CY2017	caas	Description Of Withholding Tax Rate On Dividend DescriptionOfWithholdingTaxRateOnDividend	According to the Mainland China and Hong Kong Taxation Arrangement, dividends paid by a foreign-invested enterprise in China to its direct holding company in Hong Kong would be subject to withholding tax at a rate of 10% if Genesis could not obtain the Hong Kong tax resident certificate from the Hong Kong Inland Revenue Department. If Genesis obtains the Hong Kong tax resident certificate, owns directly at least 25% of the shares of the foreign invested enterprise and is qualified as the beneficial owner, it could benefit from a lower rate of 5%.
