Provided that estimates are made on a reasonable basis, then the amounts taken to
profit or loss in each year, in accordance with IAS11, will reflect the underlying
position – which is that profits are earned over the life of the construction contract,
not on the date that the contract is finally completed.
However, IAS 11 also applies the following requirements.
Revenue and costs can only be recognised when the outcome of a contract can be
estimated reliably.
If a contract is expected to make a loss, the whole of the loss must be recognised
immediately.
These requirements apply the concept of prudence and help to ensure that the
information in the financial statements is reliable.
IAS 11 appears to be at odds with the ‘accounting equation’ approach adopted by
the IASB Framework and other accounting standards, in which equity is the
difference between assets and liabilities, and profit for the year is the increase in
equity (assuming no dividend payments, no share issues and no upward asset
revaluations). IAS 11 takes a different view of the accounting process, in which
transactions are matched to accounting periods and assets and liabilities are the
amounts ‘left over’.
2.3 Recognising revenue and costs of a contract in the financial statements
The following rules apply to the recognition of the revenue and costs for a
construction contract in the financial statements of the contractor.
Contract revenue
Contract revenue is the amount payable by the customer. IAS 11 defines it as:
the initial amount of revenue agreed in the contract; plus
variations in contract work, claims and incentive payments (provided that these
will probably result in revenue and can be reliably measured).
All of the contract price, or a large part of it, may be a fixed amount (= a price
agreed in the terms of the contract). Provided that the outcome of the contract can
be estimated reliably, revenue is taken to profit or loss as the contract progresses.
This is sometimes called the percentage of completion method of accounting for
construction contracts.
Determining the stage of completion of a contract
There are several possible methods of measuring the stage (percentage) of
completion of a contract.
Use the percentage of total contract costs incurred to date (sometimes called the
costs basis). This is the more common method in examination questions.
Use surveys of work performed (sometimes called the sales basis). As a contract
progresses, at periodic intervals, an independent expert such as a surveyor may
inspect the work, and issue a certificate stating the amount or value of the work
done so far. The most recent certificate issued by the independent expert
