6. 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 CODM reviews operating results for the purpose 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 each of our four operating segments. Management allocates certain shared costs among segments for selling, general and administrative expenses and depreciation expense.
