INCREASED rPET CONTENT & IMPROVED QUALITY Reduced Preform Acetaldehyde Levels Acetaldehyde generation in the pre- form can lead to issues with taste and odor for bottle contents. They are metered into the PET stream just above the feed throat of the injection molding machine or extruder, using a Avient supplied ColorMatrix liquid metering system.

Tote containers (‘totes’) are commonly used as a cost-effective way to transport or store bulk products and materials. Many totes, or intermediate bulk containers (IBC), are made with rigid metal or polyethylene plastic caged within steel tubing. Avient’s CORE™ Vinyl Plastisols have been shipped in new collapsible totes for some time, and have been well received by customers.

millions, except per share data) Senior management uses comparisons of adjusted net income from continuing operations attributable to PolyOne common shareholders, adjusted earnings per share (EPS) attributable to PolyOne common shareholders and adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) to assess performance and allocate resources because senior management believes that these measures are useful in understanding current profitability levels and that current levels may serve as a base for future performance. Senior management believes these measures are useful to investors because they allow for comparison to PolyOne's performance in prior periods without the effect of items that, by their nature, tend to obscure PolyOne's operating results due to the potential variability across periods based on timing, frequency and magnitude.

Senior management believes these measures are useful to investors because they allow for comparison to Avient's performance in prior periods without the effect of items that, by their nature, tend to obscure Avient's operating results due to the potential variability across periods based on timing, frequency and magnitude. In addition, operating income before the effect of special items is a component of Avient's annual incentive plans and is used in debt covenant computations.
