Performance Measurement

Performance measurement is more than pulling a number from a brokerage statement. It means aggregating returns across public securities, private funds, direct holdings, real estate, and cash — then presenting those figures in a way that is consistent, comparable over time, and resistant to the temptation to highlight only the wins. For a family office, which may function as the organizational infrastructure around an entire balance sheet, this discipline is foundational.

The mechanics involve choosing a return methodology — such as money-weighted return or time-weighted return — and applying it consistently. Families also typically track performance by sleeve or asset class separately, so they understand which allocations are contributing and which are lagging their benchmark. Attribution analysis goes one step further, breaking down how much of a return came from asset allocation decisions versus individual security or manager selection.

A common confusion is equating reported returns with realized wealth. A three-generation family with significant illiquid holdings may show strong reported returns on paper while facing real constraints on spendable cash — a nuance that only surfaces when performance measurement is integrated with liquidity management. Qualified accountants and investment professionals help families build reporting frameworks that surface these distinctions clearly rather than obscuring them.
