SEGMENT INFORMATION
18. SEGMENT INFORMATION

Atkore operates its business through two operating segments which are also its reportable segments: Electrical and Safety & Infrastructure. The Company’s operating segments are organized based on primary market channel and, in most instances, the end use of products. The Company reviews the results of its operating segments separately for the purpose of making decisions about resource allocation and performance assessment. The Company evaluates performance on the basis of net sales and Adjusted EBITDA.

The Electrical segment manufactures high quality products used in the construction of electrical power systems including conduit, cable and installation accessories. This segment serves contractors in partnership with the electrical wholesale channel.

The Safety & Infrastructure segment designs and manufactures solutions including metal framing, mechanical pipe, perimeter security and cable management for the protection and reliability of critical infrastructure. These solutions are marketed to contractors, original equipment manufacturers and end users.
The Company’s Chief Operating Decision Maker (“CODM”) is the President and Chief Executive Officer. The CODM uses Adjusted EBITDA to allocate resources predominantly in the annual planning process. Adjusted EBITDA is used to monitor and evaluate periodic results against budget, forecast and prior period results.

Both segments use Adjusted EBITDA as the primary measure of profit and loss. Segment Adjusted EBITDA is income (loss) before income taxes, adjusted to exclude unallocated expenses, depreciation and amortization, interest expense, net, stock-based compensation, loss on extinguishment of debt, gains and losses on the divestiture of a business, asset impairment charges, certain legal matters, and other items, such as inventory reserves and adjustments, (gain) loss on disposal of property, plant and equipment, insurance recovery related to damages of property, plant and equipment, release of indemnified uncertain tax positions, realized or unrealized gain (loss) on foreign currency impacts of intercompany loans and related forward currency derivatives, gain on purchase of business, loss on assets held for sale, restructuring costs and transaction costs.

Intersegment transactions primarily consist of product sales at designated transfer prices on an arm’s-length basis. Gross profit earned and reported within the segment is eliminated in the Company’s consolidated results. Certain manufacturing and distribution expenses are allocated between the segments on a pro rata basis due to the shared nature of activities. Recorded amounts represent a proportional amount of the quantity of product produced for each segment. Certain assets, such as machinery and equipment and facilities, are not allocated to each segment despite serving both segments. These shared assets are reported within the Safety & Infrastructure segment. The Company allocates certain corporate operating expenses that directly benefit our operating segments, such as insurance and information technology, on a basis that reasonably approximates an estimate of the use of these services.
