Assumptions used to determine year-end pension and postretirement benefit obligations

Assumptions used to determine the year-end pension and postretirement benefit obligations are as follows:

	2012	2011
Pension
Weighted average discount rate	4.09%	4.96%
Mortality table	RP-2000/IRS Static Basis	RP-2000
Postretirement
Discount rate	4.17%	5.17%
Health care cost trend rate assumed for next year	7.00%	7.00%
Rate to which the cost trend rate is assumed to decline (ultimate trend rate)	5.00%	5.00%
Year that the rate reaches the ultimate trend	2020	2020
