Compensation and Retirement Disclosure [Abstract]
Employee benefit plans [Text Block]	EMPLOYEE BENEFIT PLANS Pension Plans Employee retirement plans have been established in some foreign countries in accordance with the legal requirements and customs in the countries involved. The majority of employees in Europe, Asia and Canada are covered by defined benefit, multi-employer or defined contribution pension plans. The benefits provided by these plans are based primarily on years of service and employees’ compensation near retirement. Employees in the U.S. are covered by a profit sharing 401(k) plan, which is a defined contribution plan. Employees in The Netherlands participate with other companies in making collectively-bargained payments to the Metal-Electro Industry pension fund. We are responsible for the employer contributions to this fund, but are not obligated to make additional payments to cover any underfunded portions. Pension costs relating to this multi-employer plan were $4.7 million, $6.0 million and $6.8 million in 2011, 2010 and 2009, respectively. Outside the U.S. and The Netherlands, employees are covered under various defined contribution and defined benefit plans as required by local law. Plan costs for our defined contribution plans outside the U.S. and The Netherlands totaled $2.2 million in 2011, $1.4 million in 2010 and $1.5 million in 2009. Plan costs for our defined benefit pension plans were $0.1 million in 2011, $0.1 million in 2010 and $0.5 million in 2009. Obligations under the defined benefit pension plans are not funded. A liability for the projected benefit obligations of these plans of $1.7 million and $1.8 million was included in other non-current liabilities as of December 31, 2011 and 2010, respectively. Unrealized gains recorded in other comprehensive income related to the additional minimum pension liability for these plans were insignificant in 2011, 2010 and 2009. Due to the immateriality of these defined benefit pension plan costs, we have not included all required disclosures. Profit Share and Variable Compensation Programs We maintain an Employee Profit Share Plan and a Management Variable Compensation Plan for management-level employees to reward achievement of corporate and individual objectives. The Compensation Committee of the Board of Directors generally determines the structure of the overall incentive program at the beginning of each year. In setting the structure and the amount of the overall target incentive pool, the Compensation Committee considers potential size of the pool in relation to our earnings and other financial estimates, the achievability of the corporate targets under the plan, historical payouts under the plan and other factors. The total cost of these plans was $24.7 million in 2011, $12.5 million in 2010 and $6.1 million in 2009. Profit Sharing 401(k) Plan We maintain a profit sharing 401(k) plan that covers substantially all U.S. employees. Employees may elect to defer a portion of their compensation, and we may contribute an amount approved by the Board of Directors. We match 100% of employee contributions to the 401(k) plan up to 3% of each employee’s eligible compensation. Employees must meet certain requirements to be eligible for the matching contribution. We contributed $1.5 million in 2011, $1.5 million in 2010 and $1.3 million in 2009 to this plan. Our 401(k) plan does not allow for the investment in shares of our common stock. Deferred Compensation Plan We maintain a deferred compensation plan (the “Plan”), which permits certain employees to defer payment of a portion of their annual compensation. We do not match deferrals or make any additional contributions to the Plan. Distributions from the Plan are generally payable as a lump sum payment or in multi-year installments as directed by the participant according to the Plan provisions. Undistributed amounts under the Plan are subject to the claims of our creditors. As of December 31, 2011 and 2010, the invested amounts under the Plan totaled $2.8 million and $2.9 million, respectively, and were recorded on our balance sheets as non-current investments in marketable securities and as a long-term liability to recognize undistributed amounts due to employees.
