Notes to the Condensed Interim Financial Statements 19. Derivative Financial Instruments The Group uses derivative financial instruments solely for management of an underlying risk. The Group minimises its exposure to market risk since gains and losses on derivatives offset the losses and gains on the assets, liabilities or transactions being hedged. It is the Group’s policy not to enter into derivative transactions for speculative purposes. 30th June 2023 31st December 2022 Assets Liabilities Assets Liabilities HK$M HK$M HK$M HK$M Interest rate and cross-currency swaps – cash flow hedges – due within one year – – – – – due after one year 142 – 96 – 20.
