Litigation and other proceedings against us could be costly and time-consuming to defend, and due to the nature of our business and products, we may be liable for damages arising out of our acts or omissions, which may have a material adverse effect on us.

Labor disputes, labor shortages and increased turnover or increases in employee and employee-related costs could disrupt our operations, divert the attention of our management and may cause a decline in our production and a reduction in our profitability.

Our post-retirement obligations are currently underfunded. We may be required to make significant cash payments to our pension and other post-retirement plans, which will reduce the cash available for our business.
