Part I

Item 1.    Business

            Simon Property Group, L.P. is a Delaware limited partnership and the majority-owned subsidiary of Simon Property Group, Inc. In this report, the terms "Operating Partnership", "we", "us" and "our" refer to Simon Property Group, L.P. and its subsidiaries and the term "Simon Property" refers specifically to Simon Property Group, Inc.

            We own, develop, and manage retail real estate properties in five retail real estate platforms: regional malls, Premium Outlet Centers®, The Mills®, community/lifestyle centers, and international properties. As of December 31, 2008, we owned or held an interest in 324 income-producing properties in the United States, which consisted of 164 regional malls, 16 additional regional malls and four additional community centers acquired as a result of the 2007 acquisition of The Mills Corporation, or the Mills acquisition, 40 Premium Outlet Centers, 16 The Mills, 70 community/lifestyle centers, and 14 other shopping centers or outlet centers in 41 states and Puerto Rico. We also own interests in four parcels of land held for future development. In the United States, we have one new property currently under development aggregating approximately 0.4 million square feet which will open during 2009. Internationally, we have ownership interests in 52 European shopping centers (in France, Italy and Poland), seven Premium Outlet Centers in Japan, one Premium Outlet Center in Mexico, one Premium Outlet Center in Korea, and one shopping center in China. Also, through joint venture arrangements we have ownership interests in the following properties under development internationally: a 24% interest in two shopping centers in Italy, a 40% interest in a Premium Outlet Center in Japan, and a 32.5% interest in three additional shopping centers under construction in China.

            For a description of our operational strategies and developments in our business during 2008, see the "Management's Discussion and Analysis of Financial Condition and Results of Operations" which appears in Item 7 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 One or more of these policies may be amended or rescinded from time to time by Simon Property without a vote by our limited partners.

Investment Policies

            While we emphasize equity real estate investments, we may, at our discretion, invest in mortgages and other real estate interests consistent with Simon Property's qualification as a real estate investment trust, or REIT. We do not currently intend to invest to a significant extent in mortgages or deeds of trust; however, we hold a mortgage note which results in us receiving 100% of the economics of a 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 to maintain Simon Property's qualification as a REIT. These REIT limitations mean that Simon Property cannot make an investment that would cause its real estate assets to be less than 75% of its total assets. In addition, at least 75% of Simon Property's 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 Simon Property's 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 assets or market value, as defined. For example, our lines of credit and the indentures for our debt securities contain covenants that restrict the total amount of debt 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 Simon Property's equity securities and our debt securities.

            We may raise additional capital by issuing units of limited partnership interests, or units, or debt securities, creating joint ventures with existing ownership interests in properties, retention of cash flows or a combination of these methods. If Simon Property's Board of Directors determines to raise additional equity capital, at the Operating Partnership level, we may, without limited partner approval, issue additional units or other equity interests in us. We may issue Units in any manner and on such terms and for such consideration as we deem appropriate. This may include issuing Units in exchange for property. We may issue preferred units that could be senior to our Units and may be convertible into Units. Existing holders of Units have no preemptive right to purchase Units in any subsequent offerings. Any such offering could dilute a limited partner's investment in us.

            We expect most additional borrowings would be made 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 us. Although we may borrow to fund the payment of distributions, we currently have no expectation that we will regularly be required to do so.

            We have a $3.5 billion revolving unsecured credit facility, or the Credit Facility. We also issue debt securities, but we may issue our debt securities which may be convertible into Units, preferred units or be accompanied by warrants to purchase equity interests or be exchangeable for stock of Simon Property. 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

•

assisting Simon Property to meet the income distribution requirements applicable to REITs.

            We may also finance acquisitions through the following:

•

issuance of additional units or preferred units;

•

issuance of other securities; or

•

sale or exchange of ownership interests in properties.

            Our ability to issue Units 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 Units 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 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. Simon Property has adopted governance principles governing its affairs and the affairs of its subsidiaries and the Simon Property Board of Directors, as well as written charters for each of the standing Committees of the Board of Directors. In addition, the Board of Directors of Simon Property has a Code of Business Conduct and Ethics, which applies to all of its officers, directors, and employees. At least a majority of the members of the Simon Property Board of Directors must qualify as independent under the listing standards for New York Stock Exchange companies and cannot be affiliated with the Simon family who are significant stockholders. Any transaction between us and the Simons, including property acquisitions, service and property management agreements and retail space leases, must be approved by a majority of Simon Property's non-affiliated directors.

            The sale of certain of our properties may have an adverse tax impact on the Simons and the other limited partners. In order to avoid any conflict of interest between Simon Property and our limited partners, the Simon Property charter requires that at least six of the non-affiliated directors of the Board of Directors must authorize and require us to sell any property we own. 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 Simon Property's qualification as a REIT, unless the Board of Directors determines that it is no longer in Simon Property's 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 Units of equity interest or other securities in exchange for property. We also have authority to repurchase or otherwise reacquire our Units or any other securities. Our policy prohibits us from making any loans to the directors or executive officers of Simon Property for any purpose. We may make loans to the joint ventures in which we participate.

Competition

            Our principal competitors are nine 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 companies 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 4,300 different retailers occupy more than 28,600 stores in our properties and no retail tenant represents more than 2.0% of our properties' total minimum rents.

Certain Activities

            During the past three years, we have:

•

issued 4,353,882 units to Simon Property upon the exchange of units for common stock of Simon Property;

•

issued 5,426,696 units to other partners upon the conversion of 6,786,886 Series I preferred units;

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, 2008, our consolidated mortgages and other indebtedness, excluding the related premium and discount, totaled $18.0 billion, of which approximately $1.5 billion matures during 2009, including recurring principal amortization on mortgages maturing during 2009. 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 property 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.

The ongoing disruption in the credit markets may adversely affect our ability to access 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. The disruption in the capital markets that began in 2008 has continued into 2009, restricting access to capital markets for many companies. 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 the preferred stock of Simon Property are periodically rated by nationally recognized credit rating agencies. These 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. These credit ratings can also 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;

8

---

Table of Contents

•

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

Deteriorating economic conditions are adversely affecting 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. A recession is currently affecting the economy and consumer spending in the United States has recently declined. The unemployment rate is rising and consumer confidence has decreased significantly. In addition, we derive our cash flow from operations primarily from retail tenants, many of whom are currently under considerable economic stress. A prolonged recession is likely to adversely affect our tenants and as a result this could affect our results of operations and financial condition. A significant deterioration in our cash flow from operations could require us to curtail planned capital expenditures or seek alternative sources of financing.

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. 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 the increasing number of tenant bankruptcies.

            Although bankruptcy filings by retailers occur regularly in the course of our operations, the number of tenant bankruptcies has increased substantially in the past twelve months. We continually seek to re-lease 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, 2008, we owned interests in 183 income-producing properties with other parties. Of those, 18 properties are included in our consolidated financial statements. We account for the other 165 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 165 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 property manager, 62 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.

We guarantee debt or otherwise provide 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, 2008, we had loan guarantees and other guarantee obligations to support $71.9 million and $6.6 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. Recently, we have made a concerted effort to convert our leases to a fixed payment methodology which fixes our tenants' CAM contributions and should in turn reduce the volatility of and limitations on the recoveries we collect from our tenants for the reimbursement of our property operating expenses. However, with respect to both variable and fixed payment methodologies, the amount of CAM charges we bill to our tenants may not allow us to recover all 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 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 Italy, France, Poland, Japan, Korea, Mexico, and China and we have recently made an investment in a U.K. retail real estate company. We may 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;

obstacles to the repatriation of earnings and cash.

            Although our international activities currently are a relatively small portion of our business (international properties represented approximately 6.3% of the GLA of all of our properties at December 31, 2008), 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.

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

            We maintain commercial general liability, fire, flood, extended coverage and rental loss insurance on all of our properties in the United States through wholly-owned captive insurance entities and other self-insurance mechanisms. Rosewood Indemnity, Ltd. and Bridgewood Insurance Company, Ltd. are our wholly-owned captive insurance subsidiaries, and have agreed to indemnify our general liability carrier for a specific layer of losses for the properties that are covered under these arrangements. 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 these captive insurance entities also provides initial coverage for property insurance and certain windstorm risks at the properties located in coastal windstorm locations.

            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 in the United States 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.

Risks Relating to Federal Income Taxes

The failure of either of our two REIT subsidiaries to maintain its qualification as a REIT would have adverse tax consequences to us, our unitholders, and Simon Property.

            Two of our subsidiaries have elected to qualify 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 either of the REIT subsidiaries fails to comply with those provisions, and if available relief provisions do not apply:

•

The REIT subsidiary will not be allowed a deduction for distributions to us in computing its taxable income;

•

The REIT subsidiary will be subject to corporate level income tax, including any applicable alternative minimum tax, on its taxable income at regular corporate rates;

•

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

•

Simon Property would also fail to qualify as a REIT as a result of the subsidiary's failure and the same adverse consequences would apply to it and its stockholders.

            As a result, net income and funds available for distribution to our unitholders would be reduced for those years in which a REIT subsidiary fails to qualify as a REIT. Although we currently intend to operate the REIT subsidiaries so as to qualify each as a REIT, we cannot assure you we will succeed or that future economic, market, legal, tax or other considerations might cause us to revoke the REIT election of either of the REIT subsidiaries.

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 246 million square feet of gross leasable area, or GLA, of which we own approximately 152.8 million square feet. Total estimated retail sales at the properties in 2008 were approximately $62 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 164 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 19,300 occupied stores, including approximately 740 anchors, which are mostly national retailers. The 16 regional malls acquired in the Mills acquisition are identified in this section as the Mills Regional Malls. These malls typically range in size from 700,000 to 1.3 million square feet of GLA and contain a wide variety of national retailers.

            Premium Outlet Centers generally contain a wide variety of designer and manufacturer stores located in an open-air center. Our 40 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 major metropolitan areas and tourist destinations including New York City, Los Angeles, Boston, Palm Springs, Orlando, Las Vegas, and Honolulu.

            The Mills generally range in size from 1.0 million to 2.3 million square feet of GLA and are located in major metropolitan areas. They have a combination of traditional mall, outlet center, and big box retailers and entertainment uses.

            Community/lifestyle centers are generally unenclosed and smaller than our regional malls. Our 70 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 national retail tenants, which 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 14 other shopping centers or outlet centers. These properties range in size from approximately 85,000 to 1.0 million 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 on a gross basis as of December 31, 2008:

            As of December 31, 2008, approximately 92.4% of the owned GLA in regional malls and the retail space of the other properties was leased, approximately 98.9% of owned GLA in the Premium Outlet Centers was leased, approximately 94.5% of the owned GLA for The Mills and 87.4% of owned GLA for the Mills regional malls was leased, and approximately 90.7% of owned GLA in the community/lifestyle centers was leased.

            We own 100% of 203 of our properties, effectively control 18 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 314 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 for our regional malls, Premium Outlet Centers, the Mills portfolio, and community/lifestyle centers located in the United States, including Puerto Rico, as of December 31, 2008.

International Properties

            Our ownership interests in entities that operate properties outside the United States are primarily owned through joint venture arrangements. However, during 2008, we acquired shares of stock of Liberty International, PLC, or Liberty, as further described below.

European Investments

            The following summarizes our joint venture investments in Europe and the underlying countries in which these joint ventures own and operate real estate properties as of December 31, 2008:

            In addition, we jointly hold with a third party an interest in one parcel of land for development near Paris, France outside of these two joint ventures. Simon Ivanhoe and GCI are fully integrated European retail real estate developers, owners and managers.

            Our properties in Europe consist primarily of hypermarket-anchored shopping centers. Substantially all of our European properties are anchored by either the hypermarket retailer Auchan, primarily in Italy, who is also our partner in GCI, or are anchored by the hypermarket Carrefour in France and Poland. Certain of the properties in Italy are subject to leaseholds whereby GCI leases all or a portion of the premises from a third party who is entitled to receive substantially all the economic benefits of that portion of the properties. Auchan and Carrefour are the two largest hypermarket operators in Europe.

Other International Investments

            We also hold real estate interests in seven joint venture properties in Japan, one property in Mexico, one property in Korea, and one property in China. The seven Japanese Premium Outlet Centers operate in various cities throughout Japan and are held in a joint venture with Mitsubishi Estate Co., Ltd. and Sojitz Corporation (formerly known as Nissho Iwai Corporation). These centers comprise over 2.0 million square feet of GLA and were 99.9% leased as of December 31, 2008. They contain 854 stores with approximately 380 different tenants. The Premium Outlet Center in Mexico was 92% leased as of December 31, 2008, and the Premium Outlet Center in Korea was 100% leased as of December 31, 2008. The center in Changshu, China was 98% occupied as of December 31, 2008.

            The following summarizes these nine Premium Outlet Centers in international joint ventures:

            In 2008, we completed construction on Sendai Izumi Premium Outlets, a 164,000 square foot center located in Sendai, Japan. We have a 40% interest in this property consistent with the ownership structure of our other Japanese investments. Also, through joint venture arrangements, we have a 32.5% interest in four shopping centers in China, one of which is open and three that are under construction, aggregating 2.0 million square feet of GLA.

            Liberty operates regional shopping centers and is the owner of other prime retail assets throughout the U.K. Liberty is a U.K. FTSE 100 listed company, with shareholders' funds of £4.7 billion and property investments of

£8.6 billion, of which its U.K. regional shopping centers comprise 75%. Assets of the group under control or joint control amount to £11.0 billion. Liberty converted into a U.K. Real Estate Investment Trust (REIT) on January 1, 2007. Our interest in Liberty is less than 5% of their shares and is adjusted to their quoted market price, including a related foreign exchange component.

Item 3.    Legal Proceedings

             As previously disclosed, for several years we have been defending actions brought by the Attorneys General of Massachusetts, New Hampshire and Connecticut in their respective state courts and similar litigation brought by other parties alleging that the sale of co-branded, bank-issued gift cards by our affiliate, SPGGC, Inc., at certain of our properties, violated state gift certificate and consumer protection laws. We previously reported the dismissal of the New Hampshire litigation. During the fourth quarter of 2008, the complaint in the Massachusetts litigation was dismissed and we settled the Connecticut litigation. The only remaining legal proceedings involving gift card sales are two purported class actions brought by private parties in New York. With the resolution of the remaining Attorneys General's actions in 2008, we no longer believe that the ultimate outcome of these related actions would have a material adverse effect on our financial position, results of operations or cash flows and, accordingly, we do not expect to report further developments in these actions.

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

Part II

Item 5.    Market for the Registrant's Common Equity, Related Stockholder Matters, and Issuer Purchases of Equity Securities

Market Information

            There is no established trading market for our units or preferred units. The following table sets forth for the periods indicated, the distributions declared on our common units:

Holders

            The number of holders of record of units was 255 as of February 24, 2009.

Distributions

            We make distributions to our limited and general partners in order to maintain Simon Property's qualification as a REIT. Simon Property is required each year to distribute to its stockholders at least 90% of its taxable income after certain adjustments. Future distributions will be determined at the discretion of Simon Property's Board of Directors based on actual results of operations, cash available for distribution, and what may be required to maintain Simon Property's status as a REIT.

            On January 30, 2009, Simon Property's Board of Directors approved a quarterly common stock dividend of $0.90 per share, to be paid in a combination of cash and shares of its common stock. The distribution rate on our units is equal to the dividend rate on Simon Property's common stock. While our unitholders will have the right to elect to receive their distribution in either cash or units, we have announced that the aggregate cash component of the distribution will not exceed 10% of the total distribution, or $0.09 per unit. If the number of unitholders electing to receive cash would result in the payment of cash in excess of this 10% limitation, we will allocate the cash payment on a pro rata basis among those unitholders making the cash election. Simon Property has reserved the right to elect to pay the first quarter dividend, and as a result our distribution, all in cash. Simon Property's Board of Directors reviews and approves Simon Property's dividends and, as a result, our distributions, on a quarterly basis, and no determination has been made about whether the remaining 2009 dividends will be paid in a similar combination of cash and common stock. Paying all or a portion of its remaining 2009 dividends in a combination of cash and common stock allows Simon Property to satisfy its REIT taxable income distribution requirement under existing IRS revenue procedures, while enhancing financial flexibility and balance sheet strength.

Unregistered Sales of Equity Securities

            During the fourth quarter of 2008, Simon Property issued 339,621 shares of its common stock to limited partners in exchange for an equal number of units. The issuance of the shares of common stock was made pursuant to the terms of our Partnership Agreement and was exempt from registration under the Securities Act of 1933 as amended, in reliance upon Section 4(2).

Issuer Purchases of Equity Securities

            The Simon Property Board of Directors has authorized the repurchase of up to $1.0 billion of its common stock through July 2009. Simon Property may repurchase shares in the open market or in privately negotiated transactions. As of December 31, 2008, the program had remaining availability of approximately $950.7 million. There were no purchases under this program during the fourth quarter of 2008. If Simon Property acquires shares of its common stock, then we would repurchase an equal number of our units from Simon Property.

Overview

            Simon Property Group, L.P. is a Delaware limited partnership and the majority-owned subsidiary of Simon Property Group, Inc. In this discussion, the terms "Operating Partnership", "we", "us" and "our" refer to Simon Property Group, L.P. and its subsidiaries and the term "Simon Property" refers specifically to Simon Property Group, Inc.

            We own, develop, and manage retail real estate properties in five retail real estate platforms: regional malls, Premium Outlet Centers®, The Mills®, community/lifestyle centers, and international properties. As of December 31, 2008, we owned or held an interest in 324 income producing properties in the United States, which consisted of 164 regional malls, 70 community/lifestyle centers, 16 additional regional malls and four additional community centers acquired as a result of the 2007 acquisition of The Mills Corporation, or the Mills acquisition, 40 Premium Outlet Centers, 16 The Mills, and 14 other shopping centers or outlet centers in 41 states plus Puerto Rico. The Mills acquisition is described below in the "Results of Operations" section. We also own interests in four parcels of land held in the United States for future development. In the United States, we have one new property currently under development aggregating approximately 400,000 square feet which will open during 2009. Internationally, we have ownership interests in 52 European shopping centers (located in France, Italy, and Poland); seven Premium Outlet Centers located in Japan, one Premium Outlet Center located in Mexico, one Premium Outlet Center located in Korea, and one shopping center located in China. Also, through joint venture arrangements we have ownership interests in the following properties under development internationally: a 24% interest in two shopping centers in Italy, a 40% interest in a Premium Outlet Center in Japan, and a 32.5% interests in three additional shopping centers under construction in China.

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

•

Base minimum rents,



•

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 taxes, repair and maintenance, and advertising and promotional expenditures.

            Revenues of our management company, after intercompany eliminations, consist primarily of management fees that are typically based upon the revenues of the property being managed.

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

•

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



•

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



•

Adding mixed-use elements to properties,



•

Selectively acquiring high quality real estate assets or portfolios of assets, and



•

Selling non-core assets.

            We also grow by generating supplemental revenues from the following activities:

•

Establishing our malls as leading market resource providers for retailers and other businesses and consumer-focused corporate alliances, including: payment systems (including handling fees relating to the sales of bank-issued prepaid cards), national marketing alliances, static and digital media initiatives, business development, sponsorship, and events,



•

Offering property operating services to our tenants and others, including waste handling and facility services, and the sale of energy,

•

Selling or leasing land adjacent to our shopping center properties, commonly referred to as "outlots" or "outparcels," and

            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 ability to complement 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 growth, we employ a three-fold capital strategy:

•

Provide the capital necessary to fund growth,



•

Maintain sufficient flexibility to access capital in many forms, both public and private, and



•

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

Results Overview

            Diluted earnings per unit of limited partnership interest, or units, decreased $0.08 during 2008, or 4.1%, to $1.87 from $1.95 for 2007. The decrease is primarily due to the $20.3 million loss relating to the redemption of remarketable debt securities, and $21.2 million in impairment charges in 2008, as compared to net gains aggregating $9.0 million related to sales and disposition activity and impairment charges for the comparable period in 2007. Consolidated total revenues increased $132.4 million, or 3.6%, driven by the full year effect of our 2007 openings and expansion activities and the releasing of space at higher rental rates per square foot, or psf. Releasing spreads in the regional mall and Premium Outlet portfolios were strong at $8.02 psf (or 21.3%) and $12.48 psf (or 48.8%), respectively, due to continued demand for higher quality space in our portfolio. Total operating expenses increased $106.5 million, or 5.0%, due to additional depreciation provisions related to the full year of operations for 2007 openings and 2008 new openings, an increase in the provision for bad debts due to the estimated uncollectability of certain tenant receivables, and higher personnel and utility costs attributable to normal inflationary increases. Interest costs remained relatively flat despite an increase in total debt due to lowered variable borrowing costs as a result of a reduced one-month LIBOR rate, the benchmark rate for most of our floating rate debt.

            In the United States, business fundamentals were relatively stable, except for tenant sales psf which were mixed across the portfolio, and were dependent upon asset type, geographic location, and mix of specialty and luxury tenants. Average base rents for the regional mall and domestic Premium Outlet portfolios were relatively stable for 2008. The regional malls average base rent ended the year at $39.49 psf, or an increase of 6.5% over 2007. The domestic Premium Outlets average base rent ended the year at $27.65 psf, or an increase of 7.7%. The stability of the occupancy, rent psf, and releasing rental spread fundamentals contributed to our ability to generate growth in our operating results despite the adverse effects the general economic pressures are creating for our tenants and the consumer.

            Internationally, in 2008, we and our joint venture partners opened three additional centers (one each in Italy, China, and Japan) and expanded two existing Premium Outlet Centers which added an aggregate 1 million square feet of retail space to the international portfolio. Also during 2008, we acquired shares of stock of Liberty International, PLC, or Liberty. Liberty operates regional shopping centers and is the owner of other prime retail assets throughout the U.K. Liberty is a U.K. FTSE 100 listed company, with shareholders' funds of £4.7 billion and property investments of £8.6 billion, of which its U.K. regional shopping centers comprise 75%. Assets of the group under control or joint control amount to £11.0 billion. Liberty converted into a U.K. Real Estate Investment Trust (REIT) on January 1, 2007. Our interest in Liberty is less than 5% of their shares and is adjusted to their quoted market price, including a related foreign exchange component.

            Our effective overall borrowing rate for the year ended December 31, 2008, decreased 55 basis points to 5.12% as compared to the year ended December 31, 2007. This was a result of a significant decrease in the base LIBOR rate applicable to a majority of our floating rate debt (0.44% at December 31, 2008, versus 4.60% at December 31, 2007)

and also the issuance of new unsecured and secured debt at favorable rates. Our financing activities for the year ended December 31, 2008, included:

•

decreasing borrowings on our $3.5 billion unsecured credit facility, or Credit Facility, to approximately $1.0 billion during the year ended December 31, 2008. The amount outstanding includes $446.3 million (U.S. dollar equivalent) in Euro and Yen-denominated borrowings.



•

borrowing $735.0 million on a term loan that matures March 5, 2012 and bears a rate of LIBOR plus 70 basis points. This loan is secured by the cash flow distributed from six properties and has additional availability of $115.0 million through the maturity date.



•

issuing two tranches of senior unsecured notes in May totaling $1.5 billion at a weighed average fixed interest rate of 5.74%. We used the proceeds of the offering to reduce borrowings on the Credit Facility and for general working capital purposes.



•

redeeming the $200.0 million in remarkable debt securities that bore interest at 7.00%, and, as discussed above, resulted in our recognizing a $20.3 million loss in the second quarter related to this extinguishment of debt.



•

redeeming a $150.0 million unsecured note that bore interest at a fixed rate of 5.38%.



•

borrowing $190.0 million on a loan secured by Philadelphia Premium Outlets, which matures on July 30, 2014 and bears interest at a variable rate of LIBOR plus 185 basis points. On January 2, 2009, we executed a swap agreement that fixes the interest rate of this loan at 4.19%. We used the proceeds of the borrowing for general working capital purposes.



•

borrowing $260.0 million on a term loan that matures September 23, 2013 and bears interest at a variable rate of LIBOR plus 195 basis points. On January 2, 2009, we executed a swap agreement that fixes the interest rate of this loan at 4.35%. This is a cross-collateralized loan that is secured by The Domain, Shops at Arbor Walk, and Palms Crossing. We used the proceeds of the borrowing for general working capital purposes.

United States Portfolio Data

            The portfolio data discussed in this overview includes the following key operating statistics: occupancy; average base rent per square foot; and comparable sales per square foot for our four domestic platforms. We include acquired properties in this data beginning in the year of acquisition and remove properties sold in the year disposed. We are separately reporting in this section the 16 regional malls we acquired in the 2007 acquisition of The Mills Corporation, or the Mills acquisition. We do not include any properties located outside of the United States in this section. The following table sets forth these key operating statistics for:

•

properties that are consolidated in our consolidated financial statements,

•

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

•

the foregoing two categories of properties on a total portfolio basis.

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 Leasable Area, or GLA, owned by us in the regional malls, and all tenants at The Mills, Premium Outlet Centers, and community/lifestyle centers. Our portfolio has maintained relatively stable occupancy and increased the aggregate average base rents despite the current economic climate.

Table of Contents

            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 Mills and 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.

International Property Data

            The following are selected key operating statistics for certain of our international properties.

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 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 exceed its sales threshold.

•

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 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.

To maintain Simon Property's qualification as a REIT under the Internal Revenue Code, Simon Property is required to distribute at least 90% of its taxable income in any given year and meet certain asset and income tests. Simon Property monitors its business and transactions that may potentially impact its REIT status. In

the unlikely event that Simon Property fails to maintain its REIT status, and available relief provisions do not apply, then it would be required to pay federal income taxes at regular corporate income tax rates during the period it did not qualify as a REIT. If Simon Property lost its REIT status, it could not elect to be taxed as a REIT for four years unless its 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. This could adversely impact our ability to sell our debt securities and Simon Property's ability to sell its securities in the capital markets. We make distributions to our unitholders including Simon Property so that Simon Property can meet the REIT qualification requirements.

•

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.

            For the purposes of the following comparisons between the years ended December 31, 2008 and 2007 and the years ended December 31, 2007 and 2006, the above transactions are referred to as the property transactions. In the following discussions of our results of operations, "comparable" refers to properties open and operating throughout both the current and prior year.

            In 2008 we had no consolidated property dispositions. During 2007, we disposed of five consolidated properties that had an aggregate book value of $91.6 million for aggregate sales proceeds of $56.4 million, resulting in a net loss on sale of $35.3 million. The loss on sale of these assets has been reported as discontinued operations in the consolidated statements of operations. The operating results of the properties that we sold or disposed during 2007 were not significant to our consolidated results of operations. The following is a list of consolidated property dispositions and the date of disposition for which we have reported the operations or results of sale with discontinued operations:

            We sold the following properties in 2006. Due to the limited significance of these properties' operations and result of disposition on our consolidated financial statements, we did not report these properties as discontinued operations.

Year Ended December 31, 2008 vs. Year Ended December 31, 2007

            Minimum rents increased $137.2 million in 2008, of which the property transactions accounted for $64.6 million of the increase. Comparable rents increased $72.6 million, or 3.6%. This was primarily due to an increase in minimum rents of $82.1 million and an $8.5 million increase in straight-line rents, offset by a $16.4 million decrease in comparable property activity, primarily attributable to lower amounts of fair market value of in-place lease amortization.

            Overage rents decreased $9.8 million or 8.9%, as a result of a reduction in tenant sales for the period as compared to the prior year.

            Tenant reimbursements increased $42.8 million, due to a $26.9 million increase attributable to the property transactions and a $15.9 million, or 1.6%, increase in the comparable properties due to our ongoing initiative to convert leases to a fixed reimbursement methodology for common area maintenance costs.

            Management fees and other revenues increased $18.7 million principally as a result of the full year of additional management fees derived from managing the properties acquired in the Mills acquisition, and additional leasing and development fees as a result of incremental joint venture property activity.

57

Table of Contents

            Total other income decreased $56.6 million, and was principally the result of the following:

•

a $26.7 million decrease in interest income primarily due to the repayment of loans made to SPG-FCM and Mills, and lower interest rates attributable to this loan facility, combined with decreased interest earnings on investments due to lower excess cash balances and interest rates earned in 2008 as compared to 2007,

•

an $18.7 million decrease in lease settlement income as a result of significant lease settlements received from two department stores in 2007, and

•

a $14.3 million decrease in loan financing fees related to Mills-related loan activity during 2007 which did not recur in 2008.

These decreases were offset by a $3.1 million increase in net other activity.

            Depreciation and amortization expense increased $63.8 million in 2008 primarily due to our acquisition, expansion and renovation activity and the accelerated depreciation of tenant improvements for tenant leases terminated during the period and for properties scheduled for redevelopment.

            Real estate taxes increased $21.3 million from the prior period, $9.0 million of which is related to the property transactions, and $12.3 million from our comparable properties due to the effect of increases resulting from reassessments, higher tax rates, and the effect of expansion and renovation activities.

            Repairs and maintenance decreased $12.3 million due to our cost savings efforts.

            Provision for credit losses increased $14.5 million primarily due to an increase in tenant bankruptcies and tenant delinquencies. This was reflected in total square footage lost to tenant bankruptcies of 1,104,000 during 2008 as compared to only 69,000 square feet in 2007. We anticipate a challenging environment for our tenants continuing into 2009.

            Home and regional office expense increased $8.3 million primarily due to increased personnel costs, primarily the result of the Mills acquisition, and the increased expense from certain incentive compensation plans.

            Other expenses increased $5.8 million due to increased consulting and professional fees, including legal fees and related costs.

            Interest expense increased $1.3 million despite an $823.9 million increase in consolidated borrowings to fund our development and redevelopment activities, and the full year impact of our borrowings to fund the Mills-related loans, due to a 55 basis point decline in our weighted average borrowing rates. This decrease in weighted average borrowing rates was driven primarily by a decline in the applicable LIBOR rate for a majority of our consolidated floating rate debt instruments, including the Credit Facility.

            We recognized a loss on extinguishment of debt of $20.3 million in the second quarter of 2008 related to the redemption of $200 million in remarketable debt securities. We extinguished the debt because the remarketing reset base rate was above the rate for 30-year U.S. Treasury securities at the date of redemption.

            Income tax expense of taxable REIT subsidiaries increased $14.9 million due primarily to a $19.5 million tax benefit recognized in 2007 related to the impairment charge resulting from of the write-off of our investment in a land joint venture in Phoenix, Arizona.

            Income from unconsolidated entities decreased $5.9 million, due primarily to the impact of the Mills acquisition (net of eliminations). On a net basis, our share of loss from SPG-FCM increased $4.7 million from the prior period due to a full year of SPG-FCM activity in 2008 as compared to only nine months of activity in 2007. The loss was driven by depreciation and amortization expense on asset basis step-ups in purchase accounting.

            In 2008, we recognized an impairment of $21.2 million primarily representing the write-down of a mall property to its estimated net realizable value and the write-off of predevelopment costs for various development opportunities that we no longer plan to pursue. In 2007, we recognized an impairment of $55.1 million related to a land joint venture in Phoenix, Arizona.

            The gain on sale of assets and interests in unconsolidated entities of $92.0 million in 2007 was primarily the result of Simon Ivanhoe selling its interest in certain assets located in Poland.

            In 2007, the loss on sale of discontinued operations of $35.3 million represents the net loss upon disposition of five non-core properties consisting of three regional malls and two community/lifestyle centers.

            Preferred unit distribution requirements decreased $17.9 million as a result of the conversion or exchange of preferred units to units and the redemption of the Series G preferred units in the fourth quarter of 2007.

Year Ended December 31, 2007 vs. Year Ended December 31, 2006

            Minimum rents increased $133.9 million in 2007, of which the property transactions accounted for $87.0 million of the increase. Total amortization of the fair market value of in-place leases served to decrease minimum rents by $8.8 million due to certain in-place lease adjustments becoming fully amortized. Comparable rents increased $46.8 million, or 2.3%. This was primarily due to the leasing of space at higher rents that resulted in an increase in minimum rents of $54.6 million offset by a $9.2 million decrease in comparable property straight-line rents and fair market value of in-place lease amortization. In addition, rents from carts, kiosks, and other temporary tenants increased comparable rents by $1.4 million.

            Overage rents increased $14.2 million or 14.9%, reflecting increases in tenant sales.

            Tenant reimbursements increased $76.6 million, of which the property transactions accounted for $40.2 million. The remainder of the increase of $36.4 million, or 3.8%, was in comparable properties and was due to inflationary increases in property operating costs and our ongoing initiative of converting our leases to a fixed reimbursement methodology for common area maintenance costs.

            Management fees and other income increased $31.5 million principally as a result of additional management fees derived from the additional properties being managed from the Mills acquisition and additional leasing and development fees as a result of incremental property activity.

            Total other income increased $62.5 million, and was principally the result of the following:

•

a $46.4 million increase in interest income, of which $39.1 million is as a result of Mills-related loans, combined with increased interest rates on the investment of excess cash balances,

•

an $18.4 million increase in lease settlement income as a result of settlements received from two department stores in 2007,

•

a $17.4 million increase in loan financing fees, net of intercompany eliminations, related to Mills-related loan refinancing activity, offset by

•

a $19.7 million decrease in gains on land sale activity.

            Property operating expenses increased $13.3 million, or 3.0%, primarily as a result of the property transactions and inflationary increases.

            Depreciation and amortization expense increased $49.4 million and is primarily a result of the property transactions.

            Real estate taxes increased $13.1 million from the prior period, $10.4 million of which is related to the property transactions, and $2.7 million from our comparable properties due to the effect of increases resulting from reassessments, higher tax rates, and the effect of expansion and renovation activities.

            Repairs and maintenance increased $14.2 million due to increased snow removal costs in 2007 over that of 2006, normal inflationary increases, and the effect of the property transactions.

            Advertising and promotion increased $5.9 million primarily due to the effect of the property transactions.

            Home and Regional office expense increased $7.3 million primarily due to increased personnel costs, primarily the result of the Mills acquisition, and the effect of incentive compensation plans.

            General and administrative expenses increased $2.9 million due to increased executive salaries, principally as a result of additional share-based payment amortization from the vesting of restricted stock grants.

            Interest expense increased $124.0 million due principally to the following:

•

increased borrowings to fund our development and redevelopment activities;

•

additional borrowings to fund the Mills-related loans; and

•

the full year effect of May, August, and December 2006 senior note offerings.

            Also impacting interest expense was the consolidation of Town Center at Cobb, Gwinnett Place, and Mall of Georgia as a result of our acquisition of additional ownership interests, and the assumption of debt related to the acquisition of Las Americas Premium Outlets.

            Income tax expense of taxable REIT subsidiaries decreased $22.7 million due primarily to a $19.5 million tax benefit recognized related to the impairment charge related to our write-off of our entire investment in Surprise Grand Vista JV I, LLC, which is developing land located in Phoenix, Arizona, along with a reduction in the taxable income for the management company as a result of structural changes made to our wholly-owned captive insurance entities.

            Income from unconsolidated entities decreased $72.7 million, due in part to the impact of the Mills transaction (net of eliminations). On a net income basis, our share of income from SPG-FCM approximates a net loss of $58.7 million for the year due to additional depreciation and amortization expenses on asset basis step-ups in purchase accounting approximating $102.2 million for the second through fourth quarters of 2007. Also contributing to the decrease is the prior year recognition of $15.6 million in income related to a beneficial interest that we held in 2006 in a regional mall entity. This beneficial interest was terminated in November 2006.

            In 2007, we recognized an impairment of $55.1 million related to our Surprise Grand Vista venture in Phoenix, Arizona. As described above, the charge to earnings resulted in a $19.5 million tax benefit, resulting in a net charge to earnings, before consideration of the limited partners' interest, of $35.6 million.

            We recorded a $92.0 million net gain on the sales of assets and interests in unconsolidated entities in 2007 primarily as a result of the sale of five assets in Poland by Simon Ivanhoe. In 2006, we recorded a gain related to the sale of a beneficial interest of $86.5 million, a $34.4 million gain on the sale of a 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.

            In 2007, the loss on sale of discontinued operations of $35.3 million represents the net loss upon disposition of five non-core properties consisting of three regional malls and two community/lifestyle centers.

            Preferred unit distribution requirements decreased $28.0 million as a result of the redemption of the Series G preferred units in the fourth quarter of 2007 and the Series F preferred units in the fourth quarter of 2006.

Liquidity and Capital Resources

            Because we generate revenues primarily from long-term leases, our financing strategy relies primarily on long-term fixed rate debt. We manage our floating rate debt to be at or below 15-25% of total outstanding indebtedness by negotiating interest rates for each financing or refinancing based on current market conditions. Floating rate debt currently comprises approximately 15% 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 $1.9 billion during 2008. In addition, the Credit Facility provides an alternative source of liquidity as our cash needs vary from time to time. Also, Simon Property recently declared a dividend for the first quarter of 2009 that it intends to pay in cash and shares of Simon Property's common stock, with the cash component limited to 10% on an aggregate basis. As a result, we would make a corresponding distribution to unitholders comprised of 10% cash, with the balance being paid with units. Paying 90% of the 2009 first quarter dividend, and as a result our distributions, in a form other than cash allows Simon Property to satisfy its REIT taxable income distribution requirement while enhancing financial flexibility and balance sheet strength.

            Our balance of cash and cash equivalents increased $271.6 million during 2008 to $773.5 million as of December 31, 2008. December 31, 2008 and 2007 balances include $29.8 million and $41.3 million, respectively, related to our co-branded gift card programs, which we do not consider available for general working capital purposes.

            On December 31, 2008, we had available borrowing capacity of approximately $2.4 billion under the Credit Facility, net of outstanding borrowings of $1.0 billion and letters of credit of $15.7 million. During 2008, the maximum amount outstanding under the Credit Facility was $2.6 billion and the weighted average amount outstanding was $1.4 billion. The weighted average interest rate was 3.49% for the year ended December 31, 2008. The Credit Facility is scheduled to mature on January 11, 2010, which we can extend for another year at our option.

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

            Our business model requires us to regularly access the debt and equity capital markets to raise funds for some of our acquisition activity, development and redevelopment capital, as well as to refinance many of our existing debt maturities. We are currently seeing significant turmoil in the capital markets. This has impacted access to debt and equity capital for many organizations, including ours. As demonstrated by recent financing activities (both secured and unsecured), we were able to successfully access capital in the third and fourth quarters of 2008; however, there is no assurance we will be able to do so on similar terms or conditions in future periods. We believe we have sufficient cash on hand and availability under the Credit Facility to address our debt maturities and capital needs through 2009.

Acquisition of The Mills Corporation by SPG-FCM

            On February 16, 2007, SPG-FCM, a 50/50 joint venture between one of our affiliates and funds managed by Farallon Capital Management, L.L.C. ("Farallon"), entered into a definitive merger agreement to acquire all of the outstanding common stock of Mills for $25.25 per common share in cash. The acquisition of Mills and its interests in the 36 properties that remain at December 31, 2008 was completed in April 2007. As of December 31, 2008, we and Farallon had each funded $650.0 million into SPG-FCM to acquire all of the common stock of Mills. As part of the transaction, we also made loans to SPG-FCM and Mills primarily at rates of LIBOR plus 270-275 basis points. These funds were used by SPG-FCM and Mills to repay loans and other obligations of Mills, including the redemption of preferred stock, during 2007. As of December 31, 2008, the outstanding balance of our loan to SPG-FCM was $520.7 million, and the average outstanding balance during the twelve month period ended December 31, 2008 of all loans made to SPG-FCM and Mills was approximately $534.1 million. During 2008 and 2007, we recorded approximately $15.3 million and $39.1 million in interest income (net of inter-entity eliminations) related to these loans, respectively. We also recorded fee income, including fee income amortization related to up-front fees on loans made to SPG-FCM and Mills, during 2008 and 2007 of approximately $3.1 million and $17.4 million (net of inter-entity eliminations), respectively, for providing refinancing services to Mills' properties and SPG-FCM. The existing loan facility to SPG-FCM bears a rate of LIBOR plus 275 basis points and matures on June 7, 2009, with three available one-year extensions. Fees charged on loans made to SPG-FCM and Mills are amortized on a straight-line basis over the life of the loan.

            The Mills acquisition involved the purchase of all Mills' outstanding shares of common stock and common units for approximately $1.7 billion (at $25.25 per share or unit), the assumption of $954.9 million of preferred stock, the assumption of a proportionate share of property-level mortgage debt, of which SPG-FCM's share approximated $3.8 billion, the assumption of $1.2 billion in unsecured loans provided by us, costs to effect the acquisition, and certain liabilities and contingencies, including an ongoing investigation by the Securities and Exchange Commission, for an aggregate purchase price of approximately $8 billion. SPG-FCM has completed its purchase price allocations for the Mills acquisition using valuations developed with the assistance of a third-party professional appraisal firm.

            In conjunction with the Mills acquisition, we acquired a majority interest in two properties in which we previously held a 50% ownership interest (Town Center at Cobb and Gwinnett Place) and as a result we have consolidated these two properties at the date of acquisition.

            In addition to the loans provided to SPG-FCM, we also provide management services to substantially all of the properties in which SPG-FCM holds an interest.

Cash Flows

            Our net cash flow from operating activities and distributions of capital from unconsolidated entities totaled $1.9 billion during 2008. In addition, we received net proceeds from our debt financing and repayment activities in 2008 of $764.8 million. These activities are further discussed below in "Financing and Debt". We also:

•

repurchased units and preferred units amounting to $17.9 million,

•

paid unitholder distributions totaling $1.0 billion,

•

paid preferred unit distributions totaling $58.7 million,

•

funded consolidated capital expenditures of $874.3 million. These capital expenditures include development costs of $327.7 million, renovation and expansion costs of $431.9 million, and tenant costs and other operational capital expenditures of $114.7 million and

•

funded investments in unconsolidated entities of $137.5 million.

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

Property's REIT qualification 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.

            We expect to generate positive cash flow from operations in 2009, and we consider these projected cash flows in our sources and uses of cash. These cash flows are principally derived from retail tenants, many of whom are experiencing considerable financial distress. A significant deterioration in projected cash flows from operations could cause us to increase our reliance on available funds from the Credit Facility, curtail planned capital expenditures, or seek other additional sources of financing as discussed above.

Financing and Debt

Unsecured Debt

            Our unsecured debt currently consists of $10.7 billion of senior unsecured notes and the Credit Facility. The Credit Facility bears interest at LIBOR plus 37.5 basis points and an additional facility fee of 12.5 basis points. The Credit Facility matures January 11, 2010 and may be extended one year at our option.

            On May 19, 2008, we issued two tranches of senior unsecured notes totaling $1.5 billion at a weighted average fixed interest rate of 5.74% consisting of a $700.0 million tranche with a fixed interest rate of 5.30% due May 30, 2013 and a second $800.0 million tranche with a fixed interest rate of 6.125% due May 30, 2018. We used proceeds from the offering to reduce borrowings on the Credit Facility and for general working capital purposes.

            On June 16, 2008, we completed the redemption of the $200.0 million outstanding principal amount of its 7% Mandatory Par Put Remarketed Securities, or MOPPRS. The redemption was accounted for as an extinguishment and resulted in a charge in the second quarter of 2008 of approximately $20.3 million.

            On August 28, 2008, we repaid a $150.0 million unsecured note, which had a fixed rate of 5.38%.

            During the year ended December 31, 2008, we drew amounts from the Credit Facility to fund the redemption of the remarketable debt securities and the repayment of the $150.0 million unsecured note. Other amounts drawn on the Credit Facility during the period were primarily for general working capital purposes. We repaid a total of $2.7 billion on the Credit Facility during the year ended December 31, 2008. The total outstanding balance of the Credit Facility as of December 31, 2008 was $1.0 billion, and the maximum amount outstanding during the year was approximately $2.6 billion. During the year ended December 31, 2008, the weighted average outstanding balance was approximately $1.4 billion. The amount outstanding as of December 31, 2008 includes $446.3 million in Euro and Yen-denominated borrowings. In addition, subsequent to December 31, 2008, we repaid $600 million in unsecured notes, consisting of two $300 million tranches that bore rates of 3.75% and 7.13%, respectively, using proceeds from the Credit Facility.

Secured Debt

            Total secured indebtedness was $6.3 billion and $5.3 billion at December 31, 2008 and 2007, respectively. During the twelve-month period ended December 31, 2008, we repaid $274.0 million in mortgage loans, unencumbering five properties.

            On January 15, 2008, we entered into a swap transaction that effectively converted $300.0 million of variable rate debt to fixed rate debt at a rate of 3.21%.

            On March 6, 2008, we borrowed $705 million on a term loan that matures March 5, 2012 and bears a rate of LIBOR plus 70 basis points. On May 27, 2008, the loan was increased to $735 million. This loan is secured by the cash flow distributed from six properties and has additional availability of $115 million through the maturity date.

            On July 30, 2008, we borrowed $190.0 million on a loan secured by Philadelphia Premium Outlets, which matures on July 30, 2014 and bears interest at a variable rate of LIBOR plus 185 basis points. On January 2, 2009, we executed a swap agreement that fixes the interest rate on this loan at 4.19%.

Table of Contents

            On September 23, 2008, we borrowed $170.0 million on a term loan that matures September 23, 2013 and bears interest at a rate of LIBOR plus 195 basis points. On November 4, 2008, the loan was increased to $220 million and on December 17, 2008, the loan was increased to its maximum availability of $260 million. This is a cross-collateralized loan that is secured by The Domain, Shops at Arbor Walk, and Palms Crossing. On January 2, 2009, we executed a swap agreement that fixes the interest rate on $200.0 million of this loan at 4.35%.

Summary of Financing

            Our consolidated debt, adjusted to reflect one fair value derivative outstanding at December 31, 2007 and the effect of fixing variable rate debt with interest rate swaps, and the effective weighted average interest rates for the years then ended consisted of the following (dollars in thousands):

            As of December 31, 2008, we had interest rate cap protection agreements on $281.8 million of consolidated variable rate debt. We also hold $505.0 million of notional amount variable rate swap agreements that have a weighted average fixed pay rate of 3.29% and a weighted average variable receive rate of 2.75%. As of December 31, 2008, the net effect of these agreements effectively converted $505.0 million of variable rate debt to fixed rate debt.

            Contractual Obligations and Off-balance Sheet Arrangements:    The following table summarizes the material aspects of our future obligations as of December 31, 2008 (dollars in thousands):

---

(1)

Represents principal maturities only and therefore, excludes net premiums and discounts of $17,199 and all required interest payments. We incurred interest expense during 2008 of $947.1 million, net of capitalized interest of $27.8 million.

(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

63

Table of Contents

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, 2008, we had loan guarantees and other guarantee obligations to support $71.9 million and $6.6 million, respectively, to support our total $6.6 billion share of joint venture mortgage and other indebtedness presented in the table above.

Preferred Unit Activity

            During 2008, the holders of 22,400 Series I preferred units exercised their rights to exchange the preferred units for shares of Simon Property's Series I preferred stock; we issued 5,151,776 Units to holders of Series I preferred units who exercised their conversion rights; we issued 1,187,238 units as a result of the conversion of 1,493,904 6% Convertible Perpetual Preferred Units; we issued 4,981 units as a result of the conversion of 6,583 7% Cumulative Convertible Preferred Units; and we redeemed 61,493 8% Cumulative Redeemable Preferred Units for cash.

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. If we determine it is in our best interests to purchase the joint venture interest and we believe we have adequate liquidity to execute the purchase without hindering our cash flows, then we may initiate these provisions or elect to buy. If we decide to sell any of our joint venture interests, we expect to use the net proceeds to reduce outstanding indebtedness or to reinvest in development, redevelopment, or expansion opportunities.

            Acquisitions.    The acquisition of high quality individual properties or portfolios of properties remains an integral component of our growth strategy. Effective January 1, 2008 we acquired an additional 1.8% interest in Oxford Valley Mall and Lincoln Plaza (which gives us a combined ownership interest in each of 64.99%). On September 12, 2008 we acquired an additional 3.2% interest in White Oaks Mall (which gives us an ownership interest of 80.68%). On December 31, 2008 we acquired an additional 5% interest in Gateway Shopping Center for $2.6 million (which gives us 100% interest in the asset).

            Dispositions.    We continue to pursue the sale of properties that no longer meet our strategic criteria or that are not the primary retail venue within their trade area. On December 30, 2008, the joint venture partnership in which we own a 50% interest sold Cincinnati Mills for $8.3 million. No material gain or loss was recorded on this disposition. There were no other dispositions of properties during the year ended December 31, 2008.

Development Activity

            New Domestic Developments.    Given the significant downturn in the economy, we have substantially reduced our development spending. We expect to complete construction on Cincinnati Premium Outlets, a 400,000 square foot upscale manufacturers' outlet center located in Monroe, OH, during the third quarter of 2009. The estimated total cost of this project is $92 million, and the carrying amount of the construction in progress as of December 31, 2008 was $43 million. We expect to fund this project with available cash flow from operations and borrowings from the Credit Facility.

            Strategic Domestic Expansions and Renovations.    In addition to new development, we incur costs to renovate and/or expand selected properties. Current projects include a 600,000 square foot Phase II expansion at The Domain, a 220,000 square foot expansion of Camarillo Premium Outlets — The Promenade at, and the addition of Nordstrom and small shops at South Shore Plaza. We expect to fund these capital projects with available cash flow from operations and borrowings from the Credit Facility. We expect to invest a total of approximately $300 million (our share) on expansion and renovation activities in 2009.

Capital Expenditures on Consolidated Properties.

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

            International Development Activity.    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 Centers in Japan and Mexico where we use Yen and Peso denominated financing, respectively. We expect our share of international development costs for 2009 will be approximately $140 million. We expect international development and redevelopment/expansion activity for 2009 to include:

•

continuing construction by Gallerie Commerciali Italia, or GCI, on two shopping centers: one in Naples, and one in Sicily with a total gross leasable area, or GLA, of 942,000 square feet.



•

completing and opening of Ami Premium Outlets Phase 1, a 227,000 square foot Premium Outlet Center located in Japan. We hold a 40% ownership interest in this property.



•

completing and opening three additional Wal-Mart anchored shopping centers, all located in China. We hold a 32.5% ownership interest in these centers.

            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 international 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 GCI, as of December 31, 2008, including all related components of other comprehensive income, was $224.2 million. Our investments in Simon Ivanhoe and GCI are accounted for using the equity method of accounting. Currently two European developments are under construction which will add approximately 942,000 square feet of GLA for a total net cost of approximately €221 million, of which our share is approximately €53 million, or $74.8 million based on current Euro:USD exchange rates.

            On October 20, 2005, Ivanhoe Cambridge, Inc., or 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 2006 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. As a result of these transactions, we and Ivanhoe each own a 50% interest in Simon Ivanhoe at December 31, 2007 and 2008.

            As of December 31, 2008, the carrying amount of our 40% joint venture investment in the seven Japanese Premium Outlet Centers including all related components of other comprehensive income was $312.6 million. Currently, Ami Premium Outlets, a 227,000 square foot Premium Outlet Center, is under construction in Ami, Japan. The project's total projected net cost is JPY 15.5 billion, of which our share is approximately JPY 6.2 billion, or $68.5 million based on applicable Yen:USD exchange rates.

            As of December 31, 2008, the carrying amount of our 32.5% joint venture investment in GMI including all related components of other comprehensive income was $53.9 million. Currently, one center is open in Changshu, China and three additional centers are under development. The three centers under development will add approximately 1.5 million square feet of GLA for a total net cost of approximately CNY 1.6 billion, of which our share is approximately CNY 523 million, or $76.8 million based on applicable CNY:USD exchange rates.

            During 2008, we acquired shares of stock of Liberty International, PLC, or Liberty. Liberty operates regional shopping centers and is the owner of other prime retail assets throughout the U.K. Liberty is a U.K. FTSE 100 listed company, with shareholders' funds of £4.7 billion and property investments of £8.6 billion, of which its U.K. regional shopping centers comprise 75%. Assets of the group under control or joint control amount to £11.0 billion. Liberty converted into a U.K. Real Estate Investment Trust (REIT) on January 1, 2007. Our interest in Liberty is less than 5% of their shares and is adjusted to their quoted market price, including a related foreign exchange component.

Distributions and Stock Repurchase Program

            On January 30, 2009, Simon Property's Board of Directors approved a quarterly common stock dividend of $0.90 per share, to be paid in a combination of cash and shares of its common stock. The distribution rate on our units is equal to the dividend rate on Simon Property's common stock. While our unitholders will have the right to elect to receive their distribution in either cash or units, we have announced that the aggregate cash component of the distribution will not exceed 10% of the total distribution, or $0.09 per unit. If the number of unitholders electing to receive cash would result in the payment of cash in excess of this 10% limitation, we will allocate the cash payment on a pro rata basis among those unitholders making the cash election. Simon Property has reserved the right to elect to pay the first quarter dividend, and as a result our distribution, all in cash. Simon Property's Board of Directors reviews and approves Simon Property's dividends and, as a result, our distributions, on a quarterly basis, and no determination has been made about whether the remaining 2009 distributions will be paid in a similar combination of cash and common stock. Paying all or a portion of its remaining 2009 dividends in a combination of cash and common stock allows Simon Property to satisfy its REIT taxable income distribution requirement under existing IRS revenue procedures, while enhancing financial flexibility and balance sheet strength.

            Distributions during 2008 aggregated $3.60 per unit and distributions during 2007 aggregated $3.36 per unit all paid in cash. We must pay a minimum amount of distributions to maintain Simon Property's status as a REIT. Our distributions typically exceed our net income generated in any given year primarily because of depreciation, which is a "non-cash" expense. Future distributions will be determined by the Simon Property Board of Directors based on actual results of operations, cash available for distributions, and what may be required to maintain Simon Property's status as a REIT.

            On July 26, 2007, Simon Property's Board of Directors authorized a stock repurchase program under which Simon Property may purchase up to $1.0 billion of its common stock over the next twenty-four months as market conditions warrant. Simon Property may repurchase the shares in the open market or in privately negotiated transactions. During 2008, no purchases were made as part of this program. The program had remaining availability of approximately $950.7 million at December 31, 2008. As Simon Property repurchases shares under this program, we repurchase an equal number of our units from Simon Property.

Forward-Looking Statements

            Certain statements made in this section or elsewhere in this report may be deemed "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Although we believe the expectations reflected in any forward-looking statements are based on reasonable assumptions, we can give no assurance that our expectations will be attained, and it is possible that our actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks, uncertainties and other factors. Such factors include, but are not limited to: the impact of a prolonged recession, our ability to meet debt service requirements, the availability and terms of financing, changes in our credit rating, changes in market rates of interest and foreign exchange rates for foreign currencies, 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, 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, competitive market forces, risks related to international activities, insurance costs and coverage, terrorist activities, and maintenance of our status as a real estate investment trust. We discuss these and other risks and uncertainties under the heading "Risk Factors" in our most recent Annual Report on Form 10-K. We may update that discussion in subsequent Quarterly Reports on Form 10-Q, but otherwise we undertake no duty or obligation to update or revise these forward-looking statements, whether as a result of new information, future developments, or otherwise.

Item 9A.    Controls and Procedures

            Evaluation of Disclosure Controls and Procedures.    We carried out an evaluation under the supervision and with participation of management, including Simon Property's chief executive officer and chief financial officer, of the effectiveness of the design and operation of our disclosure controls and procedures as of the end of the period covered by this Annual Report on Form 10-K pursuant to Exchange Act Rule 13a-15. Based upon that evaluation, our management, including the chief executive officer and chief financial officer, concluded that our disclosure controls and procedures were effective as of December 31, 2008.

            Changes in Internal Control Over Financial Reporting.    There was no change in our internal control over financial reporting (as defined in Rule 13a-15(f)) that occurred during the fourth quarter of 2008 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

            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, Simon Property's Board of Directors, principal executive and principal financial officers and effected by Simon Property's 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 assets;



•

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, 2008. 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, 2008, our internal control over financial reporting is effective based on those criteria.

            Our independent registered public accounting firm has issued an audit report on their assessment of our internal control over financial reporting. Their report is included within Item 9A of this Form 10-K.

Report Of Independent Registered Public Accounting Firm

The Board of Directors of Simon Property Group, Inc.
and The Partners of Simon Property Group, L.P.:

            We have audited Simon Property Group, L.P. and Subsidiaries' internal control over financial reporting as of December 31, 2008 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, L.P. 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 included in the accompanying Management's Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Partnership'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, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, 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.

            In our opinion, Simon Property Group, L.P. and Subsidiaries maintained, in all material respects, effective internal control over financial reporting as of December 31, 2008, based on the COSO criteria.

            We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), the consolidated balance sheets of Simon Property Group, L.P. and Subsidiaries as of December 31, 2008 and 2007, and the related consolidated statements of operations and comprehensive income, partners' equity and cash flows for each of the three years in the period ended December 31, 2008 of Simon Property Group, L.P. and Subsidiaries, and the financial statement schedule listed in the Index at Item 15, and our report dated February 25, 2009 expressed an unqualified opinion thereon.

Item 9B.    Other Information

Report of Independent Registered Public Accounting Firm

The Board of Directors of Simon Property Group, Inc.
and The Partners of Simon Property Group, L.P.:

            We have audited the accompanying consolidated balance sheets of Simon Property Group, L.P. and Subsidiaries as of December 31, 2008 and 2007, and the related consolidated statements of operations and comprehensive income, partners' equity and cash flows for each of the three years in the period ended December 31, 2008. Our audit also included the financial statement schedule listed in the Index at Item 15. These financial statements and schedule are the responsibility of the Partnership's management. Our responsibility is to express an opinion on these financial statements and schedule based on our audits.

            We conducted our audits 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 the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

            In our opinion, the financial statements referred to above present fairly, in all material respects, the consolidated financial position of Simon Property Group, L.P. and Subsidiaries at December 31, 2008 and 2007, and the consolidated results of their operations and their cash flows for each of the three years in the period ended December 31, 2008, in conformity with U.S. generally accepted accounting principles. Also, in our opinion, the related financial statement schedule, when considered in relation to the basic financial statements taken as a whole, presents fairly in all material respects the information set forth therein.

            We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States), Simon Property Group, L.P. and Subsidiaries' internal control over financial reporting as of December 31, 2008, based on criteria established in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 25, 2009, expressed an unqualified opinion thereon.

(Dollars in thousands, except unit and per unit amounts and where indicated as in millions or billions)

1.    Organization

            Simon Property Group, L.P. is a Delaware limited partnership and the majority-owned subsidiary of Simon Property Group, Inc. In these notes to consolidated financial statements, the terms "Operating Partnership", "we", "us" and "our" refer to Simon Property Group, L.P., and its subsidiaries and the term "Simon Property" refers to Simon Property Group, Inc. Simon Property is a self-administered and self-managed real estate investment trust ("REIT") under the Internal Revenue Code of 1986, as amended (the "Code"). Pursuant to our partnership agreement, we are required to pay all expenses of Simon Property.

            We own, develop, and manage retail real estate in five retail real estate platforms: regional malls, Premium Outlet Centers®, The Mills®, community/lifestyle centers, and international properties. As of December 31, 2008, we owned or held an interest in 324 income-producing properties in the United States, which consisted of 164 regional malls, 16 additional regional malls and four additional community centers acquired as a result of the 2007 acquisition of The Mills Corporation, or the Mills acquisition, 70 community/lifestyle centers, 16 The Mills, 40 Premium Outlet Centers, and 14 other shopping centers or outlet centers in 41 states and Puerto Rico. We also own interests in four parcels of land held in the United States for future development. Internationally, we have ownership interests in 52 European shopping centers (France, Italy, and Poland); seven Premium Outlet Centers in Japan; one Premium Outlet Center in Mexico; one Premium Outlet Center in Korea; and one shopping center in China. Also, through joint venture arrangements we have ownership interests in the following properties under development internationally: a 24% interest in two shopping centers in Italy, a 40% interest in a Premium Outlet Center in Japan, and a 32.5% interests in three additional shopping centers under construction in China.

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

•

Base minimum rents,

•

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 grow by generating supplemental revenues from the following activities:

•

Establishing our malls as leading market resource providers for retailers and other businesses and consumer-focused corporate alliances, including: payment systems (including handling fees relating to the sales of bank-issued prepaid cards), national marketing alliances, static and digital media initiatives, business development, sponsorship, and events,

•

Offering property operating services to our tenants and others, including: waste handling and facility services, as well as major capital expenditures such as roofing, parking lots and energy systems,

•

Selling or leasing land adjacent to our shopping center properties, commonly referred to as "outlots" or "outparcels," and

•

Generating interest income on cash deposits and loans made to related entities.

2.    Basis of Presentation and Consolidation

            The accompanying consolidated financial statements 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.

Notes to Consolidated Financial Statements (Continued)

(Dollars in thousands, except unit and per unit amounts and where indicated as in millions or billions)

2.    Basis of Presentation and Consolidation (Continued)

            We also consolidate all variable interest entities, or VIE, when we are determined to be the primary beneficiary. Our determination of the primary beneficiary of a VIE considers all relationships between us and the VIE, including management agreements and other contractual arrangements, when determining the party obligated to absorb the majority of the expected losses, as defined in FASB Interpretation No. 46 (revised), Consolidation of Variable Interest Entities (FIN 46(R)). There have been no changes during 2008 in conclusions about whether an entity qualifies as a VIE or whether we are the primary beneficiary of any previously identified VIE. During 2008, we have not provided financial or other support to a previously identified VIE that we were not previously contractually obligated to provide.

            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.

            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, 2008, we consolidated 203 wholly-owned properties and consolidated 18 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 165 properties using the equity method of accounting (joint venture properties). We manage the day-to-day operations of 93 of the 165 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. Additionally, we account for our investment in SPG-FCM Ventures, LLC, or SPG-FCM, which acquired The Mills Corporation and its majority-owned subsidiary, The Mills Limited Partnership, or collectively Mills, in April 2007, using the equity method of accounting. We have determined that SPG-FCM is not a VIE and that Farallon Capital Management, L.L.C., or Farallon, our joint venture partner, has substantive participating rights with respect to the assets and operations of SPG-FCM pursuant to the applicable partnership agreements.

            We allocate our net operating results after preferred distributions based on our partners' respective ownership. In addition, Simon Property owns series of our preferred units that have terms comparable to outstanding shares of Simon Property preferred stock. Simon Property's weighted average ownership interest in us was as follows:

            As of December 31, 2008 and 2007, Simon Property's ownership interest was 80.4% and 79.4%, respectively. We adjust the limited partners' interest at the end of each period to reflect their ownership interest. Preferred distributions 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 allocable 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 capitalize interest on projects during periods of construction until the projects are ready for their intended purpose based on interest rates in place during the construction period. The amount of interest capitalized during each year is as follows:

            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 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.

            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.

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 Statement of Financial Accounting Standards (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.

(Dollars in thousands, except unit and per unit amounts and where indicated as in millions or billions)

3.    Summary of Significant Accounting Policies (Continued)

            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. 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.

Discontinued Operations

            SFAS No. 144, "Accounting for the Impairment or Disposal of Long-Lived Assets" (SFAS 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 144 requires us to reclassify any material operations related to consolidated properties sold during the period to discontinued operations. During 2007, we reported the net loss upon sale on our five consolidated assets sold in "loss on sale of discontinued operations" in the consolidated statements of operations and comprehensive income. The operating results of the assets disposed of in 2007 were not significant to our consolidated results of operations. There were no consolidated assets sold during 2008.

Cash and Cash Equivalents

            We consider all highly liquid investments purchased with an original maturity of 90 days or less to be cash and cash equivalents. Cash equivalents are carried at cost, which approximates fair value. Cash equivalents generally consist of commercial paper, bankers acceptances, Eurodollars, repurchase agreements, and money markets. Our gift card programs are administered by banks. 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, 2008 and 2007, includes a balance of $29.8 million and $41.3 million, respectively, related to these gift card programs which we do not consider available for general working capital purposes. Financial instruments that potentially subject us to concentrations of credit risk include our cash and cash equivalents and our trade accounts receivable. We place our cash and cash equivalents with institutions with high credit quality. However, at certain times, such cash and cash equivalents may be in excess of FDIC and SIPC insurance limits. See Notes 4, 8, and 10 for disclosures about non-cash investing and financing transactions.

Marketable and Non-Marketable Securities

            Marketable securities consist primarily of the investments of our captive insurance subsidiaries, our investment in shares of stock of Liberty International PLC, or Liberty, our deferred compensation plan investments, and certain investments held to fund the debt service requirements of debt previously secured by investment properties that have been sold. Non-marketable securities includes an investment that we acquired in 2008.

            The types of securities included in the investment portfolio of our captive insurance subsidiaries typically include U.S. Treasury or other U.S. government securities as well as corporate debt securities with maturities ranging from 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, which approximates fair value, held by our captive insurance subsidiaries is adjusted for amortization of premiums and accretion of discounts to maturity. Our investment in Liberty is also accounted for as an available-for-sale security. Liberty operates regional shopping centers and is owner of other retail assets throughout the U.K. Liberty is a U.K. FTSE 100 listed company. Liberty converted into a U.K. Real Estate Investment Trust (REIT) on January 1, 2007. Our interest in Liberty is less than 5% of their shares and is adjusted to their quoted market price, including a related foreign exchange component. Changes in the values of these securities are recognized in accumulated other comprehensive income (loss) until the gain or loss is realized and recorded in other income, and includes the effect of changes in foreign exchange rates on foreign currency denominated investments. However, if we determine a decline

3.    Summary of Significant Accounting Policies (Continued)

in value is other than temporary, then we recognize the unrealized loss in earnings 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 these securities may be limited. Our deferred compensation plan investments are classified as trading securities and are valued based upon quoted market prices. The investments have a matching liability recorded as the amounts are fully payable to the employees that earned the compensation. Changes in the values of these securities are recognized in earnings, but because of the matching liability the impact to net income is zero. As of December 31, 2008 and 2007, we have investments of $53.4 million and $55.9 million, respectively, which must be used to fund the debt service requirements of debt related to investment properties sold. These investments are classified as held-to-maturity and are recorded at amortized cost as we have the ability and intent to hold these investments to maturity. During 2008, we made an investment of $70 million in a non-marketable security that we account for under the cost method. To the extent an other-than-temporary decline in fair value is deemed to have occurred, we would adjust this investment to its fair value.

Fair Value Measurements

            We hold marketable securities that total $316.7 million and $260.4 million at December 31, 2008 and 2007, respectively, and are considered to have Level 1 fair value inputs. The underlying aggregate unrealized loss on our marketable securities as of December 31, 2008 was $165.3 million. In addition, we have derivative instruments, primarily interest rate swap agreements, with a gross liability balance of $19.4 million and $6.8 million, at December 31, 2008 and 2007, respectively, which are classified as having Level 2 inputs. As defined by Statement of Financial Accounting Standard No. 157, "Fair Value Measurements" (SFAS 157), Level 1 fair value inputs are quoted prices for identical items in active, liquid and visible markets such as stock exchanges, and Level 2 fair value inputs include observable information for similar items in active or inactive markets. We appropriately consider counterparty creditworthiness in the valuations.

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, or 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" 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, 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 which is included in "gain on sale of assets and interests in unconsolidated entities" in the consolidated statements of operations and comprehensive income.

Use of Estimates

            We prepared the accompanying consolidated financial statements in accordance with accounting principles generally accepted in the United States, or 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.

Segment Disclosure

            SFAS No. 131, "Disclosures about Segments of an Enterprise and Related Information" (SFAS 131) requires disclosure of certain operating and financial data 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, The Mills, 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:

            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. Details of these deferred costs as of December 31 are as follows:

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

            Intangible Assets.    The average life of in-place lease intangibles is approximately 5.5 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 2 years. The unamortized amounts of below market leases are included in accounts payable, accrued expenses, intangibles and deferred revenues on the consolidated balance sheets were $94.3 million and $146.7 million as of December 31, 2008 and 2007, respectively. The amount of amortization of above and below market leases, net for the year ended December 31, 2008, 2007, and 2006 was $35.4 million, $44.6 million, and $53.3 million, respectively. If a lease is terminated prior to the original lease termination, any remaining unamortized intangible is charged to the income statement.

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

            Estimated future amortization, and the increasing (decreasing) effect on minimum rents for our above and below market leases recorded as of December 31, 2008 are as follows:

3.    Summary of Significant Accounting Policies (Continued)

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 associated with our indebtedness and interest payments as described in Note 8 and record all derivatives on our balance sheets at fair value. We require that hedging derivative instruments be highly 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 other 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 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 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 Other Comprehensive Income (Loss)

            The components of our accumulated other comprehensive income (loss) consisted of the following as of December 31:

            Included in cumulative translation adjustment is the gain related to the impact of exchange rate fluctuations on foreign currency denominated debt of $46.9 million and $35.4 million at December 31, 2008 and 2007, respectively, that hedges the currency exposure related to certain of our foreign investments. The net unrealized losses as of December 31, 2008 of $165.3 million represents the valuation and related currency adjustments for our marketable securities, including our investment in Liberty. We do not consider the decline in value of any of our marketable securities to be an other-than-temporary decline in value as these market value declines have existed for a short period of time, and we have the ability and intent to hold these securities. Further, as it relates to Liberty, we believe their underlying operating fundamentals remain substantially unchanged.

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 exceed 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, or CAM, real estate taxes and insurance. This significantly reduces our exposure to increases in costs and operating expenses resulting from inflation. 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. For approximately 75% of our leases in the U.S. regional mall portfolio, we receive a fixed payment from the tenant for the CAM component. We are continually working towards converting the remainder of our leases to the fixed payment methodology. Without the fixed-CAM component, CAM expense reimbursements are based on the tenant's proportionate share of the allocable operating expenses and CAM capital expenditures for the property. 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 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 earned based on a contractual percentage of joint venture property revenue. Development fee revenue is earned on a contractual percentage of hard costs to develop a property. Leasing fee revenue is earned on a contractual per square foot charge based on the square footage of current year leasing activity. We recognize revenue for these services provided when earned based on the underlying 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 third-party actuaries and management's best estimates. Total insurance reserves for our insurance subsidiaries and other self-insurance programs as of December 31, 2008 and 2007 approximated $116.5 million and $121.4 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.

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. Accounts are written off when they are deemed to be no

longer collectible. Presented below is the activity in the allowance for credit losses and includes the activities related to discontinued operations during the following years:

Income Taxes

            As a partnership, the allocated share of our income or loss for each year is included in the income tax returns of the partners; accordingly, no accounting for income taxes is required in the accompanying consolidated financials statements. State income, franchise or other taxes were not significant in any of the periods presented.

            Simon Property and two of our subsidiaries are taxed as REITs under Sections 856 through 860 of the Internal Revenue Code and applicable Treasury regulations relating to REIT qualification. In order to maintain this REIT status, the regulations require each REIT to distribute at least 90% of its taxable income to stockholders and meet certain other asset and income tests as well as other requirements. We intend to continue to make distributions to Simon Property and to assist Simon Property in meeting the asset and income tests and other REIT requirements in order to allow it to adhere to these requirements and maintain its REIT status. Our subsidiary REIT 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 either of our REIT subsidiaries fail to qualify as a REIT, Simon Property or that entity will be subject to tax at regular corporate rates for the years in which it failed to qualify. If Simon Property lost its REIT status, it could not elect to be taxed as a REIT for four years unless its failure to qualify was due to reasonable cause and certain other conditions were satisfied.

            Simon Property has also elected taxable REIT subsidiary, or 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, 2008 and 2007, we had a net deferred tax asset of $8.9 million and $19.8 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. No valuation allowance has been recorded as we believe these amounts will be realized. State income, franchise or other taxes were not significant in any of the periods presented. The income tax benefit in 2007 results primarily from the tax deductibility of a $55.1 million impairment charge.

3.    Summary of Significant Accounting Policies (Continued)

Reclassifications

            We made certain reclassifications of prior period amounts in the financial statements to conform to the 2008 presentation. The reclassifications were to amounts reported in the consolidated statement of cash flows and had no impact on previously reported operating results.

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 consolidated acquisition and disposal activity for the periods presented are highlighted as follows:

2008 Acquisitions

            Effective January 1, 2008, we acquired additional interests in three existing consolidated properties of between 1.8% and 5%, for an aggregate $6.2 million in cash. Two of the properties continue to have a minority interest holder. We now own 100% of the third property.

2007 Acquisitions

            As a result of the Mills acquisition which is more fully discussed in Note 7, we consolidated two regional mall properties, Town Center at Cobb and Gwinnett Place. In addition to the Mills acquisition, on March 1, 2007, we acquired the remaining 40% interest in both University Park Mall and University Center located in Mishawaka, Indiana from our partner and as a result, we now own 100% of these properties. On March 28, 2007, we acquired The Maine Outlet, a 112,000 square foot outlet center located in Kittery, Maine, adjacent to our Kittery Premium Outlets property. On August 23, 2007, we acquired Las Americas Premium Outlets, a 560,000 square foot upscale outlet center located in San Diego, California. We also purchased an additional 1% interest in Bangor Mall on July 13, 2007, and an additional 6.5% interest in Montgomery Mall on November 1, 2007. The aggregate purchase price of the consolidated assets acquired during 2007, excluding Town Center and Cobb and Gwinnett Place, was approximately $394.2 million, including the assumption of our share of debt of the properties acquired.

2006 Acquisitions

            On November 1, 2006, we acquired the remaining 50% interest in Mall of Georgia, a regional mall property 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.

2008 Dispositions

            We had no consolidated property dispositions during the year ended December 31, 2008.

2007 Dispositions

            During the year ended December 31, 2007, we sold five consolidated properties for which we received net proceeds of $56.4 million and recorded our share of a loss on the disposals (net) totaling $35.3 million.

4.    Real Estate Acquisitions, Disposals, and Impairment (Continued)

2006 Dispositions

            During the year ended December 31, 2006, we sold 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 dispositions totaling $12.2 million.

            Impairment.    In 2008, we recorded an impairment charge of $21.2 million. This resulted primarily from a $10.5 million reduction in the carrying value of a regional mall to its estimated net realizable value and the write-off of predevelopment costs related to various projects that we no longer plan to pursue development.

5.    Per Unit Data

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

            For the year ending December 31, 2008, potentially dilutive securities include Simon Property stock options, convertible preferred stock and certain series of our preferred units The only security that had a dilutive effect for the years ended December 31, 2008, 2007 and 2006 were Simon Property stock options.

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

6.    Investment Properties

            Investment properties consist of the following as of December 31:

7.    Investments in Unconsolidated Entities

            Joint ventures are common in the real estate industry. We use joint ventures, primarily with institutional investors, to finance properties, develop new properties, and diversify our risk in a particular property or portfolio. We held joint venture ownership interests in 103 properties in the U.S. as of December 31, 2008 and December 31, 2007. We also held interests in two joint ventures which owned 52 European shopping centers as of December 31, 2008 and 51 as of December 31, 2007. We also held an interest in seven joint venture properties under operation in Japan, one joint venture property in Mexico, one joint venture property in Korea, and one joint venture property in China. We account for these joint venture 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.

Acquisition of The Mills Corporation by SPG-FCM

            On February 16, 2007, SPG-FCM, a 50/50 joint venture between one of our affiliates and funds managed by Farallon Capital Management, L.L.C., or Farallon, entered into a definitive merger agreement to acquire all of the outstanding common stock of Mills for $25.25 per common share in cash. The acquisition of Mills and its interests in the 36 properties that remain at December 31, 2008 was completed in April 2007. As of December 31, 2008, we and Farallon had each funded $650.0 million into SPG-FCM to acquire all of the common stock of Mills. As part of the transaction, we also made loans to SPG-FCM and Mills at rates of LIBOR plus 270-275 basis points. These funds were used by SPG-FCM and Mills to repay loans and other obligations of Mills, including the redemption of preferred stock, during 2007. As of December 31, 2008, the outstanding balance of our loan to SPG-FCM was $520.7 million, and the average outstanding balance during the year ended December 31, 2008 of all loans made to SPG-FCM and Mills was approximately $534.1 million. During 2008 and 2007, we recorded approximately $15.3 million and $39.1 million in interest income (net of inter- entity eliminations) related to these loans, respectively. We also recorded fee income, including fee income amortization related to up-front fees on loans made to SPG-FCM and Mills, during 2008 and 2007 of approximately $3.1 million and $17.4 million (net of inter-entity eliminations), respectively, for providing refinancing services to Mills' properties and SPG-FCM. The existing loan facility to SPG-FCM bears a rate of LIBOR plus 275 basis points and matures on June 7, 2009, with three available one-year extensions. Fees charged on loans made to SPG-FCM and Mills are amortized on a straight-line basis over the life of the loan.

7.    Investments in Unconsolidated Entities (Continued)

            As a result of the change in control of Mills, holders of Mills' Series F convertible cumulative redeemable preferred stock had the right to require the repurchase of their shares for cash equal to the liquidation preference per share plus accrued and unpaid dividends. During the second quarter of 2007, all of the holders of Mills' Series F preferred stock exercised this right, and Mills redeemed this series of preferred stock for approximately $333.2 million, including accrued dividends. Further, as of August 1, 2007, The Mills Corporation was liquidated and the holders of the remaining series' of Mills preferred stock were paid a liquidation preference of approximately $693.0 million, including accrued dividends.

            During the third quarter of 2007, the holders of less than 5,000 common units in the Mills' operating partnership, or Mills Units, received $25.25 in cash, and those holding 5,000 or more Mills Units had the option to exchange for cash of $25.25, or units of the Operating Partnership based on a fixed exchange ratio of 0.211 Operating Partnership units for each Mills Unit. That option expired on August 1, 2007. Holders electing to exchange received 66,036 units in the Operating Partnership for their Mills Units. The remaining Mills Units were exchanged for cash.

            Effective July 1, 2007, we or an affiliate of ours began serving as the manager for substantially all of the properties in which SPG-FCM holds an interest. In conjunction with the Mills acquisition, we acquired a majority interest in two properties in which we previously held a 50% ownership interest (Town Center at Cobb and Gwinnett Place) and as a result we have consolidated these two properties at the date of acquisition. We have reclassified the results of these properties in the Joint Venture Statement of Operations into "Income from consolidated joint venture interests."

            The Mills acquisition involved the purchase of all of Mills' outstanding shares of common stock and common units for approximately $1.7 billion (at $25.25 per share or unit), the assumption of $954.9 million of preferred stock, the assumption of a proportionate share of property-level mortgage debt, of which SPG-FCM's share approximated $3.8 billion, the assumption of $1.2 billion in unsecured loans provided by us, costs to effect the acquisition, and certain liabilities and contingencies, including an ongoing investigation by the Securities and Exchange Commission, for an aggregate purchase price of approximately $8 billion. SPG-FCM has finalized its purchase price allocations for the Mills acquisition. The valuations were developed with the assistance of a third-party professional appraisal firm.

            In addition we sold our interest in Cincinnati Mills and Broward and Westland Malls, which we acquired through the Mills acquisition, and recognized no gain or loss on these dispositions.

Joint Venture Property Refinancing Activity

            The following joint venture property refinancing activity occurred during the period, some of which resulted in our receiving significant excess refinancing proceeds or making contributions:

            On December 5, 2008, we refinanced Ontario Mills, a joint venture property in which we own a 25% interest, with a $75.0 million, LIBOR plus 296 basis points variable-rate mortgage that matures December 5, 2013. We subsequently entered into a swap agreement that essentially fixes the interest rate at 5.13%. The balances of the previous mortgages were $135.6 million and required a contribution by the partners to retire the loan. Our net share of the contribution was $15.7 million.

            During 2008, we refinanced Fashion Valley Mall, a joint venture property in which we own a 50% interest, with a $200.0 million, LIBOR plus 200 bps variable-rate mortgage that matures October 9, 2013. The balances of the two previous mortgages, which were repaid, were $153.6 million and $29.1 million and bore interest at a fixed rate of 6.49% and 6.58%, respectively. We received our share of the excess refinancing proceeds of approximately $7.1 million on the closing of the new mortgage loan.

            On October 1, 2008, we refinanced Mall of New Hampshire, a joint venture property in which we own a 49.14% interest, with a $136.7 million, 6.23% fixed-rate mortgage that matures October 5, 2015. The balances of the two previous mortgages, which were repaid, were $93.5 million and $7.8 million and bore interest at a fixed rate of 6.96%

and 8.53%, respectively. We received our share of the excess refinancing proceeds of approximately $18.7 million on the closing of the new mortgage loan.

            On November 15, 2007, we refinanced Aventura Mall, a joint venture property in which we own a 33.3% interest, with a $430.0 million, 5.905% fixed-rate mortgage that matures on December 11, 2017. The balance of the previous $200.0 million 6.61% fixed-rate mortgage was repaid, and we received our share of the excess refinancing proceeds of approximately $71.4 million.

            On November 1, 2007, we refinanced West Town Mall, a joint venture property in which we own a 50% interest, with a $210.0 million, 6.3375% fixed-rate mortgage that matures on December 1, 2017. The balance of the previous $76.0 million 6.90% fixed-rate mortgage was repaid, and we received our share of the excess refinancing proceeds of approximately $66.4 million.

Summary Financial Information

            A summary of our investments in joint ventures and share of income from such joint ventures follow. We condensed into separate line items major captions of the statements of operations for joint venture interests sold or consolidated. Consolidation occurs when we acquire an additional interest in the joint venture and as a result, gain control of the property or become the primary beneficiary of a VIE. We reclassified these line items into "Income from discontinued joint venture interests" and "Income from consolidated joint venture interests" so that we may present comparative results of operations for those joint venture interests held as of December 31, 2008. Balance sheet information for the joint ventures is as follows:

            "Excess Investment" represents the unamortized difference of our investment over our share of the equity in the underlying net assets of the joint ventures acquired. We amortize excess investment over the life of the related properties, typically no greater than 40 years, and the amortization is included in the reported amount of income from unconsolidated entities.

            This debt becomes due in installments over various terms extending through 2036 with interest rates ranging from 1.00% to 10.61% and a weighted average rate of 4.99% at December 31, 2008.

2006 Acquisition and Disposition Activity

            On November 1, 2006, we acquired the remaining 50% interest in Mall of Georgia, a regional mall property for $252.6 million, which includes 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 "Income from consolidated joint venture interests."

7.    Investments in Unconsolidated Entities (Continued)

            Impairment Charge.    On December 28, 2005, we invested $50.0 million of equity for a 40% interest in a joint venture with Toll Brothers, Inc. and Meritage Homes Corp. to purchase a 5,485-acre land parcel in northwest Phoenix from DaimlerChrysler Corporation for $312 million. The principal use of the land upon attaining entitled status is to develop single-family homesites by our partners. As a result of the downturn in the residential market, during the fourth quarter of 2007, we recorded an impairment charge of $55.1 million, $36.5 million net of tax benefit, representing our entire equity investment in this joint venture, including interest capitalized on our invested equity.

International Joint Venture Investments

            European Joint Ventures.    We conduct our international operations in Europe through our two European joint venture investment entities; Simon Ivanhoe S.à.r.l., or Simon Ivanhoe, and Gallerie Commerciali Italia, or GCI. The carrying amount of our total combined investment in these two joint venture investments is $224.2 million and $361.3 million as of December 31, 2008 and 2007, respectively, including all related components of other comprehensive income. We have a 50% ownership in Simon Ivanhoe and a 49% ownership in GCI as of December 31, 2008.

            On October 20, 2005, Ivanhoe Cambridge, Inc., or 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 (loss) on sales of assets and interests in unconsolidated entities, net" in the 2006 consolidated statement of operations and comprehensive income (loss). 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. As a result of these transactions, we and Ivanhoe each own a 50% interest in Simon Ivanhoe at December 31, 2007 and 2008.

            On July 5, 2007, Simon Ivanhoe completed the sale of five non-core assets in Poland and we presented our share of the gain upon this disposition in "gain (loss) on sale of assets and interests in unconsolidated entities, net" in the consolidated statement of operations and comprehensive income.

            Asian Joint Ventures.    We conduct our international Premium Outlet operations in Japan through joint ventures with Mitsubishi Estate Co., Ltd. and Sojitz Corporation. The carrying amount of our investment in these Premium Outlet joint ventures in Japan is $312.6 million and $273.0 million as of December 31, 2008 and 2007, respectively, including all related components of other comprehensive income. We have a 40% ownership in these Japan Premium Outlet Centers through a joint venture arrangement. During 2007, we also completed construction and opened our first Premium Outlet in Korea. As of December 31, 2008 and 2007 respectively, our investment in our Premium Outlet in Korea, for which we hold a 50% ownership interest, approximated $18.0 million and $23.1 million including all related components of other comprehensive income.

            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 we own a 32.5% interest in the joint venture entities, and a 32.5% ownership in the management operation overseeing these projects, collectively referred to as Great Mall Investments, Ltd., or GMI. During 2008, we completed construction and opened our first center in China, and have three additional centers under construction and due for completion in 2009. As of December 31, 2008 and 2007 respectively, our investment in our centers in China approximated $53.9 million and $33.7 million including all related components of other comprehensive income. Our projected total equity commitment upon completion for all four centers in China is $53.7 million.

8.    Indebtedness and Derivative Financial Instruments

            Our mortgages and other indebtedness, excluding the impact of derivative instruments except for our fair value interest rate swaps, consist of the following as of December 31:

            General.    At December 31, 2008, we have pledged 76 properties as collateral to secure related mortgage notes including 7 pools of cross-defaulted and cross-collateralized mortgages encumbering a total of 39 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 76 encumbered properties, indebtedness on 18 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 payment of a yield-maintenance premium or defeasance. As of December 31, 2008, we were in compliance with all our debt covenants.

            Some of our limited partners guarantee a portion of our consolidated debt through foreclosure guarantees. In total, 53 limited partners provide guarantees of foreclosure of $285.3 million of our consolidated debt at three 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 limited partner 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.

Unsecured Debt

            Our unsecured debt currently consists of $10.7 billion of senior unsecured notes and $1.0 billion outstanding under our $3.5 billion credit facility, or the Credit Facility. The Credit Facility bears interest at LIBOR plus 37.5 basis

points and an additional facility fee of 12.5 basis points. The Credit Facility is scheduled to mature on January 11, 2010, which we can extend for another year at our option.

            On May 19, 2008, we issued two tranches of senior unsecured notes totaling $1.5 billion at a weighted average fixed interest rate of 5.74% consisting of a $700.0 million tranche with a fixed interest rate of 5.30% due May 30, 2013 and a second $800.0 million tranche with a fixed interest rate of 6.125% due May 30, 2018. We used proceeds from the offering to reduce borrowings on the Credit Facility and for general working capital purposes.

            On June 16, 2008, we completed redemption of the $200.0 million outstanding principal amount of its 7% Mandatory Par Put Remarketed Securities, or MOPPRS. The redemption was accounted for as an extinguishment and resulted in a charge in the second quarter of 2008 of approximately $20.3 million.

            On August 28, 2008, we repaid a $150.0 million unsecured note, which had a fixed rate of 5.38%.

            During the year ended December 31, 2008, we drew amounts from the Credit Facility to fund the redemption of the remarketable debt securities and the repayment of the $150.0 million unsecured note. Other amounts drawn on the Credit Facility were primarily for general working capital purposes. We repaid a total of $2.7 billion on the Credit Facility during the year ended December 31, 2008. The total outstanding balance of the Credit Facility as of December 31, 2008 was $1.0 billion, and the maximum amount outstanding during the year was approximately $2.6 billion. During the year ended December 31, 2008, the weighted average outstanding balance of the Credit Facility was approximately $1.4 billion. The amount outstanding as of December 31, 2008 includes $446.3 million in Euro and Yen-denominated borrowings. In addition, subsequent to December 31, 2008, we repaid $600 million in unsecured notes, consisting of two $300 million tranches that bore rates of 3.75% and 7.13%, respectively, using proceeds from the Credit Facility.

Secured Debt

            The balance of fixed and variable rate mortgage notes was $6.3 billion and $5.3 billion as of December 31, 2008 and 2007, respectively. Of the 2008 amount, $5.3 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, 2008, we repaid $274.0 million in mortgage loans, unencumbering five properties.

            On January 15, 2008, we entered into a swap transaction that effectively converted $300.0 million of variable rate debt to fixed rate debt at a net rate of 3.21%.

            On March 6, 2008, we borrowed $705 million on a term loan that matures March 5, 2012 and bears interest at a rate of LIBOR plus 70 basis points. On May 27, 2008, the loan was increased to $735 million. This loan is secured by the cash flow distributed from six properties and has additional availability of $115 million through the maturity date.

            On July 30, 2008, we borrowed $190.0 million on a loan secured by Philadelphia Premium Outlets, which matures on July 30, 2014 and bears interest at a variable rate of LIBOR plus 185 basis points. On January 2, 2009, we executed a swap agreement that fixes the interest rate of this loan at 4.19%.

            On September 23, 2008, we borrowed $170.0 million on a term loan that matures September 23, 2013 and bears interest at a rate of LIBOR plus 195 basis points. On November 4, 2008, the loan was increased to $220 million and on December 17, 2008, the loan was increased to its maximum availability of $260 million. This is a cross- collateralized loan that is secured by The Domain, Shops at Arbor Walk, and Palms Crossing. On January 2, 2009, we executed a swap agreement that fixes the interest rate on $200.0 million of this loan at 4.35%.

8.    Indebtedness and Derivative Financial Instruments (Continued)

Debt Maturity and Other

            Our scheduled principal repayments on indebtedness as of December 31, 2008 are as follows:

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

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, 2008, we reflected the fair value of outstanding consolidated derivatives in other liabilities for $19.4 million. In addition, we recorded the benefits from our treasury lock and interest rate hedge agreements in accumulated other comprehensive loss and the unamortized balance of these agreements is $3.3 million as of December 31, 2008. The net deficit from terminated swap agreements is also recorded in accumulated other comprehensive loss and the unamortized balance is $3.4 million as of December 31, 2008. As of December 31, 2008, our outstanding LIBOR based derivative contracts consisted of:

•

interest rate cap protection agreements with a notional amount of $281.8 million that mature in May 2009 and July 2010, and



•

fixed-rate swap agreements with a notional amount of $505.0 million have a weighted average pay rate of 3.29% and a weighted average receive rate of 2.75%.

8.    Indebtedness and Derivative Financial Instruments (Continued)

            Within the next year, we expect to reclassify to earnings approximately $10.9 million of loss of the current balance held in accumulated other comprehensive loss. The amount of ineffectiveness relating to fair value and cash flow hedges recognized in income during the periods presented was not material.

            Our joint ventures may also enter into interest rate swaps or caps, which are recorded at fair value on the joint ventures' balance sheet. Included in our accumulated other comprehensive income (loss) as of December 31, 2008 and 2007 is our share of the joint ventures accumulated derivative gains or (losses) of $(19.6) million and $(5.8) million, respectively.

Fair Value of Financial Instruments

            The carrying value of our variable-rate mortgages and other loans approximates their fair values. We estimate the fair values of consolidated fixed-rate mortgages using cash flows discounted at current borrowing rates and other indebtedness using cash flows discounted at current market rates. We estimate the fair values of consolidated fixed-rate unsecured notes using quoted market prices, or, if no quoted prices are available, we use quoted market prices for securities with similar terms and maturities. 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:

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, 2008 are as follows:

            Approximately 0.6% of future minimum rents to be received are attributable to leases with an affiliate of one of our limited partners.

10.    Partners' Equity

            Mezzanine Equity.    Preferred units whose redemption is outside our control have been classified as temporary equity in the accompanying consolidated balance sheets. Such units are described in the following paragraph.

            7.75%/8.00% Cumulative Redeemable Preferred Units.    During 2003, in connection with the purchase of additional interest in Kravco, we issued 7.75%/8.00% Cumulative Redeemable Preferred Units that accrue cumulative distributions 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 January 1, 2010, and ending December 31, 2010, and 12% of the liquidation value thereafter. These distributions are payable quarterly in arrears. A holder may require us 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 our partners' equity. We 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, which we expect to be in 2009. 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.

Unit Issuances and Repurchases

            In 2008, eight limited partners exchanged 2,574,608 units for an equal number of shares of common stock of Simon Property. We issued an equal number of units to Simon Property, increasing its ownership interest in us.

            We issued 282,106 units to Simon Property related to employee and director stock options exercised during 2008. We used the net proceeds from the option exercises of approximately $11.9 million for general working capital purposes.

            On July 26, 2007, the Simon Property Board of Directors authorized a common stock repurchase program under which Simon Property may purchase up to $1.0 billion of its common stock over the next twenty-four months as market conditions warrant. Simon Property may purchase the shares in the open market or in privately negotiated transactions. During 2008, no purchases were made as part of this program. Simon Property's share repurchase program had remaining availability of approximately $950.7 million at December 31, 2008.

            Holders of our Series I 6% Convertible Perpetual Preferred Units had the right to convert these preferred units into units during the year ended December 31, 2008. A total of 6,437,072 Series I preferred units were converted into 5,151,776 units for the year then ended.

10.    Partners' Equity (Continued)

Preferred Units

            The following table summarizes the carrying values of each series of preferred units that were outstanding as of December 31:

            The following series of preferred units had previously issued units in years prior to 2007, but had no shares outstanding at the end of 2008 and 2007, and the authorized units for each series are as follows: Series B 6.5% Convertible Preferred Units (5,000,000 units); Series E 8.00% Cumulative Redeemable Preferred Units (1,000,000 units); Series F 8.75% Cumulative Redeemable Preferred Units (8,000,000 units); Series G 7.89% Cumulative Step-Up Premium Rate Convertible Preferred Units (3,000,000 units); and Series H Variable Rate Preferred Units (4,530,000 units), Series K Variable Rate Redeemable Preferred Units (8,000,000 units); and Series L Variable Rate Redeemable Preferred Units (6,000,000 units).

            Series C 7.00% Cumulative Convertible Preferred Units.    Each Series C 7.00% preferred unit has a liquidation value of $28.00 and accrues cumulative distributions at a rate of $1.96 annually, payable quarterly in arrears. The Series C preferred units are convertible at the holders' option on or after August 27, 2004, into either a like number of shares of 7.00% Cumulative Convertible Preferred Stock of Simon Property with terms substantially identical to the Series C preferred units or into our common units at a ratio of 0.75676 to one provided that the closing stock price of Simon Property common stock exceeds $37.00 for any three consecutive trading days prior to the conversion date. We may redeem the Series C preferred units at their liquidation value plus accrued and unpaid distributions on or after August 27, 2009, payable in units. In the event of the death of a holder of Series C preferred units, or the occurrence of certain tax triggering events, we may be required to redeem the Series C preferred units at their liquidation value payable at our option in either cash (the payment of which may be made in four equal annual installments) or common units. During 2008, holders converted 6,583 of the preferred units into 4,981 common units.

            Series D 8.00% Cumulative Redeemable Preferred Units.    Each Series D 8.00% preferred unit has a liquidation value of $30.00 and accrues cumulative distributions at a rate of $2.40 annually, which is payable quarterly in arrears. The Series D preferred units are each paired with one Series C preferred unit or the common units into which the Series C preferred units may be converted. We may redeem the Series D preferred units at their liquidation value plus accrued and unpaid distributions on or after August 27, 2009, payable in either new preferred units having the same terms as the Series D preferred units, except that the distribution coupon rate would be reset to a market rate, or in units. The Series D preferred units are convertible at the holder's option on or after August 27, 2004, into 8.00% Cumulative Redeemable Preferred Stock of Simon Property with terms substantially identical to the Series D preferred units. In the event of the death of a holder or the occurrence of certain tax triggering events, we may be

required to redeem the Series D preferred units owned by such holder at their liquidation value payable at our option in either cash (the payment of which may be made in four equal annual installments) or common units. During 2008, one holder redeemed 61,493 of the preferred units for $1.8 million.

            Series I 6% Convertible Perpetual Preferred Units.    On October 14, 2004, we issued 18,015,506 Series I 6% convertible perpetual preferred units as part of our acquisition of the Chelsea Property Group (Chelsea). Distributions are made quarterly, at an annual rate of 6% per unit. On or after October 14, 2009, we have the option to redeem the Series I preferred units, in whole or in part, for cash only at a liquidation preference of $50.00 per unit plus accumulated and unpaid distributions. However, if the redemption date falls between the record date and the distribution payment date, the redemption price will be equal to only the liquidation preference per unit, and will not include any amount of distributions declared and payable on the corresponding distribution 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 Series I preferred units are convertible into a number of fully paid and non-assessable common units upon the occurrence of a conversion triggering event. A conversion triggering event includes the following: (a) if we call the Series I preferred units for redemption; or, (b) if Simon Property is a party to a consolidation, merger, binding share exchange, or sale of all or substantially all of its assets; or, (c) if the closing sale price of Simon Property's 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. If the closing price condition is not met at the end of any fiscal quarter, then conversions are not permitted in the following fiscal quarter. If a holder of Series I preferred units converts its Series I preferred units into common units, then the holder may also elect to convert those units into common stock of Simon Property, on a one-for-one basis in accordance with our partnership agreement. The holder of Series I preferred units also has the option to exchange the Series I preferred units for an equal number of shares of Series I preferred stock of Simon Property; however, we may elect to pay cash in lieu of the conversion. In 2008, holders of Series I preferred units exchanged 22,400 Series I preferred units for an equal number of shares of Series I preferred stock of Simon Property. In prior years, 1,093,042 Series I preferred units were exchanged for an equal number of shares of Series I preferred stock of Simon Property. During 2008, we also issued 1,187,238 units as a result of the conversion of 1,493,904 Series I preferred units.

            As of December 31, 2008, the conversion trigger price of $77.88 was not met and, as a result, conversion of the Series I preferred units will not be permitted through March 31, 2009. A total of 6,437,072 Series I preferred units were converted into 5,151,776 units during 2008 as the conversion trigger price was met at the quarterly determination dates during 2008.

            Series J 8³/8% Cumulative Redeemable Preferred Units.    We issued this series of preferred units in 2004 to replace a series of Chelsea preferred units. Distributions accrue quarterly at an annual rate of 8³/8% per unit. We can redeem this series, in whole or in part, on and after October 15, 2027 at a redemption price of $50.00 per unit, plus accumulated and unpaid distributions. These preferred units were issued at a premium of $7,553 as of the date of our acquisition of Chelsea.

            7.5% Cumulative Redeemable Preferred Units.    We issued this series of preferred units in connection with the purchase of an additional interest in a joint venture. The preferred units accrue cumulative quarterly distributions at a rate of $7.50 annually. We may redeem the preferred units on or after November 10, 2013, unless there is the occurrence of certain tax triggering events such as death of the initial holder, 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 redemption price is the liquidation value ($100.00 per preferred unit) plus accrued and unpaid distributions, payable either in cash or shares of our common stock of Simon Property. In the event of the death of a holder of the preferred units, the occurrence of certain tax triggering events applicable to the holder, or on or after November 10, 2006, the holder may require us to redeem the preferred units at the same redemption price payable at our option in either cash or units.

10.    Partners' Equity (Continued)

            Notes Receivable from Former CPI Stockholders.    Notes receivable of $17,199 from stockholders of an entity we acquired in 1998 are reflected as a deduction from partners' 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, along with Simon Property, have a stock incentive plan (the "1998 Plan"), which provides for the grant of awards with respect to the equity of Simon Property during a ten-year period, in the form of options to purchase shares of Simon Property common stock ("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 Simon Property to sell shares to us, at fair value, sufficient to satisfy the exercising of stock options, and for Simon Property to purchase common units for cash in an amount equal to the fair market value of such shares issued on the exercise of stock options.

            Administration.    The 1998 plan is administered by Simon Property's Compensation Committee of the Board of Directors. The committee 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 its administration. Options granted to employees 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. Since 2001, Simon Property has not granted any options to employees, except for a series of reload options we assumed as part of a prior business combination.

            Automatic Awards For Eligible Directors.    Directors of Simon Property who are not employees or employees of affiliates of Simon Property ("Eligible Directors") receive automatic awards under the 1998 plan. Until 2003, these awards took the form of stock options. Since then, the awards have been shares of restricted stock of Simon Property.

            Each eligible director receives on the first day of the first calendar month following his or her initial election 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 stockholders, eligible directors who are re-elected receive an award of restricted stock having a value of $82,500. In addition, eligible directors who serve as chairpersons of the standing committees (excluding the Executive Committee) 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 also receives an annual restricted stock award having a value of $12,500. The restricted stock vests in full after one year.

            Once vested, the delivery of the shares of restricted stock (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 directors may vote and are entitled to receive dividends on the underlying shares; however, any dividends on the shares of restricted stock must be reinvested in shares of common stock and held in the deferred compensation plan until the shares of a restricted stock 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 partners' equity and subsequently amortized against our earnings over the vesting period. Through December 31, 2008

10.    Partners' Equity (Continued)

Exchange Rights

            Limited partners have the right to exchange all or any portion of their units for shares of Simon Property common stock on a one-for-one basis or cash, as selected by Simon Property. 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.

Unit Distributions

            On January 30, 2009, Simon Property's Board of Directors approved a quarterly common stock dividend of $0.90 per share, to be paid in a combination of cash and shares of its common stock. The distribution rate on our units is equal to the dividend rate on Simon Property's common stock. While our unitholders will have the right to elect to receive their distribution in either cash or units, we have announced that the aggregate cash component of the distribution will not exceed 10% of the total distribution, or $0.09 per unit. If the number of unitholders electing to receive cash would result in our payment of cash in excess of this 10% limitation, we will allocate the cash payment on a pro rata basis among those unitholders making the cash election. Simon Property has reserved the right to elect to pay the first quarter dividend, and as a result our distribution, all in cash. Simon Property's Board of Directors reviews and approves Simon Property's dividends and, as a result, our distributions, on a quarterly basis, and no determination has been made about whether the remaining 2009 dividends will be paid in a similar combination of cash and common stock. Paying all or a portion of its remaining 2009 dividends in a combination of cash and common stock allows Simon Property to satisfy its REIT taxable income distribution requirement under existing IRS revenue procedures, while enhancing financial flexibility and balance sheet strength.

11.    Commitments and Contingencies

Litigation

            As previously disclosed, for several years we have been defending actions brought by the Attorneys General of Massachusetts, New Hampshire and Connecticut in their respective state courts and similar litigation brought by other parties alleging that the sale of co-branded, bank-issued gift cards by our affiliate, SPGGC, Inc., at certain of our properties, violated state gift certificate and consumer protection laws. We previously reported the dismissal of the New Hampshire litigation. During the fourth quarter of 2008, the complaint in the Massachusetts litigation was dismissed and we settled the Connecticut litigation. The only remaining legal proceedings involving gift card sales are two purported class actions brought by private parties in New York. With the resolution of the remaining Attorneys General's actions in 2008, we no longer believe that the ultimate outcome of these related actions would have a material adverse effect on our financial position, results of operations or cash flows and, accordingly, we do not expect to report further developments in these actions.

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

Lease Commitments

            As of December 31, 2008, a total of 29 of the consolidated properties are subject to ground leases. The termination dates of these ground leases range from 2009 to 2090. These ground leases generally require us to make fixed annual rental payments, or a fixed annual rental plus a percentage rent component 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 as follows:

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

Insurance

            We maintain commercial general liability, fire, flood, extended coverage and rental loss insurance on all of our properties in the United States through wholly-owned captive insurance entities and other self-insurance mechanisms. Rosewood Indemnity, Ltd. and Bridgewood Insurance Company, Ltd. are our wholly-owned captive insurance subsidiaries, and have agreed to indemnify our general liability carrier for a specific layer of losses for the properties that are covered under these arrangements. 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 these captive insurance entities also provides initial coverage for property insurance and certain windstorm risks at the properties located in coastal windstorm locations.

            We currently maintain insurance coverage against acts of terrorism on all of our properties in the United States 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.

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, 2008, we had loan guarantees and other guarantee obligations of $71.9 million and $6.6 million, respectively, to support our total $6.6 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.

11.    Commitments and Contingencies (Continued)

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, The Mills, and community/lifestyle centers rely heavily upon anchor tenants like most retail properties. Four retailers occupied 532 of the approximately 1,376 anchor stores in the properties as of December 31, 2008. An affiliate of one of these retailers is one of our limited partners.

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, 2008 and 2007, the estimated settlement value of these non-controlling interests was approximately $130 million and $145 million, respectively. The minority interest amount recognized as a liability on the consolidated balance sheets related to these non-controlling interests was approximately $23 million as of December 31, 2008 and 2007.

12.    Related Party Transactions

            Our management company provides management, insurance, and other services to Melvin Simon & Associates, Inc., 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:

            During 2008 and 2007, we recorded interest income of $15.3 million and $39.1 million, respectively, and financing fee income of $3.1 million and $17.4 million, respectively, net of inter-entity eliminations, related to the loans that we have provided to Mills and SPG-FCM and lending financing services to those entities and the properties in which they hold an ownership interest.

13.    Recently Issued Accounting Pronouncements

            In December 2007, the FASB issued SFAS No. 141(R), "Business Combinations", (SFAS 141(R)), and SFAS No. 160, "Noncontrolling Interests in Consolidated Financial Statements"(SFAS 160). SFAS 141(R) requires an acquirer to measure the identifiable assets acquired, the liabilities assumed and any noncontrolling interest in the acquiree at their fair values on the acquisition date, with goodwill being the excess value over the net identifiable assets acquired, and that costs of acquisition be expensed as incurred. SFAS 160 clarifies that a noncontrolling interest in a subsidiary should be reported as equity in the consolidated balance sheet and the noncontrolling interest's share of

earnings is included in consolidated net income. The calculation of earnings per share will continue to be based on income amounts attributable to the parent. SFAS 141(R) and SFAS 160 are effective for financial statements issued for fiscal years beginning after December 15, 2008. Early adoption is prohibited. We do not expect the adoption of SFAS 141(R) or SFAS 160 will have a significant impact on our results of operations or financial position other than the reclassification of certain noncontrolling interests on a prospective and retrospective basis.

            In March 2008, the FASB issued SFAS No. 161, "Disclosures about Derivative Instruments and Hedging Activities — an amendment of FASB Statement No. 133." This statement amends and expands the disclosure requirements of SFAS 133. This statement is effective for fiscal years beginning after November 15, 2008, and interim periods within those fiscal years. We are in the process of determining the impact of adopting this statement.

14.    Quarterly Financial Data (Unaudited)

            Quarterly 2008 and 2007 data is summarized in the table below and, as disclosed in Note 3, the amounts have been reclassified from previously disclosed amounts in accordance with the discontinued operations provisions of SFAS No. 144 and reflect dispositions through December 31, 2008. Income from continuing operations, income from continuing operations per unit — Basic, and income from continuing operations per unit — Diluted as previously reported in the September 30, 2007 Form 10-Q were $227,532, $0.74, and $0.74, respectively, and are presented below as $236,470, $0.77, and $0.77, respectively. All other amounts previously reported are equal to the amounts reported below. Quarterly amounts may not equal annual amounts due to rounding.

Notes to Schedule III as of December 31, 2008

(Dollars in thousands)

(1)    Reconciliation of Real Estate Properties:

            The changes in real estate assets for the years ended December 31, 2008, 2007, and 2006 are as follows:

            The unaudited aggregate cost of real estate assets for federal income tax purposes as of December 31, 2008 was $18,390,068.

(2)    Reconciliation of Accumulated Depreciation:

            The changes in accumulated depreciation and amortization for the years ended December 31, 2008, 2007, and 2006 are as follows:

            Depreciation of our investment in buildings and improvements reflected in the consolidated statements of operations and comprehensive income is calculated over the estimated original lives of the assets as follows:

•

Buildings and Improvements — typically 10-40 years for the structure, 15 years for landscaping and parking lot, and 10 years for HVAC equipment.



•

Tenant Allowances and Improvements — shorter of lease term or useful life.

(3)

Initial cost generally represents net book value at December 20, 1993, except for acquired properties and new developments after December 20, 1993. Initial cost also includes any new developments that are opened during the current year. Costs of disposals of property are first reflected as a reduction to cost capitalized subsequent to acquisition.

(4)

Not developed/constructed by us or our predecessors. The date of construction represents the acquisition date.

(5)

Property initial cost for these properties is the cost at the date of consolidation for properties previously accounted for under the equity method of accounting. Accumulated depreciation amounts for properties consolidated which were previously accounted for under the equity method of accounting include the minority interest holders' portion of accumulated depreciation.

(6)

Exhibit 12

SIMON PROPERTY GROUP, L.P.
Computation of Ratio of Earnings to Fixed Charges
(in thousands)

            For purposes of calculating the ratio of earnings to fixed charges, "earnings" have been computed by adding fixed charges, excluding capitalized interest, to income from continuing operations including income from minority interests and our share of income from 50%-owned affiliates which have fixed charges, and including our share of distributed operating income from less than 50%-owned affiliates instead of our share of income from the less than 50%-owned affiliates. There are generally no restrictions on our ability to receive distributions from our unconsolidated joint ventures where no preference in favor of the other owners of the joint venture exists. "Fixed charges" consist of interest costs, whether expensed or capitalized, the interest component of rental expenses, losses on extinguishment of debt, and amortization of debt issuance costs.
