Defined Benefit Pension Plans and Defined Benefit Postretirement Plans Disclosure [Abstract] |
Pension and other postretirement benefits | Pension and other postretirement benefits The Company has a number of defined benefit pension and postretirement plans covering eligible U.S. and non-U.S. employees. The defined benefit pension plans are noncontributory. The benefits under these plans are based primarily on years of service and employees’ pay near retirement. The Company’s funding policy for U.S. plans is to contribute annually, at a minimum, amounts required by applicable laws and regulations. Obligations under non-U.S. plans are systematically provided for by depositing funds with trustees or by book reserves. As of December 31, 2015, no further benefits are being accrued under the Company’s U.S. defined benefit pension plans and the Company’s other postretirement benefit plans, other than certain postretirement benefit plans covering employees subject to a collective bargaining agreement. The Company and certain of its subsidiaries provide medical, dental and life insurance benefits to pensioners or their survivors. The associated plans are unfunded and approved claims are paid from Company funds. The following table provides information regarding the components of the net benefit expense (income) of the Company's pension and postretirement benefit plans:

The following table provides the weighted average assumptions for United States and foreign plans used in determining benefit obligations:
| Pension |  | Other Benefits
| 2015 |  | 2014 |  | 2015 |  | 2014
Discount rate | 4.5 | % |  | 4.1 | % |  | 4.3 | % |  | 4.0 | %
Rate of compensation increase | 2.8 | % |  | 3.0 | % |  |  |  |
Initial healthcare trend rate |  |  |  |  | 8.4 | % |  | 7.3 | %
Ultimate healthcare trend rate |  |  |  |  | 5.0 | % |  | 5.0 | %
The discount rate represents the interest rate used to determine the present value of future cash flows currently expected to be required to settle the Company’s pension and other benefit obligations. The weighted average discount rates for United States pension plans and other benefit plans of 4.63% and 4.31%, respectively, were established by comparing the projection of expected benefit payments to the AA Above Median yield curve as of December 31, 2015. The expected benefit payments are discounted by each corresponding discount rate on the yield curve. For payments beyond 30 years, the Company extends the curve assuming that the discount rate derived in year 30 is extended to the end of the plan’s payment expectations. Once the present value of the string of benefit payments is established, the Company determines the single rate on the yield curve that, when applied to all obligations of the plan, will exactly match the previously determined present value. Effective December 31, 2015, the Company changed the method it uses to estimate the service and interest cost components of net periodic benefit cost for its pension and other postretirement benefits. Previously, the Company used a single equivalent discount rate to estimate the interest and service cost components of net periodic benefit cost. The single discount rate represented the constant annual rate that would be required to discount all future benefit payments related to past service from the date of expected future payment to the measurement date. Under the new method, these components are estimated by applying specific spot rates along the yield curve used by the Company in determining the benefit obligation to their underlying projected cash flow. This change in method provides a more precise estimate of service and interest costs by improving the correlation between projected cash flows and their corresponding spot rates and will not affect the measurement of the Company’s pension and postretirement benefit obligations. The Company accounted for this change as a change in accounting estimate, which is applied prospectively. Therefore, adoption of this change had no impact on the results for the year ended December 31, 2015. As part of the evaluation of pension and other postretirement assumptions, the Company applied assumptions for mortality and healthcare cost trends that incorporate generational white and blue collar mortality trends. In determining its benefit obligations, the Company used generational tables that take into consideration increases in plan participant longevity. The Company’s assumption for the Expected Return on Plan Assets is primarily based on the determination of an expected return for its current portfolio. This determination is made using assumptions for return and volatility of the portfolio. Asset class assumptions are set using a combination of empirical and forward-looking analysis. To the extent historical results have been affected by unsustainable trends or events, the effects of those trends are quantified and removed. The Company applies a variety of models for filtering historical data and isolating the fundamental characteristics of asset classes. These models provide empirical return estimates for each asset class, which are then reviewed and combined with a qualitative assessment of long term relationships between asset classes before a return estimate is finalized. The qualitative analysis is intended to provide an additional means for addressing the effect of unrealistic or unsustainable short-term valuations or trends, resulting in return levels and behavior the Company believes are more likely to prevail over long periods. Effective in 2015, the Company changed its Expected Return on Plan Assets of the United States pension plans from 8.50% to 8.25% to reflect modifications to assumptions resulting from the analysis described above. An increase in the assumed healthcare trend rate of 1% would increase the benefit obligation at December 31, 2015 by $3.8 million and would increase the 2015 benefit expense by $0.2 million. Decreasing this assumed rate by 1% would decrease the benefit obligation at December 31, 2015 by $3.3 million and would decrease the 2015 benefit expense by $0.2 million. The accumulated benefit obligation for all United States and foreign defined benefit pension plans was $421.2 million and $447.4 million for 2015 and 2014, respectively. All of the Company's pension plans had accumulated benefit obligations in excess of their respective plan assets as of December 31, 2015 and 2014. The Company’s investment objective is to achieve an enhanced long-term rate of return on plan assets, subject to a prudent level of portfolio risk, for the purpose of enhancing the availability of benefits for participants. These investments are primarily comprised of equity and fixed income mutual funds. The Company’s other investments are largely comprised of a hedge fund of funds and a structured credit fund. The equity funds are diversified in terms of domestic and international equity securities, as well as small, middle and large capitalization stocks. The Company’s target allocation percentage is as follows: equity securities (45%); fixed-income securities (35%) and other securities (20%). Equity funds are held for their expected return over inflation. Fixed-income funds are held for diversification relative to equities and as a partial hedge of interest rate risk with respect to plan liabilities. The other investments are held to further diversify assets within the plans and are designed to provide a mix of equity and bond like return with a bond like risk profile. The plans may also hold cash to meet liquidity requirements. Actual performance may not be consistent with the respective investment strategies. Investment risks and returns are measured and monitored on an ongoing basis through annual liability measurements and investment portfolio reviews to determine whether the asset allocation targets continue to represent an appropriate balance of expected risk and reward.
