The rate guarantee is implicit in the fact that it is a Crown corporation. It's owned ultimately by His Majesty in right of Canada, as we call it officially, so the financing of government borrowings is done at a rate that is advantageous for the corporation, although it's slightly higher than the cost of borrowing for the Government of Canada.
The guarantees when the corporation got financing on the private market were probably done at a favourable rate, knowing who was ultimately behind the borrowings. From that perspective, the pipeline is benefiting from rather favourable terms of borrowing, both on the private and the public side.
What was the other part of your question?
