Notes to Financial Statements
Subsequent Events [Text Block]	17. Subsequent Events: On October 26, 2022, our Board of Directors approved the action to make our Energy business available for immediate sale. On October 28, 2022, we entered into a stock purchase agreement to sell our Energy business to Veritas Capital, a leading technology and government investment firm, for a potential aggregate consideration of $3,300 million, including cash consideration of $3,100 million to be paid at closing and up to $200 million of additional contingent cash consideration based on Veritas Capital’s future return on its investment. This transaction is expected to close in the first quarter of 2023 and subject to customary closing conditions, including regulatory approvals and working capital adjustments. We do not expect to have any continuing involvement in the Energy business subsequent to closing.

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.
