The Company sponsors noncontributory defined benefit (pension) plans covering certain current and former employees. The plan for salaried and hourly employees currently in effect is 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 was closed to new participants and pay for active plan participants for benefit calculations was frozen as of December 31, 2007. With the exception of plan participants at one of Tredegar’s U.S. manufacturing facilities, the plan no longer accrues benefits associated with crediting employees for service, thereby freezing future benefits under the plan.

Pension and other post-retirement liabilities were $90.0 million and $96.0 million at September 30, 2017 and December 31, 2016, respectively ($0.6 million included in “Accrued expenses” at September 30, 2017 and December 31, 2016, with the remainder included in “Other noncurrent liabilities” in the consolidated balance sheets). The Company’s required contributions are expected to be approximately $6 million in 2017. Contributions to the pension plan during the first nine months of 2017 were $4.4 million. Tredegar funds its other post-retirement benefits (life insurance and health benefits) on a claims-made basis, which the Company anticipates will be consistent with amounts paid for the year ended December 31, 2016, or $0.3 million.
