Segment Reporting [Abstract] |
Segment Reporting | SEGMENT REPORTINGAs described in Note 1, our operations are assessed based on two reportable segments. The operations of our segments are managed separately, and each segment has unique technology, services and customer classes. We account for intersegment sales at prices that we generally establish by reference to similar transactions with unaffiliated customers. Reportable segments are measured based on operating income exclusive of general corporate expenses and gains (losses) on sales of corporate assets. 1.
