Thank you. I share the thoughts of my colleagues about your taking your time to be here today. We really appreciate your being here to field our questions.
I have a couple of questions. I'll start with NEXUS. It seems to me that it is a technology that has some potential for good and for future growth. Is it the only technology—or are you looking at it in that way—for a much broader application, or are there other technologies you're looking at in parallel to it that could enhance the security at our borders?
