Segment Information
 Due to the April 3, 2017 acquisition of Tealstone, the Company reviewed its reportable segments, operating segments and reporting units. Based on Sterling's review, the Company concluded that their operations consist of two reportable segments, two operating segments and two reporting unit components: heavy civil construction and residential construction.
Segment reporting is aligned based upon the services offered by two operating groups, which represent the following reportable segments: heavy civil construction and residential construction. Sterling's Chief Operating Decision Maker (“CODM”) evaluates the performance of the aforementioned operating groups based upon revenue and income from operations. Each operating group’s income from operations reflects corporate costs, allocated based primarily upon revenue.
The following table presents total revenue and income from operations by reportable segment for the three and nine months ended September 30, 2018 and 2017 (in thousands):
