3. Accounting estimates

The preparation of these financial statements requires management to make certain assumptions, estimates and judgements that affect the reported amounts of assets, liabilities and disclosure of contingent assets and liabilities as of the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results may differ from those 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 revision and the future periods if the revision affects both current and future periods.

The table below presents the areas that involve a higher degree of judgement or areas where assumptions and estimates are significant to the financial statements:

Detailed explanations of the degree of judgement and assumptions used are included under each of the respective sections in the notes to the financial statements as referenced above.
