Mr. Pat McArdle:

Sorry, Chairman. Can I finish my point though? I just want to quickly, very briefly say the 2007 ... that's why we applied the model. We had tremendous difficulty in doing it ... we ended up with maybe 100 variables, not five or six. We got a result and I gave you the result today in my thing ... and I just want to draw your attention to it ... to show you the type of result we got. And we got a 36% fall in house prices, which was pretty good actually.
