Seems the INEOS bid is structured to buy just the Glazers class A and B shares at a premium. The idea is the group will buy 31% of the remaining shares listed on the NY Stock Exchange at a much lower price further down the years. It's very likely those shares will go down due to no dividends being paid and the group showing losses with all the repair work, interest payments and infrastructure works required.
Basically, it's a cleverly structured deal means INEOS pays less for the club to the detriment of the club and smaller shareholders. Obviously, this is just my take on the situation.
