Writing a rebalancing policy for a billionaire family office
Built on Chapter 9 of The Single Family Office by Richard C. Wilson. Full chapter text: FamilyOffices.com.
A rebalancing policy should explain when the investment team must review an exposure and what authority it has to change it. A target allocation by itself leaves staff uncertain about what to do when markets or family obligations move the portfolio away from the plan.
Chapter 9 emphasizes the family's particular needs and investment approach. I would apply that principle by writing rebalancing instructions suited to the actual holdings. Liquid securities and long-held private assets cannot always be adjusted in the same way.
Define the portfolio the policy covers
Identify the assets under the investment team's authority. Distinguish managed liquid holdings from retained businesses and other assets the family has chosen to hold separately. The policy should explain how those exposures inform decisions without implying that the team can sell them.
Use consistent valuation information when comparing actual and intended allocations. State the limits of delayed private-asset values. An apparent change in allocation can partly reflect different reporting schedules.
Keep entity restrictions visible. A consolidated target may require different implementation steps for each owner. Confirm the available authority and any necessary consents before treating a proposed adjustment as routine.
Establish a review trigger
The responsible investment professionals should propose a review process suited to the mandate. It may consider changes in exposure, scheduled assessments, or material family events. The office should understand what starts the review and who performs it.
Distinguish a review trigger from an automatic trade. The team may need to assess costs, liquidity, and other consequences before acting. Have qualified professionals address those issues for the actual holdings.
State how the committee learns about an exposure outside the approved range. A limit without a reporting route can remain breached while everyone assumes another employee is handling it.
Consider the available sources of adjustment
New cash and expected withdrawals may affect exposure without requiring a sale. The team should examine the feasible methods within the approved policy. Explain the consequences of each method before choosing one.
Private commitments need separate attention. An unfunded commitment or delayed exit can affect future exposure even when the current funded amount looks modest. Include that information in the review.
Avoid pretending that an illiquid holding can be reduced quickly at its reported value. If a sale is possible, assess the actual terms and implications. The family should see the difference between a desired allocation and an executable adjustment.
Give staff an implementable delegation
State which changes the investment team can make and which require committee or owner approval. If delegated authority depends on conditions, describe who confirms them. Employees need to know when to stop and escalate.
Identify the record required after action. The team should explain the reason, the policy basis, and the resulting exposure. This lets the committee oversee implementation without approving every ordinary adjustment.
Set a route for unusual circumstances. An urgent market development or unexpected family payment may require a decision outside the normal schedule. Use the established delegation and escalation process.
Treat exceptions as decisions
A family may deliberately retain a concentrated position. Record the reason and the implications for the rest of the portfolio. That decision should be visible when the team is evaluated against its mandate.
Give an exception a review condition. The relevant question may be whether a business event has occurred or a family objective has changed. A date alone does not necessarily explain when the underlying judgment should be reconsidered.
If exceptions become routine, review the policy itself. The office should maintain instructions that reflect the choices the authorized decision makers actually want implemented.
Check the instructions with a recent portfolio change
Take an actual change in exposure and follow the proposed process. Identify the trigger, available information, and approval route. Ask the team to explain the feasible implementation and reporting steps.
Fix any point where employees must guess. The final policy should let them recognize when action is needed, establish what they may do, and provide the committee with a factual record afterward.
What to take from this
- Define the covered assets and review triggers.
- Match delegation to feasible implementation.
- Record deliberate concentration as an authorized choice.

Questions and answers
Must every trigger cause an immediate sale? The policy should distinguish a required review from a specific implementation instruction.
Can private holdings use the same process as liquid securities? Their terms and access constraints need separate treatment within the overall plan.
