It would be interesting to know how many WMK holders retained there investment in the unlisted version. It was an 'opt out' situation, so maybe inertia kept a few in.
I think I've posted this before, but I wasn't that happy with the WMK de-listing. They subtracted an extra 3c of taxes from the post tax NAV, then didn't return my call when I rang to ask why. Needless to say I didn't hang around.
