Where else this board sits

Other services 3Professional services 1

The sectors these directors govern in elsewhere. This company, and any charity it is the legal face of, are excluded - counting them would just tell you what you are already looking at.

Gaps to watch

  • Several long-serving directors could step down together
  • Narrow spread of sectors across the board

Where to look Suggested search: succession planning for long-tenured seats; directors from a wider range of sectors.
