My personal (anecdotal) experience with directors is that most boards seems to be comprised in a manner similar to the following example:
- Chairman of the Board (usually either the current or former CEO of A Corp.)
- Several other C-level executives and a few VPs from A Corp.
- "Independent" directors who are executives at B, C, and D Corps., where the CEO of A Corp. is also an "independent" director
- Enough additional independent directors to meet independence and expertise requirements
