The lock-in gives Haier a 37.46 per cent interest in F&P Appliances, including its own 20 per cent shareholding, which falls short of the offer's 50 per cent minimum acceptance condition.
"What [the lack of SSH notices] tells you is that people are watching and waiting to see how it pans out," said Mark Lister, head of private wealth research at Craigs Investment Partners.
F&P Appliances' shares were trading at $1.22 yesterday afternoon - above the $1.20 per share Haier is offering for all the shares in the New Zealand firm it does not already own.
"Why would you accept now at $1.20 when you can sell on market for $1.22?" said Lister.
Grant Samuel's independent report valued the New Zealand whiteware maker at between $1.28 per share and $1.57 per share, prompting F&P Appliances' board to advise its shareholders to reject Haier's offer.
Meanwhile, the Business Herald understands negotiations are taking place between representatives of Haier and institutional shareholders in F&P Appliances over the offer.
And a market source said F&P Appliances' independent directors were also in talks with the Chinese firm over increasing the offer price.
F&P Appliances chairman Keith Turner said yesterday that he could not comment on "what might be under negotiation" and a Haier spokesman denied any talks were taking place with institutions.
The offer closes on November 6, but Haier has only until Friday to tell F&P Appliances investors if it will make any changes to the offer unless it extends the offer period.
