Beginning in 2022, 20% of the Company's annual incentive bonus will be tied to specific sustainability targets aligned with our sustainability goals. ELECTION OF BOARD OF DIRECTORS 20 PROXY STATEMENT 2022 | Annual Meeting of Shareholders Kim Ann Mink, Ph.D. The opportunities related to adjusted operating income were based two-thirds (40%) on business unit-specific results and one-third (20%) on consolidated Avient adjusted operating income results.

Every Avient associate is accountable for these objectives, which is why we have aligned 20% of our 2022 annual incentive plan with ESG metrics (see details on page 5). For 2022 we have added ESG performance metrics, which now account for 20% of our associates’ Annual Incentive Plan. Leek, United Kingdom 20.
