Postemployment Benefit Plans

9 Months Ended

Note 10—Postemployment Benefit Plans

We maintain certain funded and unfunded defined benefit plans in the U.S., under which benefits have ceased accruing (collectively, the “U.S. Plans”). During the nine months ended September 30, 2016, we permitted certain participants of one of our funded U.S. Plans to elect to receive a payment of retirement benefits in the form of either (a) a lump sum distribution or (b) an annuity starting October 1, 2016.

We also maintain defined benefit plans in the United Kingdom, Norway, Nigeria and Indonesia (collectively, the “Non‑U.S. Plans”). During the nine months ended September 30, 2016, benefits ceased accruing under the defined benefit plan in the United Kingdom and certain defined benefit plans in Norway. Additionally, we maintain certain unfunded other postretirement employee benefit plans (collectively, the “OPEB Plans”), under which benefits to eligible participants diminish during a phase‑out period ending December 31, 2025.

The components of net periodic benefit costs, before tax, and funding contributions for these plans were as follows (in millions):
