A third-generation family office serves 47 family members across 14 branches. The founding patriarch wanted capital preservation. His grandchildren want impact investing. A 52-year-old branch funds three startups. A 19-year-old branch needs tuition next year. There is no single investor. There is a federation of goals, each with its own horizon, risk tolerance, and tax profile. The endowment model cannot answer who the portfolio is for.
A family office manages the capital and financial affairs of wealthy families. The curriculum draws one structural distinction.
- Single-family office (SFO). Management is dedicated to a single individual or family. Running one costs approximately 60 basis points of assets under management (AUM) per year.
- Multi-family office (MFO). Serves several families to share operating expenses and back-office administration, or to pool investment ideas.
An MFO usually starts as an SFO and later invites other families to join. The source of capital varies. In some cases it is spun off from an operating company (for example, Mark Zuckerberg of Facebook).
Common mistakes
- Inventing family-office categories. The curriculum distinguishes only single-family and multi-family offices. An MFO pools a small number of UHNW families over $30-50 million, and an SFO costs about 60 bps of AUM per year. Do not add "virtual" or "embedded" types or a $100M threshold.
- Missing the outside-clients trigger. Accepting nonfamily capital can require SEC registration, with compliance, equal-treatment, and reporting burdens that more than double operating costs. Soros shut down; Rockefeller & Co. registered.
- Ignoring concentration in first-generation wealth. Concentrated stock needs a completion portfolio of low-correlation assets, options collars, scheduled post-earnings sales, or stock-collateralized loans, not just generic diversification.
Bottom line
- Family offices are single-family or multi-family: an SFO serves one family (about 60 bps of AUM per year), and an MFO pools UHNW families holding over $30-50 million to share costs
- Generation drives allocation: first-generation new money preserves concentrated wealth, second-generation and beyond old money grows wealth with an after-tax, long-term-gain orientation
- Taxes are the dominant constraint: Section 1256 contracts blend 60% long-term and 40% short-term treatment, cutting a 40% effective rate to 28%
- Goals-based investing (Chhabra) splits wealth into personal, market, and aspirational buckets matched to personal, market, and idiosyncratic risk
Exam shortcut
Identify the structure as SFO or MFO. Do not reach for fabricated categories. The SFO costs about 60 bps of AUM per year; the MFO pools a small number of UHNW families over $30-50 million. Watch for the outside-clients trigger. Any scenario mentioning nonfamily capital is about SEC registration, equal treatment, and doubled operating costs. The family-member definition is direct bloodline plus spouses, up to 10 generations. Match the generation.
