11. OPERATING SEGMENTS

We manage and measure performance of our business in four distinct operating segments: Commercial & Industrial, Communications, Infrastructure Solutions and Residential. 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, as well as support services, to our four operating segments. Management allocates certain shared costs between segments for selling, general and administrative expenses and depreciation expense.

Segment information for the years ended September 30, 2019, 2018 and 2017 is as follows:
