I note the MB class action only covers parties who purchased shares in Bellamy’s on or after:
14 April 2016 and who held some or all of those shares until 1 December 2016 (the “First Period”);
OR
December 2016 and who held some or all of those shares until 9 December 2016 (the “Second Period”

Does anyone know if any class action covers shares purchased before 14 April 2016 ?

..........seems to me, all holders suffered as a result of BAL breaches
