Notes to Financial Statements
Subsequent Events [Text Block]	Note 6. Subsequent Events All of the effects of subsequent events that provide additional evidence about conditions that existed at the balance sheet date, including the estimates inherent in the process of preparing the consolidated financial statements, are recognized in the consolidated financial statements. The Company does not recognize subsequent events that provide evidence about conditions that did not exist at the balance sheet date but arose after, but before the consolidated financial statements are issued. In some cases, unrecognized subsequent events are disclosed to keep the consolidated financial statements from being misleading. The Company has evaluated subsequent events through May 11, 2022, the date on which the consolidated financial statements were issued.

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.
