[1] During the fourth quarter of 2012 we identified errors of approximately $11 million which were primarily related to our discontinued Golf operations and the 2011 tax return filing process. The reversal of the out-of-period adjustment resulted in an $11 million increase in the loss from discontinued operations for the three months ended December 31, 2012. The recording of these items in the proper period resulted in an $11 million decrease in the loss from discontinued operations for the three months ended September 30, 2012.
