Perhaps I can start by answering that question. I think Dr. Steedman would be able to agree with me that I think some elements of Keystone have begun. There has been some construction that has begun.
In addition, to your specific question, Ms. Perkins, the bill has a number of financial measures that are in place, so should the project be built before it's in operation, it will need to comply with all the different financial requirements that are in this bill.
