Our measure of profit/loss for segment reporting purposes is Adjusted Operating EBITDA as this is the manner in which our CODM assesses performance and allocates resources. We define Adjusted Operating EBITDA as earnings (i.e., “Income (loss) before income taxes") before interest, depreciation, amortization, non-operating pension / other post-employment benefits (“OPEB”) / charges, and foreign exchange gains / losses, indirect legacy costs, and adjusted for significant items.
