It is more difficult for a TPE to form a melt bond with a semi- crystalline polymer, such as polyamide, than with an amorphous polymer like polycarbonate. As an example, most TPEs do not bond effectively to heat stabilized grade polyamide 6 (HS). Other commercial TPEs do not perform well in comparison, to various polyamide types considered in this study.

The Board also participates in an ongoing effort to assess and analyze the most likely areas of future risk for the Company by asking our management team to discuss the most likely sources of material future risks and how we are addressing any significant potential vulnerability. We do not have employment agreements with our Named Executive Officers. Risk Assessment of the Compensation Programs As part of the Compensation Committee’s annual governance process, in October 2017 we conducted a formal assessment of our compensation programs to ensure that they do not create risks that are reasonably likely to have a material adverse effect on PolyOne.
