[1] | For discussion of the settlement payments and settlement losses, see Components of net periodic benefit cost below. | |
[2] | Prior service costs are amortized on a straight-line basis over the average remaining service period of employees expected to receive benefits. | |
[3] | 2015 and 2014 exclude net unsettled trades (payable) receivable of $(20) million and $3 million, respectively. | |
[4] | Settlement losses result when benefit payments exceed the sum of the service cost and interest cost within a plan during the year. During 2013 the Company allowed certain former employees with deferred vested balances an opportunity to voluntarily elect an early payout of their pension benefits. The majority of these payouts were funded from existing pension plan assets. | |
