Schedule of Segment Information

•Segment Net sales comprise sales to unaffiliated customers - inter-segment and inter-area sales are not significant and are eliminated in consolidation.

•Segment operating income consists of Net sales less operating expenses, including total corporate expenses, which are generally allocated to each segment on the basis of the segment's percentage of consolidated Net sales.
