The new pipe options contracts and their commodity codes are: PGE Citygate (CW); Alberta (PI); Northern Rockies (ZR); Transco Zone 6 (TZ); Chicago Citygate (PY); Houston Ship Channel (PK); San Juan (PJ); SoCal (ZN); and Panhandle (PU).

The contracts will be 2,500 MMBtu in size, with a minimum price fluctuation of $0.001 per MMBtu. The contracts will be listed for 72 consecutive monthly expirations, with the first listed expiration month of January 2008. The contracts expire on the termination day of the underlying basis swap futures contracts.

There will be five strike prices in intervals of $0.01 per MMBtu above and below the at-the-money strike price and will be adjusted according to the futures price movements.
