What it means
Traditional accounting records an asset at historical cost and leaves it there, gradually reduced by depreciation. Fair value accounting takes the opposite view, arguing that a portfolio of shares bought for $800,000 and now worth $1,040,000 is more usefully reported at the higher figure, because that is what the business could realise today.
Both major accounting frameworks classify fair value measurements into three levels according to how observable the inputs are. Level 1 uses quoted prices in active markets, Level 2 uses observable inputs for similar items, and Level 3 relies on the company's own models and assumptions where no market exists.
That third level is where the arguments live. When a bank values a complex instrument using its own model, the resulting number is an estimate produced by the very party whose results it flatters, which is why Level 3 assets attract close attention from auditors and analysts.
The practice is used far more widely than most non-finance managers realise. Investment portfolios, derivatives, certain biological assets, some investment property and the assets acquired in a takeover are all carried at fair value, while factories, machinery and inventory generally are not.
The most debated feature is that fair value makes reported profits move with markets. Critics argue this amplifies booms and busts, because falling prices force write-downs that trigger further selling, while supporters argue that hiding a loss in the historical cost column does not make the loss disappear.
In practice
Real-world examples.
Example
An insurance company reports a strong quarterly profit driven almost entirely by rising bond prices in its investment portfolio. Analysts strip out the revaluation gains to assess whether the underwriting business itself actually improved.
Example
A manufacturer acquires a competitor and must record the acquired brand, customer relationships and property at fair value on the acquisition date rather than at the seller's book values. The exercise takes four months and changes the reported goodwill by several million dollars.
Example
A private investment fund carries three unlisted holdings at Level 3 fair values based on internal models. Its auditor requires a written valuation memorandum for each, plus sensitivity analysis showing how the values change if the assumed growth rate falls by two percentage points.
Think of it
“Fair value accounting values things at what they're worth now-not what you originally paid.
Formula
Calculation
Unrealised Gain or Loss = (Fair Value at Reporting Date - Carrying Value Previously Recorded)
A company holds 20,000 shares in a listed supplier, purchased at $40 per share.
Original cost = 20,000 x $40 = $800,000
At the financial year end the shares trade at $52.
Fair value = 20,000 x $52 = $1,040,000
Unrealised gain = $1,040,000 - $800,000 = $240,000
The balance sheet now shows the investment at $1,040,000, and the $240,000 gain is recognised even though not a single share has been sold and no cash has moved. If the price fell to $34 the following year, fair value would be 20,000 x $34 = $680,000 and the accounts would record a loss of $1,040,000 - $680,000 = $360,000, reversing the earlier gain and more.Case study
Seen in the real world.
The following is an illustrative and fictional example. Brantmere Holdings, an invented investment company, reported profits of $9,200,000 in one year and a loss of $3,400,000 the next, while its operating subsidiaries produced almost identical cash flows in both periods. The swing came entirely from fair value movements on a portfolio of listed shares and one Level 3 property fund holding.
Shareholders complained that the accounts told them nothing about the business. In response the board restructured its reporting to show operating profit before fair value movements as the headline figure, with revaluation gains and losses presented separately underneath and the Level 3 assumptions disclosed in full.
In this fictional case nothing about the accounting standards changed, and the statutory figures were identical. What changed was that readers could see which part of the result reflected trading and which part reflected the market, which is the practical answer to most fair value complaints.
Watch out
Common mistakes.
- Reading a fair value gain as cash, when the money only exists if the asset is sold and the price holds until then.
- Assuming every balance sheet item is at fair value, when most operating assets such as plant and equipment remain at cost less depreciation.
- Treating a Level 3 valuation with the same confidence as a Level 1 quoted price, despite Level 3 depending entirely on management's own assumptions.
Questions
People also ask.
Does fair value accounting make profits more volatile?
Yes, and deliberately so, because it passes market movements through the accounts in the period they occur rather than deferring them.
Where do fair value gains actually appear?
Depending on the asset and the framework, either in profit or loss or in other comprehensive income, which is why two similar companies can present the same economics differently.
Is fair value the same as fair market value?
They are closely related, but fair value is an accounting measurement defined by the standards, while fair market value is the broader legal and tax standard used in valuations.
