The Company sponsors noncontributory defined benefit (pension) plans covering most employees. The plans for salaried and hourly employees currently in effect are based on a formula using the participant’s years of service and compensation or using the participant’s years of service and a dollar amount. The plan is closed to new participants, and based on plan changes announced in 2006, pay for active plan participants was frozen as of December 31, 2007. Beginning in the first quarter of 2014, with the exception of plan participants at two of Tredegar's U.S. manufacturing facilities, the plan will no longer accrue benefits associated with crediting employees for service, thereby freezing future benefits under the plan.
