Company and Organization

Willbros Group, Inc., a Delaware corporation, and its subsidiaries (the “Company,” “Willbros” or “WGI”), is a specialty energy infrastructure contractor serving the oil and gas and power industries with offerings that primarily include construction, maintenance and facilities development services. The Company’s principal markets for continuing operations are the United States and Canada. The Company obtains its work through competitive bidding and through negotiations with prospective clients. Contract values range from several thousand dollars to several hundred million dollars, and contract durations range from a few weeks to more than two years.

The Company has three operating segments: Oil & Gas, Utility T&D and Canada. The Company's segments are comprised of strategic businesses that are defined by the industries or geographic regions they serve. Each is managed as an operation with well established strategic directions and performance requirements.

Management evaluates the performance of each operating segment based on operating income. To support the segments, the Company has a focused corporate operation led by the executive management team, which, in addition to oversight and leadership, provides general, administrative and financing functions for the organization. The costs to provide these services are allocated, as are certain other corporate costs, to the three operating segments.
