Well done THE BUG. I am in a similar position to you having bought UU.A heavily during the RI and having benefited from the leveraged uplift in their price before converting them into ORDs - I suppose my net cost was of the order of 265+165 (430 ish) minus, of course a very nice income stream along the way. I have also traded in and out a few times along the way and have currently got a limit order to sell all of the various UU holdings I manage.
At the moment it is underperforming if you hold for the medium to long term - but I would be very sorry to lose it from the UK lists as I would like to continue trading it for the next few years.
