Nonstatutory Stock Options
A participant generally will not recognize taxable income upon the grant of a nonstatutory stock option. A participant will recognize ordinary income upon the exercise of a nonstatutory stock option equal to the excess of the then fair market value of the stock over the exercise price. The participants basis for determining gain or loss upon the subsequent disposition of such shares acquired upon exercise will be the amount paid for such shares plus any ordinary income recognized as a result of the exercise of the option. Upon disposition, the difference between the sale price and the participants basis in the shares will be treated as a capital gain or loss and generally will be characterized as long-term capital gain or loss if the shares have been held for more than one year upon disposition.
In general, there will be no federal income tax deduction allowed to the Company upon the grant or termination of a nonqualified stock option or a sale or disposition of the shares acquired upon the exercise of a nonqualified stock option. However, upon the exercise of a nonqualified stock option, the Company may be entitled to a deduction for federal income tax purposes equal to the amount of ordinary income that a participant is required to recognize as a result of the exercise, provided that the deduction is not otherwise disallowed under the Code.
