I understand that 30% is a big number. What we're very carefully saying is that actually our estimate is a fuzzy one and that it's centred on around 20%, which is still an important number. I agree with you. However, we think this is one of the byproducts of what we've been through. It's not something that happened by itself. It's happened as a product of the experience in the post-crisis period, and as the fundamentals catch up to it in our forecast it will be sustained.
