Thank you very much.
Mr. Northey, I do want to ask you a question. Yesterday morning, the associate deputy minister stated that extended interswitching was allowed to lapse because it wasn't heavily used, but was having unintended consequences in terms of the competitiveness of our railways vis-Ã -vis the U.S. railways. I guess there has been some confusion in some of the testimony we've been given when witnesses have said it was a remedy that wasn't used very much, but then they go on to talk about the implications and consequences it's had in the marketplace. Could you comment on that?
