Adjusted earnings per share increased to an all-time high of $0.46, up from $0.44 in the first quarter of 2014.  Factors that could cause actual results to differ materially from those implied by these forward-looking statements include, but are not limited to: our ability to realize anticipated savings and operational benefits from the realignment of assets, including the closure of manufacturing facilities; the timing of closings and shifts of production to new facilities related to asset realignments and any unforeseen loss of customers and/or disruptions of service or quality caused by such closings and/or production shifts; separation and severance amounts that differ from original estimates; amounts for non-cash charges related to asset write-offs and accelerated depreciation realignments of property, plant and equipment, that differ from original estimates; our ability to identify and evaluate acquisition targets and consummate acquisitions; the ability to successfully integrate acquired companies into our operations, retain the management teams of acquired companies and retain relationships with customers of acquired companies including, without limitation, Spartech Corporation and/or Accella Performance Materials; disruptions, uncertainty or volatility in the credit markets that could adversely impact the availability of credit already arranged and the availability and cost of credit in the future; the financial condition of our customers, including the ability of customers (especially those that may be highly leveraged and those with inadequate liquidity) to maintain their credit availability; the speed and extent of an economic recovery, including the recovery of the housing market; our ability to achieve new business gains; the effect on foreign operations of currency fluctuations, tariffs and other political, economic and regulatory risks; changes in polymer consumption growth rates and laws and regulations regarding the disposal of plastic in jurisdictions where we conduct business; changes in global industry capacity or in the rate at which anticipated changes in industry capacity come online; fluctuations in raw material prices, quality and supply and in energy prices and supply; production outages or material costs associated with scheduled or unscheduled maintenance programs; unanticipated developments that could occur with respect to contingencies such as litigation and environmental matters; an inability to achieve or delays in achieving or achievement of less than the anticipated financial benefit from initiatives related to working capital reductions, cost reductions and employee productivity goals; an inability to raise or sustain prices for products or services; an inability to maintain appropriate relations with unions and employees; our ability to continue to pay cash dividends; the amount and timing of repurchases of our common shares, if any; and other factors affecting our business beyond our control, including, without limitation, changes in the general economy, changes in interest rates and changes in the rate of inflation.

We  conduct  business  in  a  manner  intended  to  avoid   intentionally  or  knowingly  contributing  to  such  abuses.     As  stated  in  our  Code  of  Conduct,  “we strive to create a world-class sustainable organization, by conducting business in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs. This  includes  annually  conducting  a  reasonable  due  diligence  inquiry  of  our   suppliers  into  the  source  and  conflict  status  of  any  3TG  metals  contained  in  Avient  products  that  are  within  the   scope  of  the  Act.    

The data provided is for sites in High and Extremely High stress areas [Fixed row] (9.2.7) Provide total water withdrawal data by source. This is valuable information that can help to influence our initiatives and encourage continuous monitoring in areas of high and extremely high stress. Nevertheless, we still make a conscious effort to monitor our water consumption, conduct annual reviews of sites in high water risk areas and assign our manufacturing sites with the task to create and execute a water or waste reduction project annually.

Plastics Recyclers Europe (PRE) is an organization representing the voice of the European plastics recyclers who reprocess plastic waste into high-quality material destined for the production of new articles.
