Thank you.
I'll start with you, Mr. Greer. You mentioned that when we're dealing with long-haul interswitching, the absence of reciprocity is a problem. When we spoke with some of the witnesses who testified on behalf of the railways, one of the things that came out of the testimony was that in fact a very, very small portion of their business is subject to being lost to the United States.
What's the extent of this actual threat, with the lack of reciprocity, with business going to American railways?
