where in their full year result coming out, page-7

Thanks for the explanation Khibbins .
I knew it was something along those lines ,just dont know the finer points ,having never tried those kind of transactions .Looks like they must have put them in place while the Tin price was quite high ,and showed very good judgement in my opinion .The fact that they didnt hedge huge amounts is also prudent as it has bought others undone in the past .Top points from me on that one .If you can pick the tops ,as management seem to have done , these zero cost collars seem to be a great way to go .
