No, in the sense that I think what the OECD and others have said is to calculate with a level of assurance that then could be used in terms of the practical administration of income tax and other taxes. There's a whole academic exercise that academic communities could carry on, and maybe for some purposes it has value, but I don't think that has shifted significantly from the OECD's perspective a year later.
