With a majority of AWB Ltd A-class directors opposed to removal of Article 2 from AWB Ltd's constitution, WGA says grower (A class) shareholders should not to give up control of the massive advantage AWB holds in the export wheat market.

"The opinion expressed by a majority of A-class directors that the proposed changes are not in the interests of AWB, should not be lost on A-class shareholders," WGA chairman Bob Iffla said.

"In the voting papers sent to growers the consequences of giving up A-class shareholder control has been made very clear with the AWB board saying that once A-class shareholder control is removed it will 'focus its resources in areas that generate the best return for shareholders'.

"Focusing on what gives the best return to investor shareholders will not necessarily be in the best interests of Australia's wheat growers who needed to fight to have over 60 years of wheat marketing knowledge and intellectual property funded by wheat growers under wheat grower control."

Mr Iffla said the vote will come down to a choice by wheat growers between ensuring there continues to be a grower controlled entity required to maximise grower returns, or giving over control to investor shareholders to exploit for their own benefit.
