11. OPERATING SEGMENTS

We manage and measure performance of our business in four distinct operating segments: Communications, Residential, Infrastructure Solutions and Commercial & Industrial. These segments are reflective of how the Company’s Chief Operating Decision Maker (“CODM”) reviews operating results for the purposes of allocating resources and assessing performance. The Company’s CODM is its Chief Executive Officer.

Transactions between segments, if any, are eliminated in consolidation. Our corporate office provides general and administrative services, as well as support services, to our four operating segments. Management allocates certain shared costs among segments for selling, general and administrative expenses and depreciation expense.
