Sure. Thank you for the question.
This number was obtained by comparing the permanent frozen allotments in supplementary estimates (C) against the total permanent frozen allotments that you would find in the public accounts. What we wanted to highlight was that, theoretically, what you find in the supplementary estimates is technically a leading indicator of what you would find in the public accounts, and potentially what is about to lapse. Based on the figures that we've seen in the last few years, these don't really give you an indication of the permanent frozen allotment numbers that you would find in the public accounts. That's where that 26% average comes from.
