9. SEGMENT AND GEOGRAPHICAL INFORMATION

Segment Information

During the three months ended March 30, 2018, the Company revised its segment reporting to conform to changes in its internal management reporting. As a result, beginning with the three months ended March 30, 2018, the Company’s two segments are Energy and Engineering and Consulting, and the Company’s chief operating decision maker, which continues to be its chief executive officer, receives and reviews financial information in this format. Accordingly, segment information has been revised for comparison purposes for all periods presented in the accompanying consolidated financial statements.

There were no intersegment sales in any of the three fiscal years ended December 27, 2019. The Company’s chief operating decision maker evaluates the performance of each segment based upon income or loss from operations before income taxes. Certain segment asset information including expenditures for long‑lived assets has not been presented as it is not reported to or reviewed by the chief operating decision maker. In addition, enterprise‑wide service line contract revenue is not included as it is impracticable to report this information for each group of similar services.

Financial information with respect to the reportable segments and reconciliation to the amounts reported in the Company’s consolidated financial statements follows:
