The document discusses International Accounting Standard 11 (IAS 11) which provides guidance on accounting for construction contracts. IAS 11 addresses how to recognize revenue and expenses over time for long-term construction projects. It requires using the percentage of completion method to recognize revenue and profit as a project progresses, unless the outcome cannot be reliably estimated, in which case equal amounts of revenue and expense are recognized. The standard also provides guidance on combining and segmenting contracts, measuring contract revenue and costs, and disclosures required in financial statements.
