Senior management also uses operating income before special items to assess performance and allocate resources because senior management believes that these measures are useful in understanding current profitability levels and how it may serve as a basis for future performance. Management excludes intangible asset amortization from adjusted EPS as it believes excluding acquired intangible asset amortization is a useful measure of current period earnings per share. 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.
