(1)In 2020, 2019 and 2018, net periodic benefit cost for U.S. pension plans was $58, $127, and $239, respectively. (2)In 2020, 2019 and 2018, net periodic benefit cost for other postretirement benefits reflects a reduction of $1, $11, and $10, respectively, related to the recognition of the federal subsidy awarded under Medicare Part D. (3)In 2020, settlements were related to U.K. actions including lump sum benefits and the purchase of group annuity contracts as well as U.S. lump sum benefit payments. In 2019 and 2018, settlements were due to workforce reductions and the payment of lump sum benefits. (See Note E) (4)In 2020, the curtailment was due to workforce reductions. In 2019 and 2018, curtailments were due to a reduction of future benefits, resulting in the recognition of favorable and unfavorable plan amendments. (5)Service cost was included within Cost of goods sold, Selling, general administrative, and other expenses, and Research and development expenses; curtailments and settlements were included in Restructuring and other charges; and all other cost components were recorded in Other expense (income), net in the Statement of Consolidated Operations.
Schedule of Weighted Average Assumptions Used to Determine Benefit Obligations and Net Periodic Benefit Cost | Assumptions Weighted average assumptions used to determine benefit obligations for pension and other postretirement benefit plans were as follows:
December 31, | 2020 |  | 2019
Discount rate | 2.40 | % |  | 3.00 | %
Cash balance plan interest crediting rate | 3.00 | % |  | 3.00 | %
Weighted average assumptions used to determine net periodic benefit cost for pension and other postretirement benefit plans were as follows:
| 2020 |  | 2019 |  | 2018
Discount rate to calculate service cost(1) | 3.30 | % |  | 4.30 | % |  | 3.60 | %
Discount rate to calculate interest cost(1) | 2.70 | % |  | 3.90 | % |  | 3.30 | %
Expected long-term rate of return on plan assets | 6.00 | % |  | 5.60 | % |  | 5.90 | %
Rate of compensation increase(2) | — | % |  | 3.50 | % |  | 3.50 | %
Cash balance plan interest crediting rate | 3.00 | % |  | 3.00 | % |  | 3.00 | %
(1)In all periods presented, the respective global discount rates were used to determine net periodic benefit cost for most pension plans for the full annual period. However, the discount rates for a limited number of plans were updated during 2020, 2019, and 2018 to reflect the remeasurement of these plans due to new union labor agreements, settlements, and/or curtailments. The updated discount rates used were not significantly different from the discount rates presented. (2)Benefit accruals for future compensation under the Company’s major salaried and non-bargained hourly defined benefit pension plans have ceased. The rate of compensation increase no longer impacts the determination of the benefit obligation.
Schedule of Assumed Health Care Cost Trend Rates | Assumed health care cost trend rates for U.S. other postretirement benefit plans were as follows:
| 2020 |  | 2019 |  | 2018
Health care cost trend rate assumed for next year | 5.50 | % |  | 5.50 | % |  | 5.50 | %
Rate to which the cost trend rate gradually declines | 4.50 |  |  | 4.50 |  |  | 4.50 |
Year that the rate reaches the rate at which it is assumed to remain | 2023 |  | 2023 |  | 2022
Schedule of Pension and Postretirement Plans Investment Policy and Weighted Average Asset Allocations | Howmet’s pension plans’ investment policy at December 31, 2020 by asset class, were as follows:
Asset class | Policy range(1) |  |  |
Equities | 20–55% |  |  |
Fixed income | 25–55% |  |  |
Other investments | 15–35% |  |  |
Total |  |  |  |
(1)Policy range is for U.S. plan assets only, as both the U.K. and Canadian asset investment allocations are controlled by a third-party trustee with input from Howmet.
