We hold the neutral portfolio. The question that you rightly raise is, should we shift that to say, given the public interest in climate change we should shift the make up of the portfolios being one that is on the way to natural however you want to define it? I think there is a very strong argument for doing that. Actually the way this is governed we would have to agree that with the Treasury because the nature of the risk in that portfolio is something that ultimately goes off to the states. I would intend to have that discussion with the Treasury because I think it's a perfectly sensible thing to do. By the way, I don't think Mark would in any way disagree with this. I know it's beyond the list of things to do. I don't think it's a perfectly sensible thing and I will take it forward. Will that be a priority? It makes sense. It will be a priority. Thank you. I think there's a lot of other things. I think we'll return to this subject in more detail in future sessions, I'm sure.
