Investment Mandate · version 1.2 · 14 August 2026
The mandate, in summary
Every figure below is a clause, not a preference. A limit that a document says should “not normally” be exceeded gives the Risk Officer no objective test to apply, so each one here states a hard limit that a purchase may never breach, a tolerance band for breaches caused by price movement, and a period within which the position has to come back.
Document status
Document status
Draft, pending written approval from the Academic Adviser. It does not take effect until Appendix A is complete: the source and size of the capital, the broker, the commission schedule, the strategic geographic weights for the year, and the exclusion screening source in use. Several provisions below are inert until those numbers exist.
Section 2 (legal status and regulatory position) and Section 17 (allocation of surplus) are stated as governance intent and are to be confirmed with University Finance and, where relevant, Legal Services before adoption. Neither this page nor the mandate is legal advice.
01 Instruments
The investable universe
Permitted §4.1
- Listed ordinary shares on recognised, regulated exchanges in developed markets only.
- Exchange traded funds and index funds giving diversified equity exposure, subject to the pooled fund test at §4.4.
- Emerging market exposure through pooled funds only. Direct holdings in emerging market securities are not permitted.
- Cash at the broker and highly liquid money market instruments.
Prohibited §4.2
- Derivatives of any kind: options, futures, swaps, contracts for difference, spread bets.
- Leverage and margin. The fund may not borrow to invest under any circumstances.
- Short selling in any form, direct or synthetic.
- Cryptoassets and unregulated digital tokens.
- Unlisted or private securities, crowdfunding, peer-to-peer lending.
- Anything the Committee cannot value from a publicly available daily price.
No position may be taken where the fund’s intended holding could not be liquidated in full within three trading days without exceeding 10% of the security’s average daily traded volume over the preceding 30 days (§14.3).
02 Exclusions
Values-based exclusions
Thresholds rather than adjectives, so the policy is applied consistently rather than interpreted case by case.
| Excluded activity | Threshold |
|---|---|
| Extraction, production, refining, storage or transport of oil, gas or coal | 5% |
| Thermal coal, oil sands, and power generation from coal | 0% |
| Armaments and weapons systems | 5%, and 0% for controversial weapons: cluster munitions, anti-personnel landmines, and biological, chemical and nuclear weapons |
| Gambling operations | 5% |
| Tobacco | 0% for production, 5% for distribution and retail |
| Adult entertainment | 5% |
A company assessed as being in serious and ongoing breach of the Ten Principles of the UN Global Compact is also excluded. The Committee applies one documented screening source, names it in the annual report, and may not take a position where a company’s revenue split cannot be established from public disclosure. The fossil fuel threshold applies to companies whose business is the fossil fuel value chain; it does not automatically exclude a diversified industrial, utility or financial company with incidental exposure. Borderline cases are decided by the Committee and the reasoning is minuted, so a body of precedent builds up.
Pooled funds are tested on their methodology
A pooled fund is held for diversification and cannot be screened company by company at the point of purchase the way a direct holding can, so the exclusions apply to it at the level of its published index or investment methodology. A fund qualifies only where those screens are binding and materially consistent with §4.3. It is easy to prohibit an activity in one clause and then hold a great deal of it through a fund named as though it did the same, which is what this section exists to prevent.
- Usually not eligible
- “ESG Aware”, “ESG Enhanced”, “ESG Focus”, “ESG Leaders”, “ESG tilted”. Optimisations that raise an aggregate score while tracking a conventional parent index; they commonly retain conventional oil and gas producers.
- Usually eligible
- “SRI”, “Screened”, “ex Fossil Fuels”, “Fossil Fuel Free”, “ESG Exclusionary”. Binding exclusions, generally consistent with §4.3.
- Before purchase
- The proposing Portfolio Manager obtains the current factsheet, prospectus or index methodology and completes the Appendix C checklist, confirming in writing to the Risk & Compliance Officer. It is filed with the pitch.
- Afterwards
- Re-verified at the annual review and whenever the provider announces a methodology or index change. A holding that stops complying is reported and disposed of within 60 calendar days unless the Committee resolves otherwise with written reasons in the minutes.
03 Allocation
Where the money sits
Bands, not a strategic allocation. The Committee sets the actual weights within them at each annual review and records them in the annual report.
| Asset class | Range | Why |
|---|---|---|
| Equities, direct holdings | 60–80% | Core growth driver, and the primary vehicle for the educational objective |
| Pooled funds | 15–30% | Low-cost access to markets a student team cannot research directly |
| Cash and equivalents | 5–15% | Liquidity buffer, and capacity to act without becoming a forced seller |
The endpoints are not meant to sum to 100%. Combined equity and pooled fund exposure will normally sit between 85% and 95% of net asset value.
| Geography | Range | Access route |
|---|---|---|
| United Kingdom | 20–40% | Direct equities and UK-listed pooled funds |
| United States | 30–50% | Direct equities and pooled funds |
| International developed, ex-UK and ex-US | 10–30% | Direct equities and pooled funds |
| Emerging markets | 0–10% | Screened pooled funds only |
Measured on invested assets rather than total net asset value, so a change in the cash weighting does not by itself create a geographic breach. The strategic weights set at the annual review must sum to 100% of invested assets, and they determine the composite benchmark below.
04 Limits
Concentration limits
A hard limit a purchase may never breach; a tolerance band for a breach caused by price movement; a period within which the position must come back.
| Limit | Hard limit | Tolerance | Cure period |
|---|---|---|---|
| Single direct equity holding | 10% at purchase | 12% | 10 business days |
| Single pooled fund | 20% at purchase | 23% | 10 business days |
| Sector exposure, look-through | 30% | 35% | 20 business days |
| Cash | floor 5% / ceiling 15% | floor 3% / ceiling 25% | 20 business days |
| Number of direct equity holdings | maximum 20 | None | next quarterly review |
| Minimum direct position size | 2% at purchase | None | Not applicable |
| Leverage, margin or short exposure | 0%, absolute | None | immediate |
A proposed purchase that would take the fund past a hard limit is rejected by the Risk & Compliance Officer. There is no discretion and no override, including by the Academic Adviser. A passive breach, caused by price or net asset value movement rather than a purchase, is still a breach: it is logged and reported whether or not it is cured in time.
Sector exposure is measured look-through: direct holdings at full weight, plus the fund’s proportionate share of each pooled fund’s published sector weights. A broad market tracker may itself carry 30% or more in one sector, so counting only direct holdings would understate real concentration by design.
05 Benchmark
The Prune Hill Composite
A benchmark is the passive alternative to the whole strategy, so it has to match the portfolio’s geography, its currency, its cash holding and its exclusions.
| Component | Weight | Index basis |
|---|---|---|
| UK equities | 27% | Broad UK index applying fossil fuel and controversial sector exclusions |
| US equities | 40% | Broad US index applying equivalent exclusions |
| International developed, ex-UK and ex-US | 18% | Broad developed ex-North-America index, equivalent exclusions |
| Emerging markets | 5% | Broad emerging markets index, equivalent exclusions |
| Cash | 10% | SONIA, compounded |
Measured in sterling, unhedged, total return with gross dividends reinvested. The 10% cash component is there so the fund is not measured against a fully invested benchmark while holding the liquidity buffer this mandate requires: without it, the comparison would penalise the fund for obeying its own cash floor in a rising market and flatter it in a falling one.
Where index-level data is not accessible, a tracker’s net asset value may stand in as a documented proxy, provided it is fixed in advance for the year, named in the annual report, and the report says that a tracker’s return is net of its ongoing charges and therefore understates the index by roughly that amount. Benchmark changes take effect prospectively only; historic performance is always shown against the benchmark that was in force at the time.
06 Risk
Triggers, and the review each one starts
Three triggers, three different reviews. A falling market and a broken process are not the same failure and do not get the same response.
| Trigger | Threshold | Consequence |
|---|---|---|
| Absolute drawdown | 15% over any rolling six months, or 20% over any rolling twelve | Portfolio Review: concentration, exposure, liquidity, and whether the decline is market-wide or position-specific |
| Relative underperformance | 8 percentage points below the composite over any rolling twelve months | Process Review: pitch quality, whether the risks identified at the time actually materialised, whether sell discipline was applied |
| Uncured limit breach | Any breach not cured within its cure period | Governance Review |
A drawdown caused by market-wide conditions is not evidence of poor performance by any officer and does not on its own trigger any review of leadership. That separation is deliberate: coupling a market outcome to personal consequences gives a team facing a falling market a reason to sell into weakness or to delay reporting, and both are the opposite of what a fund whose primary purpose is educational exists to teach. A leadership review follows only where one of the three reviews above finds a breach, a failure of process, or a failure of governance.
The fund expects periods of significant decline. Equity market falls of 20% or more happen periodically and are a normal characteristic of the asset class (§8.1). No leverage may be used in any market condition, including to recover a drawdown (§8.7).
07 Breaches
Reporting a breach
| Category | Definition | Escalation |
|---|---|---|
| Active | A trade executed that breached a hard limit at the point of trade | Academic Adviser within one business day; corrected immediately; Advisory Board at its next meeting |
| Passive | A limit exceeded through price or net asset value movement | Logged; cured within the cure period |
| Process | A decision taken without quorum, without a written pitch, or without a pre-trade check | Academic Adviser within five business days; reviewed by the Committee |
| Compliance | A holding that stops satisfying the exclusion policy | Reported, and disposed of within 60 calendar days unless the Committee resolves otherwise in writing |
Concealing or delaying the report of a breach is treated more seriously than the breach itself.
Investment Mandate v1.2, §16.5
08 Also in it
The clauses that rarely make a summary
Costs, stewardship, personal dealing, selling, and what happens to any surplus. Open whichever matters to you.
§10 Costs and trade economics
The fund is small relative to institutional portfolios, so commission, stamp duty, spread, currency conversion and ongoing fund charges can be a material share of return. Cost is treated as a risk. A trade may not be executed where the estimated total round-trip cost exceeds 1.0% of the trade value, which in practice sets a minimum sensible trade size; the Operations & Reporting Officer calculates it and updates it whenever the broker’s schedule changes.
The 2% minimum position size and the 20-holding maximum exist for the same reason: a long tail of tiny positions justifies neither its dealing costs nor the research time to monitor it, and a student team cannot genuinely cover more than twenty names alongside a degree. Where two funds offer equivalent exposure and equivalent compliant methodology, the cheaper one is preferred and any decision to the contrary is justified in the minutes. All reported performance is net of everything in this section.
§7.5 Sell discipline
Buying is the part every fund documents; selling is the part that decides the return. A position is reviewed for sale where the original thesis is invalidated or a stated key assumption proves wrong; where it breaches or would breach a limit; where it stops complying with the exclusion policy; where the valuation reaches the target set in the original pitch; or where it has materially underperformed its sector or the composite over a rolling twelve months without a reason the Committee accepts.
A review does not compel a sale. Hold, trim or exit, the outcome is minuted with reasons every time. There are no automatic stop-losses: selling decisions are made on the thesis, not on price movement alone.
§11 Valuation and performance measurement
Net asset value is struck monthly at the close of the last business day, using closing prices and the broker’s published closing exchange rates. Returns are time-weighted, in sterling, net of all dealing, currency and pooled fund costs. Time-weighted return is used because it measures the Committee’s decisions independently of when capital happens to arrive, which the Committee does not control. A money-weighted return may be reported additionally where flows are material, clearly labelled as such.
Periods shorter than twelve months are reported as cumulative returns and are never annualised or extrapolated. The Operations & Reporting Officer prepares the figure, the Risk & Compliance Officer verifies it independently against the broker statement, and the Academic Adviser signs it off quarterly. No performance figure may be published externally, used in recruitment or sponsorship material, or included in any member’s personal materials before that sign-off. Any error in a published figure is corrected, the correction disclosed, and the reason minuted.
§12 Stewardship and voting
The exclusion policy governs what the fund will not own; stewardship governs how it behaves as an owner of what it does hold. For a fund with an explicit sustainability mandate, silence on ownership rights would be an inconsistency, and voting the fund’s shares is one of the few things a student fund can do that most do not.
Where practical the fund votes its direct holdings, instructed by the Academic Adviser on the Committee’s recommendation. The default is to support the board, except on resolutions concerning climate transition planning, environmental disclosure, human rights due diligence or executive remuneration, where the Committee forms and minutes its own view first. The full voting record for the year is published in the annual report. The fund does not vote the underlying holdings of pooled funds, does not engage in activism, and does not join collective engagement initiatives without written approval.
§13 Conflicts and personal account dealing
Before pitching or voting on a security, every member declares any personal holding in it or its direct competitors, any family interest, and any employment, internship or live application relationship with the issuer. A declared interest means presenting and answering questions but not voting, and the abstention is minuted.
No member may deal personally in a security for five business days either side of the fund dealing in it, or on the basis of a pitch that has been circulated but not yet decided. The Risk & Compliance Officer keeps the register, and declarations are recorded whether or not they result in an abstention. Members may reference their own work in job applications and share pitches they personally authored; they may not disclose live holdings, intended trades or unpublished performance.
§17 Surplus and hardship support
All gains are retained while the fund grows. A distribution may be made for a financial year only if the fund has a continuous track record of at least three full financial years; its net asset value exceeds the minimum threshold agreed in writing with the Academic Adviser; the value immediately after the distribution would remain above the aggregate capital contributed to the fund; the Academic Adviser and University Finance have approved that year in writing; and no breach is outstanding.
The maximum is the lower of 4% of average month-end net asset value over the preceding three financial years and 30% of the fund’s total return for that year. It goes only to an approved University hardship, bursary or access fund, never to an individual student or staff member and never to the fund’s own members. Any distribution is disclosed in the annual report with the full calculation.
The rule is deliberately written against average net asset value rather than against realised profits. Tying a distribution to realised gains would give a team that wants to fund bursaries a reason to sell holdings, which works against the long-term horizon stated two sections earlier, and would allow a payout out of realised gains while unrealised losses sat in the portfolio. An endowment-style spending rule avoids both, and is what university endowments use.
§3, §18 Continuity and amendment
Officer terms run for one academic year, each role has a named deputy who may act with its full authority, and outgoing officers overlap with their successors for at least four weeks and leave a written handover pack: current holdings and the reasoning behind each, open items, the risk register, access details, and any outstanding breaches. Records belong to the University and are not held solely in personal accounts.
Meetings are suspended during formal examination periods, and between the end of the summer examinations and the start of Michaelmas the portfolio is held on a monitoring-only basis: no new position without written approval. The mandate is reviewed at least annually, amendments need written approval from the Academic Adviser, and changes to the sections on legal status, prohibited instruments, concentration limits or surplus additionally require consulting the Advisory Board. Amendments take effect prospectively only, so the mandate in force at the time governs any past decision. Where the mandate is silent, or two provisions conflict, the more conservative reading applies.
