Yeah, I know and get that. The point being, that's a serious amount of dosh, and it's no wonder that someone in the chain wants some back! I think the BOD should have negotiated better!! Don't you agree?
So this comes down to career employee mentality. People who would be hired of senior executive positions do not need to work anymore, they've already won and generally can just sail away at any point in time. They do not work because they have to work, but because they chose to work. Boards are responsible for interviewing and sifting through potential candidates until they pick one that they believe will either lead the company towards success or minimize the cost of failure through a very bad time. Those outcomes are not cheap and usually most of their compensation is in some form of stock.
That is why I do not pay attention to any "estimated value" from any media source, I want to know the number of shares and vesting period and if they can't get that then the rest is likely BS. Most executive contracts have an escape clause, otherwise known as a golden parachute, where if the executive has to leave early, then all outstanding shares vest immediately and usually have a kicker bonus attached.
