Pensions Other Post Employment Benefits and Employee Benefit Plans [Abstract] |
Pension and Other Postretirement Benefits Disclosure [Text Block] | Pension, Other Post-employment Benefits and Employee Benefit Plans. Federal-Mogul, ARI and Viskase each sponsor several defined benefit pension plans (the ''Pension Benefits'') (and, in the case of Viskase, its pension plans include defined contribution plans). Additionally, Federal-Mogul, ARI and Viskase each sponsors health care and life insurance benefits (''Other Post-Employment Benefits'' or "OPEB") for certain employees and retirees around the world. The Pension Benefits are funded based on the funding requirements of federal and international laws and regulations, as applicable, in advance of benefit payments and the Other Benefits as benefits are provided to participating employees. As prescribed by applicable U.S. GAAP, Federal-Mogul, ARI and Viskase each uses, as applicable, appropriate actuarial methods and assumptions in accounting for its defined benefit pension plans, non-pension post-employment benefits, and disability, early retirement and other post-employment benefits. The measurement date for all defined benefit plans is December 31 of each fiscal year. Components of net periodic benefit cost (credit) for our Automotive, Railcar and Food Packaging segments for the three months ended March 31, 2012 and 2011 are as follows:
