What it means
The calculation itself is simple subtraction: assets minus liabilities. What makes NAV useful is the valuation discipline behind it, because assets are marked at current market value rather than at what was originally paid.
That is the difference between NAV and a plain balance sheet figure based on historic cost. For open-ended funds NAV is not just a report, it is the dealing price.
Investors buy in and cash out at the NAV struck at the next valuation point, which is usually the end of each trading day, so the number decides exactly how much money changes hands. This is why fund administrators treat the daily NAV run as a controlled process with sign-offs and error tolerances.
In private equity, venture capital, property funds and infrastructure the assets have no live market price, so NAV depends on valuation judgement. Managers use comparable company multiples, recent transactions, discounted cash flows and independent appraisals, and they typically report quarterly rather than daily.
Investors therefore look at both the reported NAV and the assumptions sitting underneath it. NAV also anchors a family of other measures.
Performance is often quoted as the change in NAV per share plus distributions, listed vehicles trade at a premium or discount to NAV, and lenders size facilities against it. Once you can read a NAV statement you can follow most of the reporting an investment manager sends out.
The nuance to hold on to is timing and staleness. A daily NAV based on liquid shares is close to reality, while a quarterly private markets NAV reflects valuations that may be several months old, especially where the manager waits for audited accounts from portfolio companies.
Comparing the two as if they carried equal precision is the most common analytical error.
In practice
Real-world examples.
Example
A pension scheme redeems 200,000 units of a bond fund. The administrator strikes the NAV at the close of business at $12.40 per unit, so the scheme receives 200,000 x $12.40 = $2,480,000 less any exit charge.
Example
A listed infrastructure trust reports NAV per share of $2.05 while its shares trade at $1.80. Analysts describe it as trading at a 12% discount to NAV and debate whether the market doubts the valuations or simply wants a liquidity cushion.
Example
A venture fund's quarterly report shows NAV falling from $310,000,000 to $268,000,000 after two portfolio companies raise money at lower valuations. Limited partners use the new NAV to update their own reporting even though no shares were sold.
Think of it
“NAV is the abbreviation for Net Asset Value-per share value of the fund.
Formula
Calculation
NAV = total assets - total liabilities, and NAV per unit = NAV / units outstanding.
An investment fund holds listed shares and bonds worth $845,000,000 plus $15,000,000 of cash, giving total assets of $860,000,000. It owes $35,000,000 in accrued management fees, unsettled purchases and a small credit facility. NAV = $860,000,000 - $35,000,000 = $825,000,000. With 25,000,000 units in issue, NAV per unit = $825,000,000 / 25,000,000 = $33.00. If the portfolio then rises by $16,500,000 with liabilities unchanged, NAV becomes $841,500,000 and NAV per unit = $841,500,000 / 25,000,000 = $33.66, a gain of $0.66 per unit or 2%.Case study
Seen in the real world.
Brackenmoor Capital is a fictional mid-sized asset manager invented for this illustrative example. It ran two products: a daily-dealing equity fund and a closed-ended property vehicle, and it reported NAV for both on the same monthly investor letter.
Investors began asking why the property NAV barely moved during a quarter when listed property shares fell sharply. The answer was mechanical rather than sinister: the property assets were valued by external surveyors twice a year, so the reported NAV still carried valuations struck several months earlier, while the equity fund repriced every evening.
Brackenmoor changed its disclosure to show the valuation date next to every NAV figure and moved the property vehicle to quarterly external valuations. Nothing about the underlying assets changed, but investors could finally see how fresh each number was. The illustrative point is that a NAV is only as current as the last valuation behind it.
Watch out
Common mistakes.
- Reading NAV as a market price. For a listed vehicle the traded share price and NAV per share are two different numbers, and the gap between them is itself information.
- Comparing a daily NAV and a quarterly private markets NAV as equally precise. One is struck from live prices, the other from periodic estimates.
- Forgetting to deduct accrued fees and unsettled trades. These are genuine liabilities, and leaving them out overstates NAV in a way that eventually has to be corrected.
Questions
People also ask.
How often is NAV calculated?
Daily for most open-ended funds, monthly or quarterly for private equity, credit and property vehicles, depending on how the assets are valued.
Does a rising NAV always mean the manager performed well?
Not necessarily, because distributions reduce NAV and new subscriptions increase it, so performance is measured per unit and after allowing for cash flows.
What is a NAV error?
It is a mispriced dealing point, and where the error exceeds the fund's tolerance the manager normally has to compensate the affected investors.
