Goodwill and Intangible Assets Disclosure [Abstract]

In first quarter 2016, as a result of the changes in Eastman's organizational and management structure, goodwill was reassigned to operating segments using a relative fair value allocation. In conjunction with the organizational changes, during first quarter 2016 Eastman performed an impairment assessment and concluded that no indication of an impairment existed. For further information on the organizational changes, see Note 1, "Significant Accounting Policies", and Note 20, "Segment Information".
