Thank you, Mr. Chair.
I was almost tempted to call a point of order. I didn't at that time, but I do want to note that it is the supplementary (B) estimates that we're here to talk about. I noticed that the questions at the start were drifting away from supplementary estimates (B), so I just want to make this comment. I think it's important that we focus on the very important job we have here today in terms of the supplementary estimates.
Having said that, I notice you talked about $4.497 billion that is your main estimates, plus the supplementary estimates. You actually bring in approximately $360 billion in revenue, so I think that perhaps unlike any other department, you have a very different role compared to the majority of departments within government.
Has that remained relatively stable over time, in terms of expenditures versus revenues? Can you speak briefly to that?
