5. Segment information

The segment information contained in this note makes reference to several non-GAAP financial measures, definitions for which can be found in note 4.

5.1 Accounting policy

(a) Revenue recognition

Revenue comprises the fair value of the consideration received or receivable for goods supplied and services rendered to customers after deducting rebates, discounts and value-added taxes, and after eliminating sales within the Group. Revenue from the sale of goods is recognised when persuasive evidence exists, usually in the form of an executed sales agreement, that the significant risks and rewards of ownership have been transferred to the customer, recovery of the consideration is probable, there is no continuing management involvement with the goods, and the amount of revenue can be measured reliably. A provision for anticipated returns is made based primarily on historical return rates. Where a contractual arrangement consists of two or more separate elements that can be provided to customers either on a stand-alone basis or as an extra, such as the provision of supplementary materials with equipment, revenue is recognised for each element as if it were an individual contractual arrangement.

(b) Research and development costs

Expenditure on research activities is recognised in the income statement as an expense in the year in which it is incurred. Expenditure on development activities is capitalised if the product or process is technically and commercially feasible and the Group has sufficient resources to complete development. All other development expenditure is recognised in the income statement as an expense in the year in which it is incurred. Capitalised development expenditure is stated at cost less accumulated amortisation and impairment losses.

5.2 Business segments

Operating segments for continuing operations

For reporting purposes, the Group is organised into two main business segments: Steel and Foundry and the senior executive management of each of these business segments reports to the Chief Executive of the Group. It is the Vesuvius Board which makes the key operating decisions in respect of these segments. The information used by the Vesuvius Board to review performance and determine resource allocation between the business segments is presented with the Group's activities segmented between the two business segments, Steel and Foundry. Taking into account the basis on which the Group's activities are reported to the Vesuvius Board, the Directors believe that these two business segments are the appropriate way to analyse the Group's results. The principal activities of each of these segments are described in the Operating Review.

Segment revenue represents revenue from external customers (inter-segment revenue is not material). Trading profit includes items directly attributable to a segment as well as those items that can be allocated on a reasonable basis.

Discontinued operations

Discontinued operations in 2012 include the results of the Alent group of companies for the period up to 19 December 2012, when they were demerged from Vesuvius, together with the results of the US Precious Metals Processing business for the period up to 1 May 2012 when it was sold and the European Precious Metals Processing business, which was held for sale as at 31 December 2012, for the whole of the year. Prior year comparatives have been restated accordingly.
