Non-Cash Activities We incurred a $13,091 contingent obligation to E.ON for payments made above an agreed amount on CAKY's behalf in excess of the amount agreed to in the Big Rivers Agreement in 2010. See Note 6 Debt for additional information about the E.ON contingent obligation. Due to the curtailment of our Ravenswood operations in February 2009, we reclassified certain inventory items into other assets. As a result, there was an $18,023 non-cash change in the inventory due to this reclassification. In 2011, 2010 and 2009, we issued shares of common stock to certain key employees to satisfy performance share liabilities of $0, $1,050 and $694, respectively, as part of our performance share program.
