BUSINESS SEGMENTS

The Company has four reportable segments based on its management structure. Each segment is global in nature with a manager responsible for segment operational performance and the allocation of capital within the segment. Net corporate expense is net of certain service‑related expenses that are allocated to business units generally on the basis of employee headcounts.

Reportable segments are as follows:

ENGINEERED SUPPORT STRUCTURES: This segment consists of the manufacture of engineered metal and composite poles, towers, and components for global lighting, traffic, and wireless communication markets, engineered access systems, integrated structure solutions for smart cities, and highway safety products;

UTILITY SUPPORT STRUCTURES: This segment consists of the manufacture of engineered steel and concrete structures for the global utility transmission, distribution, and generation applications, renewable energy generation equipment, and inspection services;

COATINGS: This segment consists of galvanizing, painting, and anodizing services; and

IRRIGATION: This segment consists of the manufacture of agricultural irrigation equipment, parts, services, tubular products, water management solutions, and technology for precision agriculture.

In addition to these four reportable segments, the Company had other businesses and activities that individually are not more than 10% of consolidated sales, operating income or assets. This includes the manufacture of forged steel grinding media for the mining industry and is reported in the "Other" category.

The Company evaluates the performance of its business segments based upon operating income and invested capital. The Company does not allocate LIFO expense, interest expense, non-operating income and deductions, or income taxes to its business segments.
