Notes to Financial Statements
Derivatives and Fair Value [Text Block]	Note 7 – Purchase of Capped Call Option: In connection with the pricing of the Convertible Notes issued in March 2023, we used $66,211 of the net proceeds from the Convertible Notes to enter into privately negotiated capped call transactions (collectively, the “Capped Call Transactions”) with certain financial institutions. The Capped Call Transactions are generally expected to reduce potential dilution to holders of our common stock upon any conversion of the Convertible Notes and/or offset any cash payments we are required to make in excess of the principal amount of the Convertible Notes upon conversion of the Convertible Notes in the event that the market price per share of our common stock is greater than the strike price of the Capped Call Transactions, with such reduction and/or offset subject to a cap. The Capped Call Transactions have an initial cap price of approximately $120.23 per share, which represents a premium of 120% over the last reported sale price of our common stock of $54.65 per share on March 15, 2023, and is subject to certain adjustments under the terms of the Capped Call Transactions. Collectively, the Capped Call Transactions cover, initially, the number of shares of our common stock underlying the Convertible Notes, subject to anti-dilution adjustments substantially similar to those applicable to the Convertible Notes. The Capped Call Transactions are accounted for as freestanding derivatives and recorded at the initial fair value in Additional paid-in-capital in the Consolidated Balance Sheet with no recorded subsequent change to fair value as long as they meet the criteria for equity classification.
