Mr. Patrick Davitt:

It is roughly every four years the blue book is issued. Now, it could be in between that as well. There is a new one coming out in 2016. It is being part-written at the moment. So the next one will be, the eighth edition will be in 2016, the last one was in 2012. The one before that was in 2008. So it could have been in the beginning, because the blue book was a new document that was written with valuation standards, so it changed possibly quite often. So until such a time as they got a firm view on the valuations standards or the valuation standards they were putting into it, until they got them right from their point of view.
