Please provide a reference. It is customary for the company to purchase Directors and Officers insurance which covers litigation and liability for CEOs and often other executives.
I wasn't aware that was done for all CEOs. You still have to consider the idea that many CEOs have to deal with an array of problems in their personal lives that other people don't have to deal with. I mention that with the caveat that the level of problems other people bring to their personal lives in order to create distractions is cultural.
