A zero recordable injury goal reflects Avient’s focus on the People aspect of our 4P sustainability cornerstones. OnColor™ IR Sortable Black Colorants include detectable colorants to allow reclaimed dark plastics, such as those found in food trays, to be detected and properly recycled by automated sorters. With each customer success story, there is a potential case study that allows us to step back, self-reflect, learn and get better.

The following discussion contains forward-looking statements that reflect our plans, estimates and beliefs. Historical information has been retrospectively adjusted to reflect the classification of discontinued operations. Additionally, we incurred $10.1 million of costs related to committed financing which are reflected in Interest expense, net.

In certain cases throughout this presentation, we have presented GAAP and non-GAAP financial measures adjusted to reflect full- year 2012 Pro forma results, including Spartech and Glasforms and excluding discontinued operations. • PolyOne’s chief operating decision makers use these financial measures to monitor and evaluate the ongoing performance of the Company and each business segment and to allocate resources.
