Investment Policy Statement for Family Offices (2024)

Why most investment policy statements fail families

The investment policy statement is, in theory, the foundational governance document of any serious investment programme. In practice, a significant share of family office IPS documents are outdated, under-specified, or treated as compliance formalities rather than living governance instruments. A 2023 survey by the Global Family Office Report (Campden Research) found that fewer than 40% of single-family offices reviewed their IPS on an annual basis, and roughly 22% had not formally amended their document in more than five years. For an asset class mix that routinely includes private equity, direct real estate, hedge fund allocations, and cross-border structures, a five-year-old IPS is, functionally, an obsolete one.

The consequences are not merely administrative. When markets dislocate — as they did in Q4 2018, March 2020, and again during the 2022 rate shock — investment committees without a clear, current IPS default to improvised decision-making. Liquidity gets drawn down in ways that conflict with long-term objectives. Mandate drift occurs quietly. Accountability becomes diffuse. A properly constructed IPS prevents none of these risks entirely, but it provides the institutional memory and decision framework that makes coherent governance possible even under duress.

The six structural sections of a durable IPS

Structuring an IPS for a family office differs materially from the institutional pension fund templates on which many advisors mistakenly model their work. Family offices carry unique considerations: multigenerational beneficiary structures, illiquid direct investment portfolios, concentrated legacy positions, embedded philanthropic mandates, and often, the preferences of a founding principal who sits both as beneficiary and decision-maker. The document must accommodate all of these without becoming unnavigable.

Section one: purpose, scope, and legal entity mapping

The opening section should define precisely which assets and entities fall under the IPS's authority. For a family office managing assets across, say, a Cayman Islands exempted fund, a Luxembourg RAIF, a UK trust, and a directly held property portfolio, the IPS must specify whether all four are governed by this single document or whether subsidiary mandates exist for each vehicle. Ambiguity here creates real problems during external audits and when new family members or professional trustees join the governance structure. The section should also state the document's governing law — particularly relevant for families with assets in MiFID II-regulated jurisdictions, where investment policy documentation intersects with suitability obligations under Article 25 of the Directive.

Section two: governance authority and committee structure

This section establishes who has authority to make, ratify, and veto investment decisions. A best-practice framework specifies the investment committee's composition (recommended: three to five members, with at least one independent external advisor), quorum requirements for decisions above defined thresholds, and a formal conflict-of-interest protocol. For family offices where a principal or patriarch retains override authority, that authority should be documented explicitly — including its limits. Undocumented override culture is among the leading causes of governance breakdown in family offices during leadership transitions. The section should also cross-reference the family's broader governance documents, including any family constitution or shareholder agreement, to ensure consistency.

Section three: investment objectives and time horizon

Objectives must be specific and internally consistent. A target of "preserving real wealth across generations" is not an investment objective — it is an aspiration. A properly written objective might read: "Achieve a net annualised real return of 4.5% over rolling ten-year periods, sufficient to fund annual family distributions of 3% of net asset value while maintaining the portfolio's inflation-adjusted principal." This formulation links the return target directly to the distribution policy and the preservation mandate, which allows the asset allocation in Section Four to be derived rationally rather than arbitrarily. Time horizon should be stated explicitly for each capital pool if the family maintains separate buckets — for instance, a liquidity reserve (0-3 years), a core growth portfolio (7-15 years), and an intergenerational endowment pool (20+ years).

Section four: strategic asset allocation policy

Rather than fixed point targets, strategic asset allocation should be expressed as policy bands with a midpoint. For example: global listed equities 30-45% (midpoint 38%), private equity and venture 15-25% (midpoint 20%), real assets including infrastructure and real estate 10-20% (midpoint 15%), fixed income and credit 10-20% (midpoint 15%), and cash and liquid alternatives 5-15% (midpoint 8%). The band structure gives the investment committee rebalancing latitude without triggering a formal IPS amendment every time markets move a few percentage points. The section should also specify rebalancing triggers — both calendar-based (quarterly review) and threshold-based (any asset class drifting more than five percentage points from its midpoint). Importantly, the IPS must address how illiquid assets are valued for allocation monitoring purposes, since private equity NAV reporting typically lags by one quarter or more.

Section five: risk management and liquidity framework

This section is where the distinction between risk tolerance and risk capacity becomes operationally critical. Risk tolerance is a behavioural and psychological measure — the degree of loss a family can absorb emotionally before their decision-making deteriorates. Risk capacity is a financial measure — the degree of loss the portfolio can sustain without impairing the family's ability to meet its obligations. The two are frequently misaligned. A second-generation family with substantial illiquid real estate holdings may have low risk capacity (significant debt service, low liquid reserves) but high expressed risk tolerance. An IPS that governs to tolerance rather than capacity will eventually produce a liquidity crisis.

Risk capacity, not risk tolerance, should set the ceiling on portfolio risk. Tolerance informs communication; capacity governs construction.

The liquidity policy within this section should specify a minimum liquid reserve — typically expressed as 12 to 24 months of projected distributions, family expenses, and debt service obligations held in instruments realisable within 30 days. For a family office with annual cash obligations of £4 million, this implies a minimum liquid buffer of £4-8 million in short-duration investment-grade instruments or cash equivalents. The section should also set maximum illiquidity limits — commonly, no more than 35-40% of the total portfolio in assets with redemption periods exceeding 12 months — and require stress testing against scenarios including a 30% drawdown in listed equities concurrent with a 6-month delay in private equity distributions.

Section six: compliance, reporting, and cross-border obligations

For families with assets or beneficiaries in multiple jurisdictions, this section is non-negotiable. The IPS must identify the family's reporting obligations under FATCA and the OECD's Common Reporting Standard (CRS), note any entities that qualify as Passive Non-Financial Entities under CRS, and flag AIFMD obligations for any pooled vehicles managed from within the EU. For families with structures potentially caught by BEPS Pillar Two — particularly relevant for those with consolidated revenues approaching or exceeding the €750 million threshold at the group level — the IPS should note the minimum 15% global minimum tax exposure and its implications for structuring decisions. This section does not replace legal counsel, but it ensures that compliance awareness is embedded in investment governance rather than siloed in a separate function.

Governance review cadence: the two-frequency model

An IPS that is reviewed only when something goes wrong is not a governance document — it is a crisis manual. Best practice structures reviews at two distinct frequencies, each with a different scope and set of participants.

The annual operational review examines whether the current asset allocation remains within policy bands, whether manager mandates are being executed as agreed, whether the liquidity buffer remains adequate given the prior year's cash flow, and whether any new regulatory developments — a change in CRS reporting requirements, for instance, or an update to AIFMD II implementation timelines — require IPS amendments. This review is conducted by the investment committee and the chief investment officer, and its conclusions are documented in formal minutes.

The triennial governance review is a more fundamental reassessment. It should involve the full investment committee, key family principals, and in most cases, an external governance advisor. The scope expands to include a reassessment of the family's risk capacity (which changes as balance sheets, family structures, and obligations evolve), a review of the return objectives in light of current capital market assumptions, a consideration of generational priorities as the next generation begins to engage with family wealth, and a formal assessment of whether the governance structure itself — the committee composition, quorum rules, and authority framework — remains fit for purpose. Research from the Institute for Private Investors suggests that family wealth transitions fail at a higher rate when governance documents have not been updated in the five years preceding a generational transfer. The triennial review is the structural mechanism for preventing that failure.

Integrating the IPS with the broader family governance architecture

The IPS does not operate in isolation. Its effectiveness depends on its coherence with the family's broader governance architecture: the family constitution (which sets values and long-term purpose), the trust deed or partnership agreement (which sets legal obligations), the distribution policy (which drives the liquidity requirements that constrain investment risk-taking), and the family office's operational manual (which governs day-to-day execution). When these documents are written independently by different advisors at different times, contradictions emerge. A trust deed that requires distributions to be funded exclusively from income will conflict with a total-return IPS that reinvests dividends and relies on asset sales to fund distributions. A family constitution that mandates 10% annual giving to philanthropy must be reflected in the IPS's liquidity framework.

The practical recommendation is to conduct a document consistency audit whenever a new IPS is being drafted or substantially revised. Map each material commitment in the IPS — the return target, the liquidity buffer, the illiquidity ceiling, the rebalancing triggers — against the corresponding provisions in the family's other governing documents. Where inconsistencies exist, resolve them explicitly, in writing, with input from both legal and investment advisors. An IPS that accurately reflects the family's full set of constraints and obligations is a genuinely useful governance tool. One that does not is, at best, decorative, and at worst, actively misleading to new trustees, incoming family members, or external auditors reviewing the family's governance standards.

The IPS's durability across generations depends not on the sophistication of its asset allocation framework, but on the clarity and consistency of its governance provisions — the sections that most advisors draft last and least carefully.
