Retirement Benefits [Abstract] |
Pensions and Other Postretirement Benefit Plans | 4. Pensions and Other Postretirement Benefit Plans Pension Plans The Company has defined benefit pension plans covering certain U.S. and non-U.S. employees. The U.S. qualified defined benefit pension plan has been closed to new participants since October 1998 and, as of February 2009, benefits accrued under this plan were frozen. As a result of the freeze, employees covered by the pension plan will receive, at retirement, benefits accrued through February 2009, but no benefits accrue after that date. Benefit accruals under the U.S. Supplemental Executive Retirement Plan (“SERP”), which is an unfunded plan, were similarly frozen. The U.S. pension plan accounts for 44 percent of consolidated pension plan assets, and 45 percent of consolidated pension plan obligations. The eligibility, benefit formulas, and contribution requirements for plans outside of the U.S. vary by location. The December 31, 2020 benefit obligations for the U.S. pension and postretirement plans were calculated using the Pri-2012 mortality table with MP-2020 generational projection. For U.S. pension funding purposes, the Company uses the plan’s IRS-basis current liability as its funding target, which is determined based on mandated assumptions. Benefits under the Company's pension plan in Switzerland utilize a cash balance interest crediting rate for determination of plan liabilities. As of December 31, 2020, the benefit obligation for that plan amounted to $6.0 million. In addition to providing pension benefits, the Company provides various medical, dental, and life insurance benefits for certain retired United States employees. U.S. employees hired prior to 2005 may become eligible for these benefits if they reach normal retirement age while working for the Company. Benefits provided under this plan are subject to change. Retirees share in the cost of these benefits. Any new employees hired after January 2005 who wish to be covered under this plan will be responsible for the full cost of such benefits. In September 2008, we changed the cost-sharing arrangement under this program such that increases in health care costs are the responsibility of plan participants. In August 2013, we reduced the life insurance benefit for retirees and eliminated the benefit for active employees. The Company also provides certain postretirement life insurance benefits to retired employees in Canada. As of December 31, 2020, the accrued postretirement liability was $46.7 million in the U.S. and $1.3 million in Canada. The Company accrues the cost of providing postretirement benefits during the active service period of the employees. The Company currently funds the plans as claims are paid. Accounting guidance requires the recognition of the funded status of each defined benefit and other postretirement benefit plan. Each overfunded plan is recognized as an asset and each underfunded plan is recognized as a liability. Company pension plan data for U.S. and non-U.S. plans has been combined for both 2020 and 2019, except where indicated below. The Company’s pension and postretirement benefit costs and benefit obligations are based on actuarial valuations that are affected by many assumptions, the most significant of which are the assumed discount rate, expected rate of return on pension plan assets, and mortality. Each of the assumptions is reviewed and updated annually, as appropriate. The assumed rates of return for pension plan assets are determined for each major asset category based on historical rates of return for assets in that category and expectations of future rates of return based, in part, on simulated future capital market performance. The assumed discount rate is based on yields from a portfolio of currently available high-quality fixed-income investments with durations matching the expected future payments, based on the demographics of the plan participants and the plan provisions. Gains and losses arise from changes in the assumptions used to measure the benefit obligations, and experience different from what had been assumed, including asset returns different than what had been expected. The Company amortizes gains and losses in excess of a “corridor” over the average future service of the plan’s current participants. The corridor is defined as 10 percent of the greater of the plan’s projected benefit obligation or market-related value of plan assets. The market-related value of plan assets is also used to determine the expected return on plan assets component of net periodic cost. The Company’s market-related value for its U.S. plan is measured by first determining the absolute difference between the actual and the expected return on the plan assets. The absolute difference in excess of 5 percent of the expected return is added to the market-related value over two years; the remainder is added to the market-related value immediately. To the extent the Company’s unrecognized net losses and unrecognized prior service costs, including the amount recognized through accumulated other comprehensive income, are not reduced by future favorable plan experience, they will be recognized as a component of the net periodic cost in future years. The following table sets forth the plan benefit obligations:

During 2020, pension benefit obligations increased by $18.6 million, $13.3 million of which was driven by net actuarial losses, principally resulting from a lower discount rate. Other postretirement benefit obligations decreased by $6.4 million in 2020, as changes in demographic data assumptions which resulted from a 2020 experience study, were partially offset by lower discount rates. During 2019, lower average discount rates had the effect of significantly increasing both pension and other postretirement benefit obligations. The following sets forth information about plan assets:

Investment Strategy Our investment strategy for pension assets differs for the various countries in which we have defined benefit pension plans. Some of our defined benefit plans do not require funded trusts and, in those arrangements, the Company funds the plans on a “pay as you go” basis. The largest of the funded defined benefit plans is the United States plan. United States plan: During 2009, we changed our investment strategy for the United States pension plan by adopting a liability-driven investment strategy. Under this arrangement, the Company seeks to invest in assets that track closely to the discount rate that is used to measure the plan liabilities. Accordingly, the plan assets are primarily debt securities. The change in investment strategy is reflective of the Company’s 2008 decision to freeze benefit accruals under the plan. Non-United States plans: For the countries in which the Company has funded pension trusts, the investment strategy may also be liability driven or, in other cases, to achieve a competitive, total investment return, achieving diversification between and within asset classes and managing other risks. Investment objectives for each asset class are determined based on specific risks and investment opportunities identified. Actual allocations to each asset class vary from target allocations due to periodic investment strategy changes, market value fluctuations, the length of time it takes to fully implement investment allocation positions, and the timing of benefit payments and contributions. Fair-Value Measurements The following tables present plan assets as of December 31, 2020, and 2019, using the fair-value hierarchy, which has three levels based on the reliability of inputs used, as described in Note 18. Certain investments that are measured at fair value using net asset value (NAV) as a practical expedient are not required to be categorized in the fair value hierarchy table. The total fair value of these investments is included in the table below to permit reconciliation of the fair value hierarchy to amounts presented in the funded status table above. As of December 31, 2020 and 2019, there were no investments expected to be sold at a value materially different than NAV.

(1)Other includes hedged equity and absolute return strategies, and private equity. The Company has procedures to closely monitor the performance of these investments and compares asset valuations to audited financial statements of the funds. The targeted plan asset allocation is based on an analysis of the actuarial liabilities, a review of viable asset classes, and an analysis of the expected rate of return, risk, and other investment characteristics of various investment asset classes. At the end of 2020 and 2019, the projected benefit obligation, accumulated benefit obligation, and fair value of plan assets for pension plans with projected benefit obligation and an accumulated benefit obligation in excess of plan assets were as follows:
|  | Plans with projected benefit obligation in excess of plan assets
