The exchange must have default rules which, in the event of a member of the exchange being or appearing to be unable to meet his obligations in respect of one or more market contracts, enable action to be taken in respect of unsettled market contracts to which he is a party.

The rules may authorise the taking of the same or similar action in relation to a member who appears to be likely to become unable to meet his obligations in respect of one or more market contracts.

The rules must enable action to be taken in respect of all unsettled market contracts, other than those entered into by a recognised clearing house for the purposes of or in connection with the provision of clearing services for the exchange.
