Mr. Chairman, they actually come into play under the Revolving Fund Act. The petroleum product revolving fund is mentioned in that act. With respect to pricing policy, the policy is dictated by the fact that we break even. When we are not able to break even or we make a profit, the stabilization fund is put in place that allows for those kinds of calculations. There is a limit on the fund of $5 million that we can't exceed, but within that we can have variations on a year-by-year basis. In fact, the variations have been deficits for the last number of years although, given the size of the overall program, they've been quite close to a break-even point.
