Simon Property Group, Inc. and Subsidiaries
Condensed Notes to Consolidated Financial Statements
(Unaudited)
(Dollars in thousands, except share and per share amounts
and where indicated in millions or billions)

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 June 30, 2015, we owned or held an interest in 207 income-producing properties in the United States, which consisted of 110 malls, 68 Premium Outlets, 14 Mills, three community centers, and 12 other retail properties in 37 states and Puerto Rico. Internationally, as of June 30, 2015, we had ownership interests in nine Premium Outlets in Japan, three Premium Outlets in South Korea, two Premium Outlets in Canada, one Premium Outlet in Mexico, and one Premium Outlet in Malaysia. As of June 30, 2015, we had a noncontrolling ownership interest in a joint venture that holds five outlet properties in Europe. 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 June 30, 2015, as further discussed in Note 5, we owned a 20.3% 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 16 countries in Europe.

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 June 30, 2015, 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 2014 Annual Report on Form 10-K.

As of June 30, 2015, we consolidated 135 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 80 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 80 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, Mexico, Malaysia, and the five European outlet properties comprise 19 of the remaining 22 properties. These 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 85.6% and 85.5% for the six months ended June 30, 2015 and 2014, respectively. As of June 30, 2015 and December 31, 2014, our ownership interest in the Operating Partnership was 85.7% and 85.5%, respectively. We adjust the noncontrolling limited partners' interests at the end of each period to reflect their interest in the net assets of the Operating Partnership.

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 of high credit quality. However, at certain times, such cash and cash equivalents are in excess of FDIC and SIPC insurance limits.

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 June 30, 2015, we had marketable securities of $184.2 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). Net unrealized gains recorded in accumulated other comprehensive income (loss) as of June 30, 2015 and December 31, 2014 were approximately $1.7 million and $103.9 million, respectively, and represent the valuation 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.

On June 24, 2015 we sold our investment in certain marketable securities that were accounted for as an available-for-sale security, with the value adjusted to its quoted market price through other comprehensive income (loss). At the date of sale, we owned 5.71 million shares. The aggregate proceeds received from the sale were $454.0 million, and we recognized a gain on the sale of $80.2 million, which is included in other income in the accompanying consolidated statements of operations and comprehensive income for the three and six months ended June 30, 2015.

At June 30, 2015 and December 31, 2014, we had investments of $177.3 million and $167.1 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.

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 June 30, 2015 and December 31, 2014 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 $0.7 million and $2.1 million at June 30, 2015 and December 31, 2014, respectively, and a gross asset value of $24.5 million and $20.1 million at June 30, 2015 and December 31, 2014, respectively.

Note 6 includes a discussion of the fair value of debt measured using Level 2 inputs. Notes 9 and 5 include a discussion of the fair values recorded in purchase accounting using Level 2 and Level 3 inputs. Level 3 inputs to our purchase accounting and impairment analyses include our estimations of net operating results of the property, capitalization rates and discount rates.

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.

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 both June 30, 2015 and December 31, 2014, we had the following outstanding interest rate derivatives related to managing our interest rate risk:

The carrying value of our interest rate swap agreements, at fair value, as of June 30, 2015, was a net asset balance of $0.9 million, of which $1.6 million is included in deferred costs and other assets and $0.6 million is included in other liabilities. The carrying value of our interest rate swap agreements, at fair value, as of December 31, 2014, was a net liability balance of $1.2 million, of which $2.1 million was included in other liabilities and $0.9 million was included in deferred costs and other assets.

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.

As of June 30, 2015, we had no outstanding Yen:USD forward contracts. Approximately ¥14.7 million remained at December 31, 2014 for our Yen forward contracts that matured on January 5, 2015. The December 31, 2014 asset balance related to these forward contracts was $0.1 million and was 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. During the second quarter, one forward contract with a €50.0 million notional value was settled. The June 30, 2015 asset balance related to the remaining €100.0 million forward contracts was $22.9 million and is included in deferred costs and other assets. The December 31, 2014 asset balance related to these forward contracts was $19.1 million and was included in deferred costs and other assets. 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 $21.2 million and $45.8 million as of June 30, 2015 and December 31, 2014, respectively.

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 became effective prospectively for fiscal years beginning after December 15, 2014, but could be early-adopted. We early-adopted ASU 2014-08 in the first quarter of 2014 and are applying the revised definition to all disposals on a prospective basis, including the spin-off of WP Glimcher Inc. (formerly known as Washington Prime Group Inc.), or 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. In July 2015, the FASB decided to delay the effective date of the new revenue recognition standard by one year, which will result in the new standard being effective for us beginning with the first quarter 2018. The new standard can be adopted either retrospectively to each prior reporting period presented or as a cumulative effect adjustment as of the date of adoption. We are currently evaluating the impact adopting the new accounting standard will have on our consolidated financial statements.

In February 2015, the FASB issued ASU 2015-02, "Amendments to the Consolidation Analysis." ASU 2015-02 makes changes to both the variable interest model and the voting model. This guidance becomes effective for annual and interim periods beginning after December 15, 2015. All reporting entities involved with limited partnerships will have to re-evaluate whether these entities qualify for consolidation and revise documentation accordingly. We are currently evaluating the impact adopting the new accounting standard will have on our consolidated financial statements.

In April 2015, the FASB issued ASU 2015-03, "Simplifying the Presentation of Debt Issuance Costs," ("ASU 2015-03"). ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 will be effective for us retrospectively beginning in the first quarter of 2016. We expect this new guidance will reduce total assets and total mortgage and unsecured indebtedness on our Consolidated Balance Sheet for amounts classified as deferred costs specific to debt issuance costs. We do not expect this guidance to have any other effect on our 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, 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 completed unsecured debt and mortgage debt as part of the spin-off and incurred $38.2 million in transaction costs during the first six months of 2014 related to the spin-off of Washington Prime.

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. 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.

Summarized financial information for discontinued operations for the three and six month periods ended June 30, 2014 is presented below.

Capital expenditures on a cash basis for the three and six month periods ended June 30, 2014 were $7.1 million and $31.9 million, respectively.

We and Washington Prime entered into property management and transitional services agreements in connection with the spin-off whereby we provide certain services to Washington Prime and its properties that were previously owned by us. Pursuant to the terms of the property management agreements, we manage, lease, and maintain those Washington Prime 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 that were previously owned by us 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. Transitional services fees earned for the three and six months ended June 30, 2015 were approximately $1.6 million and $2.9 million, respectively.

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 six months ended June 30, 2015, 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 three and six months ended June 30, 2015 and 2014. We accrue dividends when they are declared.

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 80 properties as of June 30, 2015.

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 June 30, 2015 and December 31, 2014, we had construction loans and other advances to related parties totaling $14.6 million and $14.9 million, respectively, which are included in deferred costs and other assets in the accompanying consolidated balance sheets.

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.

On February 24, 2015, Houston Galleria, in which we own a 50.4% noncontrolling interest, refinanced its $821.0 million mortgage with a $1.2 billion mortgage that matures on March 1, 2025. The fixed interest rate was reduced from 5.44% to 3.55% as a result. Excess proceeds from the financing were distributed to the venture partners in February 2015.

On April 13, 2015, we announced we had formed a joint venture with Sears Holdings, or Sears, whereby Sears contributed 10 of its properties located at our malls to the newly formed joint venture in exchange for a 50% noncontrolling interest in this joint venture. We contributed $114.0 million in cash in exchange for a 50% noncontrolling interest in this joint venture. Sears or its affiliates are leasing back each of the 10 properties from the joint venture. The joint venture has the right to recapture not less than 50% of the space leased to Sears to be used for purposes of redeveloping and releasing the recaptured space. We will provide development, leasing and management services to the joint venture. On July 7, 2015, we separately invested approximately $33.0 million in exchange for 1,125,760 common shares of Seritage Growth Properties, a public REIT recently formed by Sears, which now holds their previous interest in the newly formed joint venture.

On April 23, 2015, we announced a partnership with Swire Properties Inc. and Whitman Family Development to jointly develop the approximately 500,000 square foot shopping center component of Brickell City Centre, a mixed-use development in downtown Miami. We own a 25% interest in the retail component of this project which is scheduled to open in September 2016. Our share of the estimated cost of this project including development fees is approximately $100.0 million.

On July 22, 2015, we closed on our previously announced joint venture with Hudson's Bay Company, or HBC, whereby HBC contributed 42 properties and we committed to contribute $100.0 million for improvements to the properties contributed by HBC in exchange for a noncontrolling interest in the newly formed joint venture. We may contribute up to an additional $178.5 million in the newly formed joint venture. Upon the closing of the joint venture, we funded $1.0 million of our commitment. On June 15, 2015 HBC announced it is acquiring Galeria Holding, the parent company of Germany's leading department store, Kaufhof. This joint venture has agreed to purchase at least 40 Kaufhof properties from HBC. This transaction is expected to close in 2015.

At June 30, 2015, we owned 63,924,148 shares, or approximately 20.3%, of Klépierre, which had a quoted market price of $44.29 per share. 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 received 1.14 Klépierre ordinary shares for each Corio ordinary share. On January 15, 2015 the tender offer transaction closed and the merger was completed on March 31, 2015, reducing our ownership from 28.9% at December 31, 2014 to 18.3%. On May 11, 2015 we purchased 6,290,000 additional shares of Klépierre for $279.4 million bringing our ownership to 20.3%. All of the excess investment related to the purchase has been

allocated to investment property. Our share of net income, net of amortization of our excess investment, was $9.6 million and $135.9 million for the six months ended June 30, 2015 and 2014, respectively. 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 $740.3 million, $277.6 million and $96.9 million, respectively, for the six months ended June 30, 2015 and $654.8 million, $281.1 million and $1.2 billion, respectively, for the six months ended June 30, 2014. 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.

Our joint venture in Europe has interests in five outlet properties, one development project as well as a property management and development company. As of June 30, 2015 our legal percentage ownership interests in these entities range from 45% to 90%. 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 $605.8 million and $677.1 million as of June 30, 2015 and December 31, 2014, respectively. In December 2014, Roermond Designer Outlet phases 2 and 3, in which we own a 90% interest, refinanced its $85.1 million mortgage maturing in 2017 with a $218.9 million mortgage that matures in 2021. The fixed interest rate was reduced from 5.12% to 1.86% as a result. Excess proceeds from the financing were distributed to the venture partners in January 2015.

We also have a minority interests in Value Retail PLC and affiliated entities, which own or have interests in and operate nine luxury outlets throughout Europe and a direct minority ownership in three of those outlets. Our investment in these centers is accounted for under the cost method. At each of June 30, 2015 and December 31, 2014, the carrying value of these non-marketable investments was $115.4 million and is included in deferred costs and other assets.

On March 19, 2015 we disposed of our interest in a joint venture which had held interests in rights to pre-development projects in Europe, for total proceeds of $19.0 million. We recognized a gain on the sale of $8.3 million, which is included in other income in the accompanying consolidated statements of operations and comprehensive income. The gain includes $0.8 million that was reclassified from accumulated other comprehensive income (loss).

We conduct our international Premium Outlet operations in Japan through a joint venture with Mitsubishi Estate Co., Ltd. We have a 40% ownership interest in this joint venture. The carrying amount of our investment in this joint venture was $229.8 million as of June 30, 2015 and December 31, 2014, including all related components of accumulated other comprehensive income (loss). We conduct our international Premium Outlet operations in South Korea through a joint venture with Shinsegae International Co. We have a 50% ownership interest in this joint venture. The carrying amount of our investment in this joint venture was $110.4 million and $104.5 million as of June 30, 2015 and December 31, 2014, respectively, including all related components of accumulated other comprehensive income (loss).

A summary of our equity method investments and share of income from such investments, excluding Klépierre, follows. As discussed in Note 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 in the accompanying summary financial information for the six months ended June 30, 2014.

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

Our share of income from unconsolidated entities in the above table, aggregated with our share of the results of Klépierre, is presented in income from unconsolidated entities in the accompanying consolidated statements of operations and comprehensive income.

At June 30, 2015, our unsecured debt consisted of $13.0 billion of senior unsecured notes of the Operating Partnership, net of discounts, $1.4 billion outstanding under the Operating Partnership's $4.0 billion unsecured revolving credit facility, or Credit Facility, $240.0 million outstanding under an unsecured term loan, and $803.0 million outstanding under the Operating Partnership's global unsecured commercial paper note program, or the Commercial Paper program. The June 30, 2015 balance on the Credit Facility included $1.0 billion (U.S. dollar equivalent) of Euro-denominated borrowings and $181.5 million (U.S. dollar equivalent) of Yen-denominated borrowings. At June 30, 2015 the outstanding amount under the Commercial Paper program was $803.0 million, of which $193.0 million was related to U.S. dollar equivalent of Euro-denominated notes. Foreign currency denominated borrowings under both the Credit Facility and Commercial Paper program are designated as net investment hedges of a portion of our international investments.

On June 30, 2015, we had an aggregate available borrowing capacity of $4.5 billion under the Credit Facility and the Operating Partnership's $2.75 billion supplemental unsecured revolving credit facility, or Supplemental Facility. The maximum aggregate outstanding balance under the two credit facilities during the six months ended June 30, 2015 was $1.8 billion and the weighted average outstanding balance was $1.2 billion. Letters of credit of $37.2 million were outstanding under the two credit facilities as of June 30, 2015.

The Credit Facility's 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 of the Credit Facility is June 30, 2018 and can be extended for an additional year to June 30, 2019 at our sole option. The base interest rate on the Credit Facility is LIBOR plus 80 basis points with an additional facility fee of 10 basis points.

On March 2, 2015, the Operating Partnership amended and extended the Supplemental Facility. The initial borrowing capacity of $2.0 billion has been increased to $2.75 billion, may be further increased to $3.5 billion during its term, will initially mature on June 30, 2019 and can be extended for an additional year to June 30, 2020 at our sole option. The base interest rate on the amended Supplemental Facility was reduced to LIBOR plus 80 basis points and the additional facility fee was reduced to 10 basis points. The Supplemental Facility provides for borrowings denominated in U.S. Dollars, Euro, Yen, Sterling, Canadian Dollars and Australian Dollars.

On March 2, 2015, the Operating Partnership increased the maximum aggregate program size of its Commercial Paper program from $500.0 million to $1.0 billion, or the non-U.S. dollar equivalent thereof. The Operating Partnership may issue unsecured commercial paper notes, denominated in U.S. dollars, Euros and other currencies. 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 the Operating Partnership's other unsecured senior indebtedness. Our Commercial Paper program is supported by our Credit Facility and Supplemental Facility and if necessary or appropriate, we may make one or more draws under either the Credit Facility or Supplemental Facility to pay amounts outstanding from time to time on the Commercial Paper program. At June 30, 2015, we had $803.0 million outstanding under the Commercial Paper program, comprised of $610.0 million outstanding in U.S. dollar denominated notes and $193.0 million (U.S. dollar equivalent) of Euro denominated notes with weighted average interest rates of 0.22% and 0.05%, respectively. The borrowings mature on various dates from July 1, 2015 to September 25, 2015.

During the six months ended June 30, 2015, we used cash on hand to repay at maturity $326.8 million of senior unsecured notes with a fixed rate of 5.10%.

Total mortgage indebtedness was $6.6 billion and $6.2 billion at June 30, 2015 and December 31, 2014, respectively.

On January 15, 2015, as discussed in Note 9, we acquired two properties — Jersey Gardens in Elizabeth, New Jersey (renamed "The Mills at Jersey Gardens") and University Park Village in Fort Worth, Texas, subject to existing fixed-rate mortgage loans of $350.0 million and $55.0 million, respectively. The loans mature on November 1, 2020 and May 1, 2028 and bear interest at 3.83% and 3.85%, respectively.

Our unsecured debt agreements contain financial and other non-financial covenants. If we were to fail to comply with these covenants, after the expiration of the applicable cure periods, the debt maturity could be accelerated or other remedies could be sought by the lender including adjustments to the applicable interest rate. As of June 30, 2015, we were in compliance with all covenants of our unsecured debt.

At June 30, 2015, we or our subsidiaries are the borrowers under 40 non-recourse mortgage notes secured by mortgages on 54 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 June 30, 2015, 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.

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 $19.0 billion as of June 30, 2015 and December 31, 2014. The fair values of these financial instruments and the related discount rate assumptions as of June 30, 2015 and December 31, 2014 are summarized as follows:

During the six months ended June 30, 2015, we issued 486,702 shares of common stock to eight limited partners of the Operating Partnership in exchange for an equal number of units pursuant to the partnership agreement of the Operating Partnership.

On April 2, 2015, our Board of Directors authorized us to repurchase up to $2.0 billion of our common stock over the next twenty-four months as market conditions warrant. We may repurchase the shares in the open market or in privately negotiated transactions. During the second quarter of 2015, we repurchased 1,903,340 shares at an average price of $180.19 per share as part of this program.

On May 14, 2015, the Operating Partnership redeemed 944,359 units from a limited partner for $162.7 million.

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, as amended, 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 2015, 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:

LTIP Program	LTIP Units Earned	Grant Date Fair Value

2010 LTIP Program
1-year 2010 LTIP Program	133,673	1-year program — $7.2 million
2-year 2010 LTIP Program	337,006	2-year program — $14.8 million
3-year 2010 LTIP Program	489,654	3-year program — $23.0 million
2011-2013 LTIP Program	469,848	$35.0 million
2012-2014 LTIP Program	401,203	$35.0 million
2013-2015 LTIP Program	To be determined in 2016	$29.5 million
2014-2016 LTIP Program	To be determined in 2017	$30.0 million
2015-2017 LTIP Program	To be determined in 2018	$29.9 million

We recorded compensation expense, net of capitalization, related to these LTIP programs of approximately $12.4 million and $13.6 million for the six months ended June 30, 2015 and 2014, respectively.

The Compensation Committee awarded 1,989 and 58,083 shares of restricted stock to employees on February 26, 2015 and April 1, 2015, respectively, under the Plan, at a fair market value of $187.14 per share and $197.99 per share, respectively. On May 14, 2015, our non-employee Directors were awarded an aggregate of 3,323 shares of restricted stock under the Plan at a fair market value of $184.76 per share. The grant date fair value of the employee restricted stock awards is being recognized as expense over the three-year vesting service period. The grant date fair value of the Director restricted stock awards is being recognized as expense over the one-year vesting service period.

We recorded compensation expense, net of capitalization, related to restricted stock of approximately $4.2 million and $7.4 million for the six months ended June 30, 2015 and 2014, respectively.

Other Compensation Arrangements. On July 6, 2011, in connection with the execution of an eight year employment agreement, the Compensation Committee granted David Simon, our Chairman and CEO, a retention award in the form of 1,000,000 LTIP units, or the Award, for his continued service as our Chairman and Chief Executive Officer through July 5, 2019. Effective December 31, 2013, the Award was modified, or the 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 our 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, or FFO, per share. If the performance criteria have been met, a maximum of 360,000 LTIP units, or the A Units, 360,000 LTIP units, or the B Units, and 280,000 LTIP units, or the 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 through the applicable vesting periods of the A Units, B Units and C Units.

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 and remediation work has been completed. The property was re-opened March 29, 2012. The excess insurance carriers (those providing coverage above $50 million) denied the claim under the policy for additional proceeds (of up to $150 million) to pay further amounts for restoration costs and business interruption losses. In the first quarter of 2015, summary judgment was granted in our favor, concluding that up to $150 million of additional coverage is available under our excess insurance policy for this claim. In July 2015, trial on the damages portion of our claim began. We and our lenders are continuing our efforts through pending litigation to recover our losses, including consequential damages, 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.

Joint venture debt is the liability of the joint venture and is typically secured by the joint venture property, which is non-recourse to us. As of June 30, 2015 and December 31, 2014, the Operating Partnership guaranteed joint venture related mortgage indebtedness of $319.9 million and $223.5 million, respectively (of which we have a right of recovery from our joint venture partners of $96.7 million and $78.7 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.

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.

During the second quarter of 2015, we disposed of our interests in two unconsolidated retail properties. The aggregate gain recognized on these transactions was approximately $16.3 million.

On January 15, 2015, we acquired a 100% interest in Jersey Gardens (renamed The Mills at Jersey Gardens) in Elizabeth, New Jersey and University Park Village in Fort Worth, Texas, properties previously owned by Glimcher Realty Trust for $677.9 million of cash and the assumption of existing mortgage debt of $405.0 million. We recorded the assets and liabilities of these properties at estimated fair value at the acquisition date, the majority of which was allocated to the investment property. The purchase price allocation is preliminary and subject to revision within the measurement period, not to exceed one year from the date of acquisition.

On April 10, 2014, through a European joint venture, we acquired an additional 22.5% noncontrolling interest in Ashford Designer Outlet, increasing our percentage ownership 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 interests in a portfolio of ten properties for approximately $114.4 million, seven of which were previously consolidated.

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. We expense acquisition, potential acquisition and disposition related costs as they are incurred. We incurred $4.4 million in transaction costs during the first six months of 2015 in connection with the acquisitions of Jersey Gardens and University Park Village, which are included in other expenses in the accompanying consolidated statements of operations and comprehensive income. We also 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 six months ended June 30, 2015 and 2014.

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.

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 June 30, 2015, we owned or held an interest in 207 income-producing properties in the United States, which consisted of 110 malls, 68 Premium Outlets, 14 Mills, three community centers, and 12 other retail properties in 37 states and Puerto Rico. We have four Premium Outlets and two malls under development and have redevelopment and expansion projects, including the addition of anchors, big box tenants, and restaurants, underway at 28 properties. Internationally, as of June 30, 2015, we had ownership interests in nine Premium Outlets in Japan, three Premium Outlets in South Korea, two Premium Outlets in Canada, one Premium Outlet in Mexico, and one Premium Outlet in Malaysia. As of June 30, 2015, we had a noncontrolling ownership interest in a joint venture that holds five outlet properties in Europe. 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 June 30, 2015, we owned a 20.3% 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 16 countries in Europe.

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

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:

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.

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.

Diluted earnings per common share increased $0.28 during the first six months of 2015 to $2.69 from $2.41 for the same period last year. The increase in diluted earnings per share was primarily attributable to:

Core business fundamentals during the first six months of 2015 improved compared to the first six months of 2014, primarily driven by higher tenant sales and strong leasing activity. Our share of portfolio NOI grew by 7.9% for the six month period in 2015 over the prior year period. Comparable property NOI also grew 3.5% for our portfolio of U.S. Malls, Premium Outlets, and The Mills. Total sales per square foot, or psf, increased 2.0% from $608 psf at June 30, 2014 to $620 psf at June 30, 2015, for our U.S. Malls and Premium Outlets. Average base minimum rent for U.S. Malls and Premium Outlets increased 4.9% to $48.07 psf as of June 30, 2015, from $45.83 psf as of June 30, 2014. Releasing spreads remained positive in our 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 $10.87 psf ($69.90 openings compared to $59.03 closings) as of June 30, 2015, representing an 18.4% increase over expiring payments. Ending occupancy for our U.S. Malls and Premium Outlets was 96.1% as of June 30, 2015, as compared to 96.5% as of June 30, 2014, a decrease of 40 basis points primarily as a result of tenant bankruptcy activity announced in the first quarter of 2015.

Our effective overall borrowing rate at June 30, 2015 on our consolidated indebtedness decreased 41 basis points to 4.17% as compared to 4.58% at June 30, 2014. This reduction was primarily due to a decrease in the effective overall borrowing rate on fixed rate debt of 18 basis points (4.70% at June 30, 2015 as compared to 4.88% at June 30, 2014) combined with a decrease in the effective overall borrowing rate on variable rate debt of 13 basis points (0.95% at June 30, 2015 as compared to 1.08% at June 30, 2014). At June 30, 2015, the weighted average years to maturity of our

consolidated indebtedness was 5.6 years as compared to 6.2 years at December 31, 2014. Our financing activities for the six months ended June 30, 2015, included:

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.

*Total Sales per Square Foot*	$571	$529	7.9%

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.

During the six months ended June 30, 2015, we signed 418 new leases and 702 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 3.4 million square feet of which 2.6 million square feet related to consolidated properties. During the comparable period in 2014, we signed 402 new leases and 939 renewal leases with a fixed minimum rent, comprising approximately 4.2 million square feet of which 3.0 million square feet related to consolidated properties. The average annual initial base minimum rent for new leases was $53.44 per square foot in 2015 and $56.14 per square foot in 2014 with an average tenant allowance on new leases of $41.66 per square foot and $36.79 per square foot, respectively.

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

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

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

For the purposes of the following comparison between the three and six months ended June 30, 2015 and 2014, 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.

Minimum rents increased $39.7 million during 2015, of which the property transactions accounted for $10.4 million of the increase. Comparable rents increased $29.3 million, or 4.2%, primarily attributable to an increase in base minimum rents.

Tenant reimbursements increased $22.1 million, due to a $6.0 million increase attributable to the property transactions and a $16.1 million, or 5.0%, increase in the comparable properties primarily due to annual fixed contractual increases related to common area maintenance and real estate tax recoveries.

Total other income increased $101.7 million, principally as a result of the following:

Property operating expense increased $7.2 million, due to a $2.7 million increase related to the property transactions, and a $4.5 million increase in comparable property activity as a result of inflationary cost increases.

Real estate taxes increased $7.1 million, of which the property transactions accounted for $1.9 million, with the remaining increase primarily caused by higher tax estimates in 2015.

Home and regional office costs decreased $5.6 million primarily related to higher personnel costs, including one-time items related to the spin-off of Washington Prime during 2014.

Other expenses increased $4.9 million primarily due to an increase in legal costs and professional fees, partially offset by a favorable net foreign currency revaluation impact on foreign currency denominated assets and liabilities.

Interest expense decreased $24.0 million primarily due to the net impact of our financing activities during 2014 and 2015 and the reduction in our effective overall borrowing rate as previously discussed.

Income and other taxes decreased $3.2 million primarily due to taxes related to certain of our international investments and a decrease in state income taxes.

Income from unconsolidated entities increased $14.4 million primarily due to favorable results of operations and financing activity of joint venture properties.

During the second quarter of 2015, we disposed of our interests in two unconsolidated retail properties resulting in a gain of $16.3 million. During the quarter ended June 30, 2014, we recorded a gain of $133.9 million related to Klépierre's sale of a portfolio of 126 properties.

Discontinued operations increased $12.1 million due to the second quarter of 2014 including approximately two months of our ownership of the Washington Prime properties, whereas 2015 did not include any ownership of those properties. Results for 2014 include $38.2 million in transaction costs related to the Washington Prime spin-off.

Net income attributable to noncontrolling interests increased $10.7 million due to an increase in the net income of the Operating Partnership.

Minimum rents increased $70.8 million during 2015, of which the property transactions accounted for $21.6 million of the increase. Comparable rents increased $49.2 million, or 3.5%, primarily attributable to an increase in base minimum rents.

Tenant reimbursements increased $36.8 million, due to a $12.9 million increase attributable to the property transactions and a $23.9 million, or 3.8%, increase in the comparable properties primarily due to annual fixed contractual increases related to common area maintenance and real estate tax recoveries.

Total other income increased $103.3 million, principally as a result of the following:

Property operating expense increased $12.0 million, due to a $5.3 million increase related to the property transactions, and a $6.7 million increase in comparable property activity as a result of inflationary cost increases.

Real estate taxes increased $19.7 million, of which the property transactions accounted for $5.2 million, with the remaining increase primarily caused by higher tax estimates in 2015.

Home and regional office costs decreased $5.0 million primarily related to higher personnel costs, including one-time items related to the spin-off of Washington Prime during 2014.

Other expenses increased $4.7 million primarily due to an increase in legal costs and professional fees and costs associated with our first quarter acquisition activity in 2015, partially offset by a favorable net foreign currency revaluation impact on foreign currency denominated assets and liabilities.

Interest expense decreased $46.0 million primarily due to the net impact of our financing activities during 2014 and 2015 and the reduction in our effective overall borrowing rate as previously discussed.

Income and other taxes decreased $3.7 million primarily due to taxes related to certain of our international investments.

Income from unconsolidated entities increased $22.2 million primarily due to favorable results of operations and financing activity of joint venture properties.

During the six months ended June 30, 2015, we disposed of our interests in two unconsolidated retail properties resulting in a gain of $16.3 million. During the six months ended June 30, 2014, we recorded a $133.9 million gain related to Klépierre's sale of a portfolio of 126 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 of $2.7 million. The aggregate gain recognized on these transactions was $136.5 million.

Discontinued operations decreased $29.3 million due to the first six months of 2014 including approximately five months of our ownership of the Washington Prime properties, whereas 2015 did not include any ownership of those properties. Results for 2014 include $38.2 million in transaction costs related to the Washington Prime spin-off.

Net income attributable to noncontrolling interests increased $14.6 million due to an increase in the net income of the Operating Partnership.

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 14.0% of our total consolidated debt at June 30, 2015. 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 $2.1 billion during the six months ended June 30, 2015. In addition, the Credit Facility, Supplemental Facility, and the Commercial Paper program provide alternative sources of liquidity as our cash needs vary from time to time. Borrowing capacity under these credit facilities may be increased as discussed further below.

Our balance of cash and cash equivalents decreased $46.6 million during the first six months of 2015 to $565.7 million as of June 30, 2015 as further discussed in "Cash Flows" below.

On June 30, 2015, we had an aggregate available borrowing capacity of $4.5 billion under the Credit Facility and Supplemental Facility, net of outstanding borrowings of $1.4 billion and letters of credit of $37.2 million. For the six months ended June 30, 2015, the maximum aggregate amount outstanding under the two credit facilities was $1.8 billion and the weighted average amount outstanding was $1.2 billion. The weighted average interest rate was 0.81% for the six months ended June 30, 2015. Further, on October 6, 2014, the Operating Partnership entered into the global Commercial Paper program and on March 2, 2015, increased the maximum aggregate program size from $500.0 million to $1.0 billion as further discussed below.

We and the Operating Partnership have historically had access to public equity and long and short-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, the Supplemental Facility, and the Commercial Paper program to address our debt maturities and capital needs through 2015.

Our net cash flow from operating activities and distributions of capital from unconsolidated entities for the six months ended June 30, 2015 totaled $2.1 billion. In addition, we had net proceeds from our debt financing and repayment activities of $891.6 million in 2015. These activities are further discussed below under "Financing and Debt." During the first six months of 2015, we or the Operating Partnership also:

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:

We expect to generate positive cash flow from operations in 2015, 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.

At June 30, 2015, our unsecured debt consisted of $13.0 billion of senior unsecured notes of the Operating Partnership, net of discounts, $1.4 billion outstanding under the Credit Facility, $240.0 million outstanding under an unsecured term loan, and $803.0 million outstanding under the Commercial Paper program. The June 30, 2015 balance on the Credit Facility included $1.0 billion (U.S. dollar equivalent) of Euro-denominated borrowings and $181.5 million (U.S. dollar equivalent) of Yen-denominated borrowings. At June 30, 2015 the outstanding amount under the Commercial Paper program was $803.0 million, of which $193.0 million was related to U.S. dollar equivalent of Euro-denominated notes. Foreign currency denominated borrowings under both the Credit Facility and Commercial Paper program are designated as net investment hedges of a portion of our international investments.

On June 30, 2015, we had an aggregate available borrowing capacity of $4.5 billion under the Credit Facility and the Supplemental Facility. The maximum aggregate outstanding balance of the credit facilities during the six months ended June 30, 2015 was $1.8 billion and the weighted average outstanding balance was $1.2 billion. Letters of credit of $37.2 million were outstanding under the two credit facilities as of June 30, 2015.

During the six months ended June 30, 2015, we used cash on hand to repay at maturity $326.8 million of senior unsecured notes with a fixed rate of 5.10%.

Total mortgage indebtedness was $6.6 billion and $6.2 billion at June 30, 2015 and December 31, 2014, respectively.

On January 15, 2015 we acquired two properties — Jersey Gardens in Elizabeth, New Jersey (renamed "The Mills at Jersey Gardens") and University Park Village in Fort Worth, Texas, subject to existing fixed-rate mortgage loans of $350.0 million and $55.0 million, respectively. The loans mature on November 1, 2020 and May 1, 2028 and bear interest at 3.83% and 3.85%, respectively.

Our consolidated debt, adjusted to reflect outstanding derivative instruments, and the effective weighted average interest rates as of June 30, 2015 and December 31, 2014, consisted of the following (dollars in thousands):

There have been no material changes to our outstanding capital expenditure and lease commitments previously disclosed in our 2014 Annual Report on Form 10-K.

In regards to long-term debt arrangements, the following table summarizes the material aspects of these future obligations on our consolidated indebtedness as of June 30, 2015, for the remainder of 2015 and subsequent years thereafter (dollars in thousands) assuming the obligations remain outstanding through initial maturities including applicable exercise of available extension options:

Our off-balance sheet arrangements consist primarily of our investments in joint ventures which are common in the real estate industry and are described in Note 5 of the condensed notes to consolidated financial statements. Our joint ventures typically fund their cash needs through secured debt financings obtained by and in the name of the joint venture entity. The joint venture debt is secured by a first mortgage, is without recourse to the joint venture partners, and does not represent a liability of the partners, except to the extent the partners or their affiliates expressly guarantee the joint venture debt. As of June 30, 2015, the Operating Partnership guaranteed joint venture related mortgage indebtedness of $319.9 million (of which we have a right of recovery from our joint venture partners of $96.7 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.

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 January 15, 2015, we acquired a 100% interest in Jersey Gardens (renamed The Mills at Jersey Gardens) in Elizabeth, New Jersey and University Park Village in Fort Worth, Texas, properties previously owned by Glimcher Realty Trust for $677.9 million of cash and the assumption of existing mortgage debt of $405.0 million.

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

On January 10, 2014, we acquired one of our partner's interests in a portfolio of ten properties for approximately $114.4 million, seven of which were previously consolidated.

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.

During the first six months of 2015, we disposed of our interests in two unconsolidated retail properties. The aggregate gain recognized on these transactions was approximately $16.3 million.

On April 13, 2015, we announced we had formed a joint venture with Sears, whereby Sears contributed 10 of its properties located at our malls to the newly formed joint venture in exchange for a 50% noncontrolling interest in this joint venture. We contributed $114.0 million in cash in exchange for a 50% noncontrolling interest in this joint venture. Sears or its affiliates are leasing back each of the 10 properties from the joint venture. The joint venture has the right to recapture not less than 50% of the space leased to Sears to be used for purposes of redeveloping and releasing the recaptured space. We will provide development, leasing and management services to the joint venture. On July 7, 2015, we separately invested approximately $33.0 million in exchange for 1,125,760 common shares of Seritage Growth Properties, a public REIT recently formed by Sears, which now holds their previous interest in the newly formed joint venture.

New Domestic Developments, Redevelopments and Expansions. During 2015, construction began on the following new Premium Outlet and new mall:

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, big box tenants, and restaurants, are underway at 28 properties.

Our share of the costs of all development and redevelopment projects currently under construction is approximately $2.3 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 2015 will be approximately $114 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 June 30, 2015 (in millions):

We paid a common stock dividend of $1.50 per share in the second quarter of 2015. Our Board of Directors declared a cash dividend for the third quarter of 2015 of $1.55 per share of common stock payable on August 31, 2015 to stockholders of record on August 17, 2015. We must pay a minimum amount of dividends to maintain our status as a REIT. 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.

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 its 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, uncertainties and other factors. Such factors include, but are not limited to: our ability to meet debt service requirements, the availability and terms of financing, changes in our credit rating, changes in market rates of interest and foreign exchange rates for foreign currencies, changes in value of investments in foreign entities, the ability to hedge interest rate and currency risk, risks associated with the acquisition, development, expansion, leasing and management of properties, general risks related to retail real estate, the liquidity of real estate investments, environmental liabilities, international, national, regional and local economic conditions, changes in market rental rates, security breaches that could 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, the intensely competitive market environment in the retail industry, costs of common area maintenance, risks related to international activities, insurance costs and coverage, the 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.

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 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:

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. We also include in FFO the impact of foreign currency exchange gains and losses, legal expenses, transaction expenses and other items required by GAAP.

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:

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

Sensitivity Analysis. We disclosed a qualitative and quantitative analysis regarding market risk in the Management's Discussion and Analysis of Financial Condition and Results of Operations included in our 2014 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, 2014.

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 June 30, 2015 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

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.

Through the period covered by this report, there were no material changes to the Risk Factors disclosed under Item 1A: Risk Factors in Part I of our 2014 Annual Report on Form 10-K.

During the quarter ended June 30, 2015, we issued 3,548 shares of common stock to three limited partners of the Operating Partnership in exchange for an equal number of units pursuant to the partnership agreement of the Operating Partnership, as follows:

In each case, the issuance of the shares of common stock was exempt from registration pursuant to Section 4(a)(2) of the Securities Act of 1933, as amended.

The following table summarizes repurchases of common stock settled during the three month period ended June 30, 2015:

During the quarter covered by this report, the Audit Committee of our Board of Directors approved certain audit, audit-related, and non-audit tax compliance and tax consulting services to be provided by Ernst & Young LLP, our independent registered public accounting firm.
