Benchmarking returns in a billionaire family office
Built on Chapter 9 of The Single Family Office by Richard C. Wilson. Full chapter text: FamilyOffices.com.
Agree on the comparison before evaluating the result. A family office can make an ordinary portfolio look exceptional by changing the measure after performance arrives. A billionaire family needs a consistent method tied to the work it actually assigned.
Chapter 9 introduces the family's investment approach, and Chapter 10 warns about inconsistent performance measurement. I would connect those principles by documenting the benchmark and reporting basis at the start of the mandate.
Match the comparison to the assignment
Identify the assets and responsibilities being evaluated. A liquid manager should not be judged as if they controlled the retained family business. A portfolio holding reserves for known obligations has a different assignment from capital committed for long periods.
Ask the investment professionals to explain why the proposed comparison fits. The family should understand the relevant exposure and constraints. A familiar market index may be useful for one purpose and incomplete for another.
Keep owner objectives visible alongside the comparison. A benchmark result can show how implementation performed, while cash availability shows whether the portfolio served a required obligation. Both questions deserve a clear answer.
Establish a common reporting basis
State the periods covered and whether costs are included. Explain how contributions and withdrawals affect the calculation. The method should be suitable for the mandate and applied consistently.
Keep the source of the figures identifiable. The office should know whether a manager supplied them, an administrator calculated them, or internal staff reconciled them. A polished presentation does not establish the basis of a number.
Avoid combining incompatible figures without explanation. Private-asset estimates and current market prices may reflect different information dates. Preserve those limitations in the report.
Separate cash results from changes in value
Report distributions and remaining value distinctly where relevant. A private investment's estimated gain is different from cash returned to the family. Owners should know which result can support current payments.
Explain how valuation changes affect the reported return. The office may need qualified assistance to assess the methodology. It should not accept an estimate merely because the resulting performance appears attractive.
Use comparable information when considering alternatives. A gross record for one manager and an after-cost record for another can lead to a misleading decision. Identify the differences before ranking them.
Keep the method stable through disappointing periods
A measurement change may be justified when the mandate changes or an error is discovered. Document the reason and explain its effect. Preserve the earlier basis where useful for comparison.
Do not let compensation incentives quietly determine which measure appears in the report. The people overseeing the investment team should understand how reported performance connects to any rewards.
Ask for an explanation of a shortfall using the agreed method. Distinguish a deliberate portfolio choice from an implementation problem. The family needs evidence of what happened before deciding whether to change the mandate or the manager.
Recognize limits in comparisons
A peer portfolio may have different liquidity and concentration. Explain those differences before drawing conclusions. The family can learn from the comparison without assuming the other portfolio was available on the same terms.
Short histories and incomplete records deserve explicit treatment. The office should avoid a precise ranking that the evidence cannot support. Acknowledging a limitation is more useful than hiding it behind a complicated table.
Keep the number of reported measures manageable. Give the main assignment the clearest view and use supporting measures to answer distinct questions. A large appendix should not obscure the result the committee is responsible for assessing.
Make the report useful for a decision
Connect performance findings to the next oversight action. The committee may request more evidence, review a mandate, or continue monitoring on the existing basis. State the reason and assign the work.
Ask a family representative to explain the report in ordinary language. If they cannot tell what was earned, what remains estimated, and how the result compares with the agreed assignment, simplify the presentation while keeping its limitations visible.
What to take from this
- Agree on the comparison and calculation basis first.
- Distinguish estimated value from returned cash.
- Explain changes in measurement openly.
