I noticed a vast difference between the top 20 in the 2012 Fin. Report and the Scheme Booklet and am posting this in case someone else spots it - and save you time. Peter Armstrong of SLR tells me the difference arises not from a change in shareholding per se, in 4 months, but because they rearranged the list. Not the best of ideas I told him, but if it helps, that is their explanation.
