Segment Reporting Disclosure [Text Block]	20. ​ We derive our revenues, earnings and cash flows from the manufacture and sale of a wide variety of differentiated and commodity chemical products. We have four operating segments, which are also our reportable segments: Polyurethanes, Performance Products, Advanced Materials and Textile Effects. We have organized our business and derived our operating segments around differences in product lines. The major products of each reportable operating segment are as follows: ​ Segment Products Polyurethanes ​ MDI, polyols, TPU and other polyurethane-related products Performance Products ​ Specialty amines, ethyleneamines, maleic anhydride and technology licenses Advanced Materials ​ Specialty resin compounds; cross-linking, matting, and curing and toughening agents; epoxy, acrylic and polyurethane-based formulations; specialty nitrile latex, alkyd resins and carbon nano materials Textile Effects ​ Textile chemicals and dyes Sales between segments are generally recognized at external market prices and are eliminated in consolidation. We use adjusted EBITDA to measure the financial performance of our global business units and for reporting the results of our operating segments. This measure includes all operating items relating to the businesses. The adjusted EBITDA of operating segments excludes items that principally apply to our Company as a whole. The following schedule includes revenues and adjusted EBITDA for each of our reportable operating segments (dollars in millions). We have revised our prior years’ presentation below to reconcile total reportable segments’ adjusted EBITDA to income from continuing operations before income taxes, in addition to net income, and removed “corporate and other costs, net” from the total reportable segments’ adjusted EBITDA and included such amounts in the reconciliation to income from continuing operations before income taxes. Additionally, we have revised our prior years’ presentation of total reportable segments’ revenues, in which we removed intersegment eliminations from the total reportable segment’s revenues.
