Patterson added, “We are an asset-light, high-touch business that generates very high free cash flow conversion. Pro Forma The Company acquired the Clariant Masterbatch business (“CMB”) on July 1, 2020 (the “Acquisition Date”). Management believes this provides better comparability of the performance of the combined businesses.

Avient acquired the Clariant Color business on July 1, 2020 (the “Acquisition Date”). It’s in this spirit that we joined legacy PolyOne and the Clariant Color business, two complementary businesses, and formed a new one that we’ve named Avient. These endeavors are made possible by the joining of our businesses.

Evaluate Resignations of Directors. • Review the continued appropriateness of Board membership of non-employee directors who significantly change their principal business or professional responsibility outside of the Company and submit a conditional letter of resignation to the Board and determine whether the resignation will be accepted. • Consider the resignation of an incumbent director who receives a greater number of votes “withheld” from his or her election than votes “for” his or her election in an election of directors that is not a contested election and recommend to the Board whether to accept or reject it, as provided in the Company’s Corporate Governance Guidelines. Recommendations as to the Board. • Make recommendations regarding the appropriate size of the Board and the effectiveness of the Board in fulfilling its obligations to the Company and its shareholders. • Evaluate and recommend the processes and practices that the Board shall use to conduct its business, including (a) the structure, charter and membership of committees of the Board and (b) committee membership qualifications, appointment and removal. Corporate Responsibility • Provide oversight and guidance with regard to how the Board and management evaluate and integrate corporate responsibility and sustainability matters into the Company’s business strategy and decision-making, including overseeing risks relating to the Company's programs, policies, and practices on sustainability and environmental, social, and governance matters, by receiving regular updates from management, as well as reviewing reports on corporate responsibility and/or sustainability published by the Company.
