Mr. Chair, the incremental costs for the mission in Afghanistan to date is $2.1 billion. It is estimated, going forward to the end of the mission, that there will be a further $1.8 billion expended. So, total incremental costs estimated to the end of the mission, that is February 2009, and also getting the forces home if that is the decision at the time, will cost $3.9 billion incrementally.
