Hong Kong Futures Exchange (HKFE), a wholly-owned subsidary of Hong Kong Exchanges and Clearing Limited (HKEx), announced today (Thursday) methods to determine the Official Settlement Prices (OSPs) for stock index options contracts which expire today, 29 September 2011, and the Final Settlement Prices (FSPs) for stock index futures and stock futures contracts that have their final trading day today.

If Typhoon Signal 8 or above is cancelled at or before 12:00 noon, trading will resume in the afternoon and HKFE will use the average of the index and relevant stock price quotations taken every five minutes in today's afternoon trading session to determine the OSPs and FSPs.

If Typhoon Signal 8 signal or above remains issued at 12:00 noon, there will be no trading today and HKFE will follow the procedures for expiry days and last trading days and use the average of the index and relevant stock price quotations taken every five minutes on the next trading day to determine the OSPs and FSPs.

There was no morning trading in HKEx's markets today due to the Hong Kong Observatory's issuance of Typhoon Signal 8.
