What it means
The calculation is deliberately plain: add up assets, subtract liabilities, and what remains belongs to the owners. The judgement sits entirely in the valuation of the assets, since a portfolio of listed shares can be priced to the cent while a stake in a private business or a warehouse depends on an estimate.
Two funds can follow identical rules and still report different degrees of precision. For a mutual fund or unit trust, net asset value per share is not a commentary on the fund, it is the transaction price.
Orders placed during the day are settled at the value struck after the market closes, so the number determines how many shares a $10,000 investment buys. Administrators calculate it under strict controls because an error becomes a real financial loss for somebody.
Liabilities are easy to overlook but always present. Accrued management and performance fees, unsettled purchases, redemptions payable and any borrowing all reduce the figure, which is why net asset value is always lower than the headline value of the holdings.
Fees accrue daily, so the deduction happens gradually rather than in one visible charge. Outside funds, the same measure appears whenever someone wants to value a business by what it holds rather than what it earns.
Investors compare a company's market capitalisation with its net asset value to see whether the market is paying more or less than the underlying assets are worth, a comparison expressed as the price-to-book ratio. Asset-heavy sectors such as property, shipping and banking use it far more than software or services companies do.
The nuance worth carrying is that the measure only counts what appears on the balance sheet. Brands, customer relationships and internally developed technology are largely absent, so a valuable business can show a modest net asset value while a struggling one sits on substantial assets.
It answers what is owned, not what the business is worth as a going concern.
In practice
Real-world examples.
Example
A charity invests $250,000 in a bond fund priced at $25.00 per share and receives 10,000 shares. Three years later the value per share is $27.50, so the holding is worth 10,000 x $27.50 = $275,000 before any distributions received along the way.
Example
A shipping company reports total assets of $1,900,000,000 and total liabilities of $1,150,000,000, giving a net asset value of $750,000,000. Its shares trade at a total market capitalisation of $600,000,000, so investors are valuing the fleet below the accounting figure and analysts start asking whether the vessels are carried too high.
Example
A fund administrator discovers that a suspended stock was priced at its last traded value rather than a written-down estimate, overstating the value per share by $0.04 for six days. The manager reimburses investors who redeemed during that window.
Think of it
“NAV is what each share is worth-fund value divided by shares.
Formula
Calculation
Net asset value = total assets - total liabilities, and net asset value per share = net asset value / shares outstanding.
An equity fund holds securities with a market value of $540,000,000 and cash of $10,000,000, giving total assets of $550,000,000. Its liabilities are $4,000,000 of accrued management fees and $2,000,000 of trades bought but not yet settled, a total of $6,000,000. Net asset value = $550,000,000 - $6,000,000 = $544,000,000. With 40,000,000 shares in issue, net asset value per share = $544,000,000 / 40,000,000 = $13.60. An investor placing $10,000 that day receives $10,000 / $13.60 = about 735 shares, and if the portfolio later rises 5% with liabilities unchanged the value per share moves to roughly $14.28.Case study
Seen in the real world.
Marlowe Income Trust is a fictional fund used purely to illustrate the mechanics. It published a net asset value per share of $10.00 and had steadily attracted retail investors who assumed the number reflected exactly what they would receive on exit.
A wave of redemptions arrived after a market wobble, and the trust had to sell holdings quickly. Roughly 15% of the portfolio sat in less liquid corporate bonds that changed hands several points below their carrying prices, and the trust also incurred dealing costs. The next valuation came in at $9.62 per share, and investors who had redeemed earlier in the week had effectively been paid out at the expense of those who stayed.
The board introduced a swing pricing mechanism, adjusting the dealing price on heavy redemption days so that departing investors carried the trading costs they caused. In this illustrative case nothing about the accounting definition changed; what changed was recognising that a valuation and an achievable sale price are not always the same number.
Watch out
Common mistakes.
- Treating net asset value per share as the price you are guaranteed to receive. It is a valuation, and in stressed markets the cash realised on a sale can differ from it.
- Ignoring accrued fees and unsettled trades when checking a fund's figures. These liabilities are real and can move the per-share number by more than expected in a fund with performance fees.
- Assuming a company trading below its net asset value is automatically cheap. The market may simply disagree with how the assets have been valued.
Questions
People also ask.
What is the difference between net asset value and market capitalisation?
One is what the balance sheet says the assets are worth after debts, the other is what investors are collectively paying for the shares today.
Is net asset value the same as book value?
For a company the two are effectively the same idea, though book value tends to use historic cost while fund reporting uses current market values.
How does a distribution affect the value per share?
It reduces it by the amount paid out, because cash leaves the fund, so total return must combine the change in value per share with the distributions received.
