Right. Maybe we'll come back to that with other witnesses.
I want to talk to you about the TIEAs, the tax information exchange agreements. You talked about 60 having been negotiated, and six are in negotiation stage. Several experts, some of whom we'll be hearing from later today, have said that these on-demand agreements really accomplish very little because you have to know what to ask for in order to get any information back.
I'd like to ask you, and perhaps Mr. Cook may have some information on this as well, how often have we used TIEAs, and how much information have we received as a consequence?
