Do you have any examples in mind of where there's been a prestudy or a study done on the analysis of even the interaction? In this case, I think what Ms. Kwan is pointing to is what we've heard from some stakeholders, that there are interactions between some of the non-refundable tax credits and the income tax cut.
I'm just wondering whether there's an analysis done internally on a fairly regular basis when there's such interplay or when there will be an impact on people. How do you assess that?
