There can be a range of rationales, but when departments come in, they have to request more than three-twelfths and have to provide an explanation to the Treasury Board Secretariat. Then, what you see reflected in the interim supply bill is the overall number for all those organizations with three-twelfths, and then you see it broken down by each exception, so that you understand which organizations and which votes are requesting more than their three-twelfths.
You'll notice in the bill this afternoon that you have three organizations requiring eleven-twelfths in a certain vote. Typically that has to do with the need or a potential need for that expenditure to be made almost in its entirety between April and June. There are about 30 organizations that require, in one or more of their votes, more than the three-twelfths, and those are explicitly set out in the interim supply bill. And there is a story behind each.
