(a)
Reflects a non-cash, out-of-year charge related to the adjustment of certain historical deferred vested liability balances in the Plan during the first quarter of 2017 recorded in Other pension (income) expense. See Note 5.

For the quarter and year to date ended June 30, 2017, we recognized additional loss due to pension settlements of $3 million and $8 million, respectively. Losses are a result of settlement transactions which exceeded the sum of annual service and interest costs for the applicable plan. These losses were recorded in Other pension (income) expense.
