A private club board is made up of accomplished people who are volunteers here, meeting monthly, carrying fiduciary responsibility for an operation most of them do not work inside. Their entire view of the club's financial health arrives in a packet a few days before the meeting.
When that packet is comprehensive but unreadable, governance degrades in a predictable way: the board debates the items it can understand, defers the ones it cannot, and depends on whichever member happens to be most financially fluent. The fix is rarely more reporting. It is better-shaped reporting, arriving on a reliable cadence, with someone accountable for the narrative.
