Every pooled fund needs one number that connects the entire portfolio to one investor share. That number is net asset value.
NAV begins with the fund’s assets. It subtracts liabilities. It then divides the residual net assets across the fund shares or units that participate in that value.
Simple arithmetic sits on top of difficult work: security prices, foreign exchange, accrued income, expenses, fair-value estimates, corporate actions, timing cut-offs, share creation, redemption and data quality.
This article is part of Batch 035 of the eduKateSG Finance Authority 400. Mutual Funds owns the pooled-fund structure. Exchange-Traded Funds owns exchange trading and creation/redemption. This page owns the fund accounting value beneath both structures.
NAV is where the fund proves how much underlying net value one share is supposed to represent.
Educational boundary: valuation policies, pricing points, fair-value rules, dealing cut-offs and error-correction procedures vary by jurisdiction and fund. This article explains the mechanism rather than a fund-specific accounting policy.
The short answer: what is NAV?
Net asset value is the value of a fund’s assets minus its liabilities. NAV per share is that net amount divided by the relevant fund shares outstanding.
NAV = TOTAL ASSETS − TOTAL LIABILITIES.
NAV PER SHARE = NAV ÷ FUND SHARES OUTSTANDING.
Investor.gov explains that mutual fund purchases and redemptions are generally based on the next calculated NAV, while ETF shares can trade at market prices above or below NAV. See Investor.gov’s Mutual Funds guide and the ETF investor bulletin.
NAV is a balance sheet for one fund share
A conventional company balance sheet reports assets, liabilities and equity.
A fund’s NAV performs a similar residual calculation for the pooled investment vehicle.
Imagine a fund owns:
- S$70 million of shares;
- S$25 million of bonds;
- S$6 million of cash and receivables.
It owes S$1 million of accrued expenses and other liabilities.
Total net assets are S$100 million.
If 10 million fund shares participate equally, NAV is S$10 per share.
Assets are more than securities
A fund’s asset side can include more than quoted shares and bonds.
- cash;
- accrued interest;
- dividends receivable;
- sale proceeds not yet settled;
- derivative receivables;
- foreign currencies;
- other permitted investments.
The exact categories depend on the vehicle and strategy.
NAV therefore starts with a complete fund-level balance sheet, not merely the visible list of portfolio holdings.
Liabilities reduce the value belonging to fund shareholders
Fund liabilities can include:
- management fees accrued but not yet paid;
- custody or administration expenses;
- payables for securities purchased;
- derivative liabilities;
- borrowings where permitted;
- distributions payable;
- other fund expenses.
A fund can own S$100 million of investments and still have NAV below S$100 million if liabilities are sitting against those assets.
The asset number alone overstates what belongs to investors.
NAV per share needs the correct denominator
Suppose net assets are S$100 million.
At 10 million shares, NAV is S$10.
At 20 million shares, NAV is S$5.
The underlying net assets are identical. The measuring unit changed.
This is why fund share splits do not automatically create or destroy wealth. They can change units while leaving proportional ownership unchanged.
Subscriptions can increase assets and shares together
Return to the S$100 million fund with 10 million shares and S$10 NAV.
A new investor contributes S$5 million at S$10, ignoring fees and valuation movement.
The fund issues 500,000 shares.
Net assets become S$105 million. Shares become 10.5 million. NAV remains S$10.
New share issuance is not automatically dilutive because matching assets entered the fund.
The earlier Share Dilution article owns the wider denominator logic.
Redemptions reduce assets and shares together
If an investor redeems 500,000 shares at S$10, the fund pays S$5 million and cancels those shares under the simplified example.
Net assets fall from S$105 million back to S$100 million.
Shares fall from 10.5 million to 10 million.
NAV remains S$10.
Again, this assumes the fund can raise the cash without imposing unallocated trading costs on the remaining investors.
NAV changes when portfolio value changes
Suppose the fund still has 10 million shares but its portfolio assets rise by S$8 million while liabilities remain unchanged.
NAV rises from S$100 million to S$108 million.
NAV per share rises from S$10 to S$10.80.
This is the most direct route from underlying portfolio performance into the investor’s fund-share value.
Distributions move value out of NAV
If a fund distributes S$0.50 per share to 10 million shareholders, S$5 million leaves the vehicle.
All else equal, NAV falls by approximately S$0.50 per share.
The SEC’s 2026 Fund Distributions bulletin explains that distributions reduce a fund’s NAV.
This prevents double counting: cash moved from the fund to the investor. It did not appear from nowhere.
The valuation point creates a timestamp
NAV is calculated at a specified valuation point.
Market prices move continuously across the world.
A fund must decide which prices, exchange rates, accrued amounts and fair values belong to the NAV timestamp.
This means NAV should always be read with a date and time.
A NAV from yesterday afternoon is not a current mark after a major overnight market event.
Forward pricing protects against known-order arbitrage
Conventional mutual funds generally use forward pricing: an order placed before the applicable cut-off receives the next calculated NAV rather than a previously known NAV.
The logic is important.
If investors could place orders after seeing today’s market close but transact at yesterday’s known NAV, they could exploit stale fund pricing at the expense of existing shareholders.
Forward pricing links the transaction to a valuation not yet known when the order is accepted.
Listed securities can be easy to price—and still need policy
A listed share might have:
- a last traded price;
- a closing auction price;
- a bid and ask;
- no trade near the valuation time;
- a halted market;
- an exchange in another time zone.
The fund’s valuation policy needs to determine which source is appropriate under different conditions.
“Listed” does not remove the need for valuation judgement.
Illiquid securities require fair-value judgement
A private security or thinly traded bond may have no reliable current market transaction.
The fund can then need a fair-value process using models, comparable securities, pricing services or other inputs under the applicable framework.
This creates model risk.
A reported NAV can be carefully calculated and still contain uncertain asset values.
Wintour v1.0 requires that distinction to remain visible: reported valuation and directly observable market price are not the same evidence class.
Stale pricing can transfer wealth between entering and exiting investors
Suppose a foreign security is recorded at S$10 based on a closed market.
New information strongly suggests it would reopen near S$8.
If the fund allows redemption at a NAV still using S$10, exiting investors can receive too much relative to the economic value of the asset, leaving the loss with investors who remain.
Fair-value adjustments are designed to reduce that transfer under the applicable policy.
The purpose is not to predict tomorrow perfectly. It is to avoid knowingly using an obsolete price when material evidence shows it no longer represents fair value.
Foreign exchange is part of NAV
A global fund can own securities in multiple currencies.
To calculate NAV in the fund’s base currency, those assets and liabilities need to be translated using the fund’s chosen FX valuation source and timing convention.
A portfolio can be unchanged in local-currency terms while NAV moves because the exchange rate moved.
Currency exposure therefore reaches fund investors through NAV even when no security price changed in its home market.
Accrued income increases NAV before cash arrives
A bond can earn interest each day even though the coupon is paid only twice a year.
A dividend can become receivable before the cash reaches the fund.
Fund accounting therefore includes accruals.
This is the pooled-investment version of the earlier Accrual vs Cash Accounting distinction.
NAV can rise before the related cash is received because the fund has acquired an economic claim.
Accrued expenses reduce NAV before cash leaves
Likewise, management and administration expenses can accrue through time before their cash payment date.
If a fund waits until fee-payment day to recognise the entire cost, NAV would be overstated between payments.
Accrual spreads the recognised obligation across the period in which the service is received under the applicable accounting approach.
Different share classes can have different NAVs
A single portfolio can support multiple fund share classes.
If the classes bear different expenses, currencies or distribution policies, their NAV per share can diverge over time even though they participate in the same underlying portfolio.
A hedged currency class can also have derivative gains, losses and hedging costs that differ from an unhedged class.
“Same fund” therefore does not always mean “same NAV per share.”
Equalisation and income accounting can complicate distributions
When investors enter a fund shortly before a distribution, part of the NAV they pay can reflect income already accumulated inside the fund.
Different fund systems use accounting methods to distinguish income earned before and after entry and to manage distribution fairness.
The precise rules vary.
The economic principle is stable: distribution accounting should not create a hidden transfer merely because investors entered at different points in the income cycle.
NAV can be correct while the investor cannot realise it instantly
A fund can calculate NAV at S$10 while holding assets that would be difficult to liquidate immediately at those values.
NAV is an accounting valuation under the fund’s policies.
Liquidity asks another question: what cash could actually be raised, at what cost, and how quickly?
During calm markets the two can sit close.
During stress they can diverge sharply.
ETF market price can differ from NAV
ETF shares trade intraday.
Official NAV is calculated under a fund valuation process.
The two numbers can differ because:
- market demand for ETF shares changes;
- underlying markets are closed;
- basket execution costs rise;
- portfolio values are stale;
- arbitrage becomes expensive;
- trading occurs between official valuation points.
The preceding ETF article owns the premium/discount and creation-redemption mechanism.
NAV is not intrinsic value
A fund’s NAV can be calculated perfectly and the underlying portfolio can still be overvalued in an economic sense.
If a fund owns a listed share at S$100 and the market price is S$100, the NAV normally uses that market evidence according to policy.
That does not prove the company is fundamentally worth S$100 per share.
NAV reports the fund’s value using its valuation framework. The earlier Price vs Value article retains the fundamental-value boundary.
Pricing errors are operational risk
A wrong security price, stale FX rate, missing liability or incorrect share count can produce the wrong NAV.
That can cause investors to subscribe or redeem at an incorrect price.
The error then becomes a fairness and remediation problem: who gained, who lost, how large was the difference and what correction is required under the fund’s rules?
Fund accounting therefore requires controls, reconciliations and independent checks—not just formulas.
Corporate actions change portfolio quantities
A stock split changes share count and unit price.
A rights issue creates entitlements.
A merger replaces one security with another.
A dividend creates cash or a receivable.
If the accounting system misses the corporate action, NAV can be wrong even when market prices are correct.
NAV is therefore a record-keeping system as much as a valuation system.
Settlement timing can create receivables and payables
A fund can sell a security today and receive cash later under the market’s settlement cycle.
The sold security no longer belongs to the portfolio after the relevant accounting recognition, but a receivable from the counterparty can replace it.
Likewise, a purchase can create a payable before cash settles.
This is another reason NAV is not merely “sum today’s holdings.” It is the complete economic position of the fund at the valuation time.
Swing pricing changes the transaction NAV for anti-dilution purposes
Some fund regimes allow swing pricing, where the transaction price is adjusted when net subscriptions or redemptions cross defined conditions, so estimated portfolio-trading costs are allocated more directly to transacting investors.
This creates a distinction between:
- the unswung portfolio NAV;
- the adjusted dealing NAV used for subscriptions or redemptions under the mechanism.
The purpose is not to change the fund’s economic assets magically. It is to protect remaining investors from bearing costs caused by large flows.
NAV and leverage
A leveraged fund can have assets substantially larger than NAV because liabilities finance part of the portfolio.
Suppose assets are S$150 million and liabilities are S$50 million.
NAV is S$100 million.
If asset values fall 10% to S$135 million while liabilities stay S$50 million, NAV falls to S$85 million—a 15% decline.
The leverage amplifies the loss to fund equity.
NAV therefore carries the same residual-claim mathematics described earlier in Assets, Liabilities and Equity.
Worked NAV bridge
| Fund item | Beginning | Ending | Change |
|---|---|---|---|
| Equity holdings | S$60m | S$64m | +S$4m |
| Bond holdings | S$30m | S$29m | −S$1m |
| Cash / receivables | S$12m | S$14m | +S$2m |
| Liabilities | S$2m | S$2.5m | +S$0.5m liability |
| Net assets | S$100m | S$104.5m | +S$4.5m |
| Fund shares | 10m | 10.2m | +0.2m |
| NAV/share | S$10.00 | ≈S$10.245 | ≈+2.45% |
The net assets rose 4.5%, but NAV per share rose only about 2.45% because the fund also issued additional shares for incoming capital.
That is not evidence of dilution by itself. The corresponding subscription assets are inside the ending net assets.
Failure-first reading: what can make NAV misleading?
- Underlying prices are stale.
- Illiquid holdings rely on optimistic models.
- FX rates are inconsistent with the valuation timestamp.
- Corporate actions are missing.
- Liabilities or accrued expenses are understated.
- Share counts are wrong.
- Large redemptions impose costs not reflected in transacting prices.
- Market price is mistaken for NAV—or NAV for directly realisable cash value.
NAV is trustworthy when the data, valuation policy, timing, liabilities and denominator are trustworthy.
The NAV diagnostic
- What assets are included?
- What liabilities are deducted?
- What valuation time applies?
- Which prices are directly observed?
- Which assets are fair-valued?
- What FX rates are used?
- What income and expenses are accrued?
- What share count is used?
- Do different share classes have separate NAVs?
- How do subscriptions and redemptions affect the calculation?
- How are trading costs allocated?
- How are distributions reflected?
- For ETFs, how far is market price from NAV?
- What operational controls catch pricing errors?
Observable mastery test
An ETF has official NAV S$25 and trades at S$24.50. A reader says, “The NAV proves the ETF is worth S$25 and can be sold there.”
The correction is that NAV is the fund’s calculated net asset value under its valuation policy. The retail investor sells ETF shares at market prices, not automatically at NAV. The S$0.50 gap may reflect true discount, stale underlying prices, transaction costs or market stress.
You understand NAV when you can identify the accounting value, the transaction price and the liquidity route separately.
The World Return: NAV as the fund’s reconciliation layer
Underlying assets and liabilities → valuation and accrual → fund NAV → investor dealing or market comparison → subscriptions / redemptions / trading → portfolio flows → underlying assets again.
NAV is the reconciliation layer that keeps the pooled fund attached to the assets underneath.
Without a credible NAV process, mutual-fund dealing becomes unfair and ETF arbitrage loses its reference point.
The number is powerful because it compresses the whole fund balance sheet into one share. It remains only as trustworthy as the evidence that built it.
