Thank you.
To Mr. Ralston again, I'm just looking at interest-bearing debt. It stood at 49.4% of GDP in 2010-11. That's down over 26 percentage points from a high of 76.1% in 1995-96. Again, this sounds like a good-news story. I'm wondering if you can explain the reasons for the lower interest-bearing debt and the implications of having lower interest-bearing debt.
That said, what are the risks we would look at if there were an increase in interest-bearing debt? Are there any risk-mitigating factors in place for that?
