____________________

(1)

The healthcare cost trend rate reflects the estimated increase in gross medical claims costs. As a result of the plan amendment adopted effective October 1, 2002, our effective per person retiree medical cost increase is zero percent beginning in 2005 for the majority of our postretirement benefit plans. For our other plans, we assume the gross healthcare cost trend rate will decrease to 5.50% in 2017.


(2)	Decreasing to 4.50% in 2017.
