Compensation and Retirement Disclosure [Abstract] |
Pension and Other Postretirement Benefits Disclosure [Text Block] | ## 14. Employee Benefit Plans The Company has a profit sharing and thrift employee benefit plan in effect for all eligible employees. Company contributions under this defined contribution plan are based upon a percentage of income with limitations as defined by the plan. Contributions for the years ended December 31, 2017, 2016 and 2015 amounted to $3.4 million, $4.6 million, and $3.4 million, respectively. The Company also has an employee benefit plan in effect for certain non-union hourly employees. Company contributions under this defined contribution plan are based upon a percentage of income with limitations as defined by the plan. Contributions for the years ended December 31, 2017, 2016 and 2015 amounted to $0.6 million, $0.6 million and $0.7 million, respectively. The Company also has a registered retirement saving plan for certain Canadian employees, contributions to this plan for the year ended December 31, 2017 amounted to $0.1 million. The Company contributes to a number of multiemployer defined benefit pension plans under the terms of collective-bargaining agreements that cover its union-represented employees, who are represented by over 100 local unions. The related collective-bargaining agreements between those organizations and the Company, which specify the rate at which the Company must contribute to the multi-employer defined pension plan, expire at different times between 2018 and 2020. The risks of participating in these multiemployer defined benefit pension plans are different from single-employer plans in the following aspects:
| 1) | Assets contributed to the multiemployer plan by one employer may be used to provide benefits to employees of other participating employers.
| 2) | If a participating employer stops contributing to a plan, the unfunded obligations of the plan may be borne by the remaining participating employers.
| 3) | If the Company chooses to stop participating in a multiemployer plan, it may be required to pay the plan an amount based on the underfunded status of the plan, referred to as a withdrawal liability.
The amount of additional funds, if any, that the Company may be obligated to contribute to these plans in the future cannot be estimated due to uncertainty of the future levels of work that require the specific use of union employees covered by these plans, as well as the future contribution levels and possible surcharges on contributions applicable to these plans. The following table summarizes plan information relating to the Company’s participation in multi-employer defined benefit pension plans, including company contributions for the last three years, the status under the Pension Protection Act of 2006, as amended by the Consolidated and Further Continuing Appropriations Act of 2015 (“PPA”) of the plans and whether the plans are subject to a funding improvement or rehabilitation plan, or contribution surcharges. The most recent zone status is for the plan’s year-end indicated in the table. The zone status is based on information that the Company received from the plan, as well as from publicly available information on the U.S. Department of Labor website. The PPA zone status for the plan year ended on December 31, 2017 has not been listed because Forms 5500 were not yet available. Among other factors, plans in the red “critical” zone are generally less than 65 percent funded, plans in the yellow “endangered” zone are between 65 and 80 percent funded, and plans in the green zone are at least 80 percent funded. Also listed in the table below are the Company’s contributions to defined contribution plans. Information in the table has been presented separately for individually significant plans and in the aggregate for all other plans.
