TABLE OF CONTENTS

Part I

Item 1. Business

            Simon Property Group, Inc., or Simon Property, is a Delaware corporation that operates as a self-administered and self-managed real estate investment trust, or REIT, under the Internal Revenue Code. Simon Property Group, L.P., or the Operating Partnership, is our majority-owned partnership subsidiary that owns all of our real estate properties. In this report, the terms "we", "us" and "our" refer to Simon Property Group, Inc. and its subsidiaries.

            We own, develop, and manage retail real estate properties, which consist primarily of regional malls, Premium Outlet® centers, The Mills®, and community/lifestyle centers. As of December 31, 2007, we owned or held an interest in 320 income-producing properties in the United States, which consisted of 168 regional malls, 38 Premium Outlet centers, 67 community/lifestyle centers, 37 properties acquired in the Mills acquisition, and 10 other shopping centers or outlet centers in 41 states and Puerto Rico. Of the 37 Mills properties acquired, 17 of these are The Mills, 16 are regional malls, and four are community centers. We also own interests in four parcels of land held for future development. In the United States, we have four new properties currently under development aggregating approximately 2.75 million square feet which will open during 2008. Internationally, we have ownership interests in 51 European shopping centers (in France, Italy and Poland), six Premium Outlet centers in Japan, one Premium Outlet center in Mexico, and one Premium Outlet center in South Korea. Also, through a joint venture arrangement, we have a 32.5% interest in five shopping centers under development in China.

            For a description of our operational strategies and developments in our business during 2007, see the "Management's Discussion and Analysis of Financial Condition and Results of Operations" section of the 2007 Annual Report to Shareholders filed as Exhibit 13.1 to this Form 10-K.

Other Policies

            The following is a discussion of our investment policies, financing policies, conflict of interest policies and policies with respect to certain other activities. One or more of these policies may be amended or rescinded from time to time without a stockholder vote.

Investment Policies

            While we emphasize equity real estate investments, we may, at our discretion, invest in mortgages and other real estate interests consistent with our qualification as a REIT. We do not currently intend to invest to a significant extent in mortgages or deeds of trust; however, we hold an interest in one property through a mortgage note which results in us receiving 100% of the economics of the property. We may invest in participating or convertible mortgages if we conclude that we may benefit from the cash flow or any appreciation in the value of the property.

            We may invest in securities of other entities engaged in real estate activities or securities of other issuers. However, any of these investments would be subject to the percentage ownership limitations and gross income tests necessary for REIT qualification. These REIT limitations mean that we cannot make an investment that would cause our real estate assets to be less than 75% of our total assets. In addition, at least 75% of our gross income must be derived directly or indirectly from investments relating to real property or mortgages on real property, including "rents from real property," dividends from other REIT's and, in certain circumstances, interest from certain types of temporary investments. At least 95% of our income must be derived from such real property investments, and from dividends, interest and gains from the sale or dispositions of stock or securities or from other combinations of the foregoing.

            Subject to REIT limitations, we may invest in the securities of other issuers in connection with acquisitions of indirect interests in real estate. Such an investment would normally be in the form of general or limited partnership or membership interests in special purpose partnerships and limited liability companies that own one or more properties. We may, in the future, acquire all or substantially all of the securities or assets of other REITs, management companies or similar entities where such investments would be consistent with our investment policies.

Financing Policies

            We must comply with the covenants contained in our financing agreements that limit our ratio of debt to total asset or market value, as defined. For example, the Operating Partnership's lines of credit and the indentures for the

3

Operating Partnership's debt securities contain covenants that restrict the total amount of debt of the Operating Partnership to 65%, or 60% in relation to certain debt, of total assets, as defined under the related arrangement, and secured debt to 50% of total assets. In addition, these agreements contain other covenants requiring compliance with financial ratios. Furthermore, the amount of debt that we may incur is limited as a practical matter by our desire to maintain acceptable ratings for our equity securities and the debt securities of the Operating Partnership.

            If our Board of Directors determines to seek additional capital, we may raise such capital through additional equity offerings, debt financing, creating joint ventures with existing ownership interests in properties, retention of cash flows or a combination of these methods. Our ability to retain cash flows is limited by the requirement for REITs to distribute at least 90% of their taxable income. We must also take into account taxes that would be imposed on undistributed taxable income. If the Board of Directors determines to raise additional equity capital, it may, without stockholder approval, issue additional shares of common stock or other capital stock. The Board of Directors may issue a number of shares up to the amount of our authorized capital in any manner and on such terms and for such consideration as it deems appropriate. This may include issuing stock in exchange for property. Such securities may be senior to the outstanding classes of common stock. Such securities also may include additional classes of preferred stock, which may be convertible into common stock. Existing stockholders have no preemptive right to purchase shares in any subsequent offering of our securities. Any such offering could dilute a stockholder's investment in us.

            We expect most additional borrowings would be made through the Operating Partnership or its subsidiaries. We might, however, incur borrowings that would be reloaned to the Operating Partnership. Borrowings may be in the form of bank borrowings, publicly and privately placed debt instruments, or purchase money obligations to the sellers of properties. Any such indebtedness may be secured or unsecured. Any such indebtedness may also have full or limited recourse to the borrower or cross-collateralized with other debt, or may be fully or partially guaranteed by the Operating Partnership. Although we may borrow to fund the payment of dividends, we currently have no expectation that we will regularly be required to do so.

            We have a $3.5 billion revolving unsecured credit facility. We issue debt securities through the Operating Partnership, but we may issue our debt securities which may be convertible into capital stock or be accompanied by warrants to purchase capital stock. We also may sell or securitize our lease receivables. The proceeds from any borrowings or financings may be used for one or more of the following:

•

financing acquisitions;

•

developing or redeveloping properties;

•

refinancing existing indebtedness;

•

working capital or capital improvements; or

•

meeting the income distribution requirements applicable to REITs, if we have income without the receipt of cash sufficient to enable us to meet such distribution requirements.

            We may also finance acquisitions through the following:

•

issuance of shares of common stock or preferred stock;

•

issuance of additional units of limited partnership interest in the Operating Partnership;

•

issuance of preferred units of the Operating Partnership;

•

issuance of other securities; or

•

sale or exchange of ownership interests in properties.

            The ability of the Operating Partnership to issue units of limited partnership interest to transferors of properties or other partnership interests may defer gain recognition for tax purposes by the transferor. It may also be advantageous for us since there are ownership limits that restrict the number of shares of our capital stock that investors may own.

            We do not have a policy limiting the number or amount of mortgages that may be placed on any particular property. Mortgage financing instruments, however, usually limit additional indebtedness on such properties. We also have covenants on our unsecured debt that limit our total secured debt.

            Typically, we invest in or form special purpose entities to assist us in obtaining permanent financing on attractive terms. Permanent financing may be structured as a mortgage loan on a single property, or on a group of properties, and generally requires us to provide a mortgage interest on the property in favor of an institutional third party, as a joint venture with a third party, or as a securitized financing. For securitized financings, we create special purpose entities to own the properties. These special purpose entities are structured so that they would not be

4

consolidated with us in the event we would ever become subject to a bankruptcy proceeding. We decide upon the structure of the financing based upon the best terms then available to us and whether the proposed financing is consistent with our other business objectives. For accounting purposes, we include the outstanding securitized debt of special purpose entities owning consolidated properties as part of our consolidated indebtedness.

Conflict of Interest Policies

            We maintain policies and have entered into agreements designed to reduce or eliminate potential conflicts of interest. We have adopted governance principles governing our affairs and the Board of Directors, as well as written charters for each of the standing Committees of the Board of Directors. In addition, we have a Code of Business Conduct and Ethics, which applies to all of our officers, directors, and employees. At least a majority of the members of our Board of Directors must qualify as independent under the listing standards for New York Stock Exchange companies and cannot be affiliated with the Simon or DeBartolo families who are significant stockholders. Any transaction between us and the Simons or the DeBartolos, including property acquisitions, service and property management agreements and retail space leases, must be approved by a majority of our non-affiliated directors.

            The sale by the Operating Partnership of any property that it owns may have an adverse tax impact on the Simons or the DeBartolos and the other limited partners of the Operating Partnership. In order to avoid any conflict of interest between Simon Property and the limited partners of the Operating Partnership, our charter requires that at least six of our independent directors must authorize and require the Operating Partnership to sell any property it owns. Any such sale is subject to applicable agreements with third parties. Noncompetition agreements executed by each of the Simons contain covenants limiting the ability of the Simons to participate in certain shopping center activities in North America.

Policies With Respect To Certain Other Activities

            We intend to make investments which are consistent with our qualification as a REIT, unless the Board of Directors determines that it is no longer in our best interests to so qualify as a REIT. The Board of Directors may make such a determination because of changing circumstances or changes in the REIT requirements. We have authority to offer shares of our capital stock or other securities in exchange for property. We also have authority to repurchase or otherwise reacquire our shares or any other securities. We may issue shares of our common stock, or cash at our option, to holders of units of limited partnership interest in the Operating Partnership in future periods upon exercise of such holders' rights under the Operating Partnership agreement. Our policy prohibits us from making any loans to our directors or executive officers for any purpose. We may make loans to the joint ventures in which we participate.

Competition

            Our principal competitors are nine other major United States or internationally publicly-held companies that own or operate regional malls, outlet centers, and other shopping centers in the United States and abroad. We also compete with many commercial developers, real estate companies and other owners of retail real estate that operate in our trade areas. Some of our properties and investments are of the same type and are within the same market area as competitor properties. The existence of competitive properties could have a material adverse effect on our ability to lease space and on the level of rents we can obtain. This results in competition for both the acquisition of prime sites (including land for development and operating properties) and for tenants to occupy the space that we and our competitors develop and manage. In addition, our properties compete against other forms of retailing, such as catalog and e-commerce websites, that offer retail products and services.

            We believe that we have a competitive advantage in the retail real estate business as a result of:

•

the size, quality and diversity of our properties;

•

our management and operational expertise;

•

our extensive experience and relationships with retailers and lenders;

•

our mall marketing initiatives and consumer focused strategic corporate alliances; and

•

our ability to use our size to reduce the total occupancy cost of our tenants.

            Our size reduces our dependence upon individual retail tenants. Approximately 5,100 different retailers occupy more than 28,600 stores in our properties and no retail tenant represents more than 2.1% of our properties' total minimum rents.

Item 1A. Risk Factors

            The following factors, among others, could cause our actual results to differ materially from those contained in forward-looking statements made in this Annual Report on Form 10-K and presented elsewhere by our management from time to time. These factors, among others, may have a material adverse effect on our business, financial condition, operating results and cash flows, and you should carefully consider them. It is not possible to predict or identify all such factors. You should not consider this list to be a complete statement of all potential risks or uncertainties and we may update them in our future periodic reports.

Risks Relating to Debt and the Financial Markets

We have a substantial debt burden that could affect our future operations.

            As of December 31, 2007, our consolidated mortgages and other indebtedness, excluding the related premium and discount, totaled $17.2 billion, of which approximately $751 million matures during 2008, including recurring principal amortization on mortgages maturing during 2007. We are subject to the risks normally associated with debt financing, including the risk that our cash flow from operations will be insufficient to meet required debt service. Our debt service costs generally will not be reduced if developments at the property, such as the entry of new competitors or the loss of major tenants, cause a reduction in the income from the property. Should such events occur, our operations may be adversely affected. If a property is mortgaged to secure payment of indebtedness and income from the is insufficient to pay that indebtedness, the property could be foreclosed upon by the mortgagee resulting in a loss of income and a decline in our total asset value.

We depend on external financings for our growth and ongoing debt service requirements.

            We depend primarily on external financings, principally debt financings, to fund the growth of our business and to ensure that we can meet ongoing maturities of our outstanding debt. Our access to financing depends on our credit rating, the willingness of banks to lend to us and conditions in the capital markets which have experienced increasing volatility in recent months. We cannot assure you that we will be able to obtain the financing we need for future growth or to meet our debt service as obligations mature, or that the financing available to us will be on acceptable terms.

Adverse changes in our credit rating could affect our borrowing capacity and borrowing terms.

            Our outstanding senior unsecured notes and preferred stock are periodically rated by nationally recognized credit rating agencies. The credit ratings are based on our operating performance, liquidity and leverage ratios, overall financial position, and other factors viewed by the credit rating agencies as relevant to our industry and the economic outlook in general. Our credit rating can affect the amount of capital we can access, as well as the terms of any financing we obtain. Since we depend primarily on debt financing to fund our growth, adverse changes in our credit rating could have a negative effect on our future growth.

Our hedging interest rate protection arrangements may not effectively limit our interest rate risk.

            We manage our exposure to interest rate risk by a combination of interest rate protection agreements to effectively fix or cap a portion of our variable rate debt, or in the case of a fair value hedge, effectively convert fixed rate debt to variable rate debt. In addition, we refinance fixed rate debt at times when we believe rates and terms are appropriate. Our efforts to manage these exposures may not be successful.

            Our use of interest rate hedging arrangements to manage risk associated with interest rate volatility may expose us to additional risks, including a risk that a counterparty to a hedging arrangement may fail to honor its obligations. Developing an effective interest rate risk strategy is complex and no strategy can completely insulate us from risks associated with interest rate fluctuations. There can be no assurance that our hedging activities will have the desired beneficial impact on our results of operations or financial condition. Termination of these hedging agreements typically involves costs, such as transaction fees or breakage costs.

Factors Affecting Real Estate Investments and Operations

We face risks associated with the acquisition, development and expansion of properties.

            We regularly acquire and develop new properties and expand and redevelop existing properties, and these activities are subject to various risks. We may not be successful in pursuing acquisition, development or redevelopment/expansion opportunities. In addition, newly acquired, developed or redeveloped/expanded properties may not perform as well as expected. We are subject to other risks in connection with any acquisition, development and redevelopment/expansion activities, including the following:

•

construction costs of a project may be higher than projected, potentially making the project unfeasible or unprofitable;

•

we may not be able to obtain financing or to refinance construction loans on favorable terms, if at all;

•

we may be unable to obtain zoning, occupancy or other governmental approvals;

•

occupancy rates and rents may not meet our projections and the project may not be profitable; and

•

we may need the consent of third parties such as anchor tenants, mortgage lenders and joint venture partners, and those consents may be withheld.

            If a development or redevelopment/expansion project is unsuccessful, either because it is not meeting our expectations when operational or was not completed according to the project planning, we could lose our investment in the project. Further, if we guarantee the property's financing, our loss could exceed our investment in the project.

Real estate investments are relatively illiquid.

            Our properties represent a substantial portion of our total consolidated assets. These investments are relatively illiquid. As a result, our ability to sell one or more of our properties or investments in real estate in response to any changes in economic or other conditions is limited. If we want to sell a property, we cannot assure you that we will be able to dispose of it in the desired time period or that the sales price of a property will exceed the cost of our investment.

Environmental Risks

As owners of real estate, we can face liabilities for environmental contamination.

            Federal, state and local laws and regulations relating to the protection of the environment may require us, as a current or previous owner or operator of real property, to investigate and clean up hazardous or toxic substances or petroleum product releases at a property or at impacted neighboring properties. These laws often impose liability regardless of whether the property owner or operator knew of, or was responsible for, the presence of hazardous or toxic substances. These laws and regulations may require the abatement or removal of asbestos containing materials in the event of damage, demolition or renovation, reconstruction or expansion of a property and also govern emissions of and exposure to asbestos fibers in the air. Those laws and regulations also govern the installation, maintenance and removal of underground storage tanks used to store waste oils or other petroleum products. Many of our properties contain, or at one time contained, asbestos containing materials or underground storage tanks (primarily related to auto service center establishments or emergency electrical generation equipment). The costs of investigation, removal or remediation of hazardous or toxic substances may be substantial and could adversely affect our results of operations or financial condition but is not estimable. The presence of contamination, or the failure to remediate contamination, may also adversely affect our ability to sell, lease or redevelop a property or to borrow using a property as collateral.

Our efforts to identify environmental liabilities may not be successful.

            Although we believe that our portfolio is in substantial compliance with Federal, state and local environmental laws, ordinances and regulations regarding hazardous or toxic substances, this belief is based on limited testing. Nearly all of our properties have been subjected to Phase I or similar environmental audits. These environmental audits have not revealed, nor are we aware of, any environmental liability that we believe will have a material adverse effect on our results of operations or financial condition. However, we cannot assure you that:

•

existing environmental studies with respect to the portfolio reveal all potential environmental liabilities;

•

any previous owner, occupant or tenant of a property did not create any material environmental condition not known to us;

9

•

the current environmental condition of the portfolio will not be affected by tenants and occupants, by the condition of nearby properties, or by other unrelated third parties; or

•

future uses or conditions (including, without limitation, changes in applicable environmental laws and regulations or the interpretation thereof) will not result in environmental liabilities.

Retail Operations Risks

We are subject to risks that affect the general retail environment.

            Our concentration in the retail real estate market means that we are subject to the risks that affect the retail environment generally, including the levels of consumer spending, seasonality, the willingness of retailers to lease space in our shopping centers, tenant bankruptcies, changes in economic conditions, consumer confidence and terrorist activities. The possibility that the United States may currently be experiencing a recession could adversely affect consumer spending. Any one or more of these factors could adversely affect our results of operations or financial condition.

We may not be able to lease newly developed properties and renew leases and relet space at existing properties.

            We may not be able to lease new properties to an appropriate mix of tenants or for rents that are consistent with our projections. Also, when leases for our existing properties expire, the premises may not be relet or the terms of reletting, including the cost of allowances and concessions to tenants, may be less favorable than the current lease terms. To the extent that our leasing plans are not achieved, our cash generated before debt repayments and capital expenditures could be adversely affected.

Some of our properties depend on anchor stores or major tenants to attract shoppers and could be adversely affected by the loss of or a store closure by one or more of these tenants.

            Regional malls are typically anchored by department stores and other large nationally recognized tenants. The value of some of our properties could be adversely affected if these tenants fail to comply with their contractual obligations, seek concessions in order to continue operations, or cease their operations. Department store and larger store, also referred to as "big box", consolidations typically result in the closure of existing stores or duplicate or geographically overlapping store locations. We do not control the disposition of those department stores or larger stores that we do not own. We also may not control the vacant space that is not re-leased in those stores we do own. Other tenants may be entitled to modify the terms of their existing leases in the event of such closures. The modification could be unfavorable to us as the lessor and could decrease rents or expense recovery charges. Additionally, major tenant closures may result in decreased customer traffic which could lead to decreased sales at other stores. If the sales of stores operating in our properties were to decline significantly due to closing of anchors, economic conditions, or other reasons, tenants may be unable to pay their minimum rents or expense recovery charges. In the event of default by a tenant or anchor store, we may experience delays and costs in enforcing our rights as landlord to recover amounts due to us under the terms of our agreements with those parties.

We face potential adverse effects from tenant bankruptcies.

            Bankruptcy filings by retailers occur frequently in the course of our operations. We are continually re-leasing vacant spaces resulting from tenant terminations. The bankruptcy of a tenant, particularly an anchor tenant, may make it more difficult to lease the remainder of the affected properties. Future tenant bankruptcies could adversely affect our properties or impact our ability to successfully execute our re-leasing strategy.

Risks Relating to Joint Venture Properties

We have limited control with respect to some properties that are partially owned or managed by third parties, which may adversely affect our ability to sell or refinance them.

            As of December 31, 2007, we owned interests in 181 income-producing properties with other parties. Of those, 19 properties are included in our consolidated financial statements. We account for the other 162 properties under the equity method of accounting, which we refer to as joint venture properties. We serve as general partner or property manager for 93 of these 162 properties; however, certain major decisions, such as selling or refinancing these properties, require the consent of the other owners. Of the properties for which we do not serve as general partner or

10

property manager, 59 are in our international joint ventures. The other owners also have other participating rights that we consider substantive for purposes of determining control over the properties' assets. The remaining joint venture properties are managed by third parties. These limitations may adversely affect our ability to sell, refinance, or otherwise operate these properties.

The Operating Partnership guarantees debt or otherwise provides support for a number of joint venture properties.

            Joint venture debt is the liability of the joint venture and is typically secured by a mortgage on the joint venture property. As of December 31, 2007, the Operating Partnership has loan guarantees and other guarantee obligations to support $132.5 million and $60.6 million, respectively, of our total $6.6 billion share of joint venture mortgage and other indebtedness. A default by a joint venture under its debt obligations may expose us to liability under a guaranty or letter of credit.

Other Factors Affecting Our Business

Our Common Area Maintenance (CAM) contributions may not allow us to recover the majority of our operating expenses from tenants.

            CAM costs typically include allocable energy costs, repairs, maintenance and capital improvements to common areas, janitorial services, administrative, property and liability insurance costs, and security costs. We historically have used leases with variable CAM provisions that adjust to reflect inflationary increases. However, we are making a concerted effort to shift from variable to fixed CAM contributions for our cost recoveries which will fix our tenants' CAM contributions to us. As a result, our CAM contributions may not allow us to recover a substantial portion of these operating costs.

We face a wide range of competition that could affect our ability to operate profitably.

            Our properties compete with other retail properties for tenants on the basis of the rent charged and location. The principal competition may come from existing or future developments in the same market areas and from discount shopping centers, outlet malls, catalogues, discount shopping clubs and electronic commerce. The presence of competitive properties also affects our ability to lease space and the level of rents we can obtain. Renovations and expansions at competing malls could also negatively affect our properties.

            We also compete with other retail property developers to acquire prime development sites. In addition, we compete with other retail property companies for attractive tenants and qualified management.

Our international expansion may subject us to different or greater risk from those associated with our domestic operations.

            We hold interests in joint venture properties that are under operation in Europe, Japan, South Korea, and Mexico. We have also established arrangements to develop joint venture properties in China, and expect to pursue additional expansion opportunities outside the United States. International development and ownership activities carry risks that are different from those we face with our domestic properties and operations. These risks include:

•

adverse effects of changes in exchange rates for foreign currencies;

•

changes in foreign political and economic environments, regionally, nationally, and locally;

•

challenges of complying with a wide variety of foreign laws including corporate governance, operations, taxes, and litigation;

•

differing lending practices;

•

differences in cultures;

•

changes in applicable laws and regulations in the United States that affect foreign operations;

•

difficulties in managing international operations; and

•

obstacles to the repatriation of earnings and cash.

            Although our international activities currently are a relatively small portion of our business (international properties represented less than 6% of the GLA of all of our properties at December 31, 2007), to the extent that we expand our international activities, these risks could increase in significance which in turn could adversely affect our results of operations and financial condition.

11

Some of our potential losses may not be covered by insurance.

            We maintain commercial general liability "all risk" property coverage including fire, flood, extended coverage and rental loss insurance on our properties. Our captive insurance company subsidiaries indemnify our general liability carrier for a specific layer of losses. A similar policy written through our subsidiary also provides a portion of our initial coverage for property insurance and certain windstorm risks at the properties located in coastal windstorm locations. Even insured losses could result in a serious disruption to our business and delay our receipt of revenue.

            There are some types of losses, including lease and other contract claims that generally are not insured. If an uninsured loss or a loss in excess of insured limits occurs, we could lose all or a portion of the capital we have invested in a property, as well as the anticipated future revenue from the property. If this happens, we may still remain obligated for any mortgage debt or other financial obligations related to the property.

            We currently maintain insurance coverage against acts of terrorism on all of our properties on an "all risk" basis in the amount of 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 current federal laws which provide this coverage are expected to operate through 2014. Despite the existence of this insurance coverage, any threatened or actual terrorist attacks in high profile markets could adversely affect our property values, revenues, consumer traffic and tenant sales.

Inflation may adversely affect our financial condition and results of operations.

            Although inflation has not materially impacted our operations in the recent past, increased inflation could have a more pronounced negative impact on our mortgage and debt interest and general and administrative expenses, as these costs could increase at a rate higher than our rents. Also, inflation may adversely affect tenant leases with stated rent increases, which could be lower than the increase in inflation at any given time. Inflation could also have an adverse effect on consumer spending which could impact our tenants' sales and, in turn, our overage rents, where applicable.

Risks Relating to Federal Income Taxes

Our failure to qualify as a REIT would have adverse tax consequences to us and our stockholders.

            We cannot assure you that we will remain qualified as a REIT. Qualification as a REIT for federal income tax purposes is governed by highly technical and complex provisions for which there are only limited judicial or administrative interpretations. If we fail to comply with those provisions, we may be subject to monetary penalties or ultimately to possible disqualification as a REIT. If such events occurs, and if available relief provisions do not apply:

•

we will not be allowed a deduction for distributions to stockholders in computing our taxable income;

•

we will be subject to corporate level income tax, including any applicable alternative minimum tax, on our taxable income at regular corporate rates; and

•

unless entitled to relief under relevant statutory provisions, we will also be disqualified from treatment as a REIT for the four taxable years following the year during which qualification was lost.

            As a result, net income and funds available for distribution to our stockholders will be reduced for those years in which we fail to qualify as a REIT. Also, we would no longer be required to distribute money to our stockholders. Although we currently intend to operate so as to qualify as a REIT, future economic, market, legal, tax or other considerations might cause us to revoke our REIT election.

Item 2. Properties

United States Properties

            Our U.S. properties primarily consist of regional malls, Premium Outlet centers, The Mills ®, community/lifestyle centers, and other properties. These properties contain an aggregate of approximately 242 million square feet of gross leasable area, or GLA, of which we own approximately 150.8 million square feet. Total estimated retail sales at the properties in 2007 were approximately $60 billion.

            Regional malls typically contain at least one traditional department store anchor or a combination of anchors and big box retailers with a wide variety of smaller stores connecting the anchors. Additional stores are usually located along the perimeter of the parking area. Our 168 regional malls are generally enclosed centers and range in size from approximately 400,000 to 2.3 million square feet of GLA. Our regional malls contain in the aggregate more than 18,300 occupied stores, including approximately 675 anchors, which are mostly national retailers.

            Premium Outlet centers generally contain a wide variety of retailers located in open-air manufacturers' outlet centers. Our 38 Premium Outlet centers range in size from approximately 200,000 to 850,000 square feet of GLA. The Premium Outlet centers are generally located near metropolitan areas including New York City, Los Angeles, Chicago, Boston, Washington, D.C., and San Francisco; or within 20 miles of major tourist destinations including Palm Springs, Napa Valley, Orlando, Las Vegas, and Honolulu.

            The Mills portfolio consists of Mills centers, regional malls, and community centers. The 17 Mills centers generally range in size from 1.0 million to 2.3 million square feet of GLA. The Mills centers are located in major metropolitan areas and have a combination of traditional mall, outlet center, and big box retailers and entertainment uses. The 16 regional malls typically range in size from 700,000 to 1.3 million square feet of GLA and contain a wide variety of national retailers. The four community centers are adjacent to Mills centers, and contain a mix of big box and other local and national retail tenants.

            Community/lifestyle centers are generally unenclosed and smaller than our regional malls. Our 67 community/lifestyle centers generally range in size from approximately 100,000 to 900,000 square feet of GLA. Community/lifestyle centers are designed to serve a larger trade area and typically contain anchor stores and other tenants that are usually national retailers among the leaders in their markets. These tenants generally occupy a significant portion of the GLA of the center. We also own traditional community shopping centers that focus primarily on value-oriented and convenience goods and services. These centers are usually anchored by a supermarket, discount retailer, or drugstore and are designed to service a neighborhood area. Finally, we own open-air centers adjacent to our regional malls designed to take advantage of the drawing power of the mall.

            We also have interests in 10 other shopping centers or outlet centers. These properties range in size from approximately 85,000 to 300,000 square feet of GLA and in total represent less than 1% of our total operating income before depreciation.

            The following table provides representative data for our U.S. properties as of December 31, 2007:

            As of December 31, 2007, approximately 93.5% of the owned GLA in regional malls and the retail space of the other properties was leased, approximately 99.7% of owned GLA in the Premium Outlet centers was leased, approximately 94.1% of the owned GLA for the Mills and 89.5% of owned GLA for the Mills regional malls was leased, and approximately 94.1% of owned GLA in the community/lifestyle centers was leased.

13

            We own 100% of 198 of our properties, effectively control 19 properties in which we have a joint venture interest, and hold the remaining 103 properties through unconsolidated joint venture interests. We are the managing or co-managing general partner or member of 310 properties. Substantially all of our joint venture properties are subject to rights of first refusal, buy-sell provisions, or other sale rights for all partners which are customary in real estate partnership agreements and the industry. Our partners in our joint ventures may initiate these provisions at any time, which will result in either the use of available cash or borrowings to acquire their partnership interest or the disposal of our partnership interest.

            The following property table summarizes certain data on our regional malls, Premium Outlet centers, the properties acquired in the Mills acquisition, and community/lifestyle centers located in the United States, including Puerto Rico, as of December 31, 2007.
