Pension expense for 2017 increased versus the same period in 2016 as a result of a lower assumed return on plan assets and an increase in amortization of the net actuarial loss in the U.S.

Plan termination — On October 25, 2017, the Dana Board of Directors authorized the company to pursue termination of one of its U.S. defined benefit pension plans. Ultimate plan termination is subject to prevailing market conditions and other considerations, including interest rates and annuity pricing. In the event the company proceeds with effectuating termination, subject to regulatory approval, settlement of the plan obligations is expected to occur in the first half of 2019. An increased liability to settle the plan obligations is expected based on participant settlement options and the cost to purchase annuities. Additionally, the deferred actuarial losses in accumulated other comprehensive income relating to the terminated plan will be recognized as expense. Based on the company's current assumptions, a pre-tax charge estimated in the range of $330 to $415 is expected at the time of settlement.
