The Company is one of the leading suppliers in these upstream energy applications and has long-standing customer relationships . The Chief Operating Decision Maker (CODM) evaluates the performance of the Companys reportable segments based on, among other measures, Segment Adjusted EBITDA. Management closely monitors the Segment Adjusted EBITDA of each reportable segment to evaluate past performance and actions required to improve profitability. Inter-segment sales and transfers are not significant. Administrative expenses related to the Companys corporate offices and shared service centers in the United States and Europe, which includes transaction processing, accounting and other business support functions, are allocated to the business segments. Certain administrative expenses, including senior management compensation, treasury, internal audit, tax compliance, certain information technology, and other corporate functions, are not allocated to the business segments.
