Retirement Benefits [Abstract] |
Benefit Plans and Collective Bargaining Agreements | Benefit Plans and Collective Bargaining Agreements The Company has a 401(k) Employee Stock Ownership Plan (the "401(k)/ESOP Plan") covering all non-union employees. Employees could contribute to the 401(k)/ESOP Plan up to 100% of their wages with a maximum of $19,500 for 2021. Under the Economic Growth and Tax Relief Reconciliation Act, employees who are age 50 or older could contribute an additional $6,500 per year for a maximum of $26,000 for 2021. Contributions by the employees are invested in one or more funds at the direction of the employee; however, employee contributions cannot be invested in Company stock. Contributions by the Company are made in accordance with the investment elections made by each participant for his or her deferral contributions. The Company contributes on behalf of each eligible participant a matching contribution equal to a percentage determined each year by the Board of Directors. For 2021 and 2020 the maximum was 100% of employee contributions up to a maximum of 4% of their eligible compensation. The matching contribution is applied to the employee accounts after each payroll. Matching contributions of approximately $0.7 million and $0.4 million were made for 2021 and 2020, respectively. The Company may also make a discretionary contribution, which if made, would be distributed to all eligible participants regardless of whether they contribute to the 401(k)/ESOP Plan. No discretionary contributions were made to the 401(k)/ESOP Plan in 2021 or 2020. The Company has a 401(k) and Profit Sharing Plan (the "Bristol Plan") covering all employees as part of the United Steel Workers of America, Local Union 4586 Collective Bargaining Agreement (the "Bristol CBA"). Employees could contribute to the Bristol Plan up to 60% of pretax annual compensation, as defined in the Bristol Plan, with a maximum of $19,500 for 2021. Under the Economic Growth and Tax Relief Reconciliation Act, employees who are age 50 or older could contribute an additional $6,500 per year for a maximum of $26,000 for 2021. During 2021, the Company contributed 4% of a participant's eligible compensation regardless of whether the participants contribute to the Bristol Plan. During 2020, the Company contributed 3% of a participant's eligible compensation from January to July and increased the amount to 4% for the remainder of the plan year. The Company's contributions were $0.3 million and $0.2 million for 2021 and 2020, respectively. Additional profit sharing amounts may also be contributed at the option of the Company's Board of Directors, which if made, would be allocated to participants based on the ratio of the participant's compensation to the total compensation of all participants eligible to participate in the Bristol Plan. No discretionary contributions were made to the Bristol Plan in 2021 or 2020. The Company also has a 401(k) Plan (the "DanChem Plan") covering substantially all employees at the DanChem facility.

For 2021 and 2020 the maximum was 100% of employee contributions up to the first 3% of their eligible compensation and 50% for employee contributions from 3% to 6%. The Company also maintains a Collective Bargaining Agreement (the "Danville CBA") with the United Food and Commercial Workers, Local Union 400 (the "Danville Union"), which represents employees at the Danville facility and is required to make additional quarterly contributions for hourly employees who had a hire date prior to June 1, 2013. Matching contributions of approximately $0.4 million were made for 2021. The Company maintains a Collective Bargaining Agreement (the "Munhall CBA") with the United Steel Workers of America, Local Union 5852-22 (the "Munhall Union"), which represents the employees at the Munhall facility. As a part of this Munhall CBA, the Company assumed the obligation of participating in the Steelworkers Pension Trust, a union-sponsored multi-employer defined benefit plan (the "Munhall Plan"), which covers all the Company's eligible Munhall Union employees. The Munhall Plan has a calendar plan year. Per the most recent available annual funding notice, the plan was at least 87% funded for the plan year ended December 31, 2020. Per the terms of the Munhall CBA the Company contributes 4.25% of each participant's eligible compensation for the 2020 plan year. Munhall Union employees make no contributions to the Munhall Plan. The Company's contributions to the Munhall Plan totaled $0.2 million for the year ended December 31, 2021 and 2020, respectively. Additionally, as part of the Munhall CBA, members of the union are eligible to make deferral contributions to the Company's 401(k)/ESOP Plan per the plan guidelines; however they do not receive matching contributions of the 401(k)/ESOP Plan. The Company maintains a Collective Bargaining Agreement (the "Mineral Ridge CBA") with the United Steel Workers of America, Local Union 4564-07, which represents employees at the Specialty-Mineral Ridge facility.
