In respect of each board lot of CBBCs, the residual value is an amount in Hong Kong dollars calculated by the Issuer in accordance with the following formula:

For Bull CBBCs Residual Value Entitlement x (Minimum Trade Price - Strike Price) x one Board Lot = per Board Lot Number of CBBC(s) per Entitlement

For Bear CBBCs Residual Value Entitlement x (Strike Price - Maximum Trade Price) x one Board Lot = per Board Lot Number of CBBC(s) per Entitlement

Subject to the occurrence of a settlement disruption event, all holders will receive the residual value (net of any exercise expenses) (if any) no later than 02 August 2021, which is three CCASS settlement days following the end of the MCE valuation period.
