This excerpt taken from the ATVI 10-Q filed Nov 3, 2005.
Aggregate Earned Value shall mean the aggregate of the value of Restricted Shares vested by you prior to termination and the value of the stock options you may have exercised, if any, prior to termination. Accordingly, Aggregate Earned Value shall be determined by adding two components:
(i) The value of Restricted Shares obtained by multiplying the number of Restricted Shares you may have vested as of the termination date, whether then sold or unsold, by the Market Price of Restricted Shares on the date of their respective vesting; and
(ii) The value of exercised stock options, which shall be equal to the net, pre tax proceeds actually realized by you from the exercise of any stock options prior to termination and sale of shares issued upon such exercise. In the event you exercise a stock option but do not sell and still hold the shares issued upon such exercise as of the termination date, the proceeds realized by you with respect to those shares shall be deemed to be the remainder obtained by subtracting (i) the total price paid upon exercise of the option for such shares from (ii) the Market Price.
