Okay, thank you very much.
I do want to turn my attention to some other issues under the supplementary estimates (B) 2010-2011. This is under the introduction of the supplementary estimates, on page 11:
As a result of accounting changes due to the Jobs and Economic Growth Act, public debt charge forecasts from the Federal Budget are no longer a reasonable estimate of cash-basis expenditures for reporting in Estimates. This revised forecast is based on a change in methodology and better reflects the amounts to be charged to the statutory authority in 2010-11.
Can you explain the nature and rationale of the accounting changes that have been put in place? And do you believe that the accounting change with a fiscal impact of $2.9 billion can be more clearly explained than what you've just indicated? And did you speak to the Auditor General concerning the same?
