Under its executive stock option plan, National Corporation granted $18$ million options on January $1,2024,$ that permit executives to

purchase $18$ million of the company's $$1$ par common shares within the next six years, but not before December $31,2026($the vesting

date$).$ The exercise price is the market price of the shares on the date of grant, $$15$ per share. The fair value of the options, estimated

by an appropriate option pricing model, is $$2$ per option. Suppose that unexpected turnover during $2025$ caused the forfeiture of $5\%$

of the stock options.
