Segment Reporting [Abstract] |
Segment Reporting Disclosure [Text Block] | 16. Reportable Segments Our reportable segments are as follows:
· | Display Technologies – manufactures glass substrates primarily for flat panel liquid crystal displays.
· | Optical Communications – manufactures carrier network and enterprise network components for the telecommunications industry.
· | Environmental Technologies – manufactures ceramic substrates and filters for automotive and diesel applications.
· | Specialty Materials – manufactures products that provide more than 150 material formulations for glass, glass ceramics and fluoride crystals to meet demand for unique customer needs.
· | Life Sciences – manufactures glass and plastic labware, equipment, media and reagents to provide workflow solutions for scientific applications.
All other reportable segments that do not meet the quantitative threshold for separate reporting have been grouped as “All Other.” This group is primarily comprised of the results of Corning Precision Materials’ non-LCD business and new product lines and development projects that involve the use of various technologies for new products such as advanced flow reactors and adjacency businesses in pursuit of thin, strong glass. We prepared the financial results for our reportable segments on a basis that is consistent with the manner in which we internally disaggregate financial information to assist in making internal operating decisions. We included the earnings of equity affiliates that are closely associated with our reportable segments in the respective segment’s net income. We have allocated certain common expenses among reportable segments differently than we would for stand-alone financial information. Segment net income may not be consistent with measures used by other companies. The accounting policies of our reportable segments are the same as those applied in the consolidated financial statements. Reportable Segments (in millions)
