1. Basis of preparation and consolidation
 

The consolidated financial statements (financial statements) have been prepared in accordance with IFRS, the interpretations adopted by the International Accounting Standards Board (IASB), the SAICA Financial Reporting Guides as issued by the Accounting Practices Committee and the Financial Reporting Pronouncements as issued by the Financial Reporting Standards Council, the JSE Limited Listings Requirements and in terms of the requirements of the Companies Act of South Africa.

The consolidated financial statements are prepared on the historical cost basis, other than certain financial instruments, which are carried at their fair value.

The preparation of consolidated financial statements in conformity with IFRS requires the board of directors to make judgements, estimates and assumptions that affect the application of policies and reported amounts of assets and liabilities, income and expenses. Although estimates and associated assumptions are based on historical experience and various other factors that are believed to be reasonable under the circumstances (the results of which form the basis of making the judgements about carrying values of assets and liabilities that are not readily apparent from other sources), the actual outcome may differ from these estimates.

The estimates and underlying assumptions are reviewed on an ongoing basis. Revisions to accounting estimates are recognised in the period in which the estimate is revised, if the revision affects only that period, or in the period of the revision and future periods if the revision affects both current and future periods.

The financial statements are presented in South African Rands, which is also the Group's presentation currency. Assets and liabilities of foreign operations, including fair value adjustments arising on consolidation, are translated into South African rand at rates of exchange ruling at the statement of financial position date. Income, expenditure and cash flow items are translated into South African rand at rates approximating the foreign exchange rates ruling at the dates of the transactions. Foreign exchange differences arising on translation are recognised directly in equity as a foreign currency translation reserve. When a foreign operation is disposed of, in part or in full, and control is lost the relevant amount in the foreign currency translation reserve is transferred to the income statement. All financial information has been rounded to the nearest thousand unless stated otherwise.

The Group Audit committee is satisfied that the critical accounting policies are appropriate to the Group and, except as detailed below, the accounting policies have been applied consistently to all periods presented in these financial statements.
