The issuer’s existing CBBCs are still valid and you can continue to trade them through the Exchange trading system. The issuer must publish an announcement regarding the credit rating downgrade and continue to provide liquidity for its existing CBBCs and perform its settlement obligations upon expiry.
However, when an issuer no longer meets the eligibility requirements in the Listing Rules, the issuer will not be allowed to launch new issues or further issues. It must apply for the withdrawal of CBBCs launched but not yet listed and all CBBCs with no outstanding positions held by the public.
You should be cautious that prices of CBBCs issued by the affected issuer may be affected by its or its guarantor’s credit downgrade. For the avoidance of doubt, where the issuer or the guarantor relies on the credit rating of their respective holding company for satisfying the eligibility requirements under the Listing Rules, such credit rating is for investors’ reference only, and investors shall have no recourse against the relevant holding company under the terms of the CBBCs.
You can access information about the credit ratings of the issuers, their guarantors (if any) or their respective holding companies (where such credit rating is relied upon for satisfying the eligibility requirements in the Listing Rules) on the HKEX’s website.
