Impairment test of goodwill The recoverable amount of CGU in Taikoo Li Chengdu in the Chinese Mainland is determined by using the calculation of the fair value less cost of disposal. It mainly represents the fair value of investment properties of Taikoo Li Chengdu by reference to the valuation performed by independent valuers at each reporting date, less cost of disposals estimated by management based on the Group’s experience with disposal of assets and on industry benchmarks. The results of the impairment test using these inputs show that the recoverable amount exceeds the carrying amount of the CGU. The Group therefore concluded that no impairment was required to such goodwill at 31st December 2023. The main valuation inputs used were effective market rents per month ranging from approximately HK$10 to HK$200 per square feet and capitalisation rates ranging from 5.75% to 6.50% determined by an independent valuer at 31st December 2023 and the cost of disposal estimated by the Group’s management. Reasonably possible changes in the key assumptions would not result in an impairment. 171
