Mr. Chair, I'll take a stab at that, and then if I'm not successful I'll turn to Bill Matthews.
A number of the votes that we request in terms of main estimates are central votes. They're attributed to the Treasury Board Secretariat, but they are actually expended by other organizations. So for example when we look at the operating budget carry-forward at $1.2 billion, while it is attributed to the Treasury Board Secretariat, it is actually expended and disbursed in the course of the year to a raft of departments and agencies. So the actual expenditures related to that are reflected in their own expenditures. That's why there is a difference in terms of the spending authority that we request and the actual expenditures, which are made by organizations once we distribute the funds.
The same thing happens with, for example, the paylist, which is vote 30. We request funding and the spending authority on behalf of the government as a whole, but then we redistribute those depending on the need and use by departments. So it is reflected in each one of those organizations.
Is there anything you'd like to add?
