I think that's a good question, but I think one of the issues is the provision is in legislative authority to make a regulation. The scope and the extent of the regulation obviously would affect the scale of the work required. The frequency, as we would expect, is quite low. We don't expect that this type of issue would come in front of the CTA very often. We did have a conversation with them, obviously, before this was drafted, but I think it is early to say what the implication will be over time. But we do, on a regular basis, assess economic issues.
