Segment Reporting [Abstract]

SEGMENT REPORTING

SEGMENT REPORTING

During the first quarter of 2013, the Company adjusted its operating segments to integrate the business activities of Safety-Kleen, acquired in December 2012, and to incorporate other changes made in 2013 to the manner in which the Company manages its business, makes operating decisions and assesses its performance. The Company's operations are now managed in five reportable segments: Technical Services, Oil Re-refining and Recycling, SK Environmental Services, Industrial and Field Services and Oil and Gas Field Services. The prior year segment information has been recast 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, provision for income taxes and pre-tax, non-cash acquisition accounting adjustments. Also excluded are loss on early extinguishment of debt, other income (expense) 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 of fair value based on similar transactions with outside customers. 

The operations not managed through the Company’s five reportable 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 five 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 five reportable segments. Corporate Items revenues for the six months ended June 30, 2013 includes a one-time, non-cash reduction of approximately $10.2 million due to the impact of acquisition accounting adjustments on Safety-Kleen's historical deferred revenue balance at December 28, 2012. The revenue amounts of the five reportable segments for the six months ended June 30, 2013 exclude such adjustments to maintain comparability with future operating results and reflect how the Company manages the business.

The following table reconciles third party revenues to direct revenues for the three and six months ended June 30, 2013 and 2012 (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. Intersegment revenues represent the sharing of third party revenues among the segments based on products and services provided by each segment as if the products and services were sold directly to the third party. The intersegment revenues are shown net. The negative intersegment revenues are due to more transfers out of customer revenues to other segments than transfers in of customer revenues from other segments.
