Segment Disclosures [Abstract]

Segment Disclosures

14.   Segment Disclosures

The Corporation has three reportable segments: Electrical, Steel Structures and HVAC. The Corporation’s reportable segments are based primarily on product lines and represent the primary mode used to assess allocation of resources and performance. The Corporation evaluates its business segments primarily on the basis of segment earnings, with segment earnings defined as earnings before corporate expense, depreciation and amortization expense, share-based compensation expense, interest, income taxes and certain other items. Corporate expense includes legal, finance and administrative costs. The Corporation has no material inter-segment sales.

The Electrical segment designs, manufactures and markets thousands of different electrical connectors, components and other products for industrial, construction and utility applications. The Steel Structures segment designs, manufactures and markets highly engineered steel transmission structures. The HVAC segment designs, manufactures and markets heating and ventilation products for commercial and industrial buildings. The Corporation’s U.S. Electrical and International Electrical operating segments have been aggregated in the Electrical reporting segment since they have similar economic characteristics as well as similar products and services, production processes, types of customers and methods used for distributing their products.
