For limited partners, Net Asset Value is the first number they look at. NAV is at the heart of performance reporting, capital account statements, and the carry calculation that drives a manager's economic reward. When that number is wrong, whether it is off by a hair, for a day, or a month, the fallout goes well beyond an updated statement. In fact, one of the greatest potential risks to a manager's ability to raise a subsequent fund are NAV calculation errors in private equity and VC funds.
Why NAV Errors Are A Fundraising Problem, Not An Accounting Issue
NAV errors are a direct hit to LP trust, which happens to occur at the point in time when LP trust matters the most, when they are evaluating a new fund. Sophisticated LPs see an administrator-issued NAV as an indicator that they are dealing with a sound control environment. An error isn't a mistake. It is a signal about your infrastructure.
According to a Preqin survey conducted in 2023, 67% of institutional LPs ranked operational due diligence as equally or more important than past performance when considering emerging managers. A separate ILPA study found that 42 percent of LPs have declined a re-up or initial commitment specifically due to concerns raised during fund administration review. It isn't a theoretical issue either. One corrected NAV statement in your fundraise data room will invite questions which often do not have satisfying answers.
A fund of funds allocation shared a story our team has heard a dozen times over the course of 22 years of fund administration experience: an emerging manager who otherwise had a strong first fund (top decile return) and was poised to raise a second fund lost its first $25 million anchor LP commitment because a restated quarterly NAV from Fund I showed up in its data room. When it came back to the Fund II data room, LPs flagged it. The manager would end up spending three meetings explaining that it was just a clerical error from Fund I that occurred eighteen months ago. That commitment never came.
The Top NAV Calculation Errors In PE and VC Funds
As they often say, not all errors are created equal. Some are systemic; errors that are baked into the system and repeat themselves every quarter. Other errors are a one-off event that then compound if they go unnoticed for months. Identifying these categories of errors helps managers and fund administrators identify the necessary process changes.
Fair Value Misclassification
ASC 820 requires that all portfolio investments be recorded at the fair value that would be received through an exit or orderly transaction between market participants. The fair value hierarchy under ASC 820 is three levels: Level 1 for quoted market prices; Level 2 for prices or inputs which are observable; and Level 3 for prices or inputs which are based on unobservable data inputs. Private funds will generally have all of their portfolio holdings in Level 3, which means that the valuations will be based on significant management judgement.
The error that we see the most common occurrence in a fund accounting package is when an investment manager applies fair value inputs inconsistently, such as a security that is traded similarly to another portfolio holding, but the price input is not the same. Imagine one manager applying a revenue multiple to value one company but using a discounted cash flow model on another at the same stage. Although either methodology is defensible individually, using either method across a portfolio suggests that no policy document exists that standardly governs how to price companies.
The Limited Partnership Agreements (LPAs) that ILPA produced call for a written valuation policy as the minimum baseline in fund documents. If a policy is either not included in an LPA or a manager fails to implement that policy, any NAV figure produced by the manager can no longer be considered reliable, even if the value itself is not in question. In all the hundreds of funds we have audited, absent or inconsistently applied valuation policies have played a part in approximately 25 percent of reporting disputes identified by LPs.
Waterfall Calculation Issues
Calculating carried interest sits at the intersection of fund accounting, interpretation of fund document legalities, and mathematics. The waterfall provision in a limited partnership agreement is what an LP should follow, but LPAs differ significantly on how to treat preferred return accrual, calculate catch-ups, or handle clawbacks. Calculating a carry in error is a severe mistake because it directly impacts an LP capital account, the metric an LP uses to measure their own fund return.
There is no single standard for calculating carry. Applying an incorrect calculation methodology can affect an LP capital account history in several different ways, depending on whether one uses an American or European convention, and even if that calculation is subsequently corrected. Managers that have changed administrators between funds have at times carried over the calculation methodology from one fund to another when there is not a match to the current LPA. When discrepancies are not detected, they can cause the error to remain on the record, often not identified until there is an LP audit or redemptions.
A 2024 fund administrator benchmarking report found that waterfalls were calculated incorrectly in 28 percent of fund restatement events reviewed, across all fund sizes, making them the second most common error after management fee accruals.
Management Fee Calculation Errors
Most commonly, management fees are calculated against committed capital during an investment period and against invested capital or cost basis afterwards. The timing of the end of an investment period is not always defined by a fixed date. Rather, in some LPAs, the end of the investment period is triggered by either a GP election or a portfolio metric. If a fund does not have an established process to identify and accurately capture the end of an investment period, it is common to either over-accrue or under-accrue fees until the error is noticed in the future, which is often as many as three quarters after the period ends.
A 2024 fund administrator benchmarking report found that management fees were calculated incorrectly as the primary cause of restatement among all funds under $500 million AUM (31 percent of reviewed events), and emerging managers, who have fewer back-office resources and are managing their first or second institutional vehicle, are particularly impacted. Furthermore, certain fee offset provisions, such as deal fees, monitoring fees, and director fees that are credited against management fees, add complexity that spreadsheet-based administration systems cannot adequately process as the number of investments grows. How to Handle Expense Allocations for a Limited Partnership
In order to properly reflect a limited partner's ("LP") capital account and determine the net asset value (NAV), you must make sure the fund expenses are allocated and recorded consistently. Legal fees, audit fees, organizational expenses, and deal-buster costs need to be allocated in accordance with the Limited Partnership Agreement (LPA) and recorded in every LP's capital account. It can be difficult to determine how to allocate expenses in some situations, such as when a fund has a fund-of-funds with multiple series, multiple side letters that provide expense offsets for certain limited partners, or separate co-investment vehicles that allocate deal expenses to the primary fund. If you allocate expenses incorrectly, it will have an effect on NAV. So, if a limited partner's capital account allocates 15 basis points too much in expenses in a given quarter, you have provided the LP with an incorrect performance number. If the LP is a fund of funds and is required to value its own portfolio at NAV, those NAV errors will be reported upstream from that fund manager to the next fund of funds and so forth. The SEC examination program's Private Fund Examination has listed the improper allocation of expenses by private funds among its top three findings in private fund examinations for three years in a row. As a result, LPs are now paying specific attention to expense allocation controls when performing operational due diligence.
Where Does a NAV Error Emerge During LP Due Diligence?
LPs and their consultants are becoming more systematic in how they assess a fund's administration practices. As such, it helps for the fund manager to understand the key items in due diligence because a NAV error may emerge at any one of these points.
The standard operational due diligence questionnaire, specifically the ILPA Operational Due Diligence questionnaire, has become the most commonly used by LPs and institutional allocators. This questionnaire contains questions about restatements of the NAV, the fund auditor, and the administrator. The questionnaire will ask the manager if there has been any restatement and, if you check "yes," a request for the original financials and the restated financials, the root cause of the restatement, and any remediation. If a manager can't provide an explanation to the question "Why did this occur?" along with the remediation steps that you have taken, you are at a disadvantage relative to a manager who has no restatement history. Additionally, LP audit rights are often exercised in this context. Most institutional LPAs provide the LPs the right to audit fund books; large LPs have exercised this right, according to the LPs in many more cases than many emerging fund managers realize. A 2022 Deloitte survey of institutional LP practices found that 38 percent of LPs had exercised audit rights at least once in the prior three years, up from 22 percent in the prior survey period. If a fund is audited, NAV calculation errors are likely to be found, and they can be errors that are historical in nature and have been previously corrected. This becomes the LP's institutional memory.
Steps You Can Take to Avoid NAV Errors
The solution to NAV errors is not to buy fancy software; it requires you to follow a few basic and easy steps, which the managers with clean NAV histories seem to have all done.
Have a written valuation policy, updated and reviewed once a year: The policy should specify how you determine valuation of each asset class in the portfolio, including the inputs you use and the frequency of valuation and who is responsible for the preparation and review of the valuation estimate. Even at small managers, valuation committees produce an auditable trail of how NAV was derived each period.
LPA-keyed waterfall models. The waterfall calculation model should be based directly on the LPA; each formula is to the specific section of the LPA it applies to. When the LPA is amended or an LP has received a side letter to modify the distribution terms, update the model before the next distribution, do not do it afterward.
Independent administrator reconciliation. The administrator's NAV should reconcile to the manager's records on a quarterly basis with documented sign-off before statements are released to the LP. Do not ignore reconciliation breaks, and do not post a manual entry that covers it up; identify the discrepancy and solve it.
- Written valuation policy, reviewed annually. The policy must specify the methodology for each asset class in the portfolio, the inputs used, the frequency of valuation, and who is responsible for preparing and reviewing the estimate. Valuation committees, even at small managers, create an auditable record of how NAV was determined each period.
- LPA-keyed waterfall models. The waterfall calculation model should be built directly from the LPA, with each formula tied to the specific section it implements. When the LPA is amended or an LP receives a side letter that modifies distribution terms, the model must be updated before the next distribution event — not after.
- Independent administrator reconciliation. The administrator's NAV should reconcile to the manager's internal records on a quarterly basis, with documented sign-off before statements are issued to LPs. Reconciliation breaks should be investigated and resolved, not overridden with a manual adjustment that masks the underlying discrepancy.
- Audit preparation as a year-round process. Managers who treat the annual audit as a once-a-year event consistently experience more errors than those who maintain audit-ready records throughout the year. Monthly close processes, even simplified ones, catch errors in the period they occur rather than 12 months later when the root cause is harder to trace.
The other common mistake is thinking that when the audit is done, it's correct. An audited NAV isn't the same thing as a correct NAV. Auditors have materiality thresholds. Errors smaller than the threshold still make it into the fund's audit and will also land in the LP's capital accounts. An LP that is doing their own auditing or is capital aggregating across funds, could find errors that are smaller than the threshold that the fund auditor didn't catch. Accuracy and auditability are two different standards, and LPs are increasingly making that distinction.
FAQ
FAQ
What is a NAV calculation error in a private fund?
A NAV calculation error is any discrepancy between the fund's reported net asset value and the value that would result from the correct application of the fund's valuation policy, LPA terms, and accounting standards (typically US GAAP ASC 946) to the fund's investments and cash. NAV errors may stem from improper fair value inputs, incorrect waterfalls, inaccurate fee accruals, or misallocated expenses. Each category impacts LP capital accounts differently and poses different implications for disclosure and potential restatement. What should a manager do when a NAV error is found? Act immediately and document everything. Quantify the error and explain its impact on every LP's capital account. Speak to the fund's audit firm to determine whether the error must be restated according to GAAP materiality. Notify all affected LPs with a corrected financial statement and a clear explanation of what happened and what steps have been taken to prevent a similar error in the future. Do not downplay the error in your communications to LPs. LPs who discover a coverup, lack of transparency, or a poorly explained NAV error are significantly more likely to walk away and/or decline a follow-on investment in the fund than an LP who receives a well-documented and clearly communicated correction with evidence of a control failure that has been addressed. It is more common than many managers realize. A 2024 benchmarking study found that management fee calculation errors alone represented 31 percent of restatement events at funds with less than $500 million AUM, and waterfall calculation errors appeared in 28 percent. Emerging managers lacking institutional-grade infrastructure to administer the fund, in particular, those that do not have institutional-grade administrators or that use spreadsheets for NAV calculation, have higher risk than experienced managers with established third-party fund administration.
How do LPs find out about historical NAV errors? Typically, a fund data room for the current fundraise including audited financial statements and capital account statements. LP audits under LPA audit right provisions or operational due diligence questionnaires including a specific question as to whether the fund has ever needed to restate a NAV or financial statement. A manager who proactively discloses the error, clearly communicates the cause, and identifies the steps being taken to prevent its recurrence is in a much stronger position than a manager whose error is discovered by an LP or consultant during due diligence.
Does using a third party for fund administration eliminate NAV error risk? A third-party administrator significantly reduces risk by bringing independent control mechanisms, experienced accounting professionals, and established processes designed to manage NAV complexity for private funds, but it does not remove risk. The administrator is only as good as the data and instructions provided by the manager. Managers who do not maintain clean portfolio records, do not promptly communicate LPA amendments and side letter terms, or do not review the administrator's output before sending to LPs may still experience NAV errors even under a third-party model. It is a control environment that requires both GPs and administrators.
Are NAV errors common in emerging manager funds?
They are more common than most managers realize. A 2024 benchmarking study found that 31 percent of restatement events at funds under $500 million AUM involved management fee calculation errors alone, and waterfall calculation errors appeared in 28 percent of events. Emerging managers operating without institutional-grade administration infrastructure, particularly those using spreadsheet-based processes or first-time administrators, are at elevated risk relative to managers with experienced third-party fund administrators.
How do LPs find out about historical NAV errors?
The most common disclosure points are the fund's data room during a fundraise, which typically includes audited financials and capital account statements, LP audits conducted under LPA audit rights provisions, and operational due diligence questionnaires that ask directly about restatement history. A manager who discloses an error proactively, with clear documentation of the root cause and the steps taken to prevent recurrence, is in a meaningfully stronger position than one whose error is discovered by a prospective LP during diligence.
Does using a third-party administrator eliminate NAV error risk?
A qualified third-party administrator significantly reduces the risk by adding independent controls, experienced accounting staff, and documented processes built for private fund complexity. It does not eliminate risk entirely. The administrator's work is only as accurate as the data and instructions it receives from the manager. Managers who do not maintain clean portfolio records, who do not promptly communicate LPA amendments or side letter terms, or who do not review administrator output before distribution to LPs can still experience errors under a third-party model. The control environment requires participation from both the GP and the administrator.
What should a manager do if a NAV error is discovered?
Act immediately and document everything. Quantify the error and its effect on each LP's capital account. Engage the fund's auditor to assess whether restatement is required under GAAP materiality standards. Issue corrected statements to affected LPs with a written explanation of what caused the error and what process changes prevent recurrence. Do not minimize the error in LP communications. LPs who learn about a covered-up or inadequately explained error are significantly more likely to exit or decline a re-up than LPs who receive a transparent, well-documented correction with evidence that the underlying control failure has been addressed.
