Postemployment Benefits [Abstract]
Employee Benefit Plans	Note 10 Employee Benefit Plans We sponsor 401(k) savings plans whereby participating employees may elect to contribute up to 50% of their eligible wages up to the statutory contribution limit. Employees 50 years of age and older may contribute a further 75% of their eligible wages up to the statutory contribution limit. During 2017, employer contributions were $4.4 million. In certain entities outside the United States, we provide defined-benefit and defined contribution plans, many in accordance with local regulations. We typically deposit employer contributions with third party trustees, insurance trust funds, or government-managed accounts. We assumed pension plans in Germany related to an acquisition in 2012 and an acquisition in 2016 that covers certain German employees with over ten years of active service and provides benefits based on length of service and final pensionable earnings. There are no segregated pension fund assets under either of the plans assumed. The 2012 pension liability is insured and we have pledged the insurance contracts to the pensioners. Accordingly, the contracts are now considered to be a plan asset. As the plan assets are insurance contracts, the Company does not control the investment strategy and thus cannot influence the return on investments. The insurance payments are guaranteed by the insurer and should the insurer default on its obligation, the security fund for insurance companies in Germany would assume the contracts. The 2016 pension liability is not insured. As of October 1, 2017, the fair value of the pension plan assets from the 2012 acquisition was $4.3 million and the fair value of the pension plan benefit obligations from 2012 and 2016 acquisitions were $6.6 million and $3.9 million, respectively. During 2016, we recorded an unrealized actuarial loss on pension benefits of $3.9 million in other comprehensive income due to a reduction in the discount rate assumption used to determine benefit obligations from 2.1% to 1.0% and 2.8% to 1.6% from the 2012 and 2016 acquisitions respectively. There are no employer contributions expected in the next twelve months.
