2 Account Type Sink Function A system default account to keep trades and positions not emptied from Daily Account at the end of a business day. Clearing Participants will be required to move trades/positions out of the Sink Account to other accounts on the next day. Position Keeping Method Trades and positions will be attributed to house account and will be kept gross. Margining Style Gross APT A system default account used for calculating average price trades. It will store the contract value difference as a result of the rounding difference in the calculation of the APT. Intermediate trades with zero position N/A Notes: 1) Account types "CNET" and ANET are reserved for Clearing House internal use only. Clearing Participants should ignore any accounts assigned with this account type 2) During the day, an account with Net position keeping method may still have both long and short positions. The Auto-Netting process carried out during the After Business process will automatically net off the positions Separate sets of clearing account types will be created for SEOCH and HKCC Participants. For General Clearing Participants ( GCP ), a separate set of clearing account types (excluding the Daily Account, Sink Account and APT Account) will be created for keeping the trades and positions of each Non-Clearing Participant registered under its appointed GCP. For account structure of Non-Clearing Participant, please refer to section

5 Notes: 1) Trades for HKFE products executed at HKATS will store in the corresponding DCASS account and the position will be shown in the C1 account. E.g. If traders of ABC specified C as the account to store the trades, the trades will be propagated to HK CABC C. The position will be shown in HK CABC C1 Trades for stock options executed at HKATS will store in the corresponding DCASS account and the position will be shown in the A1 account. E.g. If traders of ABC specified A as the account to store the trades, the trades will be propagated to HK CABC A. The position will be shown in HK CABC A1 2) If no account information or an invalid account is specified in the order (e.g. trader of ABC enters CC instead of C1 as the account to store the trade), the system will automatically store the matched trade into a default account preset in HKATS. If the default account is HK ABC C, the trade will be propagated to HK CABC C, Errol log will be shown under the Attention field in the Trade History window for that particular trade 3) Trades that executed at HKATS and then propagated to DCASS can be identified in the Trade History Window by having Global deal nbr with value and Org. trade nbr being blank 2.5
