Business units have been classified according to the Group’s management structure. Generally, business units are allocated to product groups based on their primary product. The Aluminium group excludes Pacific Aluminium, Other Aluminium and the Cable division of Alcan Engineered Products which are included in “Other operations”.

1. (a) Gross sales revenue includes 100 per cent of subsidiaries’ sales revenue and the Group’s share of the sales revenue of equity accounted units (after adjusting for sales to subsidiaries).
2. (b) EBITDA of subsidiaries and the Group’s share of EBITDA relating to equity accounted units represents profit before: tax, net finance items, depreciation and amortisation. Underlying EBITDA excludes the same items that are excluded from Underlying earnings.
3. (c) Net earnings represent profit after tax for the period attributable to the owners of the Rio Tinto Group. Earnings of subsidiaries and equity accounted units are stated before finance items but after the amortisation of discount related to provisions. Earnings attributed to business units do not include amounts that are excluded in arriving at Underlying earnings.
4. (d) Underlying earnings is the key financial performance indicator which management uses internally to assess performance. Underlying earnings is defined and reconciled to net earnings in note 2 of the 2011 financial statements.
5. (e) Capital expenditure comprises the net cash outflow on purchases less disposals of property, plant and equipment, capitalised evaluation costs and purchases less disposals of other intangible assets. The details provided include 100 per cent of subsidiaries’ capital expenditure and Rio Tinto’s share of the capital expenditure of equity accounted units. Amounts relating to equity accounted units not specifically funded by Rio Tinto are deducted before arriving at total capital expenditure for the Group.
6. (f) Operating assets of subsidiaries comprise net assets excluding post retirement assets and liabilities, net of tax, and are before deducting net debt. Operating assets are less non-controlling interests, which are calculated by reference to the net assets of the relevant companies (ie net of such companies’ debt).
