Operating Segments

Operating Segments

The Company manages its business under the following three operating segments:

Energy: The Energy operating segment provides services to a range of clients including energy companies, utilities, other commercial entities, and state and federal government entities. The Company's services include program management, engineer/procure/construct projects, design, and consulting. The Company's typical projects involve upgrades, design and new construction for electric transmission and distribution systems and substations; energy efficiency program design and management; and renewable energy development and power generation.

Environmental: The Environmental operating segment provides services to a wide range of clients including industrial, transportation, energy and natural resource companies, as well as federal, state and municipal agencies. The Environmental operating segment is organized to focus on key areas of demand including: environmental management of buildings and facilities; air quality measurements and modeling of potential air pollution impacts; water quality and water resource management; assessment and remediation of contaminated sites and buildings; hazardous waste management; construction monitoring, inspection and management; environmental, health and safety management and sustainability advisory services; compliance auditing and strategic due diligence; environmental licensing and permitting of a wide variety of projects; and natural and cultural resource assessment, protection and management.

Infrastructure: The Infrastructure operating segment provides services related to the expansion of infrastructure capacity, the rehabilitation of overburdened and deteriorating infrastructure systems, and the management of risks related to security of public and private facilities. The Company's client base is predominantly state and municipal governments as well as select commercial developers. In addition, the Company provides infrastructure services on projects originating in its Energy and Environmental operating segments. Primary services include: roadway, bridge and related surface transportation design; structural design and inspection of bridges; program management; construction engineering inspection and construction management for roads and bridges; civil engineering for municipalities and public works departments; geotechnical engineering services; and security assessments, design and construction management.

The Company's chief operating decision maker ("CODM") is its Chief Executive Officer ("CEO"). The Company's CEO manages the business by evaluating the financial results of the three operating segments focusing primarily on segment revenue and segment profit. The Company utilizes segment revenue and segment profit because it believes they provide useful information for effectively allocating resources among operating segments; evaluating the health of its operating segments based on metrics that management can actively influence; and gauging its investments and its ability to service, incur or pay down debt. Specifically, the Company's CEO evaluates segment revenue and segment profit and assesses the performance of each operating segment based on these measures, as well as, among other things, the prospects of each of the operating segments and how they fit into the Company's overall strategy. The Company's CEO then decides how resources should be allocated among its operating segments. The Company does not track its assets by operating segment, and consequently, it is not practical to show assets by operating segment. Segment profit includes all operating expenses except the following: costs associated with providing corporate shared services (including certain depreciation and amortization), goodwill and intangible asset write-offs, stock-based compensation expense and amortization of intangible assets. Depreciation expense is primarily allocated to operating segments based upon their respective use of total operating segment office space. Assets solely used by Corporate are not allocated to the operating segments. Inter-segment balances and transactions are not material. The accounting policies of the operating segments are the same as those for the Company as a whole, except as discussed herein.

The following tables present summarized financial information for the Company's operating segments (as of and for the periods noted below).
