A system and method are provided for settlement and delivery of cash settled futures contracts overlying open-ended mutual fund shares with optional delivery of mutual fund shares when physical settlement is elected. On the last date of the contract, a party which has an open position in the contract tenders the clearing organization a request to elect optional physical settlement of a specified number of shares of the mutual fund in additional to the standard cash settlement of those contracts. The clearing organization, upon acceptance and when it is certain of the requestor's final position in the futures contract, it processes the election request against the requestor's final position and possibly submits an order on behalf of the requestor to the investment company which manages the mutual fund to purchase or redeem shares of the open-ended mutual fund in a quantity roughly the size of the requestor's final contract position.
