(a) | In the second quarter of 2017, we settled the remaining obligation associated with the Hospira U.S. qualified defined benefit pension plan. We purchased a group annuity contract on behalf of the remaining plan participants with a third-party insurance provider. As a result, we were relieved of the $156 million net pension benefit obligation and recorded a pretax settlement gain of $41 million, partially offset by the recognition of actuarial losses and prior service costs upon plan settlement of approximately $30 million in Other (income)/deductions—net (see Note 3).
(b) | Effective January 1, 2018, we froze two significant defined benefit pension plans to future benefit accruals in the U.S. and U.K. and as a result, service costs for those plans are eliminated. In addition, due to the plan freeze, the average amortization period for the U.S. qualified plans and U.S. supplemental (non-qualified) plans was extended to the expected life expectancy of the plan participants, whereas the average amortization period in prior years utilized the expected future service period of plan participants.
(c) | We adopted a new accounting standard on January 1, 2018 that requires the net periodic pension and postretirement benefit costs other than service costs be presented in Other (income)/deductions––net on the consolidated statements of income. For additional information, see Note 1B and Note 4.
(d) | In 2017 and 2016, the changes to Other comprehensive (income)/loss for the international plans was impacted by foreign currency movements. For details of the changes in Other comprehensive (income)/loss, see the benefit plan activity in the consolidated statements of comprehensive income.
Schedule of Amounts in Accumulated Other Comprehensive Income/(Loss) Expected to be Amortized into 2014 Net Periodic Benefit Costs |
The following table provides the amounts in Accumulated other comprehensive loss expected to be amortized into 2019 net periodic benefit costs:
|  | Pension Plans |  |
(MILLIONS OF DOLLARS) |  | U.S. Qualified |  | U.S. Supplemental (Non-Qualified) |  | International |  | Postretirement Plans
Actuarial losses(a) |  | $ | (148 | ) |  | $ | (9 | ) |  | $ | (81 | ) |  | $ | (4 | )
Prior service credits and other |  | 3 |  |  | 1 |  |  | 3 |  |  | 178 |
Total |  | $ | (145 | ) |  | $ | (9 | ) |  | $ | (78 | ) |  | $ | 175 |
(a) | Due to the U.S. Pfizer Consolidated Pension Plan freeze effective for January 1, 2018, the average amortization period for the U.S. qualified plans and U.S. supplemental (non-qualified) plans reflect the expected life expectancy of the plan participants, whereas prior years utilized the expected future service period of plan participants. The average amortization periods to be utilized for 2019 are 24.2 years for our U.S. qualified plans, 25.3 years for our U.S. supplemental (non-qualified) plans, 20 years for our international plans, and 9.3 years for our postretirement plans.
Schedule of Assumptions Used |
The following table provides the weighted-average actuarial assumptions of our benefit plans:
(PERCENTAGES) |  | 2018 |  | 2017 |  | 2016
Weighted-average assumptions used to determine benefit obligations |  |  |  |  |  |
Discount rate: |  |  |  |  |  |
U.S. qualified pension plans |  | 4.4% |  | 3.8% |  | 4.3%
U.S. non-qualified pension plans |  | 4.3% |  | 3.7% |  | 4.2%
International pension plans |  | 2.5% |  | 2.3% |  | 2.4%
Postretirement plans |  | 4.3% |  | 3.7% |  | 4.2%
Rate of compensation increase: |  |  |  |  |  |
U.S. qualified pension plans(a) |  | — |  | 2.8% |  | 2.8%
U.S. non-qualified pension plans(a) |  | — |  | 2.8% |  | 2.8%
International pension plans |  | 1.4% |  | 2.5% |  | 2.6%
Weighted-average assumptions used to determine net periodic benefit cost |  |  |  |  |  |
Discount rate: |  |  |  |  |  |
U.S. qualified pension plans |  | 3.8% |  | 4.3% |  | 4.5%
U.S. non-qualified pension plans |  | 3.7% |  | 4.2% |  | 4.5%
International pension plans interest cost(b) |  | 2.0% |  | 2.1% |  | 2.7%
International pension plans service cost(b) |  | 2.3% |  | 2.3% |  | 3.0%
Postretirement plans |  | 3.7% |  | 4.2% |  | 4.5%
Expected return on plan assets: |  |  |  |  |  |
U.S. qualified pension plans |  | 7.5% |  | 8.0% |  | 8.0%

Postretirement plans |  | 7.5% |  | 8.0% |  | 8.0%
Rate of compensation increase: |  |  |  |  |  |
U.S. qualified pension plans |  | 2.8% |  | 2.8% |  | 2.8%
U.S. non-qualified pension plans |  | 2.8% |  | 2.8% |  | 2.8%
International pension plans |  | 2.5% |  | 2.6% |  | 2.6%
(a) | Effective January 1, 2018, we froze the defined benefit plans to future benefit accruals in the U.S. and members’ accrued benefits to that date no longer increase in line with future compensation increases. The rate of compensation increase is therefore no longer an assumption used to determine the benefit obligation.
(b) | Effective January 1, 2016, the Company changed the approach used to measure service cost and interest costs for certain international pension plans and other postretirement benefits. In accordance with this change, the effective rate for interest on the benefit obligations and effective rate for service cost, respectively, are reported for international pension plans.
Schedule of Health Care Cost Trend Rates |
The following table provides the healthcare cost trend rate assumptions for our U.S. postretirement benefit plans:

Healthcare cost trend rate assumed for next year (age 65 and older) |  | 6.5 | % |  | 7.0 | %
Rate to which the cost trend rate is assumed to decline |  | 4.5 | % |  | 4.5 | %

(a) | The favorable change in the funded status of our U.S. qualified plans was primarily due to an increase in the discount rate at the end of 2018, partially offset by a decrease in actual return on plan assets.
(b) | The favorable change in the international plans’ funded status was primarily due to favorable currency movements, partially offset by a decrease in the actual return on plan assets.
(c) | The favorable change in the funded status of our postretirement plans was primarily due to an increase in the discount rate at the end of 2018, partially offset by a decrease in actual return on plan assets.
(d) | For the U.S. and international pension plans, the benefit obligation is the PBO. For the postretirement plans, the benefit obligation is the ABO. The ABO for all of our U.S. qualified pension plans was $15.1 billion in 2018 and $16.7 billion in 2017. The ABO for our U.S. supplemental (non-qualified) pension plans was $1.3 billion in 2018 and $1.5 billion in 2017. The ABO for our international pension plans was $9.5 billion in 2018 and $10.1 billion in 2017.

(a) | The accumulated actuarial losses primarily represent the impact of changes in discount rates and other assumptions that result in cumulative changes in our PBO, as well as the cumulative difference between the expected return and actual return on plan assets. These accumulated actuarial losses are recognized in Accumulated other comprehensive loss and are amortized into net periodic benefit costs primarily over the average remaining service period for active participants for plans that are not frozen or the expected life expectancy of plan participants for frozen plans, using the corridor approach.
