I would say the main difference between the 2005 rate-setting mechanism and the one that is likely with the changes that are before you today is the surpluses. The proposed board will have the management of a reserve, and then if there's a surplus the board would have to take that into account in setting the rate going forward. I think that's the main change, but I can be corrected by my colleagues if they want to add something.
