[1] We consolidated the results of CVR effective May 5, 2012.

[2] Our second quarter 2012 results were restated due to (i) a purchase price allocation adjustment of $23 million related to an inventory step-up made during the fourth quarter 2012 related to the CVR acquisition and the common control impact of Mr. Icahn's transfer of his interest in IEP Energy to us made in the third quarter of 2012 and (ii) an adjustment of $21 million for a derivative related to a certain investment held by the Holding Company.
