Poon, the 100 mill is just what GD plans to get in the next five years. Try 500 million in total for all of them. There are 36 managers who will take 4.6 % of APA, so that is also not counting any profits they will get when they flog Jetstar off and return QF to the ASX.
Considering that they are paying 11.6 Billion now, and they are looking at a 20% profit, you can work out what that comes to, and why the stakes are so high. They will spend anything to keep pilots segregated.
