I'll get my staff to comment on some of the technical and detailed financial aspects of your question, but I want to make one point. The way the funding flows for projects is different for capital projects than it is for operational projects. The capital projects take multiple years to finish, so money might be allocated in one year but may not be spent that year. It may be transferred over to the next year, and then it gets re-profiled in the next year.
That way, some of the numbers don't match in that sense, even though the overall project cost is the same and the amount of money being spent is the same. How much money gets spent in year one, year two, year three, or year four differs from year to year, depending on when the bills come in from other partners.
I'll ask the staff members to comment on some of the detailed numbers in the estimates.
