Mr. Chair, I have a point of clarification that Ms. Burr could answer. On my question earlier on the return on capital, I talked to Mr. Hoback and Mr. Storseth. They're of the same opinion as I am. In fact, a vice-president of CN Rail, before the transport committee, indicated that they were assured of a 20% railway cost.
Ms. Burr, under the revenue cap, are the railways assured of a guaranteed return on capital? How does that work? Mr. Ruest and I are both of a different opinion on this. Are the railways assured of a return on capital under the revenue cap?
