Unless otherwise stated, Adjusted EBITDA figures included in this presentation exclude the impact of special items as defined in our quarterly earnings releases. In addition, operating income before the effect of special items is a component of Avient’s annual incentive plans and is used in debt covenant computations. We also monitor earnings (defined as net income from continuing operations) before interest, taxes, depreciation and amortization (EBITDA) and adjusted EBITDA (EBITDA before the impact of special items) as a supplement to our GAAP measures.
