Deferred Compensation Plan
Defined Benefit Plan Disclosure [Line Items]
Deferred compensation arrangements, overall, description	We maintain a Non-Qualified Deferred Compensation Plan (the “Deferred Compensation Plan”) for executive officers, key employees and members of the Board of Directors (the “Board”). The Deferred Compensation Plan allows eligible participants to defer the receipt of eligible compensation, including equity awards, until designated future dates. We offset our obligations under the Deferred Compensation Plan by investing in the actual underlying investments. These investments are classified as trading securities and are carried at fair value. At December 31, 2016, these investments totaled approximately $6.3 million. All gains and losses in these investments are materially offset by corresponding gains and losses in the deferred compensation plan liabilities.

Pension Plan, Defined Benefit
Defined Benefit Plan Disclosure [Line Items]
Defined benefit plans, general information	In connection with the Zetex acquisition, we adopted a contributory defined benefit plan that covers certain employees in the U.K. The defined benefit plan is closed to new entrants and frozen with respect to future benefit accruals. The retirement benefit is based on the final average compensation and service of each eligible employee. We determined the fair value of the defined benefit plan assets and utilize an annual measurement date of December 31. At subsequent measurement dates, defined benefit plan assets will be determined based on fair value. Defined benefit plan assets consist of a diverse range of listed and unlisted securities including corporate bonds and mutual funds and are denominated in the currency in which the benefits will be paid and that have terms to maturity approximating the terms of the related pension liability. The net pension and supplemental retirement benefit obligations and the related periodic costs are based on, among other things, assumptions of the discount rate, estimated return on plan assets and mortality rates. These obligations and related periodic costs are measured using actuarial techniques and assumptions.
Defined benefit plan, pension, method to determine vested benefit obligation	The projected unit credit method is the actuarial cost method used to compute the pension liabilities and related expenses.

Defined benefit plan, estimated future employer contributions in current fiscal year, description	We adopted a payment plan with the trustees of the defined benefit plan, in which we would make annual contributions each year through 2030, of approximately GPB 2 million (approximately $2.4 million based on a GBP:USD exchange rate of 1.2). The annual contributions were expected to meet the deficit disclosed in the plan as of April 5, 2013 by December 31, 2030. The trustees are required to review the funding position every three years, and a further review was carried out as of April 5, 2016. The outcome of the review, as agreed with the trustees during the first quarter of 2017, was that contributions would continue at the existing level until December 31, 2029.
