We have identified hedge accounting (including the valuation of hedging instruments) as a key audit matter because hedge accounting under HKFRS is a complex area and the Group has entered into a high volume of hedge contracts,
necessitating a sophisticated system to record and track each contact and calculate the restated valuations at each financial reporting date. The valuation of hedging instruments and consideration of hedge effectiveness can involve a significant degree of both complexity and management judgement and is subject risk of error.
