USE OF NON-GAAP MEASURES PolyOne Corporation 3 This presentation includes the use of both GAAP (generally accepted accounting principles) and non-GAAP financial measures. The non-GAAP financial measures include: adjusted EPS, pro forma adjusted EPS, adjusted operating income, adjusted EBITDA, return on invested capital (ROIC) and free cash flow. A reconciliation of each historical non-GAAP financial measure with the most directly comparable GAAP financial measure is attached to this presentation, which is posted on our website at www.polyone.com.

L’avis porte sur la détectabilité et la triabilité de la solution colorante et non sur la recyclabilité de l’emballage au global. Les emballages non détectables lors de cette étape de tri sont orientés vers les refus des centres de tri pour une valorisation énergétique. La solution colorante noire CESA® IR PE 94000828 de Avient Corporation utilisée pour colorer des emballages rigides en PE est une alternative aux solutions colorantes non détectables.
