Whats the accounting treatment of IAS 11 construction contracts?

Some construction contracts are completed with in some months. They start in an accounting year and complete in the same year. So no issue arises about the recognition of revenue and expenses of the contract as both of them will be recognized in the same year. But in accounting life we see that many construction contracts take more than one year to complete or they start in one year and complete in the next one. In these circumstances an issue arises about the recognition of revenue and cost of the contracts. This issue has been resolved by IAS 11. Although IAS 11 is not too difficult but it still contains some technical and detailed concepts. Summary of IAS 11 is prepared in a way that it contains all the important and critical concepts of IAS 11 in a concise way. It is very important for students for revision purpose.
