 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 $2.7 million in the first quarter of 2014. We now own 100% of this property.

            On January 10, 2014, we acquired one of our partner's redeemable interests in a portfolio of ten properties for approximately $114.4 million subject to a pre-existing contractual arrangement. The amount paid to acquire the interests in the seven properties which were previously consolidated was included in limited partners' preferred interest in the Operating Partnership and noncontrolling redeemable interests in properties at December 31, 2013.

            During the second quarter of 2013, we signed a definitive agreement with McArthurGlen, an owner, developer, and manager of designer outlets, to form one or more joint ventures to invest in certain of its existing designer outlets, development projects, and its property management and development companies. In conjunction with that agreement, we purchased a noncontrolling interest in the property management and development companies of McArthurGlen, and a noncontrolling interest in a development property located in Vancouver, British Columbia. On August 2, 2013 we acquired a noncontrolling interest in Ashford Designer Outlet in Kent, UK. On October 16, 2013 we completed the remaining transactions contemplated by our previously announced definitive agreement with McArthurGlen by acquiring noncontrolling interests in portions of four existing McArthurGlen Designer Outlets — Parndorf (Vienna, Austria), La Reggia (Naples, Italy), Noventa di Piave (Venice, Italy), and Roermond (Roermond, Netherlands). Our initial legal ownership interests in these entities ranged from 22.5% to 90%.

            On May 30, 2013 we acquired a 100% interest in a 390,000 square foot outlet center located near Portland, Oregon for cash consideration of $146.7 million.

            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.

            As discussed in Note 3 to the condensed notes to consolidated financial statements, on May 28, 2014, we completed the spin-off of our interests in 98 properties comprised of substantially all of our strip center business and our smaller enclosed malls to Washington Prime.

            During the third quarter of 2014, we disposed of our interests in two consolidated retail properties. The aggregate gain recognized on these transactions was approximately $17.7 million. Also, during the third quarter of 2014, we sold our investment in a hotel located at Coconut Point in Estero, Florida. Our share of the gain from this sale was $4.4 million, which is included in other income in the consolidated statements of operations and comprehensive income.

Development Activity

            New Domestic Development.    During the third quarter of 2014, construction began on the following Premium Outlets:

•

Gloucester Premium Outlets, a 375,000 square foot project located in Gloucester, New Jersey, which is scheduled to open in August of 2015. We own a 50% noncontrolling interest in this project. Our estimated share of the cost of this project is $61.0 million.



•

Tucson Premium Outlets, a 366,000 square foot project, which is scheduled to open in October of 2015. We own a 100% interest in this project. The estimated cost of this project is $95.0 million.



•

Tampa Premium Outlets, a 441,000 square foot project, which is scheduled to open in October of 2015. We own a 100% interest in this project. The estimated cost of this project is $129.0 million.

During the third quarter of 2014, the following Premium Outlets opened:

•

Charlotte Premium Outlets, a 399,000 square foot project located in Charlotte, North Carolina opened on July 31, 2014. We own a 50% noncontrolling interest in this project, which is a joint venture with Tanger Factory Outlet Centers, Inc. Our share of the cost of this project is approximately $46.0 million.



•

Twin Cities Premium Outlets, a 409,000 square foot project located in Eagan, Minnesota opened on August 14, 2014. We own a 35% noncontrolling interest in this project. Our share of the cost of this project is approximately $37.0 million.

            Domestic Expansions and Redevelopments.    We routinely incur costs related to construction for significant redevelopment and expansion projects at our properties. Redevelopment and expansion projects, including the addition of anchors and big box tenants, are underway at more than 25 properties in the U.S.

            Our share of the costs of all development and redevelopment projects currently under construction is approximately $2.2 billion. We expect to fund these capital projects with cash flows from operations. Our estimated stabilized return on invested capital typically ranges between 8-12% for all of our new development, expansion and redevelopment 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. 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 2014 will be approximately $170 million, primarily funded through reinvested joint venture cash flow and construction loans.

            The following table describes these new development and expansion projects as well as our share of the estimated total cost as of September 30, 2014 (in millions):

Dividends

            We paid a common stock dividend of $1.30 per share in the third quarter of 2014. Our Board of Directors declared a cash dividend for the fourth quarter of 2014 of $1.30 per share of common stock payable on November 28, 2014 to stockholders of record on November 14, 2014. 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 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, security breaches that would compromise our information technology or infrastructure or personally identifiable data of customers of our retail properties, 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, risks related to international activities, insurance costs and coverage, loss of key management personnel, 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 subsequent 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 performance measures such as FFO, diluted FFO per share, NOI and comparable property NOI. We believe that these non-GAAP measures are helpful to investors

38

Table of Contents

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 or disposals 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 retail 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.

            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.

Item 3.    Quantitative and Qualitative Disclosures About Market Risk

            Sensitivity Analysis.    We disclosed a quantitative and qualitative analysis regarding market risk in the Management's Discussion and Analysis of Financial Condition and Results of Operations included in our 2013 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, 2013.

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.

            Simon's 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 September 30, 2014 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
