A great deal of thanks to all our witnesses this morning. With this panel, we don't have enough time to get through what we would probably like to get through just by the quality and expertise of the six of you who are here.
Very quickly, Mr. Leuprecht, I want to get this balance. We've been trying to understand, particularly with regard to ISIS, ISIL, how much of their money is coming from donations from people in North America or Europe versus how much of their money they have secured from extortion from the banks they have seized, from the sale of oil as Mr. Tupman has alluded to.
Do you have any awareness of that?
