Mr. Pat McArdle:

Well, let me take that. The system changed and it moved away from the two-and-a-half times to the after-tax ... the proportion of debt service cost as a fraction of after-tax income. And we all had various indices which modelled that. I had one. I'm sure AIB had one. Dan had one. DKM had one and still has one. So it ... and that captured ... that model captured a lot of things that improved affordability, such as massive reductions in income tax, extension of loans ... I've forgotten the other factors. I have them here somewhere on a slide. There are about five different things. So ... and ... so ... when ... when ... it was only when the ECB raised rates round about 2006-7 up to 4%-4.25% that that affordability became stretched.
