On Monday, December 3, 2007, the Central Bank of Brazil (Banco Central Do Brasil) informed CME Group that the end-of-month spot “PTAX Rate” that it will publish on Monday, December 31, 2007, will be the same rate as determined and published on Friday, December 28, 2007.  CME Group uses the reciprocal of the end-of-month “ PTAX Rate” to cash settle expiring CME Group Brazilian real futures and options contracts.  As a result, the Board of Directors approved a change in the January 2008 Brazilian Real Futures and Options termination date from Monday, December 31, 2007 to Friday, December 28, 2007 .

This action follows that of the prior seven years.  The exchange changed the January 2008 CME Group Brazilian Real futures and options contracts termination date to enable the futures last trading date to coincide with the date of determination of the spot market rate used for final settlement.
