Concentration of Credit Risk [Text Block] | Note 17 - Concentration of Credit Risk: Financial instruments that potentially subject the Company to concentration of credit risk consist principally of cash deposits. Accounts at each institution are insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000. At April 30, 2024 and 2023, the Company had $1,419,000 and $1,569,000, respectively, in excess of the FDIC insured limit. Management has concluded the excess does not represent a material risk, based on the creditworthiness of the counter parties. The Company maintains a deposit account of $305,000 at Flagstar Bank as security for a letter of credit in a similar amount (See Note 15). Signature Bank, previous depository where the $305,000 restricted cash was held, was closed on March 12, 2023 by its state chartering authority and merged with Flagstar Bank. In a joint statement of the U.S. Treasury department, the Federal Reserve, and the Federal Deposit Insurance Corporation, these federal entities confirmed that all depositors of this institution were made whole.
