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.

This included an upgrade to the knife’s grips, which long had been made of metal. Although a very durable material, metal can present a challenge as it can become slippery when wet. They wanted to transition from metal to a polymer-based, two-component handle that would deliver: • scratch and chemical resistance • excellent mechanical properties • a grippy, soft-touch feel To support the transition, Victorinox sought our help based on its expertise in polymer science and ability to support product development and efficient manufacturing of the new two-component handles.

First, sheet metal restricts design flexibility, and different automotive OEMs request different attachment configurations for the part, so it becomes extremely time-consuming to design and fabricate multiple variations in metal. Design flexibility = fast customization: Plastic offers much greater design freedom than metal, enabling the company to quickly develop and produce variations of the seat securement part for different customers Injection molding = system cost savings: Compared to metal fabrication, which requires time-consuming secondary operations, injection molded plastics can be produced as a net-shape part in a single step, boosting productivity and lowering system costs.
