The NAV Error Policy Hedge Fund Boards Should Approve: Thresholds, Compensation and Restatements

A NAV error policy hedge fund directors can defend answers four questions before any error occurs: how the error is measured, at what size it becomes material, who is compensated, and who pays. The CIMA Rule on Calculation of Asset Values for Regulated Mutual Funds, issued in July 2020, requires a written NAV Calculation Policy that keeps the NAV "free from material error". It defines no threshold and prescribes no compensation procedure. Those decisions belong to the fund's operators and are settled by market convention, the administration agreement and the offering document. This article sets out where errors come from, the thresholds seen in practice and in two European regimes cited as reference points, who compensates whom, and what the policy and offering document should say.

"Every fund we have seen restate a NAV had a valuation policy. What separated the orderly restatements from the damaging ones was whether the policy had already decided the hard questions: the threshold, the direction of compensation, the de minimis amount and who signs the investor letter. When those are settled in advance, the board is approving a calculation. When they are not, the board is negotiating with the manager and the administrator about money while investors wait for a corrected statement. We would rather the argument happened at launch, on paper, than after the error, in a hurry." David Lloyd, Chief Executive Officer at CV5 Capital

Executive Summary

NAV errors are an operational certainty. The Cayman framework requires a policy that addresses them and leaves its design to the fund's operators.

• Rule 5.1 of the CIMA Rule requires a NAV Calculation Policy that keeps the NAV free from material error, and Rule 5.4.7 an escalation and resolution procedure for exceptions.
• The Rule sets no numerical threshold and no compensation mechanics; those are market practice and contract, and the policy should label them as such.
• Thresholds published by the Luxembourg and Irish regulators are reference points for a Cayman board, not Cayman requirements.
• Who is compensated depends on the direction of the error and whether the investor subscribed, redeemed or held through the error period.
• Who pays depends on the cause, on the administration agreement's standard of care and liability cap, and on the manager's commercial judgement.
• A restatement reopens performance fees, equalisation and series accounting, so the error procedure must link to the fee methodology.

Where NAV Errors Actually Come From

Most NAV errors are not valuation judgements gone wrong. They are process failures in the chain from trade capture through pricing, accruals and cash to the per share figure. A stale vendor price, a corporate action booked on the wrong date, a fee accrued at the wrong rate or an FX rate taken at the wrong cut-off will each move the NAV. Nobody formed a view about fair value.

Detection controls follow from cause, and a policy that addresses only hard-to-value assets will miss most of the errors a hedge fund experiences. Pricing judgement for Level 3 positions belongs to the framework in valuing hard-to-value assets and the role of the valuation committee; the controls in the table are for everything else.

Most of these controls sit with the administrator. A manager who has not asked how they operate has no basis for the assurance it gives investors; the questions are in what managers should ask a fund administrator before launch. A manager running a shadow NAV catches a meaningful share of these errors itself, and CV5 sets out where that function should sit in what to outsource and what to own in the middle office.

What the CIMA Rule Requires, and What It Leaves to the Board

The CIMA Rule on Calculation of Asset Values for Regulated Mutual Funds, issued in July 2020, applies to every fund licensed or registered under section 4 of the Mutual Funds Act. Rule 5.1 requires a fund to establish, implement and maintain a NAV Calculation Policy that ensures the NAV is "fair, complete, neutral and free from material error and is verifiable". Rule 5.4 requires the policy to be written and disclosed in the offering document and to define the role of each service provider in the valuation process. Rule 5.4.7 requires it to identify price sources for each instrument type and "a practical escalation of resolution procedure for the management of exceptions". Rule 5.4.8 requires proportionate internal controls.

Three further provisions bear on an error once found. Rule 5.7 provides that deviations from the policy which affect the reported NAV must be immediately disclosed to investors and agreed by the operators in advance. Rule 5.13 requires the NAV to be communicated directly to investors by the service provider charged with the calculation, so a corrected NAV comes from the administrator. Rule 5.14 places ultimate responsibility for oversight of the valuation process on the operators, who for a Cayman company are the directors, and who must approve and review the policy at least annually.

What the Rule does not do matters as much. It does not define "material error", sets no percentage threshold, and says nothing about who is compensated, who pays, de minimis amounts or performance fees. Those are market practice and contract, and the policy should say so rather than present its thresholds as regulatory requirements. The error procedure is one section of the wider document described in what a defensible fund valuation policy contains.

Materiality Thresholds: Market Practice and Two Regulatory Reference Points

A materiality threshold separates errors that are corrected at source and logged from errors that trigger a recalculation of every affected NAV, a compensation exercise and investor communication. It gives the administrator, the manager and the board a shared definition, so that classifying an error is not itself a negotiation. It is usually a percentage of NAV per share on the affected dealing date, sometimes paired with an absolute monetary floor.

In hedge fund practice, valuation policies commonly set the threshold between 0.5 per cent and 1 per cent of NAV for equity, multi-strategy and other diversified strategies. Fixed income and cash-like strategies use lower figures, because a given error is proportionately more significant. That is convention, not a rule, and a board may set a lower figure or different figures by segregated portfolio. Two European regulators have published thresholds, and they are useful precisely because Cayman has not. Neither applies to a Cayman fund, and neither should be cited in a Cayman policy as anything other than a comparator.

Two features of the Luxembourg circular are worth borrowing whatever number is chosen. Successive errors each below the threshold that together reach it are treated as one significant error. And the threshold is fixed per sub-fund before the first NAV and applied consistently. Both map directly onto a segregated portfolio company.

Who Is Compensated, and by Whom

Once an error is material, the fund recalculates the NAV for every dealing date in the error period and works out who dealt at the wrong price. The analysis turns on the direction of the error and on what each investor did. An investor who neither subscribed nor redeemed has usually suffered no dealing loss, because the correction restores the fund's value. Those who gained or lost are those who transacted, and the fund is diluted whenever a transaction went the wrong way.

The matrix mirrors the Luxembourg circular, which distinguishes investors who redeemed at an undervalued NAV from those who subscribed at an overvalued one, and which allows the fund to seek reimbursement from professional investors who benefited. Whether a Cayman fund pursues recovery is a board judgement. The commercial answer is often no, in which case the fund must be made whole by someone else, and that is where the question of who pays becomes real.

The fund, the manager or the administrator

The starting point is cause. Where the error originated in the administrator's process, the administration agreement governs. Most agreements set a standard of care under which the administrator is liable only for negligence, wilful default or fraud, and many require gross negligence. Most also cap liability, often at a multiple of annual fees, and exclude consequential loss. A manager who has not read those clauses discovers during a restatement that the administrator's exposure is a fraction of the compensation due.

Where the manager supplied a wrong price or a late trade file, the manager will usually be expected to pay, on the same principle by which the trade error policy allocates losses between manager and fund. Where the cause is a vendor feed both parties relied on in good faith, the answer is negotiated on principles the policy should set in advance. A manager who absorbs a loss it did not strictly cause should record that as a board minute and a manager contribution, not as a silent adjustment in the NAV.

The de minimis amount

A de minimis threshold is the amount per investor below which compensation is not paid, because paying it would cost more than it is worth. The Luxembourg circular permits one, fixed as a lump sum per fund by reference to the bank charges investors would bear, and does not apply it to compensation owed to the fund. The Irish consultation paper recorded industry practice at the time as EUR 50 for retail and EUR 500 for institutional investors, and questioned whether those levels were too high. For a hedge fund the usual answer is to compensate continuing investors in additional shares, which needs no bank transfer, and to set a modest cash de minimis for investors who have fully redeemed.

Performance Fees, Equalisation and Series After a Restatement

A corrected NAV changes every calculation that depended on the wrong one. If the performance fee crystallised during the error period, it was calculated on the wrong gain and the high water mark was set at the wrong level. Any equalisation credits or contingent redemptions were computed from the wrong per share figure. In a series structure, each series issued in the period has the wrong opening NAV and any roll-up was at the wrong ratio. None of this is cured by restating the headline NAV; the fee and equalisation schedule must be rerun.

The interaction cuts both ways. An overcharged fee produces a repayment from the manager to the fund, which itself changes the corrected NAV. An undercharged fee raises the question of whether the manager should recover the shortfall, which most managers decline to do. The policy should state the principle in advance: fees are corrected in the same exercise as the NAV, repayments are made without deduction, and shortfalls are not recovered unless the board decides otherwise.

The mechanics a restatement disturbs are explained in how equalisation and series accounting keep performance fees fair. Where lock-ups, gates or side pockets were calculated from the wrong NAV, the recalculation must run at investor level across the whole period.

Governance: The Board, the Auditor and the Investor Letter

Under Rule 5.14 the directors own the valuation process, so the board approves the classification of an error as material, the corrected NAVs, the compensation plan and the investor letter. In practice the administrator prepares an error memorandum setting out the cause, the error period, the published and corrected NAV for each dealing date, the investors affected and the amounts due. The manager states its position on who pays. The board decides, minutes the decision and instructs the administrator to communicate; an audit or governance committee may review the memorandum first, but the decision remains the board's. How this fits the board's wider oversight is set out in what institutions expect from valuation, NAV production and investor reporting in a Cayman hedge fund.

The auditor is told at classification, not at year end. A restatement within the year is an event the auditor will test, and one that crosses a year end may require the prior year's financial statements to be considered. The auditor will also want the error log, including sub-threshold errors, because a pattern of small errors from one cause is evidence about the control environment.

Investor communication follows three principles. Investors who dealt at a wrong NAV are told what happened, what the corrected NAV was, what they are owed or asked to repay, and when. All investors receive the corrected NAV through the administrator, consistent with Rule 5.13, with a short explanation of cause and remediation. And the letter goes out only once the board has approved the numbers, in plain terms, because a restatement handled transparently is a better answer to operational due diligence than one that was minimised.

What the Valuation Policy and the Offering Document Should Say

The NAV Calculation Policy is disclosed in the offering document under Rule 5.4.1, so the error procedure is disclosed with it. The offering document states the principles and the policy states the mechanics. The offering document should say that NAV errors may occur and that a written procedure governs their escalation and correction. It should say that errors above a stated threshold result in recalculation and, where appropriate, compensation, and that errors below it are corrected without restatement. It should reserve the fund's right to seek recovery from investors who benefited and describe the de minimis approach.

Where the manager prices any part of the portfolio, Rule 5.12 requires disclosure of that involvement and its conflicts. The policy itself should cover the items below, each a board decision at approval and on annual review under Rule 5.14.

• The definition of a NAV error, distinguished from a valuation judgement that later proves wrong after the policy was followed on the information then available.
• The materiality threshold, any absolute monetary floor, and the treatment of aggregated sub-threshold errors.
• The escalation path: who the administrator notifies, within what time, and who classifies the error.
• The compensation matrix, the de minimis amount, whether continuing investors receive cash or shares, and the allocation of cost between fund, manager and administrator by cause.
• The treatment of performance fees, equalisation, series and any lock-up, gate or side pocket calculation affected.
• The approvals required, the auditor notification point, the investor communication, and the error log with its annual review of causes and controls.

On the CV5 platform the policy is a document of the segregated portfolio company, approved by its board and applied by the independent administrator to each segregated portfolio, with thresholds capable of being set by portfolio. CV5 provides the governance framework, the administrator relationship and the escalation architecture. The manager remains responsible for the strategy, for the accuracy of any prices or trade data it supplies, and for its share of any compensation the board determines is due. The wider structure is described on the CV5 hedge fund platform page.

Key Takeaways

• Write the NAV error procedure into the valuation policy before launch, labelling each element as regulatory requirement, market practice or contract.
• Set the threshold per segregated portfolio by strategy, fix it before the first NAV, and count aggregated sub-threshold errors from one cause against it.
• Decide the compensation matrix now, including whether the fund will pursue investors who benefited and how continuing investors are made whole.
• Read the administration agreement's standard of care and liability cap as part of the error policy; they determine what the administrator can be asked to fund.
• Treat every restatement as a fee event: rerun performance fees, equalisation and series at investor level, and record any manager repayment as a board decision.
• Notify the auditor at classification, issue the investor letter through the administrator after board approval, and log the errors that did not trigger a restatement.

Frequently Asked Questions

What is a NAV error policy in a hedge fund?

A NAV error policy is the section of a fund's valuation policy that defines what counts as a NAV calculation error and the threshold above which an error is material. It also sets how errors are escalated and classified, who is compensated and by whom, and how the correction is communicated. For a Cayman regulated mutual fund it forms part of the NAV Calculation Policy required by the CIMA Rule on Calculation of Asset Values. That Rule requires an escalation and resolution procedure but leaves thresholds and compensation mechanics to the fund's operators.

What materiality threshold do hedge funds use for NAV errors?

There is no Cayman regulatory threshold. In practice, hedge fund valuation policies commonly set the threshold between 0.5 per cent and 1 per cent of NAV per share for equity and diversified strategies, and lower for fixed income and cash-like strategies. The Luxembourg regulator's Circular 24/856 publishes thresholds of 0.20 per cent for money market funds, 0.50 per cent for bond and mixed funds and 1.00 per cent for equity funds. The Central Bank of Ireland proposed 0.10 per cent and 0.50 per cent in a 2019 consultation paper. Those are reference points for a Cayman board, not requirements.

Who compensates investors for a NAV error?

It depends on the cause. Where the administrator's process caused the error, the administration agreement governs, and its standard of care and liability cap will usually limit what the administrator pays. Where the manager supplied a wrong price or wrong trade data, the manager is generally expected to fund the compensation. Where neither party is at fault, the allocation is negotiated on the principles set out in the policy, and managers often absorb the loss to protect the investor relationship. The fund itself should not bear the cost of investigating an error it did not cause.

Does a NAV error require a restatement?

Only if it is material under the fund's policy. Errors below the threshold are corrected at source, logged and reflected in the next NAV without restating earlier ones. Errors at or above the threshold require the NAV to be recalculated for every dealing date in the error period and a compensation analysis for investors who subscribed or redeemed at the wrong price. The board approves the result and the corrected NAV is communicated to investors through the administrator.

How does a NAV restatement affect performance fees?

A corrected NAV changes the gain on which any performance fee crystallised during the error period was calculated, the high water mark, and any equalisation or series calculation. The fee schedule must be rerun at investor level for the period. Where the fee was overcharged, the manager repays the fund. Where it was undercharged, most managers do not recover the shortfall from investors, and the policy should state the fund's position in advance.

Does CIMA need to be notified of a NAV error?

The CIMA Rule on Calculation of Asset Values does not itself contain a NAV error notification requirement, in contrast to the Luxembourg circular, which requires significant errors to be notified to the CSSF. Whether a particular error engages any other reporting obligation, for example through the audited financial statements or the auditor's own duties, depends on the facts and should be considered with independent professional advice at the time.
