The Chicago Board of Trade has altered the way it deals with ethanol, slightly. In a release on Monday it said:
Ethanol futures have been trading at the CBOT, now part of the CME Group, since March 2005. The Ethanol futures prices will be used in the settlement of both the options on Ethanol futures and the cash-settled options. Forward Month Ethanol Swaps, launched in December 2006, will serve as the underlying value for those options.
