Organically, we utilized our proprietary innovation process to develop and launch new specialty and full-service solutions, including Versaflex™ HC, Excelite™ liquid foaming solutions, Percept™ Authentication Technologies, and InVisiOSM Color and Design Services, just to name a few. Performance Products & Solutions (PP&S) achieved a new record for return on sales at 7.2 percent and further reduced its working capital as a percent of sales to 4.3 percent. This strength was most notably evidenced by our hiring last year of Brad Richardson as CFO and Michael Garratt as president of PP&S.

These included headwinds from hydrocarbon based raw material deflation that reduced revenue by nearly $150 million and compressed margins, primarily within our PolyOne Distribution (POD) and Performance Products and Solutions (PP&S) segments. These associates led to an almost immediate impact in POD and PP&S, where sales cycles are often the shortest within the company. Our additive concentrates encompass a wide variety of performance and process enhancing characteristics and are commonly categorized by the function that they perform, including UV light stabilization and blocking, antimicrobial, anti-static, blowing or foaming, antioxidant, lubricant, oxygen and visible light blocking and productivity enhancement.
