None of the options will be exercisable before November 19, 2022. All options which have not vested as of November 18, 2031 will be canceled. On the grant date, the options were valued using a Monte Carlo Simulation approach. A Monte Carlo Simulation is a statistical technique that is used to model probabilistic systems and establish the probabilities for a variety of outcomes. However, because attainment of the performance condition cannot be considered probable, no compensation cost was recognized relating to these options as of September 30, 2023. Management will re-assess the probability of achieving the performance condition at each reporting date. At September 30, 2023, the Company has collectively authorized the issuance of 15,787,200 options to purchase shares of common stock under its Non-Qualified Stock Option Plans. Options typically vest over a three-year period and expire no later than ten years after the grant date.
