Migration of Open Interest from Mont Belvieu Ethane Swap (W8) to Mont Belvieu Ethane 5 Decimals Swap (C0)

Please be advised that effective close of business on Monday, November 30, 2009, the New York Mercantile Exchange, Inc. (the “Exchange”) will migrate open interest from the 4-decimal priced Mont Belvieu Ethane (OPIS) Swap Futures (Code W8, Rule 586) to the 5-decimal priced Mont Belvieu Ethane 5 Decimals (OPIS) Swap Futures (Code C0, Rule 410) contract in response to customer demand.  The W8 product has been replaced by the Mont Belvieu Ethane 5 Decimals (OPIS) Swap Futures (Code C0), which uses 5 decimal trade and settlement prices.  

The migration of open interest will have the effect of liquidating all open positions in the Mont Belvieu Ethane (OPIS) Swap Futures (Code W8) contract and establishing equivalent new positions in the Mont Belvieu Ethane 5 Decimals (OPIS) Swap Futures (Code C0) contract. 

As a result of this migration, the Exchange will delist the Mont Belvieu Ethane (OPIS) Swap Futures (Code W8), and its related overlying average price option contract, Mont Belvieu Ethane (OPIS) Average Price Option (Code F1, Rule 586A) and related overlying BALMO, Mont Belvieu Ethane (OPIS) BALMO Swap Futures (Code V4, Rule 315). The delisting will also become effective at close of business on Monday, November 30, 2009.
