(Concluded)

The Company’s goodwill has been tested for impairment at the end of the annual reporting period and the recoverable amount is determined based on the value in use. The value in use was calculated based on the cash flow forecast from the financial budgets covering the future five-year period, and the Company used annual discount rates of 8.0% in both years in its test of impairment as of December 31, 2020 and 2021, to reflect the relevant specific risk in the cash-generating unit.

For the years ended December 31, 2019, 2020 and 2021, the Company did not recognize any impairment loss on goodwill.
