Sure. Last year, 2010-11, the main estimates came in at $261.6. billion. There was a supplementary estimates (A) for $1.9 billion, and a supplementary estimates (B) for $3.1 billion, for a total of $266.6 billion.
For those of you who may recollect last year, there was a supplementary estimate (C) tabled, but it was never actually turned into an appropriation act, so we have not included it in the totals.
