Postretirement Medical Benefits [Member]

Schedule of Net Funded Status [Table Text Block]

The Company does not believe the U.S. Health Care Reform: The Patient Protection and Affordable Care Act and The Health Care and Education Reconciliation Act will have a significant impact on the Company's cost for postretirement medical benefits.

During 2014, the Company made changes to the postretirement medical benefits for non-union personnel and certain labor groups to sunset the postretirement medical benefits beginning in 2015. As a result of these changes, the Company recognized a partial curtailment gain of $25 million during December 31, 2014. The curtailment gain included $5 million associated with an embedded sick leave subsidy. This subsidy was used to establish a new compensated absence liability. The net impact of the curtailment gain of $20 million is included in special items in the income statement.
