Thank you, Mr. Chair.
Gentlemen, allow me to add my voice to those of my colleagues in welcoming you here this morning. It's very nice of you to take time to share information with us.
I have one question that is an open-ended question, and I would invite any and all of the panel to respond to it. The question is really what have you seen as the biggest challenge in your planning to stage the games, and how have you dealt with it?
