Argotec acquisition) were down 2% constant currency, underperformed expectations • Chinese JVs EPS contribution was $0.16, underperformed expectations • Approximately $0.20 of non-recurring tax benefits in 2016 created negative comparison • Announced highly accretive ($0.30) and synergistic acquisition of Conwed
