Retirement Benefits [Abstract] |
Pension and Other Postretirement Benefits | Pension and Other Postretirement Benefits We sponsor defined benefit pension plans and defined contribution plans that cover substantially all employees in Canada, the Netherlands, the United Kingdom, the U.S., and certain employees in Germany, France, and Japan. We closed the U.S. defined benefit pension plan to new entrants effective January 1, 2010. Employees who were not active participants in the U.S. defined benefit pension plan on December 31, 2009, are not eligible to participate in the plan. During 2017, we sold our MCS business and its associated pension liabilities (see Note 4). Annual contributions to retirement plans equal or exceed the minimum funding requirements of applicable local regulations. The assets of the funded pension plans we sponsor are maintained in various trusts and are invested primarily in equity and fixed income securities. Benefits provided to employees under defined contribution plans include cash contributions by the Company based on either hours worked by the employee or a percentage of the employee’s compensation. Defined contribution expense for 2017, 2016, and 2015 was $13.9 million, $13.5 million, and $12.6 million, respectively. We sponsor unfunded postretirement medical and life insurance benefit plans for certain of our employees in Canada and the U.S. The medical benefit portion of the U.S. plan is only for employees who retired prior to 1989 as well as certain other employees who were near retirement and elected to receive certain benefits. The following tables provide a reconciliation of the changes in the plans’ benefit obligations and fair value of assets as well as a statement of the funded status and balance sheet reporting for these plans.

The accumulated benefit obligation for all defined benefit pension plans was $269.2 million and $253.9 million at December 31, 2017 and 2016, respectively. The projected benefit obligation, accumulated benefit obligation, and fair value of plan assets for the pension plans with an accumulated benefit obligation in excess of plan assets were $215.6 million, $212.7 million, and $138.5 million, respectively, as of December 31, 2017, and were $205.8 million, $203.1 million, and $128.5 million, respectively, as of December 31, 2016. The projected benefit obligation, accumulated benefit obligation, and fair value of plan assets for pension plans with an accumulated benefit obligation less than plan assets were $56.5 million, $56.5 million, and $59.6 million, respectively, as of December 31, 2017 and were $50.7 million, $50.7 million, and $53.9 million, respectively, as of December 31, 2016. The following table provides the components of net periodic benefit costs for the plans.

During 2016 and 2015, we recorded settlement losses totaling $7.6 million and $0.1 million, respectively. These settlement losses were the result of lump-sum payments to participants that exceeded the sum of the pension plans’ respective annual service cost and interest cost amounts. The following table presents the assumptions used in determining the benefit obligations and the net periodic benefit cost amounts.

Plan assets are invested using a total return investment approach whereby a mix of equity securities and fixed income securities are used to preserve asset values, diversify risk, and achieve our target investment return benchmark. Investment strategies and asset allocations are based on consideration of the plan liabilities, the plan’s funded status, and our financial condition. Investment performance and asset allocation are measured and monitored on an ongoing basis. Plan assets are managed in a balanced portfolio comprised of two major components: an equity portion and a fixed income portion. The expected role of equity investments is to maximize the long-term real growth of assets, while the role of fixed income investments is to generate current income, provide for more stable periodic returns, and provide some protection against a prolonged decline in the market value of equity investments. Absent regulatory or statutory limitations, the target asset allocation for the investment of the assets for our ongoing pension plans is 30-40% in fixed income securities and 60-70% in equity securities and for our pension plans where the majority of the participants are in payment or terminated vested status is 75-80% in fixed income securities and 20-25% in equity securities. Equity securities include U.S. and international equity, primarily invested through investment funds. Fixed income securities include government securities and investment grade corporate bonds, primarily invested through investment funds and group insurance contracts. We develop our expected long-term rate of return assumptions based on the historical rates of returns for equity and fixed income securities of the type in which our plans invest. The expected long-term rate of return on plan assets reflects the average rate of earnings expected on the invested assets and future assets to be invested to provide for the benefits included in the projected benefit obligation. We use historic plan asset returns combined with current market conditions to estimate the rate of return. The expected rate of return on plan assets is a long-term assumption based on an analysis of historical and forward looking returns considering the plan’s actual and target asset mix. The following table presents the fair values of the pension plan assets by asset category.

(a) | This category includes investments in actively managed and indexed investment funds that invest in a diversified pool of equity securities of companies located in the U.S., Canada, Western Europe and other developed countries throughout the world. The funds are valued using the net asset value method in which an average of the market prices for the underlying investments is used to value the fund. Funds valued using the net asset value method are not included in the fair value hierarchy.
(b) | This category includes investments in investment funds that invest in U.S. treasuries; other national, state and local government bonds; and corporate bonds of highly rated companies from diversified industries. The funds are valued using the net asset value method in which an average of the market prices for the underlying investments is used to value the fund. Funds valued using the net asset value method are not included in the fair value hierarchy.
(c) | This category includes guaranteed insurance contracts.
The plans do not invest in individual securities. All investments are through well diversified investment funds. As a result, there are no significant concentrations of risk within the plan assets. The following table reflects the benefits as of December 31, 2017 expected to be paid in each of the next five years and in the aggregate for the five years thereafter from our pension and other postretirement plans. Because our other postretirement plans are unfunded, the anticipated benefits with respect to these plans will come from our own assets. Because our pension plans are primarily funded plans, the anticipated benefits with respect to these plans will come primarily from the trusts established for these plans.

We anticipate contributing $4.6 million and $1.6 million to our pension and other postretirement plans, respectively, during 2018. The pre-tax amounts in accumulated other comprehensive loss that have not yet been recognized as components of net periodic benefit cost at December 31, 2017, the changes in these amounts during the year ended December 31, 2017, and the expected amortization of these amounts as components of net periodic benefit cost for the year ended December 31, 2017, are as follows.
