EXPLANATORY NOTE

            This report combines the quarterly reports on Form 10-Q for the quarterly period ended March 31, 2016 of Simon Property Group, Inc., a Delaware corporation, and Simon Property Group, L.P., a Delaware limited partnership. Unless stated otherwise or the context otherwise requires, references to "Simon" mean Simon Property Group, Inc. and references to the "Operating Partnership" mean Simon Property Group, L.P.. References to "we," "us" and "our" mean collectively Simon, the Operating Partnership and those entities/subsidiaries owned or controlled by Simon and/or the Operating Partnership.

            Simon is a real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended. We are structured as an umbrella partnership REIT under which substantially all of our business is conducted through the Operating Partnership, Simon's majority-owned partnership subsidiary, for which Simon is the general partner. As of March 31, 2016, Simon owned an approximate 85.5% ownership interest in the Operating Partnership, with the remaining 14.5% ownership interest owned by limited partners. As the sole general partner of the Operating Partnership, Simon has exclusive control of the Operating Partnership's day-to-day management.

            We operate Simon and the Operating Partnership as one business. The management of Simon consists of the same members as the management of the Operating Partnership. As general partner with control of the Operating Partnership, Simon consolidates the Operating Partnership for financial reporting purposes, and Simon has no material assets or liabilities other than its investment in the Operating Partnership. Therefore, the assets and liabilities of Simon and the Operating Partnership are the same on their respective financial statements.

            We believe that combining the quarterly reports on Form 10-Q of Simon and the Operating Partnership into this single report provides the following benefits:

•

enhances investors' understanding of Simon and the Operating Partnership by enabling investors to view the business as a whole in the same manner as management views and operates the business;



•

eliminates duplicative disclosure and provides a more streamlined presentation since substantially all of the disclosure in this report applies to both Simon and the Operating Partnership; and



•

creates time and cost efficiencies through the preparation of one combined report instead of two separate reports.

            We believe it is important for investors to understand the few differences between Simon and the Operating Partnership in the context of how we operate as a consolidated company. The primary difference is that Simon itself does not conduct business, other than acting as the general partner of the Operating Partnership and issuing equity or equity-related instruments from time to time. In addition, Simon itself does not incur any indebtedness, as all debt is incurred by the Operating Partnership or entities/subsidiaries owned or controlled by the Operating Partnership.

            The Operating Partnership holds, directly or indirectly, substantially all of our assets, including our ownership interests in our joint ventures. The Operating Partnership conducts all of our business and is structured as a partnership with no publicly traded equity. Except for the net proceeds from equity issuances by Simon, which are contributed to the capital of the Operating Partnership in exchange for, in the case of common stock issuances by Simon, common units of partnership interest in the Operating Partnership, or units, or, in the case of preferred stock issuances by Simon, preferred units of partnership interest in the Operating Partnership, or preferred units, the Operating Partnership, directly or indirectly, generates the capital required by our business through its operations, the incurrence of indebtedness, proceeds received from the disposition of certain properties and joint ventures and the issuance of units or preferred units to third parties.

            The presentation of stockholders' equity, partners' equity and noncontrolling interests are the main areas of difference between the consolidated financial statements of Simon and those of the Operating Partnership. The differences between stockholders' equity and partners' equity result from differences in the equity issued at the Simon and Operating Partnership levels. The units held by limited partners in the Operating Partnership are accounted for as partners' equity in the Operating Partnership's financial statements and the units held by limited partners are accounted for as noncontrolling interests in Simon's financial statements. The noncontrolling interests in the Operating Partnership's financial statements include the interests of unaffiliated partners in various consolidated partnerships. The noncontrolling interests in Simon's financial statements include the same noncontrolling interests at the Operating Partnership level and, as previously stated, the units held by limited partners of the Operating Partnership. Although classified differently, total equity of Simon and the Operating Partnership is the same.

Table of Contents

            To help investors understand the differences between Simon and the Operating Partnership, this report provides:

•

separate consolidated financial statements for Simon and the Operating Partnership;



•

a single set of condensed notes to such consolidated financial statements that includes separate discussions of noncontrolling interests and stockholders' equity or partners' equity, accumulated other comprehensive income (loss) and per share and per unit data, as applicable,



•

a combined Management's Discussion and Analysis of Financial Condition and Results of Operations section that also includes discrete information related to each entity; and



•

Separate Part II, Item 2. Unregistered Sales of Equity Securities and Use of Proceeds sections.

            This report also includes separate Part I, Item 4. Controls and Procedures sections and separate Exhibits 31 and 32 certifications for each of Simon and the Operating Partnership in order to establish that the requisite certifications have been made and that Simon and the Operating Partnership are each compliant with Rule 13a-14(a) or Rule 15d-14(a) of the Securities Exchange Act of 1934 and 18 U.S.C. §1350. The separate discussions of Simon and the Operating Partnership in this report should be read in conjunction with each other to understand our results on a consolidated basis and how management operates our business.

            In order to highlight the differences between Simon and the Operating Partnership, the separate sections in this report for Simon and the Operating Partnership specifically refer to Simon and the Operating Partnership. In the sections that combine disclosure of Simon and the Operating Partnership, this report refers to actions or holdings as being actions or holdings of "we," "us" or "ours." Although the Operating Partnership is generally the entity that directly or indirectly enters into contracts and joint ventures, holds assets and incurs debt, we believe that reference to "we," "us" or "our" in this context is appropriate because the business is one enterprise and we operate the business through the Operating Partnership.

1. Organization

            Simon Property Group, Inc. 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 distribute not less than 100% of their REIT taxable income. Simon Property Group, L.P. is our majority-owned Delaware partnership subsidiary that owns all of our real estate properties and other assets. In these condensed notes to the consolidated financial statements, unless stated otherwise or the context otherwise requires, references to "Simon" mean Simon Property Group, Inc. and references to the "Operating Partnership" mean Simon Property Group, L.P.. References to "we", "us" and "our" mean collectively Simon, the Operating Partnership and those entities/subsidiaries owned or controlled by Simon and/or the Operating Partnership. Unless otherwise indicated, these condensed notes to consolidated financial statements apply to both Simon and the Operating Partnership. According to the Operating Partnership's partnership agreement, the Operating Partnership is required to pay all expenses of Simon.

            We own, develop and manage retail real estate properties, which consist primarily of malls, Premium Outlets®, and The Mills®. As of March 31, 2016, we owned or held an interest in 208 income-producing properties in the United States, which consisted of 107 malls, 70 Premium Outlets, 14 Mills, four lifestyle centers, and 13 other retail properties in 37 states and Puerto Rico. Internationally, as of March 31, 2016, 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. We also own an interest in six Designer Outlet properties in Europe and one Designer Outlet property in Canada, of which two properties are consolidated. Of the six properties in Europe, two are located in Italy and one each is located in Austria, Germany, the Netherlands, and the United Kingdom. As of March 31, 2016, we also 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.

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 March 31, 2016 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 the separate 2015 Annual Reports on Form 10-K of Simon and the Operating Partnership.

            As of March 31, 2016, we consolidated 136 wholly-owned properties and 15 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 investments in Klépierre and HBS Global Properties, or HBS, 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 57 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, Germany, Italy, Canada, and the United Kingdom comprise 19 of the remaining 23 properties. These international properties are managed 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 in the Operating Partnership, 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 Simon 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. Simon's weighted average ownership interest in the Operating Partnership was 85.6% and 85.5% for the three months ended March 31, 2016 and 2015, respectively. As of March 31, 2016 and December 31, 2015, Simon's 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 net assets of the Operating Partnership.

            Preferred unit requirements in the Operating Partnership's accompanying consolidated statements of operations and comprehensive income represent distributions on outstanding preferred units and are recorded when declared.

Reclassifications

            We made certain reclassifications of prior period amounts in the consolidated financial statements to conform to the 2016 presentation. These reclassifications had no impact on previously reported net income attributable to common stockholders or unitholders or earnings per share or per unit.

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 of high credit quality. However, at certain times, such cash and cash equivalents are in excess of Federal Deposit Insurance Corporation and Securities Investor Protection Corporation 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 March 31, 2016 and December 31, 2015, we had marketable securities of $192.3 million and $183.8 million, respectively, 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 as of March 31, 2016 and December 31, 2015 were approximately $24.1 million and $12.6 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

and where indicated in millions or billions)

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 March 31, 2016 and December 31, 2015, we had investments of $187.8 million and $181.4 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. No material adjustment in the carrying value was required for the three months ended March 31, 2016.

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 March 31, 2016 and December 31, 2015 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 foreign currency forward contracts with a gross liability balance of $8.1 million at March 31, 2016 and a gross asset value of $21.4 million and $27.8 million at March 31, 2016 and December 31, 2015, respectively.

            Note 6 includes a discussion of the fair value of debt measured using Level 2 inputs. Notes 5 and 9 include discussions 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.

Noncontrolling Interests

Simon

            Details of the carrying amount of Simon's noncontrolling interests are as follows:

            Net income attributable to noncontrolling interests (which includes nonredeemable and redeemable noncontrolling interests in consolidated properties, limited partners' interests in the Operating Partnership 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.

and where indicated in millions or billions)

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

The Operating Partnership

            Our evaluation of the appropriateness of classifying the Operating Partnership's common units of partnership interest, or units, held by Simon and the Operating Partnership's limited partners within permanent equity considered several significant factors. First, as a limited partnership, all decisions relating to the Operating Partnership's operations and distributions are made by Simon, acting as the Operating Partnership's sole general partner. The decisions of the general partner are made by Simon's Board of Directors or management. The Operating Partnership has no other governance structure. Secondly, the sole asset of Simon is its interest in the Operating Partnership. As a result, a share of common stock of Simon, or common stock, if owned by the Operating Partnership, is best characterized as being similar to a treasury share and thus not an asset of the Operating Partnership.

            Limited partners of the Operating Partnership have the right under the Operating Partnership's partnership agreement to exchange their units for shares of common stock or cash, as selected by Simon as the sole general partner. Accordingly, we classify units held by limited partners in permanent equity because Simon may elect to issue shares of common stock to limited partners exercising their exchange rights rather than using cash. Under the Operating Partnership's partnership agreement, the Operating Partnership is required to redeem units held by Simon only when Simon has repurchased shares of common stock. We classify units held by Simon in permanent equity because the decision to redeem those units would be made by Simon.

            Net income attributable to noncontrolling interests (which includes nonredeemable and redeemable noncontrolling interests in consolidated properties) is a component of consolidated net income. During the three months ended March 31, 2016 and 2015, no individual components of other comprehensive income (loss) were attributable to noncontrolling nonredeemable interests (deficit) in properties.

            The reclassifications out of accumulated other comprehensive income (loss) consisted of the following during the three months ended March 31, 2016 and 2015:

Derivative Financial Instruments

            We record all derivatives on our consolidated balance sheets 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.

            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 U.S. dollars for their fair value at or close to their settlement date.

            We had the following Euro:USD forward contracts at March 31, 2016 and December 31, 2015 (in millions):

            Asset balances in the above table are included in deferred costs and other assets and liability balances are recorded in other liabilities within the consolidated financial statements. We have designated the above as net investment hedges. Accordingly, we 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 loss related to our derivative activities, including our share of the other comprehensive loss from joint venture properties, approximated $29.6 million and $17.7 million as of March 31, 2016 and December 31, 2015, respectively.

New Accounting Pronouncements

            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 delayed 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 of 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 Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2015-02, "Amendments to the Consolidation Analysis." ASU 2015-02 makes changes to both the variable interest model and the voting model. We adopted this standard as required on January 1, 2016. All reporting entities involved with limited partnerships and similar entities were required to re-evaluate whether these entities, including the Operating Partnership, are subject to the variable interest model or the voting model and whether they qualify for consolidation. The adoption of the new standard did not result in any material changes to our consolidated financial statements or disclosures, including the disclosures related to the Operating Partnership.

            In April 2015, the FASB issued ASU 2015-03, "Simplifying the Presentation of Debt Issuance Costs. 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. We adopted this standard as required on January 1, 2016 resulting in a reclassification of $85.5 million from deferred costs and other assets to a reduction of the carrying amount of mortgages and other unsecured indebtedness.

            In September 2015, the FASB issued ASU 2015-16, "Simplifying the Accounting for Measurement-Period Adjustments," which requires adjustments to provisional amounts used in business combinations during the measurement period to be recognized in the reporting period in which the adjustment amounts are determined. It also requires the disclosure of the impact on changes in estimates on earnings, depreciation, amortization and other income effects. We adopted this standard as required on January 1, 2016. The adoption of this standard did not have an impact on our consolidated financial statements.

and where indicated in millions or billions)

            In January 2016, the FASB issued ASU 2016-01, "Financial Instruments — Overall: Recognition and Measurement of Financial Assets and Financial Liabilities," which will require entities to measure their investments at fair value and recognize any changes in fair value in net income unless the investments qualify for the new practicability exception. The practicability exception will be available for equity investments that do not have readily determinable fair values. The guidance will be effective for us beginning with the first quarter of 2018. We are currently evaluating the impact of adopting the new standard will have on our consolidated financial statements.

            In February 2016, the FASB issued ASU 2016-02, "Leases", which is expected to result in lessee's recognizing most leased assets on the balance sheet. Lessor accounting will remain substantially similar to the current accounting, however certain refinements were made to conform the standard with the recently issued revenue recognition guidance in ASU 2014-09. ASU 2016-02 will be effective for us retrospectively for annual and interim periods beginning after December 15, 2018. We are currently evaluating the impact adopting the new standard will have on our consolidated financial statements.

            In March 2016, the FASB issued ASU 2016-07, "Investments — Equity Method and Joint Ventures", eliminating the requirement for retrospective application of equity method accounting when an investment previously accounted for by another method initially qualifies for the equity method. This standard will be effective for us retrospectively for annual and interim periods beginning after December 15, 2016. We do not expect the adoption of this new standard will have an impact on our consolidated financial statements.

4. Per Share and Per Unit Data

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

            For the three months ended March 31, 2016, potentially dilutive securities include units that are exchangeable for common stock and long-term incentive performance units, 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 material dilutive effect for the three months ended March 31, 2016 and 2015. We have not adjusted net income attributable to common stockholders and weighted average shares outstanding for income allocable to limited partners or limited partner units, respectively, as doing so would have no dilutive impact. We accrue dividends when they are declared.

The Operating Partnership

            For the three months ended March 31, 2016, potentially dilutive securities include LTIP units. No securities had a material dilutive effect for the three months ended March 31, 2016 and 2015. We accrue distributions 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 80 properties as of March 31, 2016.

            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 March 31, 2016 and December 31, 2015, we had construction loans and other advances to related parties totaling $22.4 million and $13.9 million, respectively, which are included in deferred costs and other assets in the accompanying consolidated balance sheets.

Unconsolidated Property Transactions

            On July 22, 2015, we closed on our previously announced transaction with Hudson's Bay Company, or HBC, to which HBC contributed 42 properties in the U.S. 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 entity, HBS. As of March 31, 2016, we have funded $5.7 million of this commitment. On September 30, 2015, HBC announced it had closed on the acquisition of Galeria Holding, the parent company of Germany's leading department store, Kaufhof. In conjunction with the closing, HBS acquired 41 Kaufhof properties in Germany from HBC. All of these properties have been leased to affiliates of HBC. We contributed an additional $178.5 million to HBS upon closing of the Galeria Holding transaction. Our noncontrolling equity interest in HBS is approximately 9.2% at March 31, 2016. Our share of net income, net of amortization of our excess investment, was $1.1 million for the three months ended March 31, 2016. Total assets and total liabilities of HBS as of March 31, 2016 were $4.3 billion and $2.9 billion, respectively, and total revenues, operating income and consolidated net income were approximately $89.0 million, $37.3 million, and $12.2 million, respectively, for the three months ended March 31, 2016.

            On April 13, 2015, we announced a joint venture with Sears Holdings, or Sears, whereby Sears contributed 10 of its properties located at our malls to the joint venture in exchange for a 50% noncontrolling interest in the joint venture. We contributed $114.0 million in cash in exchange for a 50% noncontrolling interest in the 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 for any recaptured space. On July 7, 2015, we

separately invested approximately $33.0 million in exchange for 1,125,760 common shares of Seritage Growth Properties, or Seritage, a public REIT formed by Sears, which we account for as an available-for-sale security. Seritage now holds Sears' interest in the joint venture.

European Investments

            At March 31, 2016, we owned 63,924,148 shares, or approximately 20.3%, of Klépierre, which had a quoted market price of $47.72 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% resulting in a non-cash gain of $206.9 million for the first quarter of 2015 as if we had sold a proportionate share of our investment. 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 this additional purchase has been determined to relate to investment property. Our share of net income, net of amortization of our excess investment, was $13.0 million and $6.1 million for the three months ended March 31, 2016 and 2015, 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 $342.7 million, $98.8 million and $44.2 million, respectively, for the three months ended March 31, 2016 and $332.5 million, $141.6 million and $72.0 million, respectively, for the three months ended March 31, 2015.

            We have an interest in a European entity that had interests in six Designer Outlet properties as of December 31, 2015. In addition, we have a noncontrolling interest in a European property management and development company. As of March 31, 2016, our legal percentage ownership interests in these entities ranged from 45% to 90%. We obtained control of the entity requiring a remeasurement of our previously held equity interest to fair value and a corresponding non-cash gain of $12.1 million in earnings during the first quarter of 2016, which includes amounts reclassified from accumulated other comprehensive income (loss) related to the currency translation adjustment previously recorded on our investment. The gain is 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. As a result of the change in control, we now consolidate two of the six outlet properties. The consolidation required us to recognize the entity's identifiable assets and liabilities at fair value in our consolidated financial statements along with the related redeemable noncontrolling interest representing our partners' share. The fair value of the consolidated assets and liabilities relates primarily to investment property, investments in unconsolidated entities and assumed mortgage debt. Due to certain redemption rights held by our venture partner, the noncontrolling interest is presented on the accompanying Simon consolidated balance sheet outside of equity in limited partners' preferred interest in the Operating Partnership and noncontrolling redeemable interests in properties and in the accompanying Operating Partnership consolidated balance sheet in preferred units, various series, at liquidation value, and noncontrolling redeemable interests in properties. In February 2016 we and our partner, through this European entity, acquired a noncontrolling 75.0% ownership interest in an outlet center in Ochtrup, Germany for cash consideration of approximately $38.3 million.

            We also have minority interests in Value Retail PLC and affiliated entities, which own or have interests in and operate nine luxury outlets located throughout Europe and we have a direct minority ownership in three of those outlets. Our investment in these entities is accounted for under the cost method. At both March 31, 2016 and December 31, 2015, 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.

Asian Joint Ventures

            We conduct our international Premium Outlet operations in Japan through a joint venture with Mitsubishi Estate Co., Ltd. We have a 40% ownership interest in this joint venture. The carrying amount of our investment in this joint

venture was $240.0 million and $224.6 million as of March 31, 2016 and December 31, 2015, respectively, including all related components of accumulated other comprehensive income (loss). We conduct our international Premium Outlet operations in South Korea through a joint venture with Shinsegae International Co. We have a 50% ownership interest in this joint venture. The carrying amount of our investment in this joint venture was $119.8 million and $117.0 million as of March 31, 2016 and December 31, 2015, respectively, including all related components of accumulated other comprehensive income (loss).

Summary Financial Information

            A summary of our equity method investments and share of income from such investments, excluding Klépierre and HBS, follows.

BALANCE SHEETS

            "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.

6. Debt

Unsecured Debt

            At March 31, 2016, our unsecured debt consisted of $14.8 billion of senior unsecured notes of the Operating Partnership, net of discounts, $634.7 million outstanding under the Operating Partnership's $4.0 billion unsecured revolving

credit facility, or Credit Facility, $50.0 million outstanding under the Operating Partnership's $2.75 billion supplemental unsecured revolving credit facility, or Supplemental Facility, and together with the Credit Facility, the Credit Facilities, and $975.4 million outstanding under the Operating Partnership's global unsecured commercial paper note program, or the Commercial Paper program. The March 31, 2016 balance on the Credit Facility included $246.5 million (U.S. dollar equivalent) of Euro-denominated borrowings and $198.1 million (U.S. dollar equivalent) of Yen-denominated borrowings. At March 31, 2016, the outstanding amount under the Commercial Paper program was $975.4 million, of which $195.0 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 March 31, 2016, we had an aggregate available borrowing capacity of $5.1 billion under the Credit Facility and Supplemental Facility. The maximum aggregate outstanding balance under the Credit Facilities during the three months ended March 31, 2016 was $1.2 billion and the weighted average outstanding balance was $568.8 million. Letters of credit of $6.8 million were outstanding under the Credit Facilities as of March 31, 2016.

            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, subject to our continued compliance with the terms thereof. The base interest rate on the Credit Facility is LIBOR plus 80 basis points with an additional facility fee of 10 basis points.

            On April 6, 2016, the Operating Partnership amended the Supplemental Facility to, among other matters, (i) exercise its $750.0 million accordion feature such that the Supplemental Facility's borrowing capacity has been increased from $2.75 billion to $3.50 billion and (ii) permit us to further increase the Supplemental Facility's borrowing capacity to $4.25 billion during its term. The initial maturity date of the Supplemental Facility is June 30, 2019 and can be extended for an additional year to June 30, 2020 at our sole option, subject to our continued compliance with the terms thereof. The base interest rate on the Supplemental Facility is LIBOR plus 80 basis points with an additional facility fee of 10 basis points. The Supplemental Facility provides for borrowings denominated in U.S. dollars, Euro, Yen, Sterling, Canadian dollars and Australian dollars.

            The maximum aggregate program size of the Commercial Paper program is $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. The Commercial Paper program is supported by the Credit Facility and the Supplemental Facility and if necessary or appropriate, we may make one or more draws under either the Credit Facility or the Supplemental Facility to pay amounts outstanding from time to time on the Commercial Paper program. On March 31, 2016, we had $975.4 million outstanding under the Commercial Paper program, comprised of $780.4 million outstanding in U.S. dollar denominated notes and $195.0 million (U.S. dollar equivalent) of Euro denominated notes with weighted average interest rates of 0.53% and 0.02%, respectively. The borrowings mature on various dates from June 10, 2016 to June 24, 2016 and reduce amounts otherwise available under the Credit Facilities.

            On January 13, 2016, the Operating Partnership issued $550.0 million of senior unsecured notes at a fixed interest rate of 2.50% with a maturity date of July 15, 2021 and $800.0 million of senior unsecured notes at a fixed interest rate of 3.30% with a maturity date of January 15, 2026. Proceeds from the unsecured notes offering were used to pay down the Credit Facility, unencumber three properties and redeem senior unsecured notes at par in February 2016.

            During the three months ended March 31, 2016, the Operating Partnership redeemed at par $163.3 million of senior unsecured notes with a fixed interest rate of 6.10%.

Mortgage Debt

            Total mortgage indebtedness was $6.6 billion at March 31, 2016 and December 31, 2015.

            During the three months ended March 31, 2016, we repaid $373.1 million in mortgage loans, with a weighted average interest rate of 8.00%, unencumbering three properties.

            On January 1, 2016, as discussed in Note 5, we consolidated the European entity that held our interests in six Designer Outlet properties, as we obtained control of the entity. This resulted in the consolidation of two of the six operating properties — Parndorf Designer Outlet and Roermond Designer Outlet, subject to existing fixed rate mortgage loans of $104.3 million and $204.0 million, respectively, (both amounts U.S. dollar equivalent). The loans mature on May 20, 2022 and December 1, 2021 and bear interest at 1.95% and 1.86%, respectively.

Covenants

            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 March 31, 2016, we were in compliance with all covenants of our unsecured debt.

            At March 31, 2016, we are the borrowers under 45 non-recourse mortgage notes secured by mortgages on 48 properties, including two separate pools of cross-defaulted and cross-collateralized mortgages encumbering a total of five 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 that serve as collateral for that debt. If the applicable borrower under these non-recourse mortgage notes fails to comply with these covenants, the lender could accelerate the debt and enforce its right against their collateral. At March 31, 2016, 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, liquidity or results of operations.

Fair Value of Debt

            The carrying values of our variable-rate mortgages and other loans approximate 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 including commercial paper was $21.8 billion and $20.4 billion as of March 31, 2016 and December 31, 2015, respectively. The fair values of these financial instruments and the related discount rate assumptions as of March 31, 2016 and December 31, 2015 are summarized as follows:

7. Equity

            During the three months ended March 31, 2016, Simon issued 1,095 shares of common stock to a limited partner of the Operating Partnership in exchange for an equal number of units pursuant to the partnership agreement of the Operating Partnership. This transaction increased Simon's ownership interest in the Operating Partnership.

            On April 2, 2015, Simon's Board of Directors authorized Simon to repurchase up to $2.0 billion of common stock over a twenty-four month period as market conditions warrant. Simon may repurchase the shares in the open market or in privately negotiated transactions. During the first quarter of 2016, no purchases were made as part of this program. As Simon repurchases shares under this program, the Operating Partnership repurchases an equal number of units from Simon.

Temporary Equity

Simon

            We classify as temporary equity those securities for which there is the possibility that we could be required to redeem the security for cash irrespective of the probability of such a possibility. As a result, we classify one series of preferred units of the Operating Partnership and noncontrolling redeemable interests in properties in temporary equity. Each of these securities is discussed further below.

            Limited Partners' Preferred Interest in the Operating Partnership and Noncontrolling Redeemable Interests in Properties.    The redemption features of the preferred units of the Operating Partnership contain provisions which could require us to settle the redemption in cash. As a result, this series of preferred units in the Operating Partnership remains classified outside permanent equity. The remaining interests in a property or portfolio of properties that are redeemable at the option of the holder or in circumstances that may be outside our control are accounted for as temporary equity within limited partners' preferred interest in the Operating Partnership and noncontrolling redeemable interests in properties in the accompanying consolidated balance sheets. The carrying amount of the noncontrolling interest is adjusted to the redemption amount assuming the instrument is redeemable at the balance sheet date. Changes in the redemption value of the underlying noncontrolling interest are recorded within accumulated deficit. There are no noncontrolling interests redeemable at amounts in excess of fair value. The preferred units of the Operating Partnership and the amount of the noncontrolling redeemable interests in properties are summarized as follows:

preferred units and noncontrolling redeemable interests in properties in temporary equity. The carrying values for those securities classified in temporary equity are summarized as follows:

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, 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 Simon's Board of Directors, or the 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 second and third 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 and earnings per unit.

            The Compensation Committee approved LTIP unit 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 $6.4 million and $6.2 million for the three months ended March 31, 2016 and 2015, respectively.

            Restricted Stock.    We recorded compensation expense, net of capitalization, related to restricted stock of approximately $2.4 million and $2.1 million for the three months ended March 31, 2016 and 2015, 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 Chief Executive Officer, 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 performance criteria of the Current Award are based on the attainment of certain specified funds from operations per share as defined by and as set forth in the Current Award. 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 on December 31, 2015, December 31, 2016 and December 31, 2017, respectively. Based on the Company's performance in 2015, 360,000 A units were earned. The earned A units will vest on January 1, 2018, earned B units, if any, will vest on January 1, 2019 and earned C units, if any, 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.

8. Commitments and Contingencies

Litigation

            We are involved from time-to-time in various legal and regulatory 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 such as acquisitions and divestitures. We believe that our current proceedings will not have a material adverse effect on our financial condition, liquidity or 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 primary insurer and remediation and restoration work has been completed. The property re-opened on March 29, 2012. The excess insurance carriers (those providing coverage above $50 million) 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. 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 and August 2015, trial on the damages portion of our claim was completed and the jury entered a verdict for damages in the amount of $204.1 million (inclusive of the $50.0 million previously paid by the primary carrier). In April 2016, the court entered final judgment in the amount of the jury verdict and it will bear interest from the date of the jury's verdict. We will continue our efforts through the conclusion of the 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.

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 March 31, 2016 and December 31, 2015, the Operating Partnership guaranteed joint venture related mortgage indebtedness of $308.8 million and $353.7 million, respectively (of which we have a right of recovery from our joint venture partners of $76.5 million and $112.8 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

            As discussed in Note 5, on January 1, 2016 we obtained control of the European entity that held our interest in six Designer Outlet properties, requiring a remeasurement of our previously held equity interest to fair value and a corresponding non-cash gain of $12.1 million and which also resulted in the consolidation of two of the six properties, which had been previously unconsolidated. In February 2016, we and our partner, through this European entity, acquired a noncontrolling 75.0% ownership interest in an outlet center in Ochtrup, Germany for cash consideration of approximately $38.3 million.

            During January of 2016, we disposed of our interests in two residential investments and a consolidated retail property. Our share of the gross proceeds from these transactions was $72.4 million. The gain on the consolidated retail property was $10.6 million. The aggregate gain of $36.9 million from the sale of the two residential investments is included in other income and resulted in an additional $7.2 million in taxes included in income and other taxes.

            On April 14, 2016, we and our joint venture partner, Invesco Real Estate, acquired The Shops at Crystals, a 324,000 square foot luxury retail property located at the entryway of CityCenter in Las Vegas, Nevada, for an acquisition price of approximately $1.1 billion. We have a 50% noncontrolling interest in this venture.

            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 and the determination of fair value was finalized during the fourth quarter of 2015 resulting in a valuation of investment property of $1.1 billion, net lease related intangibles of $3.6 million and mortgage debt premiums of $17.9 million. We amortize these amounts over the estimated 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 maturities, respectively.

            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 three 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. Other than these transaction costs, we incurred a minimal amount of transaction expenses during the three months ended March 31, 2016 and 2015.

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. 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 distribute not less than 100% of their REIT taxable income. Simon Property Group, L.P. is our majority-owned Delaware partnership subsidiary that owns all of our real estate properties and other assets. In this discussion, unless stated otherwise or the context otherwise requires, references to "Simon" mean Simon Property Group, Inc. and references to the "Operating Partnership" mean Simon Property Group, L.P.. References to "we", "us" and "our" mean collectively Simon, the Operating Partnership and those entities/subsidiaries owned or controlled by Simon and/or the Operating Partnership. According to the Operating Partnership's partnership agreement, the Operating Partnership is required to pay all expenses of Simon.

            We own, develop and manage retail real estate properties, which consist primarily of malls, Premium Outlets®, and The Mills®. As of March 31, 2016, we owned or held an interest in 208 income-producing properties in the United States, which consisted of 107 malls, 70 Premium Outlets, 14 Mills, four lifestyle centers, and 13 other retail properties in 37 states and Puerto Rico. In addition, we have redevelopment and expansion projects, including the addition of anchors, big box tenants, and restaurants, underway at over 30 properties in the United States and we have two outlets and two other significant retail projects under development. Internationally, as of March 31, 2016, 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. We also own an interest in six Designer Outlet properties in Europe and one Designer Outlet property in Canada, of which two properties are consolidated. Of the six properties in Europe, two are located in Italy and one each is located in Austria, Germany, the Netherlands, and the United Kingdom. We also have three international outlet properties under development. As of March 31, 2016, we also 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:

•

base minimum rents,



•

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

Table of Contents

•

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 outlet properties.

            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, portfolio NOI and comparable property NOI (NOI for properties owned and operated 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 share and diluted earnings per unit decreased $0.18 during the first three months of 2016 to $1.55 from $1.73 for the same period last year. The decrease in diluted earnings per share and diluted earnings per unit was primarily attributable to:

•

a 2015 non-cash gain on Klépierre's acquisition of Corio N.V., or Corio, of $206.9 million, or $0.57 per diluted share/unit, partially offset by



•

improved operating performance and core business fundamentals in 2016 and the impact of our acquisition and expansion activity,



•

a 2016 gain on acquisitions and disposals of $22.7 million, or $0.06 per diluted share/unit, related to a non-cash gain on the consolidation of additional properties of $12.1 million, or $0.03 per diluted share/unit, and a gain on the sale of our interest in a property of $10.6 million, or $0.03 per diluted share/unit,



•

a 2016 gain related to the disposition of our interest in two multi-family residential investments of $29.7 million, net of taxes, or $0.08 per diluted share/unit, and



•

decreased interest expense in 2016 of $13.0 million, or $0.04 per diluted share/unit.

            Core business fundamentals during the first three months of 2016 improved compared to the first three months of 2015, primarily driven by strong leasing activity. Portfolio NOI grew by 7.8% for the three month period in 2016 over the prior year period. Comparable property NOI grew 5.1% for our portfolio of U.S. Malls, Premium Outlets, Lifestyle Centers and The Mills. Total sales per square foot, or psf, decreased 1.3% from $621 psf at March 31, 2015 to $613 psf at March 31, 2016, for our U.S. Malls and Premium Outlets. Average base minimum rent for U.S. Malls and Premium Outlets increased 4.4% to $49.70 psf as of March 31, 2016, from $47.59 psf as of March 31, 2015. 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 $10.24 psf ($68.84 openings compared to $58.60 closings) as of March 31, 2016, representing a 17.5% increase over expiring payments. Ending occupancy for our U.S. Malls and Premium Outlets was 95.6% as of March 31, 2016, as compared to 95.8% as of March 31, 2015, a decrease of 20 basis points.

            Our effective overall borrowing rate at March 31, 2016 on our consolidated indebtedness decreased 55 basis points to 3.76% as compared to 4.31% at March 31, 2015. This reduction was primarily due to a decrease in the effective overall borrowing rate on fixed rate debt of 72 basis points (3.89% at March 31, 2016 as compared to 4.61% at March 31, 2015) offset by an increase in the effective overall borrowing rate on variable rate debt of 32 basis points (1.60% at March 31, 2016 as compared to 1.28% at March 31, 2015). At March 31, 2016, the weighted average years to maturity of our consolidated indebtedness was 6.1 years as compared to 5.9 years at December 31, 2015. Our financing activities for the three months ended March 31, 2016 included:

•

Decreasing our USD denominated borrowings by $625.0 million on the Operating Partnership's $4.0 billion unsecured revolving credit facility, or Credit Facility.



•

Increasing our USD denominated borrowings by $50.0 million on the Operating Partnership's $2.75 billion supplemental unsecured revolving credit facility, or Supplemental Facility, and together with the Credit Facility, the Credit Facilities.



•

Increasing our borrowings under the Operating Partnership's global unsecured commercial paper note program, or the Commercial Paper program, by $89.8 million through the issuance of U.S. dollar denominated notes.



•

Issuing, on January 13, 2016, $550.0 million of senior unsecured notes at a fixed annual interest rate of 2.50% with a maturity date of July 15, 2021 and $800.0 million of senior unsecured notes at a fixed annual interest rate of 3.30% with a maturity date of January 15, 2026.



•

Redeeming at par $163.3 million of senior unsecured notes with a fixed interest rate of 6.10%.



•

Unencumbering three properties by repaying $373.1 million in mortgage loans.



•

Repaying our $240.0 million unsecured term loan.

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. For comparative purposes, we separate the information related to The Mills from our other U.S. operations. We also do not include any information for properties located outside 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.

Table of Contents

            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 stores with less than 20,000 square feet 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 three months ended March 31, 2016, we signed 174 new leases and 551 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 2.5 million square feet, of which 1.9 million square feet related to consolidated properties. During the comparable period in 2015, we signed 192 new leases and 308 renewal leases with a fixed minimum rent, comprising approximately 1.6 million square feet, of which 1.1 million square feet related to consolidated properties. The average annual initial base minimum rent for new leases was $52.74 per square foot in 2016 and $57.66 per square foot in 2015 with an average tenant allowance on new leases of $40.22 per square foot and $50.97 per square foot, respectively.

Japan Data

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

Results of Operations

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

•

During the first quarter of 2016, we consolidated two Designer Outlet properties in Europe that had previously been accounted for under the equity method.



•

During the first quarter of 2016, we disposed of one retail property.



•

On October 29, 2015, we opened Tampa Premium Outlets, a 441,000 square foot outlet center in Lutz (Tampa), Florida.



•

On October 1, 2015, we opened Tucson Premium Outlets, a 366,000 square foot outlet center in Marana (Tucson), Arizona.



•

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.

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

•

On February 1, 2016, we and our partner acquired a 75.0% noncontrolling interest in an outlet center in Ochtrup, Germany.



•

During the third quarter of 2015, we closed on our previously announced transaction with Hudson's Bay Company, or HBC, whereby we currently have an 9.2% noncontrolling interest in a newly formed entity, HBS Global Properties, or HBS. HBC contributed 42 of its properties in the U.S. to HBS. Later in the third quarter of 2015, HBS acquired an additional 41 properties in Germany concurrently with HBC's acquisition of Galeria Holding, the parent company of Germany's leading department store, Kaufhof, as further discussed in Note 5 of the condensed notes to our consolidated financial statements. All of the HBS properties have been leased to affiliates of HBC.



•

On August 13, 2015, we and our partner opened Gloucester Premium Outlets, a 370,000 square foot outlet center. We have a 50% noncontrolling interest in this new center.



•

On July 9, 2015, we and our partner opened Vancouver Designer Outlet, a 242,000 square foot outlet center. We have a 45% noncontrolling interest in this new center.



•

During the second quarter of 2015, we formed a joint venture with Sears Holdings, or Sears, whereby we have a 50% noncontrolling interest in a joint venture in which Sears contributed 10 of its properties located at our malls. Seritage Growth Properties, or Seritage, now holds Sears' interest in the joint venture.



•

During 2015, we disposed of our interests in three retail properties.

            For the purposes of the following comparison between the three months ended March 31, 2016 and 2015, 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 March 31, 2016 vs. Three months ended March 31, 2015

            Minimum rents increased $65.1 million during 2016, of which the property transactions accounted for $13.7 million of the increase. Comparable rents increased $51.4 million, or 6.9%, primarily attributable to an increase in base minimum rents as well as incremental revenue from our expansion activity. Overage rent decreased $10.0 million as a result of decreased tenant sales and an increase in the overage breakpoints as compared to 2015.

            Tenant reimbursements increased $31.4 million, due to a $4.9 million increase attributable to the property transactions and a $26.5 million, or 7.9%, increase in the comparable properties. The majority of the increase in the comparable properties resulted from additional marketing recoveries which entirely offset the $16.3 million increase in advertising and promotion expense. The remainder of the increase was primarily due to annual fixed contractual increases related to common area maintenance and real estate tax recoveries.

            Total other income increased $35.7 million, primarily as a result of a $36.9 million pre-tax gain on the sale of our investments in two multi-family residential investments, partially offset by a $3.5 million decrease in interest and dividend income.

36

---

Table of Contents

            Depreciation and amortization expense increased $12.5 million primarily due to the additional depreciable assets related to the property transactions and our continued redevelopment and expansion activities.

            Interest expense decreased $13.0 million primarily due to the net impact of our financing activities during 2016 and 2015 and the reduction in our effective overall borrowing rate as previously discussed.

            Income and other taxes increased $8.8 million as a result of taxes due on the sale of one of the multi-family residential investments.

            Income from unconsolidated entities increased $25.8 million primarily due to favorable results of operations and financing activity of joint venture properties as well as our acquisition and development activity.

            During 2016, we recorded a gain on the sale of a consolidated property of $10.6 million and recorded a non-cash remeasurement gain of $12.1 million related to the change in control of our interest in the European outlet properties as further discussed in Note 3 of the accompanying condensed notes to consolidated financial statements. During 2015, we recorded a $206.9 million non-cash gain on Klépierre's acquisition of Corio, as discussed in Note 3.

            Simon's net income attributable to noncontrolling interests decreased $10.5 million due to a decrease 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 comprised only 5.7% of our total consolidated debt at March 31, 2016. 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 $786.3 million during the three months ended March 31, 2016. In addition, the Credit Facilities and the Commercial Paper program provide alternative sources of liquidity as our cash needs vary from time to time. Borrowing capacity under these sources may be increased as discussed further below.

            Our balance of cash and cash equivalents increased $103.9 million during the first three months of 2016 to $805.1 million as of March 31, 2016 as further discussed in "Cash Flows" below.

            On March 31, 2016, we had an aggregate available borrowing capacity of $5.1 billion under the Credit Facilities, net of outstanding borrowings of $684.7 million and amounts outstanding under the Commercial Paper program of $975.4 million and letters of credit of $6.8 million. For the three months ended March 31, 2016, the maximum aggregate amount outstanding under the Credit Facilities was $1.2 billion and the weighted average amount outstanding was $568.8 million. The weighted average interest rate was 0.94% for the three months ended March 31, 2016. Further, on April 6, 2016, the Operating Partnership amended the Supplemental Facility to, among other matters, (i) exercise its $750.0 million accordion feature such that the Supplemental Facility's borrowing capacity has been increased from $2.75 billion to $3.50 billion and (ii) permit us to further increase the Supplemental Facility's borrowing capacity to $4.25 billion during its term.

            Simon has historically had access to public equity markets and the Operating Partnership has historically had access to private and public 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 Simon's status as a REIT require us to regularly access the debt markets to raise funds for acquisition, development and redevelopment activity, and to refinance maturing debt. Simon 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 Facilities and the Commercial Paper program to address our debt maturities and capital needs through 2016.

Cash Flows

            Our net cash flow from operating activities and distributions of capital from unconsolidated entities for the three months ended March 31, 2016 totaled $786.3 million. In addition, we had net proceeds from our debt financing and repayment activities of $162.8 million in 2016. These activities are further discussed below under "Financing and Debt." During the first three months of 2016, we also:

•

funded the acquisition of our portion of a joint venture interest, the aggregate cash portion of which was $38.3 million,

37

---

Table of Contents

•

paid stockholder dividends and unitholder distributions totaling $580.3 million and preferred unit distributions totaling $1.3 million,



•

funded consolidated capital expenditures of $189.0 million (including development and other costs of $34.7 million, redevelopment and expansion costs of $112.8 million, and tenant costs and other operational capital expenditures of $41.5 million), and



•

funded investments in unconsolidated entities of $104.5 million.

            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 and/or distributions to partners necessary to maintain Simon's 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 the 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 2016, 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 the Credit Facilities, curtail planned capital expenditures, or seek other additional sources of financing as discussed above.

Financing and Debt

Unsecured Debt

            At March 31, 2016, our unsecured debt consisted of $14.8 billion of senior unsecured notes of the Operating Partnership, net of discounts, $634.7 million outstanding under the $4.0 billion Credit Facility, $50.0 million outstanding under the Supplemental Facility, and $975.4 million outstanding under the Commercial Paper program. The March 31, 2016 balance on the Credit Facility included $246.5 million (U.S. dollar equivalent) of Euro-denominated borrowings and $198.1 million (U.S. dollar equivalent) of Yen-denominated borrowings. At March 31, 2016, the outstanding amount under the Commercial Paper program was $975.4 million, of which $195.0 million was related to U.S. dollar equivalent of Euro-denominated notes. Foreign currency denominated borrowings under both the Credit Facility and the Commercial Paper program are designated as net investment hedges of a portion of our international investments.

            On March 31, 2016, we had an aggregate available borrowing capacity of $5.1 billion under the Credit Facilities. The maximum aggregate outstanding balance under the Credit Facilities during the three months ended March 31, 2016 was $1.2 billion and the weighted average outstanding balance was $568.8 million. Letters of credit of $6.8 million were outstanding under the Credit Facilities as of March 31, 2016.

            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, subject to our continued compliance with the terms thereof. The base interest rate on the Credit Facility is LIBOR plus 80 basis points with an additional facility fee of 10 basis points.

            On April 6, 2016, the Operating Partnership amended the Supplemental Facility to, among other matters, (i) exercise its $750.0 million accordion feature such that the Supplemental Facility's borrowing capacity has been increased from $2.75 billion to $3.50 billion and (ii) permit us to further increase the Supplemental Facility's borrowing capacity to $4.25 billion during its term. The initial maturity date of the Supplemental Facility is June 30, 2019 and can be extended for an additional year to June 30, 2020 at our sole option, subject to our continued compliance with the terms thereof. The base interest rate on the Supplemental Facility is LIBOR plus 80 basis points with an additional facility fee of 10 basis points. The Supplemental Facility provides for borrowings denominated in U.S. dollars, Euro, Yen, Sterling, Canadian dollars and Australian dollars.

Table of Contents

            The maximum aggregate program size of the Commercial Paper program is $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. The Commercial Paper program is supported by the Credit Facilities and, if necessary or appropriate, we may make one or more draws under either the Credit Facility or the Supplemental Facility to pay amounts outstanding from time to time on the Commercial Paper program. On March 31, 2016, we had $975.4 million outstanding under the Commercial Paper program, comprised of $780.4 million outstanding in U.S. dollar denominated notes and $195.0 million (U.S. dollar equivalent) of Euro denominated notes with weighted average interest rates of 0.53% and 0.02%, respectively. The borrowings mature on various dates from June 10, 2016 to June 24, 2016 and reduce amounts otherwise available under the Credit Facilities.

            On January 13, 2016, the Operating Partnership issued $550.0 million of senior unsecured notes at a fixed interest rate of 2.50% with a maturity date of July 15, 2021 and $800.0 million of senior unsecured notes at a fixed interest rate of 3.30% with a maturity date of January 15, 2026. Proceeds from the unsecured notes offering were used to pay down the Credit Facility, unencumber three properties and redeem senior unsecured notes at par in February 2016.

            During the three months ended March 31, 2016, the Operating Partnership redeemed at par $163.3 million of senior unsecured notes with a fixed interest rate of 6.10%.

Mortgage Debt

            Total mortgage indebtedness was $6.6 billion at March 31, 2016 and December 31, 2015.

            During the three months ended March 31, 2016, we repaid $373.1 million in mortgage loans, with a weighted average interest rate of 8.00%, unencumbering three properties.

            On January 1, 2016, as discussed in Note 5, we consolidated the European entity that held our interests in six Designer Outlet properties, as we obtained control of the entity. This resulted in the consolidation of two of the six operating properties — Parndorf Designer Outlet and Roermond Designer Outlet, subject to existing fixed rate mortgage loans of $104.3 million and $204.0 million, respectively, (both amounts U.S. dollar equivalent). The loans mature on May 20, 2022 and December 1, 2021 and bear interest at 1.95% and 1.86%, respectively.

Covenants

            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 March 31, 2016, we were in compliance with all covenants of our unsecured debt.

            At March 31, 2016, we are the borrowers under 45 non-recourse mortgage notes secured by mortgages on 48 properties, including two separate pools of cross-defaulted and cross-collateralized mortgages encumbering a total of five 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 that serve as collateral for that debt. If the applicable borrower under these non-recourse mortgage covenants fails to comply with these covenants, the lender could accelerate the debt and enforce its right against their collateral. At March 31, 2016, 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, liquidity or results of operations.

Summary of Financing

            Our consolidated debt, adjusted to reflect outstanding derivative instruments, and the effective weighted average interest rates as of March 31, 2016 and December 31, 2015, 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 the separate 2015 Annual Reports on Form 10-K of Simon and the Operating Partnership.

            In regards to long-term debt arrangements, the following table summarizes the material aspects of these future obligations on our consolidated indebtedness as of March 31, 2016, for the remainder of 2016 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 our 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 March 31, 2016, the Operating Partnership guaranteed joint venture-related mortgage indebtedness of $308.8 million (of which we have a right of recovery from our joint venture partners of $76.5 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'/unitholders' 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.

Table of Contents

            In February 2016, we and our partner, through our European investee, acquired a noncontrolling 75.0% ownership interest in an outlet center in Ochtrup, Germany for cash consideration of approximately $38.3 million.

            On April 14, 2016, we and our joint venture partner, Invesco Real Estate, acquired The Shops at Crystals, a 324,000 sf luxury retail property located at the entryway of CityCenter in Las Vegas, Nevada, for an acquisition price of approximately $1.1 billion. We have a 50% noncontrolling interest in this venture.

            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 January of 2016, we disposed of our interests in two multi-family residential investments and a consolidated retail property. Our share of the gross proceeds from these transactions was $72.4 million. The gain on the consolidated retail property was $10.6 million. The aggregate gain of $36.9 million from the sale of the two residential investments is included in other income and resulted in an additional $7.2 million in taxes included in income and other taxes.

Joint Venture Formation Activity

            On April 13, 2015, we announced a joint venture with Sears Holdings, or Sears, whereby Sears contributed 10 of its properties located at our malls to the joint venture in exchange for a 50% noncontrolling interest in the joint venture. We contributed $114.0 million in cash in exchange for a 50% noncontrolling interest in the 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 for any recaptured space. On July 7, 2015, we separately invested approximately $33.0 million in exchange for 1,125,760 common shares of Seritage Growth Properties, or Seritage, a public REIT formed by Sears, which we account for as an available-for-sale security. Seritage now holds Sears' interest in the joint venture.

            On July 22, 2015, we closed on our previously announced joint venture with HBC, to which HBC contributed 42 properties in the U.S. and we committed to contribute $100.0 million for improvements to the properties contributed by HBC in exchange for a noncontrolling equity interest in HBS. As of March 31, 2016, we have funded $5.7 million of this commitment. On September 30, 2015, HBC announced it had closed on the acquisition of Galeria Holding, the parent company of Germany's leading department store, Kaufhof. In conjunction with the closing, HBS acquired 41 Kaufhof properties in Germany from HBC. All of the properties have been leased to affiliates of HBC. We contributed an additional $178.5 million to HBS upon closing of the Galeria Holding transaction. Our noncontrolling equity interest in HBS is approximately 9.2% at March 31, 2016.

Development Activity

            New Domestic Developments, Redevelopments and Expansions.    During 2015, construction began on the following properties:

•

A 355,000 square foot upscale outlet center located in Columbus, Ohio, which is scheduled to open in June 2016. We own a 50% noncontrolling interest in this project. Our estimated share of the cost of this project is $47.5 million.



•

Clarksburg Premium Outlets, a 392,000 square foot project, located in Clarksburg, Maryland, which is scheduled to open in October 2016. We own a 66% noncontrolling interest in this project. Our estimated share of the cost of this project is $127.7 million.



•

The Shops at Clearfork, a 545,000 square foot project located in Fort Worth, Texas, which is scheduled to open in February 2017. We own a 45% noncontrolling interest in this project. Our estimated share of the cost of this project is $101.6 million.



•

The 500,000 square foot retail component of Brickell City Centre, a mixed-use development in downtown Miami. We own a 25% noncontrolling interest in the retail component of this project which is scheduled to open in the Fall of 2016. Our share of the estimated cost of this project including development fees is approximately $110.0 million.

            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 over 33 properties in the United States.

41

---

Table of Contents

            Our share of the costs of all new development, redevelopment and expansion projects currently under construction is approximately $2.0 billion. We expect to fund these capital projects with cash flows from operations. We seek a stabilized return on invested capital in the range of 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 2016 will be approximately $159 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 March 31, 2016 (in millions):

Dividends, Distributions and Stock Repurchase Program

            Simon paid a common stock dividend of $1.60 per share, and the Operating Partnership made a distribution of $1.60 per unit, in the first quarter of 2016. Simon's Board of Directors declared a quarterly cash dividend for the second quarter of 2016 of $1.60 per share of common stock payable on May 31, 2016 to stockholders of record on May 17, 2016. The distribution rate on units is equal to the dividend rate on common stock. In order to maintain its status as a REIT, Simon must pay a minimum amount of dividends. Simon's future dividends and the Operating Partnership's future distributions will be determined by Simon's Board of Directors, in its sole discretion, based on actual and projected financial condition, liquidity and results of operations, cash available for dividends and limited partner distributions, cash reserves as deemed necessary for capital and operating expenditures, financing covenants, if any, and the amount required to maintain Simon's status as a REIT.

            On April 2, 2015, Simon's Board of Directors authorized Simon to repurchase up to $2.0 billion of common stock over a twenty-four month period as market conditions warrant. Simon may repurchase the shares in the open market or in privately negotiated transactions. During the first quarter of 2016, no purchases were made as part of this program. As Simon repurchases shares under this program, the Operating Partnership repurchases an equal number of our units from Simon.

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, 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 or outlook, 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 Simon's status as a REIT. We discussed these and other risks and uncertainties under the heading "Risk Factors" in our separate 2015 Annual Reports on Form 10-K of Simon and the Operating Partnership. We may update that discussion in subsequent periodic reports, but 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, Portfolio NOI and comparable property NOI. We believe that these non-GAAP measures are helpful to investors because they are widely recognized measures of the performance of REITs and provide a relevant basis for comparison among REITs. We also use these measures internally to measure the operating performance of our portfolio.

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

•

excluding real estate related depreciation and amortization,



•

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



•

excluding gains and losses from the sales 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. 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:

•

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.    Qualitative and Quantitative Disclosures About Market Risk

            Sensitivity Analysis.    We disclosed a qualitative and quantitative analysis regarding market risk in Management's Discussion and Analysis of Financial Condition and Results of Operations included in the separate 2015 Annual Reports on Form 10-K of Simon and the Operating Partnership. There have been no material changes in the assumptions used or results obtained regarding market risk since December 31, 2015.

Item 4.    Controls and Procedures

Simon

            Evaluation of Disclosure Controls and Procedures.    Simon maintains disclosure controls and procedures (as defined in Rule 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 Simon files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's, or the SEC's, rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosures. Because of inherent limitations, disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable, and not absolute, assurance that the objectives of disclosure controls and procedures are met.

            Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of Simon's disclosure controls and procedures as of March 31, 2016. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2016, Simon's disclosure controls and procedures were effective at a reasonable assurance level.

            Changes in Internal Control Over Financial Reporting.    There have not been any changes in Simon's internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2016 that have materially affected, or are reasonably likely to materially affect, Simon's internal control over financial reporting.

The Operating Partnership

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

            Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of the Operating Partnership's disclosure controls and procedures as of March 31, 2016. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of March 31, 2016, the Operating Partnership's disclosure controls and procedures were effective at a reasonable assurance level.

            Changes in Internal Control Over Financial Reporting.    There have not been any changes in the Operating Partnership's internal control over financial reporting (as defined in Rule 13a-15(f) under the Exchange Act) that occurred during the quarter ended March 31, 2016 that have materially affected, or are reasonably likely to materially affect, the Operating Partnership's internal control over financial reporting.
