Yes, we did consider extending. Some of the provisions that were in the act have in fact been carried forward, such as level of service, arbitration, and penalties when they don't meet their obligations.
We have let one sunset provision go, which was the government's prescribing the volumes of grain that had to be carried. That provision, when it was implemented, was In fact for the situation of 2013-14, the bumper crop in the bad weather. We ended up using it for only about a year and a half, and then we stopped because the railways were in fact carrying more grain than we were mandating; that situation is gone. We believe we don't need it. It wasn't used for the last two years, so there's no need for it to continue.
The other one we allowed to lapse was extended interswitching, because after the assessment we did, we uncovered that it wasn't heavily used, but it was having unintended consequences on the competitiveness of our railways vis-à-vis the U.S. railways. We replaced it with a measure that we believe will provide greater benefit to more shippers across the country, which is the long-haul interswitching provision.
