How many years worth of that compensation is your boss willing to put into an escrow account, payable to you in full the day that job ceases to exist? $300k sounds great, until the airplane is sold. If they are asking for your commitment, then it’s only fair to ask the same of them.

Corporate gigs are usually just 1 death or divorce away from going away (or one new CEO, just ask GE’s flight Department). SWAs stability is something you could take to the bank.
