Pension Postretirement And Postemployment Defined Benefit Plans [Abstract]  
Pension and Other Postretirement Benefits Disclosure [Text Block]
PENSION, POSTRETIREMENT AND POSTEMPLOYMENT DEFINED BENEFIT PLANS

We have three noncontributory defined benefit pension plans that together cover selected employees. Benefits under the plans were generally based on salary and years of service. All benefits are frozen; however participants in one of the plans may receive additional benefits if they remain employed until retirement age, resulting in the continuing service costs. Our liability and related expense for benefits under the plans are recorded over the service period of active employees based upon annual actuarial calculations. Plan funding strategies are influenced by government regulations and income tax laws. Plan assets consist primarily of domestic and foreign corporate equity securities, government and corporate bonds, hedge fund investments and cash.
 
In addition, we provide retiree medical and life insurance benefits under postretirement plans at several of our operating locations. The level and adjustment of participant contributions vary depending on the specific plan. PD LLC also provides postemployment disability benefits to certain employee groups prior to retirement. Our liability and related expense for benefits under the postretirement plans are recorded over the service period of active employees based upon annual actuarial calculations. We accrue postemployment disability benefits when it becomes probable that such benefits will be paid and when sufficient information exists to make reasonable estimates of the amounts to be paid. Plan assets may also be used to fund current medical costs of certain active employees.
 
We use a fiscal year end measurement date for all of our pension and postretirement medical plan obligations.
 
The net periodic cost (benefit) components of our pension and postretirement medical plans are as follows:
