Earnings Per Share [Text Block]	NOTE 4 EARNINGS (LOSS) PER SHARE Basic income (loss) per share is computed by dividing our net income (loss) by the weighted average number of shares of our Common Stock outstanding during the period. Shares of Common Stock outstanding under the share lending arrangement entered into in conjunction with the 2025 Notes (as defined in Note 7) are excluded from the calculation of basic and diluted earnings per share because the borrower of the shares is required under the share lending arrangement to refund any dividends paid on the shares lent. Refer to Note 7. For diluted earnings per share, the dilutive impact of stock options and warrants is determined by applying the “treasury stock” method. The dilutive impact of the 2029 Convertible Notes, 2033 Senior Notes, the 2023 Convertible Notes and the 2025 Notes (each, as defined and discussed in Note 7) has been considered using the “if converted” method. For periods in which their effect would have been antidilutive, no effect is given in the dilutive computation to Common Stock issuable under outstanding options or warrants or the potentially dilutive shares issuable pursuant to the 2029 Convertible Notes, 2033 Senior Notes, the 2023 Convertible Notes and the 2025 Notes. A total of 294,774,975 and 82,817,175 potential shares of Common Stock were excluded from the calculation of diluted net loss per share for the three months ended June 30, 2024 and 2023, respectively, because their inclusion would have been antidilutive. A total of 293,731,532 and 82,438,648 potential shares of Common Stock were excluded from the calculation of diluted net loss per share for the six months ended June 30, 2024 and 2023, respectively, because their inclusion would have been antidilutive. A full presentation of diluted earnings per share has not been provided because the required adjustments to the numerator and denominator resulted in diluted earnings per share equivalent to basic earnings per share. During the three months ended June 30, 2024, no options were exercised and 549,687 restricted stock units vested, resulting in the issuance of 384,378 shares of Common Stock. During the six months ended June 30, 2024, no options were exercised and 549,687 restricted stock units vested, resulting in the issuance of 384,378 shares of Common Stock. During the three months ended June 30, 2023, no options were exercised and 549,680 restricted stock units vested, resulting in the issuance of 386,971 shares of Common Stock. During the six months ended June 30, 2023, no options were exercised and 549,680 restricted stock units vested, resulting in the issuance of 386,971 shares of Common Stock.
