Unquoted shares and limited partnership classified as available-for-sale are designated as at FVTOCI and the changes in fair value accumulated in other equity are transferred directly to retained earnings instead of being reclassified to profit or loss on disposal. Impairment losses previously recognized and accumulated in retained earnings are adjusted by the Group to record an increase in retained earnings and a decrease in other equity, unrealized gains or losses on financial assets at fair value through other comprehensive income, since no subsequent impairment assessment is required under IFRS 9;

Quoted shares classified as available-for-sale are classified as at fair value through profit or loss under IFRS 9. Open-end mutual funds classified as available-for-sale are classified as at fair value through profit or loss under IFRS 9 because the contractual cash flows are not solely payments of principal and interest on the principal outstanding and they are not equity instruments. The Group reclassifies unrealized gains or losses on available-for-sale financial assets in other equity to retained earnings;

Time deposits with original maturity of over three months, pledged time deposits and guarantee deposits are classified as measured at amortized cost under IFRS 9 because, on initial recognition, the contractual cash flows that are solely payments of principal and interest on the principal outstanding and these investments are held within a business model whose objective is to collect the contractual cash flows; and

Debt investments with no active market are classified as at fair value through other comprehensive income under IFRS 9, because, on initial recognition, the contractual cash flows that are solely payments of principal and interest on the principal outstanding and these investments are held within a business model whose objective is achieved both by collecting contractual cash flows and selling financial assets. The Group adjusts those debt investments and other equity, unrealized gains or losses on financial assets at fair value through other comprehensive income, based on their fair value.
