Retirement Benefits [Abstract] |
|
Schedule of Defined Benefit Plans Disclosures |
The Pension and Postretirement Plans table summarizes the changes in the fair value of plan assets, changes in the projected benefit obligation (PBO), the funded status of both the accumulated benefit obligation (ABO) and the PBO, and the weighted-average assumptions used to determine benefit obligations for the pension plans and postretirement plans at December 31, 2017 and 2016. The estimate of the Corporation’s PBO associated with these plans considers various actuarial assumptions, including assumptions for mortality rates and discount rates. The discount rate assumptions are derived from a cash flow matching technique that utilizes rates that are based on Aa-rated corporate bonds with cash flows that match estimated benefit payments of each of the plans. The decreases in the weighted-average discount rate in 2017 and 2016 resulted in increases to the PBO of approximately $1.1 billion and $1.3 billion at December 31, 2017 and 2016.
