FORWARD TOGETHER 94 Notes to Condensed Consolidated Financial Information 30 June 2023 30. FAIR VALUE HIERARCHY OF FINANCIAL INSTRUMENTS (continued) The Group entered into derivative financial instruments, including foreign currency forward contracts, put option contract and cross-currency interest rate swap. The fair values of foreign currency forward contracts are measured using quoted prices of similar financial assets adjusted for the transaction expenses. The fair values of cross-currency interest rate swaps are based on financial institution's net present value calculation. The fair value of put option contract is determined using option pricing model based on the present value techniques that reflect both the time value and the intrinsic value of an option. The inputs used in the present value techniques included the estimated share price and discount rate, which involve a significant degree of management judgement where adjustments may be made by management for differences between the share price of investment in associate and the referenced comparable.
