Definitions The following are referred to throughout this presentation:- NSV is revenue less commodity metals (tin, silver, gold). Adjusted operating profit, adjusted profit before tax, adjusted profit for the year and adjusted earnings per share are, where appropriate, each stated before: exceptional items; amortisation of acquired intangible assets; deferred tax on acquired intangible assets and goodwill; utilisation of deferred tax assets (where initial recognition was as an exceptional item); acquisition costs; the impact arising from the fair valuing of financial instruments; and profits or losses arising on business disposals. Adjusted cash generated from operations is cash generated from operations after adding back 0.2m (2013: 4.8m) for demerger cash costs. Free cash flow is defined as net cash from operating activities after net outlays for the purchase and sale of property, plant and equipment and dividends from joint ventures but before additional funding contributions to Group pension plans. 40 40
