Subsequent Events [Abstract]
SUBSEQUENT EVENT	SUBSEQUENT EVENT:In November 2021, subsequent to the date of the balance sheet, the Company contributed $20,000 to the DB Plan. Also in November 2021, lump sum distributions of $178,230 from the DB Plan were made to plan participants, resulting in the settlement of a substantial portion of the DB Plan obligations. This settlement of the DB Plan obligations is expected to result in the recognition of a non-cash charge in excess of $30,000 in the first quarter of fiscal 2022. This amount represents the immediate recognition of a portion of the deferred AOCI balances related to the DB Plan, and is based on current estimates as of September 30, 2021. See Note 14, "Pension and Other Postretirement Plans" for further discussion.
