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 Chief Operating Decision Maker (“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 organization provides general and administrative services, as well as support services, to each of our four operating segments. Management allocates certain shared costs between segments for selling, general and administrative expenses.

Segment information for the three and six months ended March 31, 2022 and 2021 is as follows:
