what % ?

what % of shares need to be committed to alsaf before Dulux caves in and agrees to an extra 27c dividend with franking credits attached to be paid from their now 1.90 take over offer.
Obviously at least 10% to avoid compulsory takeover limit,
but I believe need at least 20/25% before dulux will submit to pay the price for a quick solution and board would probably recommend it to all shareholders. In a lot of ways the alsaf is a poll for the directors of not only als but dulux as well
