The relative fair value of an individual element and thus the revenue recog- nized for this unit of accounting, however, is limited by that proportion of the total arrangement consideration to be provided by the customer, the payment of which does not depend on the delivery of additional elements. If the fair value of the delivered elements cannot be determined reliably but the fair value of the undelivered elements can be determined reliably, the total arrangement consideration provided by the customer is allocated by determining the fair value of the delivered elements as the difference between the total arrangement consideration and the fair value of the undelivered elements. Payments to customers, including payments to dealers and agents (discounts, provisions) are generally recognized as a decrease in revenue. If the consideration provides a benefit in its own right and can be reliably measured, the payments are recognized as expenses. Revenue from systems integration contracts requiring the delivery of customized products is recognized by reference to the stage of completion, as determined by the ratio of project costs incurred to date to estimated total contract costs, with estimates regularly revised during the life of the con- tract. A group of contracts, whether with a single customer or with several customers, is treated as a single contract when the group of contracts is negotiated as a single package, the contracts are closely interrelated and the contracts are performed concurrently or in a continuous sequence. When a contract covers a number of assets, the construction of each asset is treated separately when separate proposals have been submitted for each asset, each asset has been negotiated separately and can be accepted or rejected by the customer separately, and the costs and revenues of each asset can be identified. Receivables from these contracts are classified in the item “trade and other receivables” in the statement of financial position. Receivables from these contracts are calculated as the balance of the costs incurred and the profits recognized, less any discounts and recognized losses on the contract; if the balance for a contract is negative, this amount is reported in liabilities. If the total actual and estimated expenses exceed revenues for a particular contract, the loss is immediately recognized.
