Segment Reporting [Abstract]

SEGMENT REPORTING

SEGMENT REPORTING

During the quarter ended March 31, 2011, the Company re-aligned its management reporting structure. Under the new structure, the Company’s operations are managed in four reportable segments: Technical Services, Field Services, Industrial Services and Oil and Gas Field Services. The new segment, Oil and Gas Field Services, consists of the previous Exploration Services segment, as well as certain oil and gas related field services departments that were re-assigned from the Industrial Services segment. In addition, certain departments from the Field Services segment were re-assigned to the Industrial Services segment.  Accordingly, the Company re-aligned and re-allocated departmental costs being allocated among the segments to support these management reporting changes.  The Company has recast the prior period segment information to conform to the current year presentation.

Performance of the segments is evaluated on several factors, of which the primary financial measure is "Adjusted EBITDA," which consists of net income plus accretion of environmental liabilities, depreciation and amortization, net interest expense, and provision for income taxes. Also excluded are other income and income from discontinued operations, net of tax as these amounts are not considered part of usual business operations. Transactions between the segments are accounted for at the Company's estimate based on similar transactions with outside customers.

The operations not managed through the Company's four operating segments are recorded as "Corporate Items." Corporate Items revenues consist of two different operations for which the revenues are insignificant. Corporate Items cost of revenues represents certain central services that are not allocated to the four operating segments for internal reporting purposes. Corporate Items selling, general and administrative expenses include typical corporate items such as legal, accounting and other items of a general corporate nature that are not allocated to the Company's four operating segments.

The following table reconciles third party revenues to direct revenues for the years ended December 31, 2011, 2010 and 2009 (in thousands). Third party revenue is revenue billed to outside customers by a particular segment. Direct revenue is the revenue allocated to the segment performing the provided service. The Company analyzes results of operations based on direct revenues because the Company believes that these revenues and related expenses best reflect the manner in which operations are managed.
