I'll just briefly walk through the formula, which is, as I said, a touch complicated.
C is the amount estimated to be collected from the fuel charge. D is the amount estimated to be paid to individuals, and potentially others, under the Income Tax Act. You're basically making sure that any payments are taken into account before the maximum is set. When you get to B—and there are four components of B—that's looking at previous periods that have occurred to make sure there's a true-up in that period for previous periods.
That's why you're looking at, again, the amounts that have been collected from the fuel charge in E—the amounts that have been paid out to individuals and potentially others in relation to the rebates. Then, looking at the actual payments that have been made, which is G, pursuant to this authority, and then finally there is a true-up in relation to a lag effect related to entities' relationship with the Canada Revenue Agency. That is the purpose of H.
