A family with three entities can answer the question of what it owns by reading three sets of accounts. At six or eight, the exercise becomes an assembly job performed annually by whoever is available, and the answer arrives late, in a form nobody trusts, and differs from the answer produced the previous year for reasons that cannot be identified. The shift from per-entity reporting to consolidated reporting is a change in kind rather than in degree.
What makes it difficult is not arithmetic. It is that consolidation requires a series of decisions — what is included, at what value, in what currency, at what date — and that each decision must be applied consistently across entities that were established at different times, in different jurisdictions, under different conventions, by different advisers.
Scope: what is being consolidated
The first decision is which entities and assets are within the report. Wholly owned entities are straightforward. Partial holdings raise the question of whether to include the family’s share or the whole with an offsetting interest. Entities in which the family has influence but not ownership, assets held personally by family members, and vehicles such as foundations that hold assets for the family without the family owning them each require an explicit treatment.
The second is what the report is for, which determines the first. A report intended to show what the family controls includes different things from one intended to show what its members are beneficially entitled to, or what would form part of an estate. Families that do not settle the purpose end up with a report that answers none of these questions cleanly, and members who each read it as answering the one they had in mind.
A consolidated report is only comparable with the last one if the decisions behind it were written down rather than remembered.
Valuation and currency
Assets require a stated valuation basis, and the basis will differ by class. Listed investments are observable. Private holdings, real estate and interests in operating businesses are not, and the family must choose between cost, periodic professional valuation, and a stated methodology applied consistently. Any of these is defensible; changing between them without disclosure is what makes successive reports incomparable.
Currency requires a reporting currency and a stated translation convention: which rate, at which date, for balances as against transactions, and how translation differences are presented. A family holding across four currencies will see movements in the report that reflect exchange rates rather than performance, and unless the report separates the two, it will generate conversations about performance that are actually conversations about the euro.
What it takes to sustain
Consolidation is only as good as the underlying records, and the common failure is attempting it above entities whose bookkeeping is incomplete or maintained on incompatible bases. Where accounting records are kept properly at entity level, from incorporation rather than assembled at year end, consolidation is an exercise in aggregation. Where they are not, it is an exercise in reconstruction repeated annually, and the cost recurs indefinitely.
The decisions themselves should be recorded in a short document that accompanies the report and is revisited only deliberately: what is in scope, on what basis each class is valued, what currency and convention apply, and what date the report is drawn to. That document is what makes this year’s report comparable with last year’s, and it is what allows the work to survive the departure of whoever currently performs it, which over a family’s horizon is a certainty rather than a risk.
