You have to start by saying there was good intent. The good intent was that instead of indexing the GIS annually, we'll give you indexation every three months to really make sure that you're okay. It starts with good intent, and then you have those oddities that are there. The perfect scheme would probably be to have everything indexed the same, but then it's very difficult on the CPP front, as I understand.
