INDIANAPOLIS, Jan. 11 /PRNewswire-FirstCall/ -- Simon Property Group, Inc. (the "Company" or "Simon") (NYSE: SPG) today provided estimates of 2006 funds from operations ("FFO") per share and net income per share. The Company expects diluted FFO to be within a range of $5.20 to $5.32 per share for the year ending December 31, 2006, and diluted net income per share to be within a range of $1.71 to $1.83. The Company considers FFO a key measure of its operating performance that is not specifically defined by accounting principles generally accepted in the United States ("GAAP"). The Company believes that FFO is helpful to investors because it is a widely recognized measure of the performance of real estate investment trusts and provides a relevant basis for comparison of performance among REITs.

The Company's 2006 guidance is based upon its internal budgeting and planning process and management's view of current market conditions, including those in the retail real estate business. Assumptions for 2006 for the Company's U.S.-based assets include:

                                                        Premium     Community/
                                          Regional      Outlet(R)    Lifestyle
                                           Malls        Centers      Centers

     Occupancy at December 31, 2006  92.5 to 93.5%     98 to 99%     91 to 93%

     Releasing spread                    15 to 25%     15 to 25%      5 to 15%

     Comparable property NOI growth    2.5 to 3.5%   4.0 to 5.0%   2.0 to 3.0%

The 2006 guidance assumes timely completion of the Company's previously announced development activities; includes no future acquisition or disposition activities other than the impact in 2006 from 2005 activity; and contemplates stable retail and capital market environments.

The 2006 guidance also assumes an interest rate environment that is consistent with the current forward yield curves for one month LIBOR and the 10 Year U.S. Treasury note.

The following table provides the reconciliation of the range of estimated diluted net income per share to estimated diluted FFO per share.
