(1)Represents the weighted average contractual remaining life in years. (2)Aggregate intrinsic value represents the total pretax intrinsic value (i.e., the difference between the Company’s stock price at year end and the option exercise price, multiplied by the number of shares) that would have been received by the option holders if they had exercised their options on the last day of the year. Options with exercise prices above the year end stock price are excluded from the calculation of intrinsic value. The intrinsic value will change based on the fair market value of the Company’s stock.
