[1] Gain is a result of terminating future service benefits for all participants in one of our UK plans in 2013. The gain was recorded in YRI's G&A expenses, as amounts in Accumulated other comprehensive income (loss) related to this plan were in a net gain position.
[2] Special termination benefits primarily related to the U.S. business transformation measures taken in 2013, 2012 and 2011.
[3] For discussion of the settlement payments and settlement losses, see Pension Settlement Charges section of Note 4.
[4] 2013 includes the transfer of certain non-qualified pension benefits into a defined benefit plan not included in the table above due to its insignificance.
[5] Short-term investments in money market funds
[6] Securities held in common trusts
[7] Investments held directly by the Plan
[8] Includes securities held in common trusts and investments held directly by the Plan
[9] U. S. plans exclude net unsettled trades receivable of $3 million
[10] Prior service costs are amortized on a straight-line basis over the average remaining service period of employees expected to receive benefits.
[11] Settlement losses result from benefit payments exceeding the sum of the service cost and interest cost for each plan during the year. $10 million and $84 million for 2013 and 2012, respectively of these settlement losses, were not allocated for performance reporting purposes. See Note 4 for discussion of the settlement payments and settlement losses.
