NOTE 21 -SEGMENTS AND GEOGRAPHIC REGIONS

The Company's segments are aligned with the market verticals they serve, while maintaining integration and innovation strengths within strategic value chains. DuPont is comprised oftwo operating segments: ElectronicsCo and IndustrialsCo. Major products by segment include: ElectronicsCo (CMP pads and slurries, photoresists and advanced coatings for lithography, removers and cleaners; dielectric and metallization solutions for advanced chip packaging, specialty thermal materials and laminates); and IndustrialsCo (medical packaging, medical silicones, specialty medical devices, water purification and separation, water filtration and purification resins, flexible packaging products, nonwovens, aramids, construction materials, auto adhesives and fluids). The Company operates globally in substantially all of its product lines. Transfers of products between operating segments are generally valued at cost, to the extent such transfers are applicable.

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.
