Retirement Benefits [Abstract] |
Employee Benefit Plans | Employee Benefit Plans Pension and Profit-Sharing Benefits The Company provides a defined contribution profit sharing plan for the benefit of substantially all the Company's domestic salaried and non-union hourly employees. The plan contains both contributory and noncontributory profit sharing arrangements, as defined. Aggregate charges included in the accompanying consolidated statement of operations under this plan were approximately $4.2 million, $3.8 million and $3.7 million in 2018, 2017 and 2016, respectively. Certain of the Company's non-U.S. and union hourly employees participate in defined benefit pension plans. Plan Assets, Expenses and Obligations Net periodic pension benefit expense recorded in the Company's consolidated statement of operations for defined benefit pension plans include the following components (dollars in thousands):
|  | Pension Benefit
|  | 2018 |  | 2017 |  | 2016
Service cost |  | $ | 1,120 |  |  | $ | 1,150 |  |  | $ | 950 |
Interest cost |  | 1,100 |  |  | 1,290 |  |  | 1,510 |
Expected return on plan assets |  | (1,520 | ) |  | (1,480 | ) |  | (1,610 | )
Settlements and curtailments |  | 2,620 |  |  | — |  |  | 1,330 |
Amortization of net loss |  | 860 |  |  | 1,010 |  |  | 930 |
Net periodic benefit expense |  | $ | 4,180 |  |  | $ | 1,970 |  |  | $ | 3,110 |
The service cost component of net periodic benefit cost is recorded in cost of goods sold and selling, general and administrative expenses, while non-service cost components are recorded in other expense, net in the accompanying consolidated statement of operations. During 2018, the Company recognized one-time settlement and curtailment charges of approximately $2.6 million, of which approximately $2.5 million was due to the purchase of an annuity contract to transfer certain U.S. retiree defined benefit obligations to an insurance company. The annuity contract was funded by plan assets. During 2016, the Company recognized one-time settlement and curtailment charges of approximately $1.3 million primarily due to lump sum payments in the United States and the United Kingdom. The estimated net actuarial loss and prior service cost for defined benefit pension plans that is expected to be amortized from AOCI into net periodic benefit expense in 2019 is approximately $0.6 million. Actuarial valuations of the Company's defined benefit pension plans were prepared as of December 31, 2018, 2017 and 2016. Weighted average assumptions used in accounting for the U.S. defined benefit pension plans are as follows:
|  | Pension Benefit
|  | 2018 |  | 2017 |  | 2016
Discount rate for obligations |  | 4.50 | % |  | 3.76 | % |  | 4.35 | %
Discount rate for benefit costs |  | 4.37 | % |  | 4.35 | % |  | 4.62 | %
Rate of increase in compensation levels |  | N/A |  |  | N/A |  |  | N/A |
Expected long-term rate of return on plan assets |  | 7.13 | % |  | 7.13 | % |  | 7.13 | %
The Company utilizes a high-quality (Aa or greater) corporate bond yield curve as the basis for its domestic discount rate for its pension benefit plans. Management believes this yield curve removes the impact of including additional required corporate bond yields (potentially considered in the above-median curve) resulting from the uncertain economic climate that does not necessarily reflect the general trend in high-quality interest rates. Weighted average assumptions used in accounting for the non-U.S. defined benefit pension plans are as follows:
|  | Pension Benefit
|  | 2018 |  | 2017 |  | 2016
Discount rate for obligations |  | 3.00 | % |  | 2.60 | % |  | 2.80 | %
Discount rate for benefit costs |  | 2.60 | % |  | 2.80 | % |  | 3.80 | %
Rate of increase in compensation levels |  | 3.30 | % |  | 3.30 | % |  | 3.90 | %
Expected long-term rate of return on plan assets |  | 4.60 | % |  | 4.60 | % |  | 4.90 | %

The assumptions regarding discount rates and expected return on plan assets can have a significant impact on amounts reported for benefit plans. A 25 basis point change in benefit obligation discount rates or 50 basis point change in expected return on plan assets would have the following effect (dollars in thousands):
|  | Pension Benefit
|  | December 31, 2018 Benefit Obligation |  | 2018 Expense
Discount rate |  |  |  |
25 basis point increase |  | $ | (1,120 | ) |  | $ | (90 | )
25 basis point decrease |  | $ | 1,210 |  |  | $ | 100 |
Expected return on assets |  |  |  |
50 basis point increase |  | N/A |  |  | $ | (130 | )
50 basis point decrease |  | N/A |  |  | $ | 130 |
The Company expects to make contributions of approximately $1.9 million to fund its pension plans during 2019. Plan Assets The Company's overall investment goal is to provide for capital growth with a moderate level of volatility by investing assets in targeted allocation ranges. Specific long term investment goals include total investment return, diversity to reduce volatility and risk, and to achieve an asset allocation profile that reflects the general nature and sensitivity of the plans' liabilities. Investment goals are established after a comprehensive review of current and projected financial statement requirements, plan assets and liability structure, market returns and risks as well as special requirements of the plans. The Company reviews investment goals and actual results annually to determine whether stated objectives are still relevant and the continued feasibility of achieving the objectives. The actual weighted average asset allocation of the Company's domestic and foreign pension plans' assets at December 31, 2018 and 2017 and target allocations by class, were as follows:
|  | Domestic Pension |  | Foreign Pension
|  |  |  | Actual |  |  |  | Actual
|  | Target |  | 2018 |  | 2017 |  | Target |  | 2018 |  | 2017
Equity securities |  | 60 | % |  | 58 | % |  | 63 | % |  | 33 | % |  | 29 | % |  | 30 | %
Fixed income |  | 36 | % |  | 39 | % |  | 36 | % |  | 45 | % |  | 47 | % |  | 46 | %
Diversified growth(a) |  | — | % |  | — | % |  | — | % |  | 22 | % |  | 24 | % |  | 24 | %
Cash and other |  | 4 | % |  | 3 | % |  | 1 | % |  | — |  |  | — | % |  | — | %
Total |  | 100 | % |  | 100 | % |  | 100 | % |  | 100 | % |  | 100 | % |  | 100 | %
________________________________________ (a) Diversified growth funds invest in a broad range of asset classes including equities, investment grade and high yield bonds, commodities, property, private equity, infrastructure and currencies. Actual allocations to each asset vary from target allocations due to periodic investment strategy changes, market value fluctuations and the timing of benefit payments and contributions. The expected long-term rate of return for both the domestic and foreign plans' total assets is based on the expected return of each of the above categories, weighted based on the target allocation for each class. Actual allocation is reviewed regularly and investments are rebalanced to their targeted allocation range when deemed appropriate. In managing the plan assets, the Company reviews and manages risk associated with the funded status risk, interest rate risk, market risk, liquidity risk and operational risk. Investment policies reflect the unique circumstances of the respective plans and include requirements designed to mitigate these risks by including quality and diversification standards. The following table summarizes the level under the fair value hierarchy (see Note 3, "Summary of Significant Accounting Policies") that the Company's pension plan assets are measured, on a recurring basis as of December 31, 2018 (dollars in thousands):
|  | Total |  | Level 1 |  | Level 2 |  | Level 3
Plan assets subject to leveling |  |  |  |  |  |  |  |

________________________________________ (a) Certain investments that are measured at fair value using the net asset value per share as a practical expedient have not been classified in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amount presented in the fair value of plan assets. The following benefit payments, which reflect expected future service, as appropriate, are expected to be paid (dollars in thousands):
