Retirement Benefits [Abstract]  
RETIREMENT PLANS RETIREMENT PLANSThe Company sponsors a defined benefit retirement plan, or Benefit Plan, which covers eligible employees hired prior to February 1, 2007. The benefits are based on years of service and the employee’s five-year final average salary. Contributions are intended to provide for benefits attributable to service both to date and expected to be provided in the future. The Company funds the plan in accordance with the Employee Retirement Income Security Act of 1974 (ERISA). In April 2017, the Company froze the Benefit Plan as it relates to future benefit accruals for participants. The Company contributed $165,000 to the Benefit Plan in 2023.
Benefit Plan assets consist of equity, debt and short-term money market investment funds. The Benefit Plan’s current investment policy changed during the third quarter of 2018. The policy's strategy seeks to minimize the volatility of the funding ratio. This objective will result in a prescribed asset mix between "return seeking" assets (e.g., stocks) and a bond portfolio (e.g., long duration bonds) according to a pre-determined customized investment strategy based on the Benefit Plan's funded status as the primary input. This path will be used as a reference point as to the mix of assets, which by design will de-emphasize the return seeking portion as the funded status improves. At September 30, 2023, the investment mixes were approximately at 99% debt and 1% money market funds. At December 31, 2022, the investment mixes were approximately 21% equity, 78% debt, and 1% money market funds. Equity investments consist of a combination of individual equity securities plus value funds, growth funds, large cap funds and international stock funds. The weighted-average discount rate used in determining the periodic pension cost is 5.00% in 2023 and 2022. The expected long-term rate of return on plan assets is 5.00% for both fiscal 2023 and 2022. The long-term rate of return on Benefit Plan assets is based on the historical returns within the plan and expectations for future returns.
Total pension and retirement earnings for the Benefit Plan was as follows:

The Company has a Supplemental Executive Retirement Plan, or SERP, to restore to executives designated by the Compensation Committee of the Board of Directors the full benefits under the pension plan that would otherwise be restricted by certain limitations now imposed under the Internal Revenue Code. The SERP is currently unfunded. In April 2017, the Company froze the SERP as it relates to the accrual of additional benefits.
