What the guides say
The IFC Family Business Governance Handbook says a family assembly, also called a family forum, is a formal discussion forum for family members. It says assemblies are usually held about once or twice a year, and lists the issues they handle: approving changes to family values and vision, educating members about rights and responsibilities, approving family employment and compensation policies, and electing the members of a family council or other committees.
The IFC also says assemblies avoid conflict from unequal access to information and that they are open to all family members as a general rule, though some families set age limits or rules for in-laws. Once a family passes about 30 members, it describes electing a smaller family council to do the working governance.
What the Rockefellers say they do
CNBC quotes David Rockefeller Jr.: "We meet as a family twice a year, often more than 100 of us in a same room." He called the family forum the first of four pillars, said members are invited at 21, and described discussing direction, projects, new members and milestones. Momentum Advisory Group adds that the family has an informal non-solicitation rule.
The video says the Rockefellers built exactly this kind of governance and that it is why the fortune lasted.* The sources describe the meetings and values, but they do not establish that governance alone caused the result. The Vanderbilts, the video says, had nothing like it.* We found no source for that. The Times reported that the Vanderbilts held a reunion in 1973, which shows a gathering, not a governance structure.
The video's three items, compared with the guides
The video lists: the money, all of it on the table in front of every adult; the rules, such as who can ask for capital and what happens if someone breaks them; and the next generation, who is ready and what they need to learn.* The first is not described in the guides we read, which talk about keeping members informed about business issues, not about full disclosure of every account. The second and third line up with the IFC list of policies and education.
So the three items are a reasonable summary of themes, not a documented agenda. The exact content depends on the family, its size and whether there is an operating business.
Worked example: a two-hour first meeting
Suppose a family of 12 adults wants a first meeting. One layout that follows the IFC themes: 20 minutes on the family's values and what it wants the money to do, 30 minutes on rules (who can ask for capital, how, and what happens next), 30 minutes on how the next generation learns about money, 20 minutes on one decision to make that day, and 20 minutes to agree the date and chair for the next one.
With 12 adults it is far below the 30-member point at which the IFC describes a council, so the whole group can meet. This is an illustration of how to organize the time, not a template used by any particular family.
Common questions
How often should it meet? The IFC says about once or twice a year. The Rockefellers say twice. Some families meet more often when a business or a transition is under way.
Does everyone see all the money? Not necessarily. The IFC describes informing members about business issues. Families set their own rules about financial detail.
Is the three-generation rule true?* See our page on the Vanderbilt fortune for what the sources do and do not support.
What about lending between members? See how a family bank works.
Asterisk notes
*The video's claims that most families lose their money within three generations, that the Rockefeller governance is why the fortune lasted, and that the Vanderbilts had nothing like it are retained from the video. The exact agenda of a private family meeting is not public, and the three-item list is a simplification.
