E. I. du Pont de Nemours and Company
Notes to the Consolidated Financial Statements (continued)
(Dollars in millions, except per share)
25. SEGMENT INFORMATION
The company consists of 13 businesses which are aggregated into seven reportable segments based on similar
economic characteristics, the nature of the products and production processes, end-use markets, channels of
distribution and regulatory environment. The company’s reportable segments are Agriculture & Nutrition, Electronics &
Communications, Performance Chemicals, Performance Coatings, Performance Materials, Safety & Protection, and
Pharmaceuticals. The company includes certain embryonic businesses not included in the reportable segments, such
as Applied BioSciences, and nonaligned businesses in Other.
Major products by segment include: Agriculture & Nutrition (hybrid seed corn and soybean seed, herbicides,
fungicides, insecticides, value enhanced grains and soy protein); Electronics & Communications (photopolymers and
electronic materials); Performance Chemicals (fluorochemicals, fluoropolymers, specialty and industrial chemicals,
and white pigments); Performance Coatings (automotive finishes, and industrial coatings); Performance Materials
(engineering polymers, packaging and industrial polymers, films and elastomers); Safety & Protection (nonwovens,
aramids and solid surfaces); and Pharmaceuticals (representing the company’s interest in the collaboration relating to
Cozaar/Hyzaarantihypertensive drugs, which is reported as other income). The company operates globally in
substantially all of its product lines.
In general, the accounting policies of the segments are the same as those described in the Summary of Significant
Accounting Policies. Exceptions are noted as follows and are shown in the reconciliations below. Segment sales
include transfers to another business segment. Products are transferred between segments on a basis intended to
reflect, as nearly as practicable, the market value of the products. Segment pre-tax operating income (loss) (PTOI) is
defined as operating income (loss) before income taxes, exchange gains (losses), corporate expenses and interest.
Segment net assets includes net working capital, net property, plant and equipment and other noncurrent operating
assets and liabilities of the segment. Affiliate net assets (pro rata share) excludes borrowing and other long-term
liabilities. Depreciation and amortization includes depreciation on research and development facilities and amortization
of other intangible assets, excluding write-down of assets which is discussed in Note 4.
