I want to pick up on a question that my colleague asked about the PBO's report on the supplementary estimates.
There seems to be some discrepancy at times between Treasury Board's analysis of their numbers in supplementary estimates (C) and the main estimates and the PBO's analysis of the numbers.
As we look at them and try to read the estimates, could you or your officials explain whether there is a difference between the systems the PBO uses and the systems you use?
