Postemployment Benefits [Abstract]  
Compensation and Employee Benefit Plans [Text Block] Defined Benefit PlanIn connection with the acquisition of Arnold, the Company has a defined benefit plan covering substantially all of Arnold’s employees at its Lupfig, Switzerland location. The benefits are based on years of service and the employees’ highest average compensation during the specific period.
During the year ended December 31, 2020, Arnold terminated certain employees at the Switzerland location who were participants in the defined benefit plan. The termination of the employees resulted in a decrease in the accumulated benefit obligation liability in 2020. A curtailment loss of $0.1 million and $0.4 million was recognized during the years ended December 31, 2021 and 2020, respectively.
The following table sets forth the plan’s funded status and amounts recognized in the Company’s consolidated balance sheets at December 31, 2021 and 2020:

The Company considers the historical level of long-term returns and the current level of expected long-term returns for the plan assets, as well as the current and expected allocation of assets when developing its expected long-term rate of return on assets assumption. The assumptions used for the plan are based upon customary rates and practices for the location of the Company.
Arnold expects to contribute approximately $0.3 million to the defined benefit plan in 2022.
The following presents the benefit payments which are expected to be paid for the plan in each year indicated (in thousands):
2022$451 
2023460 
2024682 
2025597

Asset management objectives include maintaining an adequate level of diversification to reduce interest rate and market risk and providing adequate liquidity to meet immediate and future benefit payment requirements.
The assets of the plan are reinsured in their entirety with Swiss Life Ltd. (“Swiss Life”) within the framework of the corresponding contracts with Swiss Life Collective BVG Foundation and Swiss Life Complementary Foundation. The assets are guaranteed by the insurance company and pooled with the assets of other participating employers. The allocation of pension plan assets by category in Swiss Life’s group life portfolio is as follows at December 31, 2021:
Fixed income bonds and securities63 %
Real estate20 %
Equities and investment funds13 %
Certificates of deposit and cash and cash equivalents2 %
Other investments2 %
100 %
The plan assets are pooled with assets of other participating employers and are not separable; therefore the fair values of the pension plan assets at December 31, 2021 and 2020 were considered Level 3.
