Notes to Financial Statements
Subsequent Events [Text Block]	NOTE 12 – Subsequent Events: The Company is in the process of terminating its two noncontributory qualified defined benefit pension plans, which were fully funded as of March 31, 2021. In April 2021, the Company settled the majority of its obligations under the plans by providing lump-sum payments of $13.7 million to eligible participants who elected to receive them, and expects to settle the remaining future obligations under the plans through the purchase of annuity contracts from one or more highly rated insurance companies in the second quarter of 2021. We estimate that we will record a total non-cash pre-tax charge associated with the plan termination during the second quarter of 2021 of between $7.5 million and $8.5 million, which primarily represents the acceleration of deferred charges currently accrued in accumulated other comprehensive loss.

The entire disclosure for significant events or transactions that occurred after the balance sheet date through the date the financial statements were issued or the date the financial statements were available to be issued. Examples include: the sale of a capital stock issue, purchase of a business, settlement of litigation, catastrophic loss, significant foreign exchange rate changes, loans to insiders or affiliates, and transactions not in the ordinary course of business.
