Mr. Easter, the revenue cap, as you know, is a revenue-based system; it's not a cost-based system. The revenues, as you know, were developed out of the 1992 costing review. Then they were ratcheted back by 18%, and that became enthroned in the legislation as the basis for the revenue cap.
To that each year is added an inflation factor, which covers fuel, capital material. That goes into the formula to produce a revenue cap. So does the revenue cap guarantee a level of profitability? Yes. Is it set by the government? No, because it varies with the length of haul and with the tonnage that is moved. It's worked off the formula that's in the legislation.
