Yes. The one we have relied most closely on is the U.K. model, but it is not a perfect mirroring, because the U.K. model is, I would say, weighted a little differently from ours. We therefore brought a particularly Canadian approach to the model we have here. Certainly as we go forward, as I said, there will be an evaluation of how it's working from a process point of view. We will evaluate if the model is correct and if the weights and counterweights are correct; it's quite possible that in the course of that evaluation we'll conclude yes or no, but we want to leave scope for that kind of conversation to happen.
If you'll indulge me, Mr. Chair, I'm going to ask my colleague here, Rose O'Reilly, if she'd like to add anything on the differences between the Canadian and the U.K. model.
