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.

A COMPARISON: THE ECONOMIC CASE FOR TPEs Although vulcanized rubbers are initially an economical choice, processing presents many drawbacks that can wipe out these cost benefits.

Each of such adjustments has not yet occurred, are out of the Company's control and/or cannot be reasonably predicted.
