Introduction to IAS 11 and Its Purpose
International Accounting Standard 11, commonly abbreviated as IAS 11, was designed to guide how companies report revenue and related costs for construction projects that span more than one accounting period. Construction activities often stretch across months or years, which makes it difficult to match income with expenses in a standard annual reporting cycle. The standard addressed this challenge by outlining when and how revenue should be recorded in line with work performed rather than simply when cash is received.
Under this standard, the emphasis was on reflecting the true economic activity of construction projects by linking revenue and expenses to the level of work completed at any point in time. This was intended to prevent large distortions in company financial results that might occur if long-term projects were only recognized upon final completion. By encouraging a more realistic timing of recognition, IAS 11 sought to improve comparability, transparency and reliability of financial information presented by companies engaged in construction and similar long-term production activities.
Historical Development and Replacement by IFRS 15
The evolution of IAS 11 spans several decades. Early guidance began in the late 1970s, when exposure drafts were released to gather feedback from industry practitioners and regulators. In 1979, the first official version of IAS 11 was issued, providing early direction for accounting in the construction sector. Later, a revised version was issued in 1993, aligned with a broader initiative aimed at improving comparability of financial statements internationally.
Despite its long-standing role, IAS 11 was eventually replaced. Effective January 2018, IAS 11 was superseded by IFRS 15, a more comprehensive standard on revenue recognition. IFRS 15 introduced new principles that applied across industries and offered a unified approach to recognizing revenue from contracts with customers. Still, understanding IAS 11 remains important for historical reference and interpretation of past financial statements, especially when analyzing older contracts or comparing performance across periods that were governed by the earlier standard.
The Nature and Scope of Construction Contracts
The standard applied to contracts that involved the creation of an asset or a collection of assets that were closely connected to each other. Construction could include buildings, bridges, infrastructure, or specialized equipment assembled according to unique customer specifications. The key concept was that the agreement had been specifically negotiated between contractor and client, meaning that the contract terms were tailored rather than applying generic or mass-produced arrangements.
In situations where a single contract involved multiple components or assets, specific rules guided whether the agreement should be treated as one combined arrangement or separated into distinct portions. If separate negotiations took place for each asset or if pricing and measurement were independently determined, each component might be accounted for individually. In contrast, if assets were strongly interrelated or negotiated as a package, they would typically be recognized as part of a unified contract. Similarly, optional additional work could be treated as a separate contract if the extra construction differed substantially from the original project or if its price was separately agreed upon.
Components of Contract Revenue
Contract revenue under IAS 11 was broader than the initial price written into the agreement. It could also include adjustments for changes in project scope, such as approved modifications to design or materials, provided these adjustments were likely to be recovered and could be measured with reasonable certainty. Claims for compensation due to delays or additional work could also form part of contract revenue, again subject to reasonable measurement and recoverability.
Some construction contracts also included incentive payments for completing work ahead of schedule, achieving quality benchmarks, or meeting defined performance conditions. In such cases, the expected value of these incentives was incorporated into revenue recognition if the contractor could reliably assess the probability of receiving these amounts. The goal was to capture the economic reality of the contract rather than a simple total based only on the original signed agreement.
Elements of Contract Costs
Contract costs did not only involve direct construction expenses. They also included indirect costs that could be attributed to the project, such as expenses arising from general construction operations, materials management, site overheads and sometimes project-related administrative functions. Expenses that could be charged to the customer under the contract terms, including certain allocated overheads or reimbursable amounts, were also included.
Costs that related specifically to securing the contract or preparing the site could be included if they could be directly linked to the contract and were recoverable. These detailed rules attempted to ensure that all relevant expenses were fairly reflected in determining the financial performance of a construction project, reducing the risk that contractors might misstate the profitability of long-term work.
Revenue Recognition Through the Percentage of Completion Method
A central principle of IAS 11 was the percentage of completion approach. Rather than waiting until the project ended, revenue and related expenses were recognized gradually as work progressed and value was delivered. This approach required companies to estimate the total revenue of the contract, predict future costs, and determine the extent to which the project had been completed at the reporting date. Methods for estimating completion varied, ranging from surveys of work performed, comparison of actual to estimated costs, or physical measurement of progress.
This method aimed to closely match income with the associated expenses, producing a more accurate representation of economic activity over time. It also provided users of financial statements with more relevant insight into how ongoing projects contributed to company performance. If the outcome of a contract could be reliably measured, profit could be recognized progressively.
When Outcomes Were Uncertain
There were situations in which the contractor was unable to reliably estimate the ultimate outcome of a project. In such circumstances, IAS 11 required a more cautious approach. Revenue was recognized only to the extent that costs were expected to be recovered, and costs were expensed as incurred. No profit could be reported until sufficient certainty existed about the project outcome. This prevented premature recognition of income before sufficient evidence supported the final economic result.
Additionally, if a loss on a contract was expected, IAS 11 required immediate recognition of that loss. This reflected the principle that anticipated losses should not be deferred, and financial statements must portray economic reality even if the news was unfavorable.
Presentation and Disclosure
IAS 11 provided detailed guidance on financial statement presentation. When construction in progress resulted in amounts due from customers, this was shown as an asset. Conversely, if customers had paid more than the recognized revenue or if billing outpaced recognized value, a liability was recorded. This approach illustrated whether the contractor was effectively working ahead of customer payments or, alternatively, receiving funds before delivering the corresponding work.
Disclosures included information on revenue recognized during the period, the methods used to measure stage of completion, and the techniques applied to determine revenue. Additional disclosures highlighted total costs incurred to date, recognized profit, amounts billed, advances received, and retentions, ensuring that stakeholders could understand the status of contracts that remained open at the reporting date.
Final Thoughts
Although IAS 11 is no longer the current standard, it played an important role in shaping modern revenue recognition principles in the construction industry. It introduced systematic and transparent methods for dealing with long-term contracts, creating a foundation upon which IFRS 15 later built a more unified revenue framework across industries. Understanding IAS 11 remains valuable for interpreting historical financial information and appreciating the evolution of accounting standards in the context of complex, multi-period business activities.
Frequently Asked Questions
What is the main purpose of IAS 11?
IAS 11 explains how to record revenue and costs for long-term construction projects so that income is shown based on actual work completed rather than only when cash is received.
Why was IAS 11 developed for construction activities?
Construction projects often last several years, so normal yearly reporting does not properly match income and expenses. IAS 11 created a method to spread revenue over the life of the project.
What type of contracts fall under IAS 11?
It applies to contracts specifically negotiated for building or creating assets, such as houses, roads, or infrastructure, where the customer and contractor agree on custom work.
When can a contract be divided into separate parts?
If each part was negotiated separately, priced separately, and measured separately, then each section can be treated as its own contract.
How are changes and variations treated?
Approved changes in design or extra work can be added to contract revenue if the contractor expects to recover these amounts and they can be measured reliably.
What is included in contract costs?
Costs directly linked to the project, plus indirect costs that can be reasonably allocated, and any additional expenses that the contract allows the contractor to charge to the customer.
How does IAS 11 recognize revenue over time?
Revenue is recognized using the percentage of completion method, which matches work performed with the stage of progress rather than waiting for project completion.
How is the stage of completion determined?
Progress can be measured using surveys, physical completion levels, or comparing costs incurred to estimated total costs.
What happens when the project outcome cannot be estimated reliably?
Revenue is limited to the amount expected to be recovered, and costs are recorded immediately without recognizing profit until the outcome becomes more certain.
What if a loss is expected on a project?
Any anticipated loss must be recognized immediately rather than waiting until later periods.
How are amounts due from customers shown in the financial statements?
If work done exceeds billings, the difference appears as an asset because the contractor is owed money for completed work.
What do companies need to disclose under IAS 11?
They must disclose contract revenue recognized, methods for measuring progress, total costs incurred, recognized profit, advances, and any retention amounts.
