Net asset value (NAV) accuracy has moved beyond the finance function and operational credibility to a critical agenda item for boards.
Investors, auditors and regulators increasingly judge firms not only by the numbers they report, but by how confidently senior leaders can explain them.
This reflects the environment firms operate in. Fund structures are more complex, markets more volatile and NAV is no longer a figure that simply closes the books. It informs decisions around liquidity, performance and capital allocation, which means any weakness in the underlying process carries wider commercial consequences.
Investor expectations and the need to maintain confidence reinforce this pressure. In March 2025, the Financial Conduct Authority (FCA) indicated that robust valuation practices are important for fairness and confidence in private markets, particularly where assets lack frequent trading and regular price discovery. This makes NAV accuracy more than a reporting issue. It is central to investor trust and the firm’s ability to defend its numbers under scrutiny.
NAV errors cause significant damage that boards should understand
What many firms’ leadership teams still underestimate is the true cost of getting NAV wrong. The damage does not end with the correction, because once an error surfaces it can trigger delayed reporting, investor queries, heavier audit scrutiny and, in some cases, reputational damage.
That is why a NAV error should rarely be dismissed as a one-off mistake. In most cases, the visible miscalculation is simply the point at which a weak control environment becomes impossible to ignore.
The underlying weaknesses are usually familiar. Data is fragmented across multiple systems; manual intervention happens at critical points in the process and calculation logic is applied inconsistently. Controls exist, but too often they depend on post-event review rather than being embedded directly into the workflow.
Once that kind of environment takes hold, inconsistent inputs, offline adjustments and ungoverned changes can move through the process unnoticed until the consequences are harder, and more expensive, to contain.
Misplaced confidence is common
Unaware of what lies beneath the surface, a firm’s board can feel more comfortable than it should. Confidence in the NAV process often comes from familiarity rather than robustness, particularly when reporting is delivered on time and experienced individuals are overseeing the work.
Yet that apparent control can rest on spreadsheet-based adjustments, manual reconciliations and knowledge concentrated in a small number of people. Those conditions may seem manageable when volumes are stable, but they quickly expose how fragile the process is when the business needs to scale, adapt or respond to detailed challenge.
Control needs to be built into the operating model
That is why control over data and calculations matters. Real control means a clear, auditable flow from source data to the final NAV, with calculation logic applied consistently through a centralised engine, changes traceable back to their origin and controls embedded within the process. It also means teams can drill into a number quickly and explain it without launching a lengthy investigation across multiple systems and side files.
The value of that control is often understated because it is still viewed too narrowly through a compliance lens. Auditors and regulators care about traceability, of course, but the operational case is just as important. When a team cannot explain a figure immediately, time is diverted into investigation and rework, senior leaders are pulled into remediation activity and the wider organisation shifts into a reactive mode that absorbs energy without creating value.
A purpose-built accounting model resolves inconsistencies early
A modern, purpose-built accounting environment changes that dynamic by removing much of the dependence on stitching together outputs from disconnected systems and spreadsheets at the end of the process.
Firms that have moved their accounting environment to a single trusted foundation are better placed to answer investor questions in minutes, not days.
However, the benefit is not simply faster processing. It is the ability to produce figures that are more transparent and easier to defend under pressure, instead of relying on effort and memory to hold the process together.
Relying on final checks to spot unreliable NAV is not advisable
For that reason, boards should be wary of letting their teams treat NAV risk as a problem that can be solved by adding further checks at the end. Additional review may catch individual issues, but it does little to remove the conditions that allow those issues to arise in the first place.
The more effective response is to redesign the operating model so that accuracy is built in from the outset, through controlled data and infrastructure that reflect how the business actually runs.
The most useful test for boards wanting to maintain good investor relations remains a simple one. If an investor challenged any number in the NAV today, how quickly and how confidently could the business explain it?
That question gets to the heart of the issue. Today, accurate, controlled accounting does more than satisfy a technical requirement. It protects investor confidence and gives boards greater protection and confidence when scrutiny intensifies. This is why, in a market that leaves little room for error, it should be viewed as a genuine competitive advantage.
