AUM-Fee Capture
The structural conflict that takes hold when the family’s primary investment advisor is paid as a percentage of assets under management: the compensation model rewards growing AUM, so it quietly works against impact-first deployments, philanthropic distributions, concessionary tranches, and holding appropriate cash.
Also known as: AUM-based capture, percentage-of-AUM conflict, fee-on-assets bias, AUM lock-in.
Context
A family with serious capital almost always meets an advisor before it meets a governance instrument. The first private banker, the first wirehouse team, the first multi-family office, the first OCIO: each one builds a working relationship with the principal years before the family writes a constitution, stands up a council, or hires its own CIO. By the time the office formalizes, the advisor is paid, and the way the advisor is paid is rarely a council decision. It is an inherited contract.
Most of those contracts are ad valorem: a basis-point schedule against assets under management, sometimes tiered, sometimes flat, sometimes overlaid with a performance fee or a fixed retainer. On a $250M balance sheet a 50-bp wrap is $1.25M a year; on $1B it is $5M. Those numbers are large enough to organize a business around. They are also large enough to organize an advisor’s recommendations around. The capture is what happens when the office stops noticing.
The polite literature on advisor selection is mostly written by people whose own compensation runs through the same model, and the language reflects it. “Aligned with growth.” “Skin in the game.” “Aligned interests.” Working principals describe the same model differently, in private. The book uses the working-practitioner term without apology, per policies/style.md §9.
Problem
The conflict is mechanical, not personal. An advisor paid 60 bps on $500M earns $3M a year. Suppose the family moves $80M out of the managed pool: into a private trust company’s directly held positions, into a foundation that pays the foundation’s own program officers, into a recoverable-grant sleeve at a DAF, into a $50M catalytic first-loss tranche the advisor doesn’t custody, into an operating-company reinvestment that the advisor’s platform can’t book. The advisor’s revenue drops by roughly $480K a year. The family hasn’t asked whether that drop is appropriate; the advisor’s recommendations have been quietly shaped by it for years.
The compounding harm is that the affected recommendations are exactly the ones a serious impact-first office most needs. Concessionary tranches leave the platform. Direct investments leave the platform. Patient-capital allocations leave the platform. Recoverable-grant DAF strategies leave the platform. Operating-company concentrations the advisor sees as “trapped capital” leave the platform. The advisor doesn’t oppose them (opposition would surface the conflict), but they don’t appear in the meeting deck, and the manager-selection process drifts toward liquid public-market sleeves the platform can hold.
The principal who asks “why does our impact allocation keep coming back at single-digit percentages?” is rarely told the structural answer.
Forces
- The fee model came first. Family-side governance arrives years after the advisor relationship. A clean-sheet decision about advisor compensation almost never happens; the office is renegotiating a contract rather than designing one.
- AUM-fee disclosure is technically clear and operationally invisible. Every Form ADV, every wrap agreement, every OCIO contract states the basis-point schedule. Disclosure isn’t the question. What gets buried is the cumulative dollar figure across custodians and the structural recommendation pattern the figure shapes.
- Recommendations against the fee model are uncomfortable to make. An advisor who proposes a structure that reduces their own revenue is rare. An advisor who proposes it visibly, on a published memo the council reviews, is rarer still.
- The principal often likes the advisor. Long relationships, college roommates, trustee-of-the-foundation overlaps. The capture compounds because raising the question feels like an accusation of one person rather than a critique of a fee model.
- The MFO industry runs on this model. Most U.S. multi-family offices are structured as registered investment advisers paid on AUM. Asking for a flat-fee or retainer arrangement is asking the firm to depart from its core operating model, and many firms can’t accommodate it without restructuring the engagement.
- Performance-fee overlays don’t solve it. A 10% performance fee above a benchmark on a public-equity sleeve keeps the AUM base intact and adds a separate incentive on volatility. It changes the conflict; it doesn’t remove it.
Resolution
Treat advisor compensation as a council-level governance decision and revisit it on a published cadence.
The fixes are structural, not interpersonal. Five moves, in order, take the capture from invisible to managed:
-
Surface the dollar number. The consolidated reporting layer at the family’s single source of truth should produce an annual fee-attribution view: every basis point paid to every advisor, custodian, manager, platform, and overlay, denominated in dollars against the full balance sheet. The first time most offices run this report the figure is 15–40% larger than the principal expected, because per-custodian footers had been read individually. Without this number, every later move is a negotiation in the dark.
-
Separate the roles. Advisor of record (the holistic counselor who looks at the whole family and writes the IPS) and discretionary manager (the entity that buys and sells securities under the IPS) can be the same firm or different firms. When they’re the same firm and paid on AUM, the conflict is structural. Separating them, even when the discretionary manager is still the same firm under a different fee schedule, restores the advisor-of-record’s ability to recommend against the discretionary manager’s product shelf without losing personal revenue.
-
Pick a fee model that fits the work. Three working alternatives, with the basis on which each is appropriate:
Fee model What it pays for When it fits Fixed retainer The advisory function as a service: IPS drafting, manager diligence, council reporting, philanthropic strategy. Quoted in dollars per year, typically $250K–$1.5M depending on scope. When the office wants advisory independent of where assets sit, with the freedom to move capital out of the platform without renegotiating advice. Flat basis points on the managed book only Discretionary management of a defined sleeve, with the advisor explicitly disclaiming an opinion on the unmanaged book. When the family wants the convenience of bundled custody-and-management on a slice (commonly the public-equity sleeve) and a separate retainer for everything else. Hybrid: retainer + sliding-scale AUM with explicit zero band Retainer covers the advisory function; AUM fee starts only above a stated threshold (e.g., zero fee on the first $200M, 25 bps above) and excludes named carve-outs (PRIs, MRIs, direct investments, philanthropic vehicles). When the office wants a single advisor relationship but with the philanthropic, concessionary, and direct slices explicitly outside the fee base so they don’t become the rebalancing variable. A pure AUM-fee schedule with no retainer component is the default in the industry and is almost never the right fit for an impact-first family office.
-
Carve impact-first capital out of the fee base. Recoverable grants, PRIs, MRIs at concessionary terms, first-loss tranches, direct operating-company holdings, and DAF principal balances should be excluded from any AUM-fee calculation by contract. Otherwise the office is paying its advisor 50 bps a year on capital the office is deliberately deploying at lower expected return. The arithmetic is intolerable once it’s written down.
-
Independent fiduciary review on a published cadence. An outside fee-only consultant with no platform to sell reviews the advisor relationship every two or three years. The deliverable is a one-page memo to the investment committee: total fees paid, structural conflicts identified, fee-model alternatives priced. The cost is low (typically $25K–$75K). The deliverable, once it exists, makes the renewal conversation possible because the committee is reading an outside reading of its own contract.
The fee-model conversation is genuinely contested. Some practitioners argue that AUM-aligned compensation produces better long-horizon stewardship because the advisor and the family rise and fall together; others argue that the alignment is a marketing frame for a structural conflict the family is paying for twice (once in the fee, once in the recommendations the fee shapes). The book takes the second position because the working-practitioner consensus in family-office operator conversation, at FOX, Campden, Toniic, and Mission Investors Exchange, is that AUM-fee capture is the most-named conflict the published advisor literature refuses to name.
How It Plays Out
A third-generation principal at $720M of investable wealth runs a six-year-old SFO with an in-house controller and a chief-of-staff. The investment function has always been outsourced to a regional OCIO the family hired in year two, paid on a tiered AUM schedule that effective-rates to 38 bps across the office’s full managed pool. The family also pays the founding generation’s long-tenured wirehouse team 65 bps on a $90M legacy trust account the principal “doesn’t want to disturb,” and a $40M alternatives platform charges 50 bps on top of the underlying fund-of-fund fees. Year-five fee attribution had never been run; year six is the first year the family’s new single source of truth produces it.
The report runs to one page:
| Relationship | Mandate | Asset base | Fee schedule | 2025 fee paid |
|---|---|---|---|---|
| Regional OCIO | Discretionary management, public + private | $510M | Tiered: 50 bps to $250M, 30 bps to $500M, 20 bps above | $1.94M |
| Wirehouse legacy team | Legacy trust account, discretionary | $90M | 65 bps wrap | $585K |
| Alternatives platform | Fund-of-fund overlay | $40M | 50 bps platform fee (above underlying) | $200K |
| Foundation portfolio sleeve | OCIO sub-mandate at foundation | $80M (foundation) | 30 bps | $240K |
| Total advisor and platform fees | $720M consolidated | Blended ~41 bps | $2.96M |
The principal had assumed the all-in number was around $2.1M. The $860K gap is the wirehouse wrap, the alternatives-platform overlay, and the foundation sleeve, each of which had been read on its own custodian statement and had never been summed.
The structural finding is sharper. The OCIO’s tiered schedule charges 30 bps on a $50M PRI to a workforce-mobility fund that the OCIO doesn’t custody (the PRI sits at the foundation, but the OCIO’s contract sweeps the foundation’s invested corpus into the AUM base), and 30 bps on a $35M MRI commitment to a regional climate fund. The OCIO had recommended a smaller MRI commitment than the rising-generation council had wanted; the staff memo’s stated reason was “manager capacity,” but the structural reason (visible only once the fee number is on one page) was that a larger MRI commitment would have replaced the OCIO’s preferred climate-tilt SMA, which had been earning 50 bps in the same allocation slot.
The council reshapes the engagement over the following nine months. The OCIO contract is restructured to a $750K fixed retainer plus a flat 22 bps on the discretionary managed sleeve, with PRIs, MRIs, direct operating-company holdings, and the foundation’s programmatic vehicles excluded from the fee base by named carve-out. The wirehouse legacy trust account is transitioned to a fee-only custody arrangement at a different custodian; the relationship with the original advisor is preserved as a non-discretionary one and re-priced at a $40K annual retainer. The alternatives platform is repapered to a flat-dollar quarterly fee against the look-through fund value rather than a basis-point overlay. An independent fee-only consultant produces a one-page review for the investment committee the following spring.
Year-seven fee attribution comes in at $1.62M against the same $720M base, a blended 22 bps, with $40M of carved-out impact-first capital outside the fee base entirely. The $1.34M annual savings doesn’t drive the decision; the unblocked recommendation pattern does. By year eight the office’s MRI commitment has scaled from $35M to $96M, three direct co-investments have closed without the OCIO’s product shelf as a filter, and the foundation’s recoverable-grant sleeve has grown from $4M to $14M. The advisor relationship has improved, not deteriorated, because the conversation is no longer downstream of a structural conflict no one wanted to name.
A failure case looks familiar. A $1.1B office hires a brand-name multi-family office in year one, accepts the standard 45 bps blended wrap, and never restructures it. The MFO is competent; the principal is loyal; the rising generation gets along with the relationship partner. Across twelve years the family pays roughly $59M in advisory fees against an impact-first allocation that never crosses 6% of the balance sheet, against a value-aligned allocation that drifts toward whatever liquid product the MFO’s platform happens to be marketing that year, and against an MRI commitment that the rising-generation council has been asking for since year four and that the staff memo keeps deferring “to the next strategic review.” Nothing is wrong. Everything is wrong.
Consequences
The harm is structural rather than dramatic. The capture rarely produces a single bad allocation; it produces a slow, persistent tilt in every allocation conversation. Impact-first capital stays smaller than the council wants. Direct investments don’t get sourced. Concessionary tranches don’t get modeled. Operating-company concentrations don’t get harvested. The advisor’s quarterly deck reports against a benchmark that the advisor and the family chose together, and against that benchmark the office is performing fine.
The repair is uncomfortable on first delivery and powerful on the second pass. The first conversation with a long-tenured advisor about a fee restructure is harder than any other governance talk in the office’s first decade. It is the one in which the family has to ask, in writing, whether the advisor’s recommendations have been shaped by the advisor’s pay. Most advisors handle the question well once it’s on the table. A few don’t. The ones who don’t are revealing exactly the conflict the question was meant to surface.
The cost of repair is small relative to the cost of inaction. An independent fee-only review is $25K–$75K. A retainer-plus-carve-out restructuring is the work of a single negotiation cycle. The IPS amendments are a council session. The single source of truth’s fee-attribution module is a few hours of configuration once the platform is in place. Against $1M–$5M of annual fees on a family-office balance sheet, the work earns its keep in one cycle and continues earning for decades.
The deeper consequence sits at the field level. As long as the wealth-management trade press is funded by advertising from the firms that run the capture, the published literature will continue to soft-pedal the conflict, and working principals will continue to discover it on their own, usually around year five of office operation, usually after a rising-generation member asks a question the staff memo can’t answer. The book takes the position that naming the capture in plain language, with the dollar arithmetic and the structural fixes, is one of the most consequential things a reference for principals can do.
