Senior management has referenced adjusted EPS excluding the impact of additional shares issued in February 2020. Accordingly, for purposes of comparability to the January 28, 2020 guidance, and prior year, management has referenced adjusted EPS excluding the impact of the additional shares issued in February. Senior management believes these measures are useful to investors because they allow for comparison to PolyOne's performance in prior periods without the effect of items that, by their nature, tend to obscure PolyOne's operating results due to the potential variability across periods based on timing, frequency and magnitude.
