Net Asset Value (NAV)

Because an investment company's assets and liabilities change daily, NAV also changes daily, and it is this daily fluctuation — rather than any secondary market supply and demand — that determines the price at which open-end mutual fund investors buy and sell shares.

The Formula and Its Components

NAV per share equals total assets minus total liabilities divided by shares outstanding.

Total assets comprise the market value of all securities held in the portfolio — priced at their closing market prices on the calculation date — plus cash and cash equivalents, accrued dividends and interest receivable, and any other assets belonging to the fund. 

For a fund holding one hundred equity positions, total assets on any given day reflect the closing prices of all one hundred positions that day plus any uninvested cash.

Total liabilities include accrued management fees payable to the investment adviser, accrued administrative and operational expenses, pending dividend and capital gain distributions payable to shareholders, and any other short-term obligations of the fund. 

The distinction between accrued and paid expenses matters because expenses reduce NAV daily as they accrue rather than only when cash is actually disbursed.

A worked example illustrates the calculation precisely. A fund holds securities valued at two hundred million dollars at the close of markets on a given day. It holds five million dollars in cash. It has accrued but unpaid management fees of three hundred thousand dollars and other liabilities of two hundred thousand dollars. Total assets are two hundred and five million dollars. 

Total liabilities are five hundred thousand dollars. Net assets are two hundred and four million five hundred thousand dollars. With ten million shares outstanding, NAV per share is twenty dollars and forty-five cents.

The Regulatory Framework — Investment Company Act of 1940

The statutory and regulatory provisions governing NAV calculation are established under the Investment Company Act of 1940 and the rules adopted thereunder, as confirmed by the SEC's investor.gov NAV definition. The three most relevant provisions are Section 2(a)(41), which defines value for purposes of the Act, Rule 2a-4, which specifies how funds must calculate net asset value per share, and Rule 22c-1, which governs the pricing of redeemable securities.

Section 2(a)(41) of the Investment Company Act defines value as the market value of portfolio securities for which market quotations are readily available, and fair value determined in good faith by the board of directors for all other securities. 

This definition establishes the hierarchy between observable market prices and board-determined fair values that governs portfolio valuation under GAAP and investment company law simultaneously.

Rule 2a-4 requires that an open-end management company — a mutual fund — compute its current NAV per share by totalling the current market value of all assets, subtracting all liabilities, and dividing by the total number of outstanding shares. The rule requires that NAV be calculated at least once each business day and specifies that securities for which market quotations are readily available must be valued at their current market price.

Rule 22c-1 — the forward pricing rule — is the most examination-critical provision and the one most directly tested on securities licensing examinations. 

The rule prohibits any registered investment company from selling or redeeming its redeemable securities at a price other than the current NAV next computed after the order is received. 

This forward pricing requirement means that investors who submit orders to buy or sell mutual fund shares receive the NAV calculated at the close of the trading day on which the order is received — not the NAV that was in effect when the order was submitted and not the NAV from the prior day. 

Orders received before four PM Eastern Time on a business day receive that day's closing NAV. Orders received after four PM receive the following business day's closing NAV.

The purpose of the forward pricing rule, as explained in the SEC's 2003 amendments release, is to prevent late trading abuse — the practice of submitting orders after market close while receiving that day's already-known closing prices, which allows traders to profit at the expense of long-term fund shareholders by exploiting price information unavailable at the time the order should have been submitted.

NAV in Open-End Mutual Funds — Price Equals NAV

For open-end mutual funds, NAV is simultaneously the price at which shares are issued and the price at which they are redeemed — there is no separate market price. When an investor purchases mutual fund shares, new shares are created and the investor pays NAV plus any applicable front-end sales load. When an investor redeems shares, shares are cancelled and the investor receives NAV minus any applicable redemption fee or contingent deferred sales charge.

This identity between NAV and transaction price means that mutual fund shares cannot trade at a premium or discount to NAV — unlike closed-end funds and ETFs. An investor buying mutual fund shares always pays precisely NAV plus sales load, and always receives precisely NAV minus any redemption charges. The NAV is not a reference price or a benchmark — it is the actual transaction price.

The public offering price for load funds equals NAV divided by one minus the front-end load percentage. For a fund with an NAV of twenty dollars and a five percent front-end load, the public offering price is twenty dollars divided by one minus five percent, equalling twenty dollars divided by zero point ninety-five, equalling approximately twenty-one dollars and five cents. The difference between the public offering price and NAV is the sales load — the compensation paid to the selling broker-dealer.

The relationship between NAV, public offering price, and the sales load is directly tested on Series 7 examinations. Candidates must be able to calculate any one of these three figures when given the other two.

NAV in ETFs — The Arbitrage Mechanism

Exchange-traded funds calculate NAV daily at the close of markets, but unlike mutual funds their shares trade continuously on exchanges throughout the trading day at market prices that may differ from the underlying portfolio NAV. The mechanism that prevents large or sustained deviations between an ETF's market price and its NAV is the arbitrage activity of authorised participants — large institutional broker-dealers with the ability to create and redeem ETF shares directly with the fund in large blocks called creation units.

When an ETF's market price rises above its NAV — when it trades at a premium — authorised participants can profit by purchasing the underlying basket of securities, delivering them to the ETF in exchange for newly created ETF shares, and immediately selling those shares in the market at the premium price. 

This selling pressure on the ETF price and buying pressure on the underlying securities drives both prices back toward convergence. 

When an ETF's market price falls below its NAV — when it trades at a discount — authorised participants can buy ETF shares in the market at the discounted price and redeem them for the underlying basket of securities worth NAV, profiting from the difference. This arbitrage mechanism keeps most ETF market prices very close to NAV under normal market conditions.

ETFs also publish an intraday indicative value — updated every fifteen seconds throughout the trading day — that estimates the current NAV based on real-time prices of the underlying holdings. This intraday estimate provides investors with a current reference for assessing whether the ETF market price represents a premium or discount to the estimated current portfolio value.

Unlike mutual fund shares, ETF shares can be bought on margin and sold short because they trade as exchange-listed securities rather than as primary market direct transactions with the fund. ETFs may also be purchased and sold at any point during trading hours at market or limit prices, providing intraday liquidity unavailable to mutual fund investors who must submit orders before four PM for same-day execution at the closing NAV.

NAV in Closed-End Funds — The Premium and Discount

Closed-end funds issue a fixed number of shares in an initial public offering and list those shares for secondary market trading on a national exchange. Because shares are not continuously created or redeemed at NAV — shareholders must sell to other investors rather than redeeming directly with the fund — the market price of closed-end fund shares may diverge substantially from the fund's NAV.

When a closed-end fund's market price exceeds its NAV, it trades at a premium — investors are paying more for the fund shares than the underlying portfolio is worth. When the market price is below NAV, it trades at a discount — investors can acquire the underlying portfolio for less than its calculated value. Discounts and premiums on closed-end funds are expressed as a percentage of NAV: a fund with a twenty dollar NAV trading at eighteen dollars trades at a ten percent discount. A fund trading at twenty-two dollars trades at a ten percent premium.

Persistent discounts to NAV are among the most interesting phenomena in investment management — they represent a situation where owning a closed-end fund provides access to the underlying portfolio at below its appraised value. This discount may persist because investors price in the fund's ongoing management fees, concerns about the quality of the manager's portfolio valuation assumptions, liquidity constraints of the fund's holdings, or simply investor preference for open-end vehicles.

NAV in REITs — A Different Application

For real estate investment trusts, NAV represents the estimated market value of the REIT's real property portfolio minus any outstanding debt and other liabilities, divided by shares outstanding — providing a property-value based per-share estimate that can be compared to the REIT's current trading price to assess whether the REIT is trading at a premium or discount to its underlying real estate value.

Non-traded REITs — REITs that do not list their shares on national exchanges — report NAV periodically through independent appraisals of their property portfolios, providing the primary basis on which their shares are valued for secondary market transactions and redemption programs. The NAV of a non-traded REIT may be reported only quarterly or annually, making it substantially less timely than the daily NAV calculations required for registered investment companies.

Examination Relevance and Key Takeaways

NAV is tested on the SIE, Series 7, and Series 65 examinations in the context of mutual fund pricing, the forward pricing rule, the distinction between open-end and closed-end funds, and ETF arbitrage mechanics.

The key points to retain are these.

NAV equals total assets minus total liabilities divided by shares outstanding, calculated at least once each business day for open-end mutual funds under Rule 2a-4 under the Investment Company Act of 1940. The statutory definition of value is in Section 2(a)(41) — market value for quoted securities, fair value determined in good faith by the board for others. The forward pricing rule under SEC Rule 22c-1 requires that purchase and redemption orders be executed at the NAV next computed after the order is received — investors always receive the next NAV, not the current one. 

The four PM Eastern Time cutoff determines whether an order receives that day's or the following day's NAV. For open-end mutual funds, NAV is the transaction price — shares cannot trade at a premium or discount to NAV because they are continuously created and redeemed at NAV directly with the fund. 

The public offering price for load fund Class A shares equals NAV divided by one minus the load percentage. For ETFs, shares trade at market prices throughout the day that may differ from NAV, with authorised participants conducting arbitrage to keep market prices close to NAV through the creation and redemption mechanism. 

For closed-end funds, market prices reflect supply and demand and may trade at persistent premiums or discounts to NAV because shares are traded between investors rather than redeemed with the fund. NAV should not be used as a performance measure in isolation because distributions reduce NAV even when they represent income earned — total return including distributions is the correct performance metric.
