When an employee exercises (uses) a nonstatutory stock option (one to which the deferred-taxation
            provisions of the IRC do not apply) under which the employee has an unconditional
            right to receive the stock upon payment of the option price, the difference between
            the fair market value of the stock on the date of exercise and the option price is
            wages.
