In terms of, again, looking at it, the pros and cons, we did look at everything. From more of an industry perspective, we tried taking a look at existing ones. For example, Health Canada has one that was built in. They put it in as a 2% escalator. We looked at the benefits of those. From my perspective, if I were running one of the programs, having an escalator built into my actual legislation, where I set it by something other than CPI, is the ideal. Whether we take a different basket of CPI or a different...we looked at all those things. In some cases, the pros and cons of all of those are that it fits better with certain segments of the service fees environment. In others, it didn't fit as well. I take the point in terms of it being an overly simplistic model by taking CPI; however, we actually did that intentionally again. We figured that this covered a broad basket of goods. It was something that people understood, including the potential users, whereas if we came up with some other type of mechanism or whatever...explaining that.
Quite simply, as well, in terms of the articulation of it in legislation, because we actually put it into the legislation, CPI is one thing that can be clearly understood. It's articulated specifically in terms of the wording, in terms of how StatsCan calls that inflation indicator, and whatnot.
Again, I guess there are other options, but my feeling, in conclusion on that, would that many of those other options fit specifically within a niche set of fees versus something that could apply across the full gamut of the thousands of different types of fees that exist.
