[1] The aggregate intrinsic value of a stock option in the table above represents the total pre-tax intrinsic value (the amount by which the current market value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders had they exercised their options on December 31, 2012. The intrinsic value varies based on the changes in the market value in the Company's stock. Because the exercise price exceeded the market value of the options, the average intrinsic value was $0 at December 31, 2012.
