Retirement Benefits [Abstract]
Postemployment Benefits Disclosure	Employee Benefit PlansThe Company maintains a trusteed defined contribution retirement plan which is in effect for substantially all domestic employees meeting the eligibility requirements. 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 in excess of IRS limitations. 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, 2023, both total investments and obligations under SERP were $8.4 million, of which $2.7 million were short term and $5.7 million were long term. As of June 30, 2022, both total investments and obligations under SERP were $10.4 million, of which $2.6 million were short term and $7.8 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. The change in net unrealized holding gains for both the nine months ended March 31, 2023 and 2022 was approximately $0.1 million and $(1.1) million, respectively.The Company established and maintains severance plans for all domestic employees and other postemployment plans for certain foreign subsidiaries. There are no statutory requirements for us to contribute to the plans, nor do employees contribute to the plans. The plans hold no assets. Benefits are paid using available cash on hand when eligible employees meet plan qualifications for payment. Net periodic benefit costs were not material for the nine months ended March 31, 2023 and 2022.
