Have You Ever Faced These Challenges?
- Your contracts include volume rebates or performance bonuses, and you are unsure how much of that variable consideration you are permitted to include in the transaction price at any given reporting date
- You applied the constraint too conservatively — recognising little or no variable consideration — and then had to record a large cumulative catch-up adjustment when the uncertainty resolved

The Purpose of Step 3: Determining How Much Revenue to Recognise
Steps 1 and 2 establish that a contract exists and identify what the entity has promised to deliver. Step 3 asks a different question: how much consideration is the entity entitled to receive in exchange for those promises?
The answer is not always straightforward. Many commercial contracts include elements that make the total consideration uncertain at inception — rebates tied to purchase volumes, bonuses contingent on performance milestones, rights of return, or payment structures that span multiple years. IFRS 15 provides a framework for dealing with each of these, but applying that framework requires significant judgement.
The transaction price is defined as the amount of consideration to which an entity expects to be entitled in exchange for transferring promised goods or services to a customer (IFRS 15.47). Two aspects of this definition deserve emphasis. First, it is based on expectation, not certainty. Second, amounts collected on behalf of third parties — such as consumption taxes or sales taxes — are excluded.
The Four Components of the Transaction Price
IFRS 15 identifies four factors that may affect the transaction price:
| Factor | Frequency in practice |
|---|---|
| Variable consideration | Very high |
| Significant financing component | Moderate |
| Non-cash consideration | Low |
| Consideration payable to a customer | Moderate |
Variable consideration is by far the most commonly encountered and the most technically demanding. The remainder of this article focuses primarily on variable consideration, with shorter treatments of the other three components.
Variable Consideration
What Constitutes Variable Consideration?
Consideration is variable when the amount to which the entity will ultimately be entitled depends on the occurrence or non-occurrence of a future event. Common examples include:
- Volume rebates: A customer receives a retrospective discount if cumulative purchases exceed a specified threshold during the contract period
- Performance bonuses: Additional consideration is payable if the entity completes a project ahead of schedule or achieves specified quality metrics
- Penalties: The consideration is reduced if the entity fails to meet defined service levels or delivery timelines
- Rights of return: The customer may return products within a specified period, reducing the net consideration received
- Price protection clauses: The contract price is adjusted retrospectively if the entity offers lower prices to other customers within a defined period
Step 1: Estimating the Amount of Variable Consideration
Variable consideration must be estimated using one of two methods (IFRS 15.53). The choice of method should reflect whichever approach better predicts the amount of consideration to which the entity will be entitled.
Method 1 — Expected Value
The expected value is the probability-weighted average of all possible outcomes. This method is most appropriate where the contract has a large number of possible outcomes, or where the entity has a portfolio of similar contracts from which statistical patterns can be derived.
Worked example:
An entity sells goods to a distributor under a contract that includes a year-end volume rebate. The rebate structure is as follows:
| Annual purchase volume | Rebate rate | Rebate amount | Probability |
|---|---|---|---|
| Below ¥50 million | 0% | ¥0 | 20% |
| ¥50m – ¥80m | 3% | ¥1.8m (on ¥60m mid-point) | 50% |
| Above ¥80m | 5% | ¥4.5m (on ¥90m mid-point) | 30% |
Expected value = (¥0 × 20%) + (¥1.8m × 50%) + (¥4.5m × 30%) = ¥2.25 million
The entity deducts ¥2.25 million from the transaction price as estimated variable consideration, recognising a corresponding refund liability.
Method 2 — Most Likely Amount
The most likely amount is the single most probable outcome from the range of possible outcomes. This method is most appropriate where the outcome is binary — either a specified event occurs or it does not.
Worked example:
An entity is constructing a facility under a contract that includes a completion bonus of ¥5 million if the project is delivered by a specified date. Based on current progress and historical performance on similar projects, management assesses that on-time completion is highly probable.
The most likely amount is ¥5 million, and this amount is included in the transaction price — subject to the constraint discussed below.
Step 2: Applying the Constraint on Variable Consideration
Estimating the amount of variable consideration is only the first step. The estimated amount is included in the transaction price only to the extent that it is highly probable that a significant reversal of cumulative recognised revenue will not occur when the uncertainty is subsequently resolved (IFRS 15.56).
This is known as the constraint on variable consideration, and it is one of the most judgement-intensive requirements in IFRS 15.
IFRS 15.57 identifies five factors that increase the likelihood of a significant revenue reversal — and therefore indicate that the constraint should be applied more conservatively:
- The amount of consideration is highly susceptible to factors outside the entity’s influence — market prices, weather conditions, third-party actions, or the outcome of legal proceedings
- The uncertainty is not expected to be resolved for a long period of time
- The entity has limited experience with similar contracts, or that experience has limited predictive value
- The contract has a broad range of possible consideration amounts
- The contract has a large number of possible consideration outcomes with a wide range of variability
Practical implication: Where these factors are present, the entity should include only the amount of variable consideration for which it is highly probable that no significant reversal will occur — which may be substantially less than the expected value or most likely amount calculated in Step 1.
The two most common errors in practice:
Over-constraint: Recognising zero variable consideration on the grounds that any estimate is uncertain. This results in an artificially depressed transaction price and a large cumulative catch-up adjustment when the uncertainty resolves — producing revenue volatility that IFRS 15 was designed to prevent.
Under-constraint: Including variable consideration in the transaction price based on an optimistic estimate without adequate consideration of the reversal risk. This results in revenue that must subsequently be reversed, again producing volatility and potential restatement.
The appropriate approach is to estimate variable consideration carefully, apply the constraint rigorously, and document both the estimate and the constraint assessment with sufficient evidence to withstand audit scrutiny.
Accounting for Rights of Return
Where a contract grants the customer a right to return a product, the entity recognises revenue only for the consideration to which it expects to be entitled — that is, the consideration associated with products that are not expected to be returned (IFRS 15.B21).
The accounting entries at the point of sale are:
- Revenue: Recognised for the portion of products not expected to be returned
- Refund liability: Recognised for the consideration associated with expected returns
- Return asset: Recognised for the carrying amount of the products expected to be returned (representing the entity’s right to recover the goods)
The refund liability and return asset are updated at each reporting date as estimates of expected returns are revised.
Estimating return rates: Where the entity has an established track record with similar products and customer segments, historical return rates provide the most reliable basis for estimation. For new products or customer relationships without relevant historical data, management must exercise greater judgement, drawing on industry data, market research, and the characteristics of the specific products and customers involved.
Significant Financing Component
When Does a Significant Financing Component Exist?
A significant financing component exists when the timing of payments agreed upon in the contract provides either the customer or the entity with a significant benefit of financing (IFRS 15.60).
This arises in two broad scenarios:
- The customer pays significantly in advance of receiving the goods or services (e.g., a large deposit on a multi-year real estate development)
- The customer pays significantly after receiving the goods or services (e.g., a long-term instalment arrangement for capital equipment)
In both cases, the economic substance is that one party is financing the other. IFRS 15 requires the transaction price to be adjusted to reflect what the cash selling price would have been — the financing element is separated and recognised as interest income or interest expense over the financing period.
The One-Year Practical Expedient
As a practical expedient, an entity need not adjust the transaction price for the effects of a significant financing component if the entity expects, at contract inception, that the period between the transfer of the promised goods or services and the customer payment will be one year or less (IFRS 15.63).
This expedient is widely applied in practice and eliminates the need for financing adjustments in the majority of commercial transactions.
Several points of caution apply:
- The one-year period is measured from the later of the transfer of goods or services and the payment date — not from contract inception
- The expedient applies to the expected timing at contract inception, not to the actual timing if circumstances change
- Instalment arrangements where the primary purpose is credit risk management (protecting the entity against default) rather than financing may not give rise to a significant financing component, even where the payment period exceeds one year
Determining the Discount Rate
Where a significant financing component exists, the discount rate used to adjust the transaction price should reflect the rate that would apply if the entity and the customer entered into a separate financing arrangement with similar terms and credit characteristics (IFRS 15.64). This rate is determined at contract inception and is not updated for subsequent changes in interest rates or the customer’s credit profile.
Non-Cash Consideration
Where a customer pays with non-cash consideration — such as equity instruments, goods, or services — the consideration is measured at fair value at contract inception (IFRS 15.66). Where fair value cannot be reasonably estimated, the consideration is measured by reference to the standalone selling price of the goods or services transferred by the entity.
Consideration Payable to a Customer
Where an entity pays consideration to a customer — for example, slotting fees paid to a retailer for product placement, or marketing development funds provided to a distributor — the payment is treated as a reduction of the transaction price unless it represents payment for a distinct good or service received from the customer (IFRS 15.70).
For a payment to qualify as consideration for a distinct good or service, the entity must be able to identify what it is receiving, and the fair value of what it is receiving must be measurable. In many cases, payments described commercially as “promotional support” or “cooperative marketing” do not meet this threshold and must therefore reduce revenue rather than be recognised as a marketing expense.
This distinction has significant P&L implications, particularly for consumer goods manufacturers and distributors operating through retail channels.
Comparison with Japanese GAAP
| Area | IFRS 15 | Japanese GAAP (ASBJ No. 29) |
|---|---|---|
| Variable consideration estimation | Required | Same |
| Constraint on variable consideration | Required | Same |
| Significant financing component | Required with one-year expedient | Same |
| Consideration payable to customer | Revenue reduction unless for distinct service | Same, with some additional guidance |
The frameworks are substantially aligned. The primary practical differences arise in the application of certain simplifications available under Japanese GAAP that are not permitted under IFRS 15.
Summary
The key takeaways from Step 3 are as follows:
- Variable consideration must be estimated using either the expected value method (for contracts with multiple possible outcomes) or the most likely amount method (for binary outcomes)
- The estimated amount is included in the transaction price only to the extent that it is highly probable a significant revenue reversal will not occur — the constraint requires active judgement, not conservative inaction
- The most common errors are over-constraint (recognising zero variable consideration) and under-constraint (including amounts without adequate reversal risk assessment)
- Rights of return give rise to a refund liability and a return asset, not simply a deferral of revenue
- A significant financing component adjustment is required where the payment interval exceeds one year and the primary purpose is financing rather than credit risk management
- Consideration payable to customers reduces revenue unless it is payment for a distinct, measurable service received
