During the three months ended July 31, 2012, we paid terminated pension participants in certain of our defined benefit plans lump-sum cash settlements in order to reduce our future pension obligation and administrative costs. The charges related to the lump-sum cash settlements are included above in settlement loss and were reported in other special project costs in the Condensed Statement of Consolidated Income during the three months ended July 31, 2012.
