In addition to packaging, we also work closely with customers to provide solutions for transportation, building and construction, healthcare and consumer markets. The remaining decline is a result of lower demand within the oil and gas and packaging end markets. In addition to packaging, we also work closely with customers to provide solutions for transportation, building and construction, healthcare and consumer markets.

We sell our solutions to Brand Owners/OEMs, processors and assemblers to enable their sustainability goals in applications like consumer, packaging, transportation, healthcare, defense, and building and construction. In alignment with our customers, we set a 2030 sustainability goal to enable 100% of our materials for the consumer packaging market to be recyclable, reusable, or compostable. We are continuously making a positive impact through our innovative portfolio of technologies that enable our customers to improve plastic recyclability and reduce the amount of material required for packaging.

Concurrently, there is rising market demand for plas- tic products treated with antimicrobial additives for applications in packaging, automotive, consumer goods, medical and healthcare, building and construction, sport- ing goods, and electronics markets. These various elastomers contain a propriety combina- tion of base resins, processing aids, fillers, stabilization packages, and other additives. They represent a wide variety of resins and/or resin mixtures, processing aids, and stabilization packages used in current TPE tech- nologies.

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.
