Well, that is our system. I'm not overly familiar with how that is done, to the extent that we're requesters, we're not commercial. We have not run into that, and we have not had experience with that.
There are a number of policy reasons for doing it that way, especially if you have flow-throughs, reasons of GST, or other things. There are a number of reasons it could be done that way. In B.C. we have not had any particular problems with it being done the way it is. But I would really have to refer you to Mr. Loukidelis for detailed information on that.
