Thank you, Dr. Moran.
That concludes the statements by witnesses.
We'll now go to rounds of questioning by members. I will ask members to please identify who you're directing your questions to in order to make best use of your time. We have six witnesses today, and there's nothing worse than having everybody stare at the screen or at one another.
We'll start off with Mr. Arnold for six minutes or less.
I will note that Dr. Reynolds has a hard stop at one o'clock our time, so if you have questions for Dr. Reynolds, you might want to get them in before that time slot.
We have Mr. Arnold, please, for six minutes or less.
