Mr. Stockton, it's nice of you to be up in our country today sharing some of your views.
I think this is a really interesting line of questioning. I have a couple questions.
You talked about the threat to the electrical system, and you've touched on both infrastructure and the cyber-threat, but I'm a little unclear. Is it a cyber-threat that you see as being the bigger concern or is it a natural physical attack on the infrastructure? Put aside a natural disaster; I'm just curious to kind of get the threat level, and where it's coming from.
