Subject to the Act, the Exchange may, from time to time and in its absolute discretion, de-list any Contract. If there are no Open Positions in the relevant Contract which the Exchange wishes to de-list, any de-listing shall become effective at such time as the Exchange shall determine. If there are Open Positions in the relevant Contract which the Exchange wishes to de-list, the Exchange may require that such Open Positions be cash settled immediately or restrict trading only to enable the Closing Out of those Open Positions, except to the extent that the Exchange deems such trading to be necessary for the maintenance of a fair, orderly and transparent market.
