Welcome back, everyone, with apologies to all. We're still unable to reach Dr. Roberts, but in the meantime we're going to have to proceed, because Mr. Donnelly hasn't asked his questions yet.
I apologize, Mr. Donnelly, if some of your questioning was towards Dr. Roberts. As you can see by the buffering symbol on the screen, we're trying to get hold of him now. If he's able to join us during your seven minutes, I'm willing to extend some of your time to compensate.
