As you can imagine, when you have a problem like that you don't talk about it until you get it fixed. We don't want to give our enemies anymore information than they need.

And then, of course, the world will open for business on Monday, and that's when we'll test software systems and information processing systems.

That will actually look fairly interesting on a T-shirt.

If they didn't fix the systems, they would not be functioning. Somebody said we did it too well, we made it look too easy. Maybe that's right. Maybe we should have had a control group over here failing.

It is far too early to declare victory. We have a lot of systems and a lot of countries to go through yet before we'll see what the actual impact has been of the transition.

We'll need to monitor all weekend.
