The use of a hot sprue, which may be viewed as an extension of the machine nozzle, can sometimes reduce cycle time. Process Conditions for Hot Sprue Bushings or Extended Nozzles Hot sprue bushings should be viewed as an extension of the machine’s nozzle.

In the Compensation Committeeʼs view, this analysis demonstrated that the non-employee Directorsʼ compensation was below the median of our peer group. The Compensation Committee considered the voting results as well as other input from conversations held with investors and viewed them as continued support of our executive compensation programs. At that time, we viewed the targeted level of performance for each original measure as challenging to achieve.

These personal values begin with each of us—the judgments and decisions we make as individuals affect the way PolyOne is viewed in the marketplace and in the communities where we work. Product data associated with life cycle analysis will give a more holistic view of the trade-offs all products inherently have, as far as impact to human health and the environment. We view water intensity and management as an important consideration in many industrial sectors, though PolyOne’s operations are generally not water intensive.
