IAS 18 was the international accounting standard that told a business when it could record revenue. The core test for goods was whether the seller had transferred the significant risks and rewards of ownership to the buyer; services were recognized as work progressed; and interest, royalties, and dividends each had their own trigger tied to the economic substance of the arrangement. IAS 18 revenue recognition applied until IFRS 15 replaced the standard for reporting periods beginning on or after 1 January 2018, so it still governs how any pre-2018 financial statements were built.
The Five Conditions for Recognizing Revenue on Sold Goods
Paragraph 14 of the standard set five conditions, and all of them had to be met before any revenue from a sale could hit the income statement. Miss one, and the whole amount waited.
- The significant risks and rewards of ownership had passed to the buyer.
- The seller retained neither managerial involvement to the degree usually associated with ownership nor effective control over the goods.
- The revenue could be measured reliably.
- It was probable that the economic benefits of the transaction would flow to the seller.
- The costs incurred, or still to be incurred, could be measured reliably.
The first two carried most of the weight. They pushed preparers to look at the substance of a deal rather than its paperwork. A signed contract meant nothing if the seller still bore the risk of damage, obsolescence, or unsold stock. The remaining three kept the numbers honest: no revenue booked on figures nobody could pin down, and no revenue booked without matching costs.
Where the Rule Got Tricky: Common Scenarios
Real transactions rarely lined up cleanly with the five conditions. The appendix to IAS 18 worked through several arrangements that came up often.
Sales With a Right of Return
The question here was whether the seller could reliably estimate how many goods would come back. If not, risks and rewards had not really passed, and revenue was deferred entirely until the return window closed.
With enough historical data to make a reliable estimate, the seller recognized revenue for what it expected to keep. On a $100,000 sale with $5,000 in expected returns, it recorded $95,000 immediately and carried the $5,000 as a liability. The cost of goods tied to the deferred $5,000 was held back too, so the income statement stayed matched.
Sales With Installation or Inspection
Take a $50,000 machinery sale where payment is conditional on successful installation and formal buyer sign-off. Until installation is finished and the buyer accepts, the seller still carries the risk of something going wrong, and revenue is deferred.
There was an exception. If installation was simple and routine and the buyer had already assumed the main risks of loss or damage, the seller could recognize revenue on delivery and accrue the cost of the remaining installation work as an expense. The line turned on whether the installation was substantive or a formality.
Consignment Sales
A manufacturer ships inventory to a retailer, but the retailer only pays once the goods sell to an end customer. The retailer is acting as an agent, not a buyer. The manufacturer still bears the risks of theft, damage, and obsolescence while goods sit on the retailer’s shelves.1IFRS Foundation. IAS 18 Revenue – Guidance on Identifying Agency Arrangements
No revenue is recorded when goods leave the manufacturer. Revenue is recognized only when the retailer sells to the final customer, because that is when risks and rewards actually move.
Sale With a Repurchase Agreement
A seller transfers goods for $100,000 and agrees to buy them back for $105,000 in six months. That looks like a sale but functions like a loan secured by the inventory, with the $5,000 difference acting as interest. Because the seller is obligated to take the goods back at a predetermined price, the significant risks and rewards never left.
No sale revenue is booked. The $100,000 received is recorded as a liability, the $5,000 premium as interest expense spread over the six months, and the inventory stays on the seller’s balance sheet. IAS 18 and IFRS 15 both reach the same answer on this: when the repurchase price equals or exceeds the original price, the transaction is financing, not sale.2IFRS Foundation. IASB Agenda Ref 7B – Revenue Recognition Repurchase Agreements
Principal or Agent: Gross Revenue or Net Commission
Whether an entity acted as a principal or as an agent changed how much revenue appeared on its income statement. A principal reported the full amount received from the customer. An agent reported only the commission or fee it earned. Amounts collected on behalf of a principal were not the agent’s revenue at all.1IFRS Foundation. IAS 18 Revenue – Guidance on Identifying Agency Arrangements
The analysis came back to whether the entity had ever been exposed to the primary risks and rewards of owning the goods. Four practical indicators helped frame it:
- Does the entity bear inventory risk before a customer orders or after a customer returns goods?
- Does the entity have latitude to set the selling price?
- Is the entity the party the customer holds responsible for delivering the goods or services?
- Does the entity choose which supplier fulfills the order?
An online marketplace that never takes possession, cannot set prices, and just connects buyers and sellers is almost always an agent, recording only its fee. A wholesaler that buys inventory, warehouses it, sets its markup, and eats the loss on unsold stock is a principal, recording the full sale. Cases in between required judgment, and auditors scrutinized those conclusions closely.
Barter and Non-Monetary Exchanges
IAS 18 separated two kinds of non-cash swaps. When goods or services of a similar nature and value were exchanged, no revenue arose. Commodity markets were the standard illustration: oil suppliers routinely swap inventory between locations to serve local demand, and those swaps do not create income because both sides end up with essentially the same thing.3IFRS Foundation. IAS 18 Revenue
When dissimilar goods or services were exchanged, revenue was generated. It was measured at the fair value of whatever was received. If that fair value could not be pinned down reliably, the fair value of what was given up was used instead, adjusted for any cash that changed hands. A media company trading advertising space for consulting work would measure revenue at the fair value of the consulting services received.3IFRS Foundation. IAS 18 Revenue
Revenue From Services
Services did not have a single point-in-time recognition event. IAS 18 used the percentage-of-completion method: revenue was booked in proportion to the work done. That only worked when the outcome of the transaction could be estimated reliably, which required four conditions:3IFRS Foundation. IAS 18 Revenue
- The revenue could be measured reliably.
- Economic benefits would probably flow to the entity.
- The stage of completion at the reporting date could be measured reliably.
- The costs incurred and the costs to complete could be measured reliably.
A 12-month maintenance contract sold for $1,200 with an even delivery pattern generates $100 of revenue per month. The $1,200 collected upfront sits as deferred revenue and shrinks by $100 each month as service is rendered.
A time-and-materials support contract billed at $150 per hour has no set total or endpoint, so percentage of completion does not apply. Revenue is recognized as each hour of work is performed: 10 hours of work equals $1,500 of revenue.
When the outcome genuinely could not be estimated, IAS 18 allowed revenue only to the extent of recoverable costs already incurred. Expenses were matched by an equal amount of revenue, so the entity showed zero profit on the work rather than an anticipated gain or an artificial loss. Once the uncertainty cleared, the entity switched to percentage-of-completion going forward.3IFRS Foundation. IAS 18 Revenue
Interest, Royalties, and Dividends
IAS 18 also covered income earned by letting others use the entity’s assets, and each category had its own trigger.
Interest was recognized using the effective interest method, which applies a constant rate of return to the carrying amount of the financial asset over its life. Income tracks the outstanding balance and the passage of time, not the timing of cash receipts.
Royalties were recognized on an accrual basis following the substance of the agreement. A 5% royalty on quarterly sales was booked as those sales occurred, regardless of when the licensor was paid.
Dividends were recognized when the shareholder’s right to receive payment was established. In practice, that meant the date the investee formally declared the dividend. Before declaration, there was no legal entitlement and no revenue.
Disclosure Requirements
Paragraph 35 required entities to disclose:
- The accounting policies adopted for recognizing revenue, including the methods used to determine the stage of completion of service transactions.
- The amount of revenue recognized in each major category: sale of goods, rendering of services, interest, royalties, and dividends.
- Within each of those categories, the amount of revenue arising from exchanges of goods or services.
The barter line mattered because a reader would otherwise have no way to separate cash-generating revenue from non-monetary swaps, which affects any judgment about liquidity.
What Changed Under IFRS 15
IFRS 15 replaced IAS 18, IAS 11 on construction contracts, and several related interpretations for reporting periods beginning on or after 1 January 2018. The framework moved from risks-and-rewards to control: revenue is recognized when the customer obtains control of the good or service, meaning the customer can direct its use and receive substantially all of its remaining benefits. A five-step model applies to every revenue contract, requiring the entity to identify the contract, identify the performance obligations, determine the transaction price, allocate that price across the obligations, and recognize revenue as each obligation is satisfied.4IFRS. IFRS 15 Revenue from Contracts with Customers
For a retailer selling goods over the counter, IAS 18 and IFRS 15 usually reach the same result. For contracts with licenses, variable pricing, or bundled goods and services, the new standard forces a much more granular analysis, and the timing or amount of revenue can differ meaningfully from the old treatment. Anyone comparing financial statements that straddle the changeover needs both frameworks in mind to read the numbers correctly.
