SIMON PROPERTY GROUP
Overview

The Company

Simon Property Group, Inc., ("Simon," "we," "us," "our," or the "Company") (NYSE:SPG) is a self-administered and self-managed real estate investment trust ("REIT"). Simon Property Group, L.P., or the Operating Partnership, is a majority-owned subsidiary partnership of the Company. Together, the Company and the Operating Partnership, or Simon Group, are engaged primarily in the ownership, development and management of retail real estate properties including regional malls, Premium Outlets®, The Mills®, community/lifestyle centers and international properties. At March 31, 2010, we owned or had an interest in 381 properties comprising 261 million square feet of gross leasable area in North America, Europe and Asia.

This package was prepared to provide (1) ownership information, (2) certain operational information, and (3) balance sheet information as of March 31, 2010, for the Company and the Operating Partnership.

Beginning with the first quarter of 2010, we modified the reporting of statistics for our U.S. businesses by combining the Company's regional malls and Premium Outlets. We made this change for several reasons including (1) it is more representative of Simon's enterprise performance, as combined, these portfolios represent over 86% of our net operating income, (2) the historically bright line between malls and outlets is becoming more blurred every day as many tenants are leasing space in both property types, and (3) we consolidated the back-of-house operations for our outlets into our Indianapolis infrastructure last year.

Certain statements made in this Supplemental Package 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 actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks, uncertainties and other factors. Such factors include, but are not limited to: our ability to meet debt service requirements, the availability and terms of financing, changes in our credit rating, changes in market rates of interest and foreign exchange rates for foreign currencies, changes in value of investments in foreign entities, the ability to hedge interest rate risk, risks associated with the acquisition, development, expansion, leasing and management of properties, general risks related to retail real estate, the liquidity of real estate investments, environmental liabilities, international, national, regional and local economic climates, changes in market rental rates, trends in the retail industry, relationships with anchor tenants, the inability to collect rent due to the bankruptcy or insolvency of tenants or otherwise, risks relating to joint venture properties, costs of common area maintenance, competitive market forces, risks related to international activities, insurance costs and coverage, terrorist activities, changes in economic and market conditions 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 annual and quarterly periodic reports filed with the SEC. We may update that discussion in our periodic reports, but otherwise we undertake no duty or obligation to update or revise these forward-looking statements, whether as a result of new information, future developments, or otherwise.

SIMON PROPERTY GROUP
Reconciliation of Net Income to NOI
As of March 31, 2010
(in thousands, except as noted)

Industry practice is to evaluate real estate properties on an unleveraged basis. Net Operating Income ("NOI") is a standard industry performance measure which is defined as operating income plus depreciation and amortization, both calculated in accordance with accounting principles generally accepted in the United States ("GAAP"). We consider NOI to be a key measure of our operating performance that is not specifically defined by GAAP. We believe that NOI is helpful to investors because it is a widely recognized measure of the performance of REITs and provides a relevant basis for comparison among REITs. We also use NOI internally to measure the operating performance of our portfolio.

However, you should understand that NOI:

•: does not represent cash flow from operations as defined by GAAP,
•: should not be considered as an alternative to net income determined in accordance with GAAP as a measure of operating performance,
•: is not an alternative to cash flows as a measure of liquidity, and
•: is not indicative of cash flows from operating, investing and financing activities.

The Reconciliation of Net Income to NOI provides net income, which we believe is the most directly comparable GAAP financial measure, and reconciles the amounts to "Total NOI of the Simon Group Portfolio." This schedule also provides the change in NOI of comparable properties for the three months ended March 31, 2010.
