Item 2.02.    Results of Operation and Financial Condition

        On October 29, 2007, Simon Property Group, Inc. (the "Registrant") issued a press release containing information on earnings for the quarter ended September 30, 2007 and other matters. A copy of the press release is attached hereto as Exhibit 99.2 and the information in the press release is incorporated by reference into this report.

        The press release and Supplemental Information package attached as Exhibit 99.1 use the non-GAAP financial measure of Funds from Operations ("FFO"). The Supplemental Information package also uses the non-GAAP measure of Net Operating Income ("NOI"). The Registrant considers FFO and NOI key measures of its operating performance that are not specifically defined by accounting principles generally accepted in the United States ("GAAP"). The Registrant believes that FFO and NOI are helpful to investors because they are widely recognized measures of the performance of real estate investment trusts and provide relevant bases for comparison among REITs. The Registrant also uses FFO and NOI internally to measure the operating performance of its portfolio. Reconciliations of net income to FFO on an estimated and historical basis are provided on pages 66 and 75 furnished herewith in Exhibit 99.2. Reconciliations of net income to NOI on a historical basis are provided on page 14 furnished herewith in Exhibit 99.1.

        The Registrant is furnishing the information contained herein, including Exhibit 99.2, pursuant to Item 2.02 of Form 8-K promulgated by the Securities and Exchange Commission (the "SEC"). This information shall not be deemed to be "filed" with the SEC or incorporated by reference into any other filing with the SEC.


Item 7.01.    Regulation FD Disclosure

        On October 29, 2007, the Registrant made available additional ownership and operational information concerning the Registrant, Simon Property Group, L.P., and properties owned or managed as of September 30, 2007 in the form of a Supplemental Information package, a copy of which is attached as Exhibit 99.1. The Supplemental Information package is also available upon request as specified therein.

        The Registrant is furnishing the information contained herein, including Exhibit 99.1, pursuant to Item 7.01 of Form 8-K promulgated by the SEC. This information shall not be deemed to be "filed" with the SEC or incorporated by reference into any other filing with the SEC.
