What it means
Historical cost accounting records an asset at what was paid for it and leaves it there, which can be badly out of date. Fair value instead asks what the asset could be sold for now.
This matters most for financial instruments such as shares, bonds and derivatives, as well as for investment property and assets acquired in a business combination. Accounting standards describe fair value as an exit price, meaning the amount received to sell an asset or paid to transfer a liability.
It assumes an orderly deal between informed buyers and sellers, not a forced sale at a distressed price. The aim is a neutral, market-based measurement rather than the opinion of management.
To keep measurement disciplined, standards use a three-level hierarchy. Level 1 uses quoted prices for identical assets in active markets, such as a listed share.
Level 2 uses observable inputs for similar items, and Level 3 relies on unobservable inputs and internal models, such as a discounted cash flow valuation of a private business. The higher the level number, the more judgement is involved, so analysts pay close attention to Level 3 assets.
Companies must disclose how much of their fair value measurement relies on each level, which tells readers how much of the reported number is observable and how much is estimated. Changes in fair value are recognised either in profit or loss or in other comprehensive income, depending on the type of asset and the accounting rules that apply.
This can make earnings more volatile, because market movements flow through to reported results. Supporters argue the transparency is worth the volatility, while critics point to the risk of unreliable estimates in thin markets.
Fair value also applies to liabilities and to business acquisitions. When one company buys another, it must measure the assets and liabilities it takes on at fair value, and any amount paid above that total is recorded as goodwill.
This is why deal accounting often requires valuation specialists and careful assumptions.
In practice
Real-world examples
Example 1
A fund holds a portfolio of listed company shares worth $12,000,000 on the last trading day of the year. It reports the holding at that market price because a quoted price is the best evidence of fair value. No judgement is needed because the price is observable and verifiable.
Example 2
A property company owns an office building that it values each year using recent sales of similar buildings and rental income. The valuation moves up by $2,000,000, and the gain is reported in the income statement. Because the inputs are estimates, the valuation is classified as Level 2 or Level 3.
Example 3
A technology group buys a start-up and must record the acquired customer list at fair value. It engages a specialist who forecasts future cash flows from the customers and discounts them to arrive at $3,500,000. Any price paid above the total of such fair values would be recorded as goodwill.
Think of it
Fair value is like the price your car would sell for today if you put it on the market, not what you originally paid.
Formula
Calculation
Fair value gain or loss = Fair value at period end - Carrying amount at start
Quarry Ventures, a fictional company, holds shares bought for $500,000, which it values at fair value through profit or loss. At the year end the shares trade on an exchange at a market value of $560,000, a Level 1 measurement. The gain is $560,000 - $500,000 = $60,000, which is recognised in the income statement. If the shares fall to $470,000 the next year, the loss is $470,000 - $560,000 = -$90,000.Case study
Seen in the real world
Pinecrest Holdings is an illustrative, fictional investment company that held a minority stake in a private software business. For two years it carried the stake at its original cost of $2,000,000.
When a new investor bought into the software business at a valuation implying that Pinecrest's stake was worth $3,200,000, the auditors insisted that the carrying amount be updated. The change created a gain of $1,200,000 that lifted that year's profit.
In the illustrative discussion that followed, Pinecrest's board realised the gain was unrealised, meaning no cash had changed hands. They added a clear note to their results explaining the valuation method, and the finance team separated the fair value gain when presenting underlying operating performance. The finance team also tested the sensitivity of the value to the assumptions used, so that readers could see the range rather than a single number.
Watch out
Common mistakes
- Assuming fair value always equals market price, when for assets without active markets it is an estimate from a model.
- Treating a fair value gain as cash profit, when it is unrealised until the asset is sold.
- Using a distressed or forced-sale price as fair value, when the definition assumes an orderly transaction.
Questions
People also ask
What is the difference between fair value and book value?
Book value is the recorded accounting figure, often based on historical cost, while fair value reflects current market conditions.
What are the three levels of the fair value hierarchy?
Level 1 uses quoted prices, Level 2 uses observable inputs and Level 3 uses unobservable inputs and judgement.
Why does fair value accounting create volatility?
Because changes in market prices flow into reported results each period, profits can swing even when operations are steady.
