The aggregate intrinsic value in the table above represents the total intrinsic value that would have been received by the option holders had all option holders exercised their options on December 31, 2013. This amount is changed based on the market value of the Company's ordinary shares. Total intrinsic value of options exercised during the years ended December 31, 2011, 2012 and 2013 was $ 2,197, $ 572 and $ 1,741, respectively. As of December 31, 2013, there was $ 423 of unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Plans. This cost is expected to be recognized over a period of approximately three years. The following table represents the employee option activity whose vesting is contingent upon meeting various departmental and Company's wide performance goals (including revenue growth and net gain index), as of December 31, 2013. These options have been included in the above table on employee option activity: | Number of options | | Weighted average exercise price | | Weighted average remaining contractual term (in years) | | Aggregate intrinsic value | | | | | | | | | | | | | | | Outstanding at January 1, 2013 | | 139,250 | | $ | 1.44 | | | 5.55 | | $ | 454 | | | | | | | | | | | | | | | Outstanding at December 31, 2013 | | - | | $ | - | | | - | | $ | - | | | | | | | | | | | | | | | Exercisable at December 31, 2013 | | - | | $ | - | | | - | | $ | - | | | | | | | | | | | | | | | Vested and expected to vest at December 31, 2013 | | - | | $ | - | | | - | | $ | - | | During 2007 and 2008, the Company granted certain executives and other key employees, options to purchase 825,000 ordinary shares and 100,000 ordinary shares, respectively, with vesting contingent upon meeting various departmental and Company-wide performance goals, including revenue growth and net gain index. The options have an exercise price equal to the fair market value of the Company's ordinary shares on the date of grant, contingently vest over a period of four years, and are for a term of ten years. The fair value of those options was estimated on the date of grant using the same option valuation model used for the other options granted. If such goals are not met, no compensation cost is recognized and any recognized compensation cost is reversed. The inputs for expected volatility, expected dividends, expected term and risk-free rate used in estimating those options' fair value are the same as those noted in the table related to options issued under the Plans.
