Final answer:
True, IFRS requires that financial liabilities, except those held for trading, be measured at amortized cost using the effective interest method, as outlined by IFRS 9.
Step-by-step explanation:
The statement that IFRS requires that financial liabilities other than those held for trading must be measured at amortized cost is True. According to the IFRS, financial liabilities are first measured at fair value and subsequently measured at amortized cost using the effective interest method, except for financial liabilities at fair value through profit or loss. These include financial liabilities held for trading or financial liabilities designated at fair value through profit or loss under IFRS 9.
