Based on a (very) old set of accounts (2006) [as I dont have recent ones to hand] we had 1,891,681 'ordinary' shares issued at that time. We also had 600,000 'A' Ordinary shares, 300,000 'B' Ordinary shares and 3 'C' Ordinary shares. Each share had a nominal value of £1 so technically our share issue was worth a little under £2.8m
I am not sure of the details, and someone will likely come along and explain it but I believe that the 1.9M Ordinary shares are the "voting" shares which shareholders big and small hold which give you the right to come along to AGMs and vote. A,B, & C shares are of the same value and although they allow you to attend AGMs etc they hold no voting rights. Think the "C" shares were Caledonian, Thistle, and INE (but could be wrong).
However ... at the end of the day, the shares are worth only what someone is willing to pay for them ..... and a little over £1m would indeed buy more than 50% of the club .... would not be selling mine though .... its only 250 shares but its my own little bit of ICT that I will own forever and which I never expected any return on anyway.
Cant really comment on the speculation about the offer until we know more details and who and what is involved. If its someone (or a group) with the long term good of ICT in their hearts then its definitely to be considered ... but if its a "benefactor" with no prior connection then I would be very wary.
