Disqualification as a director does not prevent an individual from owning shares, although it does say a lot about how an individual has conducted themselves.
As the liquidator did not pursue the legal transfer of shares from Reactive to Mr Abbott they must have concluded that Reactive received appropriate value for them. Even if this was, as likely, nothing.
Mt Abbott had considerable sums of money owed to him by the club and in return "wrote off" this amount against ongoing hospitality at games for a considerable number of years. He has a box at the club which he or friends and family used regularly last season after eating in the lounge. as such it should be noted whilst he has made amounts available to the Club these have not been "donations'. (An approach continued by Mr Croad but not by Mr Steele, who "wrote off" significant sums in exchange for shares)
Whilst none of this indicates what Mr Abbotts personal wealth at present is, I believe the sceptics who were not convinced by his arguments concerning his purchasing the Shay have been proved 100% correct.
