On January 1, 2019, Ayayai Corporation granted 9.100 options to key executives. Each option allows the executive to purchase one share of Ayayal's $5 par value common stock at a price of $21 per share. The options were exercisable within a 2-year period beginning January 1, 2021, if the grantee is still employed by the company at the time of the exercise. On the grant date, Ayayai's stock was trading at $26 per share, and a fair value option-pricing model determines total compensation to be $402,000. On May 1, 2021, 7.280 options were exercised when the market price of Ayayal's stock was $30 per share. The remaining options lapsed in 2023 because executives decided not to exercise their options.
