Effective dates will be subject to the UK endorsement process.

The Group is currently assessing the impact of the above standards, but they are not expected to have a material impact other than in respect of IFRS 18.

IFRS 18 replaces IAS 1 and requires that companies classify all income and expenses into five categories in the statement of profit or loss, namely the operating, investing, financing, discontinued operations and income tax categories. Management-defined performance measures are disclosed in a single note and enhanced guidance is provided on the aggregation and disaggregation of information presented in the financial statements. The Group is in the process of assessing the impact of IFRS 18 and anticipates changes to certain presentational and disclosure-related matters in its consolidated financial statements in future periods.

The Group has not adopted any other standard, amendment or interpretation that has been issued but is not yet effective.
