Effect of one percentage point increase, description	The cap on the increase in employer’s cost was 2.5% per year. The assumed increase in total health care cost exceeded the 2.5% indexed cap, so increasing or decreasing the health care cost trend rate by 1% did not materially change our obligation or expense for the postretirement health care plan.
