The Company's measure of profit/loss for segment reporting purposes is Operating EBITDA as this is the manner in which the Company's chief operating decision maker ("CODM") assesses performance and allocates resources. The CODM utilizes Operating EBITDA to assess financial performance and allocate resources by comparing actual results to historical and previously forecasted results. The Company defines Operating EBITDA as earnings (i.e., “Income from continuing operations before income taxes") before interest, depreciation, amortization, non-operating pension / OPEB benefits / charges, and foreign exchange gains / losses, excluding future reimbursable indirect costs, and adjusted for significant items. Reconciliations of these measures are provided on the following pages.
