millions, except per share data) Senior management uses comparisons of adjusted net income from continuing operations attributable to PolyOne common shareholders, adjusted earnings per share (EPS) attributable to PolyOne common shareholders and adjusted earnings before interest, taxes, depreciation and amortization (EBITDA) to assess performance and allocate resources because senior management believes that these measures are useful in understanding current profitability levels and that current levels may serve as a base for future performance. Adjusted EPS attributable to PolyOne common shareholders is calculated as follows: 2009* 2010* 2011* 2012* 2013* 2014* 2015* 2016 2017 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 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 Special items, tax adjustments(1) (27.2) (96.7) (24.7) (18.9) (13.7) (73.7) (58.7) (15.9) (24.8) 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 Diluted shares 93.4 96.0 94.3 89.8 96.5 93.5 88.7 84.6 82.1 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 * 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

The resulting tensile test data shown in Figure 1 gives an indication of the variation in material response that can be observed as a function of the fibre orientations. In reality, the material response can fall anywhere between the curves shown in Figure 1.
