Business Segment Information [Abstract]

BUSINESS SEGMENT INFORMATION

Note 4:          BUSINESS SEGMENT INFORMATION

As previously mentioned, we operate in five segments. We determine our operating segments based on the discrete financial information that is regularly evaluated by our chief operating decision maker, our President and Chief Executive Officer, in deciding how to allocate resources and in assessing performance. Intersegment sales are not material and are eliminated in the corporate segment. Our reportable measure of profit or loss for each segment is operating profit, which is defined as net sales less cost of sales and selling, general and administrative expenses related to a segment's operations. The costs deducted to arrive at operating profit do not include several items, such as net interest expense or income taxes. Segment assets are those assets used in the operations of that segment. Corporate assets include assets used in the operation of this segment as well as those used by or shared amongst our segments, including certain cash and equivalent assets, certain fixed assets, assets associated with certain employee benefit plans, and other miscellaneous assets.

The following tables set forth certain financial information by segment:
