Forward-looking statements give current expectations or forecasts of future events and are not guarantees of future performance. They use words such as “will,” “anticipate,” “estimate,” “expect,” “project,” “intend,” “plan,” “believe,” and other words and terms of similar meaning in connection with any discussion of future operating or financial performance and/or sales.  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, retain relationships with customers of acquired companies, and achieve the expected results of such acquisitions, including whether such businesses will be accretive to our earnings;  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.  The above list of factors is not exhaustive.  We undertake no obligation to publicly update forward-looking statements, whether as a result of new information, future events or otherwise. Senior management uses operating income excluding special items, adjusted EPS and working capital 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.

Good surface aesthetics and color retention are maintained after sterilization processes.  The gloss level cannot be improved through process modification and only small improvements can be made with a change in the tooling surface. Similar to other resin systems, the addition of a color pigment may lower mechanical properties.
