Senior management believes the measures described above 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.

Because their natural color is usually cream, white, beige or translucent, TPEs are very easy to color. Repurposing and recycling You can also make TPEs out of biopolymers, which are natural polymers produced by the cells of living organisms. For example, other plastics made out of natural resources such as sugar cane can be repurposed into TPEs to create new products.
