Option Style
Options are European style and will be automatically exercised on the expiry day if they are “in the money”. The future resulting from exercise immediately goes to cash settlement relieving market participants of the need to concern themselves with liquidation or exercise issues. If an option is “out of the money” it will expire automatically. It is not permitted to exercise the option on any other day or in any other circumstances. No manual exercise is permitted.
Option Premium / Daily Margin
Calendar Spread Options are equity-style and there is no daily Variation Margin payment. The premium on the Calendar Spread Option is paid/received on the business day following the day of trade. Net Liquidating Value (NLV) will be re-calculated each business day based on the relevant daily settlement prices. For buyers of options the NLV credit will be used to off-set their Original Margin (OM) requirement; for sellers of options, the NLV debit must be covered by cash or collateral in the same manner as OM requirement. OM for all options contracts is based on the ICE® Risk Model
