On a regular basis, the Company reviews its product line groupings to generate greater alignment within each product line.  Accordingly, in the third quarter of 2019,  the Company combined its Basic Minerals product line with its Household, Personal Care & Specialty Products product line, both within our Performance Materials segment. Prior year amounts were reclassified to conform to current presentation.
