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. Adjusted EPS attributable to PolyOne common shareholders is calculated as follows: 2009* 2010* 2011* 2012* 2013* 2014* 2015* 2016** 2017** 2018 2018*** Q1 2019*** 2019 Q1 2020 Net income from continuing operations attributable to PolyOne common shareholders $ 106.7 $ 152.5 $ 153.4 $ 53.3 $ 94.0 $ 78.0 $ 144.6 $ 166.4 $ 173.5 $ 161.1 $ 87.7 $ 22.4 $ 75.5 $ 33.1 Joint venture equity earnings, after tax (19.0) (14.7) (3.7) — — — — — — — — — — — Special items, before tax(1) (48.7) 24.2 (48.1) 55.1 46.3 164.2 87.6 23.8 32.9 59.5 58.7 12.2 61.7 9.6 Special items, tax adjustments(1) (27.2) (96.7) (24.7) (18.9) (13.7) (73.7) (58.7) (15.9) (24.8) (25.3) (25.1) (1.2) (5.9) (1.0) Adjusted net income from continuing operations attributable to PolyOne common shareholders $ 11.8 $ 65.3 $ 76.9 $ 89.5 $ 126.6 $ 168.5 $ 173.5 $ 174.3 $ 181.6 $ 195.3 $ 121.3 $ 33.4 $ 131.3 $ 41.7 Diluted shares 93.4 96.0 94.3 89.8 96.5 93.5 88.7 84.6 82.1 80.4 80.4 78.2 77.7 86.7 Adjusted EPS attributable to PolyOne common shareholders $ 0.13 $ 0.68 $ 0.82 $ 1.00 $ 1.31 $ 1.80 $ 1.96 $ 2.06 $ 2.21 $ 2.43 $ 1.51 $ 0.43 $ 1.69 $ 0.48 * Historical results are shown as presented in prior filings and have not been updated to reflect subsequent changes in accounting principle, discontinued operations or the related resegmentation. ** Pro forma for sale of Designed Structures and Solutions segment (DSS). *** Pro forma for sale of Performance Products and Solutions segment (PP&S).
