I think the point has been made er and let me er ask you to correct me if I if you don't i it's a fair assessment, the point that's really being made is there is a judgmental issue here as to whether a surplus arises from over-funding by an employer er substantial investment performance or or effectively unfair claiming between either the deferred pensioners or the pensioners and i it can be that all of those interests have to put into the pot and it's a judgment as to who actually is doing best in what circumstances.
