11. Segment Information

Our activities are within the mechanical services industry and the electrical services industry, which represent our two reportable segments. We aggregate our operating segments into two reportable segments, as the operating segments meet all of the aggregation criteria. On January 1, 2021, we completed a change in the structure of our internal organization which resulted in a portion of our electrical segment’s business being moved to the mechanical segment. We reallocated goodwill between our reorganized reporting units and have restated comparative prior period information for the reorganized reportable segments in accordance with the guidance on segment reporting. Accordingly, we have restated comparative prior period information for the reorganized reportable segments in the tables below. The following table presents information about our reportable segments (in thousands):
