of qualifying corporations is taxed at8.25% and the remaining assessable profits at16.5%. The Ordinance is effective from the year of
assessment 2018-2019. According to the policy, if no election has been made, the whole of the taxpaying entity’s assessable profits
will be chargeable to Profits Tax at the rate of16.5% or15%, as applicable. Because the preferential tax treatment is not elected by

Kong did not have assessable profits that were derived Hong Kong during the years ended December 31, 2024, 2023 and 2022. Therefore, no
Hong Kong profit tax has been provided for in the periods presented. Our returns for 2018 and subsequent tax years remain subject to examination
