Recent areas of focus for our M&A strategy have concentrated in our Engineered Materials and Global Color, Additives and Inks segments, including the creation of PolyOne Advanced Composites through the acquisition of five leading composite businesses. And combined efforts to execute our strategy have worked. 2018 marked the ninth consecutive year of adjusted EPS expansion at PolyOne, as we delivered $2.43 per share.
