First thing to ask broker is, are you in the NOMINEE account or are you a SPONSORED CREST MEMBER.
There are advantages and disadvantages to both. With the former, you get no communication direct from the company, but then again, no nosey parker can check to see if you are a shareholder and you can avoid getting junk 'investment' advice, ususally share tips for the next microsoft etc.
With the latter, you get the correspondence direct and there is no delay in getting them. you can also qualify easier for an shareholder perks.
In view of the Morrogh collapse, if you are using an Irish broker, you would be better in Sponsored Member of Crest as the shares are clearly yours and in the event of the broker going belly up, thre should be no difficulty in transferring to another broker. If in the nominee account and broker goes belly up, the liquidator owns the nominee stock.
