Retirement Benefits [Abstract]
Investment	The Company also maintains a supplemental employee retirement plan (“SERP”) for executives and other key employees which enables them to defer cash compensation on a pre-tax basis and restore amounts that would otherwise be payable under our tax-qualified retirement plans if the IRS did not have limits on includable compensation and maximum benefits. The SERP is structured as a rabbi trust, and therefore, assets in the SERP portfolio are subject to creditor claims in the event of bankruptcy. We recognize SERP investment assets on the balance sheet at current fair value. A SERP liability of the same amount is recorded on the balance sheet representing an obligation to distribute SERP funds to participants. As of March 31, 2024, both total investments and obligations under SERP were $5.4 million, of which $0.3 million were short term and $5.1 million were long term. As of June 30, 2023, both total investments and obligations under SERP were $8.7 million, of which $2.7 million were short term and $6.0 million were long term. The SERP investment assets are classified as trading, and accordingly, realized and unrealized gains and losses are recognized in the Other Income (Expense) category on our Condensed Consolidated Statements of Income. Adjustments made to revalue the SERP liability are also recognized in income as selling and administrative expenses and offset valuation adjustments on SERP investment assets.
