Changes in Timing and Location of WTI-Brent Spread Trading
With the launch of the Dublin trading floor on November 1, 2004, the Exchange allowed the trading of a WTI-Brent spread, which is quoted at a differential and is split into the respective legs of the spread when the spread is cleared. The Exchange has determined to amend the hours and location of trading to permit WTI-Brent Spread trading on the Dublin trading floor, during the hours that the Dublin trading floor is open (i.e., from 10AM to 7:30 PM Prevailing Dublin time). Trading will only take place on the Dublin floor and, thereafter, on NYMEX ACCESS®. The trading hours for this WTI-Brent spread are to be amended as follows:

Effective Trading Hours for WTI-Brent Spread Trading
