A board pack is written for a named group of people who have a legal duty to the company, which is exactly why it says things nothing else you produce says.
Real numbers rather than presented ones. Risks named as risks. Legal exposure. Decisions about people, sometimes about people who report to the person printing it. The going concern discussion. The acquisition you are considering and the one you walked away from.
It is the single document that would do most damage in the wrong hands, and it is distributed by email on a monthly schedule.
