How Transaction Costs Work in Fair Value Measurement

Under both ASC 820 and IFRS 13, transaction costs are excluded from fair value measurement. The reported fair value is the gross exit price in the principal or most advantageous market, with no deduction for brokerage commissions, legal fees, transfer taxes, or similar charges.¹ The logic is that these costs describe the deal, not the asset. Two entities holding the same security should report the same fair value even if one negotiated cheaper brokerage. Transaction costs still matter in the analysis, but only for selecting the market and for how the expense flows through the income statement.

What Counts as a Transaction Cost

Both frameworks define transaction costs as the incremental direct costs to sell an asset or transfer a liability in the principal or most advantageous market. A cost qualifies only if it meets two tests: it results directly from and is essential to the transaction, and the entity would not have incurred it if it had decided not to sell.² Brokerage commissions, attorney fees for drafting closing documents, stamp duties, and government transfer taxes all clear that bar.

Costs that fail the test include internal overhead, portfolio management fees, ongoing due diligence expenses, and administrative costs not tied to the specific disposal. Misclassifying one of these as a transaction cost can distort both market selection and the pattern of expense recognition, so the two-part test does real work.

Transport costs sit outside the definition entirely. Moving an asset to the market where it will be sold is carved out and handled under separate rules discussed below.¹

Why Transaction Costs Do Not Reduce Fair Value

Both standards state the rule plainly: the price in the principal or most advantageous market used to measure fair value “shall not be adjusted for transaction costs.”² Transaction costs are a characteristic of the transaction, not of the asset or liability. Different entities pay different fees based on size, broker relationships, or negotiating leverage, and pulling those costs into fair value would let two companies holding identical assets report different numbers.

A quick example. If a publicly traded stock has a quoted price of $100 and a $2 brokerage commission applies to sell it, fair value is $100. The $2 is a cost of transacting, not a reduction in what the market says the stock is worth.¹

Where Transaction Costs Do Matter: Choosing the Market

Fair value measurement starts by identifying the principal market, meaning the one with the greatest volume and level of activity for the asset or liability. An entity does not have to canvas every possible venue. It must consider information that is reasonably available, and absent evidence to the contrary it can presume that the market where it normally transacts is the principal market.¹

When no principal market exists, the entity turns to the most advantageous market. This is where transaction costs enter the analysis. The entity compares net proceeds across candidate markets by subtracting each market’s transaction costs from its sale price, and picks the market that produces the highest net figure. A venue offering a higher gross price can lose to one with lower fees.

Then comes the turn that catches preparers. Once the most advantageous market is selected, the transaction costs used to select it are stripped back out. The fair value recorded on the balance sheet is the gross price in that market, not the net amount the entity would pocket. Transaction costs are a selection tool, not a measurement adjustment.

Transport Costs Are Different

Transport costs can reduce fair value even though transaction costs cannot. The dividing line is whether location is a characteristic of the asset. For physical commodities like crude oil, grain, or precious metals, prices vary by geography. A barrel of oil sitting at a remote wellhead is worth less than the same barrel at a pipeline hub, and that difference belongs to the asset itself.

When location qualifies as a characteristic, the entity adjusts the market price by subtracting the costs that would be incurred to move the asset from its current location to the principal or most advantageous market.² For nonfinancial assets like machinery, the analysis can also include installation costs when the asset’s value depends on being configured for use in a particular place.¹ Transport costs behave more like a pricing input than an expense. The distance discount lives inside fair value; the commissions and legal fees required to sell do not.

Blockage Factors Follow the Same Logic

Entities holding a large position in a single security sometimes want to discount the quoted price to reflect the fact that selling the whole block at once would move the market. That discount, called a blockage factor, is prohibited for Level 1 measurements.

If a quoted price exists in an active market, the entity must use it without adjustment, even if normal daily trading volume could not absorb the full position in a single trade. Fair value equals the quoted price multiplied by the quantity held.² The blockage factor is a characteristic of the entity’s holding rather than of the asset, which puts it in the same conceptual bucket as transaction costs. Both describe the seller’s situation, and both are excluded to protect comparability. An entity may end up reporting a fair value that overstates what it could realistically fetch in a single trade, and the standards accept that outcome.

When the Transaction Price Is Not Fair Value at Initial Recognition

The price paid to acquire an asset (the transaction price) usually equals its fair value at initial recognition, but not always. Both standards flag specific situations where a gap can appear:

Related-party transactions, where the price may not reflect arm’s-length terms.
Transactions under duress, where a distressed seller accepts a below-market price.
Different units of account, such as a business combination that bundles multiple elements or a price that includes embedded transaction costs or unstated rights.
Different markets, where the entry transaction occurs in a market other than the principal or most advantageous market for exit.

The third bullet is where transaction costs directly produce a day-one gap. When the price paid includes an embedded fee, such as a structuring charge on a derivative, that fee is not part of the asset’s fair value. The entity separates the fee and recognizes it as an expense at inception.¹

Under IFRS 13, if another standard requires initial measurement at fair value and the transaction price differs from fair value, the resulting gain or loss is recognized in profit or loss unless that other standard specifies otherwise.² For financial instruments under IFRS 9, day-one differences are often deferred rather than recognized immediately, and the deferred balance unwinds over the instrument’s life. When the transaction price is accepted as fair value at inception and subsequent measurement uses a valuation model with unobservable inputs, the entity must calibrate that model so its initial output matches the transaction price. Without calibration, an artificial gain could appear the day after acquisition.

How Transaction Costs Flow Through the Financial Statements

Because transaction costs are excluded from the asset’s measured value, they do not increase the carrying amount on the balance sheet. When an entity sells an asset measured at fair value through earnings, the transaction costs are recognized as an expense in the period the transaction occurs. They are not capitalized into the asset’s basis, and doing so would inflate reported values in a way the standards prohibit.¹ For items subsequently measured at fair value with changes in earnings, transaction costs hit the income statement when incurred. They represent a separate economic event from holding the asset.

Tax Treatment Runs on a Different Track

The tax mechanics differ from the book mechanics, and the gap trips people up. For U.S. federal income tax purposes, selling expenses such as brokerage commissions, attorney fees, and deed preparation fees are not expensed separately. They reduce the “amount realized” from the sale, which in turn reduces the taxable gain or increases the recognized loss.³ Transfer taxes and stamp taxes paid by the seller also count as selling expenses for this purpose.⁴

The end direction is the same, lower proceeds and lower tax, but the mechanics diverge. Under GAAP, the fair value stays gross and the costs are expensed. On the tax return, the selling price itself is reduced by the costs before gain or loss is calculated. Entities disposing of assets carried at fair value need to track both treatments.
