annual general meeting

CEO sprouting spin spin spin,thinks .. shareholders are interested in good works for schools etc .Asked a question re NAB given as $5.06 that is net asset backing ,how did they arrive at that figure it was shown prominently on big screen.Questioner also asked re NTA was told NAB was NTA questioner asked three times was this correct was assured it was.Chairman ;max the axe;then came on board and told questioner to talk To CFO after the meeting . QUESTIONER took this up withCFO after meeting and wasinformed NTA was a negative figure.....confusing and worrying that well paid CEO not aware of this
