Problem 19-1 (Algo) Stock options; forfeiture; exercise [LO19-2]

On October 15, 2023, the board of directors of Martinez Materials Corporation approved a stock option plan for key executives. On January 1, 2024, 25 million stock options were granted, exercisable for 25 million shares of Martinez's $1 par common stock.

• The options are exercisable between January 1, 2027, and December 31, 2029, at 90% of the quoted market price on January 1, 2024, which was $20.
• The fair value of the 25 million options, estimated by an appropriate option pricing model, is $6 per option.
• Martinez chooses the option to recognize forfeitures only when they occur.
• Ten percent (2.5 million) of the options were forfeited when an executive resigned in 2025.
• All other options were exercised on July 12, 2028, when the stocks price jumped unexpectedly to $24 per share.
