Subsequent Events [Abstract]
Subsequent Events	SUBSEQUENT EVENTS Amended Retiree Benefit Plan In October 2011, we amended our retiree medical plan by, among other things, placing a cap (effective January 1, 2012) on our contributions for certain retiree groups. In connection with this plan amendment, we remeasured our postretirement obligation as of the plan amendment date. The plan amendment and remeasurement resulted in a decrease in the postretirement liability and an increase in other comprehensive income (before taxes) of approximately $20 million in October 2011.
