The Group distinguishes its segments between mining operations, refining services (which include metals purchased and toll refined) and other. Management has determined the operating segments based on the business activities and management structure within the Group. Operating segments have consistently applied the consolidated basis of accounting and there are no differences in measurement applied. Capital expenditure comprises additions to property, plant and equipment (note 5), including additions resulting from acquisitions through business combinations. Sales to the two largest customers in the Impala mining segment comprised 9.6% and 11.0% (December 2010: 10.8% and 10.9%) (June 2011: 10% each) of total sales.
