Segment Information

SEGMENT INFORMATION

Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the chief operating decision maker, or decision making group, in deciding how to allocate resources and in assessing performance. Our chief operating decision maker is our Chief Executive Officer.

We currently report our segments based on a group structure organization. Our segments areIndustry Group and Science Group.

Market segment disclosures are presented to the gross profit level as this is the primary performance measure for which the segment general managers are responsible. Selling, general and administrative, research and development and other operating expenses are managed and reported at the corporate level and, because these costs are not directly tied to any individual market segment, they have not been allocated to the market segments. See the consolidated statements of operations for reconciliations from gross profit to income before income taxes. These reconciling items are not included in the measure of profit and loss for each reportable segment.
