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.

Melt processing of SmartHeat RHC products is carried out at typical PET processing conditions at recommended dose rates, which range from .02% to .075%. Care must be taken to optimize the bottle blowing process due to the increased heat-up rate of the preform, to take advantage of the many benefits offered by this product range.
