Pension Benefit Plans and Other Postretirement Benefits |
Pension Benefit Plans and Other Postretirement Benefits | 9. Pension Benefit Plans and Other Postretirement Benefits Pension Benefit Plans The Company has defined benefit pension plans covering a substantial number of employees located in the United States and several other non-U.S. jurisdictions. Benefits generally are based on compensation for salaried employees and on length of service for hourly employees. The Company’s policy is to fund pension plans such that sufficient assets will be available to meet future benefit requirements. The Company’s defined benefit pension plans use a December 31 measurement date. The following tables relate to the Company’s principal defined benefit pension plans. The changes in the pension benefit obligations for the year are as follows:

The Company recognizes the funded status of each pension benefit plan on the balance sheet. The funded status of each plan is measured as the difference between the fair value of plan assets and actuarially calculated benefit obligations as of the balance sheet date. Actuarial gains and losses are accumulated in Other Comprehensive Income and the portion of each plan that exceeds 10% of the greater of that plan’s assets or projected benefit obligation is amortized to income on a straight-line basis over the average remaining service period of employees still accruing benefits or the expected life of participants not accruing benefits if all, or almost all, of the plan’s participants are no longer accruing benefits. The funded status of the pension plans at year end is as follows:
|  | U.S. |  | Non-U.S. |
|  | 2015 |  | 2014 |  | 2015 |  | 2014 |
Plan assets at fair value |  | $ | 1,909 |  | $ | 2,190 |  | $ | 1,012 |  | $ | 1,094 |

In 2014, the Company amended its salary pension plan in North America to freeze future pension benefits effective January 1, 2016. This action required an obligation remeasurement for the curtailment of benefits, which resulted in a reduction of the Company’s pension expense. Also in 2014, the Company settled a portion of the U.S. Salary Pension Plan pension obligation, which resulted in a settlement charge of $30 million and, in 2013, $8 million of special termination benefits were recorded in discontinued operations. On October 1, 2014, the Company settled the liability associated with its pension plan in the Netherlands, resulting in a settlement charge of approximately $35 million in the fourth quarter of 2014. Non-U.S. pension expense excludes $3 million and $6 million of pension settlement costs that were recorded in restructuring expense in 2014 and 2013, respectively. The table above excludes these charges. Amounts that are expected to be amortized from accumulated other comprehensive income into net pension expense during 2016:

The weighted average assumptions used to determine benefit obligations are as follows:
|  | U.S. |  | Non-U.S. |
|  | 2015 |  | 2014 |  | 2015 |  | 2014 |
Discount rate |  | 4.43 | % | 4.05 | % | 3.82 | % | 3.65 | %
Rate of compensation increase |  | 2.97 | % | 2.96 | % | 2.84 | % | 2.89 | %
The weighted average assumptions used to determine net periodic pension costs are as follows:
|  | U.S. |  | Non-U.S. |
|  | 2015 |  | 2014 |  | 2013 |  | 2015 |  | 2014 |  | 2013 |
Discount rate |  | 4.05 | % | 4.81 | % | 4.11 | % | 3.65 | % | 4.14 | % | 3.89 | %
Rate of compensation increase |  | 2.96 | % | 2.97 | % | 2.97 | % | 2.89 | % | 3.31 | % | 3.08 | %
Expected long-term rate of return on assets |  | 8.00 | % | 8.00 | % | 8.00 | % | 7.21 | % | 7.23 | % | 6.34 | %
Future benefits are assumed to increase in a manner consistent with past experience of the plans, which, to the extent benefits are based on compensation, includes assumed salary increases as presented above. For 2015, the Company’s weighted average expected long-term rate of return on assets was 8.0% for the U.S. plans and 7.21% for the non-U.S. plans. In developing this assumption, the Company evaluated input from its third party pension plan asset consultants, including their review of asset class return expectations and long-term inflation assumptions. The Company also considered its historical 10-year average return (through December 31, 2014), which was in line with the expected long-term rate of return assumption for 2015. It is the Company’s policy to invest pension plan assets in a diversified portfolio consisting of an array of asset classes within established target asset allocation ranges. The investment risk of the assets is limited by appropriate diversification both within and between asset classes. The assets for the U.S. plans are maintained in a group trust. The U.S. plans hold no individual assets other than the investment in the group trust. The assets of the group trust and the Company’s non-U.S. plans are primarily invested in a broad mix of domestic and international equities, domestic and international bonds, and real estate, subject to the target asset allocation ranges. The assets are managed with a view to ensuring that sufficient liquidity will be available to meet expected cash flow requirements. The investment valuation policy of the Company is to value investments at fair value. All investments are valued at their respective net asset values. Equity securities for which market quotations are readily available are valued at the last reported sales price on their principal exchange on valuation date or official close for certain markets. Fixed income investments are valued by an independent pricing service. Investments in registered investment companies or collective pooled funds are valued at their respective net asset values. Short-term investments are stated at amortized cost, which approximates fair value. The fair value of real estate is determined by periodic appraisals. The Company’s U.S. pension plan assets held in the group trust are classified as Level 2 assets in the fair value hierarchy. The total U.S. plan assets amounted to $1,909 million and $2,190 million as of December 31, 2015 and 2014, respectively. In 2015, the U.S. plan assets consisted of approximately 62% equity securities, 30% debt securities, and 8% real estate. The following table sets forth by level, within the fair value hierarchy, the Company’s non-U.S. pension plan assets at fair value as of December 31, 2015 and 2014:
|  | 2015 |  | 2014 |  | Target
|  | Level 1 |  | Level 2 |  | Level 3 |  | Level 1 |  | Level 2 |  | Level 3 |  | Allocation

Equity securities |  |  | 278 |  |  | 176 |  |  |  |  |  | 343 |  |  | 200 |  |  |  |  | 45 | - | 55 | %
Debt securities |  |  | 329 |  |  | 111 |  |  |  |  |  | 364 |  |  | 119 |  |  | 2 |  | 40 | - | 50 | %
Real estate |  |  |  |  |  | 53 |  |  | 5 |  |  |  |  |  | 30 |  |  | 3 |  | 0 | - | 10 | %
Other |  |  |  |  |  | 24 |  |  | 6 |  |  |  |  |  | 19 |  |  |  |  | 0 | - | 10 | %
Total assets at fair value |  | $ | 637 |  | $ | 364 |  | $ | 11 |  | $ | 721 |  | $ | 368 |  | $ | 5 |  |  |  |  |
The following is a reconciliation of the Company’s pension plan assets recorded at fair value using significant unobservable inputs (Level 3):
|  | 2015 |  | 2014 |
Beginning balance |  | $ | 5 |  | $ | 8 |
Net increase (decrease) |  |  | 6 |  |  | (3) |
Ending balance |  | $ | 11 |  | $ | 5 |
The net increase (decrease) in the fair value of the Company’s Level 3 pension plan assets is primarily due to purchases and sales of unlisted real estate funds. The change in the fair value of Level 3 pension plan assets due to actual return on those assets was immaterial in 2015. In order to maintain minimum funding requirements, the Company is required to make contributions to its defined benefit pension plans of $25 million in 2016. The following estimated future benefit payments, which reflect expected future service, as appropriate, are expected to be paid in the years indicated:
Year(s) |  | U.S. |  | Non-U.S.
2016 |  | $ | 171 |  | $ | 59
2017 |  |  | 175 |  |  | 55
2018 |  |  | 163 |  |  | 56
2019 |  |  | 162 |  |  | 58
2020 |  |  | 160 |  |  | 60
2021-2025 |  |  | 744 |  |  | 331
The Company also sponsors several defined contribution plans for all salaried and hourly U.S. employees, and employees in Canada, the U.K., The Netherlands and Australia. Participation is voluntary and participants’ contributions are based on their compensation. The Company matches contributions of participants, up to various limits, in substantially all plans. Company contributions to these plans amounted to $29 million in 2015, $19 million in 2014, and $16 million in 2013. Postretirement Benefits Other Than Pensions The Company provides retiree health care and life insurance benefits covering certain U.S. salaried and hourly employees, and substantially all employees in Canada. Benefits provided by the Company for hourly retirees are determined by collective bargaining. Employees are generally eligible for benefits upon retirement and completion of a specified number of years of creditable service. The Company uses a December 31 measurement date to measure its postretirement benefit obligations. The changes in the postretirement benefit obligations for the year are as follows:
|  | U.S. |  | Non-U.S. |
|  | 2015 |  | 2014 |  | 2015 |  | 2014 |
