Issuer notices set 19 October for the Shanghai delistings of Dongxing Securities and Cinda Securities under CICC’s share-swap absorption. Conversion and replacement-share listing are separate steps, with practical consequences for how brokers display and value positions.[1][2]
Exchange terms for the 16 October record date
| Legacy share | CICC A shares per share |
|---|---|
| Dongxing Securities | 0.4376 |
| Cinda Securities | 0.5210 |
The notices warn that legacy holdings and their value disappear from accounts after delisting until replacement shares list. CICC is to announce conversion results and the new listing separately; those stages remain distinct.[1][2]
HKEX’s participant circular sets 20 October for Cinda’s removal from the China Connect securities list because 19 October is not a Northbound trading day. Brokers maintaining eligibility lists need to distinguish the mainland delisting timetable from Hong Kong’s access calendar.[3]
Shengang Securities describes a specific approach for its margin accounts. From 16 October clearing until the new shares list, it displays estimated CICC holdings and their value based on the exchange ratios, and uses that value to calculate the maintenance collateral ratio. Those provisional shares cannot trade before listing; final quantities follow ChinaClear Shanghai’s registration.[4]
This creates a practical reconciliation task. A broker may maintain an indicative value for collateral while the exchange conversion remains unfinished. Customer reporting needs to make clear which quantities are provisional and which securities can actually be sold. A displayed position is useful accounting information, but trade availability depends on completion of the listing process.
