Starting in 2026, the insurance industry will adopt International Financial Reporting Standard 17 (IFRS 17), which eliminates the 'carve-out' method for financial assets. Some financial assets will be reclassified as FVOCI accounting items. Gains/losses from the disposal of FVOCI equity instruments will not be recognized in current period profit or loss but will be directly reflected in retained earnings. However, they remain distributable surplus. Adjusted profit is provided concurrently to reflect performance and the source of dividends.
