As mentioned in the Guide for Beginners: What is a CBBC?, CBBCs have a call feature. Once the underlying asset price reaches the call price of a CBBC, trading in the CBBC will cease. The CBBC will be called back immediately and settled. Methods of settlement will be explained below.
Similar to the concept for a warrant, exercise price is the price at which purchases (in the case of bulls) or sales (in the case of bears) of underlying assets are made when the product expires. And as CBBCs are settled in cash, the exercise price can also be regarded as an indicator in calculating the product’s value, including the cash value upon expiry and the residual value after being called back.
