Pension and Postretirement Benefit Plans

We have a number of defined contribution and defined benefit, qualified and nonqualified, pension plans covering eligible employees. Other postretirement benefits (OPEB), including medical and life insurance, are provided for certain employees upon retirement.

The service cost components of net periodic pension and OPEB costs are included in cost of sales and selling, general and administrative expenses as part of compensation cost and are eligible for capitalization in inventory and other assets. The non-service components are reported in other expense, net and are not eligible for capitalization.

Pension expense for 2019 increased versus the same period in 2018 as a result of a lower assumed return on plan assets, partially offset by lower interest expense and amortization of the net actuarial loss in the U.S.

Plan termination — In October 2017, upon authorization by the Dana Board of Directors, we commenced the process of terminating one of our U.S. defined benefit pension plans. Ultimate plan termination is subject to prevailing market conditions and other considerations, including interest rates and annuity pricing. Settlement of the plan obligations is expected to occur in the first half of 2019. At December 31, 2018, this plan had benefit obligations of $938 and assets of $773. The benefit obligations have been valued at the amount expected to be required to settle the obligations, using assumptions regarding the portion of obligations expected to be settled through participant acceptance of lump sum payments or annuities and the cost to purchase those annuities. The unrecognized actuarial losses of the plan in AOCI totaled $370 at the end of 2018. If the settlement is effected as expected in 2019, the plan's deferred actuarial losses remaining in AOCI at that time will be recognized as expense.
