Okay. That's very helpful.
Everything you've done has been very helpful, and as I mentioned at the beginning, you've also been very patient with our technical problems. I want to thank you, Professor.
I guess what will happen, as we have a little bit of follow-up to do, is that our clerk will be in contact with you about the materials we have enquired about.
Again, on behalf of the entire subcommittee, thank you very much for attending today.
