Okay, so nobody knows how much money they make—or no one is willing to disclose how much money they make from their credit card services, which is more true, I would say. It is highly profitable, is it not? I'm going to assume that the answer is yes.
What is the justification for the interchange fees? I well know that the credit card companies have stated that the banks are essentially responsible for setting the fees. You guys say that you're not responsible, that they're responsible for setting the fees. It may be both of you. I note also that the banks all own their own payment processors. I have that in my briefing note here.
What percentage of the interchange fees do your banks get to set? Can you please explain that?
Mr. Siromani, I'm going to you first.
