It's a Canadian regulation. It's under the Canada Transportation Act. What it does is create a 160-kilometre zone in only three provinces—Alberta, Saskatchewan and Manitoba—where there's a cost-based rate applied to traffic interchanged to a competing carrier.
What that means for us on our network is that, because we interchange with the BNSF at Coutts, Alberta, right at the border.... What this Canadian regulation does is give the BNSF a 160-kilometre reach into Canada to solicit traffic exposed within that zone at a cost-based rate. Essentially, they can undercut us marginally on the long-haul portion of the movement. They can get that traffic. There's an incentive being created with that cost-based rate to move traffic under a competing American rail carrier.
