Investment Policy Statement for a Family Office

Why most investment policy statements fail families

The investment policy statement occupies an awkward position in family office governance. Every credible advisor recommends having one. The majority of single-family offices claim to have one. Yet in practice, a large share of these documents function as little more than a compliance artefact—a PDF filed after a quarterly board meeting and consulted only when an auditor asks for it. According to the 2023 Global Family Office Report published by UBS, fewer than 40% of family offices report conducting a formal IPS review in the preceding 24 months. That figure is striking, given that the same period encompassed one of the sharpest interest rate tightening cycles in four decades, a meaningful repricing of private assets, and a structural shift in the attractiveness of fixed income for the first time since the 2008 financial crisis. An IPS that is not reviewed during such conditions is, functionally, not being used.

The failure mode is almost never technical. Family offices rarely produce IPS documents that omit return objectives or asset allocation ranges. The failure is almost always structural and human: the document conflates risk tolerance with risk capacity, it lacks a dissent protocol, and it contains no mechanism for triggering an unscheduled review when circumstances change materially. What follows is a framework for constructing an IPS that addresses each of these deficiencies with the specificity the task demands.

The seven structural sections of a durable IPS

A family office IPS should be organised into seven distinct sections, each serving a different governance function. Conflating them—as many template-driven documents do—obscures accountability and makes the document difficult to amend incrementally without reopening settled debates.

Section one: purpose, parties, and governing entities

The opening section establishes the legal and relational architecture of the document. It should identify the family office entity (whether a single-family office, a private trust company, or a holding company structure), the principals it serves, the fiduciary standard applicable to the investment team, and the governing law of the IPS itself. For families with structures spanning multiple jurisdictions—a common configuration for ultra-high-net-worth families with operations or residency across the United Kingdom, the United States, Singapore, and the UAE—this section must specify which regulatory framework takes precedence in the event of conflict. It should also name the investment committee members, their roles, and the quorum required to authorise a policy change. This is not boilerplate. A family office that did not name its decision-making quorum in writing discovered during a 2021 estate dispute that two of three principals could not agree on whether a third had voting authority over trust assets. The litigation cost exceeded the disputed investment loss by a factor of six.

Section two: purpose of capital and return objectives

Return objectives must be grounded in a clear articulation of what the capital is for. A family office managing endowment-style capital—intended to sustain a dynasty across three or more generations—operates under fundamentally different return requirements than one managing the proceeds of a recent liquidity event while the founding generation plans significant charitable distributions. The standard framework is to express a net-of-fee, net-of-tax real return target tied to a spending rate and an inflation assumption. A common benchmark is CPI plus 4–5%, derived from an assumed 4% real distribution rate and a 50–100 basis point allowance for fees. However, this figure should be stress-tested against the family's actual spending pattern, tax drag by jurisdiction, and the illiquidity premium required to achieve it. A family with 40% of assets in private equity and venture capital cannot assume the same fee and friction load as one holding a diversified liquid portfolio.

Section three: risk capacity and risk tolerance

This is the section most frequently written poorly, and its weakness ripples through every other part of the document. Risk capacity is an objective, balance-sheet-derived measure: it reflects how much loss a family can sustain before failing to meet non-negotiable obligations—distributions, debt service, lifestyle expenditure, charitable commitments. Risk tolerance, by contrast, is a behavioural and psychological construct: it reflects how much volatility a family's principals can endure without making poor decisions. The two are not the same, and in a downturn they frequently diverge. A family may have the capacity to absorb a 30% drawdown in liquid assets without impairing any obligation, but the psychological tolerance of a second-generation principal who has never experienced a major bear market may be far lower. The IPS should quantify risk capacity using scenario analysis—specifically, a drawdown stress test calibrated to a 2008-style equity decline of approximately 50%, combined with a private asset markdown of 20–30% and a simultaneous liquidity squeeze. Risk tolerance should be documented through structured family interviews conducted by an independent advisor, with results recorded and signed off by each principal. When the two measures diverge, the IPS must specify which takes precedence and under what conditions.

Risk capacity tells you what the balance sheet can absorb. Risk tolerance tells you what the family will actually do under pressure. The IPS must account for both, because markets will eventually test both simultaneously.

Section four: strategic asset allocation ranges

The strategic asset allocation (SAA) section should express policy weights as ranges rather than point estimates, providing the investment team with rebalancing latitude without requiring a full policy review for tactical adjustments. A representative structure might allocate 30–45% to global equities, 15–25% to private equity and venture capital, 10–20% to real assets (including direct real estate and infrastructure), 10–20% to fixed income and cash equivalents, and 5–15% to absolute return and diversifying strategies. These ranges should be tied explicitly to the return objectives in Section Two and stress-tested for feasibility under the risk parameters in Section Three. The SAA should also specify currency exposure limits—particularly relevant for families with liabilities denominated in multiple currencies—and any concentration limits by issuer, sector, or geography.

Section five: liquidity policy and private asset pacing

As private market allocations in single-family offices have grown—from a median of 22% in 2018 to approximately 38% in 2023, according to data from the Campden Wealth Global Family Office Report—the liquidity policy section has become correspondingly more important. It should specify a minimum liquidity reserve expressed as a percentage of annual distributions (a common threshold is 18–24 months of expected distributions held in liquid or near-liquid assets), a vintage-year pacing schedule for private equity commitments, and a protocol for managing capital calls during periods of market stress when public asset values have fallen and the denominator effect has pushed private allocations above their ceiling. The section should also address the family's secondary market policy: under what conditions, if any, may the investment team sell a private fund interest on the secondary market, and at what discount to net asset value does such a sale require investment committee approval.

Section six: ESG policy, exclusion screens, and impact mandates

The integration of environmental, social, and governance considerations into family office portfolios has moved from optional to expected over the past decade, but the IPS treatment of ESG remains inconsistent. Some families treat ESG as a negative screening exercise, excluding tobacco, thermal coal, or controversial weapons in line with documented family values. Others apply a best-in-class integration approach, tilting toward higher-rated issuers within each sector. A smaller number have established formal impact mandates, committing a defined percentage of the portfolio—typically 5–15%—to investments with measurable social or environmental outcomes alongside a financial return. Whatever the family's position, it must be codified with specificity. A statement that the family office will invest in a manner consistent with sustainable development principles is unenforceable and will produce different interpretations from different advisors. The IPS should name the ESG framework adopted (the UN Principles for Responsible Investment, the TCFD recommendations, or a bespoke family framework), list any hard exclusions with the reasoning documented, and specify how ESG compliance is monitored and reported.

Section seven: governance, review cadence, and dissent protocol

The final section is the one most often omitted from template-driven documents, and its absence is the single greatest predictor of IPS irrelevance. A governance section should establish three distinct review triggers. First, a scheduled annual review covering performance attribution, manager assessment, and compliance with the SAA ranges. Second, a triennial strategic review in which the entire IPS—return objectives, risk parameters, and SAA—is reconsidered in light of changes to the family's balance sheet, generational composition, and macroeconomic context. Third, an event-driven review triggered by any material change in family circumstances: a liquidity event above a defined threshold, a death or incapacity of a principal, a change in the tax or regulatory environment in a key jurisdiction, or a sustained breach of any SAA range for more than two consecutive quarters. The section should also specify a dissent and override protocol: which principal or committee member may formally record a dissent from an investment decision, under what conditions a dissent triggers a mandatory pause in execution, and who has the authority to override a veto.

Embedding regulatory and tax architecture into the IPS

Family offices operating across multiple jurisdictions cannot treat the IPS as purely an investment document. The regulatory and tax architecture of the family's structure has direct implications for asset location, manager selection, and reporting obligations, and these must be reflected in the IPS with sufficient specificity to guide decision-making. FATCA and the Common Reporting Standard (CRS) impose information exchange obligations that affect how foreign financial accounts are disclosed, and the entity classification of the family office vehicle—whether it qualifies as an exempt beneficial owner, a passive non-financial entity, or a financial institution under FATCA chapter 4—will determine reporting requirements and influence structuring decisions. BEPS Pillar Two, which introduced a global minimum effective tax rate of 15% for multinational groups with revenues exceeding €750 million, is directly relevant to family offices with operating businesses within the consolidated group. The IPS should document the family's current entity structure, the jurisdictions in which filings are required, and any constraints on asset location or repatriation arising from those obligations. It should also specify the family's policy on AIFMD-compliant fund investments for European-resident principals, noting the marketing passport requirements that apply when accessing non-EU alternative managers.

The IPS is not a portfolio construction manual. It is a constitutional document for the governance of generational wealth, and its durability depends on how precisely it addresses the family's actual legal, tax, and human architecture—not an idealised version of it.

The governance review cadence in practice

The review cadence described in Section Seven functions only if it is institutionalised rather than aspirational. In practice, this means the annual review should be a standing agenda item at the investment committee's year-end meeting, with a standardised reporting package prepared in advance. The package should include performance attribution by asset class and manager, a comparison of actual allocation to SAA ranges, a liquidity stress test using current portfolio positions, and a summary of any regulatory or tax changes in the relevant jurisdictions since the last review. The triennial strategic review warrants an independent facilitation process—typically involving an external advisor who has no management mandate with the family—to ensure that the review does not simply validate existing decisions. This is particularly important when the founding principal is transitioning authority to a second generation, a process that research from Campden Wealth suggests takes an average of 4.7 years to formalise and is characterised by a significant period of overlapping authority during which an unreviewed IPS is particularly vulnerable to being ignored.

Event-driven reviews require a different discipline. The temptation after a major liquidity event is to begin deploying capital before the IPS has been updated to reflect the new balance sheet reality, the changed liquidity profile, and the potentially different tax position. A family that sold a controlling stake in an operating business for £400 million in 2022 and began committing to private equity funds within 90 days, before updating its IPS to reflect the change from illiquid operating assets to liquid financial assets, illustrates the practical cost of sequencing the investment before the governance. The appropriate sequence is to update the IPS first, establish the new SAA and pacing schedule, and then begin deployment within those parameters.

Authorship, ownership, and the living document principle

An IPS written by the investment team alone will reflect the investment team's perspective, which is necessary but not sufficient. The document requires substantive input from the family's legal counsel (on entity structure and fiduciary obligations), its tax advisors (on jurisdiction-specific constraints), and the family council or family office board (on values, exclusions, and generational priorities). The resulting document will be longer and more contested in its drafting than one produced by a single author working from a template. That friction is a feature, not a deficiency. An IPS that emerges from genuine deliberation carries an authority that a template document never can, because every principal who contested a provision and ultimately accepted it has made a commitment to the framework. That commitment is the document's most durable governance asset.
