I thank you very much for your insightful presentation. It has been an amazing morning in terms of the presentations we've had here.
The bells haven't been rung yet, so I'm going to go straight ahead. I apologize in advance for when they ring, if they ring.
Dr. Plummer, I understand you have to leave at 12:15 p.m. I wanted to make the committee aware that Dr. Plummer has to leave at 12:15, so any questions for him should be asked before then.
Dr. Marra and Dr. Huntsman, I understand you are with us until 12 noon. Are you able to stay a few more minutes for some questions?
