The service cost component of net periodic postretirement benefit cost related to the employees of the operating segments are allocated to the operating segments based on their respective estimated census data.

Other Postretirement Benefits Plan Assumptions

Certain actuarial assumptions, such as discount rate, have a significant effect on the amounts reported for net periodic benefit cost and accrued benefit obligation amounts.

The discount rate is based on a hypothetical yield curve represented by a series of annualized individual zero-coupon bond spot rates for maturities ranging from one-half to thirty years.  The bonds used in the yield curve must have a rating of AA or better per Standard & Poor’s, be non-callable, and have at least $250 million par outstanding.  The yield curve is then applied to the projected benefit payments from the plan.  Based on these bonds and the projected benefit payment streams, the single rate that produces the same yield as the matching bond portfolio is used as the discount rate.

We review external data and our own internal trends for healthcare costs to determine the healthcare cost for the post retirement benefit obligation.  The assumed healthcare cost trend rates for pre-65 retirees were as follows:
 
December 31,

Rate that the cost trend rate gradually declines to
4.5

%
Year that the rate reaches the ultimate rate
2031

 
2024



For post-65 retirees, we provide a fixed dollar benefit, which is not subject to escalation.

We expect to make payments of approximately $4 million for each of the next five years under the provisions of our other postretirement benefit plans.
