Employee Benefit Plans [Abstract] |
Pension and Other Postretirement Benefits Disclosure [Text Block] | 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 statement of operations under this plan for both continuing and discontinued operations were approximately $4.5 million, $4.2 million and $4.2 million in 2011, 2010 and 2009, respectively. The Company's foreign and union hourly employees participate in defined benefit pension plans. Postretirement Benefits The Company provides postretirement medical and life insurance benefits, none of which are pre-funded, for certain of its active and retired employees. Plan Assets, Expenses and Obligations Plan assets, expenses and obligations for pension and postretirement benefit plans disclosed herein include both continuing and discontinued operations. Net periodic pension and postretirement benefit expense (income) recorded in the Company's statement of operations for defined benefit pension plans and postretirement benefit plans include the following components:
|  | Pension Benefit |  | Postretirement Benefit
|  | 2011 |  | 2010 |  | 2009 |  | 2011 |  | 2010 |  | 2009

In 2009, the Company settled obligations outstanding under certain of its postretirement benefit plans, resulting in the recognition of previously deferred gains of approximately $0.1 million. The estimated net actuarial loss and prior service cost for the defined benefit pension and postretirement benefit plans that is expected to be amortized from accumulated other comprehensive income into net periodic benefit cost in 2012 is $0.7 million. Actuarial valuations of the Company's defined benefit pension and postretirement plans were prepared as of December 31, 2011, 2010 and 2009. Weighted-average assumptions used in accounting for the U.S. defined benefit pension plans and postretirement benefit plans are as follows:
|  | Pension Benefit |  | Postretirement Benefit
|  | 2011 |  | 2010 |  | 2009 |  | 2011 |  | 2010 |  | 2009
Discount rate for obligations |  | 4.78 | % |  | 5.50 | % |  | 6.13 | % |  | 4.54 | % |  | 4.66 | % |  | 5.25 | %
Discount rate for benefit costs |  | 5.50 | % |  | 6.13 | % |  | 6.38 | % |  | 4.66 | % |  | 5.25 | % |  | 6.65 | %
Rate of increase in compensation levels |  | N/A |  |  | N/A |  |  | N/A |  |  | N/A |  |  | N/A |  |  | N/A |
Expected long-term rate of return on plan assets |  | 7.75 | % |  | 8.00 | % |  | 8.25 | % |  | N/A |  |  | N/A |  |  | N/A |
The Company utilizes a high-quality (Aa) corporate bond yield curve as the basis for its domestic discount rate for its pension and postretirement 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. Actuarial valuations of the Company's non-U.S. defined benefit pension plans were prepared as of December 31, 2011, 2010 and 2009. Weighted-average assumptions used in accounting for the non-U.S. defined benefit pension plans are as follows:
|  | Pension Benefit
|  | 2011 |  | 2010 |  | 2009
Discount rate for obligations |  | 4.80 | % |  | 5.50 | % |  | 5.90 | %
Discount rate for benefit costs |  | 5.50 | % |  | 5.90 | % |  | 6.70 | %
Rate of increase in compensation levels |  | 4.00 | % |  | 4.00 | % |  | 4.20 | %
Expected long-term rate of return on plan assets |  | 7.00 | % |  | 7.00 | % |  | 7.30 | %

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 affect:

The Company expects to make contributions of approximately $5.8 million to fund its pension plans and $0.1 million to fund its postretirement benefit payments during 2012. 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, 2011 and 2010 and target allocations by class, were as follows:
|  | Domestic Pension |  | Foreign Pension
|  |  |  | Actual |  |  |  | Actual
|  | Target |  | 2011 |  | 2010 |  | Target |  | 2011 |  | 2010
Equity securities |  | 50%-70% |  |  | 57 | % |  | 58 | % |  | 40 | % |  | 35 | % |  | 41 | %
Debt securities |  | 30%-50% |  |  | 37 | % |  | 35 | % |  | 60 | % |  | 65 | % |  | 59 | %
Cash |  | — |  |  | 6 | % |  | 7 | % |  | — |  |  | — | % |  | — | %
Total |  | 100 | % |  | 100 | % |  | 100 | % |  | 100 | % |  | 100 | % |  | 100 | %
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 rebalancing investments to their targeted allocation range is performed 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) that the Company's pension plan assets are measured on a recurring basis as of December 31, 2011:
