Mr. Joe Cullen:

The figures do not jump wildly around the place from year to year generally speaking. If we are dealing with estimates from year to year, we would have a sense of what the figures would be but there are question marks and health warnings attached to some figures because they are three or four years out of date or because events may change in the meantime. We would have a sense of it but not a very reliable figure in all cases. The question is what use that information would be put to down the road and any Minister would be reluctant to put out a figure that he or she might subsequently have difficulty in trying to defend because it was a bit flaky in the first place. Those are the practical issues that might apply.
