1.                 Organization

Simon Property Group, L.P., a Delaware limited partnership (the “Operating Partnership”), is a majority owned subsidiary of Simon Property Group, Inc., a Delaware corporation (“Simon Property”). Simon Property is a self-administered and self-managed real estate investment trust (“REIT”) under the Internal Revenue Code of 1986, as amended (the “Code”). In these condensed notes to the unaudited consolidated financial statements, the terms “we”, “us” and “our” refer to the Operating Partnership and its subsidiaries.

We are engaged primarily in the ownership, development, and management of retail real estate, primarily regional malls, Premium Outlet® centers and community/lifestyle centers. As of March 31, 2007, excluding assets acquired in the transaction with The Mills Corporation (“Mills”) as described below, we owned or held an interest in 285 income-producing properties in the United States, which consisted of 171 regional malls, 68 community/lifestyle centers, 36 Premium Outlet centers and 10 other shopping centers or outlet centers in 38 states and Puerto Rico (collectively, the “Properties”, and individually, a “Property”). We also own interests in four parcels of land held in the United States for future development (together with the Properties, the “Portfolio”). Internationally, we have ownership interests in 53 European shopping centers (France, Italy and Poland); five Premium Outlet centers in Japan; and one Premium Outlet center in Mexico. We also have begun construction on a Premium Outlet center in South Korea and, through a joint venture arrangement we have ownership interests in four shopping centers under construction in China. Additionally, on March 29, 2007, SPG-FCM Ventures, LLC (“SPG-FCM”), a joint venture between an entity owned 50% by the Operating Partnership and 50% by funds managed by Farallon Capital Management, L.L.C. (“Farallon”), successfully completed a tender offer to acquire all of the outstanding common stock of The Mills Corporation. As of the end of March 31, 2007, SPG-FCM owned 75.38% of the outstanding common stock of Mills. As a result, we now hold an interest in an additional 38 properties located throughout the United States, including 18 regional malls, 3 community/lifestyle centers, and 17 other retail properties which will be referred to as The Mills. Mills was also a partner in two assets in which we already held an ownership interest.

2.                 Basis of Presentation

The accompanying unaudited consolidated financial statements include the accounts of the Operating Partnership and its subsidiaries, and all significant inter-company amounts have been eliminated. Due to the seasonal nature of certain operational activities, the results for the interim period ended March 31, 2007 are not necessarily indicative of the results that may be obtained for the full fiscal year.

These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and include all of the information and disclosures required by accounting principles generally accepted in the United States (GAAP) for interim reporting. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments necessary for fair presentation (including normal recurring accruals) have been included. The consolidated financial statements in this Form 10-Q should be read in conjunction with the audited consolidated financial statements and related notes contained in our 2006 Annual Report on Form 10-K.

As of March 31, 2007, excluding assets acquired in the transaction with Mills as described above, of our 344 properties we consolidated 200 wholly-owned properties and 19 additional properties that are less than wholly-owned, but which we control or for which we are the primary beneficiary. We account for the

6

remaining 125 properties using the equity method of accounting (joint venture properties). We manage the day-to-day operations of 56 of the 125 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. Additionally, our investment in SPG-FCM, which holds an interest in Mills, and as a result the additional 38 properties acquired in its acquisition of Mills, is also accounted for by us under the equity method of accounting. We have determined that SPG-FCM is not a variable interest entity (VIE) and Farallon has substantive participating rights with respect to the assets and operations of SPG-FCM pursuant to the applicable partnership agreements.

We allocate our net operating results after preferred distributions based on our partners’ respective weighted average ownership. In addition, Simon Property owns certain of our preferred units. Simon Property’s weighted average ownership interest in us was 79.2% and 79.0% for the three months ended March 31, 2007 and 2006, respectively. As of March 31, 2007 and December 31, 2006, Simon Property’s ownership interest in us was 79.4% and 78.9%, respectively. We adjust the limited partners’ interest at the end of each period to reflect their respective ownership interest in the Operating Partnership.

Preferred distributions in the accompanying statements of operations and cash flows represent distributions on outstanding preferred units of limited partnership interest.

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 market value. Cash equivalents generally consist of commercial paper, bankers acceptances, Eurodollars, repurchase agreements, and money markets. Cash and cash equivalents, as of March 31, 2007, includes a balance of $33.0 million related to these gift card programs which we do not consider available for general working capital purposes.

4.                 Per Unit Data

We determine basic earnings per unit based on the weighted average number of common units outstanding during the period. We determine diluted earnings per unit based on the weighted average number of common units outstanding combined with the incremental weighted average units that would have been outstanding assuming all dilutive potential common units were converted into units at the earliest date possible. The following table sets forth the computation of our basic and diluted earnings per unit.

For the three months ended March 31, 2007, potentially dilutive securities include stock options of Simon Property and certain preferred units which are exchangeable for common units. The only potentially dilutive security that had a dilutive effect for the three months ended March 31, 2007 and 2006 were stock

7

options of Simon Property. Common units may be exchanged for shares of Simon Property common stock, on a one-for one basis, in certain circumstances. We accrue distributions when they are declared.

5.                 Investment in Unconsolidated Entities

Real Estate Joint Ventures

Joint ventures are common in the real estate industry. We use joint ventures to finance properties, develop new properties, and diversify our risk in a particular property or portfolio. Excluding assets acquired in the transaction with Mills as described above, we held joint venture ownership interests in 66 Properties in the United States as of March 31, 2007 and 68 as of December 31, 2006. We also held interests in two joint ventures which owned 53 European shopping centers as of March 31, 2007 and December 31, 2006. We also held an interest in five joint venture properties under operation in Japan and one joint venture property in Mexico. We account for these Properties using the equity method of accounting.

Substantially all of our joint venture Properties are subject to rights of first refusal, buy-sell provisions, or other sale or marketing rights for partners which are customary in real estate joint venture agreements and the industry. Our partners in these joint ventures may initiate these provisions at any time (subject to any applicable lock up or similar restrictions), which could result in either the sale of our interest or the use of available cash or borrowings to acquire a joint venture interest from our partner.

Acquisition of The Mills Corporation by SPG-FCM

On February 16, 2007, SPG-FCM entered into a definitive merger agreement with Mills to acquire all of the outstanding common stock of Mills for $25.25 per common share in cash. The acquisition was completed through a cash tender, which concluded on March 29, 2007. As of March 31, 2007 we and Farallon had each funded $475 million into SPG-FCM to acquire the shares that were submitted for tender as of March 29, 2007, representing 75.38% of the outstanding shares of common stock of Mills. In connection with the closing of the tender offer, we also loaned $286 million through three separate one-year note payable arrangements to SPG-FCM that bear interest at rates ranging from LIBOR plus 37.5 basis points to LIBOR plus 270 basis points. The $286 million in notes receivable from SPG-FCM are reported with notes receivable from related parties on the consolidated balance sheet. We expect these notes will be repaid by SPG-FCM at par during the second quarter of 2007 from the proceeds of refinancing activity.

In connection with the execution of a definitive merger agreement with Mills, we made a loan to Mills on February 16, 2007 to permit it to repay an existing loan facility. The $1.187 billion loan to Mills carries a rate of LIBOR plus 270 basis points and payment is due in full one year from issuance. The loan facility also permits Mills to borrow an additional $365 million on a revolving basis for working capital requirements and general corporate purposes. We received a financing fee of $15 million at the closing of loan which is being amortized into other income over the one-year term of the loan. No borrowings under the revolving portion of this arrangement had been drawn as of the end of the first quarter of 2007.

On April 3, 2007, the merger of a subsidiary of SPG-FCM and Mills was completed. On April 18, 2007, a subsidiary of SPG-FCM was merged into Mills’ operating partnership (“Mills LP”) was completed. The common unitholders in the Mills LP will receive $25.25 per unit in cash, subject to certain qualified unitholders having the option to exchange their units for limited partnership units of the Operating Partnership based on a fixed exchange ratio of 0.211 Operating Partnership units for each limited partnership unit in the Mills LP. As a result of the change in control of Mills, holders of Mills’ $316.3 million in Series F Convertible Cumulative Redeemable Preferred Stock have the right to require that Mills repurchase their shares for cash equal to the liquidation preference per share plus accrued and unpaid

8

dividends. If all of the holders of Mills’ Series F preferred stock exercise this right, Mills will be required to pay approximately $333 million.

We have and intend to obtain all funds necessary to fulfill our equity requirement to SPG-FCM, as well as any funds that we have or will provide in the form of loans to Mills or SPG-FCM, from available cash and our Credit Facility. Beginning in the second quarter of 2007, Simon Property or an affiliate will also begin to serve as the manager for substantially all of the additional 38 properties in which SPG-FCM holds an interest. As a result of this acquisition, we now hold a controlling interest in two properties where we previously held a 50% ownership interest (Town Center at Cobb and Gwinnett Place) and as a result we consolidated these two properties at the date of acquisition.

SPG-FCM is in the process of performing the necessary purchase price allocations for its acquisition of Mills. The valuations will be developed with the assistance of a third-party professional appraisal firm. The acquisition of Mills by SPG-FCM will involve the assumption of $954.9 million of preferred stock and a proportionate share of property-level mortgage debt, SPG-FCM’s share of which approximates $4 billion, both of which are exclusive of any fair market value adjustments which will be included in SPG-FCM’s preliminary purchase accounting allocations to be finalized during the second quarter of 2007.

International Joint Venture Investments

We conduct our international operations in Europe through our two European joint venture investment entities; Simon Ivanhoe S.à.r.l. (“Simon Ivanhoe”), and Gallerie Commerciali Italia (“GCI”). The carrying amount of our total combined investment in these two joint venture investments is $339.0 million and $338.1 million as of March 31, 2007 and December 31, 2006, respectively, net of the related cumulative translation adjustments. The Operating Partnership has a 50% ownership in Simon Ivanhoe and a 49% ownership in GCI as of March 31, 2007.

We conduct our international Premium Outlet operations in Japan through joint venture partnerships with Mitsubishi Estate Co., Ltd. and Sojitz Corporation (formerly known as Nissho Iwai Corporation). The carrying amount of our investment in these Premium Outlet joint ventures in Japan is $279.3 million and $281.2 million as of March 31, 2007 and December 31, 2006, respectively, net of the related cumulative translation adjustments. We have a 40% ownership in these Japan Premium Outlet joint ventures. As of March 31, 2007, we held a 50% ownership interest in a Premium Outlet in South Korea which is now substantially complete, for which our investment approximated $19.2 million.

During 2006, we finalized the formation of joint venture arrangements to develop and operate shopping centers in China. The shopping centers will be anchored by Wal-Mart stores and will be through a 32.5% ownership in a joint venture entity, Great Mall Investments, Ltd. (“GMI”). We are planning on initially developing five centers, four of which are currently under construction, with our share of the total equity commitment of approximately $49.5 million. We account for our investments in GMI under the equity method of accounting. As of March 31, 2007, our combined investment in these shopping centers in GMI is approximately $17.5 million.

Summary Financial Information

Summary financial information of all of our joint ventures, excluding that of SPG-FCM, and a summary of our investment in and share of income from such joint ventures follow. We condensed into separate line items major captions of the statements of operations for joint venture interests sold or consolidated. Consolidation occurs when we acquire an additional interest in the joint venture and, as a result, gain unilateral control of the Property or are determined to be the primary beneficiary. We reclassify these line items into “Discontinued Joint Venture Interests” and “Consolidated Joint Venture Interests” on the balance sheets and statements of operations, if material, so that we may present comparative results of operations for those joint venture interests held as of March 31, 2007.

10

“Excess Investment” represents the unamortized difference of our investment over our share of the equity in the underlying net assets of the joint ventures acquired. We amortize excess investment over the life of the related Properties, typically no greater than 40 years, and the amortization is included in the reported amount of income from unconsolidated entities. We have presented our investment in SPG-FCM as a single line item due to the recent acquisition of Mills as this amount will be affected by our preliminary purchase price allocations which as discussed in note 2 are currently underway. We intend to present the assets and liabilities of SPG-FCM included within this Summary Financial Information at the end of our second quarter.

6.                 Debt

Unsecured Debt

Credit Facility.   Significant draws on the Credit Facility during the three months ended March 31, 2007 were as follows:

Other amounts drawn on the Credit Facility were primarily for general working capital purposes. We repaid a total of $170.0 million on the Credit Facility during the three months ended March 31, 2007. The total outstanding balance on the Credit Facility as of March 31, 2007 was $1.8 billion, and the maximum amount outstanding during the quarter was approximately $2.0 billion. During the first three months of 2007, the weighted average outstanding balance on the Credit Facility was approximately $741.0 million.

Secured Debt

Total secured indebtedness was $4.6 billion and $4.4 billion at March 31, 2007 and December 31, 2006, respectively. During the three months ended March 31, 2007, we repaid $122.4 million in mortgage loans, unencumbering two properties.

As a result of the acquisition of Mills by SPG-FCM, as of March 31, 2007, we now hold a controlling ownership interest in Gwinnett Place and Town Center at Cobb, and as a result they were consolidated as of the acquisition date. This included the consolidation of two mortgages secured by Gwinnett Place of $35.6 million and $79.2 million at fixed rates of 7.54% and 7.25%, respectively, and two mortgages secured by Town Center at Cobb of $45.4 million and $60.3 million at fixed rates of 7.54% and 7.25%, respectively.

7.                 Partners’ Equity

Under The Simon Property Group 1998 Stock Incentive Plan, on February 26, 2007, the Compensation Committee of Simon Property’s Board of Directors, under The Simon Property Group 1998 Stock Incentive Plan, awarded 246,271 restricted shares of Simon Property common stock to employees under this Plan at a fair value of $115.62 per share. The fair market value of the restricted stock awarded on February 26, 2007 has been deferred and is being amortized over a four-year vesting service period. As a result of the award of restricted stock, we issued a like number of units to Simon Property in accordance with our partnership agreement.

During the first three months of 2007, nine limited partners exchanged 1,692,474 units for a like number of shares of common stock of Simon Property, increasing Simon Property’s interest in us.

On May 11, 2006, the Simon Property Board of Directors authorized a common stock repurchase program under which Simon Property may purchase up to 6,000,000 shares of its common stock subject to a maximum aggregate purchase price of $250 million over the next twelve months as market conditions warrant. Simon Property may purchase the shares in the open market or in privately negotiated transactions. There have been no purchases under this program in 2007.

As previously disclosed, for the quarter ending March 31, 2007, holders of Series I 6% Convertible Perpetual Units (“Series I Preferred Units”) and Simon Property’s Series I 6% Convertible Perpetual Preferred Stock (“Series I Preferred Stock”) could elect to convert their securities during the quarter into common units of the Operating Partnership and shares of Simon Property common stock, respectively.

12

The optional conversion is as a result of the closing sale price of Simon Property’s common stock exceeding the applicable trigger price per share for a period of 20 trading days in the last 30 trading days of the prior quarter. If holders of a Series I Preferred Unit convert into common units, then the holder may also elect to convert those units into common stock on a one-for-one basis in accordance with our partnership agreement. During the three months ended March 31, 2007, 6,461 shares of Series I Preferred Stock were converted into 5,075 shares of Simon Property common stock and Simon Property converted a like number of its Series I Preferred Units into common units. As of March 31, 2007, the conversion trigger price of $79.16 had been met and the Series I Preferred Units are convertible into 0.78957 of a common unit and the Series I Preferred Stock is convertible into 0.78957 of a share of Simon Property common stock beginning April 2, 2007 through June 29, 2007.

Preferred units whose redemption is outside of our control have been classified as temporary equity in the accompanying balance sheets.

8.                 Commitments and Contingencies

Litigation

There have been no material developments with respect to the pending litigation disclosed in our 2006 Annual Report on Form 10-K.

We are involved in various other legal proceedings that arise in the ordinary course of our business. We believe that such routine litigation, claims and administrative proceedings will not have a material adverse impact on our financial position or our results of operations. We record a liability when a loss is considered probable and the amount can be reasonably estimated.

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, 2007, we have loan guarantees and other guarantee obligations of $79.6 million and $23.2 million, respectively, to support our total $3.4 billion share of joint venture mortgage and other indebtedness in the event that the joint venture partnership defaults under the terms of the underlying arrangement. Mortgages which are guaranteed by us are secured by the property of the joint venture and that property could be sold in order to satisfy the outstanding obligation.

9.                 Real Estate Acquisitions and Dispositions

On March 1, 2007, we acquired the additional 40% interest in both University Park Mall and University Center located in Mishawaka, IN from our partner and as a result, we now own 100% of University Park Mall, a regional mall Property, and University Center, a community/lifestyle center Property. On March 28, 2007, we acquired The Maine Outlet, a 112,000 square foot outlet center located in Kittery, Maine, adjacent to our Kittery Premium Outlets Property.

We had no consolidated property dispositions during the three months ended March 31, 2007.

10.          Recent Financial Accounting Standards

On January 1, 2007, we adopted FASB Interpretation No. 48, “Accounting for Uncertainty in Income Taxes, an Interpretation of FASB Statement No. 109” (“FIN 48”). FIN 48 clarifies the accounting for uncertainty in income taxes recognized in a company’s financial statements and prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return. The Interpretation also provides guidance on description, classification, interest and penalties, accounting in interim periods, disclosure and transition. The adoption of FIN 48 did not have any impact on our financial position or results of operations.

13

In September 2006, the FASB issued FASB No. 157, “Fair Value Measurements”. SFAS 157 is definitional and disclosure oriented and addresses how companies should approach measuring fair value when required by GAAP; it does not create or modify any current GAAP requirements to apply fair value accounting. The Standard provides a single definition for fair value that is to be applied consistently for all accounting applications, and also generally describes and prioritizes according to reliability the methods and inputs used in valuations. SFAS 157 prescribes various disclosures about financial statement categories and amounts which are measured at fair value, if such disclosures are not already specified elsewhere in GAAP. The new measurement and disclosure requirements of SFAS 157 are effective for us in the first quarter of 2008. We do not expect the adoption of SFAS 157 will have a significant impact on our results of operations or financial position.

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

You should read the following discussion in conjunction with the financial statements and notes thereto that are included in this report. Certain statements made in this section or elsewhere in this report may be deemed “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Although we believe the expectations reflected in any forward-looking statements are based on reasonable assumptions, we can give no assurance that our expectations will be attained, and it is possible that our actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks and uncertainties. Those risks and uncertainties include, but are not limited to: our ability to meet debt service requirements, the availability of financing, changes in our credit rating, changes in market rates of interest and foreign exchange rates for foreign currencies, the ability to hedge interest rate risk, risks associated with the acquisition, development and expansion of properties, general risks related to retail real estate, the liquidity of real estate investments, environmental liabilities, international, national, regional and local economic climates, changes in market rental rates, trends in the retail industry, relationships with anchor tenants, the inability to collect rent due to the bankruptcy or insolvency of tenants or otherwise, risks relating to joint venture properties, costs of common area maintenance, competitive market forces, risks related to international activities, insurance costs and coverage, impact of terrorist activities, inflation and maintenance of REIT status. We discussed these and other risks and uncertainties under the heading “Risk Factors” in our annual and quarterly periodic reports filed with the SEC that could cause our actual results to differ materially from the forward-looking statements that we make. We may update that discussion in our periodic reports, but otherwise we undertake no duty or obligation to update or revise these forward-looking statements, whether as a result of new information, future developments, or otherwise.

Overview

Simon Property Group, L.P., a Delaware limited partnership (the “Operating Partnership”), is a majority owned subsidiary of Simon Property Group, Inc., a Delaware corporation (“Simon Property”). Simon Property is our general partner and a self-administered and self-managed real estate investment trust. In this discussion, the terms the “we”, “us” and “our” refer to the Operating Partnership and its subsidiaries.

We are engaged in the ownership, development, and management of retail real estate properties, primarily regional malls, Premium Outlet® centers and community/lifestyle centers. As of March 31, 2007, excluding assets acquired in the transaction with The Mills Corporation (“Mills”) as described below, we owned or held an interest in 285 income-producing properties in the United States, which consisted of 171 regional malls, 68 community/lifestyle centers, 36 Premium Outlet centers and 10 other shopping centers or outlet centers in 38 states plus Puerto Rico (collectively, the “Properties”, and individually, a “Property”). We also own interests in four parcels of land held in the United States for future development (together with the Properties, the “Portfolio”). In the United States, we have six new properties currently under development aggregating approximately 3.2 million square feet which will open during 2007 or early

14

2008. Internationally, we have ownership interests in 53 European shopping centers (France, Italy and Poland); five Premium Outlet centers in Japan; and one Premium Outlet center in Mexico. We also have begun construction on a Premium Outlet center in which we will hold a 50% interest located in South Korea and, through a joint venture arrangement, we will have a 32.5% interest in five shopping centers (four of which are under construction) in China. Additionally, on March 29, 2007, SPG-FCM Ventures, LLC (“SPG-FCM”), a joint venture between an entity owned 50% by the Operating Partnership and 50% by funds managed by Farallon Capital Management, L.L.C. (“Farallon”), successfully completed a tender offer to acquire all of the outstanding common stock of The Mills Corporation (“Mills”). As a result, we now hold an interest in an additional 38 properties owned by Mills located throughout the United States, including 18 regional malls, 3 community/lifestyle centers, and 17 other retail properties which will be referred to hereafter as The Mills.

Operating Fundamentals

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

·       Base minimum rents and cart and kiosk rentals,

·       Overage and percentage rents based on tenants’ sales volume, and

·       Recoveries of a significant portion of our operating expenses, including common area maintenance, real estate taxes, and insurance.

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 seek growth in our earnings and cash flows by enhancing the profitability and operation of our properties and investments. We seek to accomplish this growth through the following:

·       Focusing on leasing to increase revenues and utilization of economies of scale to reduce operating expenses,

·       Expanding and re-tenanting existing franchise locations at competitive market rates,

·       Adding mixed-use elements to our Portfolio through our asset intensification initiatives. This may include adding elements such as multifamily, condominiums, hotel and self-storage at selected locations,

·       The acquisition of high quality real estate assets or portfolios of assets, and

·       Selling non-core assets.

We also grow by generating supplemental revenues in our existing real estate portfolio, from outlot parcel sales and, due to our size and tenant relationships, from the following:

·       Simon Brand Ventures (“Simon Brand”) mall marketing initiatives revenue sources which include: payment systems (including marketing fees relating to the sales of bank-issued prepaid cards), national marketing alliances, static and digital media initiatives, business development, sponsorship, and other events.

·       Simon Business Network (“Simon Business”) offers property operating services to our tenants and others resulting from its relationships with vendors.

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

15

We routinely review and evaluate acquisition opportunities based on their complement to our Portfolio. Lastly, we are selectively expanding our international presence. 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 overall growth goals, 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.

·       Manage our overall financial structure in a fashion that preserves our investment grade ratings.

Results Overview

Diluted earnings per unit decreased $0.03 during the first three months of 2007, or 6.4%, to $0.44 from $0.47 for the same period last year. The 2006 results include a $34.4 million gain (or $0.12 per diluted unit) from the sale of partnership interests in one of our European joint ventures to our new partner, Ivanhoe Cambridge, Inc. (“Ivanhoe”), an affiliate of Caisse de dépôt et placement du Québec, and recognition of $10.2 million in income (or $0.03 per diluted unit) from contributed beneficial interests, representing the right to receive cash flow, capital distributions, and related profits and losses in a regional mall entity. Included in the first quarter of 2007 was the receipt of $19.0 million of lease settlements from anchor store activity and $11.9 million of interest income attributable to a mezzanine loan made to Mills prior to SPG-FCM acquiring a controlling portion of the common shares of Mills on March 29, 2007. The remaining portion of the activity that offset the items occurring in the first quarter of 2006 was driven by strong core operations as further described below.

Our core business fundamentals remained strong during the first three months of 2007. Regional mall comparable sales per square foot (“psf”) strengthened during the first three months of 2007, increasing 5.6% to $487 psf from $461 psf for the same period in 2006 reflecting robust retail sales activity. Our regional mall average base rents increased 3.9% to $36.18 psf as of March 31, 2007 from $34.83 psf as of March 31, 2006. In addition, our regional mall leasing spreads were $7.99 psf as of March 31, 2007 representing a 21.3% increase over expiring rents, compared with recent year’s performance. The operating fundamentals of the Premium Outlet centers and community/lifestyle centers also contributed to the improved operating results for the nine month period as seen in the following section entitled Portfolio Data, with the Portfolio effectively fully occupied at 99.1% and leasing spreads at $6.60, or 29.2% above expiring rents. Finally, regional mall occupancy was 91.8% as of March 31, 2007 as compared to 91.6% as of March 31, 2006.

Regarding financing activities, despite the increasing interest rate environment resulting in an approximate 49 basis point increase in LIBOR (5.32% at March 31, 2007 versus 4.83% at March 31, 2006), our effective overall borrowing rate for the three months ended March 31, 2007 decreased two basis points as compared to the three months ended March 31, 2006. This was principally as a result of the issuance of fixed rate debt during 2006. Our financing activities for the three months ended March 31, 2007 are highlighted by the following:

·       We paid off two mortgages totaling $122.4 million that bore interest at fixed rates ranging from 7.65% to 7.85%.

·       Borrowings on the Credit Facility increased to approximately $1.8 billion during the three months ended March 31, 2007, principally as a result of funds required to effect the acquisition of Mills by SPG-FCM for our equity investments of $475 million and for loans to Mills and SPG-FCM totaling $1.473 billion.

16

·       As a result of the acquisition of Mills by SPG-FCM, at March 31, 2007, we now hold a controlling ownership interest in Gwinnett Place and Town Center at Cobb, and as a result we now consolidate these two Properties. Included in this consolidation are two mortgages secured by Gwinnett Place of $35.6 million and $79.2 million at fixed rates of 7.54% and 7.25%, respectively, and two mortgages secured by Town Center at Cobb of $45.4 million and $60.3 million at fixed rates of 7.54% and 7.25%, respectively.

United States Portfolio Data

The Portfolio data discussed in this overview includes the following key operating statistics: occupancy, average base rent per square foot, and comparable sales per square foot for our three domestic platforms. We include acquired Properties in this data beginning in the year of acquisition and remove properties sold in the year disposed. We do not include any Properties located outside of the United States. The following table sets forth these key operating statistics for:

·       Properties that are consolidated in our consolidated financial statements,

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

·       the foregoing two categories of Properties on a total Portfolio basis.

17

Domestic Property Data:

(1)          Percentages may not recalculate due to rounding.

Occupancy Levels and Average Base Rent Per Square Foot.   Occupancy and average base rent are based on mall and freestanding Gross Leaseable Area (“GLA”) owned by us (“Owned GLA”) in the regional malls, all tenants at the Premium Outlet centers, and all tenants at community/lifestyle centers. Our Portfolio has maintained stable occupancy and increased average base rents.

Comparable Sales Per Square Foot.   Comparable sales include total reported retail tenant sales at Owned GLA (for mall and freestanding stores with less than 10,000 square feet) in the regional malls and all reporting tenants at the Premium Outlet centers. 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.

International Property Data

The following key operating statistics are provided for our international properties, which are accounted for using the equity method of accounting.

19

In addition to the activity discussed in the Results Overview, the following acquisitions, dispositions, and openings affected our income from unconsolidated entities in the comparative periods:

·       On November 10, 2006 we opened Coconut Point, in Bonita Springs, Florida, a 1.2 million square foot, open-air shopping center complex with village, lakefront and community center areas.

For the purposes of the following comparison between the three months ended March 31, 2007 and 2006, the above transactions are referred to as the Property Transactions. In the following discussions of our results of operations, “comparable” refers to Properties open and operating throughout the periods in both 2007 and 2006.

We sold the following properties in 2006 on the indicated date. Due to the limited significance of these properties on our financial statements, we did not report these properties as discontinued operations.

Three Months Ended March 31, 2007 vs. Three Months Ended March 31, 2006

Minimum rents, excluding rents from our consolidated Simon Brand and Simon Business initiatives, increased $21.0 million during the period, of which the Property Transactions accounted for $13.0 million of the increase. Total amortization of the fair market value of in-place leases decreased minimum rents by $1.7 million over that of the first quarter of 2006. Comparable rents, excluding rents from Simon Brand and Simon Business, increased $8.0 million, or 1.7%. This was primarily due to the leasing of space at higher rents that resulted in an increase in minimum rents of $9.4 million. In addition, rents from carts, kiosks, and other temporary tenants increased comparable rents by $0.5 million.

Overage rents increased $1.8 million or 11.4%, reflecting the increases in tenants’ sales.

Tenant reimbursements, excluding Simon Business initiatives, increased $9.0 million, of which the Property Transactions accounted for $5.2 million. The remainder of the increase of $3.8 million, or 1.8%, was in comparable Properties and was due to inflationary increases in property operating costs.

Total other income, excluding Simon Brand and Simon Business initiatives, increased $30.9 million, and was principally the result of the following:

·       $16.8 million in increased interest income due to $11.9 million in interest income for the period as a result of the loan to Mills, combined with increased interest rates and excess cash we held in the first half of the quarter from our December 2006 senior notes offering;

·       $14.7 million in increased lease settlement income as a result of settlements received from two department anchor stores in 2007 as compared to our 2006 lease settlement income from certain non-anchor tenants;

20

·       $1.9 million in loan financing fee amortization related to the $1.187 billion loan to Mills made on February 16, 2007; and

·       offset by decreases of $2.5 million in other net activity during the comparable period of 2006 on comparable Properties.

Revenues from Simon Brand and Simon Business initiatives increased $1.0 million to $35.4 million from $34.4 million. The increase in revenues is primarily due to increased event and sponsorship income.

Property operating expenses increased $3.3 million, $0.7 million from comparable properties (representing an increase of 0.7%) principally as a result of inflationary increases. The remainder of the increase in property operating expenses was due to the effect of the Property Transactions.

Depreciation and amortization expense increased $5.8 million and is primarily a result of the Property Transactions.

Real estate taxes decreased $2.6 million from the prior period due principally to a 2006 $6.5 million multi-year assessment settlement at a Property, partially offset by increases in expenses at our other comparable properties of $2.3 million. The remainder of the increase in Real estate tax expense was due to the effect of the Property Transactions.

Repairs and maintenance increased $3.1 million due to heavier snow removal costs in 2007 than that of 2006.

Home office and regional costs increased $3.4 million due to increased personnel costs, which is primarily due to the effect of the increase in our stock price on our stock-based compensation programs.

Interest expense increased $18.4 million due principally to the following:

·       the additional borrowings to fund the mezzanine loan to Mills:

·       the impact of increases in our average borrowing rates for our variable rate debt; and

·       the impact of increased fixed rate debt of $3.3 billion, which are generally at higher rates than our variable rate debt, due to the issuances of unsecured notes in May, August, and December of 2006.

During the first quarter of 2006, we recognized the receipt of a beneficial interest in a regional mall entity, which represents the majority of the decrease in our income from unconsolidated entities, net in the consolidated financial statements. This beneficial interest was terminated in November 2006.

Gain on sales of assets and interests in unconsolidated entities decreased $34.4 million over the prior period due to the recording of a $34.4 million gain on the sale of 10.5% of our interests in Simon Ivanhoe B.V./S.à.r.l. (“Simon Ivanhoe”) in 2006.

Preferred unit requirement decreased $5.8 million as a result of the redemption of the Series F Preferred Units in the fourth quarter of 2006.

Liquidity and Capital Resources

Because we generate revenues primarily from long-term leases, our financing strategy relies primarily on long-term fixed rate debt. We manage our floating rate debt to be at or below 15–25% of total outstanding indebtedness by setting interest rates for each financing or refinancing based on current market conditions. Because of attractive fixed-rate debt opportunities in the past three years, floating rate debt currently comprises approximately 14% of our total consolidated debt. Most of our floating rate debt relates to borrowings made from our Credit Facility to consummate the acquisition of Mills. We also enter into interest rate protection agreements as appropriate to assist in managing our interest rate risk. We derive most of our liquidity from leases that generate positive net cash flow from operations and

21

distributions of capital from unconsolidated entities that totaled $1.1 billion during the first three months of 2007. In addition, our Credit Facility provides an alternative source of liquidity as our cash needs vary from time to time.

Our balance of cash and cash equivalents decreased $589.4 million during 2007 to $340.0 million as of March 31, 2007. The March 31, 2007 and December 31, 2006 balances include $33.0 million and $27.2, respectively, related to our co-branded gift card programs, which we do not consider available for general working capital purposes.

On March 31, 2007, our Credit Facility had available borrowing capacity of approximately $1.1 billion During the first three months of 2007, the maximum amount outstanding under the Credit Facility was $2.0 billion and the weighted average amount outstanding was $741.0 million. The weighted average interest rate was 4.92% for the period ended March 31, 2007.

We and Simon Property also have access to public equity and long term unsecured debt markets and access to private equity from institutional investors at the Property level.

Acquisition of The Mills Corporation by SPG-FCM

On February 16, 2007, SPG-FCM entered into a definitive merger agreement with Mills to acquire all of the outstanding common stock of Mills for $25.25 per common share in cash. The acquisition was completed through a cash tender, which concluded on March 29, 2007. As of March 31, 2007, we and Farallon had each funded $475 million into SPG-FCM to acquire the shares that were submitted for tender as of March 29, 2007, representing 75.38% of the outstanding shares of common stock of Mills. In connection with the closing of the tender offer, we also loaned $286 million through three separate one-year note payable arrangements to SPG-FCM that bear interest at rates ranging from LIBOR plus 37.5 basis points to LIBOR plus 270 basis points. The $286 million in notes receivable from SPG-FCM are reported with notes receivable from related parties on the consolidated balance sheet. We expect these notes will be repaid by SPG-FCM at par during the second quarter of 2007 from the proceeds of refinancing activity.

In connection with execution of a definitive merger agreement with Mills, we made a loan to Mills on February 16, 2007 to permit it to repay an existing loan facility. The $1.187 billion loan to Mills carries a rate of LIBOR plus 270 basis points and payment is due in full one year from issuance. The loan facility also permits Mills to borrow an additional $365 million on a revolving basis for working capital requirements and general corporate purposes. We received a financing fee of $15 million at the closing of loan which is being amortized into other income over the one-year term of the loan. No borrowings under the revolving portion of this arrangement had been drawn as of the end of the first quarter of 2007.

On April 3, 2007, the merger of a subsidiary of SPG-FCM and Mills was completed. On April 18, 2007, a subsidiary of SPG-FCM was merged into Mills’ operating partnership (“Mills LP”) was completed. The common unitholders in the Mills LP will receive $25.25 per unit in cash, subject to certain qualified unitholders having the option to exchange their units for limited partnership units of the Operating Partnership based on a fixed exchange ratio of 0.211 Operating Partnership units for each limited partnership unit in the Mills LP. As a result of the change in control of Mills, holders of Mills’ $316.3 million in Series F Convertible Cumulative Redeemable Preferred Stock have the right to require that Mills repurchase their shares for cash equal to the liquidation preference per share plus accrued and unpaid dividends. If all of the holders of Mills’ Series F preferred stock exercise this right, Mills will be required to pay approximately $333 million.

22

We have and intend to obtain all funds necessary to fulfill our equity requirement to SPG-FCM, as well as any funds that we have or will provide in the form of loans to Mills, from available cash and the Credit Facility. Beginning in the second quarter of 2007, Simon Property or an affiliate will also begin to serve as the manager for substantially all of the 38 properties in which SPG-FCM holds an interest. At the end of the second quarter of 2007, we would expect to have funded $650 million of equity and have outstanding loans to Mills and SPG-FCM totaling approximately $1 billion.

Cash Flows

Our net cash flow from operating activities and distributions of capital from unconsolidated entities for the three months ended March 31, 2007 totaled $384.4 million. In addition, we had net proceeds from all of our debt financing and repayment activities in this period of $1.5 billion. These activities are further discussed below in Financing and Debt. We also:

·       repurchased units and preferred units amounting to $15.0 million,

·       paid unitholder distributions of $236.0 million,

·       paid preferred unit distributions totaling $19.6 million,

·       funded consolidated capital expenditures of $205.7 million. These capital expenditures include development costs of $121.5 million, renovation and expansion costs of $54.8 million, and tenant costs and other operational capital expenditures of $29.4 million, and

·       funded investments in unconsolidated entities of $431.9 million.

In general, we anticipate that cash generated from operations will be sufficient to meet operating expenses, monthly debt service, recurring capital expenditures, and distributions necessary to maintain Simon Property’s REIT qualification for 2007 and on a long-term basis. In addition, we expect to be able to obtain capital for nonrecurring capital expenditures, such as acquisitions, major building renovations and expansions, as well as for scheduled principal maturities on outstanding indebtedness, from:

·       excess cash generated from operating performance and working capital reserves,

·       borrowings on our Credit Facility,

·       additional secured or unsecured debt financing, or

·       additional equity raised in the public or private markets.

Financing and Debt

Unsecured Debt

Credit Facility.   Other significant draws on the Credit Facility during the three months ended March 31, 2007 were as follows:

Other amounts drawn on the Credit Facility were primarily for general working capital purposes. We repaid a total of $170.0 million on the Credit Facility during the three months ended March 31, 2007. The total outstanding balance on the Credit Facility as of March 31, 2007 was $1.8 billion, and the maximum

23

amount outstanding during the quarter was approximately $2.0 billion. During the first three months of 2007, the weighted average outstanding balance on the Credit Facility was approximately $741.0 million.

Secured Debt

Total secured indebtedness was $4.6 billion and $4.4 billion at March 31, 2007 and December 31, 2006, respectively. During the three months ended March 31, 2007, we repaid $122.4 million in mortgage loans, unencumbering two properties.

As a result of the acquisition of Mills by SPG-FCM, at March 31, 2007, we now hold a controlling ownership interest in Gwinnett Place and Town Center at Cobb, and as a result we now consolidate these two Properties. Included in this consolidation are two mortgages secured by Gwinnett Place of $35.6 million and $79.2 million at fixed rates of 7.54% and 7.25%, respectively, and two mortgages secured by Town Center at Cobb of $45.4 million and $60.3 million at fixed rates of 7.54% and 7.25%, respectively.

Summary of Financing

Our consolidated debt, adjusted to reflect outstanding derivative instruments, and the effective weighted average interest rates as of March 31, 2007 and December 31, 2006 consisted of the following (dollars in thousands):
