10. Segment Information

MYR Group is a holding company with subsidiaries that are specialty electrical contractors that serve the United States and Canadian electrical infrastructure markets. The Company has two reporting segments, each a separate operating segment, which are referred to as T&D and C&I. Performance measurement and resource allocation for the reporting segments are based on many factors. The primary financial measures used to evaluate the segment information are contract revenues and income from operations, excluding general corporate expenses. General corporate expenses include corporate facility and staffing costs, safety costs, professional fees and management fees. The accounting policies of the segments are the same as those described in the Summary of Significant Accounting Policies in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016.

Transmission and Distribution: The T&D segment provides a broad range of services on electric transmission and distribution networks and on substation facilities which include design, engineering, procurement, construction, upgrade, maintenance and repair services with a particular focus on construction, maintenance and repair. T&D services include the construction and maintenance of high voltage transmission lines, substations and lower voltage underground and overhead distribution systems. The T&D segment also provides emergency restoration services in response to hurricane, ice or other storm-related damage. T&D customers include investor-owned utilities, cooperatives, private developers, government-funded utilities, independent power producers, independent transmission companies, industrial facility owners and other contractors throughout the United States and parts of Canada.

Commercial and Industrial: The C&I segment provides services such as the design, installation, maintenance and repair of commercial and industrial wiring, installation of traffic networks and the installation of bridge, roadway and tunnel lighting. Typical C&I contracts cover electrical contracting services for airports, hospitals, data centers, hotels, stadiums, convention centers, manufacturing plants, processing facilities, waste-water treatment facilities, mining facilities and transportation control and management systems. C&I segment services are generally performed in the western and northeastern United States and in western Canada. The C&I segment generally provides electric construction and maintenance services as a subcontractor to general contractors in the C&I industry, but also contracts directly with facility owners. The C&I segment has a diverse customer base with many long-standing relationships.
