comparisons of adjusted net income attributable to PolyOne common shareholders, adjusted earnings per share (EPS) attributable to PolyOne common shareholders and 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 that current levels may serve as a base for future performance.
