Management's Discussion and Analysis of Financial Condition and Results of Operations
Simon Property Group, Inc. and Subsidiaries

You should read the following discussion in conjunction with the consolidated financial statements and notes thereto that are included in this Annual Report to Stockholders. 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 discuss these and other risks and uncertainties under the heading "Risk Factors" in our Annual Report on Form 10-K that could cause our actual results to differ materially from the forward-looking statements that we make. We may update that discussion in subsequent quarterly 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, Inc. ("Simon Property") is a Delaware corporation that operates as a self-administered and self-managed real estate investment trust ("REIT"). To qualify as a REIT, among other things, a company must distribute at least 90 percent of its taxable income to its stockholders annually. Taxes are paid by stockholders on ordinary dividends received and any capital gains distributed. Most states also follow this federal treatment and do not require REITs to pay state income tax. Simon Property Group, L.P. (the "Operating Partnership") is a majority-owned partnership subsidiary of Simon Property that owns all of our real estate properties. In this discussion, the terms "we", "us" and "our" refer to Simon Property, the Operating Partnership, and their 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 December 31, 2006, we owned or held an interest in 286 income-producing properties in the United States, which consisted of 171 regional malls, 69 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 five parcels of land held in the United States for future development (together with the Properties, the "Portfolio"). In the United States, we have five new properties currently under development aggregating approximately 3.5 million square feet which will open during 2007 or early 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.

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.

64

We seek growth in our earnings, funds from operations ("FFO"), 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, and
•
  The acquisition of high quality real estate assets or portfolios of assets,
•
  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 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.

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 common share increased $0.37 during 2006, or 20.3%, to $2.19 from $1.82 for 2005. The 2006 results include a $34.4 million gain (or $0.12 per diluted share) 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, an $86.5 million gain related to our receipt of capital transaction proceeds and recognition of $15.6 million in income during 2006 (aggregating $0.36 per diluted share) from contributed beneficial interests, representing the right to receive cash flow, capital distributions, and related profits and losses of Mall of America Associates ("MOAA"), and increases in Portfolio operations. Included in 2005 results is a $125.1 million gain (or $0.45 per diluted share) realized upon the disposition of the Riverway and O'Hare International Center office building properties.

Our core business fundamentals remained strong during 2006. Regional mall comparable sales per square foot ("psf") strengthened in 2006, increasing 5.8% to $476 psf from $450 psf in 2005, reflecting robust retail sales activity. Our regional mall average base rents increased 2.6% to $35.38 psf from $34.49 psf. In addition, our regional mall leasing spreads were $6.48 psf as of December 31, 2006, compared to $7.40 psf as of December 31, 2005, principally as a result of changes in leasing mix. The operating fundamentals of the Premium Outlet centers and community/lifestyle centers also contributed to the improved 2006 operating results, as seen in the following section entitled Portfolio Data. Finally, regional mall occupancy was 93.2% as of December 31, 2006, as compared to 93.1% as of December 31, 2005. During 2006, we disposed of three consolidated properties that had an aggregate book value of $39.4 million for aggregate sales proceeds of $43.9 million, resulting in a net gain on sale of $4.5 million. We also sold a property

65

accounted for under the equity method of accounting for $8.8 million and recorded a gain of $7.7 million on its disposition.

We continue to identify additional opportunities in various international markets. We look to continue to focus on our joint venture interests in Europe, Japan, and other market areas abroad. In 2005, we realigned the interests in Simon Ivanhoe S.à.r.l. ("Simon Ivanhoe") with the result that our ownership and our new partner's ownership were increased to 50% each in the first quarter of 2006. In 2006, we increased our presence in Europe with the opening of Gliwice Shopping Center in Poland, a 380,000 square-foot center, and Giugliano in Italy, a 748,000 square foot center. We also opened expansions to a Premium Outlet center in Toki, Japan and a shopping center in Wasquehal, France. We expect international development and redevelopment/expansion activity for 2007 to include:

•
  Continuing construction by our Italian joint venture, Gallerie Commerciali Italia ("GCI"), of four shopping centers in Napoli, Roma, Nola (Napoli), and Milano with a gross leasable area ("GLA") of nearly 3.0 million square feet;
•
  Completing and opening of Kobe-Sanda Premium Outlets, a 185,000 square foot Premium Outlet center located in Kobe, Japan, in which we hold a 40% ownership interest;
•
  Completing and opening of Yeoju Premium Outlets, a 253,000 square foot Premium Outlet center located in South Korea. We hold a 50% ownership interest this property; and
•
  Continuing construction on four Wal-Mart anchored shopping centers, and commencement of a fifth shopping center, all located in China. We hold a 32.5% ownership interest in these centers.

Despite a significantly increasing interest rate environment that resulted in an approximate 93 basis point increase in LIBOR (5.32% at December 31, 2006 versus 4.39% at December 31, 2005), our effective overall borrowing rate for the twelve months ended December 31, 2006 decreased five basis points as compared to the twelve months ended December 31, 2005. Our financing activities for the twelve months ended December 31, 2006 are highlighted by the following:

•
  We repaid $609.1 million in unsecured notes and term loans that bore interest ranging from 6.875% to 7.38%.
•
  We paid off seven mortgages, unencumbering four properties, totaling $275.8 million that bore interest at fixed rates ranging from 6.76% to 8.25% and a variable rate of LIBOR plus 138 basis points.
•
  We made the final $600 million payment on the facility we used to fund the cash portion of our 2004 acquisition of Chelsea Property Group, Inc. ("Chelsea").
•
  On March 31, 2006, Standard & Poor's Rating Services raised our corporate credit rating to 'A-' from 'BBB+' which resulted in a decrease in the interest rate applicable to borrowings on our unsecured revolving $3 billion credit facility (the "Credit Facility") to 37.5 basis points over LIBOR from 42.5 basis points over LIBOR. The revision to our rating also decreased the facility fee on the Credit Facility to 12.5 basis points from 15 basis points.
•
  We issued two tranches of senior unsecured notes in May totaling $800 million at a weighted average fixed interest rate of 5.93%. We used the net proceeds of $803.9 million, which includes $10.1 million proceeds from terminated forward-starting swap arrangements, to reduce the borrowings on our Credit Facility.
•
  We issued two tranches of senior unsecured notes in August totaling $1.1 billion at a weighted average fixed interest rate of 5.73%. We used the proceeds of the offering to reduce borrowings on our Credit Facility.
•
  We issued two tranches of senior unsecured notes in December totaling $1.25 billion at a weighted average fixed interest rate of 5.13%. We used the proceeds of the offering to reduce borrowings on our Credit Facility and reinvested the remaining $577.4 million to be used for general working capital purposes.
•
  The outstanding balance of our Credit Facility decreased to approximately $305.1 million during the twelve months ended December 31, 2006, principally as a result of the above repayments. The December 31, 2006 outstanding balance consisted of Euro and Yen denominated borrowings only.
•
  As a result of the acquisition of the remaining 50% interest in Mall of Georgia on November 1, 2006, we now own 100% of the mall, and the property was consolidated as of the acquisition date. This included the consolidation of the $192.0 million fixed rate mortgage on this property.

  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 despite the current economic climate.

67

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 and community/lifestyle 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.

Critical Accounting Policies

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America, or GAAP, requires management to use judgment in the application of accounting policies, including making estimates and assumptions. We base our estimates on historical experience and on various other assumptions believed to be reasonable under the circumstances. These judgments affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenue and expenses during the reporting periods. If our judgment or interpretation of the facts and circumstances relating to various transactions had been different, it is possible that different accounting policies would have been applied resulting in a different presentation of our financial statements. From time to time, we evaluate our estimates and assumptions. In the event estimates or assumptions prove to be different from actual results, adjustments are made in subsequent periods to reflect more current information. Below is a discussion of accounting policies that we consider critical in that they may require complex judgment in their application or require estimates about matters that are inherently uncertain. For a summary of all of our significant accounting policies, see Note 3 of the Notes to Consolidated Financial Statements.

•
  We, as a lessor, retain substantially all of the risks and benefits of ownership of the investment properties and account for our leases as operating leases. We accrue minimum rents on a straight-line basis over the terms of their respective leases. Substantially all of our retail tenants are also required to pay overage rents based on sales over a stated base amount during the lease year. We recognize overage rents only when each tenant's sales exceeds its sales threshold.
•
  We review Properties for impairment on a case-by-case basis whenever events or changes in circumstances indicate that our carrying value may not be recoverable. These circumstances include, but are not limited to, declines in cash flows, occupancy and sales per square foot. Changes in our estimates of the future undiscounted cash flows as well as the holding period for each Property could affect our conclusion on whether an impairment charge is necessary. We recognize an impairment of investment property when we estimate that the undiscounted cash flows are less than the carrying value of the Property. To the extent an impairment has occurred, we charge to income the excess of the carrying value of the Property over its estimated fair value. We may decide to sell Properties that are held for use and the sales prices of these Properties may differ from their carrying values.

•
  To maintain our status as a REIT, we must distribute at least 90% of our taxable income in any given year and meet certain asset and income tests. The American Jobs Creation Act of 2004 builds in some flexibility to the REIT tax rules and imposes at most, monetary penalties in lieu of REIT disqualification, for the failure to meet certain REIT rules. These REIT savings provisions apply to issues discovered by the REIT after October 22, 2004. We monitor our business and transactions that may potentially impact our REIT status. In the unlikely event that we fail to maintain our REIT status, and we are not able to avail ourselves of the REIT savings provisions, then we would be required to pay federal income taxes at regular corporate income tax rates during the period we did not qualify as a REIT. If we lost our REIT status, we could not elect to be taxed as a REIT for four years unless our failure was due to reasonable cause and certain other conditions were met. As a result, failing to maintain REIT status would result in a significant increase in the income tax expense recorded during those periods.
•
  We make estimates as part of our allocation of the purchase price of acquisitions to the various components of the acquisition based upon the relative value of each component. The most significant components of our allocations are typically the allocation of fair value to the buildings as-if-vacant, land and market value of in-place leases. In the case of the fair value of buildings and the allocation of value to land and other intangibles, our estimates of the values of these components will affect the amount of depreciation we record over the estimated useful life of the property acquired or the remaining lease term. In the case of the market value of in-place leases, we make our best estimates of the tenants' ability to pay rents based upon the tenants' operating performance at the property, including the competitive position of the property in its market as well as sales psf, rents psf, and overall occupancy cost for the tenants in place at the acquisition date. Our assumptions affect the amount of future revenue that we will recognize over the remaining lease term for the acquired in-place leases.
•
  A variety of costs are incurred in the acquisition, development and leasing of properties. After determination is made to capitalize a cost, it is allocated to the specific component of a project that is benefited. Determination of when a development project is substantially complete and capitalization must cease involves a degree of judgment. Our capitalization policy on development properties is guided by SFAS No. 34 "Capitalization of Interest Cost" and SFAS No. 67 "Accounting for Costs and the Initial Rental Operations of Real Estate Properties." The costs of land and buildings under development include specifically identifiable costs. The capitalized costs include pre-construction costs essential to the development of the property, development costs, construction costs, interest costs, real estate taxes, salaries and related costs and other costs incurred during the period of development. We consider a construction project as substantially completed and held available for occupancy and cease capitalization of costs upon opening.

Year Ended December 31, 2006 vs. Year Ended December 31, 2005

Minimum rents, excluding rents from our consolidated Simon Brand and Simon Business initiatives, increased $75.7 million during the period, of which the Property Transactions accounted for $21.2 million of the increase. Total amortization of the fair market value of in-place leases increased minimum rents by $5.3 million. Comparable rents, excluding rents from Simon Brand and Simon Business, increased $54.5 million, or 2.9%. This was primarily due to leasing space at higher rents, resulting in an increase in base rents of $51.9 million. In addition, rents from carts, kiosks, and other temporary tenants increased comparable rents by $4.3 million in 2006.

Overage rents increased $10.2 million or 12.0%, reflecting the increases in tenants' rents, particularly in the Premium Outlet centers.

Tenant reimbursements, excluding Simon Business initiatives, increased $46.9 million. The Property Transactions accounted for $11.8 million. The remainder of the increase of $35.1 million, or 4.0%, was in comparable Properties and was due to inflationary increases in property operating costs.

Management fees and other revenues increased $4.5 million primarily due to increased leasing and development fees generated through our support activities provided to new joint venture Properties.

Management's Discussion and Analysis of Financial Condition and Results of Operations
Simon Property Group, Inc. and Subsidiaries

Total other income, excluding consolidated Simon Brand and Simon Business initiatives, increased $22.8 million. The aggregate increase in other income included the following significant activity:

•
  $11.9 million increase in our land sales activity on consolidated Properties;
•
  $6.4 million increase in interest income as a result of increasing investment rates;
•
  $3.7 million increase related to a gain on sale of a holding in a technology venture by Chelsea; and
•
  a $0.8 million increase in other net activity of the comparable Properties.

Consolidated revenues from Simon Brand and Simon Business initiatives increased $5.1 million to $162.2 million from $157.1 million. The increase in revenues is primarily due to increased event and sponsorship income, offset by decreased revenue as a result of structural changes to the gift card program.

Simon Brand and Simon Business expenses decreased $11.4 million that primarily resulted from decreased operating expenses of the co-branded gift card program, which are included in total property operating expenses.

Property operating expenses increased $19.6 million, $18.4 million of which was on comparable properties (representing an increase of 4.4%) and was principally as a result of inflationary increases.

Home office and regional costs increased $12.0 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 program.

Other expenses increased $6.6 million primarily due to increases in ground rent expenses of $3.9 million and increased professional fees.

Interest expense increased $22.8 million due to the impact of increased debt, primarily as a result of the issuances of unsecured notes in May, August, and December of 2006, and the annualized effect of our unsecured notes issued in June and November of 2005.

Income from unconsolidated entities and beneficial interests increased $29.0 million primarily due to favorable results of operations at the joint venture properties, plus the increase in ownership of Simon Ivanhoe and the recording of income from our beneficial interest in MOAA of $15.6 million.

We recorded a $132.8 million net gain on the sales of assets and interests in unconsolidated entities in 2006 that included a gain related to the sale of a beneficial interest of $86.5 million, a $34.4 million gain on the sale of 10.5% interest in Simon Ivanhoe, and the net gain on the sale of four non-core properties, including one joint venture property, of $12.2 million.

The increase in the Limited Partner interest of $52.8 million is primarily due to the increases in our income from continuing operations.

Discontinued operations for 2005 included the net operating results of properties sold, including the sale of underlying ground adjacent to the Riverway and O'Hare International Center properties. There were no discontinued operations in 2006.

In 2005, the gain on sale of discontinued operations of $115.8 million, net of the limited partners' interest, principally represents the net gain upon disposition of seven non-core Properties consisting of four regional malls, two office buildings, and one community/lifestyle center.

Preferred dividends increased due to the net impact of the redemption of the Series F Preferred Stock, which resulted in a $7.0 million charge to net income related to the redemption.

Year Ended December 31, 2005 vs. Year Ended December 31, 2004

Minimum rents, excluding rents from our consolidated Simon Brand and Simon Business initiatives, increased $393.3 million during the period. The net effect of the Property Transactions increased minimum rents $355.9 million of which $299.7 million was due to the operations of the Premium Outlet centers and other Properties acquired from Chelsea in October of 2004 (the "Chelsea Acquisition"). Total amortization of the fair market value of in-place leases increased minimum rents by $25.1 million, including the impact of the Property Transactions, principally the result of

72

the Chelsea Acquisition. Comparable rents, excluding rents from Simon Brand and Simon Business, increased $37.4 million, or 2.7%. This was primarily due to the leasing of space at higher rents that resulted in an increase in base rents of $30.1 million. In addition, increased rents from carts, kiosks, and other temporary tenants increased comparable rents by $6.7 million. Straight-line rents also increased by $12.9 million year over year.

Overage rents increased $19.2 million of which $15.7 million related to the Property Transactions, principally the Chelsea Acquisition. Comparable overage rents increased $3.5 million.

Tenant reimbursements, excluding Simon Business initiatives, increased $142.3 million. The Property Transactions accounted for $122.0 million of this increase, $98.3 million of which was due to the Chelsea Acquisition. The remainder of the increase of $20.3 million, or 2.8%, was in comparable Properties and was due to inflationary increases in property operating expenses, resulting in higher reimbursements.

Management fees and other revenues increased $5.0 million primarily due to increased leasing and development fees generated through our support activities provided to new joint venture Properties.

Total other income, excluding consolidated Simon Brand and Simon Business initiatives, decreased $1.3 million. The aggregate decrease in other income included the following significant activity:

•
  $26.0 million decrease in our land sales activity on consolidated Properties;
•
  the effect of the Property Transactions, principally Chelsea, which contributed $5.7 million to the increase for the ancillary fees received from the Japanese Premium Outlet Properties;
•
  increase in interest income of $8.0 million;
•
  collection of a $4.1 million note receivable that had been previously reserved for;
•
  $2.5 million gain on the sale of air rights at the Villages at Southpark in North Carolina;
•
  $2.2 million in gains related to the sale of stock received in prior period bankruptcy proceedings; and
•
  $2.2 million in other net activity of the comparable Properties.

Consolidated revenues from Simon Brand and Simon Business initiatives increased $23.3 million to $155.0 million from $131.7 million. The increase in revenues is primarily due to:

•
  increased revenue from fees derived from our co-branded gift card programs,
•
  increased rents and fees from service providers,
•
  increased advertising rentals, and
•
  increased event and sponsorship income.

The increased revenues from Simon Brand and Simon Business were offset by a $1.9 million increase in Simon Brand and Simon Business expenses that primarily resulted from increased gift card and other operating expenses, which are reported with property operating expenses in our consolidated statements of operations and comprehensive income.

Property operating expenses increased $65.9 million, $14.8 million of which was on comparable properties (representing an increase of 4.4%) and was principally as a result of inflationary increases. The remainder of the increase in property operating expenses was due to the effect of Property Transactions, principally the Chelsea Acquisition.

Depreciation and amortization expenses increased $242.8 million primarily due in large part to the net effect of the Property Transactions. The Chelsea Acquisition accounted for $191.1 million of the increase. Comparable properties depreciation and amortization increased $9.6 million, or 1.8%, due to the effect of our expansion and renovation activities.

Real estate taxes increased $46.2 million, due principally to the Property Transactions. The Chelsea Acquisition accounted for $32.3 million of the increase. The increase for the comparable properties was $9.3 million, or 4.0%.

Repairs and maintenance increased $16.2 million due principally to the Property Transactions. The Chelsea Acquisition accounted for $9.7 million of the increase. The comparable properties increased $4.5 million, or 5.4%.

73

Advertising and promotion expenses increased $23.6 million, of which $24.7 million was due to the Property Transactions, offset by a $1.1 million decrease on comparable properties.

Provision for credit losses decreased $8.9 million from the prior period due to a reduction of gross receivables, an overall improvement in quality of the receivables, and recoveries of amounts previously written off or provided for in prior periods.

Home office and regional costs increased $26.2 million due to the Property Transactions, primarily due to the Chelsea Acquisition and the additional costs of operating the Roseland, NJ offices, and incentive compensation arrangements.

Other expenses increased $18.3 million due to increases in ground rent expenses of $5.1 million and increases in professional fees and legal fees.

Interest expense increased $145.3 million due to the following:

•
  the effect of the borrowings to finance the Property Transactions, including $41.4 million related to the Acquisition Facility,
•
  the consolidation and/or acquisition of debt related to Property Transactions, principally the Chelsea Acquisition, which increased interest expense by $50.4 million,
•
  increased average borrowings resulting from the impact of an unsecured note offering in August of 2004, and
•
  increases in our average borrowing rates for our variable rate debt.

Income from unconsolidated entities for 2005 was comparable to the results of our income from consolidated entities for 2004. This includes an increase in the aggregate operations of our joint venture Properties, as a result of our acquisition activity and redevelopment/expansion, offset by an increase in the amount of depreciation and amortization related to acquired properties, principally as a result of the Chelsea Acquisition. The total number of joint venture properties increased from 124 in 2004 to 126 in 2005.

We recorded a $0.8 million net loss on the sales of interests in unconsolidated entities in 2005 that included our share of the loss on the sale of Forum Entertainment Center of $13.7 million, offset by our share of the gain on the sale of Metrocenter of $11.8 million and a $1.3 million net gain on the sale of a property management entity acquired as part of a 2002 acquisition.

In 2005, the gain on sale of discontinued operations of $115.8 million, net of the limited partners' interest principally represents the net gain upon disposition of seven non-core Properties consisting of four regional malls, two office buildings, and one community/lifestyle center.

The results of operations from discontinued operations includes the net operating results of properties sold, including the sale of underlying ground adjacent to the Riverway and O'Hare International Center properties. We believe these dispositions will not have a material adverse effect on our results of operations or liquidity.

Preferred distributions of the Operating Partnership increased by $6.9 million and preferred dividends increased $31.5 million due to the preferred stock and preferred units issued in the Chelsea Acquisition.

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 6% of our total consolidated debt. 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 distributions of capital from unconsolidated entities that totaled $1.5 billion during 2006. In addition, our Credit Facility provides an alternative source of liquidity as our cash needs vary from time to time.

74

Our balance of cash and cash equivalents increased $592.3 million during 2006 to $929.4 million as of December 31, 2006, principally as a result of excess proceeds resulting from the issuance of additional unsecured notes in December of 2006. The December 31, 2006 and 2005 balances include $27.2 million and $42.3 million, respectively, related to our co-branded gift card programs, which we do not consider available for general working capital purposes.

On December 31, 2006, our Credit Facility had available borrowing capacity of approximately $2.7 billion, net of outstanding borrowings of $305.1 million and letters of credit of $20.0 million. During 2006, the maximum amount outstanding under our Credit Facility was $2.0 billion and the weighted average amount outstanding was $1.1 billion. The weighted average interest rate was 4.80% for the year ended December 31, 2006.

On March 31, 2006, Standard & Poor's Rating Services raised its corporate credit rating for us to 'A-' from 'BBB+' which resulted in a decrease in the interest rate applicable to borrowings on our unsecured revolving $3 billion credit facility (the "Credit Facility") to 37.5 basis points over LIBOR from 42.5 basis points over LIBOR. The revision to our rating also decreased the facility fee on our Credit Facility to 12.5 basis points from 15 basis points. On November 1, Moody's Investors Service raised our senior unsecured debt rating to A3.

We and the Operating Partnership 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

On February 16, 2007, SPG-FCM Ventures, LLC ("SPG-FCM") a newly formed joint venture owned 50% by an entity owned by Simon Property and 50% by funds managed by Farallon Capital Management, L.L.C. ("Farallon") entered into a definitive merger agreement with The Mills Corporation ("Mills") pursuant to which SPG-FCM will acquire Mills for $25.25 per common share in cash. The total value of the transaction is approximately $1.64 billion for all of the outstanding common stock of Mills and common units of The Mills Limited Partnership ("Mills LP") not owned by Mills, and approximately $7.3 billion, including assumed debt and preferred stock.

The acquisition will be completed through a cash tender offer at $25.25 per share for all outstanding shares of Mills common stock, which is expected to conclude in late March or early April 2007. If successful, the tender offer will be followed by a merger in which all shares not acquired in the offer will be converted into the right to receive the offer price. Completion of the tender offer is subject to the receipt of valid tenders of sufficient shares to result in ownership of a majority of Mills' fully diluted common shares and the satisfaction of other customary conditions. As part of the merger following the successful completion of the tender offer, Mills LP common unitholders 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 upon a fixed exchange ratio of 0.211 Operating Partnership units for each unit of Mills LP.

In connection with the proposed transaction, we made a loan to Mills on February 16, 2007 to permit it to repay a loan facility provided by a previous bidder for Mills. The $1.188 billion loan to Mills carries a rate of LIBOR plus 270 basis points. The loan facility also permits Mills to borrow an additional $365 million on a revolving basis for working capital requirements and general corporate purposes. Simon Property or an affiliate of Mills will serve as the manager for all or a portion of the 38 properties that SPG-FCM will acquire an interest in following the completion of the tender offer.

We will be required to provide at least 50% of the funds necessary to complete the tender offer and any additional amounts required to complete the acquisition of Mills. We have and intend to obtain all funds necessary to fulfill our equity requirement for SPG-FCM, as well as any funds that we have or will provide in the form of loans to Mills, from available cash and our Credit Facility.

Cash Flows

Our net cash flow from operating activities and distributions of capital from unconsolidated entities totaled $1.5 billion during 2006. We also received proceeds of $209.0 million from the sale of partnership interests and the

75

sales of assets during 2006. In addition, we received net proceeds from all of our debt financing and repayment activities in 2006 of $1.1 billion. These activities are further discussed below in "Financing and Debt". We also:

•
  repurchased preferred stock and limited partner units amounting to $409.7 million,
•
  paid stockholder dividends and unitholder distributions totaling $849.5 million,
•
  paid preferred stock dividends and preferred unit distributions totaling $104.7 million,
•
  funded consolidated capital expenditures of $767.7 million. These capital expenditures include development costs of $317.2 million, renovation and expansion costs of $306.6 million, and tenant costs and other operational capital expenditures of $143.9 million, and
•
  funded investments in unconsolidated entities of $157.3 million.

In general, we anticipate that cash generated from operations will be sufficient to meet operating expenses, monthly debt service, recurring capital expenditures, and distributions to stockholders necessary to maintain our REIT qualification 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

We have $1.0 billion of unsecured notes issued by a subsidiary that are structurally senior in right of payment to holders of other unsecured notes to the extent of the assets and related cash flows of certain Properties. These unsecured notes have a weighted average interest rate of 7.02% and weighted average maturities of 5.3 years.

On May 15, 2006, we sold two tranches of senior unsecured notes totaling $800 million at a weighted average fixed interest rate of 5.93%. The first tranche is $400.0 million at a fixed interest rate of 5.75% due May 1, 2012 and the second tranche is $400.0 million at a fixed interest rate of 6.10% due May 1, 2016. We used the proceeds of the offering and the termination of forward-starting interest rate swap arrangements to reduce borrowings on our Credit Facility.

On August 29, 2006, we sold two tranches of senior unsecured notes totaling $1.1 billion at a weighted average fixed interest rate of 5.73%. The first tranche is $600.0 million at a fixed interest rate of 5.60% due September 1, 2011 and the second tranche is $500.0 million at a fixed interest rate of 5.875% due March 1, 2017. We used proceeds from the offering to reduce borrowings on our Credit Facility.

On December 12, 2006, we sold two tranches of senior unsecured notes totaling $1.25 billion at a weighted average fixed interest rate of 5.13%. The first tranche is $600.0 million at a fixed interest rate of 5.00% due March 1, 2012 and the second tranche is $650.0 million at a fixed interest rate of 5.25% due December 1, 2016. We used proceeds from the offering to reduce borrowings on our Credit Facility and reinvested the remainder of the proceeds of approximately $577.4 million to be used for general working capital purposes.

01/06/06 |  |  | 140,000 |  | Repayment of a mortgage, which had a rate of LIBOR plus 137.5 basis points.
01/20/06 |  |  | 300,000 |  | Repayment of unsecured notes, which had a fixed rate of 7.375%.
03/27/06 |  |  | 600,000 |  | Early repayment of the $1.8 billion facility we used to finance our acquisition of Chelsea in 2004.
04/03/06 |  |  | 58,000 |  | Repayment of two secured mortgages which each bore interest at 8.25%.

11/15/06 |  |  | 250,000 |  | Repayment of unsecured notes, which had a fixed rate of 6.875%.

Other amounts drawn on our Credit Facility during the period were primarily for general working capital purposes. We repaid a total of $2.8 billion on our Credit Facility during the year ended December 31, 2006. The total outstanding balance on our Credit Facility as of December 31, 2006 was $305.1 million, and the maximum amount outstanding during the year was approximately $2.0 billion. During the year ended December 31, 2006, the weighted average outstanding balance on our Credit Facility was approximately $1.1 billion.

Acquisition Facility. We borrowed $1.8 billion in 2004 to finance the cash portion of our acquisition of Chelsea. As disclosed above, this facility has been fully repaid.

Secured Debt

Total secured indebtedness was $4.4 billion and $4.6 billion at December 31, 2006 and 2005, respectively. During the twelve-month period ended December 31, 2006, we repaid $275.8 million in mortgage loans, unencumbering four properties.

As a result of the acquisition of the November 1, 2006 purchase of the remaining 50% interest in Mall of Georgia from our partner, we now own 100% of this Property, and consolidated it as of the acquisition date. This included the consolidation of its $192.0 million 7.09% fixed-rate mortgage.

Summary of Financing

Our consolidated debt, adjusted to reflect outstanding derivative instruments and the effective weighted average interest rates for the years then ended consisted of the following (dollars in thousands):

Debt Subject to |  | Adjusted Balance as of December 31, 2006 |  | Effective Weighted Average Interest Rate |  | Adjusted Balance as of December 31, 2005 |  | Effective Weighted Average Interest Rate
--- | --- | --- | --- | --- | --- | --- | --- | ---
Fixed Rate |  | $ | 14,548,226 |  | 6.02% |  | $ | 11,908,050 |  | 6.22%
Variable Rate |  |  | 846,263 |  | 5.01% |  |  | 2,198,067 |  | 4.95%
|  | $ | 15,394,489 |  | 5.97% |  | $ | 14,106,117 |  | 6.02%

As of December 31, 2006, we had interest rate cap protection agreements on $95.7 million of consolidated variable rate debt. We also hold $370.0 million of notional amount variable rate swap agreements that have a weighted average variable pay rate of 5.36% and a weighted average fixed receive rate of 3.72%. As of December 31, 2006 and December 31, 2005, these agreements effectively converted $370.0 million and $310.9 million of fixed rate debt to variable rate debt, respectively.

(1)
  Represents principal maturities only and therefore, excludes net premiums and discounts and fair value swaps of $54,333.
(2)
  Represents our pro rata share of principal maturities and excludes net premiums and discounts.
(3)
  Represents our pro rata share of capital expenditure commitments.
(4)
  Represents only the minimum non-cancellable lease period, excluding applicable lease extension and renewal options.

Capital expenditure commitments presented in the table above represent new developments, redevelopments or renovation/expansions that we have committed to the completion of construction. The timing of these expenditures may vary due to delays in construction or acceleration of the opening date of a particular project. In addition, the amount includes our share of committed costs for joint venture developments.

Our off-balance sheet arrangements consist primarily of our investments in real estate joint ventures which are common in the real estate industry and are described in Note 7 of the notes to the accompanying financial statements. Joint venture debt is the liability of the joint venture, is typically secured by the joint venture Property, and is non-recourse to us. As of December 31, 2006, we have loan guarantees and other guarantee obligations to support $43.6 million and $19.0 million, respectively, to support our total $3.5 billion share of joint venture mortgage and other indebtedness presented in the table above.

Preferred Stock Activity

During 2006, six unitholders exchanged 230,486 units of the 6% Convertible Perpetual Preferred Units for an equal number of shares of Series I Preferred Stock, and we redeemed 11,377 units of Series I Preferred Units for cash. We issued a total of 222,933 shares of common stock to holders of Series I Preferred Stock who exercised their conversion rights. We had 42 unitholders convert 1,149,077 units of the 7% Cumulative Convertible Preferred Units into 869,574 units of the Operating Partnership. On October 4, 2006, we redeemed all 8,000,000 shares of the 83/4% Series F Cumulative Redeemable Preferred Stock, through the use of proceeds derived from the issuance of a new series of preferred stock (Series K) issued in a private transaction which was also repurchased prior to year end. As a result of this transaction we recorded a $7.0 million charge to net income.

78

Acquisitions and Dispositions

Buy/sell provisions are common in real estate partnership agreements. Most of our partners are institutional investors who have a history of direct investment in retail real estate. Our partners in our joint venture properties may initiate these provisions at any time and if we determine it is in our stockholders' best interests for us to purchase the joint venture interest and we believe we have adequate liquidity to execute the purchases of the interests without hindering our cash flows or liquidity, then we may elect to buy. Should we decide to sell any of our joint venture interests, we would expect to use the net proceeds from any such sale to reduce outstanding indebtedness or to reinvest in development, redevelopment, or expansion opportunities.

Acquisitions. The acquisition of high quality individual properties or portfolios of properties remain an integral component of our growth strategies.

On November 1, 2006, we acquired the remaining 50% interest in Mall of Georgia, a regional mall Property, from our partner for $252.6 million, including the assumption of our $96.0 million share of debt. As a result, we now own 100% of Mall of Georgia and the property was consolidated as of the acquisition date.

Dispositions. We continue to pursue the sale of Properties that no longer meet our strategic criteria. In 2006, we disposed of three consolidated properties and one property in which we held a 50% interest and accounted for under the equity method. We received net proceeds of $52.7 million and recorded our share of a gain on the disposals totaling $12.2 million. We do not believe the sale of these properties will have a material impact on our future results of operations or cash flows. We believe the disposition of these properties will enhance the average overall quality of our Portfolio. In addition, we also received capital transaction proceeds related to a beneficial interest that we held during 2006 in a mall partnership, which resulted in an $86.5 million gain, terminating our beneficial interests in this entity.

Development Activity

New U.S. Developments. The following describes certain of our new development projects, the estimated total cost, and our share of the estimated total cost and our share of the construction in progress balance as of December 31, 2006 (dollars in millions):

Property |  | Location |  | Gross Leasable Area |  | Estimated Total Cost(a) |  | Our Share of Estimated Total Cost |  | Our Share of Construction in Progress |  | Estimated Opening Date
--- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | ---
Under Construction: |  |  |  |  |  |  |  |  |  |  |  |

(a)
  Represents the project costs net of land sales, tenant reimbursements for construction, and other items (where applicable).

We expect to fund these projects with available cash flow from operations, borrowings from our Credit Facility, or project specific construction loans. We expect our share of total 2007 new development costs for these and our other planned new development projects to be approximately $600 million.

Strategic Expansions and Renovations. In addition to new development, we also incur costs related to construction for significant renovation and/or expansion projects at our properties. Included in these projects are the

79

renovation and addition of Crate & Barrel and Nordstrom at Burlington Mall, expansions and life-style additions at Lehigh Valley Mall, Smith Haven Mall and Town Center at Boca Raton, a Neiman Marcus expansion at Lenox Square, addition of Phase II expansions at Las Vegas Premium Outlets, Orlando Premium Outlets, and St. Johns Town Center, and the acquisition and renovation of several anchor stores previously operated by Federated.

We expect to fund these capital projects with available cash flow from operations or borrowings from our Credit Facility. We expect to invest a total of approximately $675 million (our share) on expansion and renovation activities in 2007.

Capital Expenditures on Consolidated Properties.

The following table summarizes total capital expenditures on consolidated Properties on a cash basis:

|  | 2006 |  | 2005 |  | 2004
--- | --- | --- | --- | --- | --- | ---
New Developments |  | $ | 317 |  | $ | 341 |  | $ | 215
Renovations and Expansions |  |  | 307 |  |  | 252 |  |  | 244
Tenant Allowances |  |  | 52 |  |  | 69 |  |  | 73
Operational Capital Expenditures |  |  | 92 |  |  | 64 |  |  | 17
Total |  | $ | 768 |  | $ | 726 |  | $ | 549

International. We typically reinvest net cash flow from our international investments 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 our European investments with Euro-denominated borrowings that act as a natural hedge against local currency fluctuations. This has also been the case with our Premium Outlet joint ventures in Japan and Mexico where we use Yen and Peso denominated financing. We expect our share of international development for 2007 to approximate $200 million.

Currently, our net income exposure to changes in the volatility of the Euro, Yen, Peso and other foreign currencies is not material. In addition, since cash flows from operations are currently being reinvested in other development projects, we do not expect to repatriate foreign denominated earnings in the near term.

The carrying amount of our total combined investment in Simon Ivanhoe and Gallerie Commerciali Italia ("GCI"), as of December 31, 2006, net of the related cumulative translation adjustment, was $338.1 million. Our investments in Simon Ivanhoe and GCI are accounted for using the equity method of accounting. Currently four European developments are under construction which will add approximately 3 million square feet of GLA for a total net cost of approximately €571 million, of which our share is approximately €151 million, or $199 million based on current Euro:USD exchange rates.

On October 20, 2005, Ivanhoe Cambridge, Inc. ("Ivanhoe"), an affiliate of Caisse de dépôt et placement du Québec, effectively acquired our former partner's 39.5% ownership interest in Simon Ivanhoe. On February 13, 2006, we sold a 10.5% interest in this joint venture to Ivanhoe for €45.2 million, or $53.9 million and recorded a gain on the disposition of $34.4 million. This gain is reported in "gain on sales of interests in unconsolidated entities" in the consolidated statements of operations. We then settled all remaining share purchase commitments from the company's founders, including the early settlement of some commitments by purchasing an additional 25.8% interest for €55.1 million, or $65.5 million. The result of these transactions equalized our and Ivanhoe's ownership in Simon Ivanhoe to 50% each.

As of December 31, 2006, the carrying amount of our 40% joint venture investment in the five Japanese Premium Outlet centers net of the related cumulative translation adjustment was $281.2 million. Currently, Kobe-Sanda Premium Outlets, a 185,000 square foot Premium Outlet Center, is under construction in Kobe, Japan. The project's total projected net cost is JPY 5.9 billion, of which our share is approximately JPY 2.4 billion, or $19.8 million based on current Yen:USD exchange rates.

80

In addition to the developments in Europe and Japan, construction has begun on Yeoju Premium Outlets, a 253,000 square foot center near Seoul, South Korea. The project's total projected net cost is KRW 78.7 billion, of which our share is approximately KRW 39.1 billion, or approximately $42.6 million based on current KRW:USD exchange rates.

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 in China, four of which are under construction as of December 31, 2006. Our total equity commitment for these centers approximates $60 million and as of December 31, 2006, our combined investment in GMI is approximately $15.9 million.

Distributions and Stock Repurchase Program

On February 2, 2007, our Board of Directors ("Board") approved an increase in the annual distribution rate by 10.5% to $3.36 per share. Dividends during 2006 aggregated $3.04 per share and dividends during 2005 aggregated $2.80 per share. We are required to pay a minimum level of dividends to maintain our status as a REIT. Our dividends and limited partner distributions typically exceed our net income generated in any given year primarily because of depreciation, which is a "non-cash" expense. Future dividends and the distributions of the Operating Partnership will be determined by the Board based on actual results of operations, cash available for dividends and limited partner distributions, and what may be required to maintain our status as a REIT.

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

Non-GAAP Financial Measure — Funds from Operations

Industry practice is to evaluate real estate properties in part based on funds from operations ("FFO"). We consider FFO to be a key measure of our operating performance that is not specifically defined by accounting principles generally accepted in the United States ("GAAP"). We believe that FFO is helpful to investors because it is a widely recognized measure of the performance of REITs and provides a relevant basis for comparison among REITs. We also use this measure internally to measure the operating performance of our Portfolio.

As defined by the National Association of Real Estate Investment Trusts ("NAREIT"), FFO is consolidated net income computed in accordance with GAAP:

•
  excluding real estate related depreciation and amortization,
•
  excluding gains and losses from extraordinary items and cumulative effects of accounting changes,
•
  excluding gains and losses from the sales of 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 change or resulting from the sale or disposal of depreciable real estate. However, you should understand that our computation of FFO might not be comparable to FFO reported by other REITs and that FFO:

•
  does not represent cash flow from operations as defined by GAAP,
•
  should not be considered as an alternative to net income determined in accordance with GAAP as a measure of operating performance, and

81

•
  is not an alternative to cash flows as a measure of liquidity.

The following schedule sets forth total FFO before allocation to the limited partners of the Operating Partnership and FFO allocable to Simon Property. This schedule also reconciles consolidated net income, which we believe is the most directly comparable GAAP financial measure, to FFO for the periods presented.

Management's Report On Internal Control Over Financial Reporting

We are responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is defined in Rule 13a-15(f) or 15d-15(f) promulgated under the Securities Exchange Act of 1934 as a process designed by, or under the supervision of, our principal executive and principal financial officers and effected by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles and includes those policies and procedures that:

•
  Pertain to the maintenance of records that in reasonable detail accurately and fairly reflect our transactions and disposition of asset;
•
  Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and
•
  Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

We assessed the effectiveness of our internal control over financial reporting as of December 31, 2006. In making this assessment, we used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control-Integrated Framework.

Based on that assessment, we believe that, as of December 31, 2006, our internal control over financial reporting is effective based on those criteria.

Our independent registered public accounting firm has issued an audit report on our assessment of our internal control over financial reporting. Their report appears on the following page of this Annual Report.

Report Of Independent Registered Public Accounting Firm

The Board of Directors and Stockholders of
Simon Property Group, Inc.:

We have audited management's assessment, included in the accompanying Management's Report on Internal Control Over Financial Reporting immediately preceding this report, that Simon Property Group, Inc. and Subsidiaries maintained effective internal control over financial reporting as of December 31, 2006, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (the COSO criteria). Simon Property Group, Inc. and Subsidiaries' management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting. Our responsibility is to express an opinion on management's assessment and an opinion on the effectiveness of the Company's internal control over financial reporting based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, evaluating management's assessment, testing and evaluating the design and operating effectiveness of internal control, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

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

1. Organization

Simon Property Group, Inc. ("Simon Property") is a Delaware corporation that operates as a self-administered and self-managed real estate investment trust ("REIT"). Simon Property Group, L.P. (the "Operating Partnership") is a majority-owned partnership subsidiary of Simon Property that owns all of our real estate properties. In these notes to consolidated financial statements, the terms "we", "us" and "our" refer to Simon Property, the Operating Partnership, and their 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 December 31, 2006, we owned or held an interest in 286 income-producing properties in the United States, which consisted of 171 regional malls, 69 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 five 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.

We generate the majority of our 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 substantially all of our recoverable expenditures, which consist of property operating, real estate tax, repairs and maintenance, and advertising and promotional expenditures.

We also generate revenues due to our size and tenant relationships from:

•
  Pursuing mall marketing initiatives, including payment systems (including marketing fees relating to the sales of bank-issued prepaid cards), national marketing alliances, static and digital media initiatives, business development, sponsorships, and events,
•
  Forming consumer focused strategic corporate alliances, and
•
  Offering property operating services to our tenants and others resulting from our relationships with vendors.

2. Basis of Presentation and Consolidation

The accompanying consolidated financial statements of Simon Property include the accounts of all majority-owned subsidiaries, and all significant intercompany amounts have been eliminated.

We consolidate Properties that are wholly owned or Properties that we own less than 100% but we control. Control of a Property is demonstrated by, among other factors, our ability to:

•
  manage day-to-day operations,
•
  refinance debt and sell the Property without the consent of any other partner or owner, and
•
  the inability of any other partner or owner to replace us.

We also consolidate all variable interest entities when we are determined to be the primary beneficiary.

The deficit minority interest balances included in deferred costs and other assets in the accompanying consolidated balance sheets represent outside partners' interests in the net equity of certain properties. We record deficit minority interests when a joint venture agreement provides for the settlement of deficit capital accounts before distributing the proceeds from the sale of joint venture assets or the joint venture partner is obligated to make additional contributions to the extent of any capital account deficits and has the ability to fund such additional contributions.

90

Investments in partnerships and joint ventures represent noncontrolling ownership interests in Properties. We account for these investments using the equity method of accounting. We initially record these investments at cost and we subsequently adjust for net equity in income or loss, which we allocate in accordance with the provisions of the applicable partnership or joint venture agreement, and cash contributions and distributions. The allocation provisions in the partnership or joint venture agreements are not always consistent with the legal ownership interests held by each general or limited partner or joint venture investee primarily due to partner preferences.

As of December 31, 2006, of our 345 properties we consolidated 199 wholly-owned properties and consolidated 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 remaining 127 properties using the equity method of accounting (joint venture properties). We manage the day-to-day operations of 58 of the 127 joint venture properties but have determined that our partner or partners have substantive participating rights in regards to the assets and operations of these joint venture properties.

We allocate net operating results of the Operating Partnership after preferred distributions to third parties and Simon Property based on the partners' respective weighted average ownership interests in the Operating Partnership.

Our weighted average ownership interest in the Operating Partnership was as follows:

|  | For the Year Ended December 31, |
--- | --- | --- | ---
|  | 2006 |  | 2005 |  | 2004 |
Weighted average ownership interest |  | 79.1 | % | 78.7 | % | 77.7 | %

As of December 31, 2006 and 2005, our ownership interest in the Operating Partnership was 78.9% and 79.0%, respectively. We adjust the limited partners' interest in the Operating Partnership at the end of each period to reflect their interest in the Operating Partnership.

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

3. Summary of Significant Accounting Policies

Investment Properties

We record investment properties at cost. Investment properties include costs of acquisitions; development, predevelopment, and construction (including salaries and related benefits); tenant allowances and improvements; and interest and real estate taxes incurred related to construction. We capitalize improvements and replacements from repair and maintenance when the repair and maintenance extend the useful life, increase capacity, or improve the efficiency of the asset. All other repair and maintenance items are expensed as incurred. We record depreciation on buildings and improvements utilizing the straight-line method over an estimated original useful life, which is generally 10 to 40 years. We review depreciable lives of investment properties periodically and we make adjustments when necessary to reflect a shorter economic life. We record depreciation on tenant allowances, tenant inducements and tenant improvements utilizing the straight-line method over the term of the related lease or occupancy term of the tenant, if shorter. We record depreciation on equipment and fixtures utilizing the straight-line method over seven to ten years.

We review investment properties for impairment on a property-by-property basis whenever events or changes in circumstances indicate that the carrying value of investment properties may not be recoverable. These circumstances include, but are not limited to, declines in cash flows, occupancy and comparable sales per square foot at the property. We recognize an impairment of investment property when the estimated undiscounted operating income before depreciation and amortization plus its residual value is less than the carrying value of the property. To the extent

91

impairment has occurred, we charge to income the excess of carrying value of the property over its estimated fair value. We may decide to sell properties that are held for use and the sale prices of these properties may differ from their carrying values.

Purchase Accounting Allocation

We allocate the purchase price of acquisitions to the various components of the acquisition based upon the relative value of each component in accordance with SFAS No. 141 "Business Combinations" (SFAS 141). These components typically include buildings, land and intangibles related to in-place leases and we estimate:

•
  the fair value of the buildings on an as-if-vacant basis. The value allocated to land and related improvements is determined either by real estate tax assessments, a third party valuation specialist, or other relevant data.
•
  the market value of in-place leases based upon our best estimate of current market rents and amortize the resulting market rent adjustment into revenues.
•
  the value of costs to obtain tenants, including tenant allowances and improvements and leasing commissions.
•
  the value of revenue and recovery of costs foregone during a reasonable lease-up period, as if the space was vacant.

Amounts allocated to building are depreciated over the estimated remaining life of the acquired building or related improvements. We amortize amounts allocated to tenant improvements, in-place lease assets and other lease-related intangibles over the remaining life of the underlying leases, either on a specific lease methodology for a portfolio acquisition or an average of total property leases methodology, generally applied for a single property acquisition, depending on the availability of estimates by lease. We also estimate the value of other acquired intangible assets, if any, which are amortized over the remaining life of the underlying related leases or intangibles. Any remaining amount of value will be allocated to in-place leases, as deemed appropriate under the circumstances.

Discontinued Operations

SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" ("SFAS No. 144") provides a framework for the evaluation of impairment of long-lived assets, the treatment of assets held for sale or to be otherwise disposed of, and the reporting of discontinued operations. SFAS No. 144 requires us to reclassify any material operations related to consolidated properties sold during the period to discontinued operations. We have reclassified the results of operations of the seven regional malls, community/lifestyle centers, and office building properties disposed during 2005 and five properties sold during 2004, as described in Note 4 to discontinued operations in the accompanying consolidated statements of operations and comprehensive income for 2005 and 2004. Revenues included in discontinued operations were $29.3 million for the year ended December 31, 2005 and $62.7 million for the year ended December 31, 2004. There were no discontinued operations reported in 2006, as assets sold in 2006 were not material.

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. During 2005, independent banks assumed responsibility for the gift card programs. We collect gift card funds at the point of sale and then remit those funds to the banks for further processing. As a result, cash and cash equivalents, as of December 31, 2006, includes a balance of $27.2 million related to these gift card programs which we do not consider available for general working capital purposes. See Notes 4, 8, and 10 for disclosures about non-cash investing and financing transactions.

92

Marketable Securities

Marketable securities consist primarily of the assets of our insurance subsidiaries and are included in deferred costs and other assets. The types of securities typically include U.S. Treasury or other U.S. government securities as well as corporate debt securities with maturities ranging from 1 to 10 years. These securities are classified as available-for-sale and are valued based upon quoted market prices or using discounted cash flows when quoted market prices are not available. The amortized cost of debt securities in this category 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 until the gain or loss is realized and recorded in other income. However, if we determine a decline in value is other than temporary, then we recognize the unrealized loss in income to write down the investments to their net realizable value. Our insurance subsidiaries are required to maintain statutory minimum capital and surplus as well as maintain a minimum liquidity ratio. Therefore, our access to their securities may be limited.

Accounting for Beneficial Interests in Mall of America

In January 2006, an entity controlled by the Simon family assigned to us its right to receive cash flow, capital distributions, and related profits and losses with respect to a portion of its ownership interest in the Mall of America through Mall of America Associates ("MOAA"). This beneficial interest was transferred subject to a credit facility repayable from MOAA's distributions from the property. As a result of this assignment, we began recognizing our share of MOAA's income during the first quarter of 2006, including the proportionate share of earnings of MOAA since August 2004 through the first quarter of 2006 of $10.2 million. This income is included with "income from unconsolidated entities and beneficial interests, net" in our consolidated statement of operations. We accounted for our beneficial interests in MOAA under the equity method of accounting. On November 2, 2006, the Simon family entity sold its partnership interest to an affiliate of another partner in MOAA and settled all pending litigation disclosed in Note 8, terminating our beneficial interests. As a result of this sale, we ceased recording income from this property's operations, and recorded a gain of approximately $86.5 million as a result of the receipt of $102.2 million of capital transaction proceeds assigned to us from this arrangement.

Use of Estimates

We prepared the accompanying consolidated financial statements in accordance with accounting principles generally accepted in the United States ("GAAP"). GAAP requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and revenues and expenses during the reported period. Our actual results could differ from these estimates.

Capitalized Interest

We capitalize interest on projects during periods of construction until the projects are ready for their intended purpose. The amount of interest capitalized during each year is as follows:

|  | For the Year Ended December 31,
--- | --- | ---
|  | 2006 |  | 2005 |  | 2004
Capitalized interest |  | $ | 30,115 |  | $ | 14,433 |  | $ | 14,612

Segment Disclosure

The Financial Accounting Standards Board (the "FASB") Statement No. 131, "Disclosures about Segments of an Enterprise and Related Information" ("Statement 131") requires disclosure of certain operating and financial data

93

with respect to separate business activities within an enterprise. Our primary business is the ownership, development, and management of retail real estate. We have aggregated our retail operations, including regional malls, Premium Outlet centers and community/lifestyle centers, into one reportable segment because they have similar economic characteristics and we provide similar products and services to similar types of tenants. Further, all material operations are within the United States and no customer or tenant comprises more than 10% of consolidated revenues.

Deferred Costs and Other Assets

Deferred costs and other assets include the following as of December 31:

|  | 2006 |  | 2005
--- | --- | --- | --- | ---
Deferred financing and lease costs, net |  | $ | 204,645 |  | $ | 183,249

|  | $ | 990,899 |  | $ | 938,301

Deferred Financing and Lease Costs. Our deferred costs consist primarily of financing fees we incurred in order to obtain long-term financing and internal and external leasing commissions and related costs. We record amortization of deferred financing costs on a straight-line basis over the terms of the respective loans or agreements. Our deferred leasing costs consist primarily of capitalized salaries and related benefits in connection with lease originations. We record amortization of deferred leasing costs on a straight-line basis over the terms of the related leases. We amortize debt premiums and discounts, which are included in mortgages and other indebtedness, over the remaining terms of the related debt instruments. These debt premiums or discounts arise either at the debt issuance or as part of the purchase price allocation of the fair value of debt assumed in acquisitions. Details of these deferred costs as of December 31 are as follows:

|  | 2006 |  | 2005 |
--- | --- | --- | --- | --- | ---
Deferred financing and lease costs |  | $ | 340,427 |  | $ | 337,919 |
Accumulated amortization |  |  | (135,782 | ) |  | (154,670 | )
Deferred financing and lease costs, net |  | $ | 204,645 |  | $ | 183,249 |

The accompanying statements of operations and comprehensive income includes amortization as follows:

|  | For the year ended December 31, |
--- | --- | --- | ---
|  | 2006 |  | 2005 |  | 2004 |
Amortization of deferred financing costs |  | $ | 18,716 |  | $ | 22,063 |  | $ | 17,188 |
Amortization of debt premiums net of discounts |  |  | (28,163 | ) |  | (26,349 | ) |  | (8,401 | )
Amortization of deferred leasing costs |  |  | 22,259 |  |  | 20,606 |  |  | 19,281 |

We report amortization of deferred financing costs, amortization of premiums, and accretion of discounts as part of interest expense. Amortization of deferred leasing costs are a component of depreciation and amortization expense.

94

Intangible Assets. The average life of the in-place lease intangibles is approximately 6.5 years and is amortized over the remaining life of the leases of the related property on the straight-line basis and is included with depreciation and amortization in the consolidated statements of operations and comprehensive income. The fair market value of above and below market leases are amortized into revenue over the remaining lease life as a component of reported minimum rents. The weighted average remaining life of these intangibles approximates 4.5 years. The unamortized amounts of below market leases are included in accounts payable, accrued expenses, intangibles and deferred revenues on the consolidated balance sheets and are $186.6 million and $261.9 million as of December 31, 2006 and 2005, respectively. The amount of amortization of above and below market leases, net for the year ended December 31, 2006, 2005, and 2004 was $53.3 million, $48.0 million, and $22.4 million, respectively.

Details of intangible assets as of December 31 are as follows:

|  | 2006 |  | 2005 |
--- | --- | --- | --- | --- | ---
In-place lease intangibles |  | $ | 183,544 |  | $ | 183,544 |
Accumulated amortization |  |  | (89,981 | ) |  | (55,954 | )

Accumulated amortization |  |  | (73,601 | ) |  | (48,134 | )
Fair market value of acquired above market lease intangibles, net |  | $ | 70,623 |  | $ | 96,090 |

Estimated future amortization, and the increasing (decreasing) effect on minimum rents for our above and below market leases recorded as of December 31, 2006 are as follows:

|  | Below Market Leases |  | Above Market Leases |  | Increase to Minimum Rent, Net
--- | --- | --- | --- | --- | --- | ---
2007 |  | $ | 63,760 |  | $ | (20,881 | ) | $ | 42,879

|  | $ | 186,611 |  | $ | (70,623 | ) | $ | 115,988

Derivative Financial Instruments

We account for our derivative financial instruments pursuant to SFAS 133 "Accounting for Derivative Instruments and Hedging Activities," as amended by SFAS 138, "Accounting for Derivative Instruments and Hedging Activities." We use a variety of derivative financial instruments in the normal course of business to manage or hedge the risks described in Note 8 and record all derivatives on our balance sheets at fair value. We require that hedging derivative instruments are effective in reducing the risk exposure that they are designated to hedge. We formally designate any instrument that meets these hedging criteria as a hedge at the inception of the derivative contract.

We adjust our balance sheets on an ongoing basis to reflect the current fair market value of our derivatives. We record changes in the fair value of these derivatives each period in earnings or comprehensive income, as appropriate. The ineffective portion of the hedge is immediately recognized in earnings to the extent that the change in value of a

95

derivative does not perfectly offset the change in value of the instrument being hedged. The unrealized gains and losses held in accumulated other comprehensive income will be reclassified to earnings over time as the hedged items are recognized in earnings. We have a policy of only entering into contracts with major financial institutions based upon their credit ratings and other factors.

We use standard market conventions to determine the fair values of derivative instruments, and techniques such as discounted cash flow analysis, option pricing models, and termination cost are used to determine fair value at each balance sheet date. All methods of assessing fair value result in a general approximation of value and such value may never actually be realized.

Accumulated Comprehensive Income

The components of our accumulated comprehensive income consisted of the following as of December 31:

|  | 2006 |  | 2005 |
--- | --- | --- | --- | --- | ---
Cumulative translation adjustment |  | $ | (1,475 | ) | $ | (2,811 | )
Accumulated derivative gains, net |  |  | 19,715 |  |  | 12,715 |
Net unrealized gains (losses) on marketable securities |  |  | 999 |  |  | (111 | )
Total accumulated comprehensive income |  | $ | 19,239 |  | $ | 9,793 |

Revenue Recognition

We, as a lessor, retain substantially all of the risks and benefits of ownership of the investment properties and account for our leases as operating leases. We accrue minimum rents on a straight-line basis over the terms of their respective leases. Substantially all of our retail tenants are also required to pay overage rents based on sales over a stated base amount during the lease year. We recognize overage rents only when each tenant's sales exceeds the applicable sales threshold.

We structure our leases to allow us to recover a significant portion of our property operating, real estate taxes, repairs and maintenance, and advertising and promotion expenses from our tenants. A substantial portion of our leases, other than those for anchor stores, require the tenant to reimburse us for a substantial portion of our operating expenses, including common area maintenance (CAM), real estate taxes and insurance. This significantly reduces our exposure to increases in costs and operating expenses resulting from inflation. For approximately 60% of our leases, we receive a fixed payment from the tenant for the CAM component, which is subject to an annual adjustment. We are continually working toward converting the remainder of our leases to the fixed payment methodology. Under these leases, CAM expense reimbursements are based on the tenant's proportionate share of the allocable operating expenses and CAM capital expenditures for the property. Such property operating expenses typically include utility, insurance, security, janitorial, landscaping, food court and other administrative expenses. We accrue reimbursements from tenants for recoverable portions of all these expenses as revenue in the period the applicable expenditures are incurred. We also receive escrow payments for these reimbursements from substantially all our non-fixed CAM tenants and monthly fixed CAM payments throughout the year. We do this to reduce the risk of loss on uncollectible accounts once we perform the final year-end billings for recoverable expenditures. We recognize differences between estimated recoveries and the final billed amounts in the subsequent year. These differences were not material in any period presented. Our advertising and promotional costs are expensed as incurred.

Management Fees and Other Revenues

Management fees and other revenues are generally received from our unconsolidated joint venture Properties as well as third parties. Management fee revenue is recognized based on a contractual percentage of joint venture

96

property revenue. Development fee revenue is recognized on a contractual percentage of hard costs to develop a property. Leasing fee revenue is recognized on a contractual per square foot charge based on the square footage of current year leasing activity.

Insurance premiums written and ceded are recognized on a pro-rata basis over the terms of the policies. Insurance losses are reflected in property operating expenses in the accompanying statements of operations and comprehensive income and include estimates for losses incurred but not reported as well as losses pending settlement. Estimates for losses are based on evaluations by actuaries and management's best estimates. Total insurance reserves for our insurance subsidiary as of December 31, 2006 and 2005 approximated $112.5 million and $93.6 million, respectively.

We recognize fee revenues from our co-branded gift card programs when the fees are earned under the related arrangements with the card issuer. Generally, these revenues are recorded at the issuance of the gift card for handling fees and, if applicable, at future dates for servicing fees.

Allowance for Credit Losses

We record a provision for credit losses based on our judgment of a tenant's creditworthiness, ability to pay and probability of collection. In addition, we also consider the retail sector in which the tenant operates and our historical collection experience in cases of bankruptcy, if applicable. Presented below is the activity in the allowance for credit losses and includes the activities related to discontinued operations during the following years:

|  | For the year Ended December 31, |
--- | --- | --- | ---
|  | 2006 |  | 2005 |  | 2004 |
Balance at Beginning of Year |  | $ | 35,239 |  | $ | 37,039 |  | $ | 31,473 |

Balance at End of Year |  | $ | 32,817 |  | $ | 35,239 |  | $ | 37,039 |

Income Taxes

Simon Property and certain other subsidiaries are taxed as REITs under Sections 856 through 860 of the Internal Revenue Code of 1986, as amended (the "Code") and applicable Treasury regulations relating to REIT qualification. In order to maintain this REIT status, the regulations require us to distribute at least 90% of our taxable income to stockholders and meet certain other asset and income tests as well as other requirements. We intend to continue to adhere to these requirements and maintain the REIT status of Simon Property and the REIT subsidiaries. As REITs, these entities will generally not be liable for federal corporate income taxes as long as they continue to distribute in excess of 100% of their taxable income. Thus, we made no provision for federal income taxes for these entities in the accompanying consolidated financial statements. If Simon Property or any of our REIT subsidiaries fail to qualify as a REIT, it will be subject to tax at regular corporate rates for the years in which it failed to qualify. If we lose our REIT status we could not elect to be taxed as a REIT for four years unless our failure to qualify was due to reasonable cause and certain other conditions were satisfied.

On October 22, 2004, President Bush signed the American Jobs Creation Act which included several provisions of the REIT Improvement Act, which builds in some flexibility to the REIT rules. This Act provides for monetary penalties in lieu of REIT disqualification. This better matches the severity of the penalty to the REIT's error and therefore reduces the possibility of disqualification.

97

State income, franchise or other taxes were not significant in any of the periods presented.

We have also elected taxable REIT subsidiary ("TRS") status for some of our subsidiaries. This enables us to provide services that would otherwise be considered impermissible for REITs and participate in activities that don't qualify as "rents from real property". For these entities, deferred tax assets and liabilities are established for temporary differences between the financial reporting basis and the tax basis of assets and liabilities at the enacted tax rates expected to be in effect when the temporary differences reverse. A valuation allowance for deferred tax assets is provided if we believe all or some portion of the deferred tax asset may not be realized. An increase or decrease in the valuation allowance that results from the change in circumstances that causes a change in our judgment about the realizability of the related deferred tax asset is included in income.

As of December 31, 2006 and 2005, we had a net deferred tax asset of $12.8 million and $7.1 million, respectively, related to our TRS subsidiaries. The net deferred tax asset is included in deferred costs and other assets in the accompanying consolidated balance sheets and consists primarily of operating losses and other carryforwards for Federal income tax purposes as well as the timing of the deductibility of losses or reserves from insurance subsidiaries.

Reclassifications

We made certain reclassifications of prior period amounts in the financial statements to conform to the 2006 presentation. These reclassifications have no impact on net income previously reported. The reclassifications principally related to the classification of certain expenses and inclusion of the Limited Partners' interest in the Operating Partnership and preferred distributions of the Operating Partnership in the determination of net income from continuing operations. Also, significant property dispositions during 2004 and 2005 have been reclassified in the statements of operations and comprehensive income for the periods ended December 31, 2004 and 2005.

4. Real Estate Acquisitions, Disposals, and Impairment

We acquire properties to generate both current income and long-term appreciation in value. We acquire individual properties or portfolios of other retail real estate companies that meet our investment criteria. We sell properties which no longer meet our strategic criteria. Our acquisition and disposal activity for the periods presented are highlighted as follows:

2006 Acquisitions

As described in Note 7, on February 13, 2006, we sold 10.5% of our ownership interests in Simon Ivanhoe S.à.r.l. ("Simon Ivanhoe") to our partner, Ivanhoe Cambridge, Inc. ("Ivanhoe"), and recognized a gain upon this transaction of $34.4 million. We then settled all remaining share purchase commitments from the company's founders, including the early settlement of some commitments by purchasing an additional 25.8% interest for €55.1 million, or $65.5 million. The result of these transactions equalized our and Ivanhoe's ownership in Simon Ivanhoe to 50% each.

On November 1, 2006, we acquired the remaining 50% interest in Mall of Georgia, a regional mall Property, from our partner for $252.6 million, including the assumption of our $96.0 million share of debt. As a result, we now own 100% of Mall of Georgia and the Property was consolidated as of the acquisition date.

2005 Acquisitions

On November 18, 2005, we purchased a 37.99% interest in Springfield Mall in Springfield, Pennsylvania, for approximately $39.3 million, including the issuance of our share of debt of $29.1 million. On November 21, 2005, we purchased a 50% interest in Coddingtown Mall in Santa Rosa, California, for approximately $37.1 million, including the assumption of our share of debt of $10.5 million. Both of these Properties are being accounted for on the equity method of accounting.

98

2004 Acquisitions

On February 5, 2004, we purchased a 95% interest in Gateway Shopping Center in Austin, Texas, for approximately $107.0 million. We initially funded this transaction with borrowings on our Credit Facility and with the issuance of 120,671 units of the Operating Partnership valued at approximately $6.0 million.

On April 1, 2004, we increased our ownership interest in The Mall of Georgia Crossing from 50% to 100% for approximately $26.3 million, including the assumption of $16.5 million of debt. As a result of this transaction, this Property is now reported as a consolidated entity.

On April 27, 2004, we increased our ownership in Bangor Mall in Bangor, Maine from 32.6% to 67.6% and increased our ownership in Montgomery Mall in Montgomery, Pennsylvania from 23.1% to 54.4%. We acquired these additional ownership interests from our partner in the properties for approximately $67.0 million and the assumption of $16.8 million of debt. We funded this transaction with a mortgage and borrowings on our Credit Facility. Bangor Mall and Montgomery Mall were previously accounted for under the equity method. These Properties are now consolidated as a result of this acquisition.

On May 4, 2004, we purchased a 100% interest in Plaza Carolina in San Juan, Puerto Rico for approximately $309.0 million. We funded this transaction with a mortgage and borrowings on our Credit Facility.

On November 19, 2004, we increased our ownership interest in Lehigh Valley Mall, located in Whitehall, Pennsylvania, from 24.88% to 37.61% for approximately $42.3 million, including the assumption of our $25.9 million share of debt.

On December 15, 2004, we increased our ownership in Woodland Hills in Tulsa, Oklahoma from 47.2% to 94.5%. We acquired this additional ownership interest from our partner in the property for approximately $119.5 million, including the assumption of $39.7 million of debt. Woodland Hills was previously accounted for under the equity method. This Property is now consolidated as a result of this acquisition.

Chelsea Acquisition

On October 14, 2004, we acquired all of the outstanding common stock of Chelsea Property Group, Inc. ("Chelsea") and the limited partnership units of its operating partnership subsidiary in a transaction valued at approximately $5.2 billion, including the assumption of $1.5 billion of debt (the "Chelsea Acquisition"). Chelsea had interests in 37 Premium Outlet centers and 24 other shopping centers containing 16.6 million square feet of gross leasable area in 31 states, Japan and Mexico. We funded the cash portion of this acquisition with a $1.8 billion unsecured term loan facility discussed in Note 8. Chelsea common stockholders received consideration of $36.00 per share for each share of Chelsea's common stock in cash, a fractional share of 0.2936 of our common stock, and a fractional share of 0.3000 of Simon 6% Series I convertible perpetual preferred stock. The holders of Chelsea's operating partnership subsidiary's limited partnership common units exchanged their units for common and convertible preferred units of the Operating Partnership. The following shares and units were issued at closing:

•
  12,978,795 shares of common stock
•
  4,652,232 Operating Partnership common units
•
  13,261,712 shares of Simon Property 6% Series I Convertible Perpetual Preferred Stock (liquidation value of $50 per share)
•
  4,753,794 Operating Partnership 6% Convertible Perpetual Preferred Units (liquidation value of $50 per unit)

During 2005, we finalized the purchase price allocation for the Chelsea Acquisition as required by FAS 141, as described in our purchase accounting allocation policy in Note 3. Our valuation of the Chelsea assets was developed in consultation with independent valuation specialists. The final purchase price allocation reflects reallocations between

99

tangible assets and finite life intangible assets. However, these adjustments did not have a significant impact on our consolidated results of operations.

The following unaudited pro forma condensed consolidated statements of operations for the year ended December 31, 2004 includes adjustments for the Chelsea Acquisition as if the transaction had occurred as of January 1, 2004. The pro forma information does not purport to present what actual results would have been had this acquisition, and the related transaction, in fact, occurred at the previously mentioned date, or to project results for any future period. Our other acquisitions during the periods presented were not considered material business combinations for the purpose of presenting this pro forma financial information.

2006 Disposals

During the year ended December 31, 2006, we disposed of three consolidated properties and one property in which we held a 50% interest and accounted for under the equity method. We received net proceeds of $52.7 million and recorded our share of a gain on the disposals totaling $12.2 million.

2005 Disposals

During the year ended December 31, 2005, we sold or disposed of sixteen non-core properties, consisting of four regional malls, one community/lifestyle center, nine other outlet centers and two office buildings. Our significant dispositions are summarized as follows (dollars in millions):

Properties |  | Previous Ownership % |  | Date of Disposal |  | Sales Price |  | Gain/(Loss) |
--- | --- | --- | --- | --- | --- | --- | --- | --- | ---
Riverway and O'Hare International Center |  | 100% |  | June 1, 2005 |  | $ | 257.3 |  | $ | 125.1 |
Grove at Lakeland Square |  | 100% |  | July 1, 2005 |  |  | 10.4 |  |  | (0.1 | )

Less: Limited Partners' Interest |  |  |  |  |  |  |  |  |  | 31.1 |
|  |  |  |  |  |  |  |  | $ | 115.8 |

100

The disposition of Biltmore Square was accomplished through a transfer of the deed to the property to the lender in settlement of the remaining balance of the non-recourse debt on the property. Additionally, nine other insignificant non-core properties were sold which resulted in no gain or loss.

We disposed of two joint venture properties during 2005. On January 11, 2005, Metrocenter was sold for $62.6 million and we recognized our share of the gain of $11.8 million. On December 22, 2005, our Canadian property, Forum Entertainment Centre, was sold and we recognized our share of the loss of $13.7 million.

Certain of the net proceeds from these sales, net of repayment of outstanding debt, were held in escrow to complete IRS Section 1031 exchanges while the remainder was used for general working capital purposes.

2004 Disposals

During the year ended December 31, 2004, we sold five non-core properties, consisting of three regional malls, one community/lifestyle center and one Premium Outlet center. The significant properties and their dates of sale consisted of:

Properties |  | Previous Ownership % |  | Date of Disposal |  | Sales Price |  | Gain/(Loss) |
--- | --- | --- | --- | --- | --- | --- | --- | --- | ---
Hutchinson Mall |  | 100% |  | June 15, 2004 |  | $ | 16.3 |  | $ | 0.2 |

Less: Limited Partners' Interest |  |  |  |  |  |  |  |  |  | 0.1 |
|  |  |  |  |  |  |  |  | $ | (0.3 | )

We disposed of three joint venture properties during 2004. On April 7, 2004, we sold a joint venture interest in a hotel for $17.0 million, resulting in a gain of $12.6 million, $8.3 million net of tax. On April 8, 2004, we sold our joint venture interest in Yards Plaza resulting in no gain or loss on this disposition. On August 6, 2004, we completed the court ordered sale of our joint venture interest in Mall of America (see Note 11).

Impairment. In 2004, we recorded an $18.0 million impairment charge related to one Property. We evaluate our Properties for impairment using a combination of estimations of the fair value based upon a multiple of the net cash flow of the Properties and discounted cash flows from the individual Properties' operations as well as contract prices, if applicable and available.

5. Per Share Data

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

101

reconciliation below represent the common stockholders' pro rata share of the respective line items in the statements of operations and is after considering the effect of preferred dividends.

|  | For the Year ended December 31,
--- | --- | ---
|  | 2006 |  | 2005 |  | 2004
Common Stockholders' share of: |  |  |  |  |  |  |  |  |
Net Income available to Common Stockholders — Basic |  | $ | 486,145 |  | $ | 401,895 |  | $ | 300,647

Impact to General Partner's interest in Operating Partnership from all dilutive securities and options |  |  | 415 |  |  | 337 |  |  | 279
Net Income available to Common Stockholders — Diluted |  | $ | 486,560 |  | $ | 402,232 |  | $ | 300,926
Weighted Average Shares Outstanding — Basic |  |  | 221,024,096 |  |  | 220,259,480 |  |  | 207,989,585

Weighted Average Shares Outstanding — Diluted |  |  | 221,927,351 |  |  | 221,130,490 |  |  | 208,856,953

For the year ending December 31, 2006, potentially dilutive securities include stock options, certain preferred units of limited partnership interest of the Operating Partnership, certain contingently convertible preferred stock and the units of limited partnership interest ("Units") in the Operating Partnership which are exchangeable for common stock. The only potentially dilutive security that had a dilutive effect for the year ended December 31, 2006, 2005 and 2004 were stock options.

We accrue distributions when they are declared. The taxable nature of the dividends declared for each of the years ended as indicated is summarized as follows:

|  | For the Year Ended December 31, |
--- | --- | --- | ---
|  | 2006 |  | 2005 |  | 2004 |

7. Investments in Unconsolidated Entities

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. We held joint venture ownership interests in 68 Properties as of December 31, 2006 and 69 as of December 31, 2005. We also held interests in two joint ventures which owned 53 European shopping centers as of December 31, 2006 and 51 as of December 31, 2005. 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 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 will result in either the sale of our interest or the use of available cash or borrowings to acquire the joint venture interest.

On May 10, 2006, we refinanced thirteen cross-collateralized mortgages with seven individual secured loans totaling $796.6 million with fixed rates ranging from 5.79% to 5.83%. The balance of the previous mortgages totaled $625.0 million, and bore interest at rates ranging from LIBOR plus 41 basis points to a fixed rate of 8.28%, and was scheduled to mature on May 15, 2006. We received our share of excess refinanced proceeds of approximately $86 million on the closing of the new mortgage loan.

On November 1, 2006, we acquired the remaining 50% interest in Mall of Georgia, a regional mall Property, from our partner for $252.6 million, including the assumption of our $96.0 million share of debt. As a result, we now own 100% of Mall of Georgia and the property was consolidated as of the acquisition date. We have reclassified the results of this property in the Joint Venture Statement of Operations into "Consolidated Joint Venture Interests."

During 2005, we and our joint venture partner completed the construction of, obtained permanent financing for, and opened St. Johns Town Center (St. Johns). Prior to the completion of construction and opening of the center, we were responsible for 85% of the development costs, and guaranteed this same percentage of the outstanding construction debt. As a result, we consolidated St. Johns during its construction phase. Upon obtaining permanent financing, the guarantee was released, and our partner's and our ownership percentages were each adjusted to 50%. We received a distribution from the partnership of $15.7 million in repayment of our capital contributions to equalize our ownership interests, and this Property is now accounted for using the equity method of accounting.

On June 1, 2005, we refinanced Westchester Mall, a joint venture Property, with a $500.0 million, 4.86% fixed-rate mortgage that matures on June 1, 2010. The balances of the two previous mortgages, which were repaid,

103

were $142.0 million and $50.1 million and bore interest at fixed rates of 8.74% and 7.20%, respectively. Both were scheduled to mature on September 1, 2005. We received our share of the excess refinancing proceeds of approximately $120.0 million on the closing of the new mortgage loan.

On November 29, 2005, we refinanced Houston Galleria, a joint venture Property, with a $821.0 million, 5.436% fixed-rate mortgage that matures on December 1, 2015. The balances of the two previous mortgages, which were repaid, were $213.2 million and $84.7 million and bore interest at a fixed rate of 7.93% and at LIBOR plus 150 basis points, respectively. They were scheduled to mature on December 1, 2005 and December 31, 2006, respectively. We received our share of the excess refinancing proceeds of approximately $165.0 million on the closing of the new mortgage loan.

On December 28, 2005, we invested $50.0 million of equity for a 40% interest in a joint venture with Toll Brothers, Inc. (Toll Brothers) and Meritage Homes Corp. (Meritage Homes) to purchase a 5,485-acre land parcel in northwest Phoenix from DaimlerChrysler Corporation for $312 million. Toll Brothers and Meritage Homes each plan to build a significant number of homes on the site. We have the option to purchase a substantial portion of the commercial property for retail uses. Other parcels may also be sold to third parties. The site plans call for a mixed-use master planned community, which will include approximately 4,840 acres of single-family homes and attached homes. Approximately 645 acres of commercial and retail development will include schools, community amenities and open space. The entitlement, planning, and design processes are ongoing and initial home sales are tentatively scheduled to begin in 2009. The joint venture, of which Toll Brothers is the managing member, expects to develop a master planned community of approximately 12,000 to 15,000 residential units.

Summary financial information of the joint ventures 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 or became the primary beneficiary and as a result, gain unilateral control of the Property. We reclassified these line items into "Discontinued Joint Venture Interests" and "Consolidated Joint Venture Interests" so that we may present comparative results of operations for those joint venture interests held as of December 31, 2006. Balance sheet information as of December 31 is as follows:

On January 11, 2005, Metrocenter, a joint venture regional mall property was sold. We recognized our share of the gain of $11.8 million, net of the write-off of the related investment and received $62.6 million representing our share of the proceeds from this disposition. On December 22, 2005, The Forum Entertainment Centre, our Canadian property, was sold. We recognized our share of the loss of $13.7 million, net of the write-off of the related investment, from the disposition of this property. The result of these two dispositions is included in the loss on sales of interests in unconsolidated entities and other assets, net in the 2005 consolidated statements of operations and comprehensive income. On April 25, 2006, Great Northeast Plaza, a joint venture community center was sold. We recognized our share of the gain of $7.7 million, net of the write-off of the related investment and received $8.8 million representing our share of the proceeds from this disposition.

Our share of the net gain resulting from the sale of Metrocenter, The Forum Entertainment Centre, and Great Northeast Plaza are shown separately in "gain on sales of assets and interests in unconsolidated entities, net" in the consolidated statement of operations.

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 $338.1 million and $287.4 million as of December 31, 2006 and 2005, 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 December 31, 2006.

On October 20, 2005, Ivanhoe Cambridge, Inc. ("Ivanhoe"), an affiliate of Caisse de dépôt et placement du Québec, effectively acquired our former partner's 39.5% ownership interest in Simon Ivanhoe. On February 13, 2006, pursuant to the terms of our October 20, 2005 transaction with Ivanhoe, we sold a 10.5% interest in this joint venture to Ivanhoe for €45.2 million, or $53.9 million, and recorded a gain on the disposition of $34.4 million. This gain is reported in "gain on sales of interests in unconsolidated entities, net" in the consolidated statements of operations. We then settled all remaining share purchase commitments from the company's founders, including the early settlement of some commitments by purchasing an additional 25.8% interest in Simon Ivanhoe for €55.1 million, or $65.5 million. These transactions equalized our and Ivanhoe's ownership in Simon Ivanhoe to 50% each.

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 $281.2 million and $287.7 million as of December 31, 2006 and 2005, respectively, net of the related cumulative translation adjustments. We have a 40% ownership in these Japan Premium Outlet joint ventures. We also began construction on our first Premium Outlet in South Korea. As of December 31, 2006, our investment in our Premium Outlet in South Korea, for which we hold a 50% ownership interest, approximated $18.5 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 $60 million. We account for our investments in GMI under the equity method of accounting. As of December 31, 2006, our combined investment in these shopping centers in GMI is approximately $15.9 million.

General. At December 31, 2006, we have pledged 80 Properties as collateral to secure related mortgage notes including 8 pools of cross-defaulted and cross-collateralized mortgages encumbering a total of 42 Properties. Under these cross-default provisions, a default under any mortgage included in the cross-defaulted package may constitute a default under all such mortgages and may lead to acceleration of the indebtedness due on each Property within the collateral package. Of our 80 encumbered Properties, indebtedness of 20 of these encumbered Properties and our unsecured notes are subject to various financial performance covenants relating to leverage ratios, annual real property appraisal requirements, debt service coverage ratios, minimum net worth ratios, debt-to-market capitalization, and/or minimum equity values. Our mortgages and other indebtedness may be prepaid but are generally subject to prepayment of a yield-maintenance premium or defeasance. As of December 31, 2006, we are in compliance with all our debt covenants.

Some of the limited partner Unitholders guarantee a portion of our consolidated debt through foreclosure guarantees. In total, 53 limited partner Unitholders provide guarantees of foreclosure of $447.3 million of our consolidated debt at 12 consolidated Properties. In each case, the loans were made by unrelated third party institutional lenders and the guarantees are for the benefit of each lender. In the event of foreclosure of the mortgaged property, the proceeds from the sale of the property are first applied against the amount of the guarantee and also reduce the amount payable under the guarantee. To the extent the sale proceeds from the disposal of the property do not cover the amount of the guarantee, then the Unitholder is liable to pay the difference between the sale proceeds and the amount of the guarantee so that the entire amount guaranteed to the lender is satisfied. The debt is non-recourse to us and our affiliates.

108

Unsecured Debt

We have $1.0 billion of unsecured notes issued by our subsidiaries that are structurally senior in right of payment to holders of other unsecured notes to the extent of the assets and related cash flows of certain Properties. These unsecured notes have a weighted average interest rate of 7.02% and weighted average maturities of 5.3 years.

On March 31, 2006, Standard & Poor's Rating Services raised its corporate credit rating for us to 'A-' from 'BBB+' which resulted in a decrease in the interest rate applicable to borrowings on our unsecured revolving $3 billion credit facility (the "Credit Facility") to 37.5 basis points over LIBOR from 42.5 basis points over LIBOR. The revision to our rating also decreased the facility fee on our Credit Facility to 12.5 basis points from 15 basis points.

On May 15, 2006, we issued two tranches of senior unsecured notes totaling $800 million at a weighted average fixed interest rate of 5.93%. The first tranche is $400.0 million at a fixed interest rate of 5.75% due May 1, 2012 and the second tranche is $400.0 million at a fixed interest rate of 6.10% due May 1, 2016. We used the proceeds of the offering and the termination of forward-starting swap arrangements to reduce borrowings on our Credit Facility.

On August 29, 2006, we issued two tranches of senior unsecured notes totaling $1.1 billion at a weighted average fixed interest rate of 5.73%. The first tranche is $600.0 million at a fixed interest rate of 5.60% due September 1, 2011 and the second tranche is $500.0 million at a fixed interest rate of 5.875% due March 1, 2017. We used proceeds from the offering to reduce borrowings on our Credit Facility.

On December 12, 2006, we issued two tranches of senior unsecured notes totaling $1.25 billion at a weighted average fixed interest rate of 5.13%. The first tranche is $600.0 million at a fixed interest rate of 5.00% due March 1, 2012 and the second tranche is $650.0 million at a fixed interest rate of 5.25% due December 1, 2016. We used proceeds from the offering to reduce borrowings on our Credit Facility and reinvested the remainder of the proceeds of approximately $577.4 million to be used for general working capital purposes.

Credit Facility. Other significant draws on our Credit Facility during the twelve-month period ended December 31, 2006 were as follows:

Draw Date |  | Draw Amount |  | Use of Credit Line Proceeds
--- | --- | --- | --- | ---
01/03/06 |  | $ | 59,075 |  | Repayment of a Term Loan (CPG Partners, L.P.), which had a rate of 7.26%.
01/06/06 |  |  | 140,000 |  | Repayment of a mortgage, which had a rate of LIBOR plus 137.5 basis points.
01/20/06 |  |  | 300,000 |  | Repayment of unsecured notes, which had a fixed rate of 7.375%.
03/27/06 |  |  | 600,000 |  | Early repayment of the $1.8 billion facility we used to finance our acquisition of Chelsea in 2004.
04/03/06 |  |  | 58,000 |  | Repayment of two secured mortgages which each bore interest at 8.25%.
11/01/06 |  |  | 200,000 |  | Repayment of the preferred stock issued to fund the redemption of our Series F Preferred Stock.
11/15/06 |  |  | 250,000 |  | Repayment of unsecured notes, which had a fixed rate of 6.875%.

Other amounts drawn on our Credit Facility were primarily for general working capital purposes. We repaid a total of $2.8 billion on our Credit Facility during the year ended December 31, 2006. The total outstanding balance on our Credit Facility as of December 31, 2006 was $305.1 million, and the maximum amount outstanding during the year was approximately $2.0 billion. During the year ended December 31, 2006, the weighted average outstanding balance on our Credit Facility was approximately $1.1 billion.

Acquisition Facility. We borrowed $1.8 billion in 2004 to finance the cash portion of our acquisition of Chelsea. As disclosed above, this facility has been fully repaid.

109

Secured Debt

Mortgages and Other Indebtedness. The balance of fixed and variable rate mortgage notes was $4.4 billion and $4.6 billion as of December 31, 2006 and 2005, respectively, including related premiums. Of the 2006 amount, $4.3 billion is nonrecourse to us. The fixed-rate mortgages generally require monthly payments of principal and/or interest. The interest rates of variable-rate mortgages are typically based on LIBOR. During the twelve-month period ended December 31, 2006, we repaid $275.8 million in mortgage loans, unencumbering four properties.

As a result of the acquisition of our partner's 50% ownership interest in Mall of Georgia on November 1, 2006, we now own 100% of the mall and the Property was consolidated as of the acquisition date. This included the consolidation of the Property's $192.0 million 7.09% fixed-rate mortgage.

Debt Maturity and Other

Our scheduled principal repayments on indebtedness as of December 31, 2006 are as follows:

2007 |  | $ | 1,683,966
2008 |  |  | 809,667
2009 |  |  | 1,653,486
2010 |  |  | 2,001,021
2011 |  |  | 2,309,420
Thereafter |  |  | 6,882,596
Total principal maturities |  |  | 15,340,156
Net unamortized debt premium and other |  |  | 54,333
Total mortgages and other indebtedness |  | $ | 15,394,489

Our cash paid for interest in each period, net of any amounts capitalized, was as follows:

|  | For the year ended December 31,
--- | --- | ---
|  | 2006 |  | 2005 |  | 2004
Cash paid for interest |  | $ | 845,964 |  | $ | 822,906 |  | $ | 648,984

Derivative Financial Instruments

Our exposure to market risk due to changes in interest rates primarily relates to our long-term debt obligations. We manage exposure to interest rate market risk through our risk management strategy by a combination of interest rate protection agreements to effectively fix or cap a portion of variable rate debt, or in the case of a fair value hedge, effectively convert fixed rate debt to variable rate debt. We are also exposed to foreign currency risk on financings of certain foreign operations. Our intent is to offset gains and losses that occur on the underlying exposures, with gains and losses on the derivative contracts hedging these exposures. We do not enter into either interest rate protection or foreign currency rate protection agreements for speculative purposes.

We may enter into treasury lock agreements as part of an anticipated debt issuance. If the anticipated transaction does not occur, the cost is charged to net income. Upon completion of the debt issuance, the cost of these instruments is recorded as part of accumulated other comprehensive income and is amortized to interest expense over the life of the debt agreement.

As of December 31, 2006, we have reflected the fair value of outstanding consolidated derivatives in other liabilities for $9.4 million. In addition, we recorded the benefits from our treasury lock and interest rate hedge agreements in accumulated comprehensive income and the unamortized balance of these agreements is $5.7 million as

110

of December 31, 2006. The net benefits from terminated swap agreements are also recorded in accumulated comprehensive income and the unamortized balance is $12.2 million as of December 31, 2006. As of December 31, 2006, our outstanding LIBOR based derivative contracts consist of:

•
  interest rate cap protection agreements with a notional amount of $95.7 million that mature in May 2007.
•
  variable rate swap agreements with a notional amount of $370.0 million that mature in September 2008 and January 2009 and have a weighted average pay rate of 5.36% and a weighted average receive rate of 3.72%.

Within the next twelve months, we expect to reclassify to earnings approximately $4.3 million of income of the current balance held in accumulated other comprehensive income. The amount of ineffectiveness relating to fair value and cash flow hedges recognized in income during the periods presented was not material.

Fair Value of Financial Instruments

The carrying value of our variable-rate mortgages and other loans approximates their fair values. We estimated the fair values of combined fixed-rate mortgages using cash flows discounted at current borrowing rates and other indebtedness using cash flows discounted at current market rates. The fair values of financial instruments and our related discount rate assumptions used in the estimation of fair value for our consolidated fixed-rate mortgages and other indebtedness as of December 31 is summarized as follows:

|  | 2006 |  | 2005 |
--- | --- | --- | --- | --- | ---
Fair value of fixed-rate mortgages and other indebtedness |  | $ | 14,479,171 |  | $ | 12,078,531 |
Average discount rates assumed in calculation of fair value |  |  | 6.53 | % |  | 6.11 | %

9. Rentals under Operating Leases

Future minimum rentals to be received under noncancelable tenant operating leases for each of the next five years and thereafter, excluding tenant reimbursements of operating expenses and percentage rent based on tenant sales volume as of December 31, 2006 are as follows:

2007 |  | $ | 1,619,178
2008 |  |  | 1,491,243
2009 |  |  | 1,339,472
2010 |  |  | 1,163,250
2011 |  |  | 976,740
Thereafter |  |  | 2,921,770
|  | $ | 9,511,653

Approximately 0.8% of future minimum rents to be received are attributable to leases with an affiliate of a limited partner in the Operating Partnership.

10. Capital Stock

The Board of Directors ("Board") is authorized to reclassify the excess common stock into one or more additional classes and series of capital stock, to establish the number of shares in each class or series and to fix the preferences, conversion and other rights, voting powers, restrictions, limitations as to dividends, and qualifications and terms and conditions of redemption of such class or series, without any further vote or action by the stockholders. The issuance of additional classes or series of capital stock may have the effect of delaying, deferring or preventing a change in control of Simon Property without further action of the stockholders. The ability of the Board to issue

111

additional classes or series of capital stock, while providing flexibility in connection with possible acquisitions and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or of discouraging a third party from acquiring, a majority of the outstanding voting stock of Simon Property.

The holders of common stock of Simon Property are entitled to one vote for each share held of record on all matters submitted to a vote of stockholders, other than for the election of directors. At the time of the initial public offering of Simon Property's predecessor in 1993, the charter of the predecessor gave Melvin Simon, Herbert Simon, David Simon and certain of their affiliates (the "Simons") the right to elect four of the thirteen members of the Board, conditioned upon the Simons, or entities they control, maintaining specified levels of equity ownership in Simon Property's predecessor, the Operating Partnership and all of their subsidiaries. In addition, at that time, Melvin Simon & Associates, Inc. ("MSA"), acquired 3,200,000 shares of Class B common stock. MSA placed the Class B common stock into a voting trust under which the Simons were the sole trustees. These voting trustees had the authority to elect the four members of the Board. These same arrangements were incorporated into Simon Property's Charter in 1998 during the combination of its predecessor and Corporate Property Investors, Inc. Shares of Class B common stock convert automatically into an equal number of shares of common stock upon the sale or transfer thereof to a person not affiliated with Melvin Simon, Herbert Simon or David Simon. The holder of the Class C common stock (the "DeBartolos") is entitled to elect two of the thirteen members of the Board. Shares of Class C common stock convert automatically into an equal number of shares of common stock upon the sale or transfer thereof to a person not affiliated with the members of the DeBartolo family or entities controlled by them. The Class B and Class C shares can be converted into shares of common stock at the option of the holders. At the initial offering we reserved 3,200,000 and 4,000 shares of common stock for the possible conversion of the outstanding Class B and Class C shares, respectively.

On March 1, 2004, Simon Property and the Simons completed a restructuring transaction in which MSA exchanged 3,192,000 Class B common shares for an equal number of shares of common stock in accordance with our Charter. Those shares continue to be owned by MSA and remain subject to a voting trust under which the Simons are the sole voting trustees. MSA exchanged the remaining 8,000 Class B common shares with David Simon for 8,000 shares of common stock and David Simon's agreement to create a new voting trust under which the Simons as voting trustees, hold and vote the remaining 8,000 shares of Class B common stock acquired by David Simon. As a result, these voting trustees have the authority to elect four of the members of the Board contingent on the Simons maintaining specified levels of equity ownership in Simon Property, the Operating Partnership and their subsidiaries.

Common Stock Issuances and Repurchases

In 2006, we issued 86,800 shares of common stock to five limited partners in exchange for an equal number of Units.

We issued 414,659 shares of common stock related to employee and director stock options exercised during 2006. We used the net proceeds from the option exercises of approximately $14.9 million to acquire additional units of the Operating Partnership. The Operating Partnership used the net proceeds for general working capital purposes.

On May 12, 2006, the Board authorized the repurchase of up to 6,000,000 shares of our common stock subject to a maximum aggregate purchase price of $250 million over the next twelve months as market conditions warrant.

Dividends on all series of preferred stock are calculated based upon the preferred stock's preferred return multiplied by the preferred stock's corresponding liquidation value. The Operating Partnership pays preferred distributions to Simon Property equal to the dividends paid on the preferred stock issued.

Series B Convertible Preferred Stock. During 2003, all of the outstanding shares of our 6.5% Series B Convertible Preferred Stock were either converted into shares of common stock or were redeemed at a redemption price of $106.34 per share. We issued an aggregate of 1,628,400 shares of common stock to the holders who exercised their conversion rights. The remaining 18,340 shares of Series B preferred stock were redeemed with cash from the proceeds of the private issuance of a new series of preferred stock (Series H).

On August 27, 1999, Simon Property authorized these two new series of preferred stock to be available for issuance upon conversion by the holders or redemption by the Operating Partnership of the 7.00% Preferred Units or the 8.00% Preferred Units, described below. Each of these new series of preferred stock had terms that were substantially identical to the respective series of Preferred Units.

Effective October 4, 2006, we redeemed all 8,000,000 shares of our Series F Preferred Stock at a liquidation preference of $25.00 per share plus accrued dividends. Funds to redeem the Series F Preferred Stock were obtained through the issuance of a new series of preferred stock issued in a private transaction (Series K). These preferred shares were subsequently repurchased prior to year end at par value with borrowings from our Credit Facility. We recorded a $7.0 million charge to net income during the fourth quarter of 2006 related to the redemption of the Series F Preferred Stock.

On or after October 14, 2009, we shall have the option to redeem the 6% Convertible Perpetual Preferred Stock, in whole or in part, for shares of common stock only at a liquidation preference of $50.00 per share plus accumulated and unpaid dividends. However, if the redemption date falls between the record date and dividend payment date the redemption price will be equal to only the liquidation preference per share, and will not include any amount of dividends declared and payable on the corresponding dividend payment date. The redemption may occur only if, for 20 trading days within a period of 30 consecutive trading days ending on the trading day before notice of redemption is issued, the closing price per share of common stock exceeds 130% of the applicable conversion price. The 6% Convertible Perpetual Preferred Stock shall be convertible into a number of fully paid and non-assessable common shares upon the occurrence of a conversion triggering event. A conversion triggering event includes the following: (a) if the 6% Convertible Perpetual Preferred Share is called for redemption by us; or, (b) if we are a party to a consolidation, merger, binding share exchange, or sale of all or substantially all of our assets; or, (c) if during any fiscal quarter after the fiscal quarter ending December 31, 2004, the closing sale price of the common stock for at least 20 trading days in a period of 30 consecutive trading days ending on the last trading day of the preceding fiscal quarter exceeds 125% of the applicable conversion price.

7.75%/8.00% Cumulative Redeemable Preferred Units. During 2003, in connection with the purchase of additional interest in certain Properties, the Operating Partnership issued 7.75%/8.00% Cumulative Redeemable Preferred Units (the "7.75% Preferred Units") that accrue cumulative dividends at a rate of 7.75% of the liquidation value for the period beginning December 5, 2003 and ending December 31, 2004, 8.00% of the liquidation value for the period beginning January 1, 2005 and ending December 31, 2009, 10.00% of the liquidation value for the period beginning

115

January 1, 2010 and ending December 31, 2010, and 12% of the liquidation value thereafter. These dividends are payable quarterly in arrears. A unitholder may require the Operating Partnership to repurchase the 7.75% Preferred Units on or after January 1, 2009, or any time the aggregate liquidation value of the outstanding units exceeds 10% of the book value of partners' equity of the Operating Partnership. The Operating Partnership may redeem the 7.75% Preferred Units on or after January 1, 2011, or earlier upon the occurrence of certain tax triggering events. Our intent is to redeem these units after January 1, 2009, after the occurrence of a tax triggering event. The redemption price is the liquidation value plus accrued and unpaid distributions, payable in cash or interest in one or more properties mutually agreed upon.

7.5% Cumulative Redeemable Preferred Units. The Operating Partnership issued 7.5% Cumulative Redeemable Preferred Units (the "7.5% Preferred Units") in connection with the purchase of additional interest in Kravco. The 7.5% Preferred Units accrue cumulative dividends at a rate of $7.50 annually, which is payable quarterly in arrears. The Operating Partnership may redeem the 7.5% Preferred Units on or after November 10, 2013, unless there is the occurrence of certain tax triggering events such as death of the initial unitholder, or the transfer of any units to any person or entity other than the persons or entities entitled to the benefits of the original holder. The 7.5% Preferred Units' redemption price is the liquidation value plus accrued and unpaid distributions, payable either in cash or shares of common stock. In the event of the death of a holder of the 7.5% Preferred Units, the occurrence of certain tax triggering events applicable to the holder, or on or after November 10, 2006, the Preferred unitholder may require the Operating Partnership to redeem the 7.5% Preferred Units payable at the option of the Operating Partnership in either cash or shares of common stock.

7.00% Cumulative Convertible Preferred Units.

Notes Receivable from Former CPI Stockholders. Notes receivable of $17,261 from former Corporate Property Investors, Inc. ("CPI") stockholders, which result from securities issued under CPI's executive compensation program and were assumed in our merger with CPI, are reflected as a deduction from capital in excess of par value in the consolidated statements of stockholders' equity in the accompanying financial statements. The notes do not bear interest and become due at the time the underlying shares are sold.

The Simon Property Group 1998 Stock Incentive Plan. We have a stock incentive plan (the "1998 Plan"), which provides for the grant of equity-based awards during a ten-year period, in the form of options to purchase shares ("Options"), stock appreciation rights ("SARs"), restricted stock grants and performance unit awards (collectively, "Awards"). Options may be granted which are qualified as "incentive stock options" within the meaning of Section 422 of the Code and Options which are not so qualified. An aggregate of 11,300,000 shares of common stock have been reserved for issuance under the 1998 Plan. Additionally, the partnership agreement requires us to sell shares to the Operating Partnership, at fair value, sufficient to satisfy the exercising of stock options, and for us to purchase Units for cash in an amount equal to the fair market value of such shares.

Administration. The 1998 Plan is administered by Simon Property's Compensation Committee (the "Committee"). The Committee, at its sole discretion, determines which eligible individuals may participate and the type, extent and terms of the Awards to be granted to them. In addition, the Committee interprets the 1998 Plan and makes all other determinations deemed advisable for the administration of the 1998 Plan. Options granted to employees ("Employee Options") become exercisable over the period determined by the Committee. The exercise price of an Employee Option may not be less than the fair market value of the shares on the date of grant. Employee Options generally vest over a three-year period and expire ten years from the date of grant. We have not granted Employee Options, except for a series of reload options as part of a prior business combination, since 2001.

Automatic Awards For Eligible Directors. Prior to May 7, 2003, the 1998 Plan provided for automatic grants of Options to directors ("Director Options") of Simon Property who are not also our employees or employees of our affiliates ("Eligible Directors"). Each Eligible Director was automatically granted Director Options to purchase 5,000 shares upon the director's initial election to the Board, and upon each re-election, an additional 3,000 Director Options multiplied by the number of calendar years that had elapsed since such person's last election to the Board. The exercise price of Director Options is equal to the fair market value of the shares on the date of grant. Director Options vest and become exercisable on the first anniversary of the date of grant or in the event of a "Change in Control" as defined in the 1998 Plan. The last year during which Eligible Directors received awards of Director Options was 2002.

Pursuant to an amendment to the 1998 Plan approved by the stockholders effective May 7, 2003, Eligible Directors received annual grants of restricted stock in lieu of Director Options. Each Eligible Director received on the first day of the first calendar month following his or her initial election as a director, a grant of 1,000 shares of restricted stock annually. Thereafter, as of the date of each annual meeting of Simon Property's stockholders, Eligible Directors who were re-elected as directors received a grant of 1,000 shares of restricted stock. In addition, Eligible Directors who served as chairpersons of the standing committees of the Board received an additional annual grant in the amount of 500 shares of restricted stock (in the case of the Audit Committee) or 300 shares of restricted stock (in the case of all other standing committees).

Each award of restricted stock issued prior to May 11, 2006 vested in four equal annual installments on January 1 of each year, beginning in the year following the year in which the award occurred. If a director otherwise ceased to serve as a director before vesting, the unvested portion of the award terminated. Any unvested portion of a restricted stock award vested if the director died or became disabled while in office or has served a minimum of five annual terms as a director, but only if the Compensation Committee or full Board determines that such vesting is appropriate. The restricted stock also vested in the event of a "Change in Control."

117

Pursuant to an amendment to the 1998 plan approved by the stockholders effective May 11, 2006, each Eligible Director will receive on the first day of the first calendar month following his or her initial election as a director, an award of restricted stock with a value of $82,500 (pro-rated for partial years of service). Thereafter, as of the date of each annual meeting of the Company's stockholders, Eligible Directors who are re-elected as directors will receive an award of restricted stock having a value of $82,500. In addition, Eligible Directors who serve as chairpersons of the standing committees of the Board of Directors (excluding the Executive Committee) will receive an additional annual award of restricted stock having a value of $10,000 (in the case of the Audit Committee) or $7,500 (in the case of all other standing committees). The Lead Director will also receive an annual restricted stock award having a value of $12,500. The restricted stock will vest in full after one year.

Once vested, the delivery of any shares with respect to a restricted stock award (including reinvested dividends) is deferred under our Director Deferred Compensation Plan until the director retires, dies or becomes disabled or otherwise no longer serves as a director. The Eligible Directors may vote and are entitled to receive dividends on the shares underlying the restricted stock awards; however, any dividends on the shares underlying restricted stock awards must be reinvested in shares and held in the Director Deferred Compensation Plan until the shares underlying a restricted stock award are delivered to the former director.

In addition to automatic awards, Eligible Directors may be granted discretionary awards under the 1998 Plan.

Restricted Stock. The 1998 Plan also provides for shares of restricted common stock of Simon Property to be granted to certain employees at no cost to those employees, subject to achievement of certain financial and return-based performance measures established by the Compensation Committee related to the most recent year's performance (the "Restricted Stock Program"). Restricted Stock Program grants vest annually over a four-year period (25% each year) beginning on January 1 of the year following the year in which the restricted stock award is granted. The cost of restricted stock grants, which is based upon the stock's fair market value on the grant date, is charged to earnings ratably over the vesting period. Through December 31, 2006 a total of 4,238,812 shares of restricted stock, net of forfeitures, have been awarded under the plan. Information regarding restricted stock awards are summarized in the following table for each of the years presented:

Exchange Rights

Limited partners in the Operating Partnership have the right to exchange all or any portion of their Units for shares of common stock on a one-for-one basis or cash, as selected by the Board. The amount of cash to be paid if the exchange right is exercised and the cash option is selected will be based on the trading price of Simon Property's common stock at that time. At December 31, 2006, we had reserved 79,592,963 shares of common stock for possible issuance upon the exchange of Units, options, Class B and C common stock and certain convertible preferred stock.

On November 15, 2004, the Attorneys General of Massachusetts, New Hampshire and Connecticut filed complaints in their respective state Superior Courts against us and our affiliate, SPGGC, Inc., alleging that the sale of co-branded, bank-issued gift cards sold in certain of its Portfolio Properties violated gift certificate statutes and consumer protection laws in those states. Each of these suits seeks injunctive relief, unspecified civil penalties and disgorgement of any fees determined to be improperly charged to consumers. We filed our own actions for declaratory judgment actions in Federal district courts in each of the three states.

With respect to the New Hampshire litigation, on August 1, 2006, the Federal district court in New Hampshire granted our motion for summary judgment and held that the gift card program that has been in existence since September 1, 2005 is a banking product and state law regulation is preempted by Federal banking laws. However, the Attorney General's appeal of this judgment in our favor in Federal district court in New Hampshire is pending. In February 2007, we entered into a voluntary, no-fault settlement agreement regarding the elements of the New Hampshire action which related to the program that existed before September 1, 2005. This settlement did not have a significant impact on the results of our operations.

In addition, we are a defendant in three other proceedings relating to the gift card program. Each of the three proceedings has been brought as a purported class action and alleges violation of state consumer protection laws, state abandoned property and contract laws or state statutes regarding gift certificates or gift cards and seeks a variety of remedies including unspecified damages and injunctive relief.

We believe that we have viable defenses under both state and federal laws to the above pending gift card actions. Although it is not possible to provide any assurance of the ultimate outcome of any of these pending actions, management does not believe that an adverse outcome would have a material adverse effect on our financial position, results of operations or cash flow.

As previously disclosed, we were a defendant in a suit brought against us by a partner in a partnership in which we previously held ownership in, Mall of America Associates (MOAA). Effective November 2, 2006, all parties agreed to settle the lawsuit and all claims with no settlement payment due by either party. Prior to that date we were a beneficial interest holder in the operations of MOAA which entitled us the right to receive cash flow distributions and capital transaction proceeds, or approximately a 25% interest in the underlying mall operations. Concurrently with the settlement of the litigation, the Simon family partner in MOAA sold its interest in MOAA and we received $102.2 million of capital transaction proceeds related to this transaction, terminating our beneficial interests, and resulting in a gain of $86.5 million.

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

120

financial position or our results of operations. We record a liability when a loss is considered probable and the amount can be reasonably estimated.

Lease Commitments

As of December 31, 2006, a total of 32 of the consolidated Properties are subject to ground leases. The termination dates of these ground leases range from 2007 to 2090. These ground leases generally require us to make payments of a fixed annual rent, or a fixed annual rent plus a participating percentage over a base rate based upon the revenues or total sales of the property. Some of these leases also include escalation clauses and renewal options. We incurred ground lease expense included in other expense and discontinued operations as follows:

|  | For the year ended December 31,
--- | --- | ---
|  | 2006 |  | 2005 |  | 2004
Ground lease expense |  | $ | 29,301 |  | $ | 25,584 |  | $ | 20,689

Future minimum lease payments due under such ground leases for years ending December 31, excluding applicable extension options, are as follows:

2007 |  | $ | 16,790
2008 |  |  | 17,036
2009 |  |  | 16,963
2010 |  |  | 16,746
2011 |  |  | 16,721
Thereafter |  |  | 705,710
|  | $ | 789,966

Insurance

We maintain commercial general liability, fire, flood, extended coverage and rental loss insurance on our Properties. Rosewood Indemnity, Ltd, a wholly-owned subsidiary of our management company, has agreed to indemnify our general liability carrier for a specific layer of losses. The carrier has, in turn, agreed to provide evidence of coverage for this layer of losses under the terms and conditions of the carrier's policy. A similar policy written through Rosewood Indemnity, Ltd. also provides initial coverage for property insurance and certain windstorm risks at the Properties located in Florida.

The events of September 11, 2001 affected our insurance programs. Although insurance rates remain high, since the President signed into law the Terrorism Risk Insurance Act (TRIA) in November of 2002, the price of terrorism insurance has steadily decreased, while the available capacity has been substantially increased. We have purchased terrorism insurance covering all Properties. The program provides limits up to $1 billion per occurrence for Certified (Foreign) acts of terrorism and $500 million per occurrence for Non-Certified (Domestic) acts of terrorism. The coverage is written on an "all risk" policy form that eliminates the policy aggregates associated with our previous terrorism policies. In December of 2005, the President signed into law the Terrorism Risk Insurance Extension Act (TRIEA) of 2005, thereby extending the federal terrorism insurance backstop through 2007. TRIEA narrows terms and conditions afforded by TRIA for 2006 and 2007 by: 1) excluding lines of coverage for commercial automobile, surety, burglary and theft, farm owners' multi-peril and professional liability; 2) raising the certifiable event trigger mechanism from $5 million to $50 million in 2006 and $100 million in 2007; and, 3) increasing the deductibles and co-pays assigned to insurance companies.

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 December 31, 2006, we have loan guarantees and other guarantee obligations of $43.6 million and $19.0 million, respectively, to support our total $3.5 billion share of joint venture mortgage and other indebtedness in the event 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.

Concentration of Credit Risk

We are subject to risks incidental to the ownership and operation of commercial real estate. These risks include, among others, the risks normally associated with changes in the general economic climate, trends in the retail industry, creditworthiness of tenants, competition for tenants and customers, changes in tax laws, interest rate and foreign currency levels, the availability of financing, and potential liability under environmental and other laws. Our regional malls, Premium Outlet centers and community/lifestyle centers rely heavily upon anchor tenants like most retail properties. Four retailers occupied 474 of the approximately 1,000 anchor stores in the Properties as of December 31, 2006. An affiliate of one of these retailers is a limited partner in the Operating Partnership.

Limited Life Partnerships

FASB Statement No. 150, "Accounting for Certain Financial Instruments with Characteristics of both Liabilities and Equity" ("SFAS 150") establishes standards for how an issuer classifies and measures certain financial instruments with characteristics of both liabilities and equity. It requires that an issuer classify a financial instrument that is within its scope as a liability. The effective date of a portion of the Statement has been indefinitely postponed by the FASB. We have certain transactions, arrangements, or financial instruments that have been identified that appear to meet the criteria for liability recognition in accordance with paragraphs 9 and 10 under SFAS 150 due to the finite life of certain joint venture arrangements. However, SFAS 150 requires disclosure of the estimated settlement value of these non-controlling interests. As of December 31, 2006 and 2005, the estimated settlement value of these non-controlling interests was approximately $175 million and $145 million, respectively.

12. Related Party Transactions

Our management company provides management, insurance, and other services to Melvin Simon & Associates, Inc. ("MSA"), a related party, and other non-owned properties. Amounts for services provided by our management company and its affiliates to our unconsolidated joint ventures and other related parties were as follows:

|  | For the year ended December 31,
--- | --- | ---
|  | 2006 |  | 2005 |  | 2004
Amounts charged to unconsolidated joint ventures |  | $ | 62,879 |  | $ | 58,450 |  | $ | 59,500
Amounts charged to properties owned by related parties |  |  | 9,494 |  |  | 9,465 |  |  | 9,694

13. Recently Issued Accounting Pronouncements

In December 2004, the Financial Accounting Standards Board ("FASB") issued SFAS No. 153, "Exchanges of Nonmonetary Assets — an amendment of Accounting Principles Board ("APB") Opinion No. 29." SFAS No. 153 requires exchanges of productive assets to be accounted for at fair value, rather than at carryover basis, unless: (a) neither the asset received nor the asset surrendered has a fair value that is determinable within reasonable limits; or (b) the transactions lack commercial substance. SFAS No. 153 is effective for nonmonetary asset exchanges

122

occurring in fiscal periods beginning after June 15, 2005. The adoption of this Statement did not have a material impact on our financial position or results of operations.

In December 2004, the FASB issued SFAS No. 123(R), "Share-Based Payment," which revises SFAS No. 123, "Accounting for Stock-Based Compensation." SFAS No. 123(R) supersedes APB Opinion No. 25, "Accounting for Stock Issued to Employees," and amends SFAS No. 95, "Statement of Cash Flows." This Statement requires that a public entity measure the cost of equity-based service awards based on the grant date fair value of the award. All share-based payments to employees, including grants of employee stock options, are required to be recognized in the income statement based on their fair value. SFAS No. 123(R) is effective as of the beginning of the first annual reporting period after June 15, 2005. Other than the reclassification of the unamortized portion of our restricted stock awards to capital in excess of par in the consolidated balance sheets, the adoption of this Statement did not have a material impact on our financial position or results of operations. We began expensing the vested portion of stock option awards to the recipients in the consolidated statements of operations in 2002.

In May 2005, the FASB issued SFAS No. 154, "Accounting Changes and Error Corrections." SFAS No. 154 is a replacement of APB Opinion No. 20, "Accounting Changes" and SFAS No. 3, "Reporting Accounting Changes in Interim Financial Statements." This Statement requires voluntary changes in accounting to be accounted for retrospectively and all prior periods to be restated as if the newly adopted policy had always been used, unless it is impracticable. APB Opinion No. 20 previously required most voluntary changes in accounting to be recognized by including the cumulative effect of the change in accounting in net income in the period of change. This Statement also requires a change in method of depreciation, amortization or depletion for a long-lived asset be accounted for as a change in estimate that is affected by a change in accounting principle. SFAS No. 154 is effective for fiscal years beginning after December 15, 2005. The adoption of this Statement did not have a material impact on our financial position or results of operations.

In June 2005, the FASB ratified its consensus in EITF Issue 04-05, "Determining Whether a General Partner, or the General Partners as a Group, Controls a Limited Partnership or Similar Entity When the Limited Partners Have Certain Rights" (Issue 04-05). The effective date for Issue 04-05 is June 29, 2005 for all new or modified partnerships and January 1, 2006 for all other partnerships for the applicable provisions. The adoption of the provisions of EITF 04-05 did not have a material impact on our financial position or results of operations.

In June 2005, the FASB ratified its consensus in EITF 05-06, "Determining the Amortization Period of Leasehold Improvements" (Issue 05-06). The effective date for Issue 05-06 is June 29, 2005. The adoption of the provisions of EITF 05-06 did not have a material impact on our financial position or results of operations.

During 2005, the FASB issued Interpretation No. 47, "Accounting for Conditional Asset Retirement Obligations — an interpretation of FASB Statement No. 143, Asset Retirement Obligations" ("FIN 47"). FIN 47 provides clarification of the term "conditional asset retirement obligation" as used in SFAS 143, defined as a legal obligation to perform an asset retirement activity in which the timing or method of settlement are conditional on a future event that may or may not be within our control. Under this standard, we must record a liability for a conditional asset retirement obligation if the fair value of the obligation can be reasonably estimated. FIN 47 became effective for our year ended December 31, 2005. The adoption of FIN 47 did not have a material adverse effect on our consolidated financial statements. Certain of our real estate assets contain asbestos. The asbestos is appropriately contained, in accordance with current environmental regulations, and we have no current plans to remove the asbestos. If these properties were demolished, certain environmental regulations are in place which specify the manner in which the asbestos must be handled and disposed. Because the obligation to remove the asbestos has an indeterminable settlement date, we are not able to reasonably estimate the fair value of this asset retirement obligation.

In June 2006, the FASB issued 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

123

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. FIN 48 becomes effective on January 1, 2007. We do not expect FIN 48 will have a material impact on our financial position or results of operations.

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.

14. Quarterly Financial Data (Unaudited)

Quarterly 2006 and 2005 data is summarized in the table below and, as disclosed in Note 3, the amounts have been reclassified from previously disclosed amounts due to presentation of the classification of the Limited Partners' interest in the Operating Partnership and the preferred distributions of the Operating Partnership.

15. Subsequent Event—Acquisition of the Mills Corporation

On February 16, 2007, SPG-FCM Ventures, LLC ("SPG-FCM") a newly formed joint venture owned 50% by an entity owned by Simon Property and 50% by funds managed by Farallon Capital Management, L.L.C. ("Farallon") entered into a definitive merger agreement with The Mills Corporation ("Mills") pursuant to which SPG-FCM will acquire Mills for $25.25 per common share in cash. The total value of the transaction is approximately $1.64 billion for all of the outstanding common stock of Mills and common units of The Mills Limited Partnership ("Mills LP") not owned by Mills, and approximately $7.3 billion, including assumed debt and preferred stock.

The acquisition will be completed through a cash tender offer at $25.25 per share for all outstanding shares of Mills common stock, which is expected to conclude in late March or early April 2007. If successful, the tender offer will be followed by a merger in which all shares not acquired in the offer will be converted into the right to receive the offer price. Completion of the tender offer is subject to the receipt of valid tenders of sufficient shares to result in ownership of a majority of Mills' fully diluted common shares and the satisfaction of other customary conditions. Mills LP common unitholders 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 upon a fixed exchange ratio of 0.211 Operating Partnership units for each unit of Mills LP.

In connection with the proposed transaction, we made a loan to Mills on February 16, 2007 to permit it to repay a loan facility provided by a previous bidder for Mills. The $1.188 billion loan to Mills carries a rate of LIBOR plus 270 basis points. The loan facility also permits Mills to borrow an additional $365 million on a revolving basis for working capital requirements and general corporate purposes. Simon Property or an affiliate of Mills will serve as the manager for all or a portion of the 38 properties that SPG-FCM will acquire an interest in following the completion of the tender offer.

We will be required to provide at least 50% of the funds necessary to complete the tender offer. We have and intend to obtain all funds necessary to fulfill our equity requirement for SPG-FCM, as well as any funds that we have or will provide in the form of loans to Mills, from available cash and our Credit Facility.
