Retirement Benefits [Abstract] |
Employee Retirement Plans | EMPLOYEE RETIREMENT PLANS (a)Pension Plans U.S. Plans: The company maintains a non-contributory defined benefit plan for its union employees at the Elgin, Illinois facility. Benefits are determined based upon retirement age and years of service with the company. This defined benefit plan was frozen on April 30, 2002, and no further benefits accrue to the participants beyond this date. Plan participants will receive or continue to receive payments for benefits earned on or prior to April 30, 2002 upon reaching retirement age. The company maintains a non-contributory defined benefit plan for its employees at the Smithville, Tennessee facility. Benefits are determined based upon retirement age and years of service with the company. This defined benefit plan was frozen on April 1, 2008, and no further benefits accrue to the participants beyond this date. Plan participants will receive or continue to receive payments for benefits earned on or prior to April 1, 2008 upon reaching retirement age. The company also maintains a retirement benefit agreement with its former Chairman ("Chairman Plan"). The retirement benefits are based upon a percentage of the former Chairman’s final base salary. Non-U.S. Plans: The company maintains a defined benefit plan for its employees at the Wrexham, the United Kingdom facility. Benefits are determined based upon retirement age and years of service with the company. This defined benefit plan was frozen on April 30, 2010 and no further benefits accrue to the participants beyond this date. Plan participants will receive or continue to receive payments for benefits earned on or prior to April 30, 2010 upon reaching retirement age. The company maintains several pension plans related to AGA and its subsidiaries (collectively, the "AGA Group"), the most significant being the Aga Rangemaster Group Pension Scheme in the United Kingdom. Membership in the plan on a defined benefit basis of pension provision was closed to new entrants in 2001. The plan became open to new entrants on a defined contribution basis of pension provision in 2002 but was generally closed to new entrants on this basis during 2014. In December 2020, it was agreed that the Group Pension Scheme will be closed to future pension accruals effective April 5, 2021. The other, much smaller, defined benefit pension plans operating within the AGA Group cover employees in France and the United Kingdom. All pension plan assets are held in separate trust funds although the net defined benefit pension obligations are included in the company's consolidated balance sheet. A summary of the plans’ net periodic pension cost, benefit obligations, funded status, and net balance sheet position is as follows (dollars in thousands)

The company has engaged non-affiliated third-party professional investment advisors to assist the company in developing its investment policy and establishing asset allocations. The company's overall investment objective is to provide a return, that along with company contributions, is expected to meet future benefit payments. Investment policy is established in consideration of anticipated future timing of benefit payments under the plans. The anticipated duration of the investment and the potential for investment losses during that period are carefully weighed against the potential for appreciation when making investment decisions. The company routinely monitors the performance of investments made under the plans and reviews investment policy in consideration of changes made to the plans or expected changes in the timing of future benefit payments. The assets of the plans were invested in the following classes of securities (none of which were securities of the company): U.S. Plans:
| Target Allocation |  | Percentage of Plan Assets
|  |  | 2022 |  | 2021
Equity | 48 | % |  | 45 | % |  | 53 | %

The fair value of the Level 1 assets is based on observable, quoted market prices of the identical underlying security in an active market. The fair value of the Level 2 assets is primarily based on market observable inputs to quoted market prices, benchmark yields and broker/dealer quotes. Level 3 inputs, as applicable, represent unobservable inputs that reflect assumptions developed by management to measure assets at fair value. The expected return on assets is developed in consideration of the anticipated duration of investment period for assets held by the plan, the allocation of assets in the plan, and the historical returns for plan assets. Estimated future benefit payments under the plans are as follows (dollars in thousands):
| U.S. Plans |  | Non-U.S. Plans
2023 | $ | 1,814 |  |  | $ | 55,341 |
2024 | 1,822 |  |  | 55,551 |
2025 | 1,841 |  |  | 56,522 |
2026 | 1,784 |  |  | 56,243 |
2027 through 2032 | 11,573 |  |  | 338,542 |
Expected contributions to the U.S. Plans and Non-U.S. Plans to be made in 2023 are $0.3 million and $5.6 million, respectively. (b)Defined Contribution Plans As of December 31, 2022, the company maintained two separate defined contribution 401(k) savings plans covering all employees in the United States. These two plans separately cover the union employees at the Elgin, Illinois facility and all other remaining union and non-union employees in the United States. The company also maintained defined contribution plans for its UK based employees.
