The following actuarial assumptions were used to calculate PBOP expense amounts:
PBOP
For the Years Ended December 31,
2014 2013 2012
Discount Rate 4.78 % - 5.10 % 4.04 % - 4.35 %4.58 % - 4.84 %
Expected Long-Term Rate of Return 8.25 % 8.25 % 7.30 % - 8.25 %
As of December 31, 2014 and 2013, the health care cost trend rate assumption used to determine the PBOP Plans'funded status was 6.5 percent and
7percent, respectively, subsequently decreasing to an ultimate rate of 4.5 percent in 2023. The health care cost trend rate assumption used to
calculate the PBOP expense amounts was 7 percent for the year ended December 31, 2014.
Assumed health care cost trend rates have a significant effect on the amounts reported for the health care plans. The effect of changing the assumed
health care cost trend rate by one percentage point for the year ended December 31, 2014 would have the following effects:
