In addition, an options contract on the spread between December 2005 and March 2006 will be added on March 1, when the March 2006 underlying futures contract is initially listed.
The 12 consecutive one-month spreads and the options on spreads between the first and third nearby months, the first and fourth nearby months, and the second and fourth nearby months will continue to be listed.
Exchange President James E. Newsome said, "The Exchange expanded the listed months for gasoline calendar spread options contracts to provide market participants with more versatile risk management and arbitrage opportunities."
