From the 10-Q:
Total pension expense, which consists of expense/(income) from our Primary Pension Plan and our supplemental pension plans, is based on our 2013 year-end measurement of pension plan assets and benefit obligations. For the first three months of 2014, we had income of $5 million related to our Primary Pension Plan compared to expense of $25 million in the prior year corresponding period. The change to income for our Primary Pension Plan is primarily a result of improved asset performance in prior periods, a higher base of plan assets and a 70 basis point increase in our discount rate.
Wonder what discount rate they are using these days?
Wonder how much of the improvement is tied to this?
