[1] During the second quarter of 2012, the reclassification adjustment for the Simon Property Group, L.P. (SPG) units of $270 million was calculated by using the closing fair market value per SPG unit of $158.13 on July 19, 2012 for the two million REIT units that were redeemed on July 20, 2012. The REIT units were redeemed at a price of $124.00 per unit (see Note 17).
