I have mentioned that we will always be tested. Let's not be naive. One of the issues here was that the whole ecosystem was extremely naive. I think our government and the folks who work there are really doing an excellent job of trying to mitigate the risk and to make it foolproof, but it is never perfect.
We talk to our colleagues—we have a very close relationship with NSF in the United States—and try to understand what loopholes they potentially see. It is something that has to be constantly tweaked and improved as we see what the results are.
