Segment Information

Due to the April 3, 2017 acquisition of Tealstone, the Company has reviewed its reportable segments, operating segments and reporting units. Based on our review, we have concluded that our operations consist of two reportable segments, two operating segments and two reporting unit components: heavy civil construction and residential construction. In making this determination, the Company considered the discrete financial information used by our Chief Operating Decision Maker (“CODM”). Based on this approach, the Company noted that the CODM organizes, evaluates and manages the financial information of our aggregated heavy civil construction projects and the entire residential construction division separately when making operating decisions and assessing the Company’s overall performance. Furthermore, we considered the differences between the types of work performed in each reporting unit. Each heavy civil construction project has similar characteristics, includes similar services, has similar types of customers and is subject to similar economic and regulatory environments. Projects in our heavy civil construction segment typically last for several years, involve several subtasks and are accounted for using the percentage of completion method. Conversely, our residential construction projects typically consist of a high volume of independent units performed for customers that are billed, paid and accounted for as the individual units are completed. Each job performed in our residential construction segment typically takes less than one month to complete.

Segment reporting is aligned based upon the services offered by our two operating groups, which represent our reportable segments: heavy civil construction and residential construction, as mentioned above. Our 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. Prior to the acquisition of Tealstone, we only had one reportable segment, heavy civil construction. For more information about our 2016 results see Item 7.
