NOTE 21 -SEGMENTS AND GEOGRAPHIC REGIONS

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 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.

Historical Delrin® costs that were classified as discontinued operation in prior years included only direct operating expenses incurred by Delrin® prior to the November 1, 2023 divestiture. Indirect costs, such as those related to corporate and shared service functions previously allocated to the Delrin® Business, did not meet the criteria for discontinued operations and were reported within continuing operations in the respective prior years. A portion of these historical indirect costs included costs related to activities the Company is undertaking on behalf of Delrin®, and for which it is reimbursed (“Future Reimbursable Indirect Costs”). Future Reimbursable Indirect Costs are reported within continuing operations but are excluded from operating EBITDA as defined below. The remaining portion of these indirect costs are not subject to reimbursement (“Stranded Costs”). Stranded Costs are reported within continuing operations in Corporate & Other and are included within Operating EBITDA.
